Demilec Home Energy Audit Nationwide

Demilec Home Energy Audit in Newport Beach: What to Know First

We provide independent Demilec home energy audit in Newport Beach, typically completing the full diagnostic and written report within a single visit. Most audits run between $280 and $520, depending on home size and whether duct leakage testing is included. We are not affiliated with or authorized by Demilec; we are an independent service provider who works on the Demilec systems already installed in your home.

This page is for Newport Beach homeowners who have Demilec spray foam or insulation products and need to understand why their energy bills are climbing, which rooms won’t hold temperature, or whether the original installation was done correctly. If you’re seeing uneven performance from a Demilec system installed between 2010 and 2020, you’re not alone. Call (657) 261-8265 to schedule. We answer live, 24/7.

How Demilec Products Fail - and How We Fix Them

• Demilec Heatlok HFO High Lift shrinkage in coastal attics. The HFO blowing agent can contract more than expected in Newport Beach’s marine-layer temperature swings, especially in unvented attics above the Balboa Peninsula where morning fog keeps sheathing damp until noon. We measure the gap with thermal imaging, then inject compatible open-cell foam to bridge the void rather than tear out and restart.
• Demilec Sealection 500 density degradation in hot roof assemblies. Homes in the hills above Corona del Mar with dark tile roofs see attic sheathing hit 140°F regularly. Sealection 500 can lose nominal density over 8-10 years in these conditions, reducing its effective R-value. We core-sample the foam, test with a calibrated die, and specify either targeted reapplication or a hybrid approach with rigid board.
• Demilec Heatlok XT missed adhesion on OSB with factory-applied sealant. Some Newport Beach tract builds from 2015-2018 used OSB with a proprietary edge sealant that interfered with Heatlok XT’s substrate bond. The foam looks intact but delaminates in sheets. We find this with a pull-test probe and reattach using a primer system that doesn’t require full removal.
• Demilec Agribalance off-ratio application in crawl spaces. Agribalance’s soy-based polyol is more sensitive to ambient moisture during application than petroleum-based alternatives. In Newport Beach crawl spaces with seasonal groundwater rise, off-ratio foam turns chalky and crumbles. We excavate the failed material, dry the substrate with targeted dehumidification, and reapply only after moisture readings stabilize below 19%.
• Demilec open-cell foam air sealing compromise at top plates. Even well-installed Demilec open-cell can leave the critical wall-to-ceiling junction leaky if the crew didn’t follow with dedicated air sealing. We run a blower-door test - a pressurization reading that shows, in one number, how much conditioned air your building envelope is losing - then seal with compatible one-part foam and acrylic tape before any insulation discussion.

Our Demilec Home Energy Audit Process

1. 1
   Call intake and scheduling. A live person answers. We confirm your Demilec product line if you know it, home age, and the symptoms you’re seeing. We schedule for a specific arrival window, not an all-day hold.
2. 2
   On-site diagnostic. Wes Okafor or a trained technician arrives uniformed and background-checked. We run a blower-door test to establish baseline air leakage in CFM50, then thermal imaging to map thermal bypasses and insulation voids. For homes with ductwork in conditioned space, we add a duct blaster test.
3. 3
   Demilec-specific inspection. We identify your Demilec product line, check for the failure modes above, and photograph condition. If core sampling is needed, we explain why and show you the sample.
4. 4
   Written scope and price. Before any work starts, you receive a flat price, written scope, and written warranty. Haven Standard Clause 1: no work begins without it. This is not an estimate that shifts later.
5. 5
   Execution and documentation. We complete the agreed work, run a post-repair blower-door test, and publish the before-and-after numbers. You receive a Documented Photo Record of all work areas. The 365-Day Done Right Promise applies.
6. 6
   Cleanup and closeout. We remove all debris, verify your thermostat readings are tracking correctly, and leave the written record with you. No callback windows measured in business days.

What Demilec Home Energy Audit Costs in Newport Beach

What moves the price: home square footage, accessibility of attic or crawl space, whether the original Demilec installation was done as part of a new build or retrofit, and whether we find code compliance issues that need addressing. Homes on Lido Isle with tight lot lines and no driveway access take longer to stage; we account for this in the written price, not as a surprise add-on.

Every audit includes a Free Second Opinion on any written estimate you’ve already received. Bring us a competing quote and we’ll read it with you. Call (657) 261-8265 for your written price.

Why Newport Beach Homeowners Call Topside Attic Insulation Newport Beach for Demilec Work

We’ve sealed and insulated over 9,000 homes since 2016, every one with a written price before work started and a documented record when the crew left. On Demilec jobs, we don’t guess at why your foam is underperforming; we test, sample, and specify based on what the building actually shows us.

Our materials come from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber, plus Reflectix when radiant barrier is the right supplement. No proprietary lock-in means we specify what works for your specific assembly, not what moves our inventory.

The 365-Day Done Right Promise covers all completed work. Calls are answered by a live person, 24/7. Under Haven Standard: Arrive on schedule, you get a named technician and a text when they are on the way.

Wes Okafor’s crew has run blower-door tests on homes from the Balboa Peninsula to the hills above Corona del Mar. He’ll tell you straight: seal the leaks first. Then insulate. The R-value on the bag means nothing if the air is moving freely around it.
