Icynene Wall Insulation in New Braunfels: What to Know First
We provide independent Icynene wall insulation service in New Braunfels, with most injection foam and drill-and-fill jobs completed in a single day and pricing put in writing before any work starts. Our crews work with Icynene’s open-cell and closed-cell formulations regularly, and we carry compatible materials from Owens Corning, Johns Manville, Knauf, and Reflectix when a hybrid approach makes more sense for the wall assembly.
This page is for homeowners in New Braunfels who already have Icynene insulation in their walls and need to add it, replace it, or fix what another installer left behind. If you’re seeing drafts through outlets, hearing every conversation from the next room, or watching your energy bills climb despite what was supposed to be a sealed envelope, we can help. Call (830) 243-6352 and we’ll schedule a walk-through with a written price.
How Icynene Products Fail - and How We Fix Them
- Icynene Classic Max shrinkage in stud cavities. Classic Max, the open-cell formulation common in 2010s New Braunfels builds, can pull away from framing members as it ages, especially in walls that cycle through our hot, humid summers and occasional hard freezes. We find the gaps with thermal imaging, then inject compatible closed-cell foam or perform a drill-and-fill with Rockwool where the cavity geometry demands it.
- Icynene MD-R-200 moisture retention in exterior walls. This medium-density closed-cell product performs well until the wall’s drainage plane fails - something we see in homes near the Guadalupe River corridor where wind-driven rain hits hard. When MD-R-200 saturates, it loses R-value and can harbor mold. We remove the compromised section, repair the water entry point, and reinstall with a vapor-profile analysis so it doesn’t happen again.
- Incomplete cavity fill from original installation. Icynene’s pour-fill application for existing walls requires precise pressure and temperature; too many crews in the New Braunfels area rushed the cure time in summer heat, leaving voids above headers and behind fire blocks. We use borescope inspection to map the gaps, then drill and inject at controlled pressure until the cavity is full.
- Thermal bridging at Icynene-insulated walls with metal studs. Icynene doesn’t fix conductivity through the framing itself. In the metal-stud townhomes near Creekside, we’ve measured wall assemblies where the insulation read R-19 but the effective R-value was closer to R-9 because of thermal bridging. We add a continuous exterior insulation layer or recommend strategic interior furring with additional foam, depending on the cladding and budget.
- Acoustic underperformance in Icynene-filled interior walls. Homeowners who chose Icynene for soundproofing between bedrooms or media rooms are sometimes disappointed. Open-cell Icynene absorbs some sound, but it doesn’t block low-frequency transmission the way dense-packed cellulose or Rockwool does. We can retrofit with a second fill of GreenFiber or install resilient channel and a second layer of drywall where the wall is open.
Our Icynene Wall Insulation Process

- 1
Call and scheduling. A live person answers at (830) 243-6352, 24/7. We book a site visit, and you get a text when your technician is en route - Haven Standard: Arrive on schedule, named technician, no surprises.
- 2
Diagnostic walk-through and blower-door test. We pressurize the house and measure CFM50 - cubic feet per minute of air leakage at 50 Pascals of pressure - to establish a baseline. Then we thermal-scan the walls, check outlets and switch plates for airflow, and borescope any suspicious cavities.
- 3
Written scope and price. Before anyone lifts a tool, you get a flat price, a written scope of work, and a written warranty. This is Haven Standard Clause 1. No exceptions, no “we’ll figure it out as we go.”
- 4
Air sealing first, then insulation. We seal top plates, electrical penetrations, and any gaps at the rim joist before adding or replacing Icynene. Blowing insulation over unsealed leaks is something we don’t do.
- 5
Installation with materials matched to the job. We use Icynene-compatible products or source directly from our supplier network - Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, GreenFiber, and Reflectix - depending on what the wall assembly needs. No proprietary lock-in.
- 6
Post-job blower-door test and documentation. We run the house again and print the before-and-after numbers. You get the photo record, the test report, and a copy filed by your address. The number on the blower-door printout tells you what the insulation did. Everything else is just talk.
