Demilec Home Energy Audit in Pomona: What to Know First
A Demilec home energy audit in Pomona typically runs $195 to $495 depending on home size, and includes blower door testing, thermal imaging, and a full insulation inspection focused on how your Demilec foam is actually performing. Most audits are completed in about two to three hours, with a same-week report. This page is for Pomona homeowners who already have Demilec spray foam or are considering it, and want to know if their insulation is doing its job. Call (626) 341-0830 and a live person answers 24/7, no voicemail.
How Demilec Products Fail - and How We Find It
- Heatlok HFO shrinkage at rim joists. In Pomona’s dry inland heat, we regularly see Demilec Heatlok HFO pulling back from rim joist edges by an eighth to a quarter inch. The foam cures too fast when applied in high ambient temperatures, and that hairline gap becomes a convective air leak that a blower door picks up immediately. Our fix is targeted air sealing at the seam, then re-testing to confirm the leak is closed.
- Sealection 500 open-cell density issues. Open-cell Demilec Sealection 500 can settle or under-expand if the installer’s mix ratio drifted during application. We find this most often in Pomona homes where the foam was sprayed in a single pass during a hot afternoon. Thermal imaging shows uneven R-value across the cavity, and we document it so you know exactly where supplemental insulation makes sense.
- Vapor permeability mismatches in crawl spaces. Demilec’s open-cell lines are vapor permeable, which is fine in a vented attic but problematic in a closed Pomona crawl space. We audit whether that foam is allowing moisture to reach the subfloor, and whether a vapor barrier retrofit or closed-cell replacement is the smarter fix for your specific house.
- UV degradation on exposed Heatlok Soy. Any Demilec foam left exposed to Pomona’s intense summer sun degrades within months, turning from off-white to a crumbly amber. Our audit flags exposed foam around attic hatches, knee walls, and skylight shafts, then we recommend either covering it with a UV-stable barrier or replacing the damaged section.
- No thermal barrier over living-space foam. Building code requires a thermal barrier (typically drywall) between Demilec foam and occupied rooms. In older Pomona bungalows, we occasionally find spray foam in basements or garage conversions where the drywall never went up. It’s a fire safety issue and an E-E-A-T callout we never skip.
Our Demilec Home Energy Audit Process
We treat every Demilec audit as a diagnostic, not a sales call. Here’s how it runs:
- 1
Call and schedule. A live person answers, asks about your home’s age, square footage, and where you’re noticing drafts or hot rooms.
- 2
Walkthrough and visual inspection. Our tech examines accessible Demilec foam, looking for the specific failure modes above: shrinkage, UV damage, density inconsistencies, missing thermal barriers.
- 3
Blower door test. We depressurize the house and measure air leakage in cubic feet per minute. This number tells us how much conditioned air you’re losing through gaps the eye can’t see.
- 4
Thermal imaging. An infrared camera scans walls and ceilings to map insulation voids, settling, and thermal bridging around the Demilec foam.
- 5
Duct leakage test (if applicable). Leaky ducts in a Pomona attic can waste 20 to 30 percent of your HVAC output, even with perfect foam. We quantify it.
- 6
Report and honest recommendation. You get a written summary with photos, readings, and a prioritized list. If nothing’s wrong, we tell you that. If something is, we tell you what it costs to fix and why. Backed by the 90-Day Done Right Promise, then done.
What Demilec Home Energy Audit Costs in Pomona
Here’s the honest breakdown for Pomona homes:
- Basic audit (blower door + thermal imaging): $195 to $295 for homes under 2,000 sq ft.
- Full diagnostic (adds duct leakage and moisture assessment): $350 to $495 for larger or older homes.
- Targeted audit (single room or area of concern): $145 to $195, common for one hot bedroom or a drafty crawl space.
The price moves based on square footage, number of zones tested, and whether we’re also inspecting exposed foam in attics or crawl spaces. We don’t pad the bill with surprise line items. Call (626) 341-0830 for a free estimate, and ask about the $50 Off Any Repair Over $250 if your audit turns up an issue we need to fix.

Comfortable homes don’t happen by accident, they’re built decision by decision, and we help you make the right ones.
FAQs
No. An independent diagnostic audit doesn’t void your Demilec warranty. In fact, having documented readings can help substantiate a warranty claim if the foam was installed incorrectly. As an independent Demilec service provider, we don’t represent the manufacturer, but our testing methods align with industry standards and won’t damage your foam.
Yes, in most cases. Small shrinkage gaps, UV-damaged sections, and missing flash-and-fill areas can often be addressed same-visit with a compatible closed-cell touchup. Larger issues, like full cavity re-foaming, may require a second trip. Call (626) 341-0830 for an exact timeline, estimates are free.
Repair is almost always cheaper when the problem is localized. We’ll tell you honestly if replacement makes more sense because the foam is too thin, too damaged, or improperly installed. We won’t sell you a full replacement if a targeted fix does the job. That’s an assessment Neil’s crew has made hundreds of times in Pomona homes.
Same-week scheduling is typical, and a live person answers 24/7 to book your audit. We don’t route you through an answering service. If you’ve got a drafty room or a heat wave coming, we’ll do our best to get a technician out quickly, and most audits are completed in a single visit.
Yes. The $89 Seasonal Tune-Up applies to smaller diagnostic checks, and there’s a permanent 5% Senior & Veteran discount on every service. The $50 Off Any Repair Over $250 applies if your audit finds a repair needed. Call (626) 341-0830 and we’ll walk you through which offer applies to your situation, no fine print games.
