If you are looking for stained-type of concrete work for inside your house or a building, avoid these guys completely. Their prices are much, much higher than other companies. Their work is a disaster, unskilled and horrible. The grinding and preparation of the floors in my house was sloppy, uneven and was not ready for color. The stain type products they did use are highly toxic, the stain job looked awful, and amateur, and the sealant was peeling up within days. James disappears after the first visit. The workers couldn't fix the bad job because they didn't know how to do it in the first place. Since they don't know how to grind and prepare well, don't understand the chemical properties of the stains interactions with floors or the proper sealant choices for the floors, they couldn't fix them.
I had to completely redo my floors, including grinding and staining them, and they turned out terrific. Do yourself a favor and go elsewhere. Ask to see, in person, floors they have done before even considering using them. That will make it obvious.
