Icynene Home Energy Audit in Union City: What to Know First
We provide independent Icynene home energy audit in Union City, typically scheduled within 48 hours and completed in a single visit. Most audits run between $280 and $550 depending on home size and test scope, and you’ll get a written price before we start - no exceptions. This page is for Union City homeowners who installed Icynene open-cell or closed-cell foam and need to know whether their building envelope is still performing as designed, or whether gaps, shrinkage, or missed air bypasses are bleeding conditioned air into the attic. Call (650) 381-1512 to book or to get a free second opinion on any written estimate you’ve already received.
How Icynene Products Fail - and How We Fix Them
- Icynene Classic Max (open-cell) shrinkage at stud bays in older Union City framing. The 3.5 lb density foam can pull away from Douglas fir studs common in pre-1980s ranch homes near Alvarado Adobe Park as seasonal moisture cycles expand and contract the wood. We map the gaps with thermal imaging, remove the failed sections, and reapply only after the substrate is conditioned to local equilibrium moisture content.
- Icynene MD-R-200 (closed-cell) thermal drift in Decoto corridor new construction with vented attics. The high R-value per inch degrades when attic ventilation pulls moisture through cut-and-cobble applications, especially where HVAC ducts run through the space. We test with a blower door - a pressurization reading that shows, in one number, how much air your building envelope is losing - then either convert to a conditioned attic assembly or supplement with targeted air sealing at top plates and can lights.
- Icynene H2Foam Lite overspray gaps at complex rooflines in two-story homes near the Union City hills. The lower-density formulation doesn’t always fill birdsmouth cuts and valley framing completely during original installation. Our crew uses boroscope inspection through soffit vents to find voids, then injects compatible closed-cell foam or dense-packs the cavity with cellulose depending on access.
- Icynene Waterblown .5 (legacy open-cell) dusting and surface degradation in crawl spaces with poor vapor management. The water-blown chemistry is more hydrophilic than current HFO-blown formulations; in Union City’s clay-heavy soils where crawl space humidity runs 70% plus in winter, the surface can develop a friable layer that sheds particles into the living space. We encapsulate the crawl with a reinforced vapor barrier and remediate or replace the foam depending on depth of degradation.
- Icynene ProSeal LE (low-emissory closed-cell) delamination from OSB roof sheathing in south-facing Union City attics. The reflective coating can create a thermal barrier that traps summer heat, accelerating adhesive failure when attic peak temperatures exceed 140°F in August and September. We strip the failed material, allow the sheathing to dry to acceptable moisture content verified with pinless meter readings, then reapply with a substrate-specific primer.
Our Icynene Home Energy Audit Process
- 1
Schedule and scope. You call (650) 381-1512, a live person answers, and we book a 2-3 hour window. We confirm whether your Icynene installation was open-cell or closed-cell, the approximate year, and any symptoms you’ve noticed - uneven room temperatures, rising PG&E bills, musty attic smells.
- 2
On-site blower-door test. We install a calibrated fan in an exterior door and depressurize the house to 50 Pascals. The CFM50 reading - cubic feet per minute at that pressure - becomes our baseline. In Union City, a 1,600 sq ft home from the 1960s typically reads 3,500-5,500 CFM50 before any work; post-Icynene installation should be under 2,500 if the air sealing was done right.
- 3
Thermal imaging and physical inspection. We scan every Icynene-treated surface with a FLIR camera, looking for thermal bridging, shrinkage gaps, and missed cavities. In attics, we walk the floor joists and photograph every top plate, penetration, and chimney chase - the photo log becomes part of your documented record.
- 4
Duct leakage testing if applicable. When HVAC ducts run through an Icynene-insulated attic, we pressurize the duct system and measure leakage to outside. Even well-insulated attics lose efficiency when conditioned air leaks into the envelope. We report the CFM25 leakage number and flag any disconnections the foam may have concealed.
- 5
Written findings and priced options. Before we leave, you get a printed summary with your blower-door number, thermal images with annotations, and a flat-price proposal for any remediation. Under Haven Standard Clause 1: no work starts without a written price, written scope, and written warranty.
- 6
Remediation and verification. If you proceed, we complete the air sealing or foam repair, then rerun the blower door. You keep the before-and-after readings, the photo record, and our 365-Day Done Right Promise - if it’s not done right, we make it right.

Why Union City Homeowners Call Topside Attic Insulation Union City for Icynene Work
We’ve sealed and insulated over 9,000 homes since 2016, and the ones that stick with us are the owners who read their three-star reviews as carefully as their fives. They want the blower-door number, not a promise. Wes Okafor, our owner and lead technician, grew up on Chicago’s South Side and learned the trade at Kennedy-King College in Englewood before running crews across the East Bay for well over a decade - from post-war ranches near Alvarado Adobe Park to newer construction along the Decoto corridor. He seals air bypasses before a single bag of blown-in cellulose gets loaded into the machine, and he leaves every customer with a printed blower-door reading, a photo log of the before-and-after attic floor, and a plain-language summary showing exactly how the R-value changed from first walk-through to final inspection.
We’re an independent Icynene service provider - not affiliated with or authorized by Icynene - which means we also work with Reflectix and other brands when that’s the right fix for your assembly. The 365-Day Done Right Promise applies to everything we touch. Calls are answered by a live person 24/7.
FAQs
No. Our audit is non-destructive diagnostic testing - blower door, thermal imaging, visual inspection - and does not alter the foam. We document conditions as-found; if we find installer-error issues like missed stud bays or overspray gaps, we flag them in your report so you can pursue warranty coverage with your original contractor if the installation is still under Icynene’s material warranty. Call (650) 381-1512 if you need help interpreting what we find against your warranty documents.
We source current-spec Icynene products through standard distribution channels for repairs where matching the existing chemistry matters - open-cell to open-cell, closed-cell to closed-cell. For some legacy formulations like Waterblown .5, the OEM chemistry has been superseded, and we use HFO-blown equivalents with better moisture stability. We explain the trade-off in your written scope before any material gets ordered. Want a second opinion on what another contractor proposed? Bring us their estimate - we’ll read it with you.
The blower-door number tells most of the story. If your home depressurizes to under 2,500 CFM50 and the thermal imaging shows only minor shrinkage at a few stud bays, targeted repair and air sealing usually suffices. If you’re over 4,000 CFM50 with widespread delamination or thermal drift through the foam thickness, replacement of the affected assembly is typically more cost-effective than chasing individual failures. We give you both numbers and both options, priced separately. Estimates are free - call (650) 381-1512.
Most audits are scheduled within 48 hours of your call, and the on-site work takes 2-3 hours. Same-week scheduling is usually available if you’re seeing acute symptoms like a sudden PG&E spike or visible foam degradation. A live person answers calls 24/7 - no voicemail loops.
You get four things: your printed blower-door test result with the CFM50 reading, annotated thermal images on a USB drive, a photo log of every inspected surface, and a written findings summary with flat-price repair options if needed. Under the Haven Standard, every job begins with a written price and ends with a documented record - no exceptions. The R-value on the bag is what the material does in a lab. The number on your blower-door report is what your house actually does - and those two figures are not always friends.
Ready to find out what your Icynene envelope is actually doing? Call (650) 381-1512 to book your Union City home energy audit. We’ll answer with a live person, schedule within 48 hours, and deliver a written price before any work starts - plus a free second opinion on any estimate you already have in hand.
