Advance Concrete Construction is a Marlborough excavation and concrete contractor built around one name that shows up in review after review: owner Elberth Silva, who reviewers credit directly for keeping foundation and site work jobs on schedule and up to code. The company, incorporated in 2014, builds foundations and concrete flatwork for residential and commercial projects across Boston and Middlesex County, and also takes on larger commercial concrete and earthwork jobs — its Procore Construction Network profile shows an average project size north of $6 million. BuildZoom lists an active Massachusetts Home Improvement Contractor license (#181133) for the company. Fourteen of its fifteen reviews on file are five stars, and several describe specific jobs. A 2026 review credits Elberth's crew with excavating, pouring the foundation and finishing the floor for a 36x20 addition. A 2025 review describes the crew showing up for every phase of a project and handling extra work the homeowner hadn't planned for, and another from mid-2025 praises the team's consultative, code-first approach and describes them finishing on schedule. Google shows 4.8★ from 19 ratings, and the company's Better Business Bureau file carries an A+ grade. One outlier is worth flagging: a 2023 review describes what the customer called the worst customer service they'd seen, with unreturned calls and a voicemail that stayed full. It's the only negative account on file, surrounded by reviews describing responsive, communicative service, but it's worth confirming upfront how quickly they return calls during a busy stretch. For foundation, excavation and concrete flatwork on an addition or new build, Advance's reviewers describe a crew that shows up, stays on schedule and communicates clearly through the process.
Elberth and his crew did a fantastic job on the excavation, foundation and floor of my 36x20 addition. Will definitely use again for future work!
