Insulation in Oak Lawn, IL

Crawl space encapsulation and vapor barrier work in Oak Lawn almost always starts with the same phone call: a homeowner tired of musty air creeping up through the floors of a 1960s brick ranch. The village’s uniform stock of single-story and 1.5-story brick-clad homes built between 1950 and 1975 sits on full basements or slabs, and the crawl spaces under those homes were never designed to handle Illinois humidity. Most jobs we do in Oak Lawn involve sealing the crawl space, adding a vapor barrier, and then moving upward to the attic and walls, because the whole house was built before energy codes existed. Call (855) 657-3403 and a live person answers, 24/7.

Why Oak Lawn Homes Are Different

Oak Lawn sits in IECC Climate Zone 5A, where polar vortex events regularly push temperatures below 0°F and the seasonal swing can exceed 120°F from summer high to winter low. That kind of spread punishes under-insulated attics and rim joists hard. The village grew explosively from roughly 1950 to 1975, leaving a very uniform stock of brick ranch homes and 1.5-story bungalows with full basements or slab foundations built under pre-energy-code standards. The brick exterior gives homeowners a false sense of thermal security, because wall cavities in this era of construction were typically left empty or packed with minimal rock wool that has since settled and degraded.

One pattern we see repeatedly in Oak Lawn: the attached garage additions common on 1960s and 1970s ranch homes have completely uninsulated ceilings separating the garage from a bedroom or living space above. That single gap is a fire code concern and the biggest source of cold-floor complaints that bring homeowners to call us in the first place. The same freeze-thaw cycling that stresses Chicago-area infrastructure drives significant air infiltration through the band joists of Oak Lawn’s basement-heavy housing stock.

Our Main Oak Lawn Services

Two services dominate our work in Oak Lawn, and they usually go together. Blown-in attic insulation brings under-code attics up to current R-49 standards, while wall insulation retrofits address the empty or settled cavities behind all that brick.

Attic Insulation in Oak Lawn

Oak Lawn attics from the 1950s through 1970s were built with degraded early fiberglass batts or settled rock wool that performs well below Illinois Energy Code’s current R-49 attic requirement. We remove or top up that old material, air seal the attic floor, and blow in fresh insulation to bring the whole assembly up to code. For the full breakdown of attic insulation work in Oak Lawn, see Attic Insulation in Oak Lawn.

Crawl Space Encapsulation & Vapor Barrier in Oak Lawn

Crawl space encapsulation in Oak Lawn is not a luxury upgrade; it’s the fix for a design flaw baked into the village’s housing stock. Homes built during the 1950s-1975 boom arrived with vented crawl spaces and dirt floors, which pull humid air into the house all summer and cold air all winter. That moisture travels upward through floor joists, and in a Zone 5A climate, it condenses, feeds mold, and drives up heating bills. Our Crawl Space Encapsulation & Vapor Barrier service seals the entire space with a reinforced liner, closes the vents, and conditions the space so it stops fighting the rest of the house.

Crawl Space Vapor Barrier

Signs you need it

You smell musty air near the floors, see condensation on ductwork or pipes in the crawl space, or notice damp spots on the foundation walls after rain.

What it costs in Oak Lawn

A 12-mil or 20-mil reinforced vapor barrier installed over a crawl space floor in Oak Lawn typically runs $4-$8 per square foot, depending on the liner thickness and how much prep the floor needs.

How we do it

We clear the floor of debris, level high spots, run the liner up the walls, and seam-seal every joint. We then fasten it to the foundation with mechanical attachments so it stays put.

Crawl Space Moisture Control

Signs you need it

Your crawl space has standing water after storms, efflorescence on the block walls, or a relative humidity reading above 60% on a summer day.

What it costs in Oak Lawn

Moisture control work, which often pairs a vapor barrier with drainage improvements, typically falls in the $2,000-$5,500 range for an average Oak Lawn crawl space.

How we do it

We identify where water is entering, install or repair perimeter drainage, add a sump pump if needed, and then seal the space with a full vapor barrier so humidity stays below 55%.

What Crawl Space Encapsulation & Vapor Barrier Costs in Oak Lawn

Item Typical range in Oak Lawn
Vapor barrier only (12-mil) $4-$8 per sq ft
Full encapsulation with drainage $2,000-$5,500
Dehumidifier installation $1,200-$2,200
Insulation replacement in crawl space $1.50-$3.50 per sq ft

Is crawl space encapsulation worth it in Oak Lawn?

