Owens Corning Blown In Insulation in Fresno: What to Know First
We install, top up, and remove Owens Corning blown in insulation throughout Fresno, and most jobs run $1,200 to $3,800 depending on square footage, current R-value, and whether old insulation needs to come out first. A typical attic top-up takes one day from start to cleanup. You’ll have a written price in your hand before a single tool comes off the truck, because that’s how Alden works.
This page is for homeowners who already have Owens Corning products in their attic or are considering them. If your attic feels like a kiln by 10 a.m. in July, or your upstairs rooms won’t hold temperature, you’re in the right place. Call (559) 666-2260 and you’ll get a live person, not a voicemail.
How Owens Corning Products Fail – and How We Fix Them
Owens Corning makes decent insulation. Pink fiberglass, AttiCat blown-in system, ProPink blown-in wall insulation, and their newer unbonded loosefill. But every product line has predictable failure points, and after years of crawling Fresno attics, we know exactly where to look.
- AttiCat settled coverage in older Fresno homes. Homes built before 2000 around the Tower District and Sunnyside often got a thin initial blow. Twenty-plus years of Central Valley heat cycling compresses AttiCat by 15 to 20 percent. Your R-38 attic is now acting like R-25. Fix: we measure depth in multiple spots, calculate actual R-value, then top up to code using fresh Owens Corning loosefill or a comparable R-value product.
- ProPink blown-in wall insulation with voids behind netting. We see this in 1980s-era houses off Blackstone and McKinley. The original installer blew too fast, didn’t let the fiberglass settle into corners, or used netting that sagged. Result: cold stripes on interior walls in winter, hot stripes in summer. Fix: we can dense-pack or remove and re-blow to consistent density. You can’t see the void from outside, but a thermal check and a borescope inspection show us exactly where the gaps are.
- Unbonded loosefill that migrated away from knee walls. Owens Corning unbonded fiberglass is light, which makes it easy to blow, but in attics with active gable vents or a powerful whole-house fan, loose fibers drift. We’ve opened attics in Clovis and northeast Fresno where the insulation had piled against one eave and left bare sheetrock near the other. Fix: add baffles, air-seal the gaps, and re-level the coverage. The R-value on the bag means nothing if the material isn’t where it’s supposed to be.
- Air sealing failures under Owens Corning fiberglass. This is the one the manufacturer’s website won’t tell you. Fiberglass filters air; it doesn’t stop it. If nobody sealed the top plates, can light housings, and plumbing penetrations before the pink stuff went down, your attic is filtering hot dusty air through the insulation. We see this constantly in Fresno, where summer attic temps hit 140-plus degrees. Fix: we pull back the existing Owens Corning insulation, seal every penetration with foam and caulk, then re-blow to the right depth. This is the difference between an attic that looks insulated and one that actually is.
- Rodent and pest damage in Owens Corning batts and blown material. Rats love fiberglass for nesting. In Fresno’s older neighborhoods, especially near mature trees and alleys, we find pink insulation matted down with droppings and urine staining. Owens Corning doesn’t claim rodent resistance, and neither should anyone else. Fix: we remove all compromised material, sanitize, seal entry points, and re-insulate. If your attic smells bad and the insulation looks flattened, it’s not just a comfort problem. It’s a health problem.
Our Owens Corning Blown In Insulation Process
We don’t do vague half-day arrival windows. We show up when we say we will, in uniform, background checked, ready to work.
- 1
You call (559) 666-2260. A live person answers. We ask about your house: square footage, build year, what you’re noticing upstairs. No pressure, just questions.
- 2
We inspect and measure. We check the full attic: depth, R-value, air leaks, existing insulation condition, visible signs of moisture or rodents. Bryce Holloway or one of his senior techs goes over every finding with you before pricing anything.
- 3
You get a written price. Not a ballpark. A line-item number for the work, whether that’s a top-up, a full removal and re-blow, or an air-seal plus insulation package. The number you approve is the number on the invoice. Period.
- 4
We do the work. If it’s a top-up, we match the existing Owens Corning material or install fresh loosefill to spec. If it’s a removal, we vacuum it out clean, seal air leaks, then blow in the new material to the R-value we agreed on. If you prefer a different brand, we also install Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, GreenFiber, and Reflectix for specific applications.
- 5
We test and document. Depth measurements written on the attic access, photos of the finished work, and a clear explanation of what changed and why it matters. No mystery.
- 6
You get the 365-Day Done Right Promise. A written guarantee for a full year. If the work fails in that window, we return and fix it at no charge. Free second visit included. That’s the rule, not an exception.
What Owens Corning Blown In Insulation Costs in Fresno
Here’s what we see across the Fresno market, based on the jobs we’ve done from the Tower District to Harlan Ranch:
| Scenario | Typical Range |
|---|---|
| Attic top-up to R-38 (1,200 sq ft, no removal) | $1,200 – $2,200 |
| Full removal and re-blow (contaminated or rodent-damaged insulation) | $2,800 – $4,500 |
| Air sealing plus blown-in insulation (typical 1,600 sq ft home) | $2,500 – $4,200 |
| Blown-in wall insulation (existing home, 1-2 rooms) | $900 – $1,900 |
What moves the price: current R-value, attic accessibility, whether the old material has to come out, and how much air sealing the house needs. If you’re in an older home off Van Ness with knob-and-tube remnants or no attic access, that’s a different job than a 2015 build out near Copper River. Estimates are always free and always in writing. Call (559) 666-2260 and we’ll give you an exact number, not a starting point.

FAQs
Is Owens Corning blown in insulation still under warranty if another company installed it?
Owens Corning offers a limited lifetime warranty on their blown-in products, but that warranty typically covers manufacturing defects in the material, not installation issues, settling, or air sealing problems. In our experience, most Fresno homeowners dealing with inadequate insulation have an installation or air-sealing problem the manufacturer’s warranty won’t touch. That’s a big reason we document everything: you should know precisely what’s covered and what’s not before anyone starts.
Can you top up Owens Corning insulation with a different brand?
Yes, and we often do. AttiCat and other Owens Corning loosefill products use a self-feeding system, but once the material is in the attic, the R-value per inch is what matters. We can match the depth and performance with a different brand and tell you exactly what we’re putting in and why. If you’d rather stick with Owens Corning, we’ll source it.
How fast can you get to my attic in Fresno?
Every job starts with a call to (559) 666-2260. We’ll schedule the inspection within a few days, and in most cases, the actual work is done within a week. Same-week availability is common. Emergencies, like a roof leak that soaked your insulation, get priority. Call us and we’ll give you a real answer, not a delivery window.
Should I repair or replace my existing Owens Corning insulation?
If the existing insulation is dry, clean, and at least two-thirds of the recommended depth, a top-up is the smart play. If it’s been rodent infested, water damaged, or it’s dusted with decades of Central Valley fine-particulate silt, removal and a fresh blow is the better long-term call. We’ll inspect and give you an honest recommendation with numbers on both options.
How much insulation do I actually need in a Fresno attic?
The short answer is R-38 to R-49 for attics in California’s Central Valley climate zone. That’s 12 to 16 inches of blown-in fiberglass, depending on the density. Many older homes around Fresno have R-19 or worse, which is why upstairs rooms cook in summer and run cold in winter. We’ll measure your current R-value and show you the math.
