Demilec Home Energy Audit Nationwide

Demilec Home Energy Audit in Irvine: What to Know First

A Demilec home energy audit in Irvine tells you exactly where your spray foam or insulation is underperforming, using blower door testing and thermal imaging to pinpoint air leaks, thermal gaps, and moisture issues. We typically complete the full diagnostic in 60 to 90 minutes and walk you through the findings before we leave, so you understand exactly what’s going on in your attic and walls. Pricing is straightforward and quoted upfront, with no surprise fees added after the fact.

Call (949) 832-7835

This page is for Irvine homeowners who have Demilec spray foam or Demilec insulation in their home and need someone who actually understands how these specific products age, fail, and interact with Southern California’s coastal climate. If your energy bills keep climbing in Woodbridge or Turtle Rock despite having foam installed years ago, call (949) 832-7835 and a live person answers, 24/7.

How Demilec Products Fail - and How We Fix Them

• Heatlok HFO shrinkage at the roofline. Demilec’s Heatlok HFO spray foam line is a closed-cell product, and in Irvine’s summer heat, we’ve seen installations from the 2010s develop hairline separations where the foam meets the roof deck. The foam pulls back just enough to open a thermal bypass, and the homeowner notices the upstairs running warm no matter how low the AC is set. We identify this with thermal imaging during the audit, then remove the failed section and re-foam with a compatible closed-cell product.
• Sealection 500 settling in older homes. Demilec’s Sealection 500 is an open-cell foam that was popular in Irvine track homes built in the 1990s and early 2000s. It does not shrink the way closed-cell does, but we’ve found it can settle or compact in wall cavities when it was sprayed at the wrong temperature or thickness. The audit picks up inconsistent R-value across the wall plane, which reads on thermal imaging as vertical striping. The fix is typically blowing dense-pack cellulose or injecting additional foam into the compromised cavities.
• Agribalance off-gassing and density issues. Demilec’s Agribalance line uses a soy-based component, and while it is an effective insulator, we’ve seen batches that were mixed incorrectly by the original installer, leaving the foam spongy and less dense than spec. The blower door test on these homes shows higher than expected air leakage, because the foam never fully expanded to seal the framing. We document this during the audit and replace the affected areas.
• Moisture trapped against Demilec foam in crawl spaces. Irvine’s proximity to the coast means crawl spaces run damp, and Demilec foam is not inherently a vapor barrier in all configurations. When open-cell Demilec foam was applied directly to the subfloor or crawl space rim joists without a vapor barrier behind it, we see the foam wicking moisture off the concrete. The audit finds elevated humidity and sometimes mold at the foam edges. Our fix is removal, proper barrier installation, and re-foaming only where the assembly will actually dry.
• Rodent and pest damage to Demilec foam. Foam is not pest-proof. In Irvine neighborhoods with established landscaping like Northwood and Woodbridge, rats and mice chew through Demilec foam in attics and rim joists, creating air and thermal leaks. A home energy audit with blower door testing will flag the pressure changes, and thermal imaging shows the voids. We handle the full repair: remove the damaged foam, rodent-proof the entry points, and re-foam.

Our Demilec Home Energy Audit Process

1. 1
   Call and schedule. A live person answers at (949) 832-7835, takes down your address and what you’ve been noticing, and we set a time that works with your schedule. Most Irvine audits happen within a few days.
2. 2
   We walk the property. Our background-checked, uniformed technician starts outside and works inward, looking at your attic, walls, crawl space, and any visible Demilec foam for signs of age, damage, or poor installation from the original spray.
3. 3
   Blower door test. We depressurize the house with a calibrated fan and measure exactly how much air is leaking through your building envelope, including through Demilec foam that has pulled away from framing or has been chewed through.
4. 4
   Thermal imaging inspection. An infrared camera shows us the temperature differences inside your walls and ceilings. Gaps in Demilec foam read as hot or cold streaks that we document and explain to you room by room.
5. 5
   Duct leakage test and insulation inspection. We check ductwork for leaks that waste conditioned air and measure the depth and coverage of any Demilec insulation in your attic, including areas that have shifted or compacted.
6. 6
   You get a written report and a straight answer. We sit down with you, show you the images and numbers, and tell you exactly what needs attention now, what can wait, and what it will cost. No pressure, no mystery line items. And like every job we do in Irvine, the work is covered by our 90-Day Done Right Promise.

What Demilec Home Energy Audit Costs in Irvine

For Irvine homes with Demilec foam or Demilec insulation, a full energy audit including blower door, thermal imaging, duct leakage testing, and a written report runs between $395 and $695 depending on square footage and access. If we find foam that needs removal and replacement, that work is quoted separately and typically starts around $1,200 for isolated repairs in attics or rim joist areas. Whole-attic re-foam jobs run higher, and we will walk you through the exact number before any work starts.

A few things move the price: how much of the original Demilec installation was done poorly, whether we are dealing with rodent damage or moisture, and how accessible your attic and crawl space are. Homes in older Irvine tracts with low-pitch roofs tend to have tighter attics, which makes removal slower. Every estimate is upfront, and we never add fees after the fact. Call (949) 832-7835 to schedule an audit, and remember: our $50 Off Any Repair Over $250 applies if the audit turns up work you want us to do.

Why Irvine Homeowners Call Warmline Insulation Co. for Demilec Work

We have been in business since 2011, and our founder, Neil Ashford, has been working Irvine homes long enough to know which Demilec installations from the early 2000s are holding up and which are quietly failing. Comfortable houses don’t happen by accident - they’re built that way on purpose. That’s the standard we bring to every audit and every repair.

You don’t have to schedule separate contractors for the diagnosis, the foam removal, the re-insulation, and the air sealing. We handle all of it under one roof, which means one crew, one warranty, and most jobs completed in a single visit. If a Demilec product is no longer the right fit for your home, we also work with Reflectix and the full range of materials from Owens Corning, Rockwool, CertainTeed, Icynene, Johns Manville, Knauf, and GreenFiber.

Every technician we send is background-checked and uniformed. Phones are answered by a live person 24/7. And every job is backed by the 90-Day Done Right Promise: if it’s not done right, we make it right. We also offer a permanent 5% Senior & Veteran discount and an $89 Seasonal Tune-Up.