Yes, especially for brick ranch homes with vented crawl spaces. Sealing the space stops humid summer air from condensing on floor joists and prevents the musty smell that rises through the living areas. Most Oak Lawn homeowners see lower humidity and fewer cold floors within the first week.

Can you encapsulate my crawl space in one day?

Most standard crawl spaces in Oak Lawn are encapsulated in a single visit. Larger spaces or those needing drainage work may take two days, but our crews arrive background-checked and uniformed and keep you updated on timing. Call (855) 657-3403 for a free estimate.

Spray Foam Insulation in Oak Lawn

Spray foam insulation in Oak Lawn solves a problem that fiberglass never could: the gap between the brick veneer and the framed wall behind it. That gap, common in the village’s 1950s-1970s construction, lets outside air circulate behind the brick and find its way into bedrooms. We use Spray Foam Insulation to air seal and insulate in one step, which matters when winter lows hit below zero and summer highs push past 90°F.

Rim Joist Spray Foam

Signs you need it

Your basement feels drafty near the top of the foundation wall, your heating bills spike every January, or you can feel cold air moving around the band joist where the floor meets the foundation.

What it costs in Oak Lawn

Rim joist spray foam in Oak Lawn typically runs $1.50-$3.50 per board foot, and a standard full basement usually takes 300-600 board feet total.

How we do it

We clean the rim joist area, apply closed-cell foam to the band joist and top plates, and build up enough thickness to stop air movement. Most jobs finish in one visit.

Garage Ceiling Spray Foam

Signs you need it

The bedroom above your attached garage is always the coldest room in the house, or you can feel cold air coming from the garage into the house through the ceiling.

What it costs in Oak Lawn

Garage ceiling spray foam in Oak Lawn usually falls in the $1,500-$3,500 range depending on the square footage and whether we’re removing old drywall first.

How we do it

We apply closed-cell foam directly to the underside of the garage ceiling, creating an air and thermal barrier between the unconditioned garage and the living space above. This also addresses the fire code concern common to Oak Lawn’s attached garage additions.

What Spray Foam Insulation Costs in Oak Lawn

Item Typical range in Oak Lawn
Rim joist spray foam $1.50-$3.50 per board foot
Open-cell attic spray foam $2.50-$5.00 per sq ft
Closed-cell wall spray foam $3.00-$6.00 per sq ft
Garage ceiling spray foam $1,500-$3,500

Is spray foam safe for older Oak Lawn homes?

Yes. Closed-cell and open-cell spray foams used by licensed installers are fully cured and inert within 24 hours, and they’re approved for use in existing homes. We have crews experienced with the specific wall-cavity conditions of 1950s-1970s Oak Lawn construction.

Will spray foam make my house too tight?

No, not when paired with proper mechanical ventilation. We evaluate your home’s ventilation during the job and recommend solutions if needed. Spray foam’s real effect is stopping the uncontrolled air leaks that cost money and comfort. Call (855) 657-3403 and ask about the 90-Day Done Right Promise.

Blown-In Insulation in Oak Lawn

Blown-in insulation is the most common retrofit we do in Oak Lawn because it works with the existing structure instead of against it. Homes built during the village’s post-war boom usually have attics with degraded fiberglass batts or settled rock wool that need a complete R-49 top-up, and wall cavities that were never insulated at all. Our Blown-In Insulation service brings both up to current Illinois Energy Code without tearing open walls or ceilings.

Blown-In Fiberglass

Signs you need it

Your attic insulation measures below R-49, you can see the tops of the ceiling joists, or your upstairs rooms are noticeably hotter than the rest of the house in August.

What it costs in Oak Lawn

Blown-in fiberglass attic insulation in Oak Lawn typically runs $1.50-$3.50 per square foot, including air sealing and bringing the depth up to R-49.

How we do it

We air seal penetrations, lay down any needed baffles, and blow Owens Corning or Johns Manville fiberglass to the specified depth. The material settles very little over time, so the R-value you pay for is the R-value you keep.

Dense-Pack Wall Insulation

Signs you need it

Your Oak Lawn brick ranch has ice-cold walls in winter, you can feel drafts around outlets on exterior walls, or your heating bills stay high even after attic work.

