Insulation Company in North Tustin, CA
Blown in insulation is the most common retrofit call we get in North Tustin, and that’s no accident. The custom ranch and split-level homes built here between the 1950s and 1970s went up when energy was cheap and building codes asked very little of a home’s thermal envelope. Many of those attics still carry the original R-11 fiberglass batts, now settled, compressed, and doing almost nothing against the inland summer heat that climbs into the 90s. If your energy bills spike every August and your second floor never cools down, the problem is almost always under-insulated attic space. Call (855) 795-2118 and we’ll tell you exactly what’s up there and what it should cost to fix.
Why North Tustin Homes Are Different
North Tustin sits far enough inland to catch real summer heat, but its housing stock was designed for a milder climate that no longer matches reality. These are large custom ranches and split-levels on big lots, many with vaulted or beamed ceilings that leave almost no attic cavity to insulate at all. When the original single-pane windows are still in place, heat pours in through the glass while whatever insulation exists in the attic struggles to block the radiant heat baking down through the roof deck. Winter works the reverse: cool nights near freezing pull heat out through the same under-insulated ceiling planes that failed in summer.
The neighborhoods off Newport Avenue and throughout Cowan Heights add another wrinkle. Many of those hillside homes have exposed, uninsulated rafters, and decades of remodels, rerouted HVAC ducts, and whole-house fan installations have disturbed whatever cellulose or fiberglass was originally blown or batted in place. We routinely find attics in North Tustin where the insulation looks adequate from the access hatch but has settled to R-8 or worse across half the footprint. Air sealing matters as much as adding material here. A blower-door test shows homeowners why: the stack effect pulls conditioned air straight out of the attic through can lights, plumbing penetrations, and framing gaps, no matter how much new insulation goes in on top.
Our Main North Tustin Services
Two services account for most of the work we do in North Tustin: attic insulation retrofits for those big 1950s to 1970s ranch homes, and spray foam for the vaulted ceiling and exposed rafter situations where batts simply don’t fit.
Attic Insulation in North Tustin
Most North Tustin attics we open up still have the original R-11 or less, and after 50 to 70 years of settling, compression from storage, and disturbance from HVAC work, the effective R-value is often half that. Our Attic Insulation in North Tustin work starts with an honest look at what’s actually up there: depth, condition, air leaks, and whether the existing material is doing anything worth keeping. We then air seal the ceiling plane and bring the attic up to current code levels, choosing between blown-in fiberglass and cellulose depending on the home and the homeowner’s priorities. The houses here have enough attic square footage that this single upgrade usually delivers the fastest, most noticeable change in comfort and cooling cost.
Spray Foam Insulation in North Tustin
Vaulted ceilings, beamed ceilings, and exposed rafter bays are common throughout North Tustin’s custom homes, and they all share the same problem: no conventional attic cavity to insulate. Spray Foam Insulation in North Tustin addresses those spaces directly against the roofline. We install both Icynene and Demilec systems, which matters because open-cell and closed-cell foams solve different things. Open-cell is often the right call for sound control and cost-effective thermal coverage in a standard vaulted ceiling. Closed-cell adds structural rigidity and vapor control, which we recommend more in hillside homes prone to moisture movement. The material choice depends on what the specific roof assembly needs, not what’s on the shelf.

Blown In Insulation in North Tustin
Blown in insulation is the workhorse retrofit material for North Tustin’s housing stock. The typical 1960s ranch or split-level here has a sprawling attic floor with open framing cavities that make loose-fill installation fast, effective, and far less disruptive than tearing out drywall. Adding blown in material on top of settled, underperforming batts and loose fill is usually the single most direct fix for rooms that bake in summer and chill in winter. Because we stock GreenFiber cellulose, Johns Manville fiberglass, and Knauf blown products, the material conversation starts with your attic and your priorities, not with whatever brand happens to be on the truck. See our full Blown In Insulation service details for the methods and materials we use across every job.
Cellulose Insulation
Signs you need it
Your attic insulation has settled below the top of the ceiling joists, your upstairs runs five to eight degrees warmer than downstairs in summer, and you’d prefer a recycled-content product with strong air-blocking performance.
What it costs in North Tustin
Blown in cellulose for a typical North Tustin attic runs $1,800 to $4,500 depending on square footage and whether we’re topping off existing material or starting from near zero.
How we do it
We air seal the ceiling plane first, then blow GreenFiber cellulose to a consistent depth matched to your target R-value, with careful baffling at every eave vent to keep airflow moving.
Blown In Attic Insulation
Signs you need it
Your attic has bare spots, uneven coverage, or old fiberglass batts that have compressed and settled to R-11 or less, and you want full, consistent coverage across the entire attic floor.
What it costs in North Tustin
Blown in attic insulation across an entire North Tustin ranch home commonly lands between $2,200 and $5,000, with larger split-levels and two-story homes running higher.
How we do it
We remove any material that’s too far gone, air seal all penetrations and top plates, then blow loose fill to a uniform, measured depth across every square foot of the attic floor.
Loose Fill Insulation
Signs you need it
Your attic has open framing bays, irregular joist spacing, or areas that batts can’t cover cleanly, and you need insulation that fills every corner and odd-shaped cavity without gaps.
What it costs in North Tustin
Loose fill insulation over an existing layer in a North Tustin attic typically runs $1,500 to $3,800, depending on how much material we’re adding and the attic’s total footprint.
How we do it
We blow the material to the exact depth required for your climate zone and R-value target, using depth markers every few feet so the coverage is verifiable, not eyeballed.
What Blown In Insulation Costs in North Tustin
| Item | Typical range in North Tustin |
|---|---|
| Blown in cellulose (full attic, typical ranch) | $1,800 – $4,500 |
| Blown in attic insulation (full home) | $2,200 – $5,000 |
| Loose fill over existing insulation (top-off) | $1,500 – $3,800 |
These numbers reflect typical North Tustin attics in the 92711 ZIP code. Access, depth of existing material, and whether air sealing is included all move the final number. Every quote we give is upfront and fixed before any work starts.
How long does blown in insulation take in North Tustin?
A typical attic job finishes in one day. Larger split-levels or homes needing significant old-material removal can run into a second morning. We protect floors and work paths, and cleanup is complete before the crew leaves.
Can you blow insulation over old insulation in North Tustin?
Usually yes. If the existing material is dry and not compressed into the framing, we can blow new material directly on top to reach the target R-value. We remove anything wet, moldy, or so settled it blocks airflow before adding new material. Call (855) 795-2118 for a free inspection and exact quote.

What North Tustin 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."
— Mark Hoffman"Work is good and the house is noticeably more comfortable. There was insulation debris left in the hall closet under the attic access that I had to clean up."
— Keisha Jackson"Spray foam in the rim joists in the basement. The cold floors above them are gone."
— Danielle Schaefer
