Demilec Home Energy Audit in West Hollywood: What to Know First

A Demilec home energy audit in West Hollywood typically takes 2 to 3 hours and gives you a room-by-room map of where your spray foam is underperforming, where air is moving through your building envelope, and exactly what it will cost to fix. We charge a flat rate for the audit itself, and if you hire us for the repair work, we apply that fee toward the job. This page is for homeowners who have Demilec spray foam insulation in their walls, attic, or crawl space and want to know if it’s actually doing what it should. Call (213) 527-4062 and Walt or one of our techs will walk you through what to expect.

How Demilec Products Fail - and How We Fix Them

Spray foam is a great product when it’s installed right and conditions cooperate. But Demilec foam, like every spray foam, has specific ways it degrades over time, especially in West Hollywood’s climate. Here’s what we find on audit after audit.

• Heatlok HFO shrinkage at the roofline. Heatlok HFO is a closed-cell foam, and when it’s sprayed too thick in one pass or applied to a dusty or damp substrate, it can shrink slightly as it cures. In West Hollywood attics, where daytime temperatures swing 30 degrees between morning and afternoon, that shrinkage shows up as hairline gaps where the foam meets the rafters. That’s a conditioned air leak you can’t see without a thermal camera. We document it, then re-foam the gap or apply a compatible sealant depending on the size.
• Sealection 500 open-cell saturation in crawl spaces. Sealection 500 is open-cell, which means it breathes. That’s fine in a wall cavity, but in a West Hollywood crawl space with any moisture history, it can hold water like a sponge. We regularly pull back wet Sealection 500 in homes near the Hollywood Hills where groundwater or poor drainage is a factor. The audit shows the moisture with thermal imaging, and we talk honestly about whether the foam should stay or come out.
• Polar Foam off-gassing smell that won’t go away. Demilec’s Polar Foam line, especially older formulations, can have a persistent chemical odor if the A and B components weren’t mixed at the right temperature or ratio at installation. Homeowners live with it for years thinking it’s normal. During an audit, we’ll identify whether the smell is coming from under-cured foam and recommend the most practical fix, which is often removal and a re-spray with a product better suited to the space.
• Gaps around window and door frames where Demilec foam was never installed. This one isn’t a Demilec failure, it’s an installer failure. In West Hollywood’s older Spanish-style homes and 1940s bungalows, we find plenty of walls where the original contractor skipped the window frames entirely or used a cheap one-part can foam that crumbled. The blower door tells us exactly how much air is moving through those gaps, and we re-foam them properly.
• Demilec foam pulling away from metal studs in condo conversions. West Hollywood has a lot of converted commercial buildings, and those metal studs expand and contract differently than wood. Demilec foam applied to metal studs without proper surface prep can delaminate over time, leaving a vertical air channel behind the drywall. That’s the kind of thing that only shows up with an infrared camera and an experienced operator who knows what he’s looking at.

Our Demilec Home Energy Audit Process

Here’s what happens when you call us about a Demilec home energy audit in West Hollywood.

1. 1
   You call (213) 527-4062. A live person answers. We ask basic questions about your home: square footage, year built, where your Demilec foam is installed, and what problems you’ve noticed. No script, no hold music.
2. 2
   We schedule the audit. Most West Hollywood audits happen within the same week. We show up in uniformed trucks with background-checked techs, and you’ll know exactly who’s walking through your door because we’ve already told you their names.
3. 3
   Blower door test goes in first. We depressurize the house and measure total air leakage. This gives us a baseline number that tells us how your Demilec foam is performing compared to what a tight envelope should look like.
4. 4
   Thermal imaging walks the property. We scan every wall, ceiling, and floor with an infrared camera. This shows us temperature anomalies, which in spray foam homes means shrinkage, delamination, or missed areas. We also inspect visible foam in attics and crawl spaces for physical signs of failure, which tells us things the blower door can’t.
5. 5
   Duct leakage test if you have forced air. Demilec foam in the attic is only as good as the duct seals below it. We pressure-test your ducts and document any leakage.
6. 6
   You get a written report. Photos, thermal images, the blower door number, and a prioritized list of fixes with honest pricing. If the fix is something we can do, we tell you exactly what it costs. If it’s not, we tell you who to call. Either way, the report is yours to keep, and there’s no obligation to hire us for the repair.

What Demilec Home Energy Audit Costs in West Hollywood

A standalone Demilec home energy audit in West Hollywood runs $295 to $495 depending on square footage and how many systems we’re testing. Smaller condos and single-story homes fall on the lower end. Homes over 2,500 square feet or with multiple HVAC zones land on the higher end. If you hire us for the repair work afterward, we credit the full audit fee toward that job. Here’s what common scenarios look like:

• Blower door test only: $195
• Full audit with thermal imaging (up to 2,000 sq ft): $350
• Full audit with thermal imaging (2,000 to 3,500 sq ft): $450
• Full audit plus duct leakage test: Add $95
• Audit plus crawl space moisture inspection: Add $75

What moves the price is access. If your attic is tight or your crawl space is low clearance, it takes us longer and we may need to bring in a second tech. No trip charge inside Los Angeles County, and if you have a written estimate from another contractor, we’ll give you a free second opinion. That includes Demilec audit work. Call (213) 527-4062 and we’ll give you an exact number over the phone.
