Concrete coatings in Ann Arbor, Michigan
Ann Arbor garages, basements and patios, finished in one day
From older homes near the University of Michigan campus to newer subdivisions out toward Dexter, Chelsea and Brighton, Ann Arbor-area homeowners want a floor that looks finished and stays that way. Plenty of basements here are being turned into living space, and a coated slab is the fastest way to make one feel like part of the house.
Midwest winters are hard on concrete. Road salt and melting snow work into the pores of an uncoated slab, freeze, expand and slowly break the surface apart, and summer humidity brings musty basements and sweating floors. A fully sealed polyurea and polyaspartic system stops salt and moisture at the surface, so the floor wipes clean instead of spalling.

If you are on the fence about getting your patio flooring poly coated, you should contact Comer and Cross!!! Not only is the finished work beyond beautiful, the customer service is just amazing!!! We were supposed to get it done a few weeks ago but Mother Nature had other plans. The communication that Moe (crew leader) had with me was so professional and beyond accommodating. He was even going to come on his day off (Sunday) two weeks in a row to get it done. Moe and Damian came today and I knew it was gonna look good, but I am blown away how amazing it looks!!! The two of them worked in the 95-degree heat and were so efficient and super friendly!!! I'm so excited to begin using our patio. If we do our garage floor I would only go with them.

Very professional and knowledgeable from start to finish. Used them to coat our garage, which they did a great job on. They may be a little more than some other companies, but they certainly do a great job and great attention to detail. We got quotes from other companies that were higher and they did not seem to be as knowledgeable or do as good a job as Comer. Would recommend again for any service they provide.

We had 2 projects done: our basement and our garage. Looking back on my before pictures, our garage was pretty bad. We had rust-pitted concrete from the salt and weather. Now they look amazing.
