Hot upstairs rooms, drafts and a power bill that keeps climbing? We match the foam to the spot so it seals and insulates.
Spray foam insulation is foam we spray into the attic, roofline or crawl space of your Rohnert Park house, where it fills the gaps that make rooms drafty and slows heat at the same time, so one product does two jobs.
Most calls start with a room that won't hold its temperature: hot upstairs in summer, cold floors over the crawl space, or the room over the garage nobody wants to sleep in. Usually the cause is air leaking through gaps around pipes, can lights and the attic hatch as much as thin insulation, and that's where foam earns its keep, because it seals those gaps as it goes on.
What moves the price is where the foam goes, how much area it covers, which foam fits that spot and how tight the space is to work in. The schedule turns on the weather and temperatures the foam's maker calls for, and on when your household can be away. Your own number comes from the estimate at your house, once I've seen what's up there.
Spray foam works best when the space is ready for it. These are the things I look at on every estimate, because each one changes how the job goes and what it costs.
I start by measuring how many inches of insulation are already up there and checking what shape they're in. If the old material was soaked by a roof leak or is full of rodent droppings, covering it just buries the problem, so it usually comes out first through our insulation removal work.
The places that leak most are the hardest to reach: down at the eaves, around the attic hatch, and where pipes, wires and can lights come through. A job that's thick in the middle and thin at the edges is backward, so our crew works those corners carefully, since that's where the drafts you feel get in.
A house's age tells me a lot before I climb up. Older houses usually have more gaps, thinner or settled insulation and framing that's been patched over the years, which means more prep before spraying. Newer houses tend to go quicker, though a room over the garage or a crawl space can still surprise us.
Here's how a spray foam job runs with us, from your first call to the walkthrough, including the planning for your household's time away from home.
Call (707) 576-6028 or use the form and tell us where you're thinking of putting foam. We'll set up a time that works for you so I can come look at the house.
I come out myself, go up into the attic or down into the crawl space and take photos. Then we sit down together, and I show you what I found and what I'd do first.
We book the day once the foam and your time away are settled, and if a permit's needed we apply first, since the city reviews applications in the order received. Our crew protects your floors and handles the prep and spraying.
Before we pack up, I walk through the finished work with you and show you where the foam went. If there's a permit, we set up the inspection through the city's online portal.
The first thing I want to know is where the foam is going, because the foam that suits the underside of a roof deck may not suit a crawl space. So we settle the foam type with you up front, and we plan the time your household spends away from home before we put the day on the calendar, not the week of.
I'll also tell you when foam isn't the best buy. It costs more than loose fill, and it seals air while it insulates. If your ductwork runs through the attic, foam under the roof deck is usually worth it, because it brings those ducts inside the insulated part of the house. If not, sealing the gaps and topping up the floor with loose fill blown through a hose, what we call blown-in insulation, often wins. Our attic insulation work covers that route.
Sprayed on the underside of the roof, it seals and insulates the attic as one space. It makes the most sense when ductwork or a furnace lives up there, and it's the pricier choice.
We close the gaps around pipes, lights and the hatch, then blow fresh loose fill across the attic floor. It's usually the better buy when nothing important runs through the attic.
We reply within one business day to set up a time. I come out for a free estimate at your house, and there's no obligation to go ahead.
(707) 576-6028In Rohnert Park, the city's Building Division issues permits for new construction, additions, alterations, repairs and demolition, and the jobs its list names are things like reroofs, fireplaces, pools and carports, not spray foam. That list doesn't settle whether your job needs one, so we check with the city before work starts. When a permit is needed, we apply for it, keep you posted and set up the inspections. The state Energy Code also sets efficiency requirements when an existing house is altered, not just for new homes.
Around here we get a lot of the same calls: a two-story house that runs hot upstairs, a room over the garage that never feels right, or an old attic someone has meant to deal with for years. We're based in Rohnert Park and do the same work across the cities around it in Sonoma and Marin counties, including Cotati and Petaluma.
I come out for every estimate myself, so the person who climbs into your attic is the one who plans the job. I started as a helper on a small insulation crew, hauling bags through attics, and the lead I worked under taught me to look at the whole house before selling anybody anything. I opened this business in Rohnert Park in 2021, and we've been at it five years now.
Our crew does the work, with me on site or one of our lead installers running the day. I'll explain what's going on up there in plain words, so you understand your own house. We're licensed and insured. Our work comes satisfaction guaranteed. When you're ready, call (707) 576-6028 or send us a message.
If foam on the roofline isn't the right fit, insulating the attic floor can fix a hot upstairs for less, and we'll lay out both options side by side.
Loose fill blown across the attic floor tops up thin old insulation quickly and works well once the gaps underneath have been sealed tight.
Besides Rohnert Park, these are the cities with their own page on our site. If yours isn't listed, call anyway, because we work in plenty of other places nearby too.
There's no set price for spray foam, because each house gets measured on its own at the estimate. Spray foam may also need a covering called a thermal or ignition barrier, such as a coating or drywall, depending on the foam and what code requires, and that adds to the job. Removing old insulation first changes the total too.
Either type can go under a roof deck, but they don't do the same job. Open-cell foam insulates, while closed-cell foam, the denser kind, insulates and also acts as the vapor control layer that manages moisture, so one product covers both. Our closed-cell foam page goes into the denser kind.
Usually not on the foundation walls. One building guide found open-cell foam often doesn't suit below-grade spots like basement and crawl space foundations, because moisture passes through it, and moisture is very hard to control down there. That's why the foam type for a crawl space gets decided before anyone starts spraying.
Plan on at least 24 hours. Consumer safety guidance advises leaving the home during the install and for at least 24 hours after, and talking through the safety steps with your contractor ahead of time. Line up a place for everyone to stay, kids and pets included, before the day is booked.
In Rohnert Park, only a licensed California contractor or the legal property owner can be issued a building permit. If your job turns out to need one, we handle the application and inspections, as covered in the permits section above, so you don't have to chase it yourself.
Yes. California's C-2 Insulation and Acoustical classification covers contractors who install any insulating material for temperature or sound control. Spray foam falls under that the same way fiberglass batts and loose fill do, so the same license rules apply to a foam job.
Call (707) 576-6028 and mention anyone at home with asthma, allergies, skin conditions or an earlier reaction to isocyanates, a chemical in the foam, since safety guidance says they should look over the product information carefully first.
