Insulation Company in Houston, TX
Thistledown Insulation Houston installs attic and spray foam insulation in Houston, TX, with a written price before any work starts. Houston homes fight humidity and heat year-round, and most were built for air conditioning, not cold weather – so insulation here has to control moisture as much as temperature. Neil Barron and our crews work in attics across Houston every week, pairing insulation with air sealing so cooling dollars stop leaking through ceilings. Call (430) 226-1334 for a free estimate.
Why Houston Homes Are Different
In Houston, insulation work is defined by the fight against extreme humidity and heat. Many homes from the 1960s through the 1980s have low-pitch roofs, brick veneer, and what was considered adequate insulation at the time – which today means inefficient. Newer suburban developments often aren’t much better, since historically lax energy codes let builders leave attics with minimal coverage. Radiant barriers matter here more than in most of the country, because beating back attic heat gain is half the cooling battle.
Older neighborhoods tell the story clearly. In Sharpstown and Meyerland, blown-in fiberglass often settles or gets matted down by humid air leaking from the living space. From the attic hatch, the insulation looks fine. But down at the ceiling line, it’s performing like a thin blanket instead of a real barrier. Houston’s clay-heavy soil also shifts with wet-dry cycles, which means small gaps open around exterior walls over time. Air sealing matters as much as the insulation itself.
Our Main Houston Services
Most Houston homeowners call us about two services: attic insulation and spray foam insulation. Each has its own dedicated Houston page with pricing and full details.
Attic Insulation in Houston
Attic insulation in Houston usually means removing old, matted fiberglass or topping it with fresh blown-in material. In older neighborhoods like Sharpstown and Meyerland, humidity from the living space wets the existing insulation over the years, and it compresses. We check what’s actually happening at the attic floor before recommending anything. We stock Rockwool and CertainTeed products, among others, and we match the material to your attic’s ventilation and your family’s needs. Learn more on our Attic Insulation in Houston page.
Spray Foam Insulation in Houston
Spray foam insulation in Houston works differently: it seals and insulates in one step. That matters here because humid air sneaking through ceiling penetrations is what causes so much attic mold and condensation. Closed-cell foam also helps with roof deck performance during hurricane-season rains. We install Icynene and Demilec systems, and we wear shoe covers and lay drop cloths from the front door to the attic hatch on every job. Learn more on our Spray Foam Insulation in Houston page.
