Owens Corning Home Energy Audit in Fullerton: What to Know First
An Owens Corning home energy audit in Fullerton typically runs $199 to $499 depending on home size and how many tests you need, and we can usually get a technician to your door within 48 hours. That price covers a blower door test, thermal imaging walkthrough, insulation inspection, and a straight answer about where your home is losing energy, no upsell attached. This page is for Fullerton homeowners who want to know exactly what’s happening behind their walls and above their ceilings, especially in homes with Owens Corning fiberglass or spray foam already installed. If you’d rather skip the reading and talk to a real person, call (657) 216-9948 and Walt or one of the crew will pick up.
How Owens Corning Products Fail - and How We Find It During an Audit
Owens Corning makes solid insulation, but nothing lasts forever in a Fullerton attic. Here’s what we actually see during home energy audits on homes with Owens Corning products:
- Owens Corning pink fiberglass batts compressing under storage. Homeowners stack boxes on top of R-30 batts in the attic and compress them to R-19 or worse. We find this constantly in older Fullerton ranch-style homes near the Arboretum. Compressed fiberglass loses most of its R-value, and the fix is usually fluffing and supplementing with blown-in insulation on top.
- Owens Corning AttiCat blown-in settling below the intended depth. AttiCat is a good product, but if it was installed at the minimum depth years ago and never topped off, Fullerton’s summer heat cycles settle it further. During a thermal imaging pass, we spot thin zones over bedrooms and bonus rooms where the ceiling reads 10 to 15 degrees warmer than the rest of the house. The fix is topping it off to the correct R-value for our climate zone.
- Owens Corning Foamular rigid board gaps around rim joists. In crawl spaces and basement-adjacent areas, we see Foamular boards that were cut a half-inch too narrow or never sealed at the seams. Air leaks right around the edges, and the homeowner paid for continuous insulation they’re not actually getting. Our duct leakage test and blower door numbers confirm it before we recommend re-sealing the seams with foam or caulk.
- Owens Corning ProPink spray foam pulling away from framing. In Fullerton, where we get real temperature swings between day and night, spray foam that was installed over dusty or damp framing can pull away just enough to create air channels. A blower door test will show higher ACH50 numbers than the home should have for its size, and thermal imaging reveals the cold or hot streaks along the wall top plates. The fix is targeted air sealing at the gap.
- Rodent damage in Owens Corning fiberglass. Rats and mice love pink fiberglass. It’s warm, fluffy, and easy to tunnel through. In Fullerton neighborhoods with mature trees and older homes, we regularly find rodent-damaged Owens Corning batts during an audit, especially near the eaves and plumbing penetrations. The audit catches it early before the damage spreads, and we can quote removal and replacement with rodent proofing included.
Our Owens Corning Home Energy Audit Process
Here’s how it works when you call us about an Owens Corning home energy audit in Fullerton:
- 1
You call (657) 216-9948. A live person answers, day or night. We ask about your home’s square footage, year built, and what’s making you suspect energy loss. No script, no call center.
- 2
We schedule a time that works. Usually within 48 hours. We show up in a marked vehicle with a uniformed, background-checked technician.
- 3
Blower door test first. We depressurize the house and measure exactly how leaky it is. This gives us a baseline ACH50 number we can compare against what a home your size should be hitting.
- 4
Thermal imaging walkthrough. We scan ceilings, walls, and floors with an infrared camera. This is where compressed Owens Corning batts, settled AttiCat, and spray foam gaps light up like a sore thumb.
- 5
Insulation and ductwork inspection. We get into the attic and crawl space, check your Owens Corning product’s actual depth and condition, and run a duct leakage test if your system’s in the attic or crawl space, which most Fullerton homes are.
- 6
You get a written report and straight answers. We tell you what’s fine, what’s costing you money, and what it would cost to fix. No scare tactics. If we recommend work, we back it with our Done Right Promise: if it’s not done right, we make it right.
What Owens Corning Home Energy Audit Costs in Fullerton
Here’s what you’re looking at for a full Owens Corning-focused home energy audit in Fullerton:
- Blower door test only: $150-$250
- Thermal imaging inspection only: $175-$275
- Full audit (blower door + thermal imaging + insulation inspection): $299-$449 for homes up to 2,000 sq ft
- Full audit with duct leakage test: $399-$549 for larger homes or homes with both attic and crawl space ductwork
- Attic-only insulation inspection: $125-$200
What moves the price is home size, access difficulty (steep attic stairs, tight crawl spaces), and whether we’re testing ducts in one zone or two. We don’t charge a trip fee inside our service county, and every audit comes with a written report you can use to make decisions. Seniors and veterans always get 10% off, and if you’ve got a written estimate from another company, bring it in and we’ll give you a free second opinion. Call (657) 216-9948 for an exact quote.

FAQs
For compressed or rodent-damaged fiberglass, replacement or topping off is almost always cheaper in the long run than trying to re-fluff old batts, which never recover their full R-value. For settled AttiCat, topping off is the cheaper fix and typically costs $0.80 to $1.50 per square foot in Fullerton. We’ll show you the numbers before you commit to anything. Call (657) 216-9948 for a free estimate.
We can usually get to your Fullerton home within 48 hours, and the audit itself takes two to three hours for most homes. Same-week appointments are common. If you’ve got a specific concern like a hot bedroom or a drafty hallway, let us know when you call and we’ll make sure the technician spends extra time there.
No. A diagnostic audit doesn’t alter or void your Owens Corning product warranty. We’re an independent Owens Corning service provider, not a manufacturer representative, but everything we do is diagnostic and doesn’t affect the product’s warranty status. If we do recommend repairs or replacement, we’ll walk you through what the warranty covers before we start.
Yes, and it’s more common than most Fullerton homeowners expect, especially in neighborhoods with older trees and raised foundations. Thermal imaging won’t show rodents directly, but when we get into the attic we see tunnels through Owens Corning batts, droppings, and chewed duct insulation. We’ll document it with photos and quote removal, replacement, and rodent proofing in one straight number.
Yes. Some homeowners want the numbers and the report and that’s it. You’ll get a written summary of your blower door results, thermal images, and specific observations about your Owens Corning insulation’s condition. If you want a quote for fixes, we provide one. If you don’t, we’re done. No follow-up calls trying to wear you down. That’s how we’ve done business since 2000.
