Homes and small businesses around Calistoga
Calistoga is a small city at the north end of the Napa Valley, and most of the calls we get there come from homeowners with a drafty room, a hot upstairs or an old attic they're not sure about, along with owners of shops and small inns. We're based in Santa Rosa and come over the hill for this work, the same way we head up to Healdsburg and the other cities north of us.
Because so many of these houses have been around a while, the job usually starts with finding out what's already in the attic and under the floor, not with adding more.
Our services in Calistoga, CA
- Attic insulation
Many Calistoga attics have a few settled inches left, so the upstairs runs hot or drafty. We seal the gaps first, then build coverage up evenly to the eaves.
- Attic air sealing
The attics we open here often show gaps around can lights, pipes and the hatch. We close them first, because insulation laid over a draft just keeps fighting it.
- Insulation removal
Older houses here sometimes have attic insulation that was soaked or fouled by rodents. We take it out and look at the framing before anything new goes in.
- Crawl space insulation
Cold floors over a raised foundation usually mean the crawl space insulation is missing or sagging. We fit it snug to the subfloor and seal around the pipes.
- Commercial insulation
Calistoga's shops, inns and offices often have older roofs and walls that leak air. We plan commercial insulation around your hours and the people inside.
- Spray foam insulation
When ductwork runs through a Calistoga attic, spray foam on the roofline brings it inside the insulated space. Otherwise, sealing and topping up usually does the job for less.
What Calistoga houses need before more insulation
A lot of the homes we see in Calistoga have been added onto or reworked over the years, so the attic can change from one end to the other, with a few settled inches over one part and next to nothing over the newer room. That's why I come out and look myself before we quote, checking how many inches are already up there, whether any of it is wet or full of droppings, and whether the eave vents are still clear. What moves the price is mostly how much has to come out and how much sealing the attic needs, and the schedule turns on removal and on whether the job needs a permit.
The shops and small inns in town need the same order of work with more planning, because the space usually stays in use. We work out access and timing with the owner or property manager before the crew shows up, and we write each step down so the work is easy to check later.

Calistoga insulation questions answered
Does a Napa County business license cover insulation work in Calistoga?
No. The City of Calistoga requires its own business license, with the business license tax paid, before any business activity in the city, even for a company based outside the city limits, licensed by another city or holding a Napa County license. So any contractor you hire, us included, needs that city license before work starts in Calistoga.
When does an insulation contractor need a CSLB license in California?
A contractor needs a license from the Contractors State License Board whenever the job needs a building permit, uses employee labor, or the labor and materials on one or more contracts for the project add up to $1,000 or more. A larger project can't be broken into smaller contracts to stay under that amount, so be wary of anyone who offers to split it. We're licensed and insured, and I'm glad to answer any questions about that at the estimate.
Does an addition in Calistoga need Planning review before a building permit?
Often it does, because the city lists additions, new homes and significant exterior changes among the projects that may need Planning Division review before building permits can be issued. Whether yours does depends on the zoning, the type of project and the development standards for your lot, and the Planning Division sees visitors at City Hall, 1232 Washington St., Monday to Friday from 8 a.m. to 4:30 p.m. For insulation on its own, the Building Division is the office to ask, since it reviews permit applications and inspects building work. When a job needs a permit, we apply for it, set up the inspections and give you a copy of the paperwork for your records.
How do I look up past permits for my Calistoga home?
Use the city's permit portal, which finds permit records by address or parcel number. It shows the inspection history and when each permit was issued and given final approval, which is worth a look before we open up an attic or a wall someone else has worked on.
How much does it cost to insulate a house in Calistoga?
The price depends on what's in your attic or crawl space now and what the house needs, and we put a figure on it after I've looked at it in person rather than guessing over the phone. The material you choose matters, with spray foam costing more than blown-in, which is loose fill blown through a hose, and so does how easy the space is to reach and how much old material has to come out. If the insulation is part of a bigger remodel that needs Planning review and a permit, those steps add to the job too.
How long does insulation work keep us out of the house in Calistoga?
For blown-in insulation and air sealing, usually not at all, because the work stays in the attic or crawl space. Spray foam is different, since everyone, kids and pets included, stays out until the re-entry time, the point when it's safe to come back in, and I'll go over that wait for your job before we book it.
