Trusted Blown In Insulation for Houston Homeowners
Houston attics punish under-insulated homes. Summer heat pushes attic temperatures past 140 degrees, and a thin layer of old insulation lets that heat bleed straight into your living space. Our Blown In Insulation in Houston typically runs $1.50 to $3.50 per square foot installed, with most attics landing between $1,800 and $4,200 depending on square footage and current R-value. Alden Insulation Houston has installed blown in insulation across Houston since 2002 as part of the Garrison Partners family, and we answer the phone at (806) 581-1010 with a live person, 24/7. Bryce Holloway leads our Houston crew, and every job gets a written price before work starts and a written guarantee that holds for 365 days.
Cellulose Insulation
Cellulose insulation is shredded, treated paper fiber blown into attic floors and wall cavities, and it’s a common choice for Houston homeowners who want dense, effective coverage with strong sound-dampening. It settles into gaps and around framing better than batts, and the borate treatment resists pests and flame. Alden Insulation Houston installs cellulose insulation from GreenFiber and CertainTeed, and most cellulose attic jobs in Houston run $1.50 to $2.80 per square foot depending on depth and existing material. If your attic has uneven coverage or old compressed material, blowing cellulose on top is often the fastest path to a consistent R-value.
Dense Coverage Without Tearing Out Drywall
Loose cellulose reaches corners and odd cavities that rigid batts miss. That matters in older Houston homes where framing spacing is rarely uniform. We blow to the depth required for your target R-value, checking coverage as we go.
Moisture And Pest Resistance That Fits Houston
Houston humidity is relentless. Treated cellulose holds its own against mold and insects, and we explain exactly which treatment is in the product we install. You’ll know the brand before it goes in.
Blown In Attic Insulation
Blown in attic insulation is loose material pneumatically applied across your attic floor to create a continuous thermal barrier, and it’s the most common upgrade we perform in Houston. Most Houston attics have R-19 to R-30 when they should be at R-38 to R-49 for our climate zone. Alden Insulation Houston blows attic insulation over existing material after checking for air leaks and verifying that venting still works. Attic-only jobs in Houston typically run $1,200 to $3,800 depending on attic square footage and current depth. We won’t add material over a problem, and we tell you if removal is needed first.
Raising R-Value In Older Houston Homes
Homes built before 1990 in neighborhoods like Spring Branch and Sharpstown often sit well below modern R-value targets. We measure what’s there, then calculate exactly how much new material it takes to hit your goal. No guesswork on the invoice.
Air Sealing Done Before We Blow
Insulation without air sealing still leaks. We check for gaps around can lights, plumbing penetrations, and top plates before material goes down. Sealing first makes every dollar of insulation work harder.
Blown In Cellulose Insulation
Blown in cellulose insulation is the same treated-paper product installed loose by machine, and it’s a strong fit for Houston attics where existing coverage is thin or uneven. The material packs well, covers framing, and reduces airflow through the attic floor better than fiberglass in side-by-side comparisons. Alden Insulation Houston blows cellulose from GreenFiber, and typical Houston projects run $1.50 to $2.80 per square foot installed. The final depth depends on whether you’re topping off old material or starting clean, and we always show you the target R-value before the machine starts.
Top-Off Jobs Over Existing Insulation
If your current material is dry and intact, we can often blow cellulose right over it. That saves removal cost and gets the attic to R-38 or better in a single visit. We confirm the existing layer is sound before recommending this route.
Fire-Treated Paper That Packs Dense
Modern cellulose carries a Class 1 fire rating from its borate treatment. That’s a fact worth knowing when you’re comparing materials. We’ll show you the manufacturer data sheet for the exact product we quote.
Blown In Fiberglass Insulation
Blown in fiberglass insulation is loose glass-fiber material applied with a blower, and it’s a popular Houston option because it holds its R-value without settling as much as older cellulose blends. Fiberglass also won’t absorb moisture, which matters in Houston’s humid months. Alden Insulation Houston installs blown fiberglass from Knauf and CertainTeed, and typical Houston attics run $1.40 to $3.20 per square foot installed. Like all our Blown In Insulation in South Houston work, the price is written down before the hose comes off the truck.
Low-Dust Blowing For Finished Attics
Fiberglass blows fast and covers large attics efficiently. If you use your attic for storage, we keep the area clean with drop cloths and a post-job sweep. Uniformed, background-checked techs handle the full job.
Consistent R-Value That Won’t Settle Much
Fiberglass holds its loft over time, which means the R-value we install is the R-value you keep. That’s a measurable difference. We document the installed depth and verify coverage with gauge checks during the job.
Loose Fill Insulation
Loose fill insulation is any thermally resistant material applied loose rather than in batts, and the term covers both cellulose and fiberglass blown through a hose. It’s the most practical way to insulate an attic in Houston without tearing out drywall or rebuilding framing. Alden Insulation Houston offers loose fill insulation in both material types, and standard Houston attic work runs $1.40 to $3.50 per square foot. The right material for your home depends on your current insulation, your attic access, and your budget, and we lay out the options in plain language before you approve anything.
Installed To Match Your Climate Zone
Houston sits in climate zone 2, which calls for R-38 to R-49 in the attic per current building code. We calculate depth from the material’s stated R-per-inch rating and verify it during install. You’ll see the numbers.
