"Roger is a gentleman and a professional of the highest caliber. My wife and I are building a home in North Stonington, CT and hired a virtual architect 2 years ago to design our home. After $5,000, and 3 months, we were left with what felt like an intern-level deliverable. We swore that the next time we used professional services, we would find someone who had experience in the industry, knowledge of the area, and the passion for building a young families dream home, not just processing work. We found all of those things in Roger and could not be happier with his work or his kindness as a person. I am now in the budgeting phase and am sending out Rogers drawings for contractors to quote, and the first thing every one of them says is I have not heard of this Greenwald guy but he does damn good work. It inspires my wife and I to know that we were in such capable hands."

"Sentri Homes provided the most professional flooring service I’ve ever had. The LVP installation turned out absolutely beautiful, and I was amazed at how quickly everything was completed without sacrificing quality. The crew was fast, accurate, and extremely detail-oriented from start to finish. Everything was installed cleanly, precisely, and with real craftsmanship. The entire process was smooth, efficient, and far beyond what I expected. I would absolutely recommend Sentri Homes to anyone needing flooring installed."

"Two full gut jobs on bathrooms. They came out great. On schedule even with weather delays. Even came back to fix something that was faulty from the store, not their work. I recommend their work and would hire again for my own home."
