Verified record
TWC Phoenix works out of a shop on Chesterton Street in Roxbury with roots that go back further than the name suggests. The company says it was formed through a 2023 merger of The Waterproofing Company, a firm incorporated in New York City in 1905 and based in Boston since the 1920s, and Phoenix Bay State Construction, started in Boston in 1974 by Bob Asmar and Bill Whall. By its own account it's now a division of Greenwood Enterprises, a large commercial roofing and building-envelope group. The written record is short: three Google reviews spanning 2022 to 2024. The clearest one, from 2022, is actually about the waterproofing work — a customer called it a good place for waterproofing needs and singled out Chris and the rest of the staff as helpful, noting the business had already been on Chesterton Street for 17 years. A 2024 review simply calls the service professional. The one sour note, from 2023, calls the company unprofessional and rude but doesn't say what happened. Before calling, know that the written history here is thin — Google shows 3.7 stars from seven ratings, but only a handful come with any detail, and the company's own description leans toward commercial waterproofing, masonry, and historic restoration rather than smaller residential jobs. Worth confirming scope and timeline for a home project specifically.
