Boston Alliance Roofing and Seal Coating seals and patches driveways. On one 2026 job, Joe and his father sealed and patched a driveway; they took their time, were meticulous with every part of the job, and didn't leave until everything was just right. On another 2026 job, they gave a quote and did the work 2 days later, cleaning the driveway and putting down 2 coats of sealant in about an hour and 15 minutes, and Chris was friendly and professional. In a separate 2026 job, Joe put two coats of the sealant material on a driveway, explained all the options and how the work would be done, and explained how long to wait to walk on it and to put cars on it. The crew prepared a driveway for both crack sealing and a double coat of sealant on a 2026 job, with the foreman, Joe, ensuring that things were done right, and they also had the best price. Another 2026 job came with a good quote and a senior discount, and the work was done in record time. Not every job went smoothly. On a 2026 driveway, the seal coat came out well but the asphalt patches did not sit flush with the existing driveway: one patch in the middle resembled a speed bump, the large patch at the end was not smooth, and the transition from the driveway into the grass along the edge was very uneven. On another 2026 job, a lot of cracks were left unfilled, and after 3 payment options were offered and a check was already made out, there was a push to pay with cash. A 2026 two-coat sealer job left visible brush strokes where the second coat did not overlap the brushed edges, and a complete top coat application at no additional cost was requested.
the job was done quickly as i was told. i was told of 3 payment options and my girlfriend was kind of being pushed into trying to pay with cash after i already made the check out. if you only want cash then just tell people that. a lot of cracks were left unfilled and i wasn't expecting that. i won't be in a rush to call them back.
Absolutely outstanding work by Joe and his father! They did an amazing job sealing and patching our driveway, and the attention to detail and commitment to perfection really stood out. They took their time, were meticulous with every part of the job, and didn’t leave until everything was just right. It’s clear they take great pride in their work and truly care about delivering a quality result. Highly professional, hardworking, and dependable. If you’re looking for someone who cares about doing the job right—not just getting the job done—I highly recommend Joe and his father! ⭐️⭐️⭐️⭐️⭐️