What it costs in Oak Lawn

Dense-pack wall insulation in Oak Lawn, installed from the exterior through drilled holes that are then sealed, typically costs $2.50-$4.00 per square foot of wall area.

How we do it

We drill small access holes through the brick and sheathing, then blow cellulose or fiberglass at high pressure to completely fill the wall cavity. The result is an air seal and insulation in one pass, and we patch every hole so the brick face looks clean.

What Blown-In Insulation Costs in Oak Lawn

Item Typical range in Oak Lawn
Blown-in attic fiberglass (R-49) $1.50-$3.50 per sq ft
Blown-in cellulose attic top-up $1.20-$2.80 per sq ft
Dense-pack wall insulation $2.50-$4.00 per sq ft
Complete attic air seal + blow-in $2.50-$5.00 per sq ft

Can you blow insulation into my existing Oak Lawn walls without removing the brick?

Yes. We drill through the mortar joints or brick face, blow the insulation in, and seal the holes with color-matched mortar or caulk. The process takes a day for most single-story homes, and the exterior looks like it did before.

How much of a difference will blown-in insulation make in Oak Lawn?

Homeowners we work with in Oak Lawn typically see a 15-25% reduction in heating and cooling costs after bringing attics to R-49 and filling empty wall cavities. The exact number depends on your home, but the comfort difference in the coldest weeks of January is immediate.

Radiant Barrier Installation in Oak Lawn

Radiant barrier installation in Oak Lawn targets the summer problem: the sun beating down on dark asphalt shingles and turning the attic into an oven. Our Radiant Barrier Installation service installs a reflective foil layer that bounces radiant heat back out instead of letting it soak into your insulation and ceiling.

Attic Radiant Barrier

Signs you need it

Your second floor is unusable in July, your air conditioner runs constantly on hot afternoons, or your attic temperature exceeds 130°F on a sunny day.

What it costs in Oak Lawn

Attic radiant barrier installation in Oak Lawn typically costs $1.25-$3.00 per square foot of attic floor area when installed over existing insulation.

How we do it

We roll the foil across the top of the existing insulation or staple it to the underside of the rafters, then seal edges and overlaps. The reflective surface stays dusty for years with minimal maintenance, and the barrier works alongside whatever insulation you already have.

Radiant Barrier Roof Deck

Signs you need it

Your attic is vented but still brutally hot, your shingles are dark, and you’re not planning to convert the attic to living space anytime soon.

What it costs in Oak Lawn

Roof deck radiant barrier attached to the underside of rafters typically runs $1.50-$3.50 per square foot of roof area in Oak Lawn.

How we do it

We staple a double-sided foil to the bottom of the roof deck, leaving an air gap between the foil and the deck. In a Zone 5A climate, this works best in vented attics, and we check your ridge and soffit vents before starting.

What Radiant Barrier Installation Costs in Oak Lawn

Item Typical range in Oak Lawn
Attic floor radiant barrier $1.25-$3.00 per sq ft
Roof deck radiant barrier $1.50-$3.50 per sq ft
Radiant barrier + ventilation check $1.75-$4.00 per sq ft
Garage ceiling radiant barrier $1.00-$2.50 per sq ft

Does radiant barrier work in Oak Lawn winters?

Radiant barrier is a summer tool, not a winter one. It reduces heat gain from the sun, which is your biggest cooling cost driver. In winter, your primary defense is the insulated attic floor below the barrier, which keeps the heat in the living space.

Is radiant barrier worth it for an older Oak Lawn brick ranch?

If your attic temperature climbs above 120°F in summer, yes. Combined with proper attic insulation, a radiant barrier can reduce cooling costs by 10-15% and extend the life of your AC system. Call (855) 657-3403 and we’ll tell you if your attic is a good candidate.

Insulation Removal & Replacement in Oak Lawn

Insulation removal and replacement in Oak Lawn is often the first step before any other attic work, because the original material in these 1950s-1970s homes has been through decades of freeze-thaw cycles, roof leaks, and rodent activity. Our Insulation Removal & Replacement service removes the old, compromised material and starts fresh, which gives you a clean slate for air sealing and new insulation.

Attic Insulation Removal

Signs you need it

Your attic insulation is compressed, blackened near the eaves, or has visible rodent droppings mixed into it. Any of these means the material is no longer doing its job.

