Spray foam we install in Kennewick homes
Open-cell spray foam
A softer, lighter foam that expands to fill cavities and stop air leaks. It suits attic rooflines and walls where drafts are the main complaint.
Closed-cell spray foam
A dense, rigid foam that blocks air and moisture in a thinner layer. It suits crawl spaces and rim joists, the boards along the top of the foundation, where damp is the worry.
Is spray foam insulation worth it for a Kennewick home?
Spray foam insulation in Kennewick is foam sprayed into walls, attics and roofs, where it insulates and blocks air leaks in the same layer, so less heat slips out of drafty rooms through the gaps.
Most calls start with a cold floor, a hot upstairs or a power bill that keeps climbing, and foam is often the first fix people have heard of. The price moves with how much area we're covering, how thick the foam goes, which type fits and whether old material has to come out first, and the schedule turns on that prep plus the time your household needs away from the house. Your written estimate spells out what we'd do and why, and if foam isn't the best fit, it'll say so plainly and point you to air sealing or another option.
Spray foam, sealing and the prep around it
Before I recommend foam, I look at the space and ask who lives in the house and whether anyone has health concerns, because foam isn't the right fit for every home or household.
Deciding foam or loose fill
Foam seals and insulates but costs more, so unless ductwork runs through the attic, sealing gaps and adding blown-in insulation usually wins.
Clearing out bad material
Before foam goes up, we pull out old attic insulation that's soaked or full of droppings, because covering it leaves the problem in place.
Getting the house ready
Before spraying, we walk you through the prep, like covering surfaces, ventilating and putting out gas pilot lights, and help plan your time away.
Spraying out to the edges
Our installers work the foam into the far corners and around pipes and the attic hatch, because that's where coverage usually runs thin.

Spray foam questions from Kennewick homeowners
How much does spray foam insulation cost in Kennewick?
Spray foam covering 1,000 square feet with 3 inches of foam in Kennewick usually costs about $1,600 to $4,100 per job. Open-cell foam sits toward the lower end of that range and closed-cell toward the upper end. Your own figure comes from the written estimate after I've seen the space.
How do I choose between open-cell and closed-cell foam for my walls?
In a frame wall, the difference that matters most is drying. Open-cell foam blocks air but lets water vapor through, while closed-cell foam at typical thicknesses slows vapor, so a frame wall sprayed with it won't dry well to the outside. We look at your walls and weigh that before recommending either one.
How long do we have to stay out of the house after spray foam?
Staff at the Consumer Product Safety Commission advise leaving the home during installation and for at least 24 hours after. When you can actually come back depends on the foam formula, how much goes in, temperature, humidity and ventilation. We help you plan where to stay before work starts.
Is spray foam safe if someone in my family has asthma or allergies?
Households with asthma or allergies should weigh that before choosing foam. The same federal staff advise people with skin conditions, respiratory allergies, asthma or a past sensitivity to isocyanates, a chemical used to make the foam, to read the product information closely and consider other insulation if needed. We ask about this at the first visit.
Can I install spray foam insulation in my attic myself?
The industry's homeowner guide says mid-size and larger jobs, such as walls, attics and roofs, are for a trained spray foam contractor or weatherization pro. Those are the areas we spray, with our own installers doing the work.
How long does spray foam insulation last?
Spray foam resists breaking down and settling over time, according to the industry's homeowner guide, so it doesn't slump the way loose fill can. For the expected lifespan of a specific foam, the guide says to ask the contractor or the product maker, so ask us at the estimate and we'll share what the maker says about the foam we'd use.
Other work that pairs with foam
Attic insulation
If the upstairs stays hot all summer or the attic has only a few inches left, attic insulation work may be the simpler fix than foam.

Loose fill blown through a hose levels out thin spots and adds depth across an attic floor that's already sealed, usually for less than foam.

Gaps around pipes, wires and the attic hatch let warm air escape no matter what sits on top, so closing them first often matters most.

Spray foam insulation permits and checks in Kennewick
The City of Kennewick requires a residential building permit for new homes, remodels, additions and miscellaneous projects, and its list doesn't name spray foam, so it doesn't settle whether your job needs one. The city's Building Safety Division handles plan review and inspections and interprets the building codes, so that's where we ask before work starts, and when a permit is needed, we take care of it with them. Before you hire anyone, you can look up a business's contractor registration and whether its workers' comp account covers its employees on the state's Verify tool.
Many attics we open around here have ductwork running through them, which is the case where foam usually earns its place. We do the same work in Pasco and Hermiston, and we check with each city or county building office there too, since the rules differ.
