Drafty rooms and an upstairs that never feels right usually trace back to the attic. Open-cell foam seals the leaks while it insulates.
Open-cell foam insulation in Visalia is soft spray foam we put under the roof deck or into open walls. It expands to fill the gaps, so it slows heat and stops air leaks at the same time, and when it goes under the roof it turns the attic into a sealed space.
Most people call because the room over the garage or a bedroom upstairs won't stay comfortable, or the power bill keeps climbing, and the attic is usually where that starts. Foam costs more than blown-in insulation, loose fill we blow through a hose, so if your ductwork isn't up in the attic I'll usually tell you that sealing the gaps and topping up the loose fill is the better buy.
The price moves with how much roof deck or wall gets sprayed, how many inches go on, and whether old insulation has to come out first. The schedule turns on clearing what's stored up there, whether a furnace or water heater in the attic needs another trade before we spray, whether a permit is needed, and when your household can be away from home. Your estimate puts your own figure in writing.
Nothing gets priced until I've seen the attic, because what's already up there decides what has to happen before any foam goes on.
I come out myself, get up into the attic or down into the crawl space, and take photos and notes on the old insulation, wiring, gas appliances and anything stored up there. I started this business in 2023 to do this kind of careful work in lived-in homes.
The estimate lists each step in the order we'll do it, so you can see why old insulation comes out before foam goes in. I go over the photos with you, so you're looking at your own attic and not just taking my word for it.
On the day, our crew protects the house and works through the estimate in that order. We're licensed and insured, and I check the finished work against the estimate before we pack up.
We start by clearing a path and covering what's below, then pull out any old insulation that's soaked or full of droppings, because foam sprayed over it only hides the problem. Open-cell lets water vapor through, so before we spray under the roof we plan how moisture will leave the attic, and we look at any fuel-burning appliance up there and tell you if another trade needs to change it first. Then we spray to an even depth all the way out to the eaves and corners, since the edges are where coverage usually runs thin.
Foam in the attic is one piece of the building. If you manage a shop, office or rental, our commercial insulation work plans the foam around whatever else is going on in the building. And if damp is coming up from the dirt under your floor, a crawl space vapor barrier handles that, because attic foam won't.
The order matters more than the foam itself, so we keep the work in this sequence.
We move stored boxes out of the way and cover floors and furniture along our path, because spray foam sticks to whatever it lands on. Your household heads out before we start spraying.
Wet or dirty insulation comes out, and any appliance change another trade has to make gets done before we spray. If something isn't ready, I'd rather move the date than spray over it.
Our installers spray the roof deck or walls in passes so the foam builds up to the depth on your estimate. We watch the edges and the area around the hatch most closely, because that's where it's easiest to come up short.
We trim any foam that sticks out, bag the waste and let the house air out through the re-entry time, the wait before you can come back inside. We'll tell you when that's up.
Fill out the form or call (559) 409-1169, and we'll reply within one business day to set a time for me to come out. The estimate is free, done on site and in writing, and there's no obligation to book the work.
(559) 409-1169Open-cell foam has an R-value, how well insulation slows heat, of about 3.6 per inch, while typical closed-cell foam runs about R-6 per inch, so open-cell needs more thickness to do the same job. Closed-cell foam is a denser foam that also blocks moisture. When both could work in your attic, we'll price both so you can compare.
Yes, because federal guidance says open-cell foam lets water vapor pass through, so it can't be the layer that controls moisture, and an attic sealed with foam under the roof needs a way to remove it. The same guidance says any fuel-burning appliance in a sealed attic should be a direct-vent, sealed-combustion unit that vents outdoors. We settle both before the foam goes on, not after.
Plan on everyone staying out for at least 24 hours, since federal safety guidance advises residents leave the home for at least that long. Line up a place for the family and pets before the job is booked so the date doesn't slip. EPA guidance notes spray foam chemicals can cause asthma, other breathing trouble and skin or eye irritation, so if someone at home already has breathing problems, tell me and ask how our crew limits exposure.
The City of Visalia issues permits only to property owners or state-licensed contractors. California licenses insulation contractors under a class from the state contractors license board that covers installing any insulation for heat or sound control, so that's the license to ask any contractor about.
Before work starts, we check with the city or county office that covers your address, and when a permit is needed, we apply for it as your licensed contractor and meet the inspector on site. Visalia also keeps a handout of mandatory requirements for insulation and roofing projects on its forms and handouts page, and it's worth going over with us while we plan. Whether your foam needs a covering such as a coating or drywall depends on the foam and the code, and that's part of what we check.
We're based in Visalia and work across the cities around it, from Kingsburg and Selma to Hanford, Lemoore and Woodlake. A lot of the houses we see have the ductwork and furnace up in the attic, which is when open-cell foam starts to make sense. If your city isn't named on the site, call and ask.
Call (559) 409-1169 or send the form, and if you know whether a furnace or water heater sits in the attic, mention it so I can plan the visit around it.
If you're not sure foam is the right fit for your attic, call and let me take a look first.