Clean Removal And Reinstall When Needed
If old insulation is water-damaged, pest-infested, or compressed beyond use, we remove it first and start fresh. Removal is part of what Alden does, and the written quote covers it line by line. No hidden line items at invoice.
Blown In Insulation Contractors
Blown in insulation contractors handle the machine, the material, and the installation knowledge, and the best ones in Houston give you a written price and a written guarantee before touching your attic. That’s the Garrison Standard at Alden Insulation Houston. We’ve operated in Houston since 2002 as part of the Garrison Partners family, and every technician who steps into your home is background-checked and in uniform. Pricing for contractor-installed blown in insulation in Houston runs $1.40 to $3.50 per square foot, which includes the material, the labor, and the clean-up afterward. A good contractor also checks your venting and air sealing, not just the fluff.
What Separates A Disciplined Insulation Crew
Written pricing, a 365-day guarantee, and a live person answering the phone at 7 p.m. or 7 a.m. Those aren’t extras, they’re the baseline at Alden. If the work fails within a year, we come back free.
Background Checks And Uniforms Matter In Your Home
You should know who is in your attic. Our crews are background-checked and arrive in uniform inside the scheduled window. That’s non-negotiable at every Alden location, including Houston.
Brands We Service
We install blown in insulation products from Knauf, CertainTeed, and Rockwool, along with five other industry brands homeowners can research independently. With Knauf fiberglass, we’ve handled countless Houston attic top-offs where the existing material had settled below spec; their fiberglass holds loft well in humid conditions. CertainTeed products give Houston homeowners a recognizable name with documented fire and moisture performance data, and we provide the manufacturer spec sheets on request.
Rockwool stone wool goes into specific Houston jobs where fire resistance and sound control are non-negotiable, and we’ve installed it in attached garages and shared-wall townhomes around the city. Whether you have a preference for one of these brands or any other make, Alden Insulation Houston can help you evaluate it honestly, because our guarantee covers the installation regardless of which material you choose.
Signs You Need a Pro Right Now
- Upstairs rooms run 8-10 degrees hotter than downstairs. That gap means heat is pouring through your attic floor. A pro can measure the temperature difference and check the R-value before recommending a fix.
- You can see the tops of your ceiling joists in the attic. If joists are visible above the insulation, your attic is under-insulated. Houston homes need enough depth to fully cover the framing, typically 12-16 inches depending on material.
- Energy bills spiked this summer without a change in usage. Air conditioners in Houston work harder when attic heat bleeds inward. Comparing July and August bills year over year can reveal the insulation’s decline.
- The insulation feels damp, matted, or smells musty. Houston humidity finds every roof leak and condensation point. Wet insulation loses its R-value fast and can grow mold against your ceiling drywall.
- You found rodent droppings or nesting material in the attic. Pests compress insulation and strip R-value wherever they nest. A pro can assess the damage and tell you whether removal, sanitizing, and reinstall is worth doing.
Our Process, Step by Step
- 1
Measure and assess the attic. We check current insulation depth, R-value, access clearance, venting, and signs of moisture or pests. The assessment is free and comes with a written quote before anything else happens.
- 2
Air seal if needed. We identify gaps around can lights, top plates, and plumbing stacks that let conditioned air escape. Sealing those first makes the new insulation materially more effective.
- 3
Confirm material and target depth with you. You’ll know which brand, which material type, and what R-value we’re installing. We show you the manufacturer data and the math on depth versus R-per-inch.
- 4
Blow the insulation to spec. Our crew runs the machine while checking depth gauges as they go. Coverage is verified before we pack up, and we document the finished depth with photos.
- 5
Clean up and walk through. We leave the attic and any access areas cleaner than we found them. You’ll get a recap of what was installed, at what depth, and the written 365-day guarantee that covers it.
How Much Does Blown In Insulation Cost in Houston?
Typical Blown In Insulation pricing in Houston runs $1,800 to $4,200 for a standard attic, with per-square-foot pricing between $1.40 and $3.50 depending on the material and current conditions. For a 1,500-square-foot attic with little or no existing insulation, expect the upper end. A simple top-off over existing material often lands closer to the $1,200 to $2,200 mark. Removal and disposal of old insulation adds cost, and we quote it as a separate line item so you can see exactly what you’re paying for.
What moves the price: attic square footage, current R-value, accessibility, whether removal is required, and whether air sealing work is needed first. What doesn’t move the price at Alden: the number we write down is the number you pay, and we never revise it at the door. Every free estimate from Alden Insulation Houston includes the material brand, the target R-value, and the labor, all in writing. To avoid overpaying, get at least two quotes, but compare what’s actually included, because a low quote without air sealing or cleanup will cost more in the long run.

Frequently Asked Questions About Blown In Insulation in Houston
Blown in insulation is loose material, either cellulose or fiberglass, that gets pneumatically sprayed across your attic floor or into wall cavities to create a thermal barrier.

Alden Insulation Houston installs both types and explains the difference before you commit.
Most Houston attic installations take four to six hours from setup to final cleanup. Larger attics or jobs that include removal can stretch into a second day. We schedule a specific window and show up inside it, not a vague half-day range.
