Crawl space insulation in Sun Valley NV - warmer floors over a dry crawl space

Cold floors and a climbing power bill usually start under your feet. We seal and insulate the crawl space so the floor holds heat.

A crawl space has a white ground vapor barrier, insulated walls, exposed floor joists, and a large silver duct.

I write your estimate myself

I'm usually the one who comes out to look at the crawl space and write the estimate. Our install crew does the work with a lead installer on site, so one person is in charge under your house.

In Sun Valley since 2023

I started this company in Sun Valley in 2023 after learning insulation on job sites beside experienced installers. I ran a small business before that, so I'd rather tell you a job isn't worth doing than sell you one.

Licensed and fully insured, every job

We're licensed and fully insured, which matters when a crew is working under your floor. When you want someone to look at your crawl space, call (775) 447-1132 or use the form below.

Crawl space insulation in Sun Valley

Crawl space insulation in Sun Valley, NV means sealing the gaps where outside air gets under your house, then insulating either the crawl space walls or the floor above, which cuts heat loss through the floor. It's for homeowners with cold floors or drafty rooms.

Most calls start with a cold floor, a room over the crawl space that never warms up, or a power bill that keeps climbing. Down there we usually find a vented space with thin or sagging insulation and open gaps around pipes and wires. If the old material got soaked or filled with droppings, it comes out before anything new goes in, because laying fresh insulation over it just keeps the problem.

Price comes down to the size of the space, whether we insulate the walls or the floor, how much old material has to come out, and whether the crawl space is being sealed, since that adds planning for drying and any equipment down there. Tight access takes longer. The schedule usually turns on what has to happen first, like mold cleanup. My written estimate shows what I'd do first and what can wait.

Crawl space insulation, sealing and the work around it

Walls or floor, decided together

Before anything gets priced, we talk through whether the crawl space walls or the floor above should carry the insulation in your home. When ducts or a furnace sit down there, sealing and insulating the walls with rigid foam can give them an insulated, air-sealed space. Some foam can give off toxic or flammable gases when heated, so most codes want a gypsum board cover over it, and it's fair to ask whether the foam we pick meets local code. If the rooms above have thin walls too, I'll tell you whether wall insulation belongs now or later.

Sealing it safely and keeping it dry

If your crawl space is going to be sealed, closing the vents is only the start. Closed vents alone can raise moisture, and if a furnace or water heater down there vents naturally, closing them can turn deadly, so we settle how that equipment will be handled before any sealing begins. A sealed space still needs a way to dry, and federal guidance counts a small feed of heated or cooled air from your home's system among the most effective, which pulls your heating setup into the plan. Gaps around pipes and wires get the same work as our air sealing services.

  3. Install, cleanup and walkthrough

    Our crew does the work, then cleans up the crawl space and any path through the house. We walk through the finished job together, so you see what went in and where before we call it done.

Crawl space questions from Sun Valley homeowners

Should I insulate my crawl space walls or the floor above?

Federal guidance favors the walls, calling air sealing and insulating along the crawl space walls a best practice in all climates. In some homes the floor above makes more sense as the insulated layer. Ask any installer which layer suits your house before you compare quotes, and I'll give you my answer at the estimate.

Does mold in my crawl space need fixing before insulation?

Yes. Surface mold in a crawl space calls for a certified mold remediation expert, who inspects the space and sets a cleanup plan before insulation goes ahead. Tell us about any mold you've seen when you reach out, so we plan around that cleanup instead of insulating over it.

Do I need a radon test before sealing my crawl space?

Yes, the EPA and the Surgeon General recommend testing every home for radon, a gas that comes up from the soil. Where radon is a risk, a home with a sealed crawl space needs testing and ongoing monitoring, plus an approved system to lower it if the levels call for one.

How much does crawl space insulation cost in the Reno area?

Insulating a crawl space in the Reno area usually costs about $1,500 to $7,000 per job. That's the going range for the work around here, not a quote from us. After I look at your crawl space, you get your own number in a written estimate.
