Insulation Company in Lomita, CA
Blown in insulation retrofits are the highest-ROI upgrade for most Lomita homes, especially the 1940s to 1960s one-story stucco tract houses that make up much of the 90717 ZIP. These homes were built when energy was cheap, so many still have open attic cavities with settled loose-fill or thin batt material that has compressed to a fraction of its original R-value. We work with Knauf, Rockwool, and GreenFiber products to bring those attics back to full performance without tearing into walls. Call (844) 241-0737 to schedule a free attic assessment.
Why Lomita Homes Are Different
Lomita’s housing stock creates a specific set of insulation challenges you won’t find in newer South Bay developments. The post-WWII single-story homes along Lomita Boulevard and the Pacific Coast Highway corridor typically have low-pitch or flat roofs with open attic cavities that are easy to access but often lack baffles and proper venting. Many still carry original single-pane windows, but the real thermal leak is overhead. Attics here gain heat all summer and lose it on cool, damp winter nights, which is why attic air-sealing plus blown in insulation outperforms wall retrofits in this climate. We also see a pattern in Lomita’s older attics: old cellulose or loose-fill fiberglass blown up against the eaves decades ago has settled, leaving the center of the attic nearly bare. Techs routinely find R-30 material performing closer to R-11. Because Lomita has one of the South Bay’s oldest median ages, many homeowners want lower bills and steadier indoor temperatures without a full remodel. Blown in insulation delivers exactly that, often in a single day, with no drywall work.
Our Main Lomita Services
Two services account for most of the calls we take from Lomita homeowners. Both are covered in detail on their own pages, but here’s the short version of how each one fits this city’s housing stock.
Attic Insulation in Lomita
Most Lomita attics we inspect have blown-in material that has settled well below its original depth, or fiberglass batts installed decades ago that no longer meet current energy codes. We remove or top up what’s there, air-seal the attic floor, and install fresh material matched to the home’s venting situation. The flat and low-pitch roofs common in the 90717 ZIP make baffle placement and ridge venting especially important, since trapped moisture in a Lomita marine-layer climate causes more damage than heat alone.

Spray Foam Insulation in Lomita
For Lomita homes with attached garages, bonus rooms, or knee-wall attics, spray foam does what blown-in material cannot: it air-seals and insulates in one pass. Open-cell foam works well for interior sound control and attic rooflines, while closed-cell adds structural rigidity and moisture resistance that suits damp South Bay conditions. We install Icynene and Demilec systems, and we’re careful to recommend foam only where it earns its higher cost, never as a default upsell. Spray Foam Insulation in Lomita

Blown In Insulation in Lomita
Blown in insulation is the workhorse retrofit for Lomita’s 1940s to 1960s one-story homes, where open attic cavities make installation fast, clean, and effective. Most of these houses were built with minimal attic insulation, and what was added later has often settled to half its original R-value in the cool, damp conditions the marine layer brings. We typically install Blown In Insulation up to R-38 or R-49 in a single day, air-sealing the attic floor first so the new material actually holds its rated performance.
Loose Fill Insulation
Signs you need it
Rooms that run five to ten degrees warmer than the rest of the house in summer, and a furnace that cycles constantly on cool Lomita nights, usually point to settled or missing loose fill overhead.
What it costs in Lomita
Loose fill insulation in Lomita attics typically runs $1.00 to $2.50 per square foot installed, depending on depth and whether old material needs removal first.
How we do it
We air-seal penetrations and top plates, confirm baffle placement at the eaves, then blow loose fill to a consistent, measured depth across the entire attic floor.
Blown In Cellulose Insulation
Signs you need it
If you can see the tops of your ceiling joists in the attic, or your old insulation looks dusty and compacted rather than fluffy, blown-in cellulose is the straightforward fix.
What it costs in Lomita
Blown in cellulose in Lomita typically lands between $1.25 and $2.75 per square foot installed, with GreenFiber material included in that range.
How we do it
We run a hose into the attic, dense-pack or loose-blow GreenFiber cellulose to the target R-value, and leave the attic cleaner than we found it.
Cellulose Insulation
Signs you need it
Drafts that move through ceiling light fixtures and bathroom vents are a reliable sign your existing cellulose has settled and stopped slowing air movement.
What it costs in Lomita
Cellulose insulation projects in Lomita generally run $1.25 to $2.75 per square foot installed, depending on attic access and existing material condition.
How we do it
We remove or stabilize old material, seal the attic floor, and blow fresh cellulose to an even depth that meets the R-value your Lomita home needs.
Blown In Fiberglass Insulation
Signs you need it
When old fiberglass has been compressed by storage, foot traffic, or decades of settling, it’s lost most of its insulating value and needs topping up or replacement.
What it costs in Lomita
Blown in fiberglass in Lomita typically costs $1.00 to $2.50 per square foot installed, and it’s a good match for shallow attic cavities where cellulose’s weight is a concern.
How we do it
We blow Knauf or CertainTeed fiberglass to the specified depth, checking coverage with depth markers so there are no thin spots over ceilings.
What Blown In Insulation Costs in Lomita
| Item | Typical range in Lomita |

| Air-sealing before blown-in install | $300 – $800 (whole attic) |
| Loose fill / blown in fiberglass | $1.00 – $2.50 per sq ft installed |
| Blown in cellulose | $1.25 – $2.75 per sq ft installed |
What pushes price up in Lomita is usually attic access: flat roofs with tight access hatches, older wiring that needs to be moved before we can air-seal, or attics that were never vented properly and need baffles added. We give an upfront, line-item quote before any work starts, so you won’t get a surprise number at the end.
Is blown in insulation worth it for a Lomita home?
Yes. For a 1,200-square-foot Lomita house with settled attic insulation, a blown-in retrofit usually pays for itself in three to six years through lower heating and cooling bills. The comfort change is noticeable the first week, especially on cool marine-layer nights when rooms used to feel damp and chilly. Call (844) 241-0737 and we’ll assess what your attic actually needs.
How long does blown in insulation take in Lomita?
Most blown in attic jobs in Lomita are done in four to six hours, including air-sealing and setup. We protect the work path with drop cloths, run a hose from the truck to the attic, and leave the home clean before we go. Call (844) 241-0737 to check our schedule for your 90717 home.
