Dori and his team were great from the first conversation I had with him on the phone. Very patient, understanding and fast to come to my house for a free quote. Out of the 4 companies who stopped by, Genis Construction are who I went with.From the time of the quote, waiting for HOA approval of the job (which Dori wrote up an excellent description of exactly what was to be done and materials used), to completion of the immediate work was less than 3 weeks. Most of the wait was delay by our HOA.All of this was in light of finding a lot of rot during our deck remedy job. Dori instantly called once he uncovered the problem and proposed several solutions. For peace of mind we requested the most complete, and most expensive, option. Dori was very understanding with the change in timeline, workforce needed, and cost/payment.Fast forward those 3 weeks and we could not be happier! The deck feels solid and looks beautiful! We can only hope when were ready for the next project that Genis Construction, and Dori, will take on our headache of a home.

Thank you so much for the kind words and for trusting me and the Genis Construction team with your deck project. It was truly a pleasure working with you.
I really appreciate your patience and understanding, especially when we discovered the unexpected rot and had to make some changes along the way. I’m very happy to hear that you’re pleased with the final result and that the deck feels solid and looks beautiful.
Thank you again for choosing Genis Construction. I'd be more than happy to help you with your next project whenever you’re ready!

My brother recommended Dori to me when I needed my deck fixed. Really happy he did, Dori was great to work with and did a very good job. He showed up when he said he would and you can tell he actually cares about his work. Deck looks great now and everything was done properly. Really nice guy too.
