Insulation Company in Katy, TX
Alden Attic Insulation is the insulation company Katy homeowners call when the attic stops doing its job. Katy’s humid subtropical summers push attic temperatures past 130°F, and most homes built in the 1990s and 2000s left the factory with R-30 fiberglass, the bare minimum code at the time. That combination means high cooling bills, uneven room temperatures, and moisture problems that show up as mold or warped drywall. We install and remove attic insulation, blown-in insulation, and do full removal work, with a written price before tools come off the truck. Call (806) 581-1010 for a free estimate.
Why Katy Homes Are Different
Katy’s housing stock tells the story of the city’s growth. Master-planned communities like Cinco Ranch, Firethorne, and Seven Meadows went up fast between the 1990s and 2010s, and many of those homes share the same problem: vented attics with blown fiberglass rated at R-30, which is not enough for Katy’s climate. The builders hit minimum code, the AC systems got sized for square footage rather than thermal reality, and the result is an attic that bakes all afternoon in July and August. That heat pushes down into the living space, and the AC runs longer than it should. Air leaks around recessed lights, attic hatches, and bathroom vent fans make it worse. Older sections of Katy, near the original town site off Highway Boulevard, have a different issue. Pier-and-beam homes sit above crawl spaces that hold humidity, and the floors get warm in summer because there is little insulation between the joists. Homes in neighborhoods like Nottingham Country and Memorial Parkway are old enough now that insulation has settled and compacted, which lowers its R-value below what the label says. The material is still there, but it is not trapping air the way it did when it was installed.
Our Main Katy Services
Three services cover nearly every insulation problem a Katy home can have. Each has its own page with full pricing and details.
Attic Insulation in Katy
Most Katy attics need more insulation than they have. We remove nothing for this job. We assess what is there, determine the current R-value, then install new insulation on top or replace it if it has failed. Local conditions matter: in Cinco Ranch, wind-washing along the eaves compresses the outer edges of fiberglass batts and cuts their effectiveness. That is why we inspect the full attic perimeter, not just the center. Read the full breakdown at Attic Insulation in Katy.

Blown In Insulation in Katy
Blown-in insulation gets into the irregular spaces that batts cannot. Katy attics with truss webs, cross-bracing, and recessed light housings benefit most from blown fiberglass or blown cellulose. The material flows around obstructions and creates a continuous layer without the gaps that batts leave behind. In homes with older recessed lights, we build dams around the fixtures so the material stays put without blocking airflow. Details and rates are on the Blown In Insulation in Katy page.

Insulation Removal in Katy
Removal becomes necessary when insulation has been soaked by a roof leak, infested by rodents, or contaminated by dust and mold. Katy’s humidity makes wet insulation worse than in dry climates: the moisture does not evaporate on its own, and the material loses its R-value fast. We remove everything down to the attic floor, sanitize the space, and take the old material away. The process and costs are covered at Insulation Removal in Katy.
