Insulation in Humble, TX
Crawl space encapsulation and vapor barrier work in Humble, TX typically runs $2,600-$8,700 depending on square footage and how much standing water or mold you’re dealing with. Homes here sit directly in the Lake Houston flood corridor, so the moisture problem is different from what you’d find in higher-elevation Houston suburbs. Most Humble jobs are completed in a single visit, and a live person answers when you call (855) 657-3403.
Why Humble Homes Are Different
Humble’s position adjacent to Lake Houston and the West Fork San Jacinto River means ambient humidity regularly exceeds 85-90% on summer mornings. That’s not a comfort detail; it’s a vapor drive problem. Moisture pushes into every unsealed attic and wall cavity, and July attic temperatures hitting 140-150°F accelerate the breakdown of older fiberglass. The housing stock spans 1940s-1970s wood-frame homes in the original townsite near Downtown Humble through large waves of 1980s-2000s tract construction, and many of the older homes were built with minimal or no wall insulation. Then Hurricane Harvey flooded thousands of properties in 2017, and plenty of rebuilds used code-minimum fiberglass that’s now degraded. What’s unique to Humble is the split condition: brand-new lower-wall insulation sitting next to untouched, decades-old material a few feet higher. You won’t see that pattern in neighborhoods that stayed dry.
Our Main Humble Services
Humble homeowners call us most often for two jobs: attic insulation that’s been cooked and compressed by years of 140°F summers, and crawl spaces that stay damp nine months out of the year.
Attic Insulation in Humble
Older Humble homes lose a staggering amount of cooling through under-insulated attics. We pull back the old batts, air seal the floor, and blow fresh coverage to R-38 or higher. In post-Harvey rebuilds we frequently find fiberglass that was installed fast and has already settled below code. Our Attic Insulation in Humble page covers what a typical job looks like here, including how we handle the split-condition wall cavities common in Atascocita-area rebuilds.

Crawl Space Encapsulation & Vapor Barrier in Humble
Humble crawl spaces stay wet. The water table near Lake Houston and the West Fork San Jacinto keeps ground moisture high through most of the year, and once that moisture gets under a pier-and-beam home, it feeds mold, warps joists, and pushes musty air into your living space. Encapsulation stops that cycle by sealing the floor and walls with a reinforced vapor barrier, and in Humble we recommend it far more often than we would for homes on higher ground. It’s the single highest-impact fix for a drafty, damp, or odd-smelling older home here. Our Crawl Space Encapsulation & Vapor Barrier work includes a written 90-Day Done Right Promise, because a vapor barrier only works if every seam and penetration is sealed correctly.
Crawl Space Vapor Barrier
Signs you need it
You smell must or mildew when the AC kicks on, or you see condensation on ductwork and floor joists. In Humble’s humidity, even a damp dirt crawl space will eventually rot subflooring.
What it costs in Humble
Crawl space vapor barrier installation in Humble typically runs $1,200-$3,500 depending on square footage and access.
How we do it
We lay a reinforced polyethylene liner across the floor, run it up the foundation walls, and seal every seam and pier penetration with tape and mechanical fasteners.
Crawl Space Encapsulation
Signs you need it
Standing water after heavy rain, high indoor humidity that won’t drop below 60%, or visible mold on joists. Homes in the original Humble townsite with 1940s-1970s wood framing are particularly vulnerable.
What it costs in Humble
Full crawl space encapsulation in Humble typically runs $3,500-$8,700 depending on square footage, drainage needs, and whether a sump pump is required.
How we do it
We seal the entire crawl space: vapor barrier on floor and walls, closed-cell foam on rim joists and foundation walls, a dehumidifier sized for the space, and drainage correction where water pools.
What Crawl Space Encapsulation & Vapor Barrier Costs in Humble
| Item | Typical range in Humble |
|---|---|
| Crawl space vapor barrier | $1,200-$3,500 |
| Full crawl space encapsulation | $3,500-$8,700 |
| Crawl space insulation | $1,200-$3,600 |
| Crawl space moisture control with dehumidifier | $1,800-$4,500 |
Is crawl space encapsulation worth it in Humble?
Yes, for most pier-and-beam homes here the payback is faster than in drier parts of Texas. Sealing the crawl space cuts indoor humidity, reduces AC load, and protects joists from the constant moisture rising off Lake Houston-adjacent soil.
Can you get mold out of a Humble crawl space?
We remove contaminated insulation, treat visible mold on framing, then encapsulate so it can’t return. Call (855) 657-3403 for an inspection and an exact quote; estimates are free.
