Drafty rooms, a hot upstairs or a cold room over the garage? We seal and insulate in one pass so the house stays comfortable.
Open-cell foam insulation is a spray foam our crew applies to attics, walls and other open framing in Rohnert Park, CA homes, where it seals air leaks and slows the heat and noise moving through the house.
Most people call us about a drafty bedroom, an upstairs that bakes all summer or the room over the garage that never feels right. Spray foam goes on wet, swells into the cracks and sets in place, so it closes the small gaps that leak air while it insulates. Loose insulation can't seal those gaps by itself, which is why foam is worth a look in some attics.
Here at T&S Rohnert Park Spray Foam Insulation, the price mostly depends on how much area we're covering, how easy it is to reach and whether old insulation has to come out first. The schedule depends on the weather, the city's permit review when one's needed, and when your household can be away for the install. You get a number for your own house at the estimate, once I've seen the space.
Spray foam is a bigger day than a bag of loose fill, so a few things get settled before we book. These are the ones I talk through with every homeowner.
Federal guidance for installers says spray foam needs the right air and surface temperature, humidity and a dry surface to go on properly. On a cold, damp stretch we may need to adjust the indoor temperature or move the day, so we'll go over the forecast and your thermostat before anything gets booked.
A tighter house lets in less of the outside air that normally clears cooking smells and other indoor odors. If a furnace, water heater or other fuel-burning appliance sits in the sealed area, federal guidance says it may need extra air exchange so combustion gases don't build up, and an HVAC designer is the right person to size that.
Federal guidance says the two-part, high-pressure foam system is professional equipment that only a trained applicator should use. Without skin, eye and breathing protection, spray foam chemicals can cause irritation and chronic lung disease, so the cans and low-pressure kits from the store are best kept for sealing small gaps.
From the first call to the walk-through, here's who does what. Most of the planning happens before the crew ever shows up, so install day goes the way you expect.
Call (707) 576-6028 or use the form and tell us which rooms are giving you trouble. We get back to you to set up a time for me to come out.
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, what I'd do first and what it would cost.
If a permit is needed, the city's Building Division reviews applications in the order it receives them, so we plan the start date around that wait. On the day, our crew protects your floors, handles the prep and installs the foam.
Before we pack up, I walk through the finished job with you and show you what went where. That way you know exactly what's up there now and what to tell the next person who opens the hatch.
Before we talk about foam at all, I ask whether anyone in the house has asthma, allergies or skin trouble. It's the first question because for some households the material matters more than who puts it in. If spray foam isn't a good fit for yours, I'll tell you that plainly and we'll look at other insulation instead of forcing the job.
The lead I worked under taught me to look at the whole house before selling anybody anything, and that's still how I plan foam. If the old insulation up there was soaked or full of droppings, it comes out first, because spraying over it just buries the problem. We also pay close attention to the edges and corners, where coverage tends to run thin.
Foam is one part of the house, and I'll point out anything else that needs attention while I'm looking. If your crawl space is bare dirt, a crawl space vapor barrier keeps ground moisture away from the underside of your floors, and it's worth a look while I'm down there. For shops, offices and other business buildings, we do commercial insulation too.
Foam costs more than loose fill, but when your ductwork runs through the attic it usually earns that price, because sealing and insulating the whole space keeps the ducts out of the summer heat up there.
In plenty of attics, air sealing, which closes gaps around can lights, pipes and the hatch, followed by a top-up of blown-in insulation, loose fill blown through a hose, does the job for less.
Send the form and we'll reply within one business day to set up a time for me to come out to your house. The estimate is free, done on site, and there's no obligation to book anything.
(707) 576-6028In Rohnert Park, the city's Building Division requires a permit for any construction, alteration or repair of a building. Its list of examples names reroofs and carports, not insulation, so that list alone doesn't settle whether your foam job needs one. We check with the Building Division before work starts, and when a permit is needed we apply for it, keep you posted and book the inspections through the city's online portal.
We're based in Rohnert Park and work across the cities around it in Sonoma and Marin counties. A lot of what we see is older attics with thin or tired insulation and rooms over garages that never got enough of it. It's much the same next door in Cotati and down the road in Petaluma.
I come out for every estimate myself, so the person who looks in your attic is the one who plans the job. Our crew does the work, with me on site or one of our lead installers running the day. I started out as a helper on a small insulation crew and opened this business in Rohnert Park in 2021, so we've been doing this for five years now.
We're licensed and insured. Federal guidance suggests asking any spray foam contractor about their training and checking their license and insurance before you hire, and I'm happy to answer those questions. Our work comes with one promise, satisfaction guaranteed. When you're ready, call (707) 576-6028 or send us a message and we'll set up a time.
If the space you want insulated is a shop, office or other business building, our commercial work is planned around your hours and the larger areas involved.
A bare dirt crawl space sends ground moisture up toward your floors, and a vapor barrier laid down there keeps the space under your house drier.
Our crew does spray foam work in the cities below and plenty of others nearby, so give us a call even if your city isn't on the list.
Federal guidance says you should be out of the house for at least 24 hours during spray foam work. Re-entry time, the point when it's okay to come back, comes only after the foam has finished curing and the house has been aired out and cleaned, so plan a place to stay for at least a day, and longer if your house needs it.
It may not be. Federal guidance says people with asthma, breathing allergies or skin conditions should carefully review the product information first and may want to consider other insulation. Tell me about it at the estimate, and we'll weigh the other options together before anything is decided.
We price every foam job after seeing it, because the number depends on what's in your attic right now. The size of the space, how cramped it is and how much old insulation has to come out all move it, and foam usually runs higher than sealing gaps and topping up loose fill. You'll get your figure at the estimate.
Sort out where everyone, pets included, will stay for the time away, and clear a path to the attic hatch or crawl space door so our crew can get in. We cover your floors and handle the rest of the prep, and we'll let you know ahead of time if anything stored in the space needs to move.
In Rohnert Park, only a licensed California contractor or the legal property owner can be issued a building permit. When your job needs one, we handle the application and the inspections, as described above, so you're not stuck doing the paperwork yourself.
Look for California's C-2 Insulation and Acoustical Contractor license, the class the state licensing board sets for contractors who install insulation for temperature or sound control. It's a fair thing to ask any contractor about before you book.
Call (707) 576-6028 or send the form with the rooms you want insulated and any health conditions in the household, so I come out ready to talk about the right insulation for your house.
