How Demilec Products Fail - and How We Fix Them

Demilec’s open-cell and closed-cell spray foam lines behave differently in Whittier’s dry, hot-summer climate than in humid regions, and we’ve seen enough of them to know where to look first. Here’s what we find on Demilec jobs around Whittier:

• Heatlok HFO High Lift shrinkage at roof decks. The HFO blowing agent can pull away from rafter bays in unvented attics when seasonal temperature swings exceed 40°F, which happens regularly in Whittier from May through October. We map the gaps with thermal imaging, remove the failed sections, and reapply only after sealing the thermal bypasses that caused the uneven expansion in the first place.
• Heatlok XT adhesive failure on stucco substrates. In Whittier’s older Spanish Colonial and Ranch-style homes, the XT formulation can delaminate from exterior walls where previous contractors skipped the primer coat or applied over chalking stucco. We test adhesion with a pull gauge, strip to substrate, and reapply with the correct primer sequence - documented with photos.
• Demilec open-cell moisture retention in crawl spaces. Open-cell foam below grade in Whittier’s clay-heavy soils - common in the Michigan Park area - traps soil moisture against rim joists. We never leave open-cell in a crawl space; we remove it, install a proper vapor barrier, and replace with closed-cell or a hybrid system depending on the moisture load.
• Heatlok HFO High Lift over-application in 1950s California bungalows. Contractors sometimes spray HFO High Lift too thick in a single pass to speed the job, causing internal cracking that isn’t visible until the blower-door test shows unexpected leakage. We core-sample the foam, measure density, and remove and reapply in lifts no thicker than 2 inches per pass.
• Demilec top-plate gaps missed during original installation. Even quality foam installers sometimes skip the critical seam between top plates and drywall, especially in Whittier’s split-level homes where access is tight. We seal these with backer rod and acoustic sealant before any insulation touches the attic floor - seal it first, then cover it, the insulation is not the fix, it’s the finish.

Our Demilec Home Energy Audit Process

1. 1
   Call and scheduling. A live person answers, confirms your Demilec product line if you know it, and books a 2-hour window. You’ll get a text when the technician is en route.
2. 2
   Visual and thermal inspection. We photograph every Demilec-labeled surface, run a FLIR scan to find subsurface gaps, and note any discoloration, shrinkage, or odor that indicates chemical off-gassing or moisture intrusion.
3. 3
   Blower-door test. We pressurize the house to 50 Pascals - the standard CFM50 reading - and compare against the IRC target for your home’s conditioned floor area. In Whittier, a 1,600-square-foot 1960s ranch typically leaks 3,500-5,000 CFM50 before sealing.
4. 4
   Written scope and pricing. Under Haven Standard Clause 1, you get a flat price, written scope, and written warranty before anyone lifts a tool. No exceptions.
5. 5
   Air sealing first, then insulation. We seal top plates, can lights, and penetrations, then re-run the blower door to verify. On applicable jobs, we publish the before-and-after numbers so you can see the performance change you paid for.
6. 6
   Documented Photo Record and 365-Day Done Right Promise. You receive photos, readings, and warranty documentation before the crew leaves. If it’s not done right, we make it right.

What Demilec Home Energy Audit Costs in Whittier

Homes in Whittier’s hilly northern zones - near Hellman Park - often run 15% higher due to steep roof pitches and limited attic access.
