Pretty much EXACTLY what I want from a professional. Clear communication, timely service, transparent breakdown of cost. He took care of our mold problem, did a thorough clean-up, and even saved me from getting a parking ticket :) Would hire again. Hope to never have to though.

Response from Company:

Thank you for your high rating of our services!

Very responsive. Accommodated my schedule. Appeared on time and evaluated the project and provided a written bid that evening. Discussed the bid with me and completed the job on time and in a workman like manner. Very professional.

Response from Company:

Thanks, Mariam for a high rating of our service.

We had a time-sensitive mold problem with other repairs depending on this being done first. They fit us in promptly to their schedule and were very professional and thorough in their work. Protected the area from damage and cleaned up completely. Would hire them again for a similar problem.

Response from Company:

Thank you, Mark! It was truly a pleasure to assist you.

They were friendly, clear about explaining the work to be done and the cost involved. They timed the work as promised and the cost was reasonable. When tenants noticed that a couple of spots had been missed, they came out within hours to fisx the problem! I have been very impressed by their professionalism. Highly recommended. 5 stars.

Response from Company:

Silvano, thank you for trusting us with your tenants' wellbeing. I am glad we were able to help.

Calm, collected and apparently thorough, because mold smell is gone. He also asked a contractor to call me for collaboration. Contractor didn't call, but I don't blame Spaulding Decon. Definitely would recommend. An on-time, professional job.

Response from Company:

Thank you for your high rating of our services! Please don't hesitate to reach us in the future.

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.
