Insulation Company in North Tustin, CA
Blown in insulation solves a specific problem in North Tustin: homes built between the 1960s and 1990s with original loose fill that has settled to a fraction of its intended depth. Those large custom ranch and Mediterranean-style houses on half-acre lots lose conditioned air through sloped ceilings, vaulted spaces, and gaps around recessed lights. In summer, when afternoon temperatures climb past 95°F, under-insulated attics push cooling bills higher than they should be. Maple Insulation Co fixes that with blown in cellulose and fiberglass matched to the existing cavity and the county’s Title 24 energy compliance rules. Call us at (855) 341-6045 for a free estimate.
Why North Tustin Homes Are Different
North Tustin is unincorporated Orange County, which means no city-level building department and no municipal rebate programs for insulation upgrades. Homeowners fall under county code and California’s Title 24 energy standards. That regulatory patchwork changes how we scope a job. We document existing R-values, check for settled or compressed material, and write quotes that account for county inspection requirements when applicable. It also means there’s no local incentive to offset cost, so material selection matters more. We often recommend blown in cellulose where existing fiberglass has settled because it can be dense-packed over old material without a full tear-out.
The housing stock creates its own set of challenges. Large ranch homes with complex rooflines, vaulted ceilings, and multiple skylights make attic access tight and coverage irregular. We see original 1970s blown in insulation in the sloped sections above living areas that has compacted to half its original depth. Flip renovations add another layer of trouble: gaps around recessed lights, attic hatches that don’t seal, and bypasses hidden behind newer drywall. In this climate, those gaps leak conditioned air year-round. The inland heat bakes attics for months, and Santa Ana winds dry out and degrade exterior insulation seals, so interior attic work has to be done right the first time.
Our Main North Tustin Services
North Tustin homeowners call us most often about two things: attic insulation that needs an upgrade after decades of settling, and spray foam for hard-to-reach areas or homes being renovated to tighter energy standards. Each handles a different set of problems, and we don’t push one over the other.
Attic Insulation in North Tustin
Most attic work in North Tustin involves working around vaulted ceilings, skylights, and recessed light housings in homes built decades ago. We inspect what’s up there, measure settled depths, and recommend whether to top off existing material or remove and replace. In homes with original 1970s blown in product, we commonly find R-value ratings far below what Title 24 expects today. The fix usually pays for itself through lower summer cooling costs.

Spray Foam Insulation in North Tustin
Spray foam earns its keep in North Tustin’s custom homes because it seals gaps that batts and loose fill can’t reach. Complex rooflines, tray ceilings, and chase ways around skylights all leak air. Open-cell foam works well in attic roof decks where you want air sealing plus thermal resistance. Closed-cell adds moisture control, which matters when Santa Ana winds push dust and dry air into exterior cavities. We install both Icynene and Demilec lines and choose based on the structure, not the inventory. See Spray Foam Insulation in North Tustin for details.

Blown In Insulation in North Tustin
Blown in insulation in North Tustin typically runs $1.50 to $3.50 per square foot installed, depending on material, depth, and whether we’re topping off existing product or starting fresh. Most jobs take a single day. The bigger issue in this area is the condition of what’s already up there: homes built in the 1970s and 1980s often have original loose fill that has settled to half its installed depth, especially in sloped ceiling sections above living areas. We check coverage with a depth gauge rather than guessing, because visual inspections miss compaction. For a deeper look at how we handle these installations, see our Blown In Insulation service page.
Cellulose Insulation
Signs you need it
Your attic has old fiberglass that’s compressed, dusty, or uneven across the floor, and your upstairs rooms fluctuate more than the rest of the house.
What it costs in North Tustin
Blown in cellulose in North Tustin averages $1.50 to $2.80 per square foot installed, with GreenFiber recycled cellulose on our material list for homeowners who want recycled-content coverage.
How we do it
We air-seal the attic floor penetrations first, then dense-pack or loose-blow cellulose to the R-value the county requires, making sure coverage is uniform around recessed lights and hatch openings.
Blown In Attic Insulation
Signs you need it
Your cooling bill keeps climbing every summer while the upstairs feels ten degrees warmer than the thermostat setting, and the attic floor shows bare spots or settled rows between joists.
What it costs in North Tustin
Blown in attic insulation in North Tustin generally runs $1.50 to $3.50 per square foot, with the final number driven by access difficulty, depth target, and how much old material we need to remove first.
How we do it
We map the attic, seal air leaks at top plates and can lights, mark target depth, and blow fiberglass or cellulose evenly across every bay, including the tricky sloped sections common in North Tustin ranch homes.
Loose Fill Insulation
Signs you need it
Your attic has shallow, uneven coverage after decades of settling, and you can see joist tops in places that should be buried under material.
What it costs in North Tustin
Loose fill runs from $1.50 to $3.00 per square foot in North Tustin, with cellulose on the lower end and premium fiberglass blends higher.
How we do it
We remove or level the old material where needed, seal bypasses, and blow new loose fill to a consistent depth measured across the entire attic floor.

Can you add blown in insulation over what’s already up there?
Yes, in most North Tustin homes we can blow new cellulose or fiberglass directly over settled existing material after checking for moisture and sealing air leaks. It saves the cost of a full removal.
How long does blown in insulation last in this climate?
Cellulose typically holds its R-value for 20 to 30 years in North Tustin’s dry inland climate, though settling and Santa Ana dust infiltration reduce effectiveness over time. Call (855) 341-6045 to have us check your current depth.
