I started Evergreen Seaside Spray Foam Insulation here in Seaside in 2023, after years of upkeep for a property management company that had me crawling through attics and under floors. We insulate Seaside homes and rentals, and we seal the leaks first so the new insulation can actually do its job.

Seaside is our home base, and our calls here come from homeowners and also from the landlords and property managers who look after the city's rentals. A lot of these houses are older and have been lived in hard, so the attic often has a few inches of old insulation that's packed down, patched in spots and thin at the edges, and nobody has been in the crawl space in a long time.
The complaints are usually the same: a hot upstairs, a cold room over the garage, cold floors or a power bill that keeps climbing. Most of the time that traces back to air getting in and tired insulation, not the heater, and we find the same thing up the road in Marina.
Call (831) 204-4546 or send the form and tell us what you're dealing with, like a drafty room or cold floors. We reply within one business day to set a time, and I come out to your Seaside house myself to look at the attic or crawl space and write the estimate. It's free, and there's no obligation to go ahead.
(831) 204-4546Most of our Seaside work happens in attics and crawl spaces. In the attic we start with air sealing, closing the gaps around lights, pipes and the hatch, then add blown-in insulation, loose fill blown through a hose, so the edges end up as deep as the middle. Under raised floors we insulate between the joists and put down a vapor barrier where the crawl space calls for one. We also pull out old insulation that's wet or full of droppings, because new material laid over it just hides the problem, and where ducts run through the attic or a wall needs filling, spray foam insulation is often the better fit.
In Seaside, whether an insulation job needs a permit is the city's call, made by its Building & Code Enforcement Department, which asks owners to check with it before any building project or major repair. We make that check for your address before we start, and where a permit is needed we take care of the paperwork and set up the inspections, so your start date can hang on that step. You can check two things on any contractor here: a California contractor's license and a Seaside business license, which the city issues each year. We're licensed and fully insured.
What moves the price is mostly what's already there: how many inches are in the attic, whether the old material is wet or dirty and has to come out first, how many gaps need sealing, and how tight the space is to work in. The schedule turns on the same things, plus any permit and any repair that has to happen first, and the estimate I write after looking spells out what we'd do and why. We see the same kinds of houses in Salinas and Monterey, and we handle them the same way.
I come out myself and get into the attic or crawl space, checking how deep and how clean the old insulation is and where air is getting through. That way the estimate covers the job your house actually needs, including anything that has to come out first.
If I find a roof leak, old wiring or soaked insulation, I'll tell you to deal with that before we add anything, even if it means a smaller job for us today. Insulation laid over a problem only hides it, and you'd end up paying twice.
Our installers do the work, and when they're done I walk through it with you, showing what we sealed, how deep the new insulation is and that the vents along the roof edge are still clear. Backed by our satisfaction guarantee. Call (831) 204-4546 or use the form.
I can't give you an honest figure until I've been up in your attic, because the price turns on what's already there and what has to come out or be sealed first. Sealing the gaps and topping up loose fill usually costs less than spray foam and is the better buy for most attics. Foam costs more because it seals air while it insulates, so it mostly earns its price when your ductwork runs through the attic, and I'll tell you which way I'd go and why.
The time in your attic depends on its size and whether old insulation has to come out first, and I'll tell you what to expect when I come out to look. For air sealing and blown-in work you can usually stay home. Spray foam is different, because everyone, kids and pets included, stays out until the re-entry time, when it's safe to come back in, which the foam maker sets.
Ask the city's building department, either at the Permits & Inspections counter in City Hall or by email at building@ci.seaside.ca.us, which is also where it takes applications. If we're doing your job, we make that check for your address before we start, so you don't have to.
Yes, whenever the job needs a building permit, uses any workers besides the contractor, or the labor and materials come to $1,000 or more, because that's when the Contractors State License Board requires one. A larger job can't be split into smaller contracts to get under $1,000. Ask to see the license before you sign anything.
Projects submitted in Seaside now have to meet the 2025 California codes the city has adopted, along with its own local amendments. That set took effect on January 1, 2026, and includes the energy code as well as the building, residential, electrical and mechanical codes, so we plan the work to meet them from the start.
