This page is for Los Angeles homeowners who have Demilec open-cell or closed-cell spray foam in their attic, walls, or crawl space and need to know whether it’s performing as specified. Wes Okafor and our crew have audited hundreds of Demilec installations across the metro, from original builds in Playa Vista to retrofits in Silver Lake where the product was specified by a prior contractor.

How Demilec Products Fail - and How We Fix Them

• Demilec SEALECTION 500 overspray gaps at top plates. In Los Angeles ranch homes with raised heel trusses, this open-cell foam often misses the narrow junction between the top plate and the drywall ceiling, leaving a thermal bypass that the blower-door test catches at 3,500 CFM50 or higher. We remove the compromised section, seal the gap with compatible single-component foam, and re-blow to the specified depth.
• Demilec Heatlok XT shrinkage at rim joists. This closed-cell product can pull away from concrete or sill plates in crawl spaces during the first two heating seasons, especially in homes near the coast where marine layer moisture slows full cure. We cut back the separated foam, treat the substrate with a compatible primer, and reapply to the original R-value specification.
• Demilec HFO Pro spray inconsistencies in wall cavities. When the A-side temperature drifts during application, this newer formulation can develop density variations that read as cold spots on thermal imaging. We core-sample suspect areas, verify density with the manufacturer’s published range, and either add a flash coat or remove and reapply depending on the variance.
• Demilec Agribalance degradation from rodent activity. This bio-based open-cell foam is attractive to nesting rodents in Los Angeles hillside homes where roof rat pressure is high. We remove contaminated sections, install rodent-proofing at access points, and replace with a non-cellulosic alternative if the homeowner prefers.
• Demilec SEALECTION 500 moisture trapping in unvented assemblies. When this open-cell foam is installed on the underside of roof sheathing without a proper vapor profile, Los Angeles summer sun drives moisture inward that the foam absorbs. We test with a moisture meter, install a vented channel or specify a vapor-closed alternative, and document the assembly correction for the homeowner’s records.

Our Demilec Home Energy Audit Process

1. 1
   Call and scheduling. A live person answers, 24/7. We book a two-hour window and text when the technician is en route.
2. 2
   Blower-door test. We depressurize the house to 50 Pascals and record the CFM50 reading - the baseline that every later decision refers back to.
3. 3
   Thermal imaging and visual inspection. We scan all Demilec surfaces for anomalies, then probe with a moisture meter and core sampler where indicated. We photograph every finding.
4. 4
   Written scope and price. Before any repair, you get a flat price, a written scope, and a written warranty. No work starts without it. Haven Standard Clause 1.
5. 5
   Air sealing first, then insulation correction. Seal the holes first. Then measure the R-value. In that order. We never add product over an unsealed assembly.
6. 6
   Final blower-door test and documentation. We run the test again, hand you the before-and-after numbers, the installed R-value, the product data sheets, and the photo record.

What Demilec Home Energy Audit Costs in Los Angeles

Price moves with access difficulty (crawl space vs. walk-up attic), the square footage of Demilec involved, and whether we need to bring in scaffolding for vaulted ceilings common in Los Angeles mid-century builds. We also service Reflectix radiant barrier systems where those were paired with Demilec in hybrid assemblies.

Why Los Angeles Homeowners Call Topside Attic Insulation Los Angeles for Demilec Work

We are an independent Demilec service provider, not affiliated with or authorized by the manufacturer. That independence means we specify what the assembly actually needs, not what a brand protocol requires.

Our 365-Day Done Right Promise applies to every Demilec correction we make. If it’s not done right, we make it right. We publish before-and-after blower-door numbers on every applicable job so you can verify the performance change you paid for. Our technicians are background-checked and uniformed; the person who audits your Demilec installation has measured, air-sealed, and blown attic assemblies for years, not months. And we source materials from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber - no proprietary lock-in, so the solution fits the house rather than the supplier’s inventory.
