How CertainTeed Products Fail – and How We Fix Them
CertainTeed makes solid insulation products. But in Houston attics, heat and humidity expose specific failure patterns we see on a regular basis. Here’s what we find and how we address it.
- InsulSafe SP settling. CertainTeed’s InsulSafe SP fiberglass blown in insulation settles over time, especially in Houston’s humid attics where the material absorbs moisture and compresses. A 20-year-old attic that started at R-38 is often sitting at R-22 or worse. We remove the compromised material, air seal the attic floor, and blow in fresh InsulSafe SP to a verified depth.
- TrueComfort blown in fiberglass uneven coverage. TrueComfort is designed for pneumatic installation, but rushed installs leave thin bands around attic hatches, soffits, and can lights. The fix is methodical: we map the attic, measure depth every 10 feet, and re-blow to consistent coverage before you pay a dime.
- Air leakage defeating the R-value. CertainTeed’s own literature states that blown in insulation performs best when air movement through the attic floor is controlled. In Meyerland, Bellaire, and West University slab homes, penetrations around plumbing stacks and electrical chases are common. We air seal first, then install the CertainTeed product. Insulation without air sealing is like a raincoat with the zipper open.
- Batt-to-blown conversions done wrong. Houston homes from the 1970s and 1980s often have compressed fiberglass batts that someone simply blew over, trapping gaps and moisture beneath. We remove the old material, inspect for rodent damage and moisture, and start clean with the right CertainTeed blown in product for the cavity depth.
- Wet or mold-compromised material. A roof leak or HVAC condensate drip in a Houston attic ruins blown in insulation fast. CertainTeed fiberglass doesn’t hold moisture the way cellulose does, but the facing and surrounding materials can still degrade. We identify the moisture source first, then remove and replace the damaged section.
One thing we see often: homeowners in Kingwood and The Woodlands who had blown in insulation added five years ago and saw no bill change because nobody air sealed the attic first. That’s not a product failure. It’s a process failure. We fix the process.
Our CertainTeed Blown In Insulation Process
Every job follows the same sequence. No shortcuts, no improvisation.
- 1
Call and schedule. You reach a live person at (806) 581-1010. We book a window that includes a real arrival time, not a four-hour guess.
- 2
Walkthrough and measurement. Our technician inspects the attic, measures square footage, checks current R-value, looks for air leaks, moisture, and any electrical or ventilation issues. We give you the written price at this point, before any work starts.
- 3
Prep and removal. If old insulation needs to come out, we remove it with commercial vacuums and bag it for disposal. We protect your living space with drop cloths and seal off the attic access.
- 4
Air sealing. We seal penetrations at the attic floor with foam or caulk where appropriate. This is the step that separates a good job from a wasted one.
- 5
Blown in installation. We install the CertainTeed product to the depth required for your target R-value, checking depth markers as we go. Coverage is verified before we leave.
- 6
Final inspection and documentation. We walk you through what we did, show you photos of the finished attic, and hand you the written guarantee. The 365-Day Done Right Promise means if it fails within a year, we return at no charge.
Total time for a typical 1,800-square-foot Houston home: five to seven hours from arrival to final walkthrough.
What CertainTeed Blown In Insulation Costs in Houston
Most CertainTeed blown in insulation projects in Houston fall between $1,800 and $4,200. The spread comes down to attic square footage, the R-value you’re targeting, and whether old material needs removal first.
| Scenario | Typical Range |
|---|---|
| Top-up over existing, 1,200 sq ft attic, R-30 to R-38 | $1,800 – $2,400 |
| Full removal and re-blow, 1,500 sq ft attic | $2,800 – $3,400 |
| Removal, air sealing, and new blown in, 2,000+ sq ft attic | $3,400 – $4,200 |
| Attic air sealing only, before insulation | $600 – $1,100 |
Removal of old, wet, or compacted material adds labor and disposal fees. Air sealing adds about 10 to 20 percent to the total but typically pays for itself within two Houston summers. Call (806) 581-1010 for an exact quote. The estimate is free and the number we give you before work starts is the number on your invoice.

FAQs
CertainTeed offers a limited lifetime warranty on many of its insulation products for the original homeowner, and we install to manufacturer specifications so your warranty stays intact. As an independent service provider, we don’t process warranty claims, but we’ll help you document the work properly.
In most cases, yes. We schedule within a few days of your call, and during slower months we can often get a crew out next day. Call (806) 581-1010 and we’ll give you a specific arrival window, not a range.
Topping up is cheaper up front, usually $1,800 to $2,400 for a typical Houston attic. But if the existing material is wet, compacted, or riddled with rodent droppings, removing it first is the only responsible move. We’ll tell you which applies after we see the attic, and the written estimate covers either path.
Fiberglass blown in insulation like CertainTeed InsulSafe SP can last the life of the home if the attic stays dry and air sealed. The bigger issue in Houston is settling and humidity, which can reduce effectiveness over 15 to 20 years. Regular attic checks catch it early.
In most Houston homes with less than R-30 in the attic, yes. The DOE recommends R-38 to R-60 for our climate zone. If you’re below that, added insulation typically pays for itself in three to five years. Air sealing first makes the difference bigger. Call (806) 581-1010 for a free estimate and we’ll measure your current R-value at no charge.
