Demilec Attic Cleaning & Rodent Proofing in New Braunfels: What to Know First
We provide independent Demilec attic cleaning and rodent proofing in New Braunfels, typically completing most jobs in one to two days with a written price before any work starts. Demilec spray foam systems, including the Heatlok HFO Pro and Sealection 500 lines common in Comal County homes, require specialized handling during rodent remediation because the foam’s open-cell structure can harbor nesting material and urine salts that standard cleaning won’t address. Most New Braunfels homeowners with Demilec attics call us after finding rodent trails through foam surfaces or noticing compressed insulation where squirrels have tunneled near roof penetrations.

How Demilec Products Fail - and How We Fix Them
- Heatlok HFO Pro surface degradation from rodent gnawing. The HFO Pro’s density profile makes it attractive to roof rats seeking nesting cavities in New Braunfels’ mild winters, particularly in hillside homes off FM 306 where mature oak canopies provide bridge access. We remove compromised sections, treat the substrate with enzymatic cleaner rated for polymeric foam, and install galvanized exclusion barriers before patching with compatible Demilec material or transitioning to a hybrid system where rodent pressure is chronic.
- Sealection 500 moisture retention after rodent urine contamination. Open-cell Sealection 500 can wick urine deep into the matrix; surface sanitizing leaves salts that continue off-gassing ammonia. We use a controlled-depth removal protocol, cutting back to dry substrate rather than treating topically, then replace with closed-cell Heatlok XT in affected cavities where the original spec allows the density upgrade.
- Demilec DemiFoam crumbling at top-plate junctions. The lower-density DemiFoam installed in 2016-2019 New Braunfels builds (common in River Chase and Copper Ridge) becomes friable when rodents compress it for trail paths. We excavate the damaged runs, air-seal the top plates with acoustical sealant first, then reinstall with Heatlok HFO Pro at the higher density spec to restore both R-value and structural integrity.
- Demilec-to-drywall interface separation creating rodent highways. Thermal cycling in unvented New Braunfels attics causes contraction gaps at foam-to-framing boundaries; rodents follow these predictable paths. We map the full envelope with borescope inspection, inject expanding sealant at separation points, and install mechanical exclusion at all penetration clusters.
- Contaminated vapor-retarder facings on Demilec hybrid systems. When Demilec is paired with kraft-faced batts in retrofit jobs, rodent activity in the foam layer often compromises the facing’s integrity without visible damage to the batt below. We strip to the foam substrate, assess facing adhesion with a pull test, and replace only the failed components rather than the full assembly.
Our Demilec Attic Cleaning & Rodent Proofing Process
- 1
Written price before site visit, if photos permit. Text us images of your Demilec attic and rodent evidence; we’ll return a scoped price with line items for removal, sanitizing, exclusion, and restoration materials.
- 2
Blower-door baseline and borescope mapping. We pressurize the house to measure current envelope leakage, then run a borescope through Demilec cavities to locate hidden nesting voids without unnecessary demolition.
- 3
Controlled foam removal and substrate treatment. Cut back contaminated Demilec to sound material, HEPA-extract debris, and apply enzymatic decontamination rated specifically for polyurethane foam systems.
- 4
Air sealing and mechanical exclusion. Seal all top plates, penetrations, and ridge gaps with compatible materials; install galvanized flashing at rodent access points before any restoration begins.
- 5
Demilec restoration or hybrid transition. Reinstall with OEM-specified Demilec product where appropriate, or specify alternative density if the original line is discontinued or the failure pattern suggests a material upgrade.
- 6
Post-job blower-door and photo documentation. We run the pressurization test again, print the pre- and post-job CFM50 readings, and deliver your Documented Photo Record before the crew leaves.
Before
AfterWhat Demilec Attic Cleaning & Rodent Proofing Costs in New Braunfels
Most Demilec attic cleaning and rodent proofing jobs in New Braunfels run between $2,800 and $6,400, with the final price driven by how much foam needs controlled removal, whether the substrate requires enzymatic treatment or full replacement, and the linear footage of exclusion work at roof penetrations. A localized Sealection 500 remediation in a single attic quadrant typically falls at the lower end; whole-envelope Heatlok HFO Pro restoration after extensive roof rat colonization, common in the older oak-canopy neighborhoods between Landa Park and the Guadalupe River, pushes toward the upper range. We also service Reflectix radiant barrier systems when they’re part of the same attic assembly, though Demilec foam work represents the bulk of our remediation calls. Call (830) 243-6352 for a written price before any work starts - estimates are free, and we provide a Free Second Opinion on any competing written quote.
Why New Braunfels Homeowners Call Topside Attic Insulation New Braunfels for Demilec Work
We’ve been independently owned and operated under The Haven Standard since 2016, and we’ve learned that Demilec attics in New Braunfels fail in predictable patterns that generic pest control companies miss. Our technicians are background-checked and uniformed, calls are answered by a live person 24/7, and every job closes with a Documented Photo Record plus printed blower-door numbers when the scope involves envelope restoration. The 365-Day Done Right Promise applies to all completed work. Wes Okafor, who grew up on the South Side of Chicago and trained at Dawson Technical Institute before logging nearly two decades sealing attics across Central Texas, runs every blower-door test personally or trains the technician to his protocol. The number on the blower-door printout tells you what the insulation did. Everything else is just talk.
FAQs
Demilec’s limited material warranty covers original installation defects, not subsequent rodent damage or third-party remediation work. As an independent Demilec service provider, we document our methods with photos and material lot numbers so any future warranty claim on unrelated defects isn’t complicated by our work. Call (830) 243-6352 if you’d like us to review your original installation paperwork alongside our scope.
We source current-production Demilec Heatlok and Sealection lines through authorized distribution for restoration work, though some 2016-2019 formulations are discontinued. When OEM match isn’t available, we specify compatible density and chemistry from our approved supplier list - Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, and GreenFiber - with the substitution noted in writing before work begins.
Replacement is warranted when enzymatic treatment can’t reach urine salts deep in open-cell matrix, when structural compression exceeds 30% of original thickness, or when the blower-door post-remediation reading shows leakage above our sealing target. Most localized contamination in New Braunfels homes permits repair; whole-attic replacement typically follows years of undetected activity or multiple pest-control treatments that drove rodents deeper into the foam.
Most Demilec attic cleaning and rodent proofing jobs in New Braunfels are scheduled within three to five business days of written estimate acceptance, with same-week starts available for active infestation situations where HVAC contamination is suspected. Call (830) 243-6352 - a live person answers 24/7.
You get a written scope completion checklist, before-and-after blower-door readings on applicable jobs, a Documented Photo Record of all work areas, and material specification sheets for any Demilec or alternative products installed. We keep copies filed by address, which has proven useful when New Braunfels homeowners sell and the buyer’s inspector asks questions.
