Demilec Attic Cleaning & Rodent Proofing in Inglewood: What to Know First

Demilec attic cleaning and rodent proofing in Inglewood typically runs $1,200 to $4,800 depending on attic size, contamination level, and how much exclusion work the structure needs. We complete most Demilec attic jobs in one to two days, and every quote is upfront with no surprise line items. If rodents have gotten into your Demilec foam insulation, the fix isn’t just trapping, it’s removing the soiled material, sanitizing the space, and sealing every entry point so they can’t come back.

How Demilec Products Fail - and How We Fix Them

• Heatlok HFO open-cell foam absorbs rodent urine and holds it. Demilec’s Heatlok HFO line is open-cell, which means it’s breathable and vapor-permeable. That’s fine for thermal performance, but when rats or squirrels nest against it, urine soaks into the foam cells and the odor won’t air out. We cut out the contaminated section, sanitize the decking beneath, and reapply compatible foam after the exclusion work is done.
• Closed-cell Demilec lines hide rodent tunnels until the damage is extensive. Demilec’s closed-cell products, including Heatlok HFO Pro and certain Sealection variants, are rigid enough that rodents can bore through them without leaving visible surface damage. By the time a homeowner notices droppings in the garage, there’s often a network of tunnels behind the foam. Our techs probe the surface systematically during every Demilec attic inspection, because we’ve learned the damage usually isn’t where the droppings are.
• Demilec foam pulled away from roof decking creates ready-made rodent runs. In Inglewood’s coastal temperature swings, improperly installed Demilec foam can delaminate from the sheathing, leaving a gap just big enough for a rat to travel. We see this most often in attics insulated five to ten years ago. The fix is removing the delaminated section, addressing whatever caused the adhesion failure, and re-foaming with proper substrate prep.
• Rodents chew through Demilec’s intumescent coatings when they’re applied too thin. Demilec products are engineered with fire-performance properties, but those properties don’t stop rodent teeth. In attics where the thermal barrier or ignition barrier was sprayed at minimum thickness, squirrels can gnaw through in a single season. We document the damage for you and can match the coating system when we restore the area.
• Old Demilec foam installed before current code often hides pre-existing rodent entry points. Many Inglewood homes had Demilec foam installed years ago by crews that never sealed the soffit-to-wall transition or the plumbing penetrations first. The foam covers the gaps, but rodents chew through around pipe chases and wiring holes. Our exclusion process maps every penetration before foam goes back in, so we’re not just repeating the original installer’s mistake.

Our Demilec Attic Cleaning & Rodent Proofing Process

1. 1
   Attic assessment and Demilec condition check. We inspect the foam type, thickness, adhesion, and any rodent activity. We also check the roof decking, soffit vents, and gable ends for entry points.
2. 2
   Contamination mapping. We identify every section of Demilec foam that’s been soiled or tunneled. You get a clear scope of what’s coming out and why, no vague “we’ll see when we get in there.”
3. 3
   Removal and bagging. Contaminated foam is cut out, double-bagged, and removed through a sealed chute, not tossed through your hallway. We run HEPA filtration during the removal.
4. 4
   Sanitizing and decontamination. The decking and any remaining structure get treated with an enzyme-based deodorizer that breaks down urine proteins. Bleach doesn’t do it. The enzymes do.
5. 5
   Rodent exclusion. Every penetration is sealed with rodent-proof materials: steel mesh, flashing, and foam where appropriate. This is the step that determines whether the problem stays solved.
6. 6
   Foam restoration and testing. We reapply Demilec-compatible foam where removal happened, then verify the seal with a smoke test or thermal scan before we call the job done. Every Demilec attic job carries our 90-Day Done Right Promise.

What Demilec Attic Cleaning & Rodent Proofing Costs in Inglewood

What moves the price in Inglewood is attic access (crawl-hatch vs. walk-in), how much Demilec foam has to come out, and how many entry points need sealing. Homes near Morningside Park or the older blocks around La Brea and Florence tend to have more original construction gaps to close. You’ll get a fixed quote before work begins, and remember: $50 off any repair over $250, plus a permanent 5% discount for seniors and veterans.

Why Inglewood Homeowners Call Warmline Insulation Co. for Demilec Work

We’ve been in attics across Inglewood since 2011, from the neighborhoods around SoFi Stadium to the streets off Centinela and Arbor Vitae. Neil Ashford started this company after seeing too many houses where insulation was an afterthought, and that’s why we treat Demilec foam restoration as a building-science problem, not a pest control side job. Our techs are background-checked and uniformed, most Demilec attic jobs are done in a single visit, and if something isn’t right, the 90-Day Done Right Promise means we make it right. We also service Reflectix radiant barriers, so if rodents got into your attic’s reflective insulation along with the foam, one crew handles both. One call, one crew, no juggling three contractors.
