Project: Clean a Roof
Winston ( Owner) came that afternoon we had requested quotes from HomeAdvisor and gave us a fair estimate set a date for our roof and back deck to be cleaned. They did an excellent job. I will definitely use them again.

Wilson and his team did a great job at a very reasonable price. We have had many major wind and rain storms since the Mass & Mass team did the job and have had no issues with water on a flat roofed building.

Project: Clean a Roof
They did a great job, roof looks brand new. The crew showed up on time, did an excellent job and cleaned up all the debris on the house and surrounding area. I’d hire them again.

Review by in Woodinville, WA
Project: Clean a Roof
Late to bidding appointment. They Pushed the work back a day kinda last minute. Said it would be an easy job but the poor one guy doing it was at the house from morning until sunset. In terms of cleaning, the guy pressure washed the house and roof well but there was debris all over the place that I had to clean up. Also, left garbage around the house that I had to clean up.
Response by Mass & Mass, LLC: Mass & Mass is a company that preaches communication and likes to do a good job for everyone. It seems that you did not want to communicate and ask us to finish the clean up for you, which would be done with appreciation. Our co-worker for being dark probably did not see it. Not everything is perfect, we may also have some problems. This "poor guy" you are referring to is a new worker who deserves a chance to learn and have a decent job. When I started my business I used to wash two of these houses a day, that is, it's not a big job, it just needs more experience.

Review by in Bellevue, WA
Project: Clean a Roof
Mass and Mass came promptly, assessed what needed to be down, and were able to do the roof and gutter cleaning within a few days after my request to complete the work as soon as possible. Ed, who did the cleaning ,worked incredibly hard and put in a long day. I would recommend them without hesitation and intend to have them return when I need more done. Thank you Wilson.

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.

NOTE: Member service professional information confirmed as described above may change or expire over time; while HomeAdvisor attempts to maintain accurate and up-to-date information, and confirms changes when notified, we cannot guarantee that profile and screening information is accurate. Therefore, we recommend that before working with a service professional you verify that information presented is still current and/or acceptable to you.
