Concrete Resurfacing Products, Inc.
I would never recommend Mike Dussling or his company for anything. We contracted with Concrete Resurfacing for an acid stain finish to our porch floor what we got was a giant mess. The end result after two attempts looks like paint was spilled and half way wiped up with rags. We have to hire another company that knows what they are doing to come out grind the mess that Concrete Reurfacing made off the floor and start completely over. Jenny in the office and the sales person Roger were nice enough to deal with but the owner Mike is a jerk who couldn't be bothered to call us or come out to see the floor until I said that we would not pay him the balance for this fiasco. There are many quality companies out there that know what they are doing when it comes to concrete finishes, this company is not one stay away and never hire them.
