Wellhouse installed flooring for multiple homes in my area. More than not had significant problems, some requiring whole floors to be ripped out and redone. On our floors, they did not meet manufacturer specifications for making floors level. Ridges with >1/4" clearance under level, with tolerance at no more than 1/8" per 10 feet. They did not follow manufacturer's requirements for an absolutely smooth surface, did not follow manufacturer's instructions for materials to use under floor. Originally denied their company sealed the gypcrete beneath, which would mean all the glue holding down the tiles would come up. Later then claimed to have done it. The floor is a soft tile, and shows ripples and bulges, which mar the beauty of the materials. The floor was $10.50 a square foot. They were required to seal the surface with 4 coats of urethane. They somehow missed a 6" x 1" strip in a doorway. I am doubtful that the same 6 inch strip in a traffic area was missed 4 times, and suspect they did not seal floors according to manufacturer requirements. Their installation has voided the company warantee on the materials. The rep from company that made the tile reviewed photos of the floor, and called it "unprofessional" and said that it should be replaced by "a qualified installer." Flooring installations in the majority of other houses I know they worked on had significant defects, including wrong size & color of tile. Whole floors had to be ripped up and redone. Their "fixes" for problems were worse than the problem, often. Debris was tiled over, despite manufacturer instructions to vacuum floor before laying the tiles. Their "solution" was to whack the places with debris with a mallet, reasoning it would smash the debris into the gypcrete. The tile is a soft, bendable material. It is a no-brainer that whacking a soft thing on top of a hard thing would of course damage the back side of the tile. They have agreed to replace some of the flooring, but not all. We are in negotiations now, and have chosen another type of flooring that is more "idiot proof." I have been told that instead of removing the baseboards to allow the 1/4" needed for a floating floor, they will just go up to the baseboards, then slap a quarter round on top of it. When thicker floors transitioned to thinner floors, they did not meet the ADA requirements. Some had an edge about 1" high, which would not allow ease of use for walkers are wheelchairs. Footprints were tracked from the sealed floor, across the ceramic tile. The ceramic tile is the wrong color.
