6+ Room New Window Service
$43,000
Oz is someone who really cares about the quality of the work being done. He has lots of experience with home renovations and understands both the construction side and the customer side of the business. He’s professional, easy to communicate with, and does what he says he going to do and keeps to the schedule. That kind of reliability goes a long way, especially with home projects. We replaced all of our windows after we bought our house and we love the new windows! I’d absolutely recommend CT Window Replacement to anyone looking for new windows!

I’ve known Oz for years through real estate and renovation work, and he’s someone who really knows what he’s doing. He’s been involved in projects for a long time and understands quality construction and what actually holds up over time. More importantly, he operates with a lot of integrity. He’s not going to cut corners or recommend something just to make a sale, he genuinely wants things done the right way. I have trusted him with my own home without hesitation.

He’s always been reliable, knowledgeable, and easy to work with. One thing I really respect is his integrity. He’s straightforward, communicates well, and genuinely wants things done the right way instead of taking shortcuts. With his experience renovating homes and managing properties, he has a strong understanding of quality workmanship and what homeowners actually need. I’d definitely recommend him to anyone considering window replacement work.
