Demilec Home Energy Audit in Glendale: What to Know First

An independent Demilec home energy audit in Glendale typically runs $295 to $495 for a full blower door test and thermal imaging inspection, and most reports are delivered within 24 to 48 hours. At Walt’s Insulation, we don’t sell audits as a loss leader to push new insulation; we charge a straight fee and tell you exactly what your Demilec spray foam is doing, where it’s failing, and what actually needs fixing, even when the answer is “nothing.”

Call (747) 246-7237

This page is for homeowners in Glendale who had Demilec spray foam installed, have a funny feeling their energy bills don’t match the sales pitch, and want a real diagnostic, not another product demo. We’ve been inspecting Demilec installations in Glendale homes for years, and we can usually tell you within the first hour of testing whether your foam is doing its job. Call (747) 246-7237 and a live person answers, day or night.

How Demilec Products Fail - and How We Fix Them

Demilec makes solid spray foam products, but no foam is set-and-forget in Glendale’s climate. Here’s what we actually find during audits:

• Heatlok HFO off-ratio application. The most common problem we find in Glendale homes with Demilec’s Heatlok HFO line is off-ratio spray, which happens when the A and B sides aren’t mixed at the right temperature or pressure during install. The foam cures but never reaches its rated R-value, and the homeowner paid full price for a product performing at 60 to 70 percent of its spec. During an audit, a thermal imaging scan shows uneven surface temperatures that tell us the foam went on inconsistent. The fix may be a localized removal and re-spray, or in slab and wall cavities, we document the readings for warranty conversations with the original installer.
• Sealection 500 shrinkage at wall-to-ceiling transitions. Demilec’s Sealection 500 open-cell foam is a good product, but we inspect a number of Glendale homes where it has pulled back from framing members at the top plates and around windows. This is often installer error: spraying too thick in one pass traps heat and the foam contracts as it cools. The result is a hairline gap that lets conditioned air escape. A blower door test finds these fast. We air-seal the gaps with a compatible sealant and, where needed, add a flash layer to restore the air barrier.
• Heatlok Soya UV degradation in exposed knee walls. If you have Demilec Heatlok Soya foam in an attic knee wall or any spot where it catches reflected sunlight through a vent, that foam is unprotected after its first summer. Open-cell and closed-cell foams both break down under UV, but Soya’s lighter density means it crumbles faster. We see it in Glendale attics all the time. The fix is a protective coating or a cover layer. Ignoring it means the foam keeps degrading and you keep losing R-value.
• Voids behind electrical boxes and plumbing chases. Demilec foam performs best with a continuous air barrier, but any install involves cutouts for junction boxes, can lights, and plumbing. In a lot of Glendale homes we audit, these areas were never re-sealed after the rough-in work. The blower door test shows exactly where those leaks are; then we foam or caulk them with materials compatible with the original Demilec product so we don’t void any remaining coverage.
• Open-cell foam saturation from undiagnosed roof leaks. Sealection 500 and other Demilec open-cell products absorb water. If you have a small roof leak you never noticed, that foam is holding moisture against your framing, and in Glendale’s dry summers plus wet winters, that cycle accelerates. A thermal imaging inspection during an audit flags the wet spots before they become mold or rot. Finding this early saves you a much larger project later.

Our Demilec Home Energy Audit Process

Here’s how a Demilec home energy audit works when you call Walt’s Insulation, from first call to the report in your hand:

1. 1
   Call (747) 246-7237. A live person answers. We ask about your home’s age, the type of Demilec product you believe was installed, and what you’re noticing: high bills, hot rooms, drafts, or just curiosity. We schedule the audit at a time that works for you, same week in most Glendale neighborhoods.
2. 2
   We walk the attic, walls, and crawl space. Our technician, background-checked and uniformed, inspects every accessible area. We note the Demilec product line if we can identify it, check the foam’s depth and coverage, and photograph what we find. You get copies of every photo.
3. 3
   Blower door test. We set up the calibrated fan in an exterior doorframe, depressurize the house, and measure air leakage in cubic feet per minute. For Demilec foam homes, the number we’re comparing against is the tightness the product should deliver when installed correctly. If yours is off, we know leaks are present.
4. 4
   Thermal imaging inspection. We scan walls, ceilings, and floors with an infrared camera. This shows missing foam, wet insulation, thermal bridging, and air leaks. It’s the single most revealing test for Demilec work because spray foam problems hide inside walls.
5. 5
   Duct leakage test where relevant. If your ductwork runs through unconditioned space, we test it. Glendale homes with attic ducts lose a surprising amount of conditioned air to leaks, and Demilec foam can’t help if the ducts are bleeding.
6. 6
   Cleanup and report. We leave the house exactly as we found it. Within 48 hours, you get a written report with readings, photos, and prioritized recommendations. We walk you through it on the phone or in person, and you decide what to fix, on your timeline, with no pressure.

What Demilec Home Energy Audit Costs in Glendale

The cost of a full Demilec home energy audit in Glendale, with blower door and thermal imaging, runs between $295 and $495 depending on home size and whether we’re testing ducts too. Here’s how that breaks down:

• Blower door test alone: $150 to $250
• Thermal imaging inspection alone: $150 to $300
• Combined full audit (blower door + thermal): $295 to $450
• Full audit with duct leakage test: $395 to $495

What moves the price is square footage, number of floors, and whether we’re testing a detached garage or accessory dwelling unit as well. Older Glendale homes with finished walls sometimes need additional time to locate thermal anomalies. If we do an audit and you hire us for the repairs, we credit the audit fee toward the work. Call (747) 246-7237 for a firm quote; we don’t give vague estimates.

Why Glendale Homeowners Call Walt’s Insulation for Demilec Work

We’re the one down the road, not a national franchise with an 800 number and a rotating cast of subcontractors. Walt’s Insulation has been locally owned and owner-operated since 2000, and Walt Brenner himself has been working Glendale long enough to know which neighborhoods have older framing, which tract homes got fast-and-loose foam jobs, and what summer heat does to spray foam in an attic that hits 140 degrees. When we inspect Demilec foam, we’re not selling you anything except an honest answer.

Every job we do is covered by the Done Right Promise: if it’s not done right, we make it right, for as long as you own the home. Our technicians are background-checked and uniformed, so you know exactly who’s walking through your door. And if you have a mix of insulation products, say Demilec foam in the attic and Reflectix on a garage door, we handle that too. We work with whatever’s in your Glendale house and tell you what’s actually worth fixing.
