Had a great experience with David. He was easy to work with, and most importantly for me, able to squeeze the job in the following week. My refinishedhardwoodfloors look amazing. Little dust here and there but I expect that’s normal. Extra appreciated that he was able to complete my floors leaving the baseboards on and undamaged. He even came back at no cost to touch up a spot I’d scuffed after the coating had cured. Good stuff, recommended.

David installed LVP (luxury vinyl plank) in two bedrooms end Oct ‘22. I was initially undecided about refinish vs new floor. One bedroom had an antechamber/study with an irregular long threshold to bedroom proper and closet. He was able to find a supplier for the right color/texture we needed and scheduled the job on short notice. The result looks great, including threshold. He quoted me a price much less than other two bids and he seemed way more knowledgeable about flooring work. Good attention to detail and cleaned up everything post install. I Would use him again and recommend him.

I’d give David more than a five star if I could. The process was efficient reliability and smooth as can be. Thank you for a wonderful full service flooring experience. My family and I knew that we were interested in getting new wood floors and it was time to be honest. David was wonderfully informative and after talking He came out to measure and provide an estimate and we came up with the perfect floor for us. Always showed up on time, respectful always remembering he’s working in someone’s home and was careful with my very curious dog. The quality of the instillation is excellent! Thank you again for a smooth, timely transition to beautiful new wood floors!

David did an outstanding job on our floors. From the estimate through to finished construction, everything went smoothly and was as promised. David has continued to check in with us to see how the floors are performing. Great job!
