Homes and small commercial buildings in Novato
Novato is one of the cities we travel to from our base in Santa Rosa, along with places like Petaluma and Larkfield-Wikiup. The calls here sound a lot like the ones we get closer to home: a drafty bedroom, an upstairs that runs hot, a room over the garage nobody wants to sit in, and a power bill that keeps creeping up.
Most of what we see in Novato is single-family houses, plus some offices and small commercial buildings for the property managers who look after them. Houses here come in a range of ages, and that age shows up in the attic. A newer house might only need a top-up, while an older one can hide problems you won't see from the hatch. That's why I come out and look at every job myself before we quote, because the right order of work depends on what's actually up there.
Our services in Novato, CA
- Blown-in insulation
If an older attic is down to a few inches, we add blown-in insulation, loose fill sent through a hose. We spread it evenly to the edges and keep eave vents clear.
- Attic air sealing
Drafty rooms usually trace back to gaps around recessed lights, pipes and the attic hatch. We seal those first, because insulation laid over a draft keeps fighting it.
- Insulation removal
Older attics sometimes hold insulation that got soaked or filled with droppings. We take it out and clean up before anything new goes in, so the problem doesn't stay buried.
- Crawl space insulation
Cold floors over a crawl space usually mean the insulation under them has sagged or dropped. We check what's down there, then refit it snug under the floor.
- Wall insulation
Rooms that stay cold along outside walls often have little or nothing inside those walls. We can usually fill them through small holes and patch them, without opening the drywall.
- Commercial insulation
Offices and commercial buildings often have the same drafts and high bills as houses, just bigger. I look the building over first, then we plan the work around your tenants.
What an older Novato attic usually needs
In a house that's been around a while, the attic tells us most of the story. We measure how many inches are already up there, check whether any of it got wet or holds droppings, look for open gaps around pipes, wires and the hatch, and make sure the vents along the eaves aren't buried. Then we work in that order, so anything ruined comes out, the gaps get sealed, and new insulation goes in evenly all the way out to the edges, because the edges are where coverage usually runs thin.
Your price comes down to the size of the attic, how much has to come out, how much sealing it needs and which material makes sense. The schedule turns mostly on whether removal comes first and whether the job needs a permit and inspection, and you'll get your own figure once I've seen the house.

Novato insulation and permit questions
Who issues building permits in Novato?
The City of Novato Building Division issues building permits, and it also reviews plans and sends inspectors out to check the work. If you're not sure whether your insulation job needs a permit, the division's forms page has a guide to required and exempt work, or you can call city offices at 415.899.8900.
Which projects can get an instant building permit in Novato?
Some like-for-like residential projects can get a permit issued instantly online after a confirmation step: water heater, HVAC and electrical panel replacements, reroofs, window and door replacements, and bathroom and kitchen remodels. Insulation isn't on that list, so ask the Building Division how your job is handled rather than assuming either way.
How do I apply for a building permit in Novato?
You apply online through the city's Novato Permits portal, and you'll need to set up an account there before you can submit anything. The city also puts permitting, planning and building staff in one place, along with Novato Fire, North Marin Water and the Novato Sanitary District. When your insulation job needs a permit, we apply for it.
How do I schedule a building inspection in Novato?
You request it through the Novato Permits portal, and only for a permit that's already been issued. The person asking has to be a listed contact on that permit, so on jobs where we pull the permit, we set up the inspections and give you a copy of the paperwork for your records.
What license does an insulation contractor need to work in Novato?
A contractor needs a California contractor license, and new applicants have to pass the state licensing board's exams unless one of the board's exceptions applies. The city also requires a business license to do business in Novato. We're licensed and insured, and I'm glad to answer questions about it when I come out.
How much does it cost to insulate an attic in Novato?
There's no fair number until I've seen the attic, because the cost comes down to how much is already up there, whether old insulation has to come out first and how many gaps need sealing. Spray foam costs more and seals air as it insulates, so it's usually worth it when the ductwork runs through the attic. Otherwise sealing the gaps and topping up with blown-in usually gives you more for the money, and I'll walk you through what each part of the estimate pays for.
