Insulation Company in Costa Mesa, CA
Blown in insulation is the most common request we field from Costa Mesa homeowners, and for good reason: it’s the fastest way to fix the comfort gaps in older west-side bungalows and under-insulated east-side two-story homes without tearing out drywall. Your attic is one of the highest-impact areas in your home, and most Costa Mesa houses we inspect simply don’t have enough coverage up there. We match the material to your home, not the other way around. Call (833) 390-3099 for a free estimate.
Why Costa Mesa Homes Are Different
Costa Mesa’s housing splits sharply along the 405, and insulation work here is really two different jobs. The west side, ZIP 92627, is dominated by post-war 1950s-60s single-story stucco tract homes and bungalows. Many of these still have original uninsulated exterior walls and shallow attic cavities that make proper coverage a challenge. The east side, ZIP 92626, has larger 1960s-80s two-story stucco tract homes with more attic depth, but the builder-grade batts we find up there are often thin, settled, or compressed to half their original R-value. Both sides share one thing: this city’s coastal marine layer means cooling load and attic moisture dominate over heating load. The June-gloom damp makes vapor and ventilation detailing just as critical as R-value, especially in the near-beach fog belt west of Newport Blvd. It rarely freezes here, so the real enemy is hot afternoon sun beating on under-insulated attic spaces and the slow, damp creep of marine-layer humidity into whatever’s up there.
Our Main Costa Mesa Services
Most Costa Mesa homeowners call us about two services: attic insulation and spray foam insulation. Both solve real problems in this city’s housing stock, and both deserve their own page to explain how they work here.
Attic Insulation in Costa Mesa
Attic insulation is the single highest-impact upgrade for most Costa Mesa homes, especially in 92627 where the near-beach fog belt means attic jobs frequently turn into moisture remediation. Technicians regularly find damp, compressed, or settled fiberglass from decades of marine-layer humidity in older west-side bungalows. We’ll check your attic’s ventilation before we add material, because adding insulation on top of a moisture problem just locks the problem in. Full details on how attic insulation works in Costa Mesa, including pricing by material, are on our Attic Insulation in Costa Mesa page.
Spray Foam Insulation in Costa Mesa
Spray foam insulation is the right call for Costa Mesa homeowners dealing with hard-to-reach attic knee walls, rim joists, or older east-side two-story homes where HVAC ductwork runs through unconditioned attic space. Closed-cell foam from Icynene and Demilec creates an air seal that fiberglass can’t match, which matters when your attic is also baking in the afternoon sun most of the year. It’s a bigger investment, so we’re straightforward about whether it’s the right fit for your home. See our Spray Foam Insulation in Costa Mesa page for the full breakdown.

Blown In Insulation in Costa Mesa
Blown in insulation is our most-requested service in Costa Mesa because it’s the cleanest way to retrofit an existing attic and fill the shallow, awkward cavities in older west-side 92627 bungalows. In the 92626 two-story homes, we use it to top off thin builder-grade batts and bring the whole attic up to current energy code. The damp marine air this close to the coast means we pay close attention to how the material handles the fog season, and we’ll tell you if cellulose or fiberglass is better for your specific attic before we quote. Read more about how we approach this on our Blown In Insulation hub page.
Cellulose Insulation
Signs you need it
Your attic has settled fiberglass batts from the original build and you can see drywall seams or ceiling joists through the gaps.
What it costs in Costa Mesa
Blown-in insulation in Costa Mesa typically runs $1,500 to $5,000 for a full attic, with cellulose coverage between R-30 and R-38 on the lower end of that range.
How we do it
We air-seal bypasses and can lights, install ventilation baffles at the eaves, then blow cellulose to the specified depth with a machine and a two-person crew.
Blown In Attic Insulation
Signs you need it
Rooms below the attic get noticeably hot by early afternoon in summer while the rest of the house stays manageable.
What it costs in Costa Mesa
Blown in attic insulation in Costa Mesa typically costs $1,500 to $5,000, with the exact figure depending on your attic’s square footage and whether we’re starting from empty or topping off.
How we do it
We measure your attic, check for moisture and ventilation problems first, and then blow material to the depth that achieves your target R-value.
Blown In Cellulose Insulation
Signs you need it
You want an eco-friendly option, and you’re tired of seeing fiberglass dust sift down from ceiling fixtures whenever someone walks in the attic.
What it costs in Costa Mesa
Blown in cellulose in Costa Mesa falls within the $1,500 to $5,000 attic range, with the recycled paper content carrying no meaningful price penalty over fiberglass.
How we do it
We run GreenFiber or similar cellulose through a blower hose and dense-pack it into attic floor cavities, paying extra attention to the shallow corners of west-side 92627 attics.
Blown In Fiberglass Insulation
Signs you need it
Your attic has some insulation from the original build, but it’s thin and settled, and you want a drier option that resists absorbing the marine-layer moisture common west of Newport Blvd.
What it costs in Costa Mesa
Blown in fiberglass in Costa Mesa typically runs $1,500 to $5,000 for an attic job, with the material’s lighter weight making it a good fit where attic depth allows a deeper fill.
How we do it
We blow loose fiberglass to the manufacturer’s coverage chart spec, stopping to check depth with a gauge pole in every section of the attic floor.

What Costa Mesa Customers Say
"Attic was at maybe R-11 from the 1970s and blown in over the top would have just buried the problem. They removed the old material, air sealed the top plates and penetrations first, then blew in to R-49. The upstairs is a completely different house in August."
— Justin Chen"He did a blower door test before and after and gave me the numbers. I like being able to see the difference rather than being told about it."
— Carmen Reyes"Installed baffles at the soffits so the new insulation didn't block the ventilation, which the previous contractor apparently never considered."
— Hector Vargas
