Insulation contractor services in Santa Rosa, CA
D&R Santa Rosa Spray Foam Insulation is an insulation contractor in Santa Rosa with 16 services for drafty rooms, cold floors and high power bills. Price and schedule turn mostly on how much old material comes out, what needs sealing first, which material you pick and how easy the space is to reach, and your free estimate lays that out.
Spray foam insulation
We spray foam that expands into gaps as it goes on, so it insulates and seals air in one step, which suits attics with ductwork running through them.
Attic insulation
If the upstairs gets hot or the power bill keeps climbing, we check the inches already in your attic, seal the gaps and bring it up to an even depth.
Blown-in insulation
Blown-in insulation is loose fill we blow through a hose across the attic floor, a good fit for topping up an older attic once the gaps are sealed.
Home insulation
For a house that feels drafty all over, we look at the attic, walls and crawl space together and fix the weakest spots in the right order.
Insulation removal
When old insulation is soaked, matted or full of droppings, we vacuum it out and haul it away so new material doesn't go on top of the problem.
Crawl space insulation
Cold floors usually trace back to the crawl space, so we insulate between the floor joists under your house and fasten the material so it stays put.
Wall insulation
We add insulation to walls in older homes that were built with little or none, filling the cavities through small openings rather than opening up whole walls.
Air sealing services
We find the leaks that make a house drafty, around plumbing, wiring and holes cut through the floor, and close them so your heating and cooling stay inside.
Basement insulation
We insulate basement walls and rim joists, the band of framing that sits on the foundation, so the rooms above and any finished space downstairs feel less cold.
Closed-cell foam insulation
Closed-cell foam is a dense foam that also blocks moisture, so we use it where water or damp air is a concern, like crawl spaces and rim joists.
Open-cell foam insulation
Open-cell foam is softer and lighter than closed-cell, and we spray it into attic rooflines and walls where you want air sealing and quieter rooms for less money.
Commercial insulation
We insulate offices, shops and other commercial buildings for property managers and owners, scheduling the work around tenants and keeping the paperwork in order.
Crawl space vapor barrier
A crawl space vapor barrier is heavy plastic laid over the dirt under your house, which helps keep ground moisture out of the floor framing and insulation.
Vapor barrier installation
During a remodel or addition, we install vapor barriers on the correct side of the insulation in walls and ceilings, so damp air doesn't collect inside the framing.
Attic air sealing
Before any new insulation goes in, we seal the gaps around can lights, pipes and the attic hatch, since covering a leak only hides it.
Retrofit insulation
Retrofit insulation means adding to a house that's already built and lived in, so we work around finished rooms and existing wiring instead of starting from open framing.
Why homeowners choose D&R for insulation
I look at your house myself
I come out and check the attic, crawl space or walls before we quote, so the estimate fits your house and isn't a guess.
Questions answered in plain words
We take the time to walk you through your options, so you know what you're paying for before you agree to anything.
Problems fixed before they're covered
We deal with wet or dirty insulation and open gaps first, because new material laid over a hidden problem is hard to undo.
Trained on a city crew
I learned insulation and air sealing on city buildings, where every job had to pass an inspector, so we write things down and check our work.
Licensed and insured for your job
We're licensed and insured, which matters because only licensed contractors or owner-builders can get building permits in Santa Rosa.
Even depth, eave vents left clear
We keep insulation as deep at the edges as in the middle and leave the eave vents open, so your attic can still breathe.

Your insulation questions answered
How much does attic insulation cost in Santa Rosa?
The cost depends on the size of your attic, what's already up there and which material you choose, so we give you a figure after a free look at your house. Hauling out old insulation, sealing gaps first and a tight space to work in all add to it.
Why does spray foam insulation cost more than blown-in?
Spray foam costs more because it seals air and insulates in one coat, while blown-in insulation only insulates. For most attics, sealing the gaps and topping up blown-in insulation is the better value, unless your ductwork runs through the attic.
How long will the insulation crew be in my attic?
That depends on how big the attic is, how much old material has to come out and how much sealing comes first, and your estimate will show the order of the work. Removal and sealing usually take longer than laying the new insulation.
Do we have to leave the house during spray foam insulation?
For spray foam, yes, you, your kids and your pets stay out until the re-entry time the foam maker sets, the point when it's safe to come back inside. We go over that time with you before the job is booked, and blown-in insulation and air sealing usually don't mean leaving home.
Does an insulation contractor need a license in California?
Yes, in most cases, because California requires a license from the Contractors State License Board when a job needs a building permit, uses employee labor, or totals $1,000 or more in labor and materials. Contractors working in Santa Rosa also need an active city business license, and we're licensed and insured.
Do I need a permit to insulate my house in Santa Rosa?
It may, so check with the city before work starts, since Santa Rosa requires a building permit for work that alters or repairs a building and only licensed contractors or owner-builders can get one. You can ask the city's Building Division, and when your job needs a permit, we apply for it and set up the inspections.
Do you guarantee your insulation work?
Yes, our insulation work is backed by our satisfaction guarantee. If something about the finished job doesn't look right to you, ask us, because we'd rather explain it or look at it than have you wonder.
Should old insulation be removed before adding new insulation?
Only when it's wet, matted or full of droppings, because new insulation laid over a problem keeps the problem in your attic. Clean, dry insulation can usually stay, and we tell you which you have once we've looked.
