Reviews
Thank you John Galvao Home Improvement Service for the great home improvement you did for us. It was highly appreciated and I’m very amazed how professional you worked. It was all worth it. Keep it up!
John Galvao Home Improvement Service was very efficient; they were in and out in one day. I had them do the walk-in shower in the second bathroom. I researched the tile first, but it was much more time-consuming. This was all done in one day. I was very pleased.
