We provide independent Demilec attic cleaning and rodent proofing in Leander, TX, with most jobs completed in one day and written pricing delivered before any work starts. As an independent Demilec service provider, we are not affiliated with or authorized by Demilec, but our technicians have worked on enough Demilec open-cell and closed-cell installations in Leander to know where the brand’s products hold up and where they need attention after rodent damage or contamination. Typical turnaround from call to completion is 24-48 hours for standard cleanouts, with same-day response for active infestations.

This page is for Leander homeowners who have Demilec spray foam in their attic and are dealing with rodent activity, soiled insulation, or the aftermath of a pest problem that has compromised the thermal envelope.

How Demilec Products Fail - and How We Fix Them

• Demilec Heatlok HFO Pro yellowing and surface degradation after rodent urine exposure. The HFO blowing agent in this closed-cell series produces a slightly more porous surface skin than earlier HFC-blown formulations, which means rodent urine penetrates the top 1/8-inch rather than beading. We do not spot-clean and hope; we cut back to sound foam, treat the substrate with an enzyme neutralizer, and reinstall matching density so the R-value patch reads true on thermal imaging.
• Demilec Sealection 500 open-cell sagging in Leander’s 140°F July attics. Open-cell foam relies on adhesion to the substrate, and when rodents compress or disturb the surface, the reduced contact area plus thermal cycling causes delamination at the rafter interface. We remove the compromised section, recondition the wood surface, and reinstall at the specified lift thickness so the vapor permeance stays within the 10-15 perms Sealection 500 was designed for.
• Demilec Heatlok XT rigid board edge gaps from rodent tunneling at perimeter bands. Rodents prefer the path of least resistance, and the cut edges of board stock at eaves and band joists provide it. We do not caulk over the damage; we remove the tunneled sections, inspect for air leakage at the rim joist, and reinstall with proper perimeter seal so the blower-door number does not climb after we leave.
• Demilec Agribalance organic-oil-based foam odor recurrence after incomplete sanitization. The castor-oil derivative in this bio-based series retains organic compounds that standard bleach treatments do not fully neutralize. We use a two-stage process: HEPA vacuum to remove particulate, then a botanical enzyme treatment formulated for polyurethane substrates, verified with a handheld VOC meter before we close the job.
• Demilec closed-cell shrinkage at stud bays creating rodent highways. Shrinkage of 2-3% is within Demilec’s spec, but in Leander’s new construction boom, fast-track installation during high humidity can push that to 5-7% at the edges. Rodents find these gaps and enlarge them. We fill with matching two-component foam, shave flush, and verify with a smoke pencil so the air barrier stays continuous.

Our Demilec Attic Cleaning & Rodent Proofing Process

1. 1
   Call and scheduling. A live person answers 24/7. We ask about the Demilec product line if you know it, the age of the installation, and whether the damage is active or historical. We schedule a site visit with a written price to follow.
2. 2
   On-site assessment and documentation. Our technician inspects the attic with a FLIR camera and calibrated ruler card, photographs all compromised Demilec foam, and records pre-work conditions. You get a copy of every photo.
3. 3
   Written scope and price. Before any work starts, you receive a written scope specifying: square footage of foam removal, sanitization method, replacement material (OEM Demilec or specified equivalent), and the 365-Day Done Right Promise. No work begins without your signature.
4. 4
   Execution: seal, clean, restore. We seal active entry points first. Then HEPA vacuum all contaminated material, apply substrate-appropriate sanitization, and reinstall foam to the original R-value and depth. Seal the envelope first. Then fill it.
5. 5
   Verification and closeout. On jobs with accessible blower-door reference, we note the improvement. All customers receive a Documented Photo Record showing before, during, and after conditions. Wes Okafor reviews every file before it goes out.

What Demilec Attic Cleaning & Rodent Proofing Costs in Leander

Most Demilec attic cleaning and rodent proofing jobs in Leander fall between $1,800 and $4,200, with smaller spot repairs on limited contamination starting around $950. Full attic restoration after extensive rodent damage to a Demilec Heatlok system typically runs $3,400-$5,800 depending on square footage and whether the HVAC plenum was compromised.

What moves the price: the linear footage of foam removal, whether the substrate needs reconditioning or full replacement, access difficulty (steep pitches in Crystal Falls add time), and whether we are matching discontinued Demilec formulations with current equivalents. We do not quote by phone without photos; we do provide a written price on site that is valid for 30 days. Call (737) 252-7159 to schedule a free estimate.

Why Leander Homeowners Call Topside Attic Insulation Leander for Demilec Work

We have worked on Demilec installations in Leander since the 2016 building boom, including jobs in Crystal Falls, Mason Hills, and Travisso where attic temperatures routinely hit 140°F in July and undersized R-values show up on every FLIR scan. Our technicians know the difference between Heatlok HFO Pro and Heatlok XT, and they know which Leander suppliers stock Demilec-compatible two-component foam for same-day patch work. If your job also involves Reflectix radiant barrier or another brand’s product, we service those too - no proprietary lock-in, no referral to another contractor. The 365-Day Done Right Promise applies to all completed work, and every job closes with a Documented Photo Record, not a handshake and a receipt.
