Insulation Company in Orange, CA
Blown in insulation is the most common retrofit we install in Orange, because so many homes here were built before cavity insulation was standard. Old Towne bungalows from the 1910s and 1920s have lath-and-plaster walls with no insulation at all, while east side ranch homes from the 1960s carry original R-7 fiberglass batts that have sagged into uselessness. On a July afternoon, attic temperatures in Orange climb past 130°F, and that heat pours straight through uninsulated ceilings. Call (866) 393-6041 and we’ll tell you which material actually fits your house, not just which one we happen to stock.
Why Orange Homes Are Different
Orange splits into two insulation realities. Around Old Towne Plaza and the streets feeding off Chapman Avenue, you have pre-1950 Craftsman and Spanish Revival homes built with balloon framing, lath and plaster, and no original wall insulation. We routinely find knob-and-tube wiring still active in those walls, which changes everything about how you insulate. You cannot blow cellulose or fiberglass around live knob-and-tube without creating a fire hazard, and the city’s historic design review limits what you can do to exterior walls anyway. The practical answer in much of 92866 is attic air sealing and loose fill above the ceiling plane, leaving the walls alone.
East of the 55 freeway, the picture flips. The 92867 and 92865 tracts are 1950s through 1970s ranch and split-level homes where the original fiberglass batts were installed to the code minimum of their era, often R-7, and have compressed to half that. These houses need a different approach: remove or top up the failed batts, seal the top plates and penetrations, and bring the attic to R-38 or better. Orange’s Santa Ana wind pattern and dry late summers make attic work the highest-return insulation job in this city, more than wall retrofits in most cases.
Our Main Orange Services
Most Orange homeowners call us for one of two things: an attic that needs new insulation after decades of R-7 batts failing, or a spray foam application where air sealing matters as much as R-value. Both are jobs we do in-house with our own crews.
Attic Insulation in Orange
Attic work in Orange is rarely just about adding material. In the east side tracts, we’re pulling out compressed 1960s fiberglass, air sealing the top plates and wire penetrations, and blowing fresh insulation to R-38 or R-49. In Old Towne, we work around original redwood joists and keep everything reversible where the historic designation requires it. The attic is where Orange homes lose the most conditioned air, and it’s the first place we look. Attic Insulation in Orange covers the full scope, from batt removal to radiant barrier.
Spray Foam Insulation in Orange
Spray foam makes sense in specific Orange situations: crawlspace encapsulation under older homes, attic rooflines where you want to bring ductwork inside the conditioned envelope, and rim joist sealing in homes with raised foundations. Closed-cell foam from Icynene or Demilec creates an air barrier and thermal barrier in one application, which matters when Santa Ana winds push dust and hot air through every gap. But we’ll also tell you when spray foam is the wrong choice, including much of the Old Towne historic core where reversibility matters. Spray Foam Insulation in Orange explains the material options and where each fits.

Blown In Insulation in Orange
Blown in insulation is the workhorse retrofit for Orange attics, and it’s the right call for most homes built before 1980. In the east side tracts, we blow loose fill over the top of failed R-7 batts to bring the attic to R-38 or R-49. In Old Towne, we blow cellulose into attic floors above historic ceilings, working around the original redwood framing and leaving the walls untouched where knob-and-tube wiring makes wall retrofit unsafe. Loose fill also lets us hit odd-shaped attic cavities and low-slope roof bays that batts cannot reach. That’s the core of our Blown In Insulation work in Orange: a fast, cost-effective attic upgrade that respects the house’s existing structure.

Can you blow insulation into walls that have knob-and-tube wiring?

In Orange, the biggest price variables are attic access and the condition of what’s already up there. A 1920s Old Towne attic with low clearance, original redwood framing, and knob-and-tube wiring takes longer and costs more than an open 1960s tract attic. We give an upfront price before any work starts, and that number doesn’t move unless the scope changes with your sign-off.

— Rafael Garcia"Told me the crawlspace didn't need doing and only the attic did. Half the job, half the money."
— Hector Hernandez"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."
