"Everything went really well considering we were not planning to replace flooring in the kitchen or installing a new sliding glass door. Our initial intent was to replace/fix the grout in the kitchen that was cracking and coming up. However upon further review it was discovered that the tile had not been appropriately laid initially. When removing the tile from the kitchen we found that our sliding glass door had been leaking and there was damage to our floor and the door needed to be replaced. Very happy with the results overall.
