Foundation Crack Seal

A December 2025 customer had been through the other basement companies first: hard sell, a 30-minute presentation, the whole thing reminding them of a timeshare seminar. Then Garrett turned up — punctual, transparent, and by their account nothing like that. Foundation Crack Seal works out of Millis across MetroWest Boston. It is owner-operated, with the owner on every job by the company's own account, doing crack injection, waterproofing and stone repointing; the site advertises a 10-year transferable warranty. Its Angi profile carries an Approved badge and notes ten years of experience. Thirty written accounts run from 2021 to 2026, and the old-house work is where the detail sits. In September 2022 the owner of a small old house with a fieldstone foundation — cracks and wide gaps between the rocks — said Garrett responded right away and had crews working within three days. A January 2023 client with a fieldstone multi-family had several gaps and exterior settlement cracks dealt with. In October 2024 an owner of a 100-year-old two-family, where the stone foundation meant much of the digging had to be done by hand, went ahead with a drainage system. The newer accounts describe a tight process. A June 2026 client got a quick quote, a slot inside a week, an online payment option and answers to follow-up questions after the work was done. An April 2026 client said the crack repairs were pressure tested before Garrett wrapped up, and have held. In October 2025 a customer living an hour away had the problem assessed and fixed within 72 hours, and another that month said Garrett and his brother sealed the gaps around a waste pipe running out to the septic field so quietly that nobody realised they were in the basement. The work runs past the classic wall crack: an August 2023 job sealed the garage wall and floor, the basement and the bulkhead, and a July 2021 customer came here after the company that installed their new bulkhead left it leaking and stopped answering. For a leaking crack, a wet fieldstone wall or a bulkhead that seeps, this is a one-owner outfit that quotes fast and turns up when it says it will. Get the warranty terms in writing, and ask whether your repair gets pressure tested before the crew leaves.
