Oliver Construction Inc

Oliver Construction Inc is a Lowell general contractor run by Diego Oliver that shows up in review after review for one thing above all: plaster and drywall work reviewers describe as unusually clean and precise — "smooth as glass," "you couldn't even tell they had been there." Its Massachusetts home improvement contractor license is active, and the company carries an A+ from the Better Business Bureau. The written record is deep and current — 51 reviews on Google, Thumbtack and the BBB spanning 2021 through this year, with Google alone putting the company at 4.8★ across 71 ratings. Reviewers describe bathroom remodels finished on time and on budget, kitchen renovations, a flood-damage restoration that rebuilt ceiling tiles, insulation and blue-board, and a multi-trade living/dining/kitchen overhaul covering painting, carpentry, electrical and tiling. Several customers mention getting the lowest quote of several they collected and a team on site within days; in a 2024 review, a homeowner describes Diego's crew discovering rotted framing mid-demo and repairing it before the drywall work could proceed, at no surprise cost. Recent activity has slowed to a handful of reviews in the past six months, and one of the three is negative — a 2026 review says the company arrived late, rarely answered the phone, and tacked on extra charges at the end without warning. That's not an isolated account: a 2023 review describes a no-show (told someone was "on the way," then abruptly cancelled at 9:15 for a 7:30 appointment), and a BBB review alleges a more serious dispute — that the company was paid for materials and then didn't show up for two months while asking for more money. Given that split, it's worth pinning down the payment schedule, start date and any change-order process in writing before work begins — the volume of detailed, satisfied customers is real, but so are a handful of accounts describing scheduling and billing problems on the other end.
