Drafty rooms, a hot upstairs or cold floors? We find where your house loses heat and fix it in the order that pays off.
Home insulation in Rohnert Park means adding insulation to your attic, floors and crawl space and closing up the air leaks around the house, so your rooms stay closer to the same temperature and your heating and cooling don't have to work as hard.
Most calls we get at T&S Rohnert Park Spray Foam Insulation start with a complaint, not a plan. The upstairs is hot by afternoon, the room over the garage never warms up, the floors are cold or the power bill keeps creeping. Usually it's more than one spot, and the fix runs through the attic, the crawl space and sometimes the walls.
The price turns on how much house we're covering, how many inches are already up there, whether old material has to come out first and how easy the attic or crawl space is to reach. Foam costs more than loose fill. The schedule moves with the same things, plus any wiring or moisture problem that has to be handled before we start.
The age of your house tells me a lot before I even climb up, since older homes often have thin, settled fill or nothing in the walls. Still, your own number comes from the estimate. When I come out, I'll show you photos of what I found and tell you what I'd do first.
Before anything gets ordered, a few things about your house shape the plan. These are the ones I check when I'm up there, and they're worth knowing before you call.
Walls can take batts, blown-in fiberglass or cellulose, which is loose fill blown through a hose, or spray foam. Attics and roofs can use those plus rigid foam boards. Because the right pick depends on where it's going, we weigh the options for the walls and the attic separately instead of selling one product for the whole house.
Before anything new goes in, these need a professional fix: wet insulation, moldy framing, a vent blowing damp air into the attic, poor ventilation, and old knob and tube wiring, the cloth-covered kind from older houses. The wiring matters most, because it can be a fire hazard when insulation touches it.
If you have a gas furnace or water heater, closing up the attic's gaps before insulating, what we call air sealing, can change how those appliances vent. In some cases a tighter house sends combustion gases back inside, so it's worth having them tested for proper drafting before and after the sealing, whoever you hire.
Here's how a job runs from your first call to the walk-through, and who you'll deal with at each step. Nothing gets installed until you've seen what's up there.
Call (707) 576-6028 or use the form, and we'll get back to you to set a time. It helps to tell us how you reach the attic, whether you have gas appliances and whether you've spotted gray, flaky fill up there.
I come out myself, go up into the attic or down into the crawl space and take photos. Then we sit down together, I show you what I found and lay out what I'd do first.
If the job needs a permit, the city reviews applications in the order they come in, so that can set the start date. On the day, our crew protects your floors, handles the prep and does the install.
Before we pack up, I walk through the finished work with you so you can see what went in where and ask anything. You'll know what your house has now and what, if anything, makes sense down the road.
When you want the whole house done, I look at the attic, the floors and the walls together and lay out which job should come first. That way each step sets up the next one, and you're not paying to pull out something that went in last year because the order was wrong.
If the old insulation is soaked or full of droppings, it has to come out before anything new goes on top, or the problem just stays put. That's where insulation removal fits in. Cold floors usually trace back to what's under them, so crawl space insulation often makes the list for rooms over the crawl space.
Up in the attic, the steps nobody sees matter most to me. We seal around can lights, pipes and the hatch before the insulation covers them, keep the eave vents clear so the attic can breathe, and carry the coverage full depth out to the edges, where it so often runs thin.
Spray foam costs more and seals air while it insulates. For most attics, sealing the gaps and topping up with loose fill gets you more for the money, unless your ductwork runs through the attic, where foam usually earns its price.
You don't have to do the whole house in one go. If the budget says stages, we start with the job that sets up the others, usually the attic or the crawl space, so nothing gets torn out later.
Send the form and we'll reply within one business day to set a time that works for you. The estimate is free, done at your home, and there's no obligation to book anything.
(707) 576-6028Permits here go through the city's Building Division. It issues them for new construction, additions, alterations, repairs and demolition, and its list calls out reroofs, fireplaces, pools and carports without naming insulation. So the list alone doesn't tell you whether your job needs one.
We check with that office before work starts. If a permit is needed, we apply for it, keep you posted and set up the inspections, which the city books through its online portal. If you'd rather ask yourself, the city's building staff take calls at 707-588-2240.
We're based in Rohnert Park and work across the cities around it in Sonoma and Marin counties, including Cotati and Santa Rosa, plus plenty of others nearby. The calls are much the same everywhere we go, a hot second floor, a chilly room over the garage, or an older attic with a few settled inches that someone's been meaning to deal with for years.
I started out hauling bags and crawling through attics on a small crew, 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, so we've been at it five years, and that lesson is still how I run every estimate.
Our crew does the work, with me on site or one of our lead installers running the day. We're licensed and insured, and if I think something isn't worth the money, I'll tell you so. I'd rather you understand what's going on in your own attic than just take my word for it. Satisfaction guaranteed.
If there's a room in your house that never feels right, or an attic you've been putting off, that's a good place to start. Send us a message or call (707) 576-6028, and we'll find a time to come take a look.
Worth it when the old fill in your attic is wet, matted or full of droppings, since new insulation laid on top just buries the problem.
A good fit if your floors feel cold all winter or the rooms over the crawl space never seem to warm up, no matter where the thermostat sits.
Besides Rohnert Park, we insulate homes in the cities listed below and in plenty of others nearby across Sonoma and Marin counties. If you don't see yours, give us a call and ask.
Attic insulation in the Santa Rosa area usually runs about $1,700 to $5,500 per job, and that's the going rate around here, not a quote from us. Where your attic lands depends mostly on its size and what has to happen before new insulation goes in. Your own number comes from the estimate.
Often yes, if what's up there is dry and clean but thin. Someone who knows the trade should look at what you have now and tell you whether more is needed and what type makes sense. When I'm up there, I measure how many inches you already have and check whether it's in good enough shape to build on.
Leave it alone and have it tested by an approved lab before anyone disturbs it, because vermiculite may contain asbestos. It's lightweight and flaky, usually gray, and looks nothing like fiberglass. We don't touch it until the results are back, so if you've spotted some, tell us when you call.
For loose fill and air sealing you usually don't, though it's easier on everyone if kids and pets stay clear of the work area. Spray foam is different, because it comes with a re-entry time, the hours before you can come back inside, and I'll go over that for your job at the estimate.
Clear a path to the attic hatch or crawl space door and move whatever's stored right under it, since that's where we'll be coming and going all day. If the hatch is in the garage, give that corner some room too. Beyond that, our crew handles the prep.
Most of the waiting usually happens before our crew shows up, not up in the attic. Old wiring, damp spots or vermiculite results have to be sorted first, and a permit, when one's needed, adds its own wait. Once that's clear, I'll lay out the work days for your house, in the order that makes sense.
Call (707) 576-6028 or send the form, and if you tell us roughly how old your house is, I'll have a good idea what's up there before I climb in.
