BIO recommended calling Krill@SpauldingDecon. He came out to look at the mold in the kitchen ceiling, then recommended John Watt from GoodHousingkeeping in Redwood City. The process was well organized. John Watt made our kitchen look like new!

We had an emergency, a plumbing, leak and water damage, as well as some mold. They were prompt in their response, courteous in their customer service, knowledgeable in their work, and responsive. All in all, they did a great job. Some of the items on the bill were a little pricey, but a very good option to handle an emergency circumstance.

This company deserves 5 stars across the board. They eliminated the black mold and smell from my sunroom. The mold had gone through the carpet as well as some old, worn-out furniture. They removed both and disposed of all the affected items. I had picture albums and historic pictures of my parents that they took into my backyard and patiently wiped down and disinfected. I was happily amazed how thorough they were in their work. I then hired them to empty my dad's attic which he used to hoard a lot of items that had not been looked at in 40 years! Spaulding brough each item down from the attic and took them all away for disposal. Kirill and Mike are such professionals. I would give them more than 5 stars if I could. So glad I found this company and recommend them highly. Hire them! You will love the result of their work.

Review is really for John Watt with Good Housekeeping, to whom I was referred by Spaulding Decon (who did not have capacity). John was punctual, professional, and very easy to deal with. Work was done on time, to expectation and faster than promised. Expensive but worth it, would hire again.

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.
