Zacarias Excavation is a Lynn, MA excavation and masonry outfit run by Nelvin Zacarias — about seven years in business per its Angi and HomeAdvisor profiles — doing everything from boulder removal and retaining walls to driveway paving and, in winter, snow plowing. Its most recent Google reviews, from June and July of this year, describe a large granite boulder removed and a full excavation-and-foundation job finished on schedule with attention to detail. Older reviews fill in the range of the work: a 2023 review describes a 120-foot retaining wall and a full backyard releveling project, with the owner picking materials and following engineering steps; a 2024 review describes a stone-and-cement retaining wall in Winchester that came out 'exactly like we hoped for'; and several reviews from the 2025-2026 snow season, on Google and Thumbtack, describe plowing that started within hours of a storm with steady updates along the way. One September 2025 Google review is sharply negative — it describes a driveway install with weeds coming through within a month, loose aggregate, and a cracking stone border, says the company would not return calls to fix it, and warns to check around before hiring. The BBB separately grades the business B-, citing its failure to respond to one filed complaint. Thumbtack's own profile is also inconsistent about how long the company has operated — the page overview says seven years, the owner's own About blurb says four. Worth asking directly about the driveway and paving side of the work given that complaint, and confirming who you'd be dealing with day to day — the boulder-moving, retaining-wall and snow-removal side of the business has a much more consistent track record.
Nelvin and team did an amazing job for us. Had to remove a large granite boulder. Excellent work. I highly recommend.
I highly recommend Zacarias Excavation & Concrete Foundation. Their team was professional, reliable, and delivered high-quality work from start to finish. The excavation and foundation work was completed on schedule, and their attention to detail was outstanding. Communication throughout the project was excellent, and they kept the job site clean and organized. If you’re looking for a trustworthy company that takes pride in their work and delivers great results, Zacarias Excavation & Concrete Foundation is an excellent choice. Thank you for a job well done!
Had a great experience with Zacarias Excavation. They moved 6-7 boulders from one area to another and did an outstanding job ensuring the boulders were stable oriented correctly and ensured we were happy with the work. Would hire again.
We had a great experience with Zacarias Excavation’s snow removal services. After the snow last week, we decided our shoveling days are over lol. Our summer lawn ppl wanted an outrageous contract to pay whether it snowed or not. Looked online and found a number of businesses. Melvin from Zacarias quickly returned our call & said we’d be “on his list” after checking out our property on Google Maps. When we woke up to all the snow today, Melvin kept in touch, and updated all day on his location. He arrived late afternoon, and he and another guy were in and out in about 15 minutes. Great results. Fair price. Easy to work with. Would highly recommend.
I needed quick help with snow removal and they came through. Very responsive as soon as I requested a quote, great communication pre-arrival, during the job and after, and they cleared my driveway and walkway rapidly. Would recommend them and use them again.
