Demilec Home Energy Audit in Long Beach: What to Know First
We provide independent Demilec home energy audit in Long Beach, typically completed same-day with written findings delivered before we leave. Most audits run between $280 and $520 depending on square footage and whether duct leakage testing is included. We do not quote over the phone without seeing the home, but we do guarantee a written price before any work starts, every time.
This page is for Long Beach homeowners with Demilec spray foam or hybrid insulation systems installed between 2010 and 2023 who are seeing uneven temperatures, rising energy bills, or suspect their original contractor skipped air sealing. We also service Reflectix radiant barrier systems when they’re part of the same envelope. Call (424) 415-7031 to schedule, or text us if you prefer. A live person answers either way, 24/7.
How Demilec Products Fail - and How We Fix Them
- Heatlok HFO Pro shrinkage at rim joists. The HFO blowing agent in this high-performance closed-cell series can contract 3-5% during cure in cooler applications, pulling away from sill plates in Long Beach crawl spaces where marine layer keeps concrete below 60°F for months. We find the gap with a borescope, remove the failed section, and reapply only after the substrate is warmed and primed. Measure first, then insulate - otherwise you’re just trapping the problem.
- Demilec 500 open-cell overspray into soffit vents. Builders in Bixby Knolls and California Heights retrofits often used 500-series open-cell for cathedral ceilings, then buried the vent channel. The foam looks intact but the attic can’t breathe. Our thermal camera spots the blocked airflow pattern in about ninety seconds. We surgically remove the plug, restore the vent path, and replace with a vapor-smart assembly that doesn’t repeat the mistake.
- Heatlok XT adhesive failure on stucco substrates. Demilec’s XT series demands a clean, dry substrate; Long Beach stucco retrofits from the 2015-2019 rush often went up over chalky, moisture-laden walls. The foam delaminates in sheets. We strip to substrate, let the wall dry to 15% moisture content verified with a pin meter, then reapply with a compatible primer. No primer, no warranty on our work.
- Demilec SEALECTION Agribalance density drift in thick lifts. This medium-density open-cell is specified in 5.5″ lifts, but installers chasing speed in the Rancho Los Cerritos area sometimes shot 8″+ in one pass. The core doesn’t cure fully, leaving a cheesy, low-R layer hidden inside. We core-sample with a 2″ hole saw, measure density with a postal scale, and document the failure for your records. Replacement lifts are shot to spec, period.
- HFO Pro off-ratio curing from aged iso drums. Demilec’s HFO systems are sensitive to A-side shelf life; drums sitting in a Long Beach warehouse through two summers often yield off-ratio foam that crumbles at the cut. We check the lot dates on any touch-in work, and we keep fresh iso in climate-controlled storage. When we patch, the chemistry matches.
Our Demilec Home Energy Audit Process

- 1
Call and schedule. A live person answers, asks square footage, year built, and what’s driving the call. We book a 2-hour window and text when the technician is en route.
- 2
Blower-door test first. We pressurize the house to 50 pascals and record CFM50 - the single number that tells us how much conditioned air is escaping. In Long Beach’s 1920s bungalows, we often see 3,500+ CFM50 before any work is done.
- 3
Thermal imaging and physical inspection. Our FLIR camera maps missing or degraded Demilec foam, especially at top plates and knee walls where Long Beach’s coastal humidity finds gaps. We borescope what we can’t see directly.
- 4
Insulation depth and density check. We probe existing Demilec with a depth gauge and core-sample where density is suspect. R-value is calculated from thickness and product spec, not guessed.
- 5
Duct leakage test if indicated. A Duct Blaster pressurizes the HVAC system to 25 pascals; we quantify leakage to outside and map it against the thermal image. Ducts buried in Demilec foam are especially costly to access later, so we flag this now.
- 6
Written report and price. You get a one-page summary with blower-door number, thermal images, R-value readings, air-sealing locations, and a flat price for any recommended work. No price, no work starts. Haven Standard Clause 1.
What Demilec Home Energy Audit Costs in Long Beach
| Service | Typical Range | What Moves It |
|---|---|---|
| Basic home energy audit (blower door + thermal imaging) | $280 - $380 | Home size, accessibility of attic/crawl space |
| Audit with duct leakage testing | $420 - $520 | Number of HVAC systems, duct accessibility |
| Demilec-specific failure investigation (core sampling, borescope) | $180 - $280 add-on | Number of suspect locations, lift thickness |
| Written remediation scope with photo documentation | Included | Part of every audit |
Homes in Belmont Shore and Naples Island with multiple HVAC zones or conditioned attics run toward the higher end. Single-story bungalows in Wrigley typically hit the lower range. We do not charge for the report or the photo record. Bring us a competing written estimate and we’ll give you a free second opinion, line by line. Call (424) 415-7031 for your exact written price.
Why Long Beach Homeowners Call Topside Attic Insulation Long Beach for Demilec Work

We’ve been independently owned and operated under The Haven Standard since 2016, and in that time we’ve sealed and insulated 9,000+ homes - every one with a written price first and a documented record at the end. Wes Okafor learned this trade at Olive-Harvey College in Chicago, where the building-science program put a blower-door in his hands before he ever touched insulation. That shows in how we work: we measure existing R-values before quoting, publish before-and-after blower-door numbers on every air-sealing job, and hand you a one-page report with pre-install depths, post-install depths, and every sealing location we addressed.
Our 365-Day Done Right Promise covers all completed work. Our technicians are background-checked and uniformed. Calls are answered by a live person, 24/7, because voicemail loops measured in business days are not acceptable. We also service Reflectix radiant barriers when they’re part of your envelope assembly. No proprietary lock-in, no upsell theatre, no exceptions to the written price rule.
FAQs
No. Demilec’s product warranty covers material defects, not who inspects it. As an independent Demilec service provider, we document our findings with photos and core samples that can actually support a warranty claim if we find a manufacturing issue. Demilec’s warranty does not require factory-authorized inspection. If you’re within the warranty period and we find a product defect, we flag it in our report so you have documentation for your claim. Call (424) 415-7031 and we’ll review your install date and product line.
We source Demilec products directly through authorized distributors for patch and touch-in work where color and chemistry matching matter. For larger removals and replacements, we may recommend equivalent-performance products from Icynene, Johns Manville, or Knauf depending on your specific assembly and budget. We never use “equivalent” products without explaining the trade-off in R-value, vapor permeance, and fire rating. The choice is documented in your written scope before work starts.
Localized failures - shrinkage at a rim joist, a vent block, a delaminated patch - are repairable if the surrounding foam is sound and properly adhered. We core-sample and pull-test to verify. Widespread off-ratio curing, moisture-compromised foam, or density drift through multiple lifts usually means removal and reapplication. Our audit gives you the data: density readings, adhesion test results, moisture content, and a line-item price for each scenario. Most Long Beach homeowners with post-2015 Demilec installs fall into the repairable category. Call (424) 415-7031 for a written assessment.
Same-day and next-day availability for Long Beach residents, including weekends. Emergency scheduling applies if you’re experiencing active moisture intrusion or HVAC failure tied to insulation performance. We text technician ETA the morning of. No callback windows, no “sometime between 8 and 5.”
A one-page written report with your blower-door number (CFM50), thermal images with temperature annotations, insulation depth readings by location, any core-sample density results, and a flat written price for recommended work with scope and warranty terms. Photos are delivered digitally within 24 hours. This is the Documented Photo Record included on every visit, not available on request. You own the file.
