Icynene Wall Insulation in Leander: What to Know First
We provide independent Icynene wall insulation service in Leander, with most injection foam and drill-and-fill jobs scheduled within three to five business days and completed in a single day. Our written price lands before any work starts - no exceptions - and every job closes with a documented photo record and, where applicable, before-and-after blower-door numbers. If you own a Leander home built between 2005 and 2018 with Icynene in the walls, you’re likely seeing settling, shrinkage, or the gaps that open when foam pulls away from studs during our dry Hill Country winters. Call (737) 252-7159 for a free estimate and a written scope you can compare.
How Icynene Products Fail - and How We Fix Them
- Icynene Classic Max shrinks in exterior walls. The open-cell formulation pulls away from framing members when relative humidity drops below 30% for extended periods, which happens every January and February in Leander. We find 3/8-inch to 1/2-inch gaps at stud edges during thermal imaging. Our fix: remove the compromised foam, seal the cavity with closed-cell Icynene MD-C-200 at the exterior sheathing plane for a vapor retarder, then backfill with fresh open-cell to the original R-value.
- Icynene H2Foam Lite degrades when roof leaks go undetected. The hydrophilic surfactant in early batches absorbs moisture rather than shedding it, and in Leander’s sudden summer downpours, any flashing failure saturates the foam. It turns yellow-brown and loses structural adhesion. We cut out the affected sections, dry the cavity with desiccant tubes for 48 hours, then reinstall with closed-cell to prevent recurrence.
- Icynene LD-C-50 settles in balloon-framed walls. Common in Crystal Falls and Travisso builds from 2010-2014, where two-story exterior cavities weren’t fully filled at installation. Gravity completes the job over five to seven years, leaving a 12-inch to 18-inch void at the top plate. We drill at the header, verify with a borescope, then dense-pack the void with GreenFiber cellulose or inject new Icynene depending on the customer’s preference and the wall assembly.
- Icynene MD-R-200 develops thermal drift in metal-stud walls. The higher density closed-cell can delaminate from galvanized studs when the building experiences repeated thermal cycling, which is every Leander summer day above 100°F followed by 70°F nights. We remove mechanically, grind the studs clean, apply a compatible primer, and reinstall with Demilec Heatlok Soya as an alternative when the customer wants to avoid the same failure mode.
- Icynene Classic Plus creates odor issues in interior soundproofing applications. The amine catalyst off-gasses when the foam is disturbed during remodeling, particularly in media rooms and home offices near 183A. We extract the disturbed material, ventilate the cavity for 72 hours, and reinstall with Knauf EcoSeal for customers sensitive to residual VOCs.
Our Icynene Wall Insulation Process

- 1
Call and scope. A live person answers 24/7. We schedule a site visit, not a phone estimate. Wes Okafor or a senior tech arrives with a FLIR camera, borescope, and blower-door rig.
- 2
Diagnostics and documentation. We pressurize the house, run thermal imaging, and photograph every wall cavity of concern. You get the images same-day via email. No guesswork.
- 3
Written price before any work starts. Under Haven Standard Clause 1, the scope, materials list, flat price, and warranty terms arrive in writing before anyone lifts a tool.
- 4
Air sealing first, then insulation. Seal the envelope first. Then fill it. We seal top plates, electrical penetrations, and plumbing chases before adding or replacing any foam. The blower-door test runs again mid-job to verify.
- 5
Installation with verified depth. For injection jobs, we drill at 16-inch centers, inject to refusal, and verify fill with a borescope. For open-cavity work, we use a calibrated ruler card every 24 inches. Photos every step.
- 6
Final test and documentation. Post-install blower-door reading, documented photo record, and written report with pre- and post-CFM50 numbers. The 365-Day Done Right Promise activates at signature.
Before
AfterWhat Icynene Wall Insulation Costs in Leander
| Scenario | Typical Range | What Moves the Price |
|---|---|---|
| Injection foam, single-story 2,000 sq ft home, 4 exterior walls | $3,800 - $5,400 | Cavity depth, stud spacing, access (siding type for drill points) |
| Drill-and-fill remediation, settled LD-C-50, 12-cavity section | $1,200 - $1,900 | Height of void, interior vs exterior access, finish repair |
| Closed-cell replacement, H2Foam Lite water damage, 6-cavity area | $2,100 - $3,400 | Drying time required, sheathing condition, primer needs |
| Interior soundproofing, Classic Plus removal and replacement, single room | $1,600 - $2,800 | Room size, existing drywall handling, alternative foam specified |
Most Leander jobs fall in the middle of these ranges. Factors that push higher: three-story construction in Crystal Falls, hardie board siding that requires pilot holes and dust collection, or cavities containing knob-and-tube wiring that must be abandoned first. We also carry Reflectix and other brands for customers who want to compare alternatives. Call (737) 252-7159 - estimates are free, and we provide a Free Second Opinion on any written estimate you’ve already received.
Why Leander Homeowners Call Topside Attic Insulation Leander for Icynene Work

We’ve sealed and insulated over 9,000 homes since 2016, and the Leander jobs stick in memory: the 2019 Crystal Falls house where the attic hit 142°F and the wall cavities were still losing conditioned air at 3,800 CFM50; the Travisso remodel where three contractors had quoted insulation without running a blower door. We don’t start until the air leaks are sealed, we don’t finish until the numbers prove it worked, and we don’t ask for trust without documentation. Every customer gets a written price, a written warranty, and a photo record. If something’s not right in the first year, we make it right. That’s the 365-Day Done Right Promise, Haven Standard.
FAQs
Icynene’s product warranty covers manufacturing defects regardless of who installs, but installation warranties from the original applicator are separate. As an independent Icynene service provider, we document every cavity with photos and depth measurements so any future product claim has evidence. Our own 365-Day Done Right Promise covers workmanship. Call (737) 252-7159 if you need help interpreting your original warranty paperwork.
We source Icynene Classic Max, MD-C-200, and LD-C-50 directly through authorized distribution. For customers open to alternatives, we also install Demilec Heatlok Soya and Knauf EcoSeal when the building science supports it. We never use cut-rate generic foam in a wall cavity - the density and adhesion specs matter too much. Your written scope names the exact product before work starts.
Spot remediation costs 40% to 60% less than full-cavity removal, but only works when the remaining foam is dry, well-adhered, and thermally continuous. We verify with borescope and moisture meter. If the foam is compromised throughout the cavity, partial repair becomes false economy. We’ll show you both scopes and price both paths. Call (737) 252-7159 for an exact quote - estimates are free.
Most Icynene wall insulation jobs in Leander schedule within three to five business days, with emergency water-damage remediation available faster. Single-day completion is standard for injection foam up to 2,500 square feet of wall area. We answer calls 24/7, and you’ll get a text when your technician is en route. Call (737) 252-7159 to check this week’s availability.
Yes, and often we improve it. Original Icynene installations in Leander homes from 2005-2012 were frequently spec’d at R-13 in 2×4 walls and R-19 in 2×6 walls, which meets code minimum but underperforms in our climate. We calculate actual R-value based on your framing depth and target, then verify installed depth with a calibrated ruler card. The written report states the achieved R-value, not the intended one.
