Insulation Company in North Tustin, CA
Blown in insulation solves a problem we see constantly across North Tustin: homes built between the 1960s and 1980s with vaulted ceilings, exposed beams, and attic cavities that were never insulated to modern standards. Add the Santa Ana winds that push hot, dry air through the canyons each fall, and you get rooms that bake in summer and lose heat fast on cool winter nights. Fountain Valley Insulation has served North Tustin since 2014, matching the right material to irregular framing rather than forcing a standard product into custom architecture. Call (833) 390-3099 to talk through what your attic actually needs.
Why North Tustin Homes Are Different
North Tustin is unincorporated Orange County, which means large custom homes on hillsides rather than repeating tract layouts. We work in attics where rafters don’t line up on predictable centers, where add-ons from three different decades meet under one roofline, and where vaulted ceilings leave minimal space for standard batts. That irregularity changes the insulation conversation completely.
The Santa Ana winds are the second factor. They don’t just raise temperatures; they drive fine dust, leaf debris, and embers into attic vents and along canyon edges. Over the years, that material compresses insulation, displaces it against baffles, and reduces its effective R-value. Add rodent activity from the mature landscaping and eucalyptus stands common on these properties, and you find attics where half the insulation has been pushed aside or soiled. Homes in North Tustin also skew toward well water with high mineral content. That’s less about drinking water and more about humidity behavior inside crawl spaces and unconditioned attics. Insulation here has to handle moisture cycles that coastal Orange County homes don’t experience. We carry Rockwool specifically because its mineral wool composition resists moisture absorption and won’t support mold or pest nesting, which matters when you’re insulating a hillside crawl space off a canyon.
Our Main North Tustin Services
Most North Tustin homeowners call us about two things: upgrading attic insulation in an older custom home, or sealing a remodel or addition with spray foam. Here’s what each involves locally.
Attic Insulation in North Tustin
Attic work in North Tustin means dealing with vaulted ceilings, shallow rafter bays, and access hatches tucked into closets or garages. We assess what’s already up there, and in canyon-edge homes that usually means compressed fiberglass or blown material that has shifted under decades of wind-driven debris. From there we recommend either blown-in or batt replacement, depending on your framing and whether you use attic storage. The goal is consistent thermal coverage across every cavity, including the awkward ones add-ons created. Attic Insulation in North Tustin has the full breakdown of what we check and how we price it.
Spray Foam Insulation in North Tustin
Spray foam earns its keep in the unvented attics and crawl spaces we find on hillside properties. Closed-cell foam from Icynene or Demilec seals air movement at the source, which matters when warm air is being pushed through wall cavities by Santa Ana winds. It also adds structural rigidity to add-ons and older roofs. We see North Tustin remodels where spray foam is the only practical way to hit code-required R-values in irregular spaces. Spray Foam Insulation in North Tustin covers the material differences and what a typical hillside application involves.

Blown In Insulation in North Tustin
Blown in insulation is our most-requested service in North Tustin for a simple reason: it conforms to the irregular framing and shallow rafter bays that define custom homes built from the 1960s through the 1980s. Loose-fill fiberglass or cellulose settles into odd cavities, wraps around exposed beams, and fills gaps that rigid batts leave behind. In canyon-edge homes where Santa Ana winds have compressed old attic insulation over the years, blowing in a fresh layer restores thermal performance fast, usually in a single day. You can see the full scope on our Blown In Insulation page.
Cellulose Insulation
Signs you need it
Your attic insulation sits below the top of the joists, or you can see bare ceiling drywall in spots.

How we do it
We run a hose to the attic, blow the material to a consistent depth, and level it across every bay.
Blown In Fiberglass Insulation
Signs you need it
Rooms below the attic swing hot in summer and cold in winter, or your current attic insulation looks thin and uneven.
What it costs in North Tustin
Blown fiberglass costs $0.90 to $2.40 per square foot installed in North Tustin homes.
How we do it

Is blown in insulation worth the cost in North Tustin?
Yes. North Tustin attics routinely lose meaningful R-value from Santa Ana wind compression and debris. A fresh blown-in layer restores coverage for less than most other insulation methods. Call (833) 390-3099 for a precise number.
Can you blow insulation into an attic with vaulted ceilings?
Usually, yes. We work around vaulted cavities by blowing material into the accessible rafter bays and using baffles to keep airflow channels open. Call (833) 390-3099 and we’ll tell you what your specific roofline allows.
Brands We Service in North Tustin
We carry Rockwool for mineral wool applications, CertainTeed for fiberglass and cellulose lines, and Icynene plus Demilec for spray foam work. That means we stock the right material for North Tustin’s mix of vaulted attics, hillside crawl spaces, and remodels instead of pushing one product. See our brands for specifics on what fits your project.

What North Tustin Customers Say
"Plastic laid from the front door to the attic hatch and they vacuumed the hallway afterward."
— David Tran"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."
