Homes across Sun Valley and its edges
Sun Valley sits in its own valley, with Sparks on the east and Reno on the west, and since we're an insulation contractor based in Reno, NV, it's close to home for us. Most of the houses we get into here are single-story, a lot of them older, with attics that got a few inches of insulation long ago and crawl spaces nobody has looked at in years. There's also a fair number of manufactured homes, and each one has its own way of letting the cold in.
We do the same work up in Cold Springs. The price mostly comes down to how much old material has to come out and how many gaps need sealing before anything new goes in. The schedule turns on whether the job needs a permit, and the written estimate I send after my visit has your number. Here, the job usually comes down to an attic that leaks warm air out the top and a floor that lets cold up from the crawl space.
Our services in Sun Valley, NV
A lot of attics here leak warm air through gaps around can lights, plumbing pipes and the hatch, and that's often why one room never feels right. We do the air sealing first, closing those gaps with foam and caulk, so the insulation on top isn't fighting a draft.
Older attics in Sun Valley often have a few inches that have settled flat, deep in the middle and thin at the edges, which is backward. We top them up with blown-in insulation, loose fill blown through a hose, built up evenly to the eaves with the vents kept clear so the attic can still breathe.
When old insulation has been soaked by a roof leak or packed with rodent droppings, new material on top just buries the problem. We vacuum it out and clean the attic before we insulate, and if the roof needs fixing first, I'll tell you the job should wait.
Houses here that sit over a crawl space are where we hear about cold floors, usually because the insulation under the floor has sagged or fallen out. We put it back snug against the floor and seal around the pipes and ducts so the floor stops pulling heat out of the room.
Bare dirt in a crawl space gives off moisture that works its way into the floor framing and the insulation. We lay a vapor barrier, a heavy plastic sheet over the ground, and tape its seams so the space under your house stays drier.
Loose fill can't stop air moving in the room over the garage or in an attic where the ductwork runs. That's where we spray closed-cell foam, a dense foam that blocks air and moisture as it insulates, because there it's worth the higher cost.

What happens when you call us in Sun Valley
Call or send a message
Call (775) 447-1048 or use the form and tell us what's going on, like a cold room or a power bill that jumped. We get back to you and set a time for me to come out to your house.
I look at the house myself
I get into the attic, walls or crawl space, check how many inches are already there and what's under them, and walk you through what I found and what I'd do first, so it helps if you're home. Then I send a written estimate, so you see the cost before anything starts.
We settle the permit question
Once you say yes, I check which office covers your address and whether the job needs a permit, and if it does, we apply for it. We book the install day once that's sorted out.
We install and walk it through
The crew and I do the work together and clean up as we go. At the end I go over it with you, up in the attic if you like, so you know what's there and why the house should feel different.
Sun Valley insulation questions
Do I need a permit to insulate my attic in Sun Valley, NV?
You need one unless the work is on Washoe County's exempt list, because the county issues building permits in Sun Valley for any project that isn't on that list in Washoe County Code, Chapter 100. Before we start, I check your job against the county's list of what requires a permit, and if it needs one, we apply for it.
Who can get a building permit for insulation work in Sun Valley?
You can as the homeowner, or a licensed contractor can, and nobody else. Washoe County gives owner/builder permits only to the homeowner, and every other residential permit goes to a licensed contractor, so when we do the job and it needs one, we're the ones who apply.
Does an insulation contractor need a Nevada license to work in Sun Valley?
Yes, the Nevada State Contractors Board requires anyone who builds or alters a building in Nevada to hold its license, and to have it before they even bid. A repair under $1,000 in labor and materials can be exempt, but not when it needs a building permit, when it's heating or air-conditioning work, or when it's part of a larger project of $500 or more. Washoe County also requires its own business license from any business that comes into the unincorporated county to work, and Sun Valley is one of those unincorporated communities. We're fully licensed and insured.
How much does it cost to insulate an attic in Sun Valley?
The price is set by what's in your attic, so your real number comes in the written estimate I send after I've looked. The big drivers are how many inches are already up there, whether old material that's wet or full of droppings has to come out first, how many gaps need sealing, and whether we're topping up loose fill or spraying foam, which costs more. Sealing the gaps and topping up usually gets you the most for the money unless your ductwork runs through the attic.
What causes cold floors in Sun Valley homes?
Usually it's the crawl space, where cold air under the house pulls heat out through a floor with thin or fallen insulation and open gaps around pipes. Washoe County's building design rules plan for a 17°F winter day and frost reaching 24 inches into the ground, so the space under your floor gets truly cold. I'll check the crawl space on my visit and tell you whether sealing, insulation or a vapor barrier comes first.
How long does attic insulation take, and when can we go back inside?
With blown-in insulation you can usually stay home, and how long we're up there turns on the attic's size, how easy it is to get into and whether old material comes out first. Spray foam is different, because you, the kids and the pets stay out until the foam maker's re-entry time is up, which is how long it says to wait before anyone comes back inside. I'll tell you which applies to your house before we book the day.
