We’re Woolsey Insulation Houston, and we’ve spent years working on the specific problems Humble homes throw at insulation: pier-and-beam crawlspaces, humidity that never quits, and older ranch houses that were built when nobody thought about sealing air leaks. Led by Glenn Hartley, our crew knows what works here and what doesn’t. We don’t guess. We give you a written price, show up in the window we promised, and put a 365-day guarantee in writing on every job.
Why Woolsey Insulation Houston Is Humble’s Preferred Spray Foam Insulation Company
Three things matter to Humble homeowners, and they’re the three things we built our reputation on. First, we answer the phone. Not a call center, not a voicemail maze. A real person, 24 hours a day, seven days a week. Second, we price the job before we touch anything. You get a written number, and that’s the number, no matter what we find when we open the attic. Third, our technicians are background-checked and uniformed, so you know exactly who’s walking into your home on Beltway 8 or Will Clayton Parkway.
Glenn Hartley has run crews through every type of Humble housing stock there is: 1960s brick veneer ranches in Lakeland, 1980s wood-frame homes in Timberwood, and newer tract builds near Generation Park. He’ll tell you the same thing we tell every customer: the material matters less than the installer’s understanding of where air and moisture actually move in your specific house. That’s the difference between insulation that works for 20 years and insulation that fails in two.
We work with eight leading brands, including Knauf, Rockwool, and Icynene, so the foam we recommend fits your home’s construction, not whatever happens to be on the truck. Every job carries The Kingswell Guarantee: a written price before work starts, a committed arrival window, a clean job site, a written guarantee on the work, and a free return visit if anything fails within 365 days.
Spray Foam Insulation Contractors in Humble
Spray foam insulation contractors in Humble do more than spray foam. They diagnose why your house is uncomfortable, find where air and moisture are getting in, and recommend the right fix for your specific foundation type and attic configuration. On a pier-and-beam home east of US-59, that means addressing the crawlspace first; on a slab ranch near Deerbrook Mall, it usually means attic and rim joist work. A full attic spray foam job in Humble runs $2,400 – $4,800 for open-cell or $3,800 – $6,800 for closed-cell, depending on square footage and roof pitch. Rim joist sealing runs $900 – $1,800 for a typical 1,800 – 2,200 square foot home.
What the job actually involves
We inspect the attic, rim joists, and crawlspace (when you have one), then map where air is leaking and where moisture is collecting. On most Humble homes, the attic is the biggest offender: heat radiates through the roof deck, the A/C struggles, and condensation forms on ductwork. We air-seal first, then apply the foam. You’d be surprised how many “insulation” companies skip the air-sealing step entirely.
When Humble homeowners call us
Usually it’s one of three triggers: a room that won’t cool in August, a utility bill that jumped, or water stains on the ceiling after a heavy storm revealed a moisture problem in the attic. Sometimes it’s all three. We respond to Humble calls same-week in most cases, and same-day for emergency situations like a roof leak that’s soaked your existing insulation.
Spray Foam Attic Insulation in Humble
Spray foam attic insulation in Humble solves a problem that fiberglass batts simply can’t: air movement. Humble’s humidity stays above 80% most of the year, and when hot, humid air leaks into a vented attic, it condenses on ductwork and framing. Batts sit on top of the ceiling but don’t stop that airflow. Open-cell spray foam seals the attic against air infiltration and drops the attic temperature by 20 – 30 degrees in summer. Closed-cell goes further, adding structural strength and a moisture barrier. For most Humble attics, open-cell on the roof deck runs $2,400 – $4,200; closed-cell runs $3,400 – $6,800 for a typical 1,500 – 2,200 square foot attic.
Open-cell vs. closed-cell in a Humble attic
Open-cell foam is lighter, less expensive, and excellent for sound dampening. In a Humble attic with frequent condensation on ductwork, it stops the condensation by cutting off the humid air supply. Closed-cell foam adds an R-value of roughly 6.5 per inch versus open-cell’s 3.7 per inch, and it acts as a vapor retarder. For attics that have already shown mold or condensation damage, we often recommend closed-cell on the roof deck.
Attic retrofits on older Humble homes
Homes built in the 1960s through 1980s across Humble often have R-19 or R-30 batt insulation that’s settled, displaced by humidity, or simply inadequate for Gulf Coast heat. We remove the failed material, air-seal penetrations around recessed lights, ceiling fans, and attic hatches, then apply spray foam directly to the roof deck. The result is a conditioned attic that stops fighting your air conditioner.
