Peter Marini is the Waltham mason customers call back for the second job. In an August 2019 review, a homeowner said the new brick front walkway came out so well they immediately hired him for a large brick patio with stone walls; a September 2020 customer had him return to replace a slate walk with a custom cobble paver entry. Angi and HomeAdvisor list the business as an approved pro with 44 years of experience and Spanish spoken, and Houzz lists a license (#16-164) and 32 years' experience. The written history is 14 reviews from 2017 to 2023, every one five stars, spread across Angi, HomeAdvisor and Houzz. The word that keeps coming up is perfectionist: a 2019 HomeAdvisor customer handed him the patio planning and was glad she did, an October 2021 reviewer used the same word, and a 2019 customer said Peter drove him to see nearby work before he signed. The jobs are walkways, patios, steps and walls, with a heavier side: a 2017 Houzz reviewer described a very large stone retaining wall finished on time and on budget, and September 2023 and 2017 customers had fieldstone foundations repaired and waterproofed, one with a concrete slab added to manage water. Price comes up only as reasonable: a June 2021 reviewer called the work outstanding at a reasonable price, and a 2023 customer with a big hardscape project said it was worth every cent. Even a 2021 homeowner who only needed a consult said he went out of his way to help. Nothing on file is newer than September 2023, and the listings say no warranties are offered, so ask what happens if a step or wall settles. For a brick or stone walkway, a patio with walls, or a fieldstone foundation repair where you want the owner designing and laying the stone himself, this is a well-supported call; get the free estimate and pin down the schedule, which past customers said he kept.
Prompt estimate. Fast, quality work repairing and waterproofing fieldstone foundation. Also laid a concrete slab to help with water management around foundation. Would hire again.
Peter did a great job repairing my brick front steps. Very pleasant to work with. The steps really look like new!!
The most detail oriented, thorough, honest, respectful, punctual, amazing worth every cent and more group around. The work was outstanding. We will hire them again and we hope that this review supports anyone apprehensive about there project.. Ours was a big project. We had hardscaping, material removal and a driveway do-over. I'm just a couple of weeks out house was transformed. It will certainly increase in value, but more than that, our yard will be a haven for us to enjoy for the remainder of our years .
Paul was great! We only needed a consult but he went out of his way to help. Would hire him when we start the work.
Excellent work and prompt follow-up. Peter is a perfectionist!
