Cold floors over the basement, or a musty lower room? We sort out the damp, then insulate the walls so the space stays comfortable.
Basement insulation in Seaside lines your foundation walls, the part of the house that sits below the ground, so the basement holds its warmth better and the floors above it don't feel as cold.
Most people call us because the room downstairs is cold, it smells damp, or they want to turn it into living space. The price moves with how much wall there is, whether a water problem has to be fixed first, which foam fits your walls, and whether that foam gets painted or covered with drywall. The schedule mostly turns on that water repair and on whether your building office wants a permit, and you'll get your own figure when I come out, measure the walls and write the estimate. If your house sits over a crawl space instead, that's a different job, and our crawl space insulation work covers it.
I come out myself to look at the basement, check the walls for water and measure before I quote anything. Our installers do the work, and when they're finished I walk through it with you so you know exactly what went on your walls and why.
We're licensed and fully insured, so you aren't the one carrying the risk while our crew is working in your house. If you want to see the paperwork, ask when I come out and I'll show you before you sign anything.
I started this business in Seaside in 2023 after years of upkeep work for a property management company, crawling under a lot of floors. That's where I learned that insulation laid over a problem just hides it. Call (831) 204-4546 or use the form to have me look at yours.
We reply within one business day, and I come out to look at the walls and write the estimate myself, free and with no obligation. It helps if you know the basement's size in square feet, any signs of water you've seen, and whether the space is lived in.
In Seaside, the city's Building Department recommends that owners contact it before any building project or major repair to find out whether a permit is needed, so whether your basement job needs one isn't settled until the city says. 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. Work here has to meet the California codes plus the city's own changes to them, and the city's applications and forms page lists an Insulation Requirements sheet for owners and contractors if you'd like to read it.
If you want to read about radon, the state Department of Conservation lists a report called Radon Potential in Monterey County, California. We're based in Seaside and work in cities across Monterey County, into Santa Cruz County and over to Gilroy, including Monterey and Marina, and if you're not sure we come out your way, just ask. The basements we see run from a small room under part of the house to a full finished lower floor, and in every one I start at the walls.
Yes, any water coming through the walls should be fixed first, and federal energy guidance written for the whole country says to then steer bulk sources of moisture away from the foundation walls. That means a damp basement pays for its repair before any insulation goes in. I'll tell you what I see at the estimate, and the repair comes before our crew starts.
Closed-cell spray foam is usually the first choice, because federal research found it gives the best moisture control of any insulation used inside foundation walls. Open-cell foam has to go on thicker to hold back vapor, so on damp walls I'd look at closed-cell first. That research covers the whole country, so I still check your walls before recommending either one.
Federal guidance says fiberglass batts and cellulose should stay out of contact with foundation walls. It also says plastic sheeting or foil-faced board shouldn't go on the room side of fibrous insulation in a basement, because it can trap moisture inside the wall. It suggests kraft-faced batts, the ones with a paper backing, or latex paint on the drywall instead.
Across the US, insulating a basement usually costs about $4.40 to $6.40 per square foot, and that's a national figure, not our price. Your own figure comes from the estimate, where I measure the walls and price the foam's covering in from the start.
The install itself is usually the short part, and most of the time goes into getting the walls ready. If water needs fixing or a permit is needed, that comes first and sets the start date. Spray foam also has a re-entry time, the wait before you go back into the space, and I'll tell you what it is for your job before we start.
In most cases, yes. The state licensing board sets a $1,000 limit for small jobs someone can do without a license, and that only applies when the work needs no permit and the person employs no one. Anything past that line needs a licensed contractor, so it's fair to ask anyone you're considering to show theirs.
