508 Sealcoating

508 Sealcoating is a driveway sealcoating business based in Natick, MA. Its website says it has been in business for 20 years and offers free estimates, and it lists a service area that includes Norfolk, Acton, Arlington, Ashland, Belmont, Brookline, Concord, Dedham, Framingham and Harvard. Nick is the owner, according to a 2026 review. A 2026 review describes a 2 by 5 gash in a driveway: Nicky and the team came out the same day, patched the hole and some other cracks across the driveway, and sealed the whole driveway. They also brought posts to block off both ends of the driveway so delivery drivers or guests wouldn't drive on it while it settled. In another 2026 review, 508 gave an estimate immediately with two options for materials, fit the job on a new small driveway in the same day, and got it done within an hour; both estimates were lower than what the first company that customer called was going to charge. In a separate 2026 review, Nick came out to evaluate the driveway, explained the sealing process and what work was needed to address the existing cracks, and followed up once the work was done with his thoughts on the end result and tips for caring for the driveway. In a 2020 review, a liquid-fertilizer stain was still on the driveway the day after the job, and he came over the next day and resprayed the driveway. In a 2019 review, Nick and his sons did a next-door neighbor's driveway the same day. A 2019 review describes sealcoating of a driveway and walkway, on time for a fair price. In a 2019 review, the price was higher than they were accustomed to, and there was a minimum price they didn't know about until they called about the quote; Nick also provided some slurry to a heavily cracked area that had not been part of the original quote.
