Ion did a wonderful job on our bathroom. He completely removed the entire existing bathroom back to the joists and rebuilt a beautiful shower room. I found him to be honest, trustworthy, hardworking and reasonably priced. I couldn’t recommend him higher.

We are very pleased with the work that was done. There was a quick response to the job that day via a telephone call. An appointment was scheduled for a couple of days later and the work was started early that day & completed that same day. The workers were on time, polite, knowledgeable and proficient. They promised to make a visit a week later to remove the supportive structure and did exactly so yesterday. I am very pleased with the work and their professionalism.. i highly recommend them.