Spray Foam Insulation in Humble
Spray foam earns its keep in Humble because it does two jobs at once: it insulates and it air seals. That matters in a climate where 90% morning humidity pushes vapor into wall cavities and attics from March through October. Closed-cell foam in particular resists the moisture that has degraded countless fiberglass installs here since Harvey. Our Spray Foam Insulation team uses Icynene and Demilec open-cell and closed-cell products, backed by the 90-Day Done Right Promise.
Closed-Cell Spray Foam
Signs you need it
You have a damp crawl space or an attic that smells musty after rain. Closed-cell foam is a vapor barrier, so it’s the right choice for Humble homes dealing with persistent moisture.
What it costs in Humble
Closed-cell spray foam in Humble typically runs $2.00-$3.50 per board foot installed, with most whole-attic jobs landing between $5,000 and $12,000.
How we do it
We prep the area, apply the foam in lifts to the specified depth, and trim to code. The foam cures in minutes and adds structural strength to the framing.
Rim Joist Spray Foam
Signs you need it
Cold floors in winter, high summer humidity, or mouse droppings along sill plates. Rim joists are the leakiest part of a Humble crawl space.
What it costs in Humble
Rim joist spray foam in Humble typically runs $1,800-$4,500 for an average perimeter, including prep and cleanup.
How we do it
We clean each bay, apply closed-cell foam to seal the rim completely, and check for gaps around plumbing and electrical penetrations.
What Spray Foam Insulation Costs in Humble
| Item | Typical range in Humble |
|---|---|
| Open-cell spray foam (attic) | $0.50-$1.50 per board foot |
| Closed-cell spray foam | $2.00-$3.50 per board foot |
| Rim joist spray foam | $1,800-$4,500 |
| Spray foam roof deck | $2.50-$6.50 per square foot |
Is spray foam safe after it cures?
Yes. We vacate the home during application and for the manufacturer-specified re-entry window, usually about 24 hours. After full cure, the foam is inert and off-gassing stops. Ask us about the specific product before scheduling if you have sensitivities.
Open-cell or closed-cell for a Humble attic?
Closed-cell if moisture is the driving concern; its vapor-barrier properties make sense near Lake Houston. Open-cell works well for attic roof decks where you want air sealing and sound dampening at a lower cost. Call (855) 657-3403 for a recommendation based on your home.
Blown-In Insulation in Humble
Blown-in insulation is the workhorse fix for Humble attics that have settled, compressed, or never had enough coverage. The 140-150°F attic temperatures we get in July and August cook fiberglass batts over time, and post-Harvey rebuilds often settled within a few years. Blown-in cellulose or fiberglass fills gaps and gets you to R-38 fast. Our Blown-In Insulation installs use Owens Corning and GreenFiber products, and most Humble jobs finish in one visit.
Blown-In Cellulose
Signs you need it
Your attic insulation is uneven, compressed, or you can see the tops of joists. Cellulose settles less than loose fiberglass and fills odd cavities better in older Humble homes.
What it costs in Humble
Blown-in cellulose attic insulation in Humble typically runs $1.00-$2.50 per square foot installed.
How we do it
We air seal first, then blow cellulose to a consistent depth across the entire attic floor, checking coverage with a depth gauge every few feet.
Dense-Pack Wall Insulation
Signs you need it
Rooms that never hold temperature, or walls that feel cold to the touch in winter. Many 1940s-1970s Humble homes have empty 2×4 wall cavities.
What it costs in Humble
Dense-pack wall insulation in Humble typically runs $1,500-$4,500 per home depending on wall area and access.
How we do it
We drill small access holes, blow cellulose at high pressure until the cavity is fully dense-packed, then patch and texture-match the holes.
What Blown-In Insulation Costs in Humble
| Item | Typical range in Humble |
|---|---|
| Blown-in cellulose (attic) | $1.00-$2.50 per sq ft |
| Blown-in fiberglass (attic) | $0.90-$2.10 per sq ft |
| Dense-pack wall insulation | $1,500-$4,500 |
| Blown-in top-up over existing | $0.70-$1.50 per sq ft |
How much blown-in insulation does a Humble attic need?
R-38 is the practical target for our climate zone, which means roughly 13-14 inches of cellulose or 16-18 inches of loose fiberglass. Many Humble attics we inspect are sitting at R-11 or less. Call (855) 657-3403 and we’ll measure yours.
Can you blow insulation over old fiberglass?
Usually yes, if the old material is dry and mold-free. We inspect first; in post-Harvey homes with suspect material, removal is the safer call. The $50 Off Any Repair Over $250 discount applies to top-up jobs over that amount.
