Demilec Home Energy Audit in Campbell: What to Know First
We provide independent Demilec home energy audit in Campbell, typically completed same-day with written results delivered before we leave. Most audits run between $280 and $550 depending on home size and which Demilec assembly we’re evaluating, and we do not start any work without a written price you approve first. This page is for Campbell homeowners with Demilec spray foam or hybrid insulation systems who need a documented performance reading, suspect their envelope is underperforming, or want blower-door verification before adding more material. Call (831) 534-3206 for a free estimate.
How Demilec Products Fail - and How We Fix Them
- Heatlok HFO Pro series shrinkage at roof decks. The HFO blowing agent can contract 3-5% in the first two heating seasons, pulling away from rafter bays in Campbell’s sun-baked attics. We map the gaps with thermal imaging, remove the compromised sections, and reapply only after sealing the full perimeter with compatible transition foam.
- Demilec Sealection 500 overspray into soffits blocking ventilation. Installers sometimes blow this open-cell foam past the thermal boundary into eave vents, choking the intake path. Our audit includes a smoke-pencil test at every soffit - if we find blockage, we surgically remove the foam and reinstall baffles before any new insulation touches the attic floor.
- Heatlok XT adhesive failure on OSB in high-moisture crawl spaces. Campbell’s clay-heavy soils hold moisture against foundation walls; the XT skin delaminates rather than the foam itself failing. We do not patch over it. We strip to substrate, treat for moisture source, and reapply with a vapor-barrier-integrated approach.
- Sealection Agribalance density inconsistencies in wall cavities. This bio-based line can vary in cell structure when sprayed in temperatures below 55°F, which happens regularly in Campbell’s January mornings. Our thermal scan identifies the low-density pockets that read as hot spots; we fill them with matched material rather than topping with incompatible foam.
- Hybrid system thermal bridging at Demilec-to-fiberglass transitions. When Demilec spray foam meets batt insulation without an air barrier at the junction, conditioned air bleeds through the gap. We see this most in Campbell’s 1970s ranch additions where the original R-19 meets newer spray foam at the addition line. Our fix is a sealed transition zone, not more insulation on one side.
Our Demilec Home Energy Audit Process
- 1
Call and scope. A live person answers, asks which Demilec product you have if you know it, and schedules. You get a text when the technician is en route.
- 2
Blower-door baseline. We run a pressurization test - a measurement that shows, in one number, how much air your building envelope is losing. This goes on your report as the “before” figure.
- 3
Demilec-specific thermal imaging. Our FLIR is tuned for spray foam density variations. We know Heatlok HFO Pro shrinks differently than Sealection 500 degrades; the camera confirms what the blower door suggested.
- 4
Written findings and price. Before any repair work, you receive a documented photo record, the blower-door reading, and a flat price for recommended corrections. No work starts without your written approval.
- 5
Repair and verification. We seal first, then insulate - in that order. After completion, we run the blower door again and hand you a printed report with both numbers.
- 6
Documentation and warranty. Your 365-Day Done Right Promise paperwork, the photo record, and the blower-door results are delivered before we leave. Haven Standard: Have it in writing.
Before
AfterWhat Demilec Home Energy Audit Costs in Campbell
| Service | Typical Range | What Moves the Price |
|---|---|---|
| Basic Demilec audit (blower door + thermal scan) | $280-$380 | Home size under 2,000 sq ft, single attic zone |
| Full Demilec envelope audit with duct leakage test | $420-$550 | Multiple zones, crawl space included, HERS-style documentation |
| Demilec repair after audit (per zone) | $180-$340 | Accessibility, foam removal required, moisture remediation |
Homes near the Pruneyard Plaza corridor, built in the 1960s and 1970s with later Demilec retrofits, often need more time at the transition zones where old meets new. That extra time is in the written price before we start, not a surprise after. Call (831) 534-3206 for an exact quote - estimates are free.
Why Campbell Homeowners Call Topside Attic Insulation Campbell for Demilec Work
We’ve served Campbell long enough to know the specific air-sealing problems this city’s housing stock presents before we ever touch a bag of blown-in cellulose. Wes Okafor and our crew publish before-and-after blower-door numbers on every applicable job - a pressurization measurement that quantifies exactly how leaky an envelope was and what changed. We are an independent Demilec service provider, not a factory-authorized dealer, which means we source quality materials from Demilec, Reflectix, Owens Corning, and others with no proprietary lock-in. The 365-Day Done Right Promise applies to everything we complete, and a live person answers calls 24/7. Seal the leaks first. The insulation has nowhere useful to go until you do.
FAQs
No. Demilec’s product warranty covers material defects, not the condition of your building envelope. Our audit is non-destructive and documents rather than alters the foam. If we find a material defect during inspection, we flag it for your warranty claim and can provide the blower-door data Demilec may request. Call (831) 534-3206 to schedule - estimates are free.
We source Demilec products directly when the application calls for matched material, particularly for Heatlok HFO Pro and Sealection 500 continuity repairs. For some transition zones and vapor-barrier work, we use compatible third-party foams that perform to the same spec. We tell you which before any work starts, and the choice is in the written scope you approve. Call for specifics on your assembly.
The blower-door test answers this. If the foam itself is intact but the home still leaks, the problem is the gaps around it - top plates, can lights, attic hatches. If the foam has shrunk, delaminated, or degraded, it needs removal and replacement. Our thermal imaging distinguishes between these two scenarios before you spend money on the wrong fix. Call (831) 534-3206 for a free estimate.
Most audits are scheduled within 48 hours and completed in two to three hours on site. Same-day service is often available for suspected active issues like crawl space moisture or visible foam degradation. You get preliminary blower-door results before we leave, full documentation within 24 hours. Call to check today’s availability.
Yes. We regularly evaluate hybrid assemblies where Reflectix radiant barrier faces Demilec spray foam in roof decks or crawl spaces. The audit accounts for how these two materials interact thermally and where the air barrier continuity breaks between them. Our report addresses the system, not individual products in isolation. Call (831) 534-3206 to schedule.
