"When he arrived to my home, the technician, Sean, assessed the problem and provided a simple solution not only for the present but for the future as well. He answered my questions and completed the project timely. My peace of mind was restored. He said to give a call if a problem should arise. I don't expect a problem but it is good to know that someone is there to help if it should happen. Thank you."

"Internet connection was weak, garbled communication. But, they remained very professional and we could crack a joke every now and then when things got annoying. Once up and running the diagnostic test was done in 5 min. Confirming my suspicions. Part number was sent within minutes."

"Time efficient with getting the job done and I appreciated the explanations and help to figure out the best solution to my problem when it came to the water in my basement. Did not feel like they were just trying to get the job that made them the most money, but the best solution to my problem."

"Highly, highly recommend. Their work exceeded our expectations. They were timely in responding to our questions, communicated with us at each step of the way, cleaned up the mess they made where others left it behind, helped us to discover and repair water damage the contractor ignored and, in the end, made our 3 bathrooms look both inviting and elegant. WOW. Andrew and his team stand apart in the quality and professionalism of their work, all at an affordable and reasonable price. Wish I had another project for them, they were that good!"

"Everything went great. I showed Robby a picture of what I wanted and that’s what we got. The project took a bit longer than we thought but the final product is excellent. I would definitely hire them again and recommend them if your looking for a bathroom remodel."
