Evergreen Seaside Spray Foam Insulation does attic insulation, spray foam and air sealing in Seaside and nearby cities like Monterey and Marina. We also remove old, tired insulation and insulate crawl spaces under older houses with cold floors.
A quote over the phone is a guess, because nobody knows what's under the old layer until they've been up there. We get into the attic, walls or crawl space first, so the plan you get is built on what we actually found.
Sealing the gaps comes first, then the insulation goes in, so you're not paying for a layer that fights a draft. We also keep the eave vents at the roof edge clear, because a buried vent stops the attic breathing and moisture ends up in the framing.
If your roof leaks or the old wiring needs an electrician, I'll tell you to fix that first, because insulation laid over a problem only hides it. You'll get that plain answer even when it means less work for us.
I spent years doing upkeep for a property management company, crawling through attics and under floors and seeing what tired insulation and leaky houses do to the people living in them. I started this business in Seaside in 2023 to do that work properly instead of patching around it, and those years taught me to work clean and treat the people living there with respect, whether it's your own house or a rental you manage.
We're licensed and fully insured, and every job is backed by our satisfaction guarantee. That license matters in California, because the Contractors State License Board requires one for work that needs a building permit, uses any hired workers or totals $1,000 or more in labor and materials.

Evergreen Seaside Spray Foam Insulation is an insulation contractor in Seaside offering 16 services, from the attic down to the crawl space. The price mostly turns on how much space we're covering, how many inches are already up there and whether old material has to come out first, and the schedule turns on that same cleanup plus any permit the job needs. Foam costs more because it seals air while it insulates, but sealing the gaps and topping up blown-in insulation, loose fill blown through a hose, usually wins unless your ductwork runs through the attic. Your free on-site estimate gives you the figure for your own house.
Spray foam goes on wet, expands to fill gaps and cracks, and seals air while it insulates, which suits rooflines, rim joists and tight spots where loose fill can't reach.
Explore service: Spray foam insulationHot upstairs or drafty all through the house? We check how many inches are already up there and bring the whole attic to an even depth, edges included.
Explore service: Attic insulationWe blow loose fill through a hose into attics and closed wall cavities, a fast, tidy way to top up thin coverage without tearing anything open.
Explore service: Blown-in insulationWhen the whole house feels drafty and the power bill keeps climbing, we look at the attic, walls and floors together and fix them in the right order.
Explore service: Home insulationOld insulation that's been soaked, packed down or filled with rodent droppings has to go before anything new goes in, so we bag it out and leave the space clean.
Explore service: Insulation removalIs the floor cold under your feet? Often the crawl space below is bare or the old batts have dropped, so we insulate between the floor joists and close it up.
Explore service: Crawl space insulationOlder walls are often empty inside. We drill small holes, fill each cavity with blown-in or foam, then plug the holes, so rooms along outside walls stop feeling chilly.
Explore service: Wall insulationDrafts at outlets, baseboards and around windows? We find where outside air sneaks into the house and close those gaps with foam and caulk, room by room.
Explore service: Air sealing servicesWe insulate basement walls and the rim joist, the band of wood where the house sits on the foundation, so a basement you actually use stops feeling like a cellar.

Explore service: Closed-cell foam insulationWhat's the difference from closed-cell? Open-cell foam is lighter and softer, seals air well and muffles sound, and usually costs less, which makes it a good fit for rooflines and interior walls.
Explore service: Open-cell foam insulationWe insulate offices, shops and small commercial buildings, and we can work around your hours and keep the work area clean so tenants and customers carry on.
Explore service: Commercial insulationWe lay heavy plastic sheeting over a dirt crawl space floor and up the walls, tape the seams and fasten it down, so ground moisture stays out of the house.
Explore service: Crawl space vapor barrierIn walls, attics and under floors, a vapor barrier keeps moisture from working into the insulation, and we put it on the side where it does its job instead of trapping water.
Explore service: Vapor barrier installationBefore insulation goes in up top, we seal the attic floor around can lights, plumbing stacks, wiring holes and the hatch, so the house stops pulling attic air into the rooms below.
Explore service: Attic air sealingAdding insulation to a house that's already built and lived in is retrofit work. We get it into existing attics, walls and floors with as little opening up as the job allows.
Explore service: Retrofit insulationCall us or send a few lines through our contact page about the rooms that feel drafty or hot, and we'll get back to you within one business day to set a time to come out.
I come out myself and look at the attic, walls or crawl space, note anything that has to be handled first, and write up a plan and estimate you can read in one sitting. It's free, and there's no obligation.
Once you say yes, we check with the building office for your address, in Seaside the city's Building & Code Enforcement Department, and handle the paperwork where a permit is needed. Our installers do the work and clean up, and I walk through it with you before we call it finished.
Send the form or call (831) 204-4546, and we'll reply within one business day to set up a time for me to come look. The estimate is free and done on site, and there's no obligation to go ahead.
