Closed-cell foam insulation in Jerome ID - tight spots sealed and insulated
Cold floors or a drafty basement? We spray dense foam into the rim joists and tight spots so they seal and insulate in one pass.
Where closed-cell foam earns its pricein Jerome homes and shops
Most calls about closed-cell foam insulation in Jerome start with cold floors, a drafty basement or a room over the garage that never warms up. Closed-cell is a dense, rigid foam that won't soak up water, and national guidance rates the typical product at about R-6 per inch, R-value being how well insulation slows heat.
That's why we like it for rim joists, the framing where your floor sits on the foundation, and for tight spots where every inch has to work hard. It costs more, so in an open attic I'll usually tell you that sealing the gaps and topping up the loose fill is the better buy, unless your ductwork lives up there.
Price comes down to how much area we cover, how thick we spray it, how hard the space is to reach and whether old insulation has to come out first. The schedule turns on the permit question and a day out of the house while we spray. Your estimate is a written plan with photos, with any fixes listed first.
You'll know what's going in, where and why before we spray a thing, so call (208) 544-9045 and I'll come take a look.
Where closed-cell foam goes in a building
Closed-cell goes where space is tight or moisture is around, so we set the thickness for each spot and point you to other insulation where foam isn't worth it.
Rim joists
Foam seals the air leaks along the rim and insulates it in the same pass, which is hard to manage with batts cut to fit around wires and pipes.
Crawl space and basement walls
On concrete that stays damp, a foam that won't take on water makes sense, and it helps the cold floors above. We look for leaks before we spray.
Frame walls
Foam fills open stud bays and seals around boxes and wires as it goes, but it changes how a wall dries, so walls get a moisture talk first.
Shops and metal buildings
Closed-cell sticks to steel and stays rigid against bumps, so it suits shops and pole barns. Our commercial insulation work covers the larger buildings.
Why Jerome homeowners choose usfor foam, attics and crawl spaces
Expect plenty of explaining up front, a plan you can read for yourself and then our own installers doing the work, with a little dry humor if the crawl space allows.
The owner writes your estimate
I come out myself to look at the space, answer your questions and write the estimate, so the person explaining the plan is the one who stands behind it.
Fixes go ahead of the foam
Foam over a roof leak, a wet sill or bad wiring just hides the problem, so anything that needs fixing sits at the top of your plan.
Licensed and insured for your job
We're licensed and insured, and you're welcome to ask to see both before anyone steps into your crawl space.
Back in the trade since 2021
I ran insulation jobs when I was younger, left for years and came back in 2021 because I missed the work, and we've been at it five years since.
Enough know-how to judge us

First call to final walkthroughin the order that matters
We keep it simple. You get one visit, one written plan with photos and the fixes listed first, so you can see the order of the work before you decide.
You call or write
Call (208) 544-9045 or send a note through the form with the spaces you have in mind, and we'll set up a time for me to come out.
I look at it with you
We go through the attic, walls, basement or crawl space together while I take photos, then I write a plan with anything that needs fixing at the top.
Permit and spray day
Once you say yes, we sort out the permit question with the right office and pick a spray day, so you can plan your day away from the house.
Fixes, then foam
The fixes on the list come first, then our installers spray to the planned thickness. Under a county permit, the insulation inspection needs 24 hours' notice, so we book it ahead.
Cleanup and walkthrough
We clean up, and I check the work and walk the finished job with you, pointing out what went where so it all makes sense to you.
Closed-cell foam questions
How much does closed-cell spray foam insulation cost in Jerome, ID?
Closed-cell spray foam in Twin Falls usually costs about $1 to $1.40 per board foot, which is one square foot of foam an inch thick. That's the going rate in the area, not our quote, and your total comes from the area, the thickness and how hard the spaces are to reach. I'll measure and write it all up when I come out.
How long does it take before we can go back inside after spray foam?
Everyone in the home, kids and pets included, should be out while the foam is sprayed, and some manufacturers recommend waiting 24 hours after application before coming back. That re-entry time, when it's safe to return, can vary by product, so ask the maker or supplier for its ventilation and re-occupancy times, and we'll tell you which product we're using.
What is the best way to insulate rim joists, closed-cell or open-cell foam?
Closed-cell usually wins on rim joists because national guidance counts it as an air barrier at a finished 1.5 inches, while open-cell needs 5.5 inches to do the same job. In a shallow rim bay that difference matters. Open-cell foam insulation has its place in roomier spaces, and I'll tell you which fits where.
Do I need a permit for spray foam insulation in Jerome, ID?
It can, depending on which office covers your property, and we check before anything starts. The city's Building Safety Department issues residential permits in Jerome, and its list names houses, additions, remodels and decks but not foam insulation, so your job is worth asking about. Jerome County requires a permit before any construction begins, may charge double fees when work starts first and lists insulation among its inspections. If your job needs a permit, we handle the application and set up the inspections.
What paperwork should an Idaho contractor give me before I sign?
Idaho Code requires a general contractor to give you a disclosure statement before a contract over $2,000 to alter or repair a home. If your foam job is that size, ask for the statement and read it before you sign.
Is closed-cell foam a vapor barrier, and can it go in my walls?
At typical thickness, closed-cell foam acts as a vapor retarder and lets almost no moisture vapor through, so a frame wall filled with it won't be able to dry well to the outside. That doesn't rule it out, but before we recommend it for walls, we talk through how your wall will handle moisture once the foam is in.
