Retrofit insulation in Perris, CA - an older house that holds its temperature

Most people who call us live in an older house that never feels right. It's hot upstairs by afternoon, nobody wants the room over the garage, and the power bill climbs every summer. I run Superior Perris Spray Foam Insulation here in Perris, and we work in the cities around it across western Riverside County. The price moves with the size of the attic, how many inches are already up there, how many gaps need air sealing before the insulation goes in, and whether anything has to be fixed first. The schedule turns on that same prep, and the written estimate I leave you puts your own numbers on both.

In an older house I start by finding out what's already up there and what shape it's in, because that tells us whether we add on top, fix things first or bring in a specialist. A Department of Energy guide says to check for a leaking roof, live knob and tube wiring, the old cloth-covered kind, vermiculite, and bath fans that blow into the attic, and to repair any of them before the retrofit goes ahead, so sometimes a fix comes first in your plan and your budget. Old insulation that's soaked or full of droppings comes out through our insulation removal work, since new material on top just buries the problem. Next we seal the openings in the attic floor with sealant, foam or rigid blocking, the step federal guidance puts first, and we fit metal blocking around hot flues and covers over can lights that aren't rated to touch insulation. Baffles go in at the eaves so the vents stay open and the attic keeps breathing. Then we blow in loose fill, cellulose or fiberglass sent through a hose, evenly across the whole ceiling and right out to the tops of the walls, where a lot of older attics are thinnest.

Retrofit work overlaps with our attic insulation service, since most of it happens in the attic. It also overlaps with spray foam insulation in houses where the ductwork runs through the attic and sealing it in is worth the extra cost.

California's energy standards have a section that applies when insulation goes into an existing attic, so a retrofit in Perris falls under the state rules the same way a new home does. The state Energy Code divides California into climate zones, and the standards for a home's walls, roof, windows and doors depend on the zone, so your house follows the standards set for the zone Perris is in. We plan the attic work to those standards. Federal guidance also says blown insulation should meet the current adopted codes or better, and we hold ourselves to that.

Most of what we see here is older houses that bake upstairs through a long inland summer, with thin, uneven insulation and gaps nobody sealed when the house was built. We find the same attics on jobs in Menifee and Moreno Valley, and we handle them the same way. We look first and insulate second.
