Our History

A Quarter Century of Dedication

Founded in 1991, Thompson Waterproofing, Inc. (TWI) is a family owned and operated company that has dedicated a Quarter Century to customer satisfaction, quality craftsmanship and safety.

While family members joined the business and with more than 30 dedicated employees to help it grow, expand its reach and service offerings throughout Eastern Massachusetts, TWI has evolved to become a premier SOMWBA and DCAMM Certified General Contractor specializing in façade restoration. Through a willingness to adapt, a commitment to quality service and a dedication to family values and its employees, TWI has managed to succeed during some of the country’s most turbulent times.

Today, with a 25 year track record of quality service, we have completed hundreds of projects from straightforward to multifaceted including commercial, industrial, institutional, educational and historical buildings for federal, state and municipal agencies, private developers and property managers making TWI one of the most respected Masonry Restoration and Waterproofing specialty contractors in Massachusetts.

TWI proudly continues to set the standard for excellence in its industry with a talented team that has more than 75 years generational experience to deliver quality work on time and within budget while keeping Client Satisfaction, Quality Craftsmanship and Project Safety first.
