Recently completed master and guest bathroom remodeling and very happy we chose QA Builders. Sal was very informative about our design options and set up meetings with his vendors for tile, hardware, and fixtures. This gave me the knowledge to select all the materials with a budget I was very pleased with in the end.

His team was very professional, meticulous and hard-working. They completed on schedule and at the price quoted, which we felt was a very fair cost and reasonable timeframe. Permits and inspections were handled very efficiently.

They also did reflooring of our half-bath and retiled our fireplace.

We would work with Sal again for the many projects on our list!
