Icynene Wall Insulation in Converse: What to Know First
We provide independent Icynene wall insulation service in Converse, with most jobs scheduled within 48 hours and completed in a single day. A typical drill-and-fill wall job on a 1,800-square-foot ranch runs between $2,800 and $4,200, and we put that price in writing before anyone touches a tool. This page is for homeowners who already have Icynene in their walls and need to know whether to repair, supplement, or replace it, and what that actually costs in the Converse market. Call (830) 420-0953 to schedule a free estimate with a written scope.
How Icynene Products Fail - and How We Fix Them
- Icynene Classic Max shrinks in Converse heat cycles. The open-cell formula can pull back from studs after repeated summer expansion and contraction, leaving thermal bypass channels. We find this most often in south-facing walls in neighborhoods like Live Oak and Windcrest-adjacent areas where afternoon attic temperatures exceed 140°F. Our fix: remove the compromised sections, seal the cavity with closed-cell Icynene MD-R-200 at the exterior sheathing plane, then reinstall open-cell to the interior. The closed-cell layer locks the assembly dimensionally.
- Icynene LD-C-50 settles in tall wall cavities. This lower-density open-cell product was specified heavily in 2018-2021 builds with 9-foot and 10-foot first-floor walls common in newer Converse subdivisions. Gravity wins over time; we measure 2-4 inch gaps at the top of cavities. We drill at stud bay midpoints, inject additional LD-C-50 with adhesive binder, and verify fill with borescope inspection. No guesswork on whether the cavity is full.
- Icynene MD-R-200 develops face-seal failures at window bucks. The medium-density closed-cell product is excellent until the rigid foam shears against inadequately flashed window rough openings, a detail we see in 2017-2019 builds near Converse’s FM 1518 corridor. Water vapor drives inward, delaminating the foam from the stud. We cut back to sound substrate, install a fluid-applied weather barrier at the buck, and respray MD-R-200 to the original thickness. The window gets reflashed while we’re in the wall.
- Icynene H2Foam Lite absorbs moisture in rim joist applications misapplied as wall foam. Some Converse contractors used this product below-grade and extended it into above-grade wall cavities. In our clay-heavy soils, seasonal moisture wicks upward and the hydrophilic open-cell retains it. We remove H2Foam Lite from the affected wall base, treat any framing, and transition to MD-R-200 for the above-grade portion with a capillary break at the sill plate. The assembly dries and stays dry.
- Icynene Classic Max loses adhesion to OSB sheathing with high moisture content at install. This is a historical install issue, not a product defect: crews spraying in Converse’s humid shoulder seasons (March-April, October-November) without conditioning the cavity first. The foam bonds to surface moisture, then releases as the OSB dries. We remove the delaminated foam, dry the cavity with targeted airflow, and respray. Our written scope specifies ambient and substrate moisture readings before any gun triggers.
Our Icynene Wall Insulation Process
- 1
Call and scheduling. A live person answers, or you text us. We book a 2-hour arrival window, not “morning” or “afternoon.”
- 2
On-site assessment and blower-door test. We pressurize the house to 50 pascals and record the CFM50 reading - the single number that shows how much conditioned air your envelope is losing. For Icynene wall jobs, we also run infrared to locate voids and thermal bridging without opening every wall.
- 3
Written price and scope. Before anyone lifts a tool, you get a flat price, a written scope specifying Icynene product line and application thickness, and a written warranty. Haven Standard Clause 1: no work starts without it.
- 4
Air sealing first, then insulation. We seal top plates, electrical penetrations, and duct boots before adding or replacing any Icynene. Seal the leaks first. Then insulate. The numbers will tell you if it worked.
- 5
Installation and documentation. Our crew installs to the written spec, photographs each critical stage, and runs a post-job blower-door test. You get the before-and-after CFM50 readings, the photo record, and a final walkthrough.
- 6
Cleanup and 365-Day Done Right Promise. We leave with the work documented and the promise in force: if it’s not done right, we make it right.
Before
AfterWhat Icynene Wall Insulation Costs in Converse
These are real ranges for jobs we’ve written prices on in the Converse market, not teaser rates:
| Job Type | Typical Range | What Moves the Price |
|---|---|---|
| Drill-and-fill open-cell supplement (1,800 sq ft home) | $2,800 - $4,200 | Wall height, cavity condition, access (interior vs. exterior drill) |
| Closed-cell MD-R-200 exterior wall replacement (partial) | $4,500 - $7,800 | Square footage, sheathing repair needs, flash-and-batt transition details |
| Rim joist correction (H2Foam Lite removal + replacement) | $1,800 - $3,400 | Linear feet, framing condition, vapor barrier integration |
| Interior wall soundproofing with Icynene Classic Max | $3,200 - $5,600 | Number of walls, electrical box sealing, STC rating target |
Price drivers specific to Converse: homes near the Randolph Air Force Base flight path often need enhanced sound attenuation, which changes product selection and cavity fill density. Older ranch homes near Foster Road may have balloon framing or irregular stud spacing that slows installation. We price for what we find, not what we hope to find.

Why Converse Homeowners Call Topside Attic Insulation Converse for Icynene Work
We’re an independent Icynene service provider - not affiliated with or authorized by Icynene - which means we source the product that solves your problem, not the product we’re obligated to move. Our crew includes techs who’ve sprayed Icynene, Demilec, and Reflectix systems, so when a Converse wall assembly needs a hybrid approach, we don’t force a single-brand solution. Wes Okafor runs the blower-door test himself on jobs where the envelope change matters, and we publish those numbers: 4,200 CFM50 before, 2,100 after, on a recent Live Oak ranch with failed Classic Max. The 365-Day Done Right Promise applies to every job, backed by the written scope you received before we started. Calls are answered by a live person, 24/7. No voicemail loops.
FAQs
Icynene’s product warranty covers manufacturing defects regardless of who installs it, but application warranties are issued by the original installing contractor and typically don’t transfer. We provide our own written warranty on workmanship and materials for every job we complete. Call (830) 420-0953 and we’ll review what’s in force on your specific installation.
We match the Icynene product line - Classic Max, LD-C-50, MD-R-200 - and where aesthetic finish matters on interior walls, we can plane and trim the new foam to blend with the existing surface. For exterior walls, the repair is behind drywall or siding and invisible. We document the product spec in your written scope so there’s no mismatch in thermal performance.
Spot repair is usually 40-60% less than full removal and replacement, but only makes sense when the failure is localized and the remaining foam is well-adhered and dry. We borescope and moisture-test before recommending either path. On jobs where more than 30% of the cavity volume is compromised, full replacement becomes the better long-term value. We’ll show you the photos and the numbers, then price both options in writing.
We prioritize water-damaged wall assemblies and typically schedule within 24 hours for active intrusion that threatens framing. The first visit is assessment and drying plan - we don’t spray into wet cavities. Once the substrate is below 19% moisture content, we proceed with the scope we priced. Call (830) 420-0953 and specify the moisture issue; we’ll triage accordingly.
We stock Icynene Classic Max, LD-C-50, and MD-R-200 in our San Antonio-area warehouse, so standard jobs don’t wait on material. Specialty formulations or large commercial quantities may need 3-5 business days. We confirm material availability when we write the price, not after we’ve started.
