Pro Flooring

We decided to replace the oak hardwood floor in the living room, dining room, and kitchen. The floor had been glued to the concrete slab beneath. After the floor was removed, there was a residue of old glue on the slab and, it turned out, the slab itself was not level. A new hardwood floor could not be installed until the old glue was removed and the slab was leveled. We had the new wood, but could not proceed further
It is not easy to find contractors who do this type of work. The old glue has to removed by hand. Heavy duty sanding machines just become gummed up when this glue is sanded off. And few companies will level concrete slab if you do not purchase the flooring from them.
I found Pro Flooring through HomeAdvisor.com.
To my relief, Vitally @ Pro Flooring was willing to do this difficult job, and his estimate was reasonable. Another company asked for more money and would not do the job for at least two months.
In the end, Vitally and his crew did an excellent job. They stripped off the old glue, primed the floor, and put down self-leveling compound. Because the slab was so uneven, a second application was required. When Vitally finished the work, the slab was clean and perfectly level.
Compared to the difficulty of removing the old glue and leveling this concrete slab,
installing a  hardwood floor, or refinishing an existing floor, would be a piece of cake.
 
Vitally is from the Ukraine. His English is good, but it is his second language. For this reason, he may not seem to be highly articulate. Don't be put off. He does the work promptly; he is fair and honest, and he is experienced and competent. He also happens to be a very pleasant person. 
Having purchased expensive hardwood flooring from a local retailer, we did not anticipate encountering this difficult problem with the existing slab. Without Vitally's skill and availability to do the job, we would have been unable to move forward.
