TC Hafford Basement Systems

TC Hafford Basement Systems is a Portsmouth-based contractor that says it has offered basement waterproofing and crawl space repair since 1991, working across the Greater Portland, Maine area and eastern New Hampshire. It operates as an exclusive Basement Systems dealer and an authorized Supportworks dealer, and also installs the Gutter Shutter gutter system, alongside foundation repair, concrete leveling, and insulation work. There isn't much of a public track record here yet — one Reddit account and the company's own description of its scope. In a February 2026 post in r/newhampshire, a homeowner said they paid $43,000 for what they called "the full treatment," addressing issues they felt should have been fixed 20 years earlier, before putting the house on the market. That's a five-figure, comprehensive job rather than a quick patch. With only that single account on file, anyone considering work at this scale should get a detailed written scope and ask about warranty terms directly, since nothing beyond the company's own description speaks to how a smaller or more routine job typically goes.
