I have had several people seal my driveway and after a few years I have settled on Barton seal coating. There are a lot of scammers with very poor quality material out there who will all tell you their product is great. I talked one of them down below what Barton charged me (but his initial quote was way above Barton's) and was sorely disappointed in the quality of the job. The texture, appearance and durability of Barton's sealcoat is far superior to everyone else's, and the initial quote beat everyone. I am calling them back this year to do my drive again.
