5.0 Rob S. Kirkland, WA

Ryan was on time and efficient with our time for the estimate. We have an 1100 ftà  à ² rambler. We wanted to add blown-in insulation over the existing insulation which had settled to the rise of the rafters, very inefficient. His quote came in at the same price as another lowest quote, but with more service built into his estimate. The reason is Insulation Worx is a preferred contractor with PSE, so we received an automatic $700 rebate from PSE. He noted all of the other defects in the attic, and bathroom/kitchen vents that others did (I had 4 estimates total). His crew were on time, friendly, and did all of the work I asked of them, including adding markers for where my canned lights are located, so they would be easier to locate when I do future replacements. They added two dedicated roof jacks for bathroom and kitchen vents, added 2 other vents for added circulation, and cut out birdblock every other rafter, as ours was insufficient. They also air-sealed every canned light and any other place where there was penetration of the ceiling. Adding baffles at all birdblock holes ensured proper attic ventilation, minimizing our chance of developing mold. I have nothing but compliments for the Insulation Worx team!

5.0 Aleth H. Olympia, WA

They are very friendly and did a great job in my insulation.

5.0 Josh K. Kent, WA

They did a great job.

4.0 Larry H. Tacoma, WA

They were the only company to respond to my inquiries (I left messages with 4 other companies). Ryan came right out to quote the job (blow in insulation to exterior wall.) There was some delays in work scheduling due to Covid issues. They did finally come out. The crew was friendly, did their work and they met my expectation.

4.5 Brian C. Lakewood, WA

When Ryan came out to quote the job, he was friendly, knowledgeable, and honest. The crew showed up to do the work on the scheduled day and time as agreed. The blown-in insulation work was done to the agreed upon standard. The work was completed in one day and they did excellent work. Besides insulation I also had them install an attic exhaust fan in the garage that I provided. They did a great job on that as well. The crew was friendly and professional and I would definitely use the company again.

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)
