Insulation Company in Orange, CA
Blown in insulation solves a problem that Orange homeowners know well: rooms that bake in summer, attics that radiate heat into living spaces, and energy bills that climb every August. The right loose-fill material, installed at the right depth, changes how a house handles a 95°F afternoon. North Tustin Insulation has served Orange since 2011, and we match the material to your home, not the other way around. Call (877) 265-5712 for a free estimate on blown-in work in Orange.
Why Orange Homes Are Different
Orange splits into two distinct housing eras, and each one fails differently. Old Towne’s Craftsman and Spanish Colonial bungalows, built between the 1910s and 1940s, sit on plaster walls with minimal original insulation. Many of these attics have knob-and-tube-adjacent wiring, which means any blown-in job starts with careful wiring inspection, not just a hose in the attic. Two miles east, the 1960s and 70s tracts are full of original R-4 fiberglass batts that have slumped, compressed, and left wall cavities nearly empty. Those homes also tend to have DIY attic decking over the joists, which traps old insulation and blocks access until it’s pulled up. Orange sits in a semi-arid basin with hot, dry summers and Santa Ana winds in the fall. That means the priority is blocking summer heat gain from above, plus sealing against wind-driven dust and ember intrusion. Concrete, specific work, and it varies block by block.
Our Main Orange Services
Two services carry most of the calls we get from Orange: attic insulation overhauls and spray foam for hard-to-air-seal spaces. Here’s how each one works in this city.
Attic Insulation in Orange
The classic Orange attic job is a 1960s tract home with maybe four inches of crumbling fiberglass and a plywood deck screwed over half of it. We pull the decking, remove what’s there, air-seal the top plates and recessed light housings, then bring the attic to R-38 or R-49. In Old Towne, the job shifts: access is tighter, wiring is older, and the approach has to preserve original ventilation paths. For the full breakdown, see Attic Insulation in Orange.
Spray Foam Insulation in Orange
Spray foam earns its cost in Orange when a home has a low-slope roof, a converted attic, or a crawlspace that pulls in dusty Santa Ana air. Closed-cell foam from Demilec air-seals and insulates in one pass, which matters in older Orange homes where wall cavities are shallow and framing is irregular. Open-cell Icynene works well for attic roof decks when the homeowner wants the attic brought inside the conditioned envelope. Details here: Spray Foam Insulation in Orange.

Blown In Insulation in Orange
Blown in insulation is the workhorse retrofit for Orange’s housing stock. It fills wall cavities and attic floors faster than batts, reaches around old framing and wiring, and can be installed over existing insulation without demolishing plaster or drywall. If you own a 1950s bungalow in Old Towne or a 1970s tract home east of the 55, blown-in work is usually the most practical way to bring the home’s thermal performance up to something livable. We run GreenFiber cellulose and Johns Manville fiberglass through the machines, and every Orange job starts with the same question: where is the heat getting in? For a deeper look at the method, see Blown In Insulation.
Cellulose Insulation
Signs you need it
Rooms gain ten degrees by 4 p.m. and the attic smells like dust every time the AC kicks on.
What it costs in Orange
Blown-in cellulose in Orange typically runs $1.50 to $3.50 per square foot installed, depending on depth and access.
How we do it
We dense-pack wall cavities through small drilled holes or blow loose-fill across the attic floor to the specified R-value, then patch and finish every access point.
Blown In Attic Insulation
Signs you need it
Your AC can’t hold 78°F on hot afternoons and the ceiling feels warm to the touch by early evening.
What it costs in Orange
Attic-only blown-in jobs in Orange usually range from $2,000 to $5,500 for a typical single-story home, with two-story homes running higher.
How we do it
We ventilate the attic, air-seal penetrations, lay down a consistent loose-fill layer to reach R-38 or R-49, and install baffles at every soffit vent so airflow stays intact.
Blown In Fiberglass Insulation
Signs you need it
Old fiberglass batts have slumped below the joist tops, leaving bare spots across the attic floor.
What it costs in Orange
Blown fiberglass in Orange ranges from $1.20 to $3.00 per square foot installed, with deeper fills sitting at the higher end.
How we do it
We remove or level collapsed material, air-seal the attic plane, then blow loose-fill fiberglass to the target depth and verify coverage with a depth gauge.
Loose Fill Insulation
Signs you need it
Wall cavities are empty or barely filled, and the house can’t hold temperature in either summer or winter.
What it costs in Orange
Loose-fill wall retrofits in Orange typically cost $2 to $4 per square foot of wall area, including access hole work and patching.
How we do it
For walls, we drill access holes at each stud bay, dense-pack the cavity, then patch. For attics, we blow across the floor plane and level to the specified R-value.
What Blown In Insulation Costs in Orange
| Item | Typical range in Orange |
|---|---|
| Blown-in cellulose (attic, R-38) | $1.50 – $3.50 / sq ft |
| Blown-in fiberglass (attic, R-38) | $1.20 – $3.00 / sq ft |
| Loose-fill wall retrofit (dense-pack) | $2.00 – $4.00 / sq ft |
Is blown-in insulation worth it in Orange’s climate?
Yes, because Orange’s cooling season runs from May through October and attic heat is the biggest driver of indoor temperature gain. A properly air-sealed R-38 attic typically cuts cooling costs noticeably in the first summer. Call us for numbers on your specific home.
Can you do blown-in insulation in a historic Old Towne home?
Yes, attic-only blown-in work is usually straightforward and does not alter exterior appearance, so historic review is rarely triggered. Wall retrofits need more care around plaster and old wiring, but we’ve handled them throughout the district.
Brands We Service in Orange
We carry eight insulation brands across the major categories, and Orange jobs most commonly use GreenFiber cellulose, Owens Corning fiberglass, Johns Manville fiberglass, and Demilec spray foam. Parts and materials are stocked locally, which keeps most blown-in projects rolling without waiting on shipments. See our brands for the full product lineup.
