Water is what brought Parkway Masonry & Construction's happiest customers to them. In February 2025 reviews, one homeowner describes major foundation leaks they had struggled to find anyone to fix, repaired efficiently and at a cost they called reasonable; another says water seeping into their basement was sorted out. A November 2024 reviewer says the North Andover crew showed up on time and did the work on their foundation and chimney at a good price, and reviewers that winter also credit them with a chimney and a set of steps. Flatwork is where the sharp complaint sits. In a June 2026 review, a customer who paid $8,000 for a patio says it has two long, full-depth cracks that are now taking water, that they had been told it would not crack, and that the subsurface was not dug out and prepared. An April 2025 reviewer's whole comment is a caution to be sure you ask the right questions before the work begins. Both the Angi and HomeAdvisor profiles carry the same 4.1-star average from the same eight reviews — six five-star, one two-star, one one-star — and both list Massachusetts trade licence #214705. The categories on those pages are concrete flatwork repair and resurfacing, brick, stone or block wall repair, and foundation, basement or crawlspace waterproofing, with free estimates, emergency service and warranties offered. If your problem is water — a leaking foundation, a wet basement, a chimney — that is what the solved-problem reviews are about, and they are recent enough to mean something. For a patio or any poured flatwork, put the base preparation in the contract: how deep the excavation goes, what goes under the slab and how thick, and exactly what the warranty covers if it cracks.
STAY AWAY FROM JEFF and his crew! I paid $8000 for a patio in August 25.They said it would not crack,.but it now has 2 long and the FULL DEPTH cracks. Water is now going in the cracks also. Not good! They did NOT prepare the subsurface by digging it out and adding 6-7" of sand and crushed rock for the cold environment in NH. Jeff is "ghosting" my Texts and emails to come and look at it and provide a real fix. They are not a professional and certainly NOT trustworthy. I have a 30 year warranty and they will NOT honor it. AGAIN STAY AWAY from Jeff . I will have to pay to demolish and pay for a new patio.as I intended to make it closed in room. What a SCAM!!!! ANGI SHOULD NOT RECOMMEND THEM!
Beware and be absolutely sure you ask them the right questions before the work begins. We were ignorant and trusting both big mistakes with these guys!
Very happy
