A drafty vaulted ceiling, a cold room over the garage or a clammy basement wall? Closed-cell foam insulates and seals in one firm layer.
Closed-cell foam insulation is a dense spray foam that hardens into a rigid layer, and in Carson City homes we use it where a roof slope, a room over the garage or a basement wall needs to stop drafts and damp in very little space.
If you're looking into it, you've probably got a room that never feels right. Maybe it's a vaulted ceiling with shallow rafters, a cold floor over the garage or a basement wall that feels damp to the touch. Those are the spots where regular insulation either won't fit deep enough or doesn't hold up when it gets wet, and that's where closed cell earns a look.
The price mostly comes down to how many square feet we're covering, how thick the foam has to go and how easy the space is to get into, plus any old insulation that has to come out first. The schedule turns on that same size and access, and on the stretch of time you'll spend out of the house while the foam cures. You'll get your own number and a plan for that day from the estimate.
Most of the time it's me calling you back, and from there it goes in three steps. Call (775) 227-5588 or use our request form to get started.
I started this business in 2017 after years behind a desk, and I still do every estimate visit myself, flashlight in hand, in the attic, crawl space or basement with you. Then I put together an estimate and go over what I found before you decide anything.
We're fully licensed and insured. Our installers do the spraying, and a lead installer runs each job so you know who's in charge on your install day.
We clean up after ourselves, and then I walk you through the finished job so you know exactly what's up there and why. Your satisfaction, guaranteed.
Closed cell costs more, so I only suggest it where it earns the extra money, like a tight roof slope or a wall that tends to get damp. If air sealing, closing the gaps where air leaks in, plus a top-up of blown-in loose fill will do the job, I'll tell you that instead, unless your ductwork runs through the attic and needs that space sealed around it. Where foam is the right call, we clear out anything soaked or full of droppings first so we're not burying the problem, then spray an even layer that seals the gaps around pipes, wires and the hatch as it goes.
Not every part of a house needs the dense stuff. Where there's room for thickness and moisture isn't a worry, open-cell foam insulation usually costs less and does the job. We also spray closed cell in shops, offices and rentals through our commercial insulation work.
We work in this order on purpose, because foam that goes on before the space is ready is hard to fix later.
We move what's stored there, pull any bad insulation and mask off everything nearby, because foam sticks to whatever it touches. You'll know the re-entry time, the point when it's okay to come home, before we start.
Our lead installer works through the space bay by bay so the foam fills each cavity and bonds to the framing. That bond is what stops the drafts, so we take our time at corners and around anything that pokes through.
The foam needs time to cure and air out while nobody's home. We keep the work area set up for that and don't rush it.
Once the foam is firm, we trim anything that sticks out past the framing. Then we check the edges and corners for thin spots, since that's where coverage tends to come up short.
Send the form with the areas you'd like insulated and a rough square footage, and we'll get back to you within one business day to set up a free visit at your house. I'll look the place over with you and put together an estimate, with no obligation to go ahead. You can also call (775) 227-5588.
(775) 227-5588Closed-cell spray foam in the Reno area usually runs about $1 to $1.50 per board foot, which is one square foot of foam an inch thick. Your total depends on how much area we cover and how deep it goes. I'll measure all of that on the estimate visit.
It's better where you need a rigid, water-resistant layer in a tight space, like a cathedral ceiling or an unvented attic, and open cell is often the better buy everywhere else. Closed cell is rated at R-6 per inch, R-value being how well insulation slows heat, and at its usual thickness it blocks moisture vapor and won't soak up water. It costs more mainly because there's more material packed into the same space, and that's also what makes it hard and tough to compress.
Yes, and it's one of the best places for it, because research on basements found the most consistently effective setup puts a water-tolerant insulation right against the inside of the foundation wall. On the rim joist, the band of wood sitting on top of the foundation, spray foam stops drafts and insulates in one step. Closed cell does that with a thinner layer than open cell needs.
Plan on at least 24 hours away, because federal consumer safety staff advise homeowners to leave during installation and for at least a day after. Line up a place to stay for the kids and pets, and we'll go over the safety steps with you before the crew starts. If anyone at home has asthma, respiratory allergies, a skin condition or a past reaction to spray foam chemicals, the same staff suggest reading the product information first, and another insulation may suit your house better.
In Carson City, permits go through the Carson City Building Division, and its online portal covers work that alters an existing house, which is where most foam jobs land. The city only takes an application signed by the property owner, an authorized agent or a licensed contractor, so if your job needs one, we take care of the paperwork for you. Nevada brings in newer energy codes on a set cycle, and local governments can add stricter rules of their own, which is one more reason we check before we start.
We're based in Carson City and work across the cities around it, from Reno and Sparks down to Gardnerville and up to Incline Village, plus plenty of places in between. The rules differ between Carson City, the counties and those cities, so we check with the office that covers your address. Out here we see a lot of vaulted ceilings, rooms over garages and older basements, and those are the spots where closed cell usually earns its keep.
Have the areas you want insulated and a rough square footage handy, and think about when you could be away for a day, so we can plan the install around your schedule.
If you're not sure closed cell is right for your house, call (775) 227-5588 and I'll tell you straight.
