Icynene Crawl Space Encapsulation & Vapor Barrier in Inglewood: What to Know First
Icynene spray foam in a crawl space usually fails because of installation shortcuts, not the product itself, and in Inglewood the failure shows up as moisture wicking through open-cell foam, sagging closed-cell lifts, or foam pulling away from rim joists. As an independent Icynene service provider, we diagnose and fix these problems, then encapsulate the crawl space so it stays dry. Most Icynene crawl space encapsulation jobs in Inglewood run between $2,800 and $6,500 depending on square footage and how much of the existing foam needs correction, and we complete the majority in a single visit.
This page is for Inglewood homeowners who already have Icynene in their crawl space and are seeing dampness, odors, or rising humidity. If that’s you, call (424) 622-5846 and a live person answers, 24/7. No voicemail, no answering service.
How Icynene Products Fail, and How We Fix Them
Icynene made open-cell spray foam popular in Southern California, and we see two of their lines most often in Inglewood crawl spaces: Icynene Classic (a lighter-density open-cell foam) and Icynene ProSeal (a closed-cell formula). Both are good products. Both fail in predictable ways when a crawl space wasn’t prepped right.
- Icynene Classic wicking moisture at the sill plate. Classic is open-cell, which means it absorbs and holds water like a sponge if the crawl space has standing water or persistent ground moisture. In Inglewood’s marine layer climate, we regularly see rim joist foam that feels damp to the touch six months after install. We cut out the saturated sections, fix the moisture source, and reapply with closed-cell or a vapor-impermeable barrier system.
- ProSeal pulling away from concrete. Closed-cell foam needs a clean, dry substrate to bond. When a previous installer sprayed over dusty foundation walls or during a humid stretch, the foam lifts and leaves a gap where air and moisture pass right through. We’ve opened up more than a few Inglewood crawl spaces near Morningside Park where the foam peeled off in sheets. The fix is mechanical removal and proper reapplication with surface prep.
- Incomplete coverage at the band joist. The band joist is the most important air-sealing point in a crawl space, and it’s also the most commonly skipped or under-sprayed area. An inch of foam here does almost nothing. We see this on Icynene jobs where the installer ran short on material. We build it back to the correct depth for the cavity.
- Unsealed crawl space vents defeating the foam. Classic Icynene is air-permeable. If the original install left vent screens in place and open, outside humidity pours in and the foam can’t do its job. Encapsulation means closing and sealing those vents, then letting the foam handle the conditioned space above it.
- Rodent damage to exposed foam. Rats and mice chew through open-cell foam easily, and Inglewood neighborhoods near older housing stock deal with this constantly. Torn foam leaves thermal holes. We remove the damaged material, recommend rodent proofing, and reseal so the crawl space is tight again.
Our Icynne Crawl Space Encapsulation & Vapor Barrier Process
Here’s how a typical Icynene correction and encapsulation job goes when you work with our crew:
- 1
Call and diagnosis. You reach a live person at (424) 622-5846, day or night. We schedule a crawl space inspection, and Neil Ashford or one of our senior techs walks you through what we find.
- 2
Crawl space assessment. We measure humidity, check the existing Icynene for saturation, delamination, and coverage gaps, and identify where water is entering. This is the diagnostic step that tells us whether the foam can stay or needs correction.
- 3
Moisture control first. No encapsulation works over standing water. We address drainage, sump pump needs, or groundwater intrusion before any foam or vapor barrier goes in.
- 4
Icynene correction. We remove failed foam, repair partial coverage, and seal the band joist and rim joist correctly. For reapplication, we choose the right foam type for Inglewood’s humidity, not whatever is cheapest.
- 5
Vapor barrier and sealing. We install a heavy-duty vapor barrier over the ground and up the foundation walls, seal seams and piers, and close crawl space vents permanently.
- 6
Test and guarantee. We verify humidity levels are dropping and foam is bonded before we leave. Every job carries our 90-Day Done Right Promise: if it’s not right, we make it right.
What Icynene Crawl Space Encapsulation & Vapor Barrier Costs in Inglewood
Here’s what we typically quote for Icynene crawl space work in Inglewood:
- Vapor barrier only (600-1,000 sq ft crawl space): $1,800-$3,200
- Full encapsulation with vapor barrier, vent sealing, and rim joist foam correction: $3,500-$6,500
- Icynene removal and reapplication of failed sections (per 100 sq ft of wall area): $400-$800
- Crawl space cleanout and debris removal before encapsulation: $300-$900 depending on access and volume
What moves the price: crawl space square footage, how much existing foam needs correction, whether drainage or a sump pump is required, and how accessible the space is. We give upfront pricing, no surprises. Call (424) 622-5846 for a free estimate, and remember: the seasonal tune-up is $89 if you want us to inspect an existing Icynene install before problems start.

Why Inglewood Homeowners Call Warmline Insulation Co. for Icynene Work
We’ve served Inglewood since 2011, and we’ve worked in homes from the blocks around SoFi Stadium to the neighborhoods off Century Boulevard. Our technicians are background-checked and uniformed, and they know Icynene’s open-cell and closed-cell lines the way a mechanic knows an engine. If your crawl space has a different foam brand, like Reflectix radiant barrier products, our techs handle those too, but Icynene is what we see most often in this part of the city.
Neil Ashford built this company on the principle that the work should speak for itself, and so should your energy bill. Ten service categories under one contractor means you don’t juggle multiple trades when a crawl space job turns into an air sealing or attic insulation project. One visit covers most jobs. One team handles the whole envelope.
FAQs
No, correcting improper installation doesn’t affect your Icynene warranty, but we document everything we remove and reapply, including photos and humidity readings, so you have a record if a warranty claim ever comes up. We’ve done this for Icynene homeowners across Inglewood.
We can match Icynene Classic or ProSeal in most cases, and we’ll tell you honestly whether a different foam type will perform better in your specific Inglewood crawl space. Sometimes a closed-cell foam is the smarter choice even if the original was open-cell.
We schedule most Icynene crawl space assessments within 48 to 72 hours, and emergency moisture situations can often be seen same day. Call (424) 622-5846 and a live person will tell you the next available slot.
Repairing failed sections is almost always cheaper than full replacement, unless the foam is saturated with moisture throughout or rodent damage is extensive. We’ll show you what we find and give you a repair quote before we recommend any full replacement. Estimates are free.