Radiant Barrier Installation in Humble
Radiant barrier makes a bigger difference in Humble than in almost any other Houston suburb because our attic temperatures spike so hard. When the roof deck hits 150°F in August, radiant heat pours down into your insulation and from there into your ceilings. A foil radiant barrier reflects that heat back toward the roof before it ever reaches your living space. Our Radiant Barrier Installation work pairs well with blown-in insulation and attic air sealing, and all of it carries the 90-Day Done Right Promise.
Attic Radiant Barrier
Signs you need it
Your upstairs rooms run 5-10°F hotter than downstairs in summer, or your AC runs constantly in July and August. Humble attics are the hottest part of the house.
What it costs in Humble
Attic radiant barrier installation in Humble typically runs $1,200-$3,500 depending on roof deck area and access.
How we do it
We staple reinforced foil to the underside of the roof deck, leaving a small air gap, and seal seams to maintain reflectivity.
Radiant Barrier & Ventilation
Signs you need it
Your attic has poor airflow, excessive heat, or condensation on the underside of the roof deck. Ventilation and radiant barrier work together in Humble’s humid climate.
What it costs in Humble
Radiant barrier plus ventilation correction in Humble typically runs $2,000-$5,500 depending on roof size and how many vents need adding.
How we do it
We assess intake and exhaust venting, add soffit or ridge vents as needed, then install the radiant barrier to reflect heat before it can load your insulation.
What Radiant Barrier Installation Costs in Humble
| Item | Typical range in Humble |
|---|---|
| Attic radiant barrier | $1,200-$3,500 |
| Radiant barrier foil (per sq ft) | $0.60-$1.20 per sq ft |
| Radiant barrier roof deck | $1,500-$4,200 |
| Radiant barrier & ventilation | $2,000-$5,500 |
Does radiant barrier work in a humid climate like Humble?
Yes, radiant barrier is about reflecting solar heat, not moisture. It works well in Humble because the cooling-season benefit is so large; the hotter your attic gets, the more heat it keeps out of your upstairs rooms.
Will radiant barrier damage my shingles?
No. The temperature increase on the roof deck is minor and well within shingle manufacturer tolerances. This is a proven product in Gulf Coast climates with decades of field data.
Insulation Removal & Replacement in Humble
Removal and replacement is the job Humble homeowners put off the longest, and it’s often the one that fixes the underlying problem. Harvey left thousands of homes with water-saturated or mold-colonized insulation that many owners patched rather than fully replaced. Even outside flood zones, 140°F attic heat degrades fiberglass over 15-20 years, and rodent or raccoon activity renders insulation unsanitary. Our Insulation Removal & Replacement work starts with a full inspection so you know exactly what’s coming out and why.
Attic Insulation Removal
Signs you need it
Visible mold, a persistent musty smell, or insulation that’s compressed and dark from years of heat and humidity. Humble’s summer attic temperatures accelerate this degradation.
What it costs in Humble
Attic insulation removal in Humble typically runs $1,000-$3,000 depending on attic size, access, and how much material is being pulled.
How we do it
We use a high-powered vacuum system to extract old insulation, bag it for disposal, and clean the attic deck before installing new material.
Contaminated Insulation Removal
Signs you need it
You see rodent droppings, urine stains, or nesting material in the attic. Contaminated insulation can’t be cleaned or covered; it has to come out and the attic sanitized before new material goes in.
What it costs in Humble
Contaminated insulation removal in Humble typically runs $1,500-$4,500 including sanitation of the attic space.
How we do it
We remove all affected material, sanitize and deodorize the attic deck and framing, then seal entry points so rodents can’t return.
What Insulation Removal & Replacement Costs in Humble
| Item | Typical range in Humble |
|---|---|
| Attic insulation removal | $1,000-$3,000 |
| Contaminated insulation removal | $1,500-$4,500 |
| Vermiculite & old insulation removal | $1,200-$3,800 |
| Insulation replacement (attic) | $1,800-$4,200 |
How do I know if my Humble attic insulation was damaged by Harvey?
If your home flooded and insulation wasn’t fully replaced above the visible water line, wall cavities and knee walls may still hold original material. We inspect these zones specifically in Humble, because the split-condition pattern is common here. Call (855) 657-3403 for an assessment.
Is it cheaper to remove or just add new insulation on top?
Adding on top is cheaper short-term, but if the old material is moldy, rodent-contaminated, or water-damaged, covering it just traps the problem. Removal costs more now and saves you a bigger remediation bill later.
