This page is for Inglewood homeowners who have Demilec insulation that’s failing, saturated, pest-compromised, or simply underperforming. Whether it’s Heatlok HFO in an attic that never cured right or Sealection 500 in a wall cavity that’s shrinking and pulling away from studs, we’ll explain what went wrong, what it takes to fix it, and what it should cost before you commit to anything.

How Demilec Products Fail - and How We Fix Them

Demilec makes quality insulation. But every product has a lifespan, and in Inglewood’s coastal climate with its summer heat and winter damp, certain failure patterns show up repeatedly. Here’s what we see on Demilec jobs and how we address each one.

• Heatlok HFO shrinkage and pull-away. Heatlok HFO is a closed-cell spray foam that should bond permanently to sheathing and studs. When installed during high humidity or at incorrect temperatures, the foam can shrink and pull away from framing, leaving air gaps. We remove the compromised foam with hand tools and pneumatic scrapers, then reinstall a properly conditioned Demilec product or a material that matches the application.
• Sealection 500 water retention in wall cavities. Sealection 500 is an open-cell, water-blown foam. If a roof or plumbing leak saturates it, it holds moisture like a sponge and can lead to mold inside wall cavities. In Inglewood homes with older plumbing, we regularly find Sealection 500 that looks fine from the outside but is soaked behind the drywall. We remove the affected foam, dry the cavity, and replace it with closed-cell Demilec Heatlok HHO or a comparable product that won’t retain water.
• Contaminated Demilec foam from rodent activity. If rats or squirrels get into an attic, Demilec foam becomes a nesting material target. The foam gets tunneled through, saturated with droppings, and becomes a health concern. Our removal process includes full HEPA vacuuming, foam extraction, and sanitizing before we install new insulation and rodent-proof the space.
• Vermiculite mixed with old Demilec installations. In older Inglewood homes near Morningside Park and the neighborhoods around Century Boulevard, we sometimes find vermiculite tucked beneath a newer Demilec spray foam layer. Vermiculite from certain mines can contain asbestos, so we never disturb it without proper testing and containment protocols. We coordinate with certified labs for testing and follow all state removal requirements.
• Off-ratio Demilec foam from original installation errors. Spray foam must mix at a precise chemical ratio. When an installation contractor runs low on one component or doesn’t heat the barrels properly, the foam never fully cures and remains tacky or emits an ammonia-like odor for months. This is one of the most common Demilec complaints in Inglewood homes built or renovated during the last five years. We remove the off-ratio foam entirely and reinstall a correctly mixed product. This isn’t a repair job; it’s a full removal and replacement, and it’s the only way to eliminate the odor.

Our Demilec Insulation Removal & Replacement Process

Every Demilec job in Inglewood follows a clear sequence. Here’s what happens from the first call to the final walkthrough.

1. 1
   Call and scheduling. You call (424) 622-5846. A live person answers and we schedule a visit that works for your calendar. Same-day and next-day appointments are available for urgent cases like water-saturated foam or persistent odor.
2. 2
   On-site diagnostic. Neil Ashford or one of our background-checked technicians examines the Demilec foam in place. We look for shrinkage, moisture, contamination, off-ratio conditions, and R-value degradation. We use thermal imaging to map exactly where insulation has failed.
3. 3
   Removal plan and upfront pricing. We document everything, then hand you a written quote before any work begins. The price covers removal, disposal, surface preparation, and new insulation. No change orders, no surprise fees.
4. 4
   Removal and disposal. We extract the Demilec foam or injection insulation using the right tools for the material and the space. Foam is bagged and removed. If we find contamination or moisture, we address it before the new insulation goes in. We follow all California waste-handling requirements.
5. 5
   Replacement installation. New Demilec product or the replacement material best suited to your home’s needs goes in. If we’re replacing open-cell with closed-cell, we’ll explain why and what it does to your energy performance.
6. 6
   Testing and the 90-Day Done Right Promise. We verify the installation, check for air leaks, and deliver the final walkthrough. If anything isn’t right within 90 days, Warmline Insulation Co. makes it right. That’s a written commitment.
