Carson City houses, as we see them on the job
Carson City is a short drive down from Sparks, and the calls we get there sound a lot like the ones at home. People tell us about a room over the garage that's never comfortable, a hallway that's drafty no matter where the thermostat sits, or a power bill that keeps creeping up. We see older single-story houses with low attics and crawl spaces, newer two-story homes with ductwork running through the attic, and a fair number of rentals where the owner wants the problem fixed once.
We see the same mix south in Indian Hills and north toward Reno. The age of the house shapes the job more than anything, because an older attic has usually been topped up a time or two, and what's under the newest layer matters more than what goes on top.
What a Carson City job involves, from permit to price
In Carson City, permits go through the city's Building Division. It issues permits to build, alter or repair a building and to install or replace regulated electrical, gas, mechanical or plumbing systems. A permit has to be in hand before work starts, so when your job needs one, that step sets our start date. Before we begin, we check with the Building Division, tell you what it asks for and take care of the permit when your job needs one. We're fully licensed and insured.
I do every estimate myself, so I'm the one driving down from Sparks, the same as I do for jobs out in Fernley. The price moves mostly with what's already in your attic or crawl space and whether it has to come out first. The schedule moves with the permit step and with anything I ask you to fix before we insulate. You get your own figure at the estimate.
Why Carson City houses end up needing us
In the older houses, the attic has usually been topped up already, and the trouble is often underneath. If the old layer got soaked or is full of droppings, new material on top just buries the problem, so we take the old layer out first. We also find eave vents buried under loose fill, and coverage piled deep in the middle and thin at the edges, which is backward. We clear those vents so the attic can breathe, and we make sure the edges get their share.
Cold floors usually point down to a crawl space with little or nothing under the floor. Our crawl space insulation work starts with closing the gaps around pipes and wires, because insulation can't keep a floor warm while air is pouring past it.

I come out and look
I do the estimate myself, up in the attic and down in the crawl space, checking how many inches are already there and what shape they're in. I also look at your gas appliances and fresh air, because a house has to stay safe once we tighten it up.
Go over what I found
I show you what's there and what should be fixed first, even when that's a roof leak or old wiring and not insulation. Whatever you decide, you'll know your house a little better than you did.
Sort out permit and prep
If you go ahead, we sort out any permit the job needs with the Building Division before work starts. You clear a path to the attic hatch or crawl space door, and we cover floors and set up from there.
Install and walk the job
Our small crew does the install and I'm on the job with them, sealing the gaps around lights, pipes and the hatch before any insulation goes in. Before we pack up, I walk the finished job with you so you know what's up there now.

Carson City insulation questions we hear
Do I need a permit to add insulation to my house in Carson City?
Ask the Building Division before work starts, because the city's list of work that needs no permit doesn't say either way about insulation. That list, from an older version of the city's building rules, covers things like small sheds, low fences and decks, and finish work such as painting and carpet. The Building Division has the current list, and we check for your address before we start.
Does moving ductwork or fixing wiring during an insulation job need a permit in Carson City?
Yes. Under the city's older rules, installing, altering or replacing regulated electrical, gas, mechanical or plumbing systems is permit work through the Building Division. The owner, or someone the owner authorizes, applies to the building official, who runs the Building Division, and gets the permit before work starts. If I find old wiring that should be fixed first, I'll tell you, so it gets sorted out before we insulate over it.
How much does insulation cost for a Carson City home?
There's no honest number until I've seen the space, because the price depends on what's already in your attic or crawl space and what has to happen before anything new goes in. The biggest factors are the inches already up there, whether soaked or dirty old material has to come out, how many gaps need sealing, how easy the space is to reach, and whether foam makes sense instead of loose fill. I'll give you your own figure at the estimate and tell you if part of the job isn't worth paying for.
How long does attic insulation take, and do we have to leave the house?
With blown-in insulation, which is loose fill blown through a hose, you can usually stay home while we work. How long we're in your attic depends mostly on how much cleanup and sealing come first. Spray foam is different. You, the kids and the pets stay out until the re-entry time, which is the wait the foam maker sets before anyone goes back inside.
What causes a hot room over the garage or cold floors in an older Carson City house?
Usually it's air leaking through gaps more than missing insulation. The common spots are around can lights, pipes and the attic hatch, and the floor over a bare crawl space. That's why we do air sealing, which means closing those gaps, before any insulation goes in. Otherwise the new insulation spends its life fighting a draft.
What is the best way to insulate an older Carson City attic, spray foam or blown-in?
For most attics, sealing the gaps and topping up with blown-in is the better buy, unless your ductwork runs through the attic. Foam costs more because it seals air while it insulates, so it earns that price around ducts and in tight spots. Closed-cell foam, a dense foam that blocks moisture, can also make sense in some crawl spaces, and I'll tell you at the estimate if yours is one of them.
