Houses and small buildings across Reno
Reno is home for us, and most of our calls come from here. The houses run the full range. Some are older homes with a few inches of tired insulation and an attic hatch nobody has opened in years. Others are newer houses where the builder put in the minimum and the room over the garage has never felt like the rest of the house. We work across Sparks and up into Sun Valley too, and the attics and crawl spaces there look a lot like Reno's.
That range is why I look before I quote. An older house usually needs the old material checked and the gaps sealed before anything new goes in, while a newer one more often needs thin edges and the garage room brought up to match.
Our services in Reno, NV
A lot of Reno attics we open have insulation that's deep in the middle and thin at the edges, which is backward. We even out the coverage and bring the edges up without burying the eave vents, so the attic can still breathe.
When upstairs runs hot or a hallway feels drafty, the cause is usually open gaps around can lights, pipes and the attic hatch. We seal those first, because insulation laid over a draft just keeps losing to it.
In older houses the old material is sometimes soaked from a past roof leak or full of droppings, and new insulation on top only hides the problem. We pull it out and clean up before anything new goes in, and if the roof still leaks, I'll tell you to fix that first.
Where ductwork runs through the attic or the room over the garage won't hold heat, spray foam insulation seals air and insulates in one pass. It costs more than loose fill, so I only suggest it where that sealing is worth paying for.
Cold floors over a crawl space usually mean the insulation underneath has sagged, fallen down or was never put in. We check the crawl space for moisture first, then insulate so the floor above stops pulling in the cold.
For most Reno attics without ducts up there, sealing the gaps and topping up with blown-in insulation, loose fill we send through a hose, is the better value. We blow it to an even depth across the whole attic, edges included, and keep the vents clear.

What happens after you call us in Reno
Call or send us a message
Tell us what's bugging you, like the hot upstairs bedroom or the drafty hall, and we'll get back to you to set a time. Plan to be home for the visit so you can show me the rooms that bother you.
I come out and look
I check the attic, walls or crawl space myself, see how many inches are already up there and walk you through what I found and what I'd do first. Then I send a written estimate, so you see the price before you decide anything.
We settle permits, then install
Once you say yes, we sort out the permit question with the office that covers your address, then the crew and I do the work, sealing gaps before any insulation goes in. If we're spraying foam, I'll tell you ahead of time when you need to be out and when you can come back.
We walk through it together
When we're done, I go over the work with you and show you what changed, including the sealed gaps you won't see once they're covered. We clean up before we leave.
Reno insulation questions answered
Does insulating my attic in Reno need a permit?
Most construction projects in Reno need a building permit from the city's Development Services Department, and the building code lists some work that's exempt. I won't guess whether your job is on that list. Before work starts, we confirm which office covers your address and apply for the permit when the job needs one.
How do I find out if my house is under the City of Reno or Washoe County?
Check whether the property sits inside Reno city limits or in unincorporated Washoe County, because that decides which office handles your permit. Washoe County covers properties outside the Reno and Sparks city limits, and some addresses fall in what the county calls a city's sphere of influence, so Washoe County's getting-started page asks you to sort that out first. If you'd rather not dig into it, we'll work it out when I come out.
How long does a Reno building permit stay valid?
A Reno permit stays valid only if it records a Pass or Partial inspection within the first 180 days, and again in every 180 days after that. A permit with no such inspection expires, so we keep an eye on inspection timing while the job is underway.
What happens if insulation work was done in Reno without a permit?
If the work needed a permit and didn't have one, the city adds compliance fees on top of the regular permit fees when that permit is taken out. That's why we settle the permit question before the crew starts, not after.
What affects the cost of attic insulation in Reno?
The price comes down to the size of the attic, how much insulation is already up there and whether old material has to come out first. Foam costs more than loose fill, and sealing gaps around lights, pipes and the hatch adds time but usually does more for comfort than extra depth. You get your own number in the written estimate after I've seen the house.
How long does attic insulation take, and when can my kids and pets come back?
Timing turns mostly on prep, since sealing gaps and pulling out old insulation take longer than laying new fill. With blown-in work you can usually stay home. With spray foam you'll need to be out for a while, and I'll give you the re-entry time, how long before it's safe to come back in, before we start.
