How we handle insulation in Petaluma
Any insulation crew you hire should look before they quote, tell you what's actually up there and do the work in an order that makes it pay off. Here's how we handle each of those.
Gaps sealed first
We close the gaps where attic air leaks into the house before new insulation goes in, so it isn't fighting a draft and your house actually feels warmer.
Estimates from the owner
The person who writes your estimate is the one who climbed into your attic, so the price comes from what's up there, not a guess from the driveway.
We say what can wait
We tell you what we find, like old insulation that's soaked or full of droppings, and what can wait, even when that means a smaller job for us.
Even coverage, open vents
We run insulation full depth out to the edges and keep the eave vents clear, so the attic keeps breathing and moisture doesn't settle in the framing.
Curious what's going on in your attic? Get in touch or call (707) 238-6044, and I'll come take a look.
Insulation contractor services in Petaluma, CA
Evergreen Petaluma Spray Foam Insulation is an insulation contractor in Petaluma, CA, and our 16 services cover everything from a hot upstairs to cold floors over a crawl space, so your house feels warmer and quieter. The price mostly turns on how much space there is, how easy it is to get into, what's already up there, whether old material has to come out first and whether you go with foam or loose fill. The schedule turns on the same things, plus whether the city wants a permit for your job. I'll give you your own figure when I come out for the estimate.
Spray foam insulation
We spray foam into rafters, walls and crawl space framing, where it expands to fill the cavity and seals air while it insulates, good for tight, odd-shaped spaces.
Learn moreAttic insulation
Hot upstairs in summer, chilly in winter? That's usually a thin attic, and we bring it to an even depth across the whole floor, edges included.
Learn moreBlown-in insulation
Blown-in insulation is loose fill blown through a hose, and we use it to top up attics or fill closed walls through small holes.
Learn moreHome insulation
Not sure where the drafts are coming from? We look at the attic, walls and crawl space together and tell you which one is worth doing first.
Learn moreInsulation removal
When old insulation is soaked, matted or full of droppings, we pull it out and clean up the attic so new material isn't sitting on the old problem.
Learn moreCrawl space insulation
Cold floors over a crawl space usually mean bare or sagging insulation underneath, so we seal the gaps and fit new insulation snug under the floor.
Learn moreWall insulation
Older houses often have little or nothing in the walls, so we blow insulation in through small holes and patch them when we're done.
Learn moreAir sealing services
Air sealing means closing the gaps around pipes, wires, can lights and the attic hatch, and we do it before insulating so the house stops pulling in drafts.
Learn moreBasement insulation
For a basement that stays damp and chilly, we insulate the walls and the framing above them with material that handles moisture, so the room is more comfortable.
Learn moreClosed-cell foam insulation
What is closed-cell foam? It's a dense foam that blocks moisture and air, and it's our pick where dampness matters, like crawl spaces and basement walls.
Learn moreOpen-cell foam insulation
Open-cell foam is softer than closed-cell, and we spray it under roofs and in walls where you want air sealing and quiet more than a moisture barrier.
Learn moreCommercial insulation
We insulate offices, shops and rental buildings for owners and property managers, and we plan the work around your tenants and business hours.
Learn moreCrawl space vapor barrier
A crawl space vapor barrier is a heavy plastic sheet laid over the dirt and sealed at the seams, so ground moisture stays out from under your floors.
Learn moreVapor barrier installation
We install vapor barriers in walls, basements and other spots where damp air would otherwise reach the insulation and framing, keeping both drier over time.
Learn moreAttic air sealing
Feel air coming through the attic hatch? We seal the gaps in the attic floor from above, so heat stops slipping out of the rooms below.
Learn moreRetrofit insulation
Retrofit insulation adds insulation to a house that's already built, like the room over the garage, and we work around finished walls and your furniture.

How an insulation job goes with us
Call or send the form
Call (707) 238-6044 or send the form and tell us what's bugging you, whether it's a hot upstairs, cold floors or a power bill that keeps climbing. We get back to you within one business day and set up a time for me to come out and see the house.
I look and explain
I go up in the attic or down in the crawl space, check how many inches are already there and what shape they're in, and talk through what I see in plain words. Then you get a free estimate with no obligation, including anything I think should be fixed first and anything that can wait.
Our crew does the work
If you go ahead, our crew lead and installers do the job in the order we went over at the estimate. They cover your floors on the way to the attic or crawl space and clean up as they go, so you're not left with a mess when they pack up.
We check it together
When the crew's finished, I come back and go over the work with you, up in the attic or crawl space if you'd like to see it for yourself. We don't call the job done until we've checked it together and you've had a chance to ask whatever's on your mind.
Insulation questions we hear most
Here are straight answers to what Petaluma homeowners ask us before an insulation job. If your house raises a question that isn't here, ask me when I come out.
How much does attic insulation cost in Petaluma?
It depends on the size of your attic, how many inches are already up there and whether the old insulation has to come out first. A tight attic with a small hatch takes longer to work in, and spray foam costs more than blown-in loose fill. I'll give you your own number when I come out for the estimate.
Is spray foam worth the extra cost over blown-in insulation?
Usually not on a regular attic floor, where sealing the gaps and topping up the loose fill tends to win. Foam costs more because it seals air while it insulates, and it earns that price when your ductwork runs through the attic. I'll tell you which way I'd go for your house and why.
How long will an insulation crew be in my attic?
That depends on how big the attic is, how easy it is to get into and whether old insulation comes out first, so I'll give you a realistic idea once I've been up there. A simple top-up is a much smaller job than pulling everything out and starting over.
Do I have to leave the house while you spray foam insulation?
For spray foam, usually yes, and we tell you ahead of time when you need to be out and when you, the kids and the pets can come back in. That wait is the re-entry time, the hours before it's time to go back inside, and it depends on the product. For blown-in and air sealing jobs, you can usually stay home.
Do I need a permit for insulation work in Petaluma?
It depends on the job, so we check what the city wants before we start instead of guessing. The City of Petaluma issues permits for work like water heaters, solar panels, decks and home renovations, and we handle the permit when your job needs one. If you'd like to ask the city yourself, building permit questions go to building@cityofpetaluma.org.
What's the difference between closed-cell and open-cell spray foam?
Closed-cell is dense and blocks moisture as well as air, while open-cell is softer and lets moisture pass through. That's why closed-cell suits damp spots like crawl spaces and open-cell suits walls and roofs where quiet and air sealing matter more. On a lot of attic floors, plain blown-in insulation is still the better buy.
Why is my upstairs so hot in the summer in Petaluma?
Usually because hot attic air is leaking into the rooms below through gaps in the ceiling, and the insulation up there is thin or uneven. In older houses around Petaluma we often find a few inches that have settled over the years, with nothing sealed around the lights, pipes and hatch. Sealing those gaps and evening out the coverage is usually the change you'll feel most.
What if something doesn't feel right after my insulation is done?
Call us at (707) 238-6044, tell me what you're noticing and I'll talk it through with you. Before we call any job done, I go over the work with you, so most questions get answered right there in the attic. Your satisfaction, guaranteed.
