Truckee houses, as we see them from the attic
Truckee is a drive up I-80 from our base in Sparks, and it's one of the cities we work in, along with the Reno and Sparks area and places like Indian Hills. The houses here run from older cabins to newer full-time homes, and plenty of them are second homes that sit empty for weeks, so nobody's been up in the attic or under the floor in a long time. The calls sound a lot like the ones we get in the valley, such as cold floors, a drafty bedroom or a heating bill that keeps climbing, but the winters up here push harder on every gap.
The age of the house tells me a lot before I go up the ladder. Older cabins often have thin or patchy insulation in tight, odd-shaped attics, while newer homes usually have more up there but still leak around lights, pipes and the hatch, so a Truckee job is often less about piling on more and more about fixing what's already in place.
Working in Truckee: permits, roads and what moves the price
Truckee is in California, so building permits here come from the Town of Truckee's Building and Safety Division, not the Nevada offices we deal with closer to home. Anything past purely cosmetic work like painting or flooring starts with a call to the division, so before work starts we check with them, tell you what they ask for and take care of the permit when your job needs one, and the start date waits on that answer. The price moves mostly with how big the attic or crawl space is, how much old insulation has to come out first, and whether the house calls for foam or blown-in, which is loose fill blown through a hose, and I'll walk you through all of it when I'm at your house.
Getting to the house is part of the schedule here. We come up I-80 from Sparks, and in winter the road over the pass and a snowed-in driveway decide which days our crew can reach you and park close enough to run a hose, so we plan Truckee work around the weather and let you know early if a storm pushes things back. It's the same small crew, fully licensed and insured, doing the same work we do in Reno, with more snow to work around.
What long winters and empty weeks do to a Truckee house
A long snowy winter finds every gap in a house. Warm air slips up into the attic around can lights, plumbing and the hatch, cold air gets pulled in down low, and you end up with cold floors, a chilly room over the garage and a bill that doesn't fit the size of the place. Laying insulation over those gaps won't stop the draft, so we start with air sealing to close them, then keep the new insulation full out to the edges of the attic, where it's usually thinnest, and clear of the eave vents so the attic can still breathe.
A house that sits empty part of the year gives mice a quiet place to move into the attic and crawl space, and a roof leak can soak insulation for months before anyone notices. New material over droppings or wet insulation just buries the problem, so we pull the bad stuff out first, and if the roof is still leaking, I'll tell you to get that fixed before you spend a dollar on insulation.

Call or send the form
Call (775) 447-1072 or send the form with your address and what's bothering you, such as a cold room, a high bill or an attic nobody's opened in years. If it's a second home, tell us who can let us in.
I look at the house myself
I go up into the attic and under the floor, and note how many inches are already up there and what shape they're in. Then I walk you through what I found and what should be fixed first.
We check with the Building Division
Before work starts, we ask the division what your job needs and take care of the permit if there is one. We'll tell you what they asked for, so you're not left guessing.
Prep, seal and install
Our small crew protects the path to the attic, and I'm on the job with them. Before anything gets sealed, I check that the furnace, water heater and any gas or propane appliances will still get the fresh air they need.
Walk the finished job together
When the install is done, we walk it with you so you can see the sealed gaps and the even coverage for yourself. I'll point out anything worth keeping an eye on, so you know your house a little better when we leave.
A closer look at insulation work
Truckee insulation questions we hear
Do I need a permit to add insulation to my house in Truckee?
It can, depending on what the job involves, so we find out from the Building Division before work starts. If insulating your walls means replacing or repairing drywall, that's work the division's Building Permits page lists as needing a permit. An undated handout from the division also exempts some small nonstructural work under $1,000 in total valuation, figured as three times the material cost, but because it carries no date, we confirm with the division instead of leaning on it.
How do I apply for a building permit in Truckee?
Building permits in Truckee are submitted and managed through Cloudpermit, the Town of Truckee's online permitting system. The older eSuite system is no longer available for building permits. When your insulation job needs a permit, we take care of it for you.
How much does it cost to insulate an attic in Truckee?
Your price is set by how much attic there is, what has to come out before anything new goes in, and which material fits the house. Old insulation full of droppings or soaked by a roof leak adds a removal step, a tight attic with a small hatch is slower to work in, and closed-cell foam, a dense foam that also blocks moisture, costs more than topping up loose fill. At the estimate I'll walk you through what your house needs now and what can wait.
What causes ice dams on roofs in Truckee?
Ice dams usually start with heat leaking out of the house into the attic, which warms the roof and melts the snow from underneath. That water runs down to the cold eaves and freezes, and the ridge of ice backs up the next melt under the shingles. Sealing the air leaks and keeping insulation even out to the edges, with the eave vents clear, goes after the cause instead of the ice.
How long will the crew be in my attic, and when can we go back inside?
The time in your attic comes down mostly to its size, how easy it is to get into and whether old insulation comes out first, and I'll give you a straight picture of that at the estimate. With blown-in insulation, most people stay home while we work. With spray foam, you, the kids and the pets stay out until the re-entry time, the point the foam maker says it's safe to come back in.
Is spray foam or blown-in insulation better for a Truckee cabin?
For most attics, sealing the gaps and topping up blown-in insulation is the better buy, because it stops the draft for a lot less than foam. Spray foam costs more and seals air while it insulates, so it starts to earn its price when your ductwork runs through the attic and would otherwise sit out in the cold. Under the floor, closed-cell foam can be the right call when moisture is part of the problem.
