Demilec Attic Cleaning & Rodent Proofing Nationwide

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

We provide independent Demilec attic cleaning and rodent proofing in Pflugerville, Texas, with most jobs completed in a single day and pricing put in writing before any work starts. As an independent Demilec service provider, we carry no manufacturer authorization, which means we source parts based on what actually fixes your attic, not what a brand catalog limits us to. Most attic cleaning and rodent proofing jobs in Pflugerville homes with Demilec products run between $1,800 and $4,200 depending on contamination level, accessibility, and whether the spray foam needs sectioned removal. This page is for homeowners in Pflugerville’s Stone Hill Town Center corridor, Windermere, and Blackhawk neighborhoods who found rodent damage, nesting material, or degraded foam in a Demilec-insulated attic and want the problem solved with documentation, not promises.

How Demilec Products Fail - and How We Fix Them

• Demilec SEALECTION 500 open-cell foam develops tacky surface degradation in Pflugerville’s attic heat. Attic temperatures in Pflugerville regularly exceed 140°F from May through September, and SEALECTION 500’s open-cell structure can off-gas plasticizers that leave a sticky residue. Rodents track through it, embedding fur and waste into the foam matrix. We section out the degraded foam with hot-wire tools, HEPA-vacuum the substrate, and apply a non-toxic enzymatic cleaner before reinstalling.
• Demilec Heatlok HFO High Lift creates dense, hard-to-clean cavities when rodents tunnel through it. The high-lift formulation achieves 3.5 inches per pass, which is efficient for coverage but leaves fewer voids for inspection. When mice or roof rats bore channels through Heatlok HFO, the tunnels are narrow and packed with compressed nesting material. We use borescope inspection to map tunnel networks, then remove foam in controlled sections rather than gouging blindly.
• Demilec Heatlok XT two-pound closed-cell foam traps moisture at the roof deck if the original installer skipped vapor-profile analysis. In Pflugerville’s spring storm season, bulk water can migrate through compromised shingles and sit against the foam’s impermeable face. That moisture feeds mold that rodents then track through, spreading spores across the attic. We remove the affected XT sections, dry the deck with targeted airflow, and replace with a vapor-smart assembly that accounts for Pflugerville’s mixed-humidity climate.
• Demilec 500 open-cell around can lights and top plates becomes a rodent highway when air leaks persist. The foam itself is intact, but gaps at the foam-to-drywall interface, common in production builds near Pflugerville’s 130 Corridor, let rodents follow the pressure gradient from conditioned space to attic. We don’t just patch the foam; we seal the actual penetration with fire-rated caulk or intumescent sealant, then test with a smoke pencil to confirm the path is dead.
• Demilec Agribalance, where found in older Pflugerville agricultural conversions, contains bio-based polyols that attract specific pests. The soy-derived content in first-generation Agribalance can retain food-grade oils that draw rodents and insects not seen in petroleum-foam attics. We remove Agribalance entirely in affected zones, sanitize with botanical antimicrobials, and reinstall with a synthetic formulation that eliminates the attractant profile.

Our Demilec Attic Cleaning & Rodent Proofing Process

1. 1
   Written price and scope before entry. We inspect the attic hatch, photograph the access condition, and deliver a flat price with line-item breakdown. No work starts without a signed scope under Haven Standard Clause 1.
2. 2
   Blower-door baseline and attic pressure mapping. We run a blower-door test, a pressurization reading that shows in one number how much conditioned air the house is losing. In Pflugerville homes with Demilec foam, we also measure attic-to-house pressure differential to locate hidden bypasses rodents are using.
3. 3
   Containment and HEPA-negative-air setup. We seal the attic hatch with poly sheeting and run negative air to prevent contamination drift into living space. This matters more with Demilec jobs because degraded foam particles are electrostatic and cling to surfaces.
4. 4
   Sectioned foam removal, substrate cleaning, and rodent exclusion. We remove only compromised Demilec sections, never healthy foam. For Heatlok HFO and SEALECTION 500, we use hot-wire cutting to minimize dust. We then install 26-gauge galvanized steel flashing at all penetration points, concrete patching compound at chimney saddles, and stainless-steel mesh at gable vents.
5. 5
   Sanitization with enzyme treatment and optional re-insulation. We apply a commercial-grade enzymatic cleaner that breaks down rodent urine proteins without degrading remaining Demilec foam. If removal was extensive, we reinstall with Demilec, Reflectix, or another specified product, never over unsealed penetrations.
6. 6
   Post-work blower-door test, photo documentation, and written report. We run the blower-door again and hand you the pre- and post-job CFM50 numbers, plus a photo record of every stage. The report tells you what the house does. The insulation changes what the house does. Those are two different conversations.

What Demilec Attic Cleaning & Rodent Proofing Costs in Pflugerville

These ranges reflect Pflugerville’s current material costs and labor rates. We don’t estimate over the phone for Demilec jobs because foam condition varies too much with age and heat exposure. Every estimate is free, written, and valid for 30 days. Call (737) 259-8352 to schedule.

Why Pflugerville Homeowners Call Topside Attic Insulation Pflugerville for Demilec Work

We’ve been in attics throughout Pflugerville’s Stone Hill Town Center corridor often enough that the regional heat load patterns aren’t a surprise to us. Wes Okafor trained in building systems technology at Kennedy-King College on Chicago’s south side, where instructors drilled air-sealing fundamentals, the idea that blown-in insulation is only half the job if the can lights and top-plates are still leaking. That training shows in how we handle Demilec foam: we don’t treat it as a monolith. SEALECTION 500, Heatlok HFO, Heatlok XT, and Agribalance each fail differently in Central Texas heat, and we document what we find with before-and-after blower-door numbers rather than handshakes.

Our 365-Day Done Right Promise applies to all Demilec attic cleaning and rodent proofing work. If a re-insulated section fails or an exclusion point proves incomplete, we return and make it right. We also service Reflectix and other brands, so if your attic has mixed insulation types or you want to compare performance characteristics, we can source accordingly without proprietary lock-in. Calls are answered by a live person 24/7, and our technicians are background-checked, uniformed, and named in your appointment confirmation text.