What it costs in Oak Lawn

Attic insulation removal in Oak Lawn typically runs $1.00-$2.50 per square foot, including bagging and disposal of the old material.

How we do it

We run a high-powered vacuum from the attic to a truck-mounted collection bag, pulling out every trace of old fiberglass, rock wool, or cellulose. The attic is left bare and ready for air sealing and new insulation.

Vermiculite & Old Insulation Removal

Signs you need it

Your home was built before 1980 and has a pebbly, gray-brown insulation in the attic. Vermiculite from the Libby, Montana mine may contain asbestos and should not be disturbed without testing.

What it costs in Oak Lawn

Vermiculite removal in Oak Lawn varies based on testing results, but typical removal and disposal ranges from $3.00-$7.00 per square foot when asbestos abatement protocols are required.

How we do it

We test first, then follow all required containment and disposal procedures. If the vermiculite is asbestos-free, standard removal applies. If not, we work with certified abatement partners to handle it safely and legally.

What Insulation Removal & Replacement Costs in Oak Lawn

Item Typical range in Oak Lawn
Attic insulation removal $1.00-$2.50 per sq ft
Contaminated insulation removal $2.00-$4.00 per sq ft
Vermiculite removal $3.00-$7.00 per sq ft
Full removal + new blown-in insulation $3.50-$7.50 per sq ft

Do I really need to remove old insulation in my Oak Lawn attic before adding new?

Not always. If the old material is dry, free of pests, and not compressed, a top-up is fine. But if you have rodent activity, water damage, or vermiculite, removal is the right call. We’ll give you an honest recommendation during your estimate.

How long does insulation removal take in Oak Lawn?

Most attics in Oak Lawn are fully removed and replaced in one day. Larger homes or those with vermiculite may take two days, but our crews complete most jobs in a single visit. The 90-Day Done Right Promise applies either way.

Attic Air Sealing in Oak Lawn

Attic air sealing in Oak Lawn stops the stack effect that pulls heated air out of your house and cold air in through every gap around wires, pipes, and lights. In a village where winter lows regularly drop below zero, those gaps are expensive. Our Attic Air Sealing service seals every penetration before any new insulation goes in.

Attic Floor Air Sealing

Signs you need it

You can feel cold drafts near ceiling fixtures in winter, your furnace runs constantly, or you see dark spots on the attic insulation where air is pushing dust through.

What it costs in Oak Lawn

Attic floor air sealing in Oak Lawn typically runs $1.00-$2.50 per square foot of attic floor area, including sealing around all penetrations and top plates.

How we do it

We pull back the existing insulation around every penetration, seal each gap with closed-cell foam or caulk, and then re-cover the area. This includes the tops of interior and exterior walls, which are the biggest leak paths in Oak Lawn’s 1960s framing.

Can Light & Duct Boot Sealing

Signs you need it

Your recessed can lights are hot in summer and cold in winter, or your upstairs rooms never seem to get enough airflow from the ducts.

What it costs in Oak Lawn

Can light and duct boot sealing typically adds $15-$35 per fixture or boot in Oak Lawn, depending on access and the type of housing.

How we do it

We seal the gap between each can light or duct boot and the drywall with fire-rated sealant, then add a foam or metal cover where needed. This stops both air leaks and heat transfer at the fixture.

What Attic Air Sealing Costs in Oak Lawn

Item Typical range in Oak Lawn
Complete attic floor air sealing $1.00-$2.50 per sq ft
Can light sealing $15-$35 per fixture
Duct boot sealing $15-$35 per boot
Attic hatch sealing + insulation $200-$400 per hatch

Why is air sealing more important than adding insulation in Oak Lawn?

Because insulation slows heat transfer but doesn’t stop air movement. A leaky attic floor lets your heated air escape and pulls cold air in, no matter how much insulation you have. Air sealing stops that flow, which is why we do it before any blown-in insulation job.

How do I know if my Oak Lawn attic needs air sealing?

If you see dirty insulation, feel drafts around ceiling fixtures, or your furnace runs constantly on cold days, your attic is leaking. A blower door test during a home energy audit will quantify it. Call (855) 657-3403 and we’ll schedule one.

Wall Insulation in Oak Lawn

Wall insulation in Oak Lawn is the sleeper improvement that most homeowners overlook, because the brick exterior looks solid and permanent. Behind that brick, most walls from the 1950s-1970s boom are either empty or packed with settled rock wool that does almost nothing. Our Wall Insulation service fills those cavities without gutting rooms, using injection foam or drill-and-fill methods that work from the exterior or interior.

