Fieldstone Foundations & Masonry Corp is a Boston, MA company built around exactly what its name says: foundation and masonry work, including fieldstone, brick, and stone. Self-reported years in business range widely by platform — Angi says 30 years, a Thumbtack overview says 28, and the owner's own text puts it at 20, dating back to 1998. The one written review on file, from 2024, describes exactly that kind of job: a fieldstone foundation repair that stopped a basement from leaking and letting in pests, with the reviewer calling Karl and the crew honest to deal with. Houzz shows a 5.0 average from two ratings and Thumbtack a perfect 5.0 from one; beyond the numbers, its Thumbtack profile displays photos from 258 projects and Houzz another 10. Two things are worth confirming before booking: its Houzz page currently carries a 'Business Profile Suspended' notice, and BuildZoom lists a Massachusetts mason license (#212642) for the company that's worth checking directly with the state registry. Angi separately lists them for basement and crawlspace waterproofing and foundation repair, offering free estimates. Worth a call for a foundation or masonry job, especially one involving an older fieldstone or stone foundation. Confirm the mason license status directly with the state, and ask to see photos from a project like yours before signing anything.
Typical Greater Boston range for this kind of work, from regional averages — not a quote from FIELDSTONE FOUNDATIONS & MASONRY CORP. Use it to sanity-check bids, then get the real number in writing.
Not sure which you need? Start with an inspection — many reputable companies assess free, and independent assessments run up to $500.
The wall run getting the drain — a full 30×40 ft basement is about 140 ft.