Trusted Brands We Service in Humble
We install products from eight leading manufacturers, and on any given Humble job we usually recommend from a short list: Knauf for high-performance open-cell applications, Rockwool for fire-resistant perimeter sealing, and Icynene for closed-cell roof decks and crawlspaces. We’re not married to one brand. We’re married to getting your house right. Because we stock materials locally for Humble jobs, we can often start within a few days of your estimate. You get a written recommendation for the specific foam type and brand before we order anything, and that recommendation is based on your home’s construction, not our inventory.
Common Spray Foam Insulation Problems We See in Humble Homes
- DIY foam kits applied too thin in humid attics. Humble’s humidity above 80% means condensation forms on any surface that’s cooler than the dew point. A thin layer of DIY foam doesn’t stop the humid air, so ductwork still sweats, and within a season you’ll see streaks of mold along the foam face.
- Open-cell foam in pier-and-beam crawlspaces without a vapor barrier. In Timberwood and Lakeland, soil moisture migrates up through the crawlspace. Open-cell foam absorbs that moisture, loses R-value, and creates a damp environment that attracts termites and encourages wood rot.
- Post-storm repairs that skip the rim joist. After a heavy rain season east of US-59, we see homes where the attic got new foam but the rim joist was ignored. Air still leaks in around the floor perimeter, so upstairs rooms stay humid and the floors above the crawlspace stay warm.
- Fiberglass batts that wicked moisture and slumped. We’re called to older Humble ranches every spring for this. The batts in the crawlspace have fallen away from the floor joists after absorbing moisture from storm runoff, leaving the floor above noticeably warmer and the subfloor damp against the framing.

FAQs About Spray Foam Insulation in Humble
Yes, in most Timberwood pier-and-beam homes, warm floors come from failed or missing insulation in the crawlspace, and closed-cell spray foam applied to the underside of the floor system fixes it. The warm floors usually mean fiberglass batts have wicked moisture from soil or storm runoff and slumped away from the joists. We remove the failed batts, air-seal the rim joists, and apply closed-cell foam directly to the subfloor. The floor above stops absorbing heat from the crawlspace, and the room temperature evens out, often within a day or two. Call (903) 447-8369 and we’ll come look at your crawlspace.
Closed-cell foam is generally better for a Humble attic with condensation on ductwork because it acts as a moisture barrier and adds more R-value per inch. That said, open-cell foam properly applied to the roof deck seals the attic against humid outside air, which often stops the condensation entirely. The real issue is air infiltration: Humble’s 80%+ humidity means any air leak carries moisture into the attic. We’ll inspect your ductwork and roof deck, identify where the humid air is coming from, and recommend the foam type that fits your specific attic. Estimates are free, and the number we give you is the number you pay.
Most 1980s ranch homes in Humble were built with R-11 or R-13 wall insulation, which is below the R-15 to R-19 that current Gulf Coast standards recommend, so retrofits often make sense. We can do a visual inspection and an infrared scan of your walls to see where insulation is missing or has settled. If the walls are under-insulated, spray foam can be injected into the cavities, though most Humble homeowners see the biggest comfort gain from attic and rim joist sealing first. Call us and we’ll tell you honestly whether your walls are the problem or your attic is.
Yes, but only after the crawlspace has been properly dried and any contaminated materials have been removed, which is a common situation in Humble’s floodplain neighborhoods. Closed-cell spray foam is actually the best choice for a flood-prone crawlspace because it doesn’t absorb water the way fiberglass does. We’ll check for standing water, remove failed insulation and any mold-damaged material, and only apply foam to a dry substrate. If your crawlspace flooded recently, call us before you re-insulate: the order of operations matters, and we’ll walk you through it honestly.
With closed-cell spray foam at 2 inches or more applied to the underside of the floor system, you typically don’t need a separate vapor barrier on the ground, because the foam itself acts as a moisture barrier. With open-cell foam, you do need a vapor barrier, because open-cell absorbs moisture from soil and loses R-value. In Humble’s high-humidity climate and flood-prone clay soils, we almost always recommend closed-cell for crawlspaces and open-cell for attics. The exact recommendation depends on your foundation type and drainage, and we’ll put it in writing before any work starts.
