Pioneer Basement Waterproofing is a family-owned basement waterproofing, crawl space and foundation repair contractor in Westport, working across Massachusetts and Rhode Island since 1984 — Boston, Cambridge, Newton, Brookline, Quincy, Braintree, Weymouth, Plymouth, Brockton, Taunton, Fall River, New Bedford and Dartmouth among the towns it names. Its Massachusetts home improvement contractor registration, 112382, is verified active in the state registry, and it has been Better Business Bureau accredited since July 1993 with an A+ grade. Steve Andras founded it and, the company says, holds several patents for basement waterproofing technology.
Annual sump pump maintenance is the job most customers describe, and they name the technician almost every time — Alfredo above all, with Johnson, Rick, Carlos, Lemuel, Nathan, Isaac, Steve and Dawson all credited by customers in 2026. A June 2026 customer had a pump cleaned rather than replaced first, to see whether that would fix the problem, and appreciated the attempt even though it did not. Another that month had maintenance and a new dehumidifier fitted on a return visit. A June 2026 customer whose technician has serviced their pumps for several years described the systems being reviewed with them each time.
The bigger installations are described in the same detail. A May 2026 customer had a drainage system installed and had the grade under their deck corrected and deck boards meticulously replaced along the way. A May 2026 customer who collected quotes earlier that year had insulating wall covering and a full-perimeter system installed by a team they called timely and efficient. A March 2024 customer had an old sump pump and a battery backup replaced with external drainage improved at the same time. A May 2022 customer had a sump pump, vapour barrier and collection channel put into a Cape-style home in just over a day.
The work holds up on hard cases: a September 2023 customer had an 88-year-old relative's basement fixed after forty years of leaking, crediting the quote from Rafael, the office staff by name, and the installation team.
One account from March 2023 is worth reading. A customer said a promised credit for a service call did not appear, and that when they queried it the estimate was rewritten at a higher price before the credit was subtracted. A June 2026 customer, otherwise satisfied, called a $199 service charge steep for a two-minute diagnosis. For waterproofing, sump pumps, drainage or crawl space work in southeastern Massachusetts and Rhode Island, the written record is deep, current and specific.