Injection Foam Wall Insulation

Signs you need it

Your exterior walls feel cold to the touch in winter, your heating bills stay high even after attic work, or you can feel drafts near outlets on exterior walls.

What it costs in Oak Lawn

Injection foam wall insulation in Oak Lawn typically runs $2.50-$4.50 per square foot of wall area, including drilling, filling, and patching.

How we do it

We drill small holes through the brick or drywall, inject expanding foam at low pressure so it fills the cavity completely, then patch the holes with color-matched mortar or compound. The foam air seals and insulates in one step.

Interior Wall Soundproofing

Signs you need it

You can hear conversations through bedroom walls, or you have a home office or media room that needs acoustic separation from the rest of the house.

What it costs in Oak Lawn

Interior wall soundproofing in Oak Lawn typically costs $2.00-$4.00 per square foot using dense-pack cellulose or mineral wool, depending on the wall construction.

How we do it

We dense-pack cellulose or Rockwool into the interior wall cavities, which deadens sound transmission between rooms. This works especially well in Oak Lawn’s 1.5-story bungalows where bedrooms share walls with main-floor living spaces.

What Wall Insulation Costs in Oak Lawn

Item Typical range in Oak Lawn
Injection foam wall insulation $2.50-$4.50 per sq ft
Drill & fill cellulose walls $2.00-$3.50 per sq ft
Interior wall soundproofing $2.00-$4.00 per sq ft
New construction wall insulation $1.00-$2.50 per sq ft

Can you insulate my Oak Lawn walls without damaging the brick?

Yes. We drill through mortar joints or brick face, fill the cavity, and patch with color-matched mortar. On most Oak Lawn ranch homes, the holes are nearly invisible after patching, and the brick structure is not affected.

How do I know if my Oak Lawn walls are insulated?

Remove an outlet cover on an exterior wall and look around the box with a flashlight. If you see empty space or just a thin layer of settled material, your walls need work. We can confirm with a thermal imaging scan during a home energy audit.

Attic Cleaning & Rodent Proofing in Oak Lawn

Attic cleaning and rodent proofing in Oak Lawn goes after the pests that find their way in through the same gaps that leak air: soffit vents, roof intersections, and the gaps around chimney chases. Rodents in an Oak Lawn attic don’t just damage insulation; they contaminate it, and their droppings create a health hazard that no amount of new insulation will fix. Our Attic Cleaning & Rodent Proofing service removes the contamination, cleans and sanitizes, and seals the entry points so they don’t come back.

Attic Cleanout

Signs you need it

You hear scratching in the ceiling at night, see droppings in the attic, or notice piles of torn-up insulation and nesting material near the eaves.

What it costs in Oak Lawn

A full attic cleanout in Oak Lawn typically runs $1,200-$3,000 depending on the attic size and the level of contamination, including removal of all old insulation and debris.

How we do it

We vacuum out everything: old insulation, droppings, nesting material, and debris. The attic is left bare and ready for sanitizing, air sealing, and new insulation.

Rodent Proofing & Exclusion

Signs you need it

You’ve had rodent activity in the attic, or you want to prevent it before it starts. Common entry points in Oak Lawn homes include soffit vents, gable vents, and gaps around the chimney.

What it costs in Oak Lawn

Rodent proofing and exclusion work in Oak Lawn typically ranges from $400-$1,500 depending on how many entry points need sealing and what type of hardware is required.

How we do it

We seal every gap with galvanized steel mesh, foam, or flashing, then install vent covers where needed. The goal is to make the attic physically inaccessible to rodents, not just to trap the ones already inside.

What Attic Cleaning & Rodent Proofing Costs in Oak Lawn

Item Typical range in Oak Lawn
Attic cleanout $1,200-$3,000
Sanitizing & decontamination $500-$1,500
Rodent proofing & exclusion $400-$1,500
Full restoration (cleanout + seal + new insulation) $3,500-$8,000

Do I need to replace my insulation after rodent activity in my Oak Lawn attic?

Usually, yes. Rodent urine and droppings contaminate insulation and create a health hazard. We recommend removing the contaminated material, sanitizing the space, and installing new insulation as a complete restoration.

