Two of the write-ups left for Diamond Asphalt spend their words on what happened before any sealer went down. A homeowner writing in January 2021 described years of oil and fuel stains cleaned off the driveway first, and said it looked brand new again. Another, writing in February 2021, credited David with showing up when he said he would, cleaning around the edges and washing the driveway down before applying the sealer, then making sure the job was right before moving on. That is the work here: driveways out of Winthrop — new asphalt, repairs, seal coats. Thumbtack's profile lists David Duff as the owner, eight employees and six years in business, plus a passed background check for him. Durability comes up as well. In an August 2023 review, a customer said asphalt the crew had laid about two years earlier was holding up through heavy rain, and that they were having Diamond back for more work. A July 2023 customer hired them to redo a driveway that had recently been sealcoated improperly, and praised both the work and the price. Price came up again in April 2024, from someone looking back at a driveway sealed the previous October: fair pricing, an efficient crew. A May 2022 customer credited Jim and Mike with a driveway that looked brand new, and a February 2022 reviewer described David as direct and easy to talk to. On r/massachusetts in July 2024, a commenter vouched for the owner. The written history runs 2021 to 2024 — eight accounts across Google and Thumbtack — and the two platforms do not line up exactly. Google's 20 ratings average five stars; Thumbtack's 16 run 94% at five stars and 6% at one. Thumbtack's profile also lists work well beyond paving: masonry, demolition, concrete removal, brick or stone repair, and land leveling and grading. For a driveway that needs laying, patching, or sealing over a job done badly the first time, this is a small crew whose customers describe careful prep and asphalt that held up. If the job is the masonry, demolition or grading side, ask to see examples of that work before booking.