Before
AfterWhat Icynene Wall Insulation Costs in New Braunfels
Most Icynene wall insulation jobs in New Braunfels run between $2,800 and $6,500 for a typical single-family home, depending on wall area, cavity condition, and access. Here’s how the pricing breaks:
- Drill-and-fill injection foam (existing walls, 2×4 construction): $3.50-$5.50 per square foot of wall area
- Open-wall spray foam (remodel or new construction): $2.80-$4.20 per square foot
- Removal and replacement of failed Icynene: $4.50-$7.00 per square foot (includes disposal, cavity prep, and reinstall)
- Interior soundproofing upgrade with hybrid fill: $5.00-$8.50 per square foot
What moves the price: accessibility (stucco or brick exterior costs more to drill than siding), cavity obstructions like fire blocks or old wiring, and whether we need to bring in a third-party abatement crew for mold or rodent damage we discover. We price for what we find, not what we hope to find. Call (830) 243-6352 for a written estimate - there’s no charge for the visit, and we offer a free second opinion on any competing written quote you bring us.
Why New Braunfels Homeowners Call Topside Attic Insulation New Braunfels for Icynene Work

We’ve sealed and insulated over 9,000 homes since 2016, and a growing share of our wall work in New Braunfels involves fixing or completing Icynene installations that didn’t perform as promised. Wes Okafor, our owner, started this trade at Dawson Technical Institute on the South Side of Chicago and has spent nearly two decades chasing air leaks through Central Texas attics and walls. He and his crew know the local conditions - the stack-effect pressure in slab homes off River Road, the way our clay soils shift wall assemblies, the humidity that finds every gap.
We’re an independent Icynene service provider, not a factory-authorized dealer, which means we can recommend Reflectix radiant barriers, Rockwool batts, or dense-packed cellulose when those materials solve your problem better than another round of foam. Every job carries our 365-Day Done Right Promise, backed by the written scope and warranty you receive before work starts. And when you call (830) 243-6352, a live person answers - no voicemail loop, no callback window measured in business days.
FAQs
No - Icynene’s limited material warranty covers product defects regardless of who installs it, provided the product was applied to manufacturer specifications. What voids coverage is improper application (wrong thickness, temperature, or moisture conditions during install), not the lack of a dealer relationship. We document our installation conditions with photos and written records so any future claim has support. Call (830) 243-6352 if you want us to review your existing warranty language with you.
Most jobs finish in one day; larger homes or those requiring exterior siding removal may need two. Drill-and-fill work through interior drywall is slower but less disruptive to landscaping. We’ll tell you which approach your house needs and how long it takes in the written scope, before anyone schedules the crew. For timing on your specific job, call (830) 243-6352.
Repair makes sense when the failure is localized - a few shrunken cavities, a single wet section, incomplete fill above a header. Full removal is the better call when the product has degraded across the wall, when we find multiple moisture events, or when the original install used a formulation incompatible with your current HVAC and moisture loads. We borescope first and show you what we found, so the decision is based on what your walls actually contain. Free estimates; call (830) 243-6352.
We can match the thermal performance and air-sealing characteristics, though exact batch color and cell structure vary between production runs and aging. For repairs in visible areas, we discuss whether a seamless aesthetic matters or whether the repair will be behind baseboard or cabinetry. We source from the same supplier network - Icynene, Demilec, and compatible third-party formulations - so the repair performs as a system even if the label differs. Call (830) 243-6352 to discuss your specific repair.
The honest answer: you can’t tell by looking. A wall can feel solid and still leak air or lose R-value to moisture. We verify performance with a blower-door test - the pressurization diagnostic Wes Okafor runs before and after every job - plus thermal imaging to spot gaps the eye misses. If another contractor installed your Icynene and never gave you a number, we can test it and show you what’s actually happening. Call (830) 243-6352 to schedule; estimates are free.