Attic Air Sealing in Humble
Air sealing is the most underrated insulation job in Humble, and it’s usually the first thing we recommend before adding insulation. Every penetration between your living space and the attic, recessed lights, top plates, plumbing stacks, duct boots, is a path for conditioned air to escape and humid outdoor air to get pulled in. In a climate where morning humidity hits 90%, that’s a recipe for high bills and hidden mold. Our Attic Air Sealing work pays for itself faster here than in drier markets.
Attic Floor Air Sealing
Signs you need it
Your upstairs rooms are dusty, your AC runs constantly, or you feel drafts near interior walls. The attic floor is the largest unsealed surface in a Humble home.
What it costs in Humble
Attic floor air sealing in Humble typically runs $800-$2,500 depending on attic size and how many penetrations need addressing.
How we do it
We move back or temporarily remove insulation, seal every gap with foam or caulk, and reinstall insulation to proper depth.
Can Light & Duct Boot Sealing
Signs you need it
Recessed lights that feel hot, dust streaks on the ceiling, or ducts that sweat in summer. These penetrations leak air and pull humid attic air into your home.
What it costs in Humble
Can light and duct boot sealing in Humble typically runs $400-$1,200 depending on how many fixtures and boots need treatment.
How we do it
We seal around each light housing and duct boot with fire-rated foam and tape, then verify the seal with a smoke pencil before covering.
What Attic Air Sealing Costs in Humble
| Item | Typical range in Humble |
|---|---|
| Attic floor air sealing | $800-$2,500 |
| Top plate & penetration sealing | $600-$1,800 |
| Can light & duct boot sealing | $400-$1,200 |
| Attic hatch sealing | $150-$450 |
Should I air seal before adding insulation in Humble?
Yes, always. Blowing insulation over an unsealed attic floor wastes material and keeps letting humid air move through the assembly. In Humble’s humidity, the seal matters more than the R-value. Call (855) 657-3403 and we’ll assess yours.
How much can attic air sealing save on a Humble AC bill?
Most homeowners see 10-20% cooling savings after a proper air seal, sometimes more in older townsite homes with leaky framing. The exact number depends on your home, but the comfort improvement is immediate.
Wall Insulation in Humble
Wall insulation is where older Humble homes fail hardest. The 1940s-1970s wood-frame houses in the original townsite were often built with nothing in the 2×4 cavities, and they’ve been leaking conditioned air for fifty years. Even 1980s-2000s tract homes can have gaps, voids, and R-11 batts that don’t perform in our humidity. We retrofit walls from the inside or outside depending on access. Our Wall Insulation work includes dense-pack cellulose, injection foam, and drill-and-fill fiberglass, all covered by the 90-Day Done Right Promise.
Injection Foam Wall Insulation
Signs you need it
Rooms that won’t hold temperature, high summer bills, or walls that feel warm to the touch in the afternoon. Injection foam fills cavities completely and air seals as it cures.
What it costs in Humble
Injection foam wall insulation in Humble typically runs $2,500-$6,000 for an average single-story home.
How we do it
We drill small holes in each stud bay, inject slow-rise foam, and patch the holes. The foam expands to fill voids and seal around wiring and pipes.
Drill & Fill Wall Insulation
Signs you need it
You have an older Humble home with no wall insulation, or you’ve had one room that’s always cold in winter. Drill-and-fill is the standard retrofit for existing walls.
What it costs in Humble
Drill-and-fill wall insulation in Humble typically runs $1,800-$4,800 depending on wall area and exterior finish.
How we do it
We drill access holes from the exterior or interior, blow dense-pack cellulose or fiberglass into each cavity, and patch to match the existing surface.
What Wall Insulation Costs in Humble
| Item | Typical range in Humble |
|---|---|
| Injection foam wall insulation | $2,500-$6,000 |
| Drill & fill wall insulation | $1,800-$4,800 |
| Exterior wall insulation (new construction or open walls) | $1,000-$3,000 per wall section |
| Interior wall soundproofing | $1,500-$4,000 per room |
Does wall insulation help with humidity in Humble?
Yes, in combination with air sealing. Insulated walls stay closer to indoor temperatures, which reduces the condensation that forms when warm humid air meets cool wall surfaces. It’s a big deal in older Humble homes near the lake.
Can you insulate walls without tearing out drywall?
Yes, drill-and-fill and injection foam are both done through small access holes that we patch afterward. Most jobs are completed in a single visit with no drywall replacement needed.
