How Demilec Products Fail - and How We Fix Them

Demilec makes solid spray foam, but every product line has weak points. Here’s what we actually see in Garden Grove homes during audits:

• Heatlok HFO and HFO Pro open-cell foam pulling away from roof decking. The HFO series uses a water-blown chemistry that can shrink slightly if installed during high humidity or if the substrate wasn’t fully dry. Against a Garden Grove summer, the decking expands and contracts, and we often find hairline gaps where foam has separated from the sheathing. We map the separation with thermal imaging and correct the connection points with targeted air sealing.
• Sealection 500 missing spots behind knee walls and soffit transitions. Sealection 500 is the open-cell line many Garden Grove installers used in the 2010s. It’s a good product, but the application window is short, and we regularly find unfoamed cavities behind blocking or around baffles where the installer just didn’t get the gun in. Our audit catches those voids with blower door testing plus infrared, then we fill them with compatible open-cell foam.
• Heatlok Soy 200 and off-ratio foam that never fully cured. The soy-based lines are more sensitive to mix temperature than installers realized. In older Garden Grove homes, we’ve found foam that’s still slightly tacky or crumbly years later, a sign the A and B sides weren’t running at the right ratio that day. Off-ratio foam loses R-value and can off-gas. We document it, then recommend removal and replacement rather than trying to patch over bad chemistry.
• APEX and APX 2.0 closed-cell foam installed too thin at rim joists. The APEX series is our go-to when we need high R-value per inch, but we’ve audited plenty of Garden Grove crawl spaces where the foam at the rim is barely an inch thick. That’s a code-minimum shortcut, not a performance install. Our crawl space portion of the audit reports the actual depth at every measured point and flags anything under spec.
• UV degradation on any exposed Demilec foam at eave returns. All Demilec foam, including the closed-cell lines, breaks down under direct sunlight. In Garden Grove, where eaves are short on ranch homes, we see chalky, powdery foam where the roof line meets the wall. It collapses over time and creates a direct thermal bypass. We replace the degraded section and re-coat per the manufacturer’s exposure limits.

These are the things a generic energy audit misses because the tech isn’t looking for brand-specific failure patterns. Our technicians know Demilec product behavior, and that’s the difference between an audit that says “your insulation looks fine” and one that finds the actual problem.

Our Demilec Home Energy Audit Process

Here’s what happens when you call us for a Demilec home energy audit in Garden Grove:

1. 1
   We talk first. You call, a live person answers, and we ask what you’re feeling in the house: hot rooms, drafts, smell, noise, bills. That shapes where we look hardest.
2. 2
   Blower door test. We depressurize the home and measure total air leakage. For a Demilec-foamed home, we’re looking for leakage rates that should be low, and if they’re not, we know foam isn’t doing its job somewhere.
3. 3
   Thermal imaging walk-through. We scan every wall, ceiling, and floor with an infrared camera. Gaps, voids, and settled foam show up as temperature differences. We photograph everything so you see exactly what we see.
4. 4
   Foam inspection at key transitions. Rim joists, attic kneewalls, can lights, plumbing penetrations, band boards. We check thickness, adhesion, and signs of off-ratio chemistry on your Demilec foam specifically.
5. 5
   Duct leakage test, if you have forced air. Ducts in Garden Grove attics leak more than most homeowners believe. We measure it and show you the percentage loss.
6. 6
   You get a plain-English report and a plan. We walk you through every finding, tell you what’s urgent and what can wait, and quote repairs in writing before any work starts. If you hire us for the fix, most jobs are done same week.

Every audit is backed by our 90-Day Done Right Promise. If we missed something within 90 days of the work being done, we make it right at no cost.

What Demilec Home Energy Audit Costs in Garden Grove

Here’s what we charge for Demilec-focused home energy audits in Garden Grove, based on the homes we most often service:

• Basic comfort audit (blower door + thermal imaging): $195 to $325 for homes up to 2,000 square feet. This is the most common request from Demilec owners who suspect their foam isn’t performing.
• Full home energy audit with duct leakage testing: $350 to $450 for larger homes or homes with multiple zones and crawl spaces. Add $49 if you want the attic air-sealed during the same visit.
• Foam condition inspection only, no blower door: $125 when you already suspect a specific problem area and just want our Demilec expertise on that spot.
• Standing discounts: $50 off any repair over $250, an $89 seasonal tune-up, and a permanent 5% Senior & Veteran discount on every audit and repair.

What moves the price is square footage, crawl space access, and whether we’re testing ducts that day. Every quote is upfront pricing, in writing, before we start. Call (657) 213-3642 for an exact quote. Estimates are free.

Why Garden Grove Homeowners Call Warmline Insulation Co. for Demilec Work

We’ve served Garden Grove since 2011, and we’ve crawled through more attics in West Garden Grove and the Euclid corridor than we can count. Those older ranch homes are some of the most rewarding to retrofit right because the original insulation decisions were rarely made with a 105-degree August in mind. Neil Ashford and the team know that a Demilec audit isn’t just about finding gaps; it’s about figuring out what the original installer got right and what they didn’t, so you don’t spend money fixing things that aren’t broken.

We also service other insulation brands like Reflectix, so our recommendations aren’t tied to one manufacturer’s product line. You get an honest read on what your home actually needs. Our technicians are background-checked, uniformed, and trained on Demilec foam behavior specifically. No upselling, no unnecessary scope. Do it right once and your house will tell the difference on the first hot day.
