We have been in our home for about a decade and the interlock in our driveway has been getting worse, year after year due to weather. WE did have someone relay the interlock but within a couple of years, it seems as it had never been done. WE are selling our home next year and the resealing done by Seal Tech has made all the differance. We chose a "wet" look and the driveway looks incredible. Their service was fast and efficient! I would recommend them!
