A Concrete Answer, Inc. describes itself as a concrete cutting, coring and foundation repair company working Cape Cod and the South Shore, with epoxy and urethane injection among its methods. The company says it was founded in 1997. A 2024 customer in Barnstable said three areas of a poured concrete foundation leaked, and that the team injected an expanding product into the basement walls and the problem was solved. A 2025 customer said they repaired large cracks in the foundation and around the window wells at a fair price. A 2023 customer wrote that more than a year after the work, the basement was completely dry. The work goes past cracks. A 2024 customer said the company cut the floor for plumbing and then created a walkout basement with two windows. A 2023 customer said the crew arrived on time and repaired a leak around a septic discharge pipe in the basement. A 2022 customer had front stairs resurfaced and wrote: "From the first phone to the finished product it was 2 weeks." A 2026 customer selling a home said Dave, the owner, came to look at an issue from the inspection report, said there was no issue and would not accept payment for the evaluation. A 2023 customer wrote that they offered a 5 year guarantee. Its BBB grade is A+, and it holds 5 stars on Google from 74 ratings. Its Massachusetts home improvement contractor registration, number 126513, is expired on the state registry.

Hands down one of the best companies on the Cape. Don’t look elsewhere. We are selling our home and had an “issue” arise from the inspection report. Becky responded to my phone call and emails instantly and Dave, the owner, fit us into his schedule immediately to take a look. Dave was honest and said there was absolutely no issue and would not accept any form of payment for the evaluation. Wonderful company run by great people which is uncommon nowadays. Thank you!!!!
