They cleaned up all debris each day before leaving. We are beyond pleased with the results and are looking forward to a more energy efficient house this winter.Robert Kleinman2024-09-20If you’re looking for a certified roofing professional company, NISI Home Improvement is the company you should use. I interviewed six roofers. I was about to call the one I thought was best for the job, but then I received a text at the last minute from a friend praising the roof work of Mr. Marvin, who is one of the owners of the company. I called Mr. Marvin, explained that I was having a leak coming from the entrance of the house and I wanted my roof replaced. Mr. Marvin and his son, Nelson came out the next day to look at my roof. Mr. Marvin went up on the roof to see what needed to be done and explained to me, in detail, that the price they quoted me for a new roof may change once they removed the shingles, depending on the condition of the wood underneath. Nelson also explained the process of installing my roof from beginning to end. Two weeks later, the crew showed up and started working immediately. Everyone was professional, friendly and hardworking. Nelson was always onsite and if he had to make a run for more materials, he had Alex who was second in charge, stand in until he returned. Nelson and Alex were always available to answer my questions. It took his crew two days to finish the roof. From the first day the crew started working on my roof, I felt very confident in their ability to get the job done and they did. I would like to thank the crew for the great work they did; Alex, Jimmy, Robin, Enrique, Gamaliel, Willmur and strong man Chon. Mr. Marvin and Nelson, thank you for my beautiful roof. The job was well done and the work quality is excellent. Nelson, you were an exceptional communicator throughout the project. You kept your word and due to the condition of the wood, lowered the quoted price. I truly appreciate your honesty. I will definitely refer you to family and friends.Gillian Gamory2024-09-16Marvin is very knowledgable and very quick in responding to my call. I found a leak after a huge rainstorm and I called him that same day, and lo-and-behold, he was available to check out the roof on the same day. Not only was he thorough with his assessment, he actually helped me understand the underlying cause of the leak rather than fix, patch and go. He answered all my questions, gave me two quotes and potential scenarios. His team was efficient and amazing and my family and I are very very happy and satisfied with his work!Maggie Yu2024-09-07We highly recommend Marvin and Nelson from Nisi Home Improvements Inc. for their professionalism, attention to detail and ability to actively listen to our concerns.

This work was done on my new house so this time they also installed a beautiful bay window as well. Working with Marvin and Nelson, father and son, is such a pleasure. Very professional, from the estimate all the way to the clean up.Tom Fearon2024-08-02
