Folan Waterproofing & Construction has been sealing and rebuilding masonry out of South Easton since 1969 — "57 years in business, three generations," as the company puts it. Its site describes a women-owned family business built around masonry restoration, historic preservation, and waterproofing and sealants for building construction projects, with Holly Brookes as president and Patrick J Folan and Aimee Foley as vice-presidents. Massachusetts lists the company's Women Business Enterprise certification as active, good through 2028, and the site also cites WBE/DBE certification in Rhode Island and OSHA 30-hour training for its foremen. Its Better Business Bureau grade is A+. On Google the company averages 4.7 across 14 ratings, where a March 2025 reviewer summed it up as "your waterproofing experts." A November 2021 reviewer tells a harder story: hired for a restoration on a mill building in Brockton, that customer called the staff rude and unprofessional, said specific requests from the architect and the conservator were ignored, and wrote that the crew did the bare minimum and left the project unfinished. A Boston Globe piece from December 2021 looked at the company from the inside instead, describing a third-generation restoration and waterproofing outfit whose treatment of its people had earned it loyalty from its employees. One thing to sort out early: the work Folan advertises, and the one job a reviewer described at length, is building-scale — a Brockton mill, sealants on construction projects, historic fabric. A homeowner calling about a wet basement or a failing chimney should ask first whether Folan takes residential jobs of that size. If your job is masonry or waterproofing with preservation stakes, this is the kind of shop built for it. Before signing, ask who will run your project day to day, how a designer's or architect's change requests get tracked, and what counts as finished on paper.
“This third-generation restoration and waterproofing company in South Easton is dedicated to treating every employee with respect and support. It's an attitude that has earned Folan tremendous loyalty from its employees, some of whom were already working there when the current owners were children.”

Your waterproofing experts.
Folan worked on a restoration project for us on a mill building in Brockton. The staff is very rude & unprofessional. They ignored many of the specific requests the architect and conservator had called out. They did the bare minimum and never finished the project to satisfaction. For the cost we expected a much more professional job and had to hire another contractor to fix their mistakes. Avoid this company!
