Owens Corning Attic Insulation: The Houston Owner’s Guide
If you’re looking for Owens Corning attic insulation in Houston, we stock and install the full Owens Corning product line, including ProPink blown-in fiberglass and R-38 and R-49 batt configurations, with typical installed pricing running $1.60 to $2.80 per square foot depending on your attic’s depth, access, and current insulation condition. Most Houston attics we see were built to R-19 or R-30 in the 1980s and 1990s, which leaves them roughly half as effective as what Owens Corning recommends for our climate zone. The usual way a homeowner discovers their Owens Corning insulation has failed is a hot spot in the ceiling, a room that won’t hold temperature, or an electric bill that climbs every July and never comes back down.
We are an independent insulation contractor in Houston and we are not affiliated with Owens Corning. We do, however, install their products every week and we know exactly how they perform in the Houston heat and humidity. Neil Barron, our owner, has walked enough attics from the Heights to Hermann Park to know that two homes built the same year can have completely different insulation conditions, and he’ll walk yours twice before he quotes anything. That’s just how we work.
Which Owens Corning Models This Applies To
Owens Corning makes three main attic insulation product types that matter to Houston homeowners: ProPink blown-in fiberglass (often labeled L77 or L88), EcoTouch batt insulation (available in R-19, R-30, R-38, and R-49), and the newer AttiCat expanding blown-in system. The ProPink loosefill and EcoTouch batts are the two we see most often in existing Houston attics, and they are not interchangeable in every situation. Batts work well in open, regularly spaced rafter bays. Blown-in handles the messy reality of older Houston homes where rafter spacing varies, framing is irregular, and there’s low-slope sections a batt simply cannot fill.
Here’s the compatibility gotcha most people don’t know: if your attic already has Owens Corning ProPink blown-in and has settled to R-19 levels, you can absolutely top it up with another layer of ProPink. But if you mix blown-in fiberglass over old batt insulation, you create gaps and compression that cut the effective R-value by up to 40 percent. We’ve measured it with thermal cameras in attics all over Houston. The fix is either removing the old batts first or sticking with a compatible loosefill. For batt replacements, Owens Corning EcoTouch comes in pre-cut widths of 15 and 23 inches, and the R-38 and R-49 versions are thicker than most people expect. Recessed lights, bathroom fans, and wiring all need to be addressed before batts go down, or you’re paying for insulation that can’t do its job. We stock ProPink loosefill and EcoTouch batts on our trucks, so most quotes turn into completed jobs the same week.
Signs Your Owens Corning Attic Insulation Is Failing
- Uncomfortable rooms directly under the attic. If the ceiling feels hot to the touch in summer or cold in winter, your insulation has likely settled, compressed, or been displaced. Fiberglass loses loft over time, especially in Houston’s humid climate, and once it loses loft it loses R-value quickly.
- Wild temperature swings between upstairs and downstairs. This usually means uneven distribution, gaps around the attic perimeter, or insufficient depth. Older Owens Corning batts often leave a 6 to 12 inch gap along exterior walls where heat pours in all day.
- Rising cooling bills with no change in your thermostat habits. Houston air conditioners run hardest in August. If your July and August bills keep climbing year over year while your upstairs stays warm, the insulation is likely the weakest link in the chain.
- Pest activity in the attic. Squirrels, rats, and raccoons will shred fiberglass to make nests, compact it into corners, and push it around. If you hear scratching overhead, there’s a good chance your insulation has been chewed, soiled, and compacted in spots.
- Signs of moisture or dark staining on the insulation. Houston’s humidity, a small roof leak, or improper bath-fan venting can saturate fiberglass, which kills its thermal performance and can lead to mold. Wet insulation has to come out. Adding more on top only hides the problem.
Replacement Cost & What’s Included
In Houston, a full Owens Corning attic insulation replacement typically runs between $1,800 and $4,200 for an average 1,500 to 2,000 square foot attic, depending on existing depth, access, and whether we’re adding or removing old material. A top-up over settled existing ProPink runs less, usually $1.60 to $2.20 per square foot, while a complete removal and replacement with R-38 or R-49 EcoTouch batts runs higher because of the labor to bag and haul out old insulation. Here’s how that breaks down in most local homes:
| Scope of Work | Typical Houston Price |
|---|---|
| Blown-in ProPink top-up over existing loosefill | $1.60 – $2.20 per sq ft |
| Full removal of old insulation + ProPink blown-in | $2.10 – $2.80 per sq ft |
| R-38 EcoTouch batt replacement (standard attic) | $2.30 – $3.10 per sq ft |
| R-49 EcoTouch batt replacement (deep rafter bays) | $2.60 – $3.40 per sq ft |
Every quote includes labor, materials, cleanup, and disposal. And here’s the part that matters most to us: you get a written price before any work starts. Not a range, not a guess, not a “we’ll see how it goes.” Neil walks the attic twice, puts the number in writing, and that’s the number you pay. Every job is covered by our 365-Day Done Right Promise. If it’s not right, we make it right. No debate, no fine print.
DIY or Call Us?
Blown-in fiberglass and batts are not dangerous to handle in the way garage door springs or electrical panels are. The real danger in a Houston attic is the attic itself: 130 to 150 degree heat in late summer, truss nails at head height, low-hanging wiring, and brittle decking that can crack underfoot. If you want to peek up there, check for obvious gaps, moisture stains, or pest droppings, and don’t go more than a few feet from the access hatch. Full insulation work requires proper respirators, protective suits, and a clear plan for moving around safely while carrying material. We send background-checked, uniformed technicians into your home, and they lay drop cloths across your hallway and put shoe covers on at the front door before anyone opens the attic hatch. It’s a service we built from the ground up, and it’s included every single time.
If you’d rather not spend an hour in a 140 degree attic, call us at (430) 226-1334 and we’ll send someone out. Estimates are free.
FAQs
Owens Corning fiberglass insulation, both ProPink loosefill and EcoTouch batts, typically lasts 30 to 50 years in a dry, undisturbed attic. In Houston, the real enemy is humidity and animal activity, which can cut the effective lifespan to 15 or 20 years in homes with poor ventilation or recurring pest issues. Call (430) 226-1334 and we’ll tell you exactly what condition your insulation is in, free.
In many cases, yes, a top-up of ProPink loosefill over settled or compacted fiberglass is a cost-effective fix that doesn’t require full removal. If the insulation is wet, moldy, or heavily contaminated by animal waste, removal and replacement is the only correct approach. We’ll give you an honest assessment either way, and you won’t pay for work you don’t need.
Most full attic insulation replacements in Houston take one day for the insulation work itself. If we’re removing old material, bagging it, and disposing of it, expect the crew to be on-site for 6 to 8 hours. A simple blown-in top-up usually wraps up in 3 to 4 hours, and we leave a photo of the cleanup before the van pulls away.
We stock ProPink blown-in fiberglass and EcoTouch batt insulation on our trucks, including the R-38 and R-49 options most Houston attics need. We also carry Reflectix radiant barrier products for homes where attic heat gain is a specific concern. If we need a particular Owens Corning product for your attic, we’ll have it in hand before the scheduled install date.
Tell me what’s in the room on the other side of that wall, and I’ll tell you exactly what goes between it. That’s how we price every Owens Corning attic insulation job in Houston, and it’s why we put the exact material spec and the exact number in writing before anyone picks up a tool.
