We provide independent Demilec attic cleaning and rodent proofing in Tustin, typically completing most jobs in one to two days with a written price locked in before any work starts. Most Demilec attic restoration projects in Tustin run between $2,800 and $6,400 depending on contamination level, accessible square footage, and whether the Demilec foam needs selective removal or perimeter sealing.

How Demilec Products Fail - and How We Fix Them

• Demilec Heatlok HFO Pro - rodent tunneling at the foam-to-deck interface. The closed-cell structure is dense, but rodents exploit the gap where HFO Pro meets roof sheathing in Tustin’s warmer attics. The foam doesn’t compress; they go around it. We remove contaminated sections, seal the gap with compatible polyurethane caulk, then install galvanized exclusion mesh before restoring insulation.
• Demilec Sealection 500 - urine saturation in low-density open-cell applications. Sealection 500 absorbs moisture and organic matter when rodents nest directly on it. The odor penetrates the cell structure and recirculates through HVAC returns in homes near Peters Canyon. We spot-remove affected foam using controlled cutting, apply enzymatic decontamination to the substrate, and replace with new Sealection 500 or recommend a density upgrade if the infestation was severe.
• Demilec Heatlok XT - mechanical damage from trapped rodents chewing exit paths. XT’s higher compressive strength means rodents can’t burrow through it easily, so they chew laterally along joist bays. This creates channels that bypass the thermal barrier. We map the damage with thermal imaging, excise the compromised channels, and backfill with OEM Heatlok XT to maintain the original R-value and fire rating.
• Demilec Agribalance - degradation from combined rodent oils and Tustin’s summer attic heat. Agribalance’s bio-based polyol content is more susceptible to hydrolysis when saturated with rodent sebum and urine in attics that hit 140°F in August. The foam surface develops a tacky, degraded layer. We shave to sound foam, verify adhesion with a pull test, and respray only after full substrate decontamination.
• Demilec open-cell at top plates - rodent highway creation. When open-cell Demilec is used at the attic perimeter, the irregular surface gives rodents purchase to traverse wall top plates between units in Tustin’s townhome clusters near the District. We trim back the foam, install continuous metal flashing as a physical barrier, then respray with a smooth-skin pass that eliminates grip points.

Our Demilec Attic Cleaning & Rodent Proofing Process

1. 1
   Call and scope. A live person answers at (657) 286-7673. We schedule a site visit, usually within 48 hours in Tustin.
2. 2
   Blower-door baseline and thermal survey. We pressurize the house to measure CFM50 leakage, then run a thermal camera to locate compromised Demilec sections and active rodent paths. You get both images in your Documented Photo Record.
3. 3
   Written price and material spec. Before any work starts, we deliver a flat price, a written scope identifying your Demilec product line, and a parts list noting OEM Demilec foam or warranty-compatible alternatives. No work begins without your signature.
4. 4
   Exclusion first, then remediation. We seal all entry points larger than 1/4 inch with galvanized steel, concrete, or copper mesh - rodent-proof materials that outlast foam repairs. Then we remove contaminated insulation and foam, HEPA-vacuum the deck, and apply enzymatic decontamination.
5. 5
   Foam restoration and air sealing. We reinstall or respray Demilec product to match original specifications, seal top plates and penetrations, and run a post-work blower-door test to verify we didn’t degrade the envelope.
6. 6
   Documentation and 365-Day Done Right Promise. You receive before-and-after blower-door numbers, thermal images, a written R-value report, and the Haven Standard warranty card. Under Haven Standard: Arrive on schedule, you get a named technician and a text when they are on the way.

What Demilec Attic Cleaning & Rodent Proofing Costs in Tustin

Demilec-specific costs run higher than generic foam when we use OEM respray material to preserve warranty coverage. We also service Reflectix radiant barrier systems when they’re part of the same attic assembly. Call (657) 286-7673 for an exact quote - estimates are free, and we provide a Free Second Opinion on any written estimate you’ve already received.

Why Tustin Homeowners Call Topside Attic Insulation Tustin for Demilec Work

We’ve logged a lot of time in Tustin Legacy, where the post-redevelopment housing stock made blower-door testing a baseline step rather than an afterthought. Wes Okafor and our crew know the difference between Heatlok HFO Pro and Sealection 500 by sight and density, and we stock the tooling to cut and respray both without calling in a secondary trade. Our 365-Day Done Right Promise applies to every Demilec restoration - if the rodents return through our exclusion work, we return. The Haven Standard requires a written price before any work starts and a Documented Photo Record when we leave, so you have paper to hand a future buyer or an HVAC contractor. We also service Reflectix systems when they’re integrated with Demilec foam in the same attic.

Seal the leaks first. Then insulate. The R-value on the bag means nothing if conditioned air is moving through the gap around that recessed can.
