Professional, on time and thorough! I cannot say enough good things about them! They were quick to respond, got the job done and I felt very well taken care of. I’m referring everyone I know to them because they are worth it!

After having a terrible experience with another company, Cube came in and made everything right. Great job!!! Would highly recommend.

5.0 Alexis L. Seattle, WA

We needed to add insulation in the wall, attic and floor. We gather several bids before committing to any of the companies. I decided to go with Cube Insulation because I was very impressed with Sergio, Who came to do the estimate. We ended up adding more scope to the work when I realized they could do duct work as well, so I smashed two potatoes with one fork! Overall, I'm very happy with their work and would definitely hire them again if needed.

5.0 Robert B. Poulsbo, WA

We couldnâ t be happier. They responded quickly with an estimate the work was done quickly and efficiently and appears to be excellent quality. We had Insulation blown in from the exterior siding and we were impressed with the careful handiwork of the young man who did the spackling around each would plug to match the siding.

5.0 John M. Port Orchard, WA

5.0 Corrie L. Bremerton, WA

I added an addition to my house. After the insulation was complete, the general contractor, the electrician and the plumber went out of their way to ask for the name and number of the insulation company. Very impressive work. Plus, it was fast and inexpensive.

Seal of Approval

What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.
  3. Verification of State Business Filings
    For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located.
  4. Criminal Records Search
    HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
  5. Sex Offender Search
    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
    We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
  7. Legal Search for Civil Judgments
    We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them.
  8. Liens Search
    We use 3rd party data sources to check the principal/owner of the business for liens placed against them.
  9. Identity Verification (SSN)
    HomeAdvisor verifies the social security number(s) of the owner/principal for identity check purposes. This check applies primarily to smaller business entities.
  10. Identity Verification (Reverse Phone Lookup)
    We conduct a reverse business phone lookup to identify records matching the phone number information provided by the business.
