We’re Alden Attic Insulation, part of the Garrison Partners family since 2002, and we answer the phone with a live person around the clock at (806) 581-1010.

Why Alden Insulation Houston Is Katy’s Preferred Blown In Insulation Company
Katy homeowners call us because the job gets done in one trip and the price doesn’t move at the door. We’ve worked on hundreds of attics across Katy’s master-planned communities and older neighborhoods, and our technicians know the difference between a 1990s brick veneer home with wind-washed batts and a 2010s Cinco Ranch build that needs foam sealing at the top plates. That local knowledge means we bring the right material and the right approach the first time, not after a second guess.
Every Katy job is covered by the 365-Day Done Right Promise, written on paper. If the insulation fails within a year, we come back at no charge. That’s the Garrison Standard, applied by Bryce Holloway and his crew on every visit. Our technicians are background-checked and arrive in uniform, so when you open the door in Katy, you know exactly who’s walking in.
We coordinate dispatch from our Houston office, and Katy is a core service area for us, not an afterthought. Response time to most Katy neighborhoods is same-day or next-morning. You call, a person answers, and we schedule a real window. Not a half-day range.
Blown In Attic Insulation in Katy
Blown In Attic Insulation in Katy is the most common upgrade we install, and for good reason: Katy’s humid subtropical climate pushes attic temperatures past 140°F in July and August, and most 1990s-2010s homes were built to minimum code around R-30. That’s not enough here. We blow loose-fill fiberglass or cellulose across the attic floor to R-38, R-49, or R-60, depending on your home’s construction. A typical Katy attic between 1,500 and 2,200 square feet runs $1,500 to $3,400 for full coverage, including air sealing at top plates, wire penetrations, and any baffles needed around soffit vents.
Air Sealing Before the Blow
We don’t blow insulation over leaks. In Katy’s vented attics, air moves through every gap around recessed lights, plumbing penetrations, and top plates. We seal those first with foam, then blow to depth. Skipping that step is how you get an R-49 attic that still behaves like R-19.
Radiant Barrier for Katy Summers
For homes where the upstairs runs hot no matter the thermostat setting, we add a radiant barrier under the roof deck before blowing insulation. This reflects radiant heat back out before it ever reaches the attic floor. In Katy’s 90-plus-degree summers, that combination routinely cuts cooling load enough that oversized AC units finally cycle properly instead of running constantly.
Blown In Cellulose Insulation in Katy
Blown In Cellulose Insulation in Katy gives you dense coverage that batt insulation can’t match, and it’s our go-to for retrofitting older attics with irregular joist spacing. Cellulose is ground recycled paper treated with borate for fire and pest resistance, blown to settle into every cavity. In Katy homes from the 1990s and earlier, where fiberglass batts have shifted, compressed, or been walked down over decades, cellulose restores the R-value in one pass. Expect $1.80 to $2.80 per square foot installed, with a typical 1,800-square-foot attic landing between $2,200 and $3,900 depending on target R-value.
Crawl Space and Rim Joist Work
In Katy’s original town-site homes with pier-and-beam foundations, we blow cellulose into floor cavities only after sealing the rim joists and controlling ground moisture. Blowing cellulose into a vented crawl space without sealing first is a mold invitation. We do it in the right order or not at all.
One-Trip Depth and Density
We run density checks as we blow. A fluffed, shallow cellulose job settles fast and loses R-value within two years. In Katy’s high humidity, settled cellulose also loses its air-sealing performance. We blow to manufacturer spec and document the final depth in inches before we leave.
Trusted Brands We Service in Katy
We install and service blown-in insulation using materials from Knauf, Rockwool, and CertainTeed, plus cellulose from GreenFiber. You can look these brands up before you commit, and we’ll tell you exactly which one we’re installing and why it fits your Katy home’s construction. For bigger Cinco Ranch attics with high ceilings, we often spec Knauf or CertainTeed fiberglass for fast, even coverage. For older town-site pier-and-beam homes, Rockwool’s moisture resistance makes it a strong pick for floor cavities. Need a service call on existing blown-in material? We handle removal, top-offs, and full replacements across Katy.
Common Blown In Insulation Problems We See in Katy Homes
- Fiberglass blown over recessed can lights without baffles. The insulation settles, the light fixture becomes a glowing hole, and thermal cameras read 140°F at the ceiling. That heat pulls straight into your living space, and your AC fights it all summer.
- Cellulose in pier-and-beam crawl spaces without rim joist sealing. Humid Gulf air moves through the crawl space, the cellulose absorbs moisture, and mold appears behind baseboards in original Katy town-site houses. We seal first, blow second, verify third.
- Insulation covering soffit vents. Contractors blow over the vents in vented attics, airflow stops, and humid Katy air condenses on the roof sheathing. By late summer, plywood starts delaminating. We install baffles before blowing, every time, no exceptions.
- R-30 batts with wind-washing at the eaves. In Katy’s 1990s brick-and-stone veneer homes, poorly sealed soffit vents let wind scour the attic floor at the perimeter. The center of the attic looks insulated. The edges where it matters are bare. We see this constantly in Cinco Ranch and Firethorne.

FAQs About Blown In Insulation in Katy
R-60 is the target we recommend for 2010s Katy homes with oversized AC units, because deeper insulation plus air sealing lets the system actually cycle off instead of running constantly. Most Cinco Ranch and Firethorne homes start around R-30, so we’re typically doubling the depth. Call (806) 581-1010 for a free attic assessment and a written quote.
Only if the rim joists are sealed and ground moisture is controlled first. We blow cellulose into pier-and-beam floor cavities in original Katy town-site homes after sealing the rim joists with closed-cell foam and, where needed, laying a vapor barrier on the crawl space floor. Skipping those steps is how mold problems start. Call us and we’ll inspect the crawl space before recommending anything.
Usually not by itself. High humidity upstairs in Katy homes comes from air moving between the attic and living space, not just thin insulation. You need air sealing at top plates and penetrations, plus blown-in insulation to R-49 or R-60, and often a radiant barrier. That’s the full fix we’ve applied in hundreds of Katy attics. Call (806) 581-1010 and we’ll walk you through what your house actually needs.
We install baffles at every soffit vent before blowing any material, every single time. Baffles keep a clear air channel from the soffit to the ridge vent, so your attic keeps breathing and humid Katy air doesn’t condense on the roof sheathing. It’s standard practice on every Alden job in Katy, not an add-on.
Katy’s specific combination of high humidity and wide temperature swings causes loose-fill fiberglass and cellulose to settle faster here than in drier parts of the metro, especially when blown at low density. We compensate by blowing to manufacturer-specified density and documenting final depth in inches, so the R-value you pay for is the R-value that stays. Call (806) 581-1010 for an exact quote on your Katy attic.
