Insulation Company in Houston, TX
Most Houston homes are fighting a losing battle against heat and humidity, and the attic is where that battle is decided. Homes built during the 1970s and 1980s boom often have R-19 or less up top, much of it settled, displaced, or simply gone. At Woolsey Insulation Houston, we install and service attic insulation and spray foam insulation for homeowners across the city, and our work starts with a written price before any work begins. Call (903) 447-8369 and a live person answers, 24/7.
Why Houston Homes Are Different
Houston’s hot, humid subtropical climate means insulation has to do two jobs at once: block the heat and manage moisture. High humidity can cause fiberglass to lose R-value when damp, and poor air sealing can lead to condensation and mold in attics. The long cooling season, April through October, makes attic insulation the single most impactful energy upgrade for most homes here.
The housing stock adds another layer. Houston’s lack of zoning has created blocks where a 1950s bungalow sits next to a 2000s tract home. That patchwork means contractors regularly encounter different framing spacing, different roof pitches, and wildly different existing insulation depths from one job to the next. In older neighborhoods like Braeswood or Sharpstown, original blown-in insulation has often compacted to under 4 inches, and raccoons or squirrels have tunneled through it, leaving bare spots directly above the master bedroom. The AC runs nonstop in August but the room won’t cool below 78°F. We see that pattern constantly.
Low-slope roofs and minimal soffit ventilation are common in the 1970s and 1980s housing stock, and Harris County’s code amendments add compliance considerations that don’t show up in every market. None of this makes the work impossible, but it does mean the person assessing the attic needs to know Houston specifically.
Our Main Houston Services
Two services cover the large majority of what Houston homeowners ask us about. Each has full detail on its own page.
Attic Insulation in Houston
Attic insulation in Houston means dealing with whatever is already up there, and what’s already up there is usually inadequate. We find settled fiberglass, rodent-damaged batts, and attic floors with bare patches where R-value has effectively dropped to zero. The work involves assessing existing depth, air sealing where needed, and installing material that holds up in Houston’s humidity. Older neighborhoods like Sharpstown and Braeswood have some of the most compacted insulation we encounter anywhere. Learn more on the dedicated Attic Insulation in Houston page.
Spray Foam Insulation in Houston
Spray foam insulation, a two-part liquid that expands on contact and seals gaps airtight, is a strong fit for Houston’s climate because it addresses heat gain and air movement together. In older homes with irregular framing spacing or hard-to-reach attic cavities, it fills gaps that batts can’t. The humidity here makes air sealing especially important: when conditioned air leaks into a hot attic, condensation follows.

What Houston Customers Say
"The guy didn't try to sell me on foaming the whole house. He said the attic was where I'd actually feel it and left it at that. Honest, and he was right, our bills dropped."
- Angela Ruiz"Spray foam in the crawlspace and new attic insulation. They wrote up the whole price and the two jobs came in exactly as quoted. Floors upstairs aren't freezing in the morning anymore."
- Nathan Pruitt"Upstairs was always ten degrees hotter than downstairs in summer. They added attic insulation and the difference is night and day. Written price up front, no add ons at the end."
