Alden Insulation Houston serves South Houston with attic insulation, blown-in insulation, and insulation removal, and we answer the phone 24/7 at (806) 581-1010.

Why Alden Insulation Houston Is South Houston’s Preferred Attic Insulation Team
South Houston homeowners call us because we show up inside the scheduled window, not a vague half-day range. Every technician is background-checked and in uniform, so you know who’s walking through your door. We’re part of the Garrison Partners family, established 2002, and every job follows The Garrison Standard: written prices, written guarantees, and a crew held accountable for the work. That matters in a city where many homes are 1950s-70s ranches with original insulation that’s long past its useful life.
Our Attic Insulation crews work in South Houston regularly, from South Houston Gardens to neighborhoods off Allen-Genoa Road. Homeowners here tell us they’ve been burned before by contractors who quoted low and revised at the door. We don’t do that. The number you approve is the number on the invoice. And if the work fails within 365 days, we come back at no charge. That’s the Done Right Promise, and it’s on paper for every single job we do in South Houston.
Attic Insulation Removal in South Houston
Attic Insulation Removal in South Houston usually runs $1.50 – $2.50 per square foot, which for a typical 1,200-square-foot attic lands between $1,800 and $3,000. The job involves pulling out old, settled, or contaminated insulation, air sealing penetrations, and preparing the attic for new material. South Houston homeowners need this when original cellulose or fiberglass has compacted to R-11 or less, when humidity has caused mold or sagging, or when rodent activity has fouled the existing insulation. Removal also clears the way for rim joist air sealing, which is essential in this city’s pier-and-beam homes.
Signs Your South Houston Attic Needs Removal
If your AC runs nonstop in August and certain bedrooms stay hot, settled insulation is often the culprit. We inspect for moisture staining, compacted batts, and fiberglass that crumbles when touched, all of which signal it’s time to remove and replace.
Removal and Replacement in One Trip
Our crews run heavy-duty trucks with long hose reels, so we can remove old material and blow in new insulation the same day. No scheduling a second crew. No leaving your attic open for a week. One trip, done right, with a written guarantee on the result.
Insulation Contractors in South Houston
Insulation Contractors in South Houston aren’t all the same, and the differences show up in the details. We’re the insulation specialists of the Garrison Partners family, and we’re held to The Garrison Code on every job in South Houston: written price first, background-checked crew, uniformed technicians, and a written 365-day guarantee. What does a contractor actually do here? We assess your current R-value, check ventilation, inspect rim joists, and recommend the insulation type that fits South Houston’s heat and humidity. Then we do the work and stand behind it in writing.
What We Check Before Quoting
Before we hand you a written price, we look at attic depth, existing insulation condition, ventilation baffles, and whether your pier-and-beam foundation has uninsulated rim joists. That last one is the South Houston difference, and it’s why attic-only work often disappoints. We quote the whole job, not just the attic.
Written Price, No Door-Revisions
The price we hand you before work starts is the price you pay. No add-ons at the invoice. This is The Garrison Standard, and it’s how we’ve operated since 2002. If the work fails within a year, we return free. Full stop.
Trusted Brands We Service in South Houston
We install and service insulation from Owens Corning, CertainTeed, Icynene, Demilec, and GreenFiber, among others. That means you can research the material going into your attic before you say yes. For South Houston’s humidity, we often recommend Owens Corning AttiCat blown-in fiberglass or Demilec closed-cell spray foam where air sealing matters most. We stock materials locally for South Houston jobs, so turnaround stays fast. Bryce Holloway, who leads Alden Insulation Houston, insists on named brands with published specs because homeowners deserve to know exactly what they’re buying.
Common Attic Insulation Problems We See in South Houston Homes
- Humidity-driven settling: South Houston’s 90%+ humidity causes blown-in cellulose to sag to R-11 or less within a decade, leaving hot spots over bedrooms. We see this constantly in 1950s-70s ranches.
- Fiberglass breakdown at high heat: Attics here can exceed 140°F in summer, which breaks down old fiberglass batts and releases irritating fibers into the living space. Removal and replacement resolves it.
- Uninsulated rim joists: Nearly every pier-and-beam home in South Houston has uninsulated rim joists, a hidden thermal bypass that makes attic insulation alone ineffective. Air sealing the crawlspace rim joists is part of the real fix.
- Shallow attics with limited access: Many South Houston ranches and bungalows have tight attic access and shallow rafter bays, which is why blown-in insulation and experienced crews matter more than DIY attempts.

FAQs About Attic Insulation in South Houston
South Houston’s 90%+ humidity and 140°F+ attic temperatures cause blown-in cellulose to absorb moisture and compact to R-11 or less within ten years, while fiberglass batts break down under the heat. The fix is removal, air sealing, and a moisture-resistant blown-in product. Call (806) 581-1010 for an inspection, and we’ll tell you what’s actually in your attic.
Yes. Pier-and-beam homes have uninsulated rim joists that leak cooled air year-round, so attic insulation alone won’t solve your comfort or energy problems. We air seal rim joists from the crawlspace before or during the attic work. Every quote includes this assessment.
Yes. Our crews bring heavy-duty removal equipment and long hose reels to South Houston, so we pull old insulation, air seal, and blow in new material the same day. Most complete removals and replacements finish in one trip. Call (806) 581-1010 to schedule.
If certain rooms stay hot while the AC runs nonstop, or if you can see rafter lines poking through thin insulation, it’s likely below R-11. We measure the actual depth and material condition during a free estimate. You’ll get a written number for what’s there and what you need.
For most South Houston homes, we recommend Owens Corning AttiCat blown-in fiberglass or Demilec closed-cell spray foam where air sealing matters most. Both handle humidity better than settled cellulose, and both are brands you can research on your own before committing. We’ll show you the specs and let you decide.
