Spray foam insulation in San Clemente CA - an attic sealed and insulated in one pass

Most calls I get are about an upstairs that's hot by afternoon, a room over the garage that never feels right, or a remodel coming up that'll open the walls. Foam can fix a lot of that, but if it goes over old insulation that's soaked or full of droppings it just seals the problem in, so sometimes insulation removal has to come first. The price turns on how much area we're covering, how thick the foam goes, how tight the space is to work in and whether anything has to come out first. The schedule turns on that prep and on how long your household needs to be out while the foam cures. Your estimate lays all of it out step by step, so you can see what comes first and why.

It starts at the estimate. I ask whether anyone in the house has asthma, allergies or skin trouble, and I get you the product information for the foam we'd use so you can read it before you decide, because that's your call to make. If you go ahead, we plan the time you'll be out of the house around that product's own guidance, not a number we picked. On the day, our crew clears the space, covers anything that shouldn't get foam and closes the work area off from the rest of the house so the spray stays where it belongs. Then we spray in passes and keep the depth even all the way out to the edges, because the edges are where it's easiest to go thin. We clean up, check the coverage, and you come back when the product's guidance says you can.

Foam isn't always the answer, and I'll tell you so. It costs more, and in a lot of attics, air sealing, which means closing the gaps around lights, pipes and the hatch, followed by a top-up of blown-in insulation, loose fill blown through a hose, does the job for less. Where foam usually earns its price is an attic with the ductwork running through it. If you're weighing both routes for the whole space, our attic insulation work covers the loose-fill side.

Whether your foam job needs a building permit is up to the city, and it isn't something I'd guess at. When a job calls for one, we pull it as the licensed contractor and handle the inspections, and if I'm not sure about a job, I check with the city before we start. If you'd rather ask yourself, the City of San Clemente takes building permit applications, and its Community Development Liaison answers permitting questions at 949-361-6100. Insulating an existing house still falls under California's Energy Code, which sets efficiency requirements for alterations as well as for new homes, so an older house is still held to state rules.

In San Clemente attics we see a lot of ductwork running through the space, recessed lights and pipes coming through the ceiling with gaps around them, and older insulation that's settled thin or been torn up by animals. We're based here and work in cities across south Orange County, and we find the same kinds of attics on jobs in Dana Point and San Juan Capistrano.
