Based on the great reviews, paid the extra money for what was supposed to be a "straighter, cleaner lines" and disappointed with the black sealer spilled on my stone work and the 'over runs' over the sidewalk, bottom of the driveway and up the visible part of the garage pad. Contacted Peter and he assured me he would be by on Monday to at least clean the stone work - no show , no call - called again Wed and he showed later that day, however i was unaware as there is still black staining on my stonework.
