Blown In Fiberglass Insulation in Tustin
Blown In Fiberglass Insulation is loose fiberglass blown through a hose into the attic cavity or into wall voids, and in Tustin it’s the most common retrofit we install in attics that currently have thin or settled material. The fiberglass comes from Knauf or CertainTeed, depending on the R-value target and the attic’s existing condition. In a typical Tustin Ranch home from the 1970s, you’re looking at $1,400 to $2,800 to bring an attic from R-19 up to R-38 or R-44. The job takes four to seven hours, including setup and cleanup.
What makes fiberglass the right call in Tustin is its resistance to settling. In attics that hit 140°F, cheaper blown products can compress over time. The fiberglass we install holds its depth, which is the whole point of the R-value. It’s also non-combustible by nature, which matters when you’re insulating around recessed can lights and older wiring that’s common in Tustin’s 1960s and 1970s tract homes.
Attic blanket upgrades over existing insulation
We can blow fiberglass directly over settled loose-fill, provided the old material is dry and not harboring rodent activity. In Tustin homes where the original cellulose from the 1980s has compressed to half its labeled depth, a 10- to 14-inch fiberglass blanket on top restores the R-value without a full removal. The old material stays in place, and the new fiberglass fills the gaps the old fill left behind.
Dense-packing wall cavities
For Tustin bungalows with empty or partially filled wall cavities, we dense-pack fiberglass at low pressure through 2-inch holes drilled into the wall sheathing or through the interior plaster. This is the method we use on homes near Old Town where the original lath and plaster is too fragile for spray foam. The fiberglass fills every void without expanding pressure against the plaster keys, and the access holes are patched to match.
Loose Fill Insulation in Tustin
Loose Fill Insulation is the broad term for any insulation blown into a cavity in loose form, and in Tustin the smartest loose-fill choices are cellulose for wall retrofits and fiberglass for open attics. Loose fill is the fastest path to a sealed building envelope in Tustin’s older housing stock because it gets into irregular cavities that batts can’t: the sloped ceilings in 1920s bungalows, the narrow stud bays in 1940s cottages, the awkward knee walls in dormered attics. Expect $2,200 to $4,500 for a full attic and wall retrofit on a 1,200-square-foot pre-war Tustin home.
Cellulose loose fill, in particular, is what we recommend for Tustin’s historic homes because it can be dense-packed into wall voids at low pressure. That matters when you’re working with original plaster and lath. Too much pressure and the plaster keys snap off the lath and the wall cracks. Too little and you get voids. Our crews run the pressure settings specific to the wall assembly, not a generic factory number.
Cellulose for historic wall cavities
GreenFiber cellulose is a recycled-paper product treated with borates for fire and pest resistance. It’s our default for dense-packing Tustin’s pre-1950s wall cavities because it flows into irregular spaces better than fiberglass and settles into a tight, air-sealing mass. In a 1930s bungalow near Old Town, this is often the only way to insulate walls without tearing out the original plaster.
Radiant barrier and ventilation pairing
In Tustin, loose fill alone won’t fix a 140°F attic. We pair blown insulation with ventilation checks and, where needed, a radiant barrier on the underside of the roof deck. A properly vented Tustin attic with R-38 or better loose fill and a radiant barrier can drop attic temperatures by 20 to 30 degrees in July. That’s the difference between an upstairs bedroom that holds 72°F and one that won’t drop below 80°F at 6 p.m.
Trusted Brands We Service in Tustin
Aspen Attic Insulation Orange County stocks materials from eight industry brands, and for Tustin work we lean on Rockwool for fire-resistant applications, Knauf for fiberglass blow-in, and Icynene for spray foam where the job calls for it. We choose the product based on your house, not on what’s left in the warehouse. When a Tustin homeowner calls about blown in insulation, we arrive with the right material on the truck, sized for the R-value you’re paying for and the cavity we’re filling. That’s what the 365-Day Done Right Promise is for: if it’s not installed correctly, we return and fix it at no charge, in writing, covering labor and materials for a full year.
Common Blown In Insulation Problems We See in Tustin Homes
- Settled loose-fill in 1970s attics. The original cellulose or fiberglass in Tustin Ranch homes has often compressed from R-30 down to R-15 or less. The fix is a fresh blown blanket on top, not a full removal.
- Empty wall cavities in pre-war bungalows. Many 1920s and 1930s homes near Old Town were built with no wall insulation at all. Dense-packing through small access holes is the only retrofit that doesn’t destroy the original plaster.
- Cracked plaster from improper drilling. If a contractor uses a standard masonry bit on lath and plaster, the plaster cracks and the repair shows. Our crews use plaster-specific bits and low-speed drilling to keep the finish intact.
- Overheated attics overwhelming good insulation. Even R-38 blown fiberglass can’t overcome a 140°F attic with no ventilation. In Tustin, we check soffit vents, ridge vents, and duct sealing on every blown-in job because the attic heat in August will undo the insulation’s work otherwise.
Pricing for Blown In Insulation in Tustin, CA
Here’s what Tustin homeowners can expect to pay. Attic-only blown fiberglass to R-38 runs $1,400 to $2,800 for a typical 1,200 to 1,800 square foot home.

A full attic-plus-walls project on a pre-1950 bungalow near Old Town lands between $3,200 and $6,300. Attic access through a closet in Tustin Meadows, existing insulation removal, and rodent remediation all move the number. Every price is put in writing before work starts.

FAQs About Blown In Insulation in Tustin
Yes. Dense-packed cellulose or fiberglass is blown through small access holes drilled through the plaster or through the exterior sheathing, filling the original wall cavities without removing the lath and plaster. Our crew did exactly this on a 1930s bungalow on Main Street near Old Town: using a 2-inch hose and low-pressure setting to avoid blowing out the old plaster keys, we dense-packed every exterior wall and added a 14-inch blanket in the attic, cutting the homeowner’s July cooling runtime by nearly a third. The access holes were patched and the walls read clean. Call (559) 249-4794 if you want a written price for your bungalow.
Blown fiberglass holds up well as long as the attic is vented and the initial depth is correct. The problem in Tustin isn’t the insulation degrading from heat; it’s that settled or thin insulation lets 140°F attic air bleed into the living space through the ceiling, and if ducts run through the attic, they’re conducting that hot air into every room. We install to R-38 or R-44 and check ventilation on every job. That’s the part generic pages leave out.
Fiberglass holds its loft longer in open attics and is the better blanket material for Tustin Ranch’s 1970s and 1980s tract homes. Cellulose is better for dense-packing walls and irregular cavities because it flows tighter and air-seals better. For a Tustin Ranch attic, we’d blow fiberglass to R-38 or higher. For the walls, if they’re open or accessible, we’d dense-pack cellulose. Both cost roughly the same per square foot installed, within 10 to 15 percent.
Not always. If the old insulation is dry, uncontaminated, and not compressed to the point of blocking airflow, we can blow new material directly on top. If the old material is water-damaged, full of rodent droppings, or so settled it’s trapping heat, removal is the right call. In Tustin’s 1960s and 1970s homes, the old cellulose is often just settled, not ruined. We’ll tell you after looking at it, and the written quote will reflect either path.
Most Tustin Meadows single-story attics take four to six hours, start to finish. That includes setup, blowing the insulation to depth, ventilation checks, and full cleanup. Wall dense-packing adds another two to three hours depending on how many exterior walls we’re filling. We schedule one-day jobs so you’re not waiting around. Call (559) 249-4794 and we’ll give you a time window and a written price.