How fast can you respond to a rodent problem in Oak Lawn?

We schedule attic cleanouts and rodent proofing in Oak Lawn within a few days in most cases. If you’re hearing active scratching, call (855) 657-3403 and we’ll get you on the schedule. A live person answers 24/7.

Home Energy Audit in Oak Lawn

A home energy audit in Oak Lawn is the diagnostic starting point that makes every other service smarter, which is why we recommend it before any major insulation work. In a village of 1950s-1970s brick ranches, the audit tells you exactly where your house is leaking air and losing heat, so you spend money on the fixes that matter. Our Home Energy Audit combines blower door testing, thermal imaging, and a room-by-room inspection into one clear report.

Blower Door Test

Signs you need it

Your energy bills are high but you don’t know why, or you’ve been told your house is leaky but want hard numbers before committing to air sealing work.

What it costs in Oak Lawn

A blower door test as part of a complete home energy audit in Oak Lawn typically runs $300-$600, depending on home size and the scope of the audit.

How we do it

We mount a calibrated fan in an exterior door frame, depressurize the house, and measure exactly how much air is leaking in. The number tells us how much air sealing is needed and where to start first.

Thermal Imaging Inspection

Signs you need it

Certain rooms are always cold or hot, you can feel drafts but can’t locate the source, or you want visual proof of where insulation is missing or settled.

What it costs in Oak Lawn

A thermal imaging inspection is typically included with the full audit, or runs $150-$350 as a standalone service in Oak Lawn.

How we do it

We scan every wall, ceiling, and floor with an infrared camera that shows temperature differences as colors. Missing insulation, air leaks, and moisture problems all show up clearly, and we document everything with images you can keep.

What Home Energy Audit Costs in Oak Lawn

Item Typical range in Oak Lawn
Complete home energy audit $300-$600
Blower door test only $150-$350
Thermal imaging inspection $150-$350
Duct leakage test $150-$300

Do I need a home energy audit before insulation work in Oak Lawn?

Not always, but it’s the smartest way to avoid wasting money. The audit identifies exactly where your house is leaking, so we can target the fixes that give you the most comfort and bill savings for the least investment.

How long does a home energy audit take in Oak Lawn?

Most audits in Oak Lawn take 2-4 hours depending on home size and the tests involved. You’ll get a written report the same day with our recommendations and pricing. Call (855) 657-3403 and ask about the $89 Seasonal Tune-Up.

FAQs About Insulation in Oak Lawn, IL

How quickly can you schedule insulation work in Oak Lawn?

We can usually get an inspector out to an Oak Lawn home within a few business days and start work once you approve the estimate. Most attic or wall insulation jobs finish in a single day, and crawl space or full-home projects typically take one or two days depending on access.

Do I need a permit for insulation work in Oak Lawn?

Most standalone attic, wall, or crawl space insulation work does not require its own permit in Oak Lawn. If the insulation is part of a larger renovation that already needs a permit, the local energy code may require the new work to meet current insulation standards.

How does your written estimate process work?

We inspect the attic, walls, or crawl space in person, measure the area, and note anything that affects access or cost before writing up a fixed, itemized estimate. You approve the price in writing before the crew is scheduled, and it does not change once work begins.

Do you serve areas outside Oak Lawn?

We work throughout Oak Lawn and the surrounding communities, so homeowners in nearby neighborhoods and towns can use the same crews, the same pricing, and the same written estimate process without needing to find a separate local contractor.

What happens to the old insulation you remove?

We remove old insulation completely before installing anything new, bagging it for disposal and treating material that shows signs of rodent activity, mold, or heavy contamination with extra care. Attics with vermiculite or heavily soiled material get additional containment steps before removal begins.

What Oak Lawn Customers Say

★★★★★ 4.9 from 8+ reviews

"Injection foam in the walls of our 1950s house - no drywall demolition, just small holes patched and painted the same day. The street noise in the front bedroom is half what it was."

- Yasmin Farah

"Upstairs was ten degrees hotter than downstairs every summer. They pulled the attic to bare joists, air-sealed every can light and top plate first, then blew it to R-49. First August in this house where the bedrooms and the living room read the same on the thermostat."

- Marcus Hale

"Rodents had been in the attic for years before we bought the place. They vacuumed everything out, sanitized, sealed the entry points with mesh and foam, and only then put new insulation down. Photos of every stage before I paid."
