Cold floors over a damp crawl space or a hot room over the garage? We seal the leaks first, then spray foam that stays put.
Closed-cell foam insulation is a dense, rigid spray foam that insulates, seals air leaks and holds back moisture in one layer. In Seaside, CA we use it where those three jobs are worth paying more for.
Most people call Evergreen Seaside Spray Foam Insulation about cold floors over the crawl space, a hot room over the garage or a power bill that keeps climbing, and they've heard spray foam is the fix. The price moves with how much area we cover, how thick the foam goes, how hard the space is to get into and whether old insulation has to come out first, which is its own job we call insulation removal. The schedule turns on any repair that has to come first, a permit if the city wants one, and when your household can be away while the foam goes in and airs out. I put all of that into the estimate after I've seen the space, so you know what we'd do and why.
I come out myself, go up into the attic or under the floor, and write the estimate after I've looked, not from a phone call. That's where I find the roof stain, the old wiring or the wet insulation that changes what the job should be.
Before I started this business in Seaside in 2023, I spent years doing upkeep for a property management company. That's why landlords and property managers call us too, and why we fix problems in order instead of covering them with foam.
We're licensed and fully insured, and you're welcome to ask about it before we start. California's Contractors State License Board treats insulation as its own trade, covering contractors who install insulation to control heat or sound.
Our installers do the spraying, and when they're done I walk through it with you so you see exactly what we did and why. The work is backed by our satisfaction guarantee. To set up a visit, call (831) 204-4546 or use the form on this page.
Call (831) 204-4546 or send the form with the areas you want insulated, and we'll reply within one business day. I'll set a time to come out, look at the space and write a free on-site estimate, with no obligation to go ahead.
Seaside's building department takes permit applications and asks owners to check with it whether a building project or major repair needs a permit, so whether your foam job needs one is the city's call. Before we start, we check with the city or county building office for your address, and where a permit is needed, we take care of the paperwork and set up the inspections. The city works from the current California codes, including the energy code, with some changes of its own, and new projects have to meet them.
We're based in Seaside and work in cities across Monterey County, into Santa Cruz County and over to Gilroy, including Marina and Monterey. Around here we see a lot of older houses on raised floors, rentals with a few rounds of patch jobs in the attic, and rooms over garages that never got much insulation, and those are the places closed-cell tends to come up. If you're not sure we come out your way, just ask.
Closed-cell costs more than open-cell foam, mainly because it expands less and puts more material into every bit of space it fills. Your own figure comes from the estimate, after I've seen the space and know how much foam it really needs.
Yes. At the thickness it's usually sprayed, closed-cell foam is a vapor retarder, a layer that lets almost no water vapor through, while open-cell foam lets vapor pass. That means closed-cell can be the insulation and the moisture barrier in one layer. If we foam the underside of the roof and close off the attic, building guidance says that attic still needs a way to get moisture out, so we plan for it before we start.
Plan for the whole household to be out while the foam goes in and for at least 24 hours afterward, which is what consumer safety guidance tells homeowners. Anyone with skin conditions, respiratory allergies, asthma or a past reaction to isocyanates, the chemicals in spray foam some people become sensitive to, should read the product information carefully and may want a different kind of insulation. Tell me about it at the estimate, and ask us anything about how the crew handles safety.
Often it does, with a fire-protection layer such as a coating or drywall, but it depends on the foam. A thermal or ignition barrier goes over spray foam when the product or the code calls for one, and some foams don't need it. We check that for the product we'd use, so the covering is in the estimate and not a surprise.
The best way is to clear a path to the attic or crawl space and line up somewhere to stay for the time away. If there's a roof leak, old wiring or a pest problem up there, that gets fixed before any foam goes in, because foam over a problem just hides it. I'll go over what needs moving and what comes first when I'm out for the estimate.
