He’s professional, patient, and responsible person.Always respond to messages  and ready answers all your questions and concerns about installation proces cleaning or finances.
He’s crew is team of great , hard working guys. Always on time ,respectful , kind, helpful with any questions or concerns you have during the whole project. Every evening they make sure property it’s clean ,material secured and protected from weather.
Demo work, cleaning, water proofing, prep work of doors and windows, flashing, insulation or siding installation - just perfect. Windows and doors aluminum finish trims - just beautiful masterpiece work.They also install fixtures , exhaust vents accessories, new gutters and split AC system condensing pipes covers with looks great.

The best in the business. Everyone that goes past my house when I’m outside compliments it. Changes mid project were easy and Rey was super accommodating. I’d only recommend NISI for exterior projects. Clean, respectful, hard working crew. Nobody can compare to these guys!...

Nisi Home improvement is fantastic! Rey helps every step of the way, is knowledgeable, and answers every question you have explaining in detail so the homeowner feels comfortable! My roof looks FANTASTIC and work was done efficiently and carefully! I can’t recommend Rey and the Nisi team more!...

I found NISI through Google Maps, searching for contractors who were nearby. They had good reviews. When Rey came to talk to us we liked him right away and did not even bother getting any other estimates. He was very patient in explaining everything and gave us very good advice on all the details of the job. We felt that the price was fair and Rey was very patient with us as we made minor changes along the way.  He even had his crew work on a Sunday because we made a change that was going to require more time.The crew was hard-working and efficient, cleaning up every day before they left. I can’t find a single flaw in the work that they did. I recommend NISI highly....
