Icynene Attic Cleaning & Rodent Proofing in New Braunfels: What to Know First
We provide independent Icynene attic cleaning and rodent proofing in New Braunfels, with most jobs completed same-day or next-day once we run our initial inspection. Typical turnaround from call to finished work runs 24-48 hours, and we give you a written price before anyone touches your attic - no exceptions. This page is for homeowners who already have Icynene spray foam or open-cell insulation in their attic and need cleanup, decontamination, or rodent exclusion that won’t compromise what was already installed. Call (830) 243-6352 to schedule. We’ll read your attic’s condition, explain what we found, and hand you a flat price before we start.
How Icynene Products Fail - and How We Fix Them
- Icynene Classic Max (open-cell) - moisture loading and compression loss. The Classic Max line, common in 2016-2020 New Braunfels builds, absorbs atmospheric moisture when the attic’s humidity control fails, usually because bathroom exhaust ducts terminate inside the attic rather than through the roof. The foam doesn’t rot, but it compresses and loses R-value. We remove the degraded sections, trace the moisture source to its penetration, seal it properly, then reinstall compatible open-cell or recommend a hybrid closed-cell repair depending on the roof deck configuration.
- Icynene MD-R-200 (medium-density closed-cell) - rodent tunneling at perimeter joists. MD-R-200 cures hard enough that rodents can’t chew through it, but they’ll burrow along the edges where foam meets wood framing, creating galleries that compromise both insulation value and air sealing. We find these tunnels with borescope inspection, remove contaminated foam, treat the substrate with enzyme cleaner, and reinstall with full perimeter bonding so there’s no gap to exploit.
- Icynene LD-C-50 (low-density open-cell) - dust and allergen trapping in surface texture. The open-cell surface of LD-C-50, popular in Garden Ridge and River Road-area homes for its sound-dampening properties, acts like a filter when attic air circulates through unsealed soffits. Over years it loads with rodent dander, pollen, and construction dust. We HEPA-vacuum the surface, apply a non-ionic surfactant wash that won’t break down the foam chemistry, and finish with a vapor-smart seal coat where the original spec calls for it.
- Icynene Water Blown Series - delamination from OSB roof decks in summer heat. New Braunfels attic temperatures peak above 140°F in July and August. The water-blown chemistry in early Icynene formulations can release residual moisture under sustained heat, causing the foam to pull away from oriented strand board decking. We cut back to sound adhesion, treat for mold if the gap trapped condensation, and reinstall with a high-temp-compatible closed-cell product that handles our local thermal cycling.
- Retrofit overspray jobs - incompatible materials layered over Icynene. We regularly find attics in older New Braunfels neighborhoods like Gruene and Comal Town where a previous contractor blew fiberglass or cellulose directly onto Icynene without understanding surface bonding requirements. The loose fill slides off the foam, creates voids, and provides nesting material for rodents. We strip the incompatible layer, clean the Icynene substrate, and reinstall only materials certified for contact with the specific Icynene line in place.
Our Icynene Attic Cleaning & Rodent Proofing Process

- 1
Attic inspection with photo documentation. We photograph every Icynene surface, identify the product line by cell structure and density, and mark contamination zones, compression areas, and rodent entry paths.
- 2
Written scope and flat price. Before work starts, you get a written scope naming the Icynene line we found, the specific repairs needed, and a single number. Haven Standard Clause 1: no work without a written price.
- 3
Containment and HEPA extraction. We isolate the attic from living space, then vacuum loose debris and contaminated material with HEPA filtration. Rodent waste gets bagged for proper disposal per Comal County guidelines.
- 4
Substrate repair and reinstallation. Damaged Icynene comes out; sound foam stays. We match replacement material to the original chemistry where possible, or specify a compatible alternative if the line is discontinued. OEM Icynene when available, quality aftermarket with matching spec when it’s not.
- 5
Rodent exclusion and air-sealing verification. Every penetration, soffit gap, and roofline intersection gets sealed with rodent-proof material. We run a blower-door test - a pressurization reading that shows, in one number, how much conditioned air your envelope leaks - before and after, so you leave with printed proof of what changed.
- 6
Documented Photo Record and 365-Day Done Right Promise. You get before/after photos, blower-door readings if applicable, and a written warranty. If it’s not right, we make it right.
Before
AfterWhat Icynene Attic Cleaning & Rodent Proofing Costs in New Braunfels
Most Icynene attic cleaning and rodent proofing jobs in New Braunfels run between $1,800 and $4,200, with simpler cleanouts and spot repairs at the lower end and full restoration with extensive foam replacement at the upper. What moves the price: the square footage of contaminated Icynene, whether we can match the original product line or need to substitute, rodent damage to ductwork or wiring that requires trade coordination, and accessibility - tight attics in historic Gruene cottages take longer than open trusses in newer Canyon Lake-area builds.
We also service Reflectix radiant barrier systems when they’re part of the same attic assembly, and we’ll note any interaction between your Icynene and other insulation brands during inspection. Call (830) 243-6352 for a free estimate - we read your attic, explain what we found, and hand you a written price before any work starts.
Why New Braunfels Homeowners Call Topside Attic Insulation New Braunfels for Icynene Work

We’ve worked Icynene attics across New Braunfels since 2016, from the slab homes off River Road where stack-effect leakage runs higher than owners expect, to the newer builds in Vintage Oaks with hybrid foam-and-fiberglass systems. Wes Okafor and our crew know the difference between Classic Max and MD-R-200 by sight and density, and we don’t guess at compatibility. The 365-Day Done Right Promise covers every job, and our live-answered phone means you’re not waiting through callback windows when rodents are active in your attic. The number on the blower-door printout tells you what the insulation did. Everything else is just talk.
FAQs
No, professional cleaning and repair by a qualified contractor does not automatically void Icynene’s warranty, but using incompatible materials or untrained labor can. We work as an independent Icynene service provider, document every product we install, and can provide material spec sheets if your warranty claim requires them. Call (830) 243-6352 if you need help navigating a warranty question.
We use OEM Icynene when the line is still in production and available through regional distribution. For discontinued formulations, we source quality aftermarket with matching density, R-value, and vapor permeance, and we document the substitution in your written scope. You see exactly what goes in before it goes in.
Replacement is necessary when more than roughly 30% of the foam surface shows compression, delamination, or contamination that can’t be surface-cleaned, or when the original product line has known chemistry issues we can’t safely patch. We make that call during inspection and show you the photos so you understand why. Most jobs we see in New Braunfels are repairable.
We schedule inspection within 24 hours for active rodent situations, and we can often start work same-day once you approve the written price. We don’t leave you waiting with open soffits or chewed foam exposed.
Patching is almost always cheaper than full removal and replacement with a different system, unless the Icynene was improperly installed from the start. A full switch runs $6,000-$12,000 in most New Braunfels attics versus our typical repair range. We only recommend removal when the foam itself is the problem, not just the condition it’s in. Call (830) 243-6352 for an exact quote - estimates are free.
