Verified record
G. Spaulding Basement Waterproofing is a Haverhill operation run by Greg Spaulding, a sole proprietor the Better Business Bureau says has been in business since 1987 — about 39 years. The BBB's page lists a Home Improvement Registration and a Construction Supervisor License for the business, though those are BBB-reported credentials rather than a state registry check, and the BBB itself rates the profile 'Not Rated' for lack of information rather than as an accredited business. The two written reviews on file, both from 2024, describe the same pattern: a fast, free estimate and quick scheduling. A September 2024 review from a fellow small business owner called Greg the guy to call for basement water issues, while an April 2024 review, which came by word of mouth from a neighbor, said he's been working on basements since the 1980s. With just two reviews on file, it's worth asking for a couple of recent references directly, especially given how long Greg says he's been doing this work.

As a small business owner myself I know how critical customer service and pricing is and Greg is definitely the guy you want to call for your basement water issues! He showed up for a free estimate got me a quote nice and fast and once agreed got us on the schedule right away. He showed up on time and got the job done in one day. Everything turned out exactly as he said it would and left the work area clean. His pricing was more than fair and his work was fantastic. Will definitely be recommending him to anyone who asks!
I found out about Greg via word of mouth from a neighbor and I’m glad I did. Greg is very friendly and easy to work with, he came out right away and was able to get me on the schedule so fast I almost didn’t have time to prepare. He’s been working on basements since the 80s and has seen absolutely everything. Once he explained all the work that was needed down in my basement I was expecting his estimate to come in much higher than it did. Every home repair should be this painless.
