Stronghold Foundation & Waterproofing

Water pouring into a basement during every rainstorm, then stopped for good -- that's the kind of call Stronghold Foundation & Waterproofing gets in Quincy. The company works out of Canton and says it covers Massachusetts, New Hampshire, and Rhode Island, handling basement waterproofing, French drains, foundation repair, and chimney and masonry work. It describes itself as family-owned, though its own site gives two different ages for the business -- a 1980 founding date on one page, '2 Decades of Experience' in a tagline on another -- so exactly how long it's been around isn't something to take at face value. On Google, it's holding a 4.7 out of 11 ratings, and on Angi a 5.0 across 4 more; the specifics behind those numbers line up with what it advertises. A customer whose basement was taking on water during every storm says the crew installed a full perimeter drainage system and stabilized the foundation walls, checking in more than once to make sure the fix held. Others hired the same team for a stuccoed, waterproofed basement and for chimney leaks, coming away citing fair pricing and on-time finishes. Not every job went cleanly: one customer who paid for both a chimney rebuild and basement waterproofing ran into real problems afterward -- dust from the chimney demo got into the windows, the furnace and washing machine stopped working, and the driveway ended up marked from a ladder -- though the company refunded the service calls involved. Its Massachusetts home improvement contractor license, #217725, is active and confirmed directly with the state registry, and Angi separately lists the same number with an expiration in December 2027. Before booking, it's worth asking how a job site will be protected from the kind of collateral damage that one basement-and-chimney customer ran into, and getting any refund or make-good policy spelled out up front. For a homeowner dealing with an active leak or a foundation that needs stabilizing, the drainage and waterproofing track record here is the strongest reason to call; chimney and masonry work has also come through with 5-star finishes, just with less cushion given how few reviews back it up.
