Avoid them at all costs. We have had a horrible experience. First we had to wait because they refused to do our driveway before our road was done stating the edge of the driveway would be affected, second once it was done the rough stone was showing on top so Rohner came out to seal it, in two phases, which left a thick tar stripe down a portion of our driveway, third within months low spots and humps started to form and we had stones popping out leaving a ton of 1/2-1 inch holes in our brand new driveway. Rohner never shows up when they say, only looks at stuff when owners are not around and claims to see nothing wrong, promised to reseal our driveway again last year and never called back. Tried calling again this year to schedule early spring and no response - finally filed a BBB complaint. I can go on and on about how difficult it is to deal with this company. read more
