Icynene Spray Foam Insulation in Tustin: What to Know First
We provide independent Icynene spray foam insulation in Tustin with most jobs completed same-day and pricing put in writing before any work starts. Most Icynene spray foam insulation projects in Tustin run between $2,800 and $6,400 depending on whether we’re treating an attic roof deck, garage ceiling, or full rim-joist seal in a raised foundation. This page is for homeowners who already have Icynene foam in their building envelope and need service, expansion, or replacement - or those comparing Icynene against other spray foam options for a Tustin home built or remodeled between 2005 and 2020, when Icynene open-cell formulations were most commonly specified by local architects.

How Icynene Products Fail - and How We Fix Them
- Icynene MD-C-200 shrinkage at roof decks in Tustin’s inland heat. The MD-C-200 open-cell formulation can pull away from rafter bays after five to seven summers of 95°F+ attic temperatures, creating a gap that defeats the air barrier. We find this most often in Tustin Legacy homes with dark shingle roofs. Our fix: remove the compromised lift, re-seal the bay with a compatible open-cell replacement, and verify with a smoke pencil at the ridge.
- Icynene LD-C-50 water absorption in crawl spaces with seasonal moisture. The lower-density LD-C-50 can wick water if the vapor barrier below was incomplete or degraded, leading to odor and R-value loss. We encounter this in the older Tustin Ranch crawl spaces where grading directs water toward the foundation. Our fix: remove affected foam, install a proper 6-mil vapor barrier, then re-apply with closed-cell Icynene or an equivalent Demilec formulation rated for below-grade use.
- Icynene Classic Max inadequate coverage at top plates in balloon-framed additions. When original 1950s Tustin construction meets a 2010s second-story addition, the top plate intersection often gets a thin pass of Classic Max that doesn’t achieve the specified 3.5 inches. Thermal imaging shows the striping. Our fix: expose the plate, build out to full depth with measured lifts, and document with pre- and post-installation thermal images.
- Icynene H2Foam Lite off-ratio curing from improper substrate temperature. Applied to a cold garage ceiling in January without pre-conditioning, H2Foam Lite can cure with a tacky surface or internal voids. We’ve pulled failed lifts from Tustin homes where the installer skipped the substrate temp check. Our fix: remove the uncured material, bring the surface to 60°F minimum, and re-apply with continuous monitoring of the A and B drum temperatures.
- Icynene closed-cell formulations compromised by pest activity. Rodents don’t eat the foam, but they tunnel through it - particularly the older Icynene 5000 series used in some 2008-2014 Tustin builds. Our fix: remove the damaged section, seal entry points with steel mesh and foam, then re-apply. We include rodent-proofing in the scope and document it in the photo record.
Our Icynene Spray Foam Insulation Process
- 1
Call and scope. A live person answers. We schedule a site visit, and you’ll get a text when Wes or a named technician is en route.
- 2
Blower-door test and thermal scan. We pressurize the house to 50 pascals and record the CFM50 baseline. The thermal camera shows where Icynene has failed, settled, or was never properly applied.
- 3
Written price and material selection. We specify whether we’re using OEM Icynene replacement foam or a compatible aftermarket formulation - for example, Demilec Heatlok HFO when closed-cell is needed and Icynene lead times are running long. The price is flat, written, and signed before any work starts.
- 4
Air sealing first, then insulation. Seal the leaks first. Then insulate. The R-value on the bag means nothing if conditioned air is moving through the gap around that recessed can. We seal top plates, can lights, and penetrations before any new foam goes in.
- 5
Installation with continuous documentation. Every lift is photographed. Drum temperatures and pass thicknesses are logged. For applicable jobs, we run the blower door again and publish the before-and-after numbers.
- 6
Cleanup and deliverables. You get the written scope, the photo record, the blower-door results, and the 365-Day Done Right Promise in writing. We leave the site broom-clean.
Before
AfterWhat Icynene Spray Foam Insulation Costs in Tustin
| Job Type | Typical Range | What Moves the Price |
|---|---|---|
| Attic roof deck, open-cell (1,200 sq ft) | $2,800 - $4,200 | Accessibility, existing removal, rafter depth |
| Garage ceiling, closed-cell (400 sq ft) | $3,200 - $4,800 | Height, HVAC duct proximity, fire-rated coating requirement |
| Rim joist seal, closed-cell (full perimeter) | $4,000 - $6,400 | Crawl space clearance, moisture remediation needed first |
| Icynene removal and replacement (per sq ft) | $1.50 - $2.80 | Density of original foam, disposal access, containment needed |
These are real numbers for Tustin homes we’ve worked on - Tustin Legacy, Tustin Ranch, and the older neighborhoods near Old Town. The price goes up when we have to remove failed foam before installing new, or when the 2022 California Energy Code requires additional fire protection at the thermal barrier. It goes down on straightforward new construction where the substrate is clean and accessible.

FAQs
No - Icynene’s warranty covers material defect, not the installation or subsequent service work performed by an independent contractor. As an independent Icynene service provider, we document our work so you have a clear record of what was done and with what materials, which protects both of us if a material claim ever arises. Call (657) 286-7673 if you have a specific warranty concern - we’ll review the paperwork with you.
We source OEM Icynene formulations when the job specifies them and lead times allow - typically 5-10 business days for specialty densities. We also use compatible aftermarket foams from Demilec and other manufacturers we trust, and we tell you which we’re using and why before any work starts. No proprietary lock-in. Call (657) 286-7673 for specifics on your job.
Repair is usually cheaper when less than 30% of the installed area is compromised - typically $800-$1,800 versus $2,800+ for full replacement. We make that call after the blower-door test and thermal scan, and we show you the images so you can see what we see. Call (657) 286-7673 for a free assessment.
Most repairs are same-day. Full attic or garage treatments typically take one to two days, plus a 24-hour cure period before re-occupancy. We schedule around your availability, and you’ll get a text when the crew is on the way. Call (657) 286-7673 to check this week’s availability.
Yes - on every applicable job, we provide before-and-after blower-door readings in CFM50 so you can verify the air-sealing result in one number. This is standard practice for us, not an upsell. The documentation goes in your file with the photo record and written scope. Call (657) 286-7673 to schedule a test.
