Demilec Attic Cleaning & Rodent Proofing Nationwide | Walt’s Insulation

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

Demilec attic cleaning and rodent proofing in Anaheim typically runs $1,200 to $3,800 depending on attic size, contamination level, and how much exclusion work is needed. Most Demilec homes we service are back to clean, sealed, and rodent-free within one to two days. We’re an independent Demilec service provider, not a manufacturer-authorized shop, which means we fix what’s actually wrong without warranty games or upsell pressure.

How Demilec Products Fail - and How We Fix Them

Demilec makes solid insulation products, but no foam is rodent-proof on its own. Here’s what we see in Anaheim attics, week after week.

• Heatlok HFO and rodents tunneling through open-cell foam. We regularly pull back Heatlok HFO in older Anaheim ranch houses near Lincoln Avenue and find rat tunnels bored straight through the foam. Rodents don’t eat it, but they’ll carve paths through open-cell material to reach warm air near ducting. Our fix starts with full removal of the compromised sections, then sanitizing, then exclusion work at every entry point before new foam or fill goes in.
• APX series and nesting cavities at soffit intersections. Demilec’s APX closed-cell line holds up well structurally, which means rats can’t tunnel through it as easily. What we find instead is nesting activity in the gap where APX foam meets soffit vents. In Anaheim’s older neighborhoods like the Colony, original wood soffits warp over time and leave gaps. We seal those with steel mesh and foam backer before anything else.
• Sealection 500 and urine saturation in cathedral ceilings. Sealection 500 is common in Anaheim homes with vaulted ceilings. When rodents nest above it, urine soaks into the open-cell foam and the smell penetrates drywall. You can’t scrub that out. The fix is cutting out the saturated sections, treating the framing, and re-foaming. We’ve done this in homes near Pearson Park where the smell was the only sign, no scratching at all.
• Heatlok Soy and dust-attracted droppings near recessed lights. Soy-based Demilec foam has a faint odor that can attract rodents investigating for food. Once they’re in, droppings collect around can lights and junction boxes. We clean those areas with HEPA vacuums and enzyme treatments, then rodent-proof every can light penetration with rated covers.
• Mixed Demilec and fiberglass jobs where the transition point fails. Plenty of Anaheim homes have Demilec foam on the roofline and fiberglass batts on the attic floor. Rodents travel along that transition line. We find tunneled batts and foam chewed at the seam. Our crews rebuild that transition with exclusion mesh so the rodents don’t get a second chance.

Our Demilec Attic Cleaning & Rodent Proofing Process

Every Demilec attic job follows the same six steps, whether it’s a small cleanout or a full decontamination and re-insulation.

1. 1
   Call and walkthrough. You call (657) 214-8224, we schedule a visit, and one of our background-checked techs inspects the attic, takes photos, and gives you a written quote before any work starts.
2. 2
   Entry point mapping. We don’t just look inside. We walk the roof line, check eaves, vents, pipe penetrations, and gable ends to find every way rodents are getting in. In Anaheim, roof rats love utility line gaps and overhanging trees.
3. 3
   Contamination removal. We remove feces, nesting material, and compromised insulation, including saturated or tunneled Demilec foam sections. HEPA vacuums and full PPE every time.
4. 4
   Sanitizing and deodorizing. We treat affected framing and surfaces with enzyme-based cleaners that neutralize urine and pheromone trails, the stuff that makes rodents want to come back.
5. 5
   Exclusion and proofing. Every entry point gets sealed with steel mesh, foam backer, and corrosion-resistant hardware. If you want new Demilec foam installed, we’ll match the existing product type. If you’re switching brands, we also work with Owens Corning, Rockwool, Johns Manville, and Reflectix.
6. 6
   Final inspection and the Done Right Promise. We walk you through what we did, show you the photos, and stand behind the work for life. If it’s not done right, we make it right.

We’ve been doing this since 2000, and we’re the one down the road, not an 800 number.
