Keeping It In The Family…

Fresh-homePaul’s son Dan joined the business in 2008; together they wanted to change the landscape of the industry with the aim to develop a unique family orientated service – the RAQ was born. In earlier 2013, Jonathan McDavid, a respected OSHA Certified Mold Inspector (and grandson of Paul) joined the business. The company has continued to thrive and now serves Wellesley, Newton, Natick and Needham.

We understand that people want affordability, professionalism and no jargon! We keep our home owner informed throughout the process and provide understandable documents on completion of the work.


If you are experiencing issues with mildew and odors, have a need for mold testing or even allergy testing; our indoor air quality specialists are here to help.
