Open-cell foam insulation in Kennewick, WA - an attic sealed tight over a sound roof

Hot rooms upstairs and drafts from the attic usually mean air is slipping through. Foam sprayed in place closes those paths and slows the heat.

Where we spray open-cell foam

  • Under the roof deck

    We spray the underside of the roof so the attic becomes part of the heated house, which suits homes with ductwork or a furnace in the attic.

  • Open walls and ceilings

    When a remodel has walls or ceilings open, the foam fills around wires and pipes, stops drafts at every gap and cuts down sound between rooms.

Is open-cell spray foam a good fit for my Kennewick home?

Open-cell foam insulation in Kennewick, WA is a soft spray foam we apply under the roof deck or into open walls, where it seals air leaks and insulates in one layer. Each inch rates about R-3.6 on the R-value scale, which measures how well insulation slows heat.

Most calls about foam start with a room over the garage that won't hold heat, an upstairs that's hot all summer or a power bill that keeps climbing. Open-cell is one of the two kinds of spray foam insulation we install, and what you pay for it depends on how much roof deck or wall we cover, how deep the foam goes, whether old insulation has to come out first and how easy the space is to reach. The schedule turns mostly on the roof, since any leaks get fixed before we spray, and on the time your household spends away while the foam cures. Your estimate lays out what we'd do and why, and it's where your own figure comes from.

Open-cell foam, from roof check to cleanup

Open-cell stops air but lets moisture through, so I only suggest it where your house has another way to handle moisture, and I look at the roof first.

  • Roof checked first

    Before foam goes under the deck, the roof gets inspected and leaks fixed, and an aging roof may be worth replacing first.

  • A plan for moisture

    Since open-cell lets vapor through, we settle how moisture is handled first, whether by a separate vapor layer or a crawl space vapor barrier.

  • Old material out, space masked

    Soaked or droppings-filled insulation comes out and the space is masked off, so the foam bonds to clean wood and lands nowhere it shouldn't.

  • Full depth to the edges

    We fill eaves and far corners as fully as the middle, as on our commercial insulation jobs, since thin edges let drafts in.

Questions about open-cell foam in Kennewick

How much does open-cell spray foam insulation cost in Kennewick?

There's no flat price, because the area, the foam depth and the prep covered above change from house to house. Foam costs more than sealing the gaps and topping up loose fill, and that cheaper route with attic air sealing usually wins unless your ductwork runs through the attic. Your estimate shows your own figure and which way I'd go.

Is open-cell foam a good idea under my roof deck?

It can be, as long as the roof is sound and your house has another way to handle moisture, because open-cell foam won't stop vapor on its own. In cold and mixed climates, shingles and most roofing act as a vapor barrier on the wrong side of the deck, so the type and depth of insulation under it affect whether condensation forms. Closed-cell foam can serve as both the insulation and the vapor control, which is why I sometimes point people that way.

How long do we have to stay out of the house after spray foam insulation?

Everyone should be out while we spray and stay out until the foam has cured and the house has been aired out and cleaned. Some foam makers call for 24 hours before people move back in, but it varies by product, so plan to stay somewhere else and ask us what the product calls for. Anyone with asthma, skin conditions, respiratory allergies or a past reaction to isocyanates, a chemical used to make the foam, should read the product information first and may want a different insulation, and other trades working on the house need to be out too.

What is the best way to turn a vented attic into a conditioned attic?

Close off the vents, insulate under the roof deck and give the attic a way to remove moisture, because a sealed attic no longer dries the way a vented one does. I'll show you on the estimate how moisture will leave your attic before any foam goes up.

How do I check an insulation contractor's license in Washington?

Look the business up on the state Department of Labor & Industries' Verify tool, which shows whether its contractor registration is active and whether it has a paid-up workers' comp account covering its employees. The same search shows safety violations and lawsuits against a contractor's bond. You're welcome to look us up there before you sign.

Does spray foam insulation have to be covered after it's installed?

Some foam does and some doesn't, because whether it needs a coating or drywall over it as a thermal or ignition barrier depends on the product and the code. We check what the foam needs in your space and put any covering on the estimate.

Open-cell foam insulation in Kennewick and nearby cities

Whether insulation work needs a permit isn't the same from one city to the next, so before we start we ask the city or county building office, and when a permit is needed we take care of it with them. In Kennewick, any work that does need a permit gets inspected by the city's Building Safety Division at set stages, so we plan the spraying around those visits. The state energy code also sets minimums for ceiling insulation, and it's fair to ask me how the foam depth we plan compares.

Plenty of houses here have ductwork running through the attic and roofs of every age, so the roof check matters as much as the foam, and we see the same mix on jobs in Richland and Pasco. We're based in Kennewick and work across the cities around it on both sides of the state line.
