Insulation removal in Santa Rosa CA - a clean attic ready to insulate again
If your old attic insulation got wet, smells musty or has rodent droppings in it, we take it out so the next layer starts clean.
What's involved in getting old insulation out of my attic?
Insulation removal in Santa Rosa means taking the old insulation out of your attic once it has become the problem, which also leaves the ceiling clear so gaps can be sealed and wiring or ducts fixed before anything new goes in.
Most calls I get about this start with a hot upstairs, a power bill that keeps creeping up or droppings someone spotted by the attic hatch, and the real question is whether what's up there can stay. The price mostly turns on how big the attic is, what kind of insulation is in it and what shape it's in, and the schedule depends on what I find once I'm up there, like wet framing, old wiring or something that needs a different contractor first. You'll get your own figure from the estimate, after I've seen the attic myself.
How we handle insulation removal
I start in the attic with a flashlight, checking how many inches are already up there, whether it's dry and clean, and whether rodents, water or smoke got into it, and then I tell you straight whether it's fine to build on or should come out. If any of it looks like vermiculite, we leave it alone and point you to a separate asbestos abatement contractor, because that's work for a specialist and not for us. When the old material does come out, our crew vacuums out loose blown-in, the fluffy fill that was blown through a hose, and pulls batts, the rolled blankets, out by hand, which takes longer. With the attic floor bare, that's the right time for air sealing, closing the gaps around light fixtures, pipes and the hatch, because new insulation laid over a draft just keeps fighting it.
Pulling insulation out sometimes points to work in other parts of the house. If the floors are cold too, we can look at crawl space insulation while we're there, and if a room stays drafty after the attic is done, wall insulation is usually the next thing to check.
Why Santa Rosa homeowners call D&R Santa Rosa Spray Foam Insulation for insulation removal
I look at every attic myself
I come out to see each job in person before we put a number on it. Our install crew does the work with me running it on site, so the person who looked at your attic is there when the old material comes out.
Steps in order, written down
I learned insulation and air sealing on a municipal crew working on city buildings, and I started this business in 2023. That work taught me to do things in order, write things down and get each job past an inspector, and I run removal jobs the same way.
Licensed and insured on every job
We're licensed and insured. Contractors working inside Santa Rosa city limits also need an active city business license, so it's fair to ask anyone you're comparing to show theirs.
On a removal, what matters is knowing what's in the attic before anyone pulls it out or covers it over. Call (707) 508-4085 or use our contact page, and I'll come take a look.
Get your old attic insulation checked before it comes out
We reply to calls and messages within one business day, and the estimate is free, done at your home, with no obligation. After you send this, we'll set a time for me to come look at the attic, and it helps if you can tell us the rough size, what kind of insulation is up there and any signs of rodents, leaks or vermiculite.

Questions before you book insulation removal
Should I remove old attic insulation or just add more on top?
If it's dry, clean and still deep enough, it's usually doing its job, and one removal company's guide notes that adding a new layer on top is often cheaper. That same guide says removal makes sense when rodents have nested in it, it got wet or smells of mildew, or smoke or fire damage reached the attic.
How much does attic insulation removal cost in Santa Rosa?
Professional attic insulation removal across the US usually costs about $600 to $1,200 per project, and that's a national figure, not a Santa Rosa quote. Removal is priced by the square foot, so a bigger attic costs more.
What should I do if my attic has vermiculite insulation?
Leave it undisturbed, because the EPA says disturbing vermiculite could release asbestos fibers into the air, and it strongly recommends homeowners not try to remove it themselves. Vermiculite is a pebbly pour-in fill, usually gray-brown or silver-gold, and if you choose removal, the EPA says a trained, accredited asbestos abatement contractor should do it, separate from whoever assessed it. In California, a contractor doing asbestos work on 100 square feet or more needs the state's asbestos classification and has to be registered with the state, so ask to see that registration.
Do I need a permit for insulation removal in Santa Rosa?
The City of Santa Rosa requires a building permit unless the California Building Code expressly exempts the work, so check your job with the city's building permits office. When a job needs one, we apply for it, set up the inspections and give you a copy of the paperwork for your records.
How do I get my attic ready for insulation removal?
Clear out the boxes and anything else stored up there, and keep the hatch and the path to it easy to reach so the crew isn't working around your things. If you've seen mold, water stains or signs of pests, jot them down and tell me when I come out, since that changes how we plan the job.
What is the safest way to deal with rodent droppings in attic insulation?
The safest first step is not to sweep or vacuum it up yourself, because CDC cleanup guidance says doing that to rodent urine, droppings or nesting material can put tiny droplets carrying viruses into the air. If rodents nested in your attic, ask any crew you're considering how it handles that waste, and I'll walk you through how we'd handle it in your attic before any work starts.
Other work that often follows removal
- Crawl space insulation
Old insulation under the floor can sag, get wet or hold the same rodent mess as the attic, and it's worth checking while we're already looking at your house.
- Wall insulation
Many older houses have little or nothing inside the outside walls, so even a well-done attic leaves part of the heat loss untouched.
