"Windows are good. Work was sloppy. Still finding shards of glass on the floor and the furniture a week after completion. Caulking looks like a third grader did it- including caulking the screen door to the frame. For this type of investment, they should act like professionals."

"This is the second bathroom that I’ve had Miguel and his team come out to install the glass shower door. They were very professional throughout the process and the price was very reasonable. Great service just like they were with my first bathroom project 7 years ago! Thanks for the great work. Highly recommend Installers DMV"
