Icynene Blown In Insulation in San Diego: What to Know First
Icynene blown in insulation in San Diego homes usually means one of two things: either you have Icynene open-cell spray foam that’s settled, shrunk, or been damaged, and you need blown-in material to fill the gaps – or you’re combining Icynene’s spray-applied air barrier with loose-fill insulation on top. Either way, we handle it as an independent Icynene service provider, not a manufacturer rep. Most jobs are finished within one to two days, and you get a written price before anyone opens a can or starts a blower. Call (858) 282-0169 if you’re seeing drafts, hot rooms, or an electric bill that’s climbing for no reason you can find.
This page is for San Diego homeowners who already have Icynene in their attic or walls and need honest answers about what failed, what it costs to fix, and who’s showing up to do it.
How Icynene Products Fail – and How We Fix Them
Icynene’s spray foam lines have been in San Diego attics for over two decades. We see the same failure patterns repeat across neighborhoods from Chula Vista to Escondido. Here’s what actually goes wrong:
- Icynene Classic (open-cell, light-density) shrinkage and settling. The older Classic formulation can pull away from rafters and top plates after years of San Diego’s heat-soak cycles. That leaves hairline gaps along framing where attic air leaks through. We fill those cavities with blown-in fiberglass or cellulose to restore the air seal and the R-value in one pass.
- Icynene ProSeal and ProSeal LE thin spots. These closed-cell products sometimes get sprayed too thin in hard-to-reach corners – usually where the roofline meets the exterior wall. A thin pass doesn’t give you the air barrier you paid for. We identify the thin areas with a thermal check, then dense-pack blown-in material into the void to close the gap.
- Rodent and pest damage in Icynene foam. Rats and mice in San Diego attics chew through open-cell foam like it’s soft cheese. Once they’ve tunneled through the Icynene, the insulation value drops and the air leaks come back. We remove the damaged sections, seal entry points, and re-insulate with blown-in material that pests don’t nest in as readily.
- Moisture-compromised open-cell Icynene. Open-cell foam absorbs water. A roof leak or a bathroom fan venting into the attic can saturate the foam and turn it into a damp sponge that holds moisture against your framing. We pull the wet foam, dry the cavity, and blown-in insulation goes back in once the space is dry and the leak is fixed. You don’t want damp insulation against San Diego roof decking in August.
- Icynene MD-R-200 and MD-C-200 homeowner patch jobs gone wrong. These are the two-component kits you can buy at building supply stores. Homeowners sometimes try a small patch themselves, and the foam doesn’t cure right – too cold, wrong mix, or they skimped on prep. The result is a crusty, off-ratio mess that doesn’t insulate and off-gasses. We cut it out and redo the area properly. No judgment; we’ve just seen too many of these to count.
Our Icynene Blown In Insulation Process
Every Icynene job in San Diego follows the same playbook. Here’s what happens from the first call to the final walkthrough:
- 1
You call, a person answers. Not a recording, not a call center. A live person at (858) 282-0169 gets your address, what you’re seeing, and schedules a visit.
- 2
You get the tech’s name and photo before the visit. Our dispatcher sends it to your phone. The person who shows up at your door is the same person in the photo, wearing a clean marked uniform and a photo ID badge.
- 3
We do a real walkthrough. Garrett Sloane or one of our senior techs goes into the attic, checks the Icynene condition, finds the air leaks, and measures. We tell you what’s actually wrong before we quote a dollar figure.
- 4
You get a written price before work starts. No verbal estimate, no “we’ll see how it goes.” The number on the page is the number you pay. That’s the Threshold Standard, and it applies to every job we do in San Diego.
- 5
We do the blown-in work and clean up. Hoses go in through the attic access, material goes down to the specified depth, and we leave your attic cleaner than we found it. We show up, we do the job right, and we leave your attic better than we found it.
- 6
You get the 365-Day Done Right Promise in writing. If anything fails within a year, we come back and fix it free. Labor and materials, covered.
What Icynene Blown In Insulation Costs in San Diego
Honest numbers, because you shouldn’t have to guess:
- Filling gaps and voids in existing Icynene: $400 to $900 for most San Diego attics. This covers dense-packing blown-in fiberglass or cellulose into shrinkage gaps, thin spots, or rodent-damaged sections.
- Partial removal of damaged Icynene plus blown-in replacement: $1,200 to $3,000 depending on how much foam has to come out, how accessible the attic is, and whether we’re dealing with moisture or pest damage.
- Full attic re-insulation over existing Icynene: $2,500 to $6,000 for a typical 1,200 to 2,000 square foot San Diego home. Price moves with attic size, access difficulty, and the depth of blown-in material you need to hit code.
- Attic air sealing before blown-in work: $600 to $1,500. This is the step that makes the insulation actually work. If your Icynene has shrunk or pulled away, the air leaks are doing more damage than the missing R-value.
What moves the price: attic access, how much damaged foam needs removal, whether pest control or moisture remediation is involved first, and the target R-value for your zone. You’ll get a written quote before any work starts. Call (858) 282-0169 for a free estimate.
Why San Diego Homeowners Call Aspen Attic Insulation San Diego for Icynene Work
Aspen Attic Insulation San Diego has been doing attic and insulation work since 2002, and we’re part of the Threshold Group family. We carry eight material brands – Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber – so when your Icynene needs a blown-in companion, we’re not forcing one product into every situation. Sometimes the right answer is blown-in fiberglass over the foam; sometimes it’s cellulose. Sometimes you need a reflective barrier like Reflectix on a west-facing San Diego attic wall to knock down radiant heat. We stock what works, not what’s convenient. And every tech who walks through your door is background-checked, identity-verified, and sent to you by name and photo before the visit. If anyone else shows up, the visit is free and we make it right.
FAQs
Icynene’s warranty covers the foam material itself, not the installation work done by independent contractors. Adding blown-in insulation over or alongside existing Icynene does not void the manufacturer’s material warranty, but we always recommend checking your original paperwork first. As an independent Icynene service provider, we work in a warranty-safe way – we don’t disturb intact foam, and we document everything before and after. Call (858) 282-0169 and we’ll walk through your specific situation.
Most Icynene blown-in jobs in San Diego are scheduled within a few days of your call, and the actual work usually takes one to two days. We answer the phone 24/7, so if you’ve got a roof leak pouring into your Icynene foam at 9 p.m., a live person picks up and gets you on the schedule. For real emergencies – wet foam, exposed wiring, pest damage that’s letting critters into the house – we’ll move things around to get there faster.
For small shrinkage gaps, thin spots, or a single rodent-damaged section, repair is almost always cheaper – typically $400 to $900 in San Diego. If the Icynene is more than 15 to 20 years old, has widespread moisture damage, or was never installed to the right depth in the first place, you’re often better off blowing in a full layer of new insulation rather than chasing patches. The math depends on your attic’s square footage and the condition of what’s up there. We’ll tell you straight which one makes sense, and the estimate is free either way.
Blown-in insulation doesn’t need to match the Icynene visually – it goes in the same attic cavity, not as a decorative finish. What matters is the R-value and the air-sealing performance. We’ll spec the blown-in material that complements your existing foam, whether that’s fiberglass for dry San Diego attics or cellulose where you want better air-blocking and rodent resistance.
Properly installed blown-in fiberglass or cellulose over Icynene will hold its R-value for 20 to 30 years in San Diego’s climate, assuming no roof leaks or pest problems. The foam underneath isn’t going anywhere if it was installed right. And if anything we install fails within the first year, the 365-Day Done Right Promise covers the repair – labor and materials – with a free second visit. That’s in writing on every job.
