Demilec Home Energy Audit in Pomona: What to Know First
We provide independent Demilec home energy audit in Pomona, typically scheduled within 48 hours and completed in a single visit. Most audits run between $280 and $520 depending on home size and the number of thermal zones we need to map. We do not quote over vague descriptions - we send a written scope and flat price before any work starts, and that price does not change once you approve it.
This page is for Pomona homeowners with Demilec spray foam or coating products who want to know whether their insulation is performing to spec, where conditioned air is escaping, and what the fix costs before anyone walks through the door. If you are seeing uneven temperatures between rooms, rising utility bills, or suspect your Demilec application was not installed to the manufacturer’s density requirements, call (562) 242-7569. We answer live, 24/7.
How Demilec Products Fail - and How We Fix Them
- Demilec Heatlok HFO Pro shrinkage at rim joists. The HFO blowing agent in this closed-cell series can pull away from sill plates in Pomona’s combination of hot, dry summers and occasional winter moisture intrusion. We find the gap with thermal imaging, cut back the failed section, and reapply to the manufacturer’s minimum 2-inch thickness after sealing the sill-to-foundation joint with acoustic sealant.
- Demilec Sealection 500 open-cell overspray into soffits. This mid-density open-cell foam is common in Pomona’s 1980s-2000s tract homes. Installers often blew it past the thermal boundary into vented soffit cavities, creating a direct path for attic air to enter the wall assembly. We identify the intrusion with boroscope inspection, remove the overspray, and install proper blockers before adding insulation.
- Demilec 500 spray foam surface degradation from UV exposure in unvented attics. When Demilec 500 is left exposed in conditioned attics without a thermal or ignition barrier coating, Pomona’s intense solar gain through roof sheathing accelerates surface oxidation. We measure the degradation depth, remove friable material, and re-coat or cover with an approved barrier - never just paint over it.
- Demilec Heatlok XT missed adhesion on OSB roof decks with factory-applied sealant. The XT series demands a clean, dry substrate; some Pomona builders installed it over OSB with mill-applied wax or sealant residue. We test adhesion with a pull-strip sample, scarify the deck if needed, and reapply to Demilec’s stated 50-degree minimum substrate temperature - a threshold we verify with infrared thermometer, not guesswork.
- Demilec open-cell moisture retention in exterior walls with stucco cladding. Pomona’s stucco-heavy housing stock traps bulk water when open-cell foam is used on exterior walls without a proper drainage plane. We run a moisture-meter survey of the wall cavity, correlate readings with thermal imaging, and specify closed-cell replacement or exterior retrofit only after we know where the water is coming from.
Our Demilec Home Energy Audit Process
- 1
Call and scope. You describe the home, the Demilec product if known, and the symptoms. We schedule and send a written price before arrival - Haven Standard Clause 1.
- 2
Blower-door test. We depressurize the house to 50 Pascals - a standard pressure differential - and measure CFM50, the cubic feet per minute of air leakage. This gives us a single number to beat after any work.
- 3
Thermal imaging and boroscope inspection. We map Demilec-specific failure patterns: shrinkage, overspray, UV degradation, adhesion loss. We document everything with photos you receive in your report.
- 4
Duct leakage test if indicated. Many Pomona homes with Demilec spray foam still lose 20-35% of conditioned air through duct seams. We pressurize the duct system and measure leakage to outside.
- 5
Written findings and flat-price repair scope. No open-ended proposals. You get a line-item scope, a single price, and a 365-Day Done Right Promise in writing before any work starts.
- 6
Post-work verification. On applicable jobs, we run a second blower-door test and publish the before-and-after numbers so you can verify the air-sealing result yourself.
Before
AfterWhat Demilec Home Energy Audit Costs in Pomona
| Service | Typical Range | What Moves the Price |
|---|---|---|
| Single-zone thermal imaging audit, Demilec inspection | $280-$380 | Home under 1,800 sq ft, one attic access, foam accessible |
| Multi-zone audit with blower-door test | $380-$520 | Additional thermal zones, complex rooflines, multiple Demilec applications |
| Duct leakage test add-on | $120-$180 | Duct accessibility, number of returns and supplies |
| Demilec repair scope (after audit) | $850-$2,400 | Area of failed foam, accessibility, need for removal vs. overlay |
Homes near Ganesha Park and the older ranch stock north of the 10 Freeway often run toward the higher end - smaller attics with more penetrations to seal, and original Demilec applications from the 2008-2014 retrofit boom that are now showing age. We do not charge for the audit if you proceed with a repair scope we propose. Call (562) 242-7569 for a written estimate - estimates are free, and we offer a Free Second Opinion on any competing written quote.
Why Pomona Homeowners Call Topside Attic Insulation Pomona for Demilec Work
We are an independent Demilec service provider - not affiliated with or authorized by the manufacturer - which means we evaluate your foam on its performance, not its warranty status. Wes Okafor has logged more bypasses in Pomona Valley ranch homes than he cares to count, and our crews run a blower-door test before any material goes in so the R-value on paper matches what the house actually performs. Seal the leaks first. The insulation is just the last layer of the answer.
Our materials come from Demilec, Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, and GreenFiber - no proprietary lock-in. If your situation calls for a Reflectix radiant barrier supplement or a different brand’s foam entirely, we will say so in the written scope. Every job closes with a Documented Photo Record and, where applicable, published blower-door numbers. The 365-Day Done Right Promise applies to all completed work. Calls are answered by a live person, 24/7.
FAQs
No. As an independent service provider, our audit is non-destructive thermal imaging, blower-door testing, and visual inspection - we do not alter the foam or submit claims to Demilec. If you need manufacturer warranty service, we will note that in our written findings so you can pursue it separately. Call (562) 242-7569 to schedule - estimates are free.
We source Demilec products through standard distribution channels and will specify the matching series - Heatlok HFO Pro, Sealection 500, or Heatlok XT - in your written scope. We also stock compatible closed-cell and open-cell alternatives from Johns Manville and Icynene if lead time or cost makes more sense for your job. The choice is yours, documented in writing before work starts.
Spot repairs typically run $850-$1,400; full removal and reapplication in a Pomona attic runs $2,000-$2,400. We recommend repair when the failure is localized shrinkage, UV surface degradation, or overspray - all fixable without disturbing sound foam. Full replacement makes sense when adhesion failure is widespread or moisture has compromised the substrate. Our audit tells you which category you are in before you spend anything.
We schedule within 48 hours and complete the audit in one visit, usually 2-3 hours. Same-day service is often available for homes near downtown Pomona or along Holt Avenue. We send your written findings and photo documentation within 24 hours of the visit. Call (562) 242-7569 to check today’s availability - estimates are free.
You receive a written report with thermal images marked with temperature readings, blower-door CFM50 results if tested, moisture-meter readings where taken, a line-item repair scope with flat pricing if needed, and a photo record of every area we accessed. This is standard on every job, not available on request. Under Haven Standard: you get the documentation before you decide, not after you pay.