Attic Cleaning & Rodent Proofing in Humble
Humble’s mix of older wood-frame homes, mature trees, and post-Harvey construction gaps makes attics attractive to rats, mice, and squirrels. Once rodents get in, they contaminate insulation with droppings and urine, chew wiring, and create a biohazard that affects indoor air quality. Cleaning and rodent proofing means removing the contaminated material, sanitizing the space, and sealing every entry point so they can’t get back in. Our Attic Cleaning & Rodent Proofing work is the first step before any new insulation goes in.
Attic Cleanout
Signs you need it
You hear scratching at night, see droppings near the attic hatch, or notice a smell that comes and goes with the AC. Rodents in Humble attics are common near mature tree lines and older neighborhoods.
What it costs in Humble
Attic cleanout in Humble typically runs $800-$2,500 depending on attic size and how much debris and contaminated material needs removing.
How we do it
We remove all contaminated insulation and debris, vacuum the attic deck, and dispose of everything in sealed bags.
Rodent Proofing & Exclusion
Signs you need it
Repeat rodent activity after trapping, or gaps around eaves, vents, and soffits. Sealing entry points is the only permanent fix.
What it costs in Humble
Rodent proofing and exclusion in Humble typically runs $600-$2,000 depending on how many entry points and linear feet of eave need sealing.
How we do it
We locate every entry point, seal them with galvanized mesh, foam, and flashing where needed, and verify the attic is fully closed before finishing.
What Attic Cleaning & Rodent Proofing Costs in Humble
| Item | Typical range in Humble |
|---|---|
| Attic cleanout | $800-$2,500 |
| Attic sanitizing & decontamination | $600-$1,800 |
| Rodent proofing & exclusion | $600-$2,000 |
| Attic restoration (full clean, sanitize, seal, reinsulate) | $2,500-$7,000 |
Do I need to replace insulation after rodents in my Humble attic?
Yes if the insulation shows droppings, urine stains, or nesting. Contaminated material can’t be cleaned effectively and needs to come out before new insulation goes in. The 5% Senior & Veteran discount applies to the whole job.
How fast can you clean and seal a Humble attic?
Most attic cleanouts and rodent proofing jobs are completed in a single visit, often within one day for an average home. Call (855) 657-3403 and a live person will schedule it.
Home Energy Audit in Humble
A home energy audit is the diagnostic starting point that makes every other insulation and air sealing job smarter. In Humble, where humidity and heat load vary house by house, guessing at the problem wastes money. We test the whole house, find where air and heat are actually moving, and give you a prioritized list of fixes. Our Home Energy Audit includes blower door testing, thermal imaging, and a full insulation and duct inspection, all with upfront pricing.
Blower Door Test
Signs you need it
High summer bills, drafts near baseboards, or rooms that never hold temperature. A blower door test quantifies how leaky your Humble home actually is.
What it costs in Humble
A standalone blower door test in Humble typically runs $250-$500 depending on home size and access.
How we do it
We mount a calibrated fan in an exterior door, depressurize the house, and measure the total air leakage in cubic feet per minute.
Thermal Imaging Inspection
Signs you need it
Inconsistent room temperatures, cold spots in winter, or you suspect missing insulation in walls. Thermal imaging shows exactly where the gaps are.
What it costs in Humble
Thermal imaging inspection in Humble typically runs $200-$450 when done as part of a full audit.
How we do it
We scan walls, ceilings, and floors with an infrared camera while the blower door runs, then map the temperature differences to locate missing or settled insulation.
What Home Energy Audit Costs in Humble
| Item | Typical range in Humble |
|---|---|
| Blower door test | $250-$500 |
| Thermal imaging inspection | $200-$450 |
| Insulation inspection | $150-$350 |
| Duct leakage test | $250-$550 |
Is a home energy audit worth it for an older Humble home?
Yes, especially for 1940s-1970s homes that may have no wall insulation and original air sealing. The audit tells you which fixes will pay back fastest, so you don’t spend money on the wrong thing first.
How long does a home energy audit take?
Most Humble audits run 2-4 hours depending on home size and how many systems we’re testing. You’ll get a written report with prioritized recommendations and pricing for each fix.

What Humble Customers Say
"They did the energy audit first - blower door and thermal camera - and showed me exactly where the house was leaking before selling me anything. The fix ended up being air sealing plus a modest attic top-up, not the full replacement another company pushed."
- Grace Nakamura"Solid work on the spray foam in the rim joists and the garage ceiling. Scheduling slipped a day because of rain, which they called about ahead of time. Would use them again."
- Tom Reinholt"Crawl space smelled musty and the floors were cold. Full encapsulation with the thick liner taped at every seam, and a dehumidifier sized for the space. The hygrometer they left reads 48 percent now instead of the 70s."
- Elena Vasquez
