Hire the crew that shows you the attic.
Most homeowners never see their own attic. A good insulation contractor shows you what's up there in photos, explains the fix in plain words and quotes every part of the job.

Why choosing an insulation contractor is hard
Insulation is one of the few home projects you can't easily check. The work happens in an attic or crawl space you probably won't climb into, and once it's done, it all looks like a fluffy layer. Two quotes for the same attic can differ a lot, and from the driveway it's hard to tell which one includes air sealing, baffles, the right depth or removal of what's already there.
So the best way to choose is to look at how the contractor works before you sign anything. Do they go into the attic, or quote from the hatch? Do they show you photos? Does the estimate list what's included, or just a number? Super Attic Solutions started as a small family business and grew into one of the most-recommended insulation companies in the Seattle area by doing those things on every job.
Warning signs
What to look for in an insulation contractor
Use this list when you're comparing quotes, including ours.
- SIGN 01
An active Washington license
Ask for the license number and look it up with Washington L&I. Ours is ATTICSI795QZ. Licensed, bonded and insured.
- SIGN 02
They go all the way into the attic
A quote from the top of the ladder misses wet spots, rodent signs and thin corners. The inspector should get in and move around.
- SIGN 03
They show you photos
You should see what they saw: depth, condition, droppings, vents and ducts. Photos make the recommendation something you can check.
- SIGN 04
The quote lists the prep work
Air sealing, eave baffles, hatch work and clearances should be named in the estimate, not assumed.
- SIGN 05
They'll tell you when not to replace
If your old insulation is fine to top up, a good contractor says so instead of selling a full removal.
- SIGN 06
They handle related problems
Rodents, moisture and bath fans venting into the attic all affect insulation. The crew should spot them and deal with them.

How we work with you
From the first call to the last photo, here's what to expect.
- 01
Call or book online
Call (800) 674-4933 or send a request. We're open Sunday through Friday, 7:30 AM to 7:00 PM, and closed Saturday. We'll ask a few questions about the house and what you've noticed, then set a time for a free inspection that works around your schedule.
- 02
Free inspection with photos
A technician goes into the attic, and the crawl space if needed, and takes photos of what's there: depth, condition, vents, ducts, rodent signs and moisture. Then we sit down with you and go through the photos, so you see the same thing we saw.
- 03
A clear, itemized estimate
We recommend a material and target depth and explain why. The estimate lists each part: removal if needed, cleanup, sealing, baffles, insulation and any rodent or moisture work. If a PSE rebate may apply, we check what you qualify for and handle the paperwork with you.
- 04
Scheduled, protected install
Our crew arrives on the scheduled day, covers the path through your house and does the work in the order that protects it: removal and cleanup, then sealing, then insulation. We keep you posted during the job and answer questions as they come up.
- 05
After photos and walkthrough
When the work is done we photograph the attic again from the same spots, clean up and walk you through the before and after. You have a record of what was installed, and you know exactly what you paid for, even if you never climb into the attic yourself.

Puget Sound homes
A Puget Sound insulation company
We're based in Kirkland and work across Seattle, the Eastside and the wider Puget Sound region, from Mount Vernon and Arlington down through Everett, Bellevue, Renton, Kent and Tacoma to Olympia, Lacey and Centralia. That range of houses teaches you things. Older Seattle homes with crawl spaces and knob-and-tube wiring. Eastside tract homes from the 1970s through the 1990s with settled builder-grade insulation. Newer homes that still have gaps at the hatch and can lights. Each of those calls for a different plan, and we've worked in all of them.
Insulation here also connects to everything else in the attic and crawl space. Our wet season brings moisture problems. Roof rats and Norway rats ruin insulation. Ducts, wiring and bath fans run right through the layer. Because we also do rodent proofing, attic cleaning, crawl space vapor barriers and HVAC work, the crew that finds a problem can usually fix it in the same project instead of sending you to someone else. For you, that means one inspection and one schedule.
Pricing
What shapes the price
Every estimate starts with a free inspection. These are the factors that move the number.
- FACTOR 01
Size and access
Attic and crawl space area, roof pitch and how easy it is to get in and move around.
- FACTOR 02
Condition of what's there
Clean insulation can stay. Wet, moldy or rodent-soiled material adds removal and cleanup.
- FACTOR 03
Material and target depth
Which insulation you choose and how far we're building up from the current level.
- FACTOR 04
Prep and sealing
Air leaks, can lights, baffles, hatch work and any rodent entry points to close.
- FACTOR 05
PSE rebates
Any rebate is set by PSE, and its programs change. During the estimate we check what you qualify for and handle the paperwork with you.
We had rodent problem in our house. Also our house had bare minimum insulation in some places. Isaac was very helpful, he also took some photos of the attic and crawl space. They gave me a reasonable quote for rodent proofing and insulation. Their crew was on time and finished the job in two days. Really appreciate their hard work.
FAQ
Insulation contractors for your home: questions we hear
Still unsure? Call (800) 674-4933 and talk it through with us.
How do I check an insulation contractor's license in Washington?
Washington L&I has a free online tool to verify a contractor. Search by name or license number to see whether the license is active and the bond and insurance are current. Our license number is ATTICSI795QZ, and we're licensed, bonded and insured. Check any contractor before you sign.
How many insulation estimates should I get?
Two or three is reasonable. The goal isn't just comparing prices. Compare what each one includes: was the inspector in the attic, did you get photos, does the estimate list air sealing, baffles, removal and depth? A lower number that leaves out prep work usually isn't the better deal.
Is your insulation estimate really free?
Yes. The inspection and estimate are free, with no obligation. A technician goes into your attic, and the crawl space if needed, takes photos and goes through them with you. You get a written estimate that lists each part of the job, and you decide from there.
What should an insulation quote include?
The material, the target R-value or depth, and the area covered. It should also say whether old insulation is being removed, and list air sealing, eave baffles, hatch insulation and clearances around flues and fixtures. If rodents or moisture were found, the quote should say how they'll be handled.
Can you handle rodents and insulation in one project?
Yes. We trap the rodents, seal every entry point we find, remove and clean up the soiled insulation and install new insulation, in that order. You're told what we use and where we put it. Doing it as one project keeps the new insulation from being ruined.
Do you work with landlords and property managers?
Yes. We work with HOAs, landlords and property managers on apartment buildings and rental homes, including insulation, rodent control, attic cleaning and crawl space work. We can inspect several units or buildings and quote them together. Call (800) 674-4933 to talk about your properties.
