Get matched with top window pros in Greenwich, NY

"They installed windows for us. We found one window that was barely cracked. They came right back out and replaced it right away. The windows are very high quality and they are easy to clean. It so nice to have the new windows!"

"We replaced the windows in our 1933 home through the services of MadCity Windows. From the initial contact with their sales representative to final installation, the company provided top notch professional work. With the draft from the old windows and the cold of the glass, we are already saving on our energy bills. Our house had old, large windows, so they had to be custom made. As an industrial designer and interior designer, we find our windows to be of excellent quality."

"Tom and Anderson did an outstanding job installing my windows and answering my questions. I would recommend them to anyone needing to replace/ install new windows."

"Crew was professional, courteous and extremely skilled. Clean up was done every day. Windows are excellent qualityâ"

"I hired Steve to help me install 4 windows at my house in Lake Luzerne. Steve reached out to me immediately after the inquiry and we discussed the project in detail. Within a day or two he stopped by the house to look at the scope of the project. The price quote was excellent, we hired him. He was a pleasure to work with and had great communication skills . The window installation was completed and it looks great. I asked Steve if he could help me again this weekend, he is scheduled to come back Saturday morning. Nice, honest, respectful person. I would highly recommend him for any of your household projects. 👍. Below are the 4 finished exterior walls. The other are before and after pictures. Pine T & G is going up this weekend."

"Quick and prompt. Thank you!"

"Wood flooring and so much more. Carpets torn out, subfloors repaired, including work at doors and windows. Impeccable attention to detail. No threshholds, smooth perfect and tight seams from room to room and door to door. I love a crew that doesn't have to hide their transitions under a threshhold. Work ethic--- amazing, here on time, every time, every day. Added on recessed ceiling lighting in 2 rooms and ceiling lights in all rooms. Brutal attic work on over 100 degree day. Seamless experience in every way. They clean up the site at the end of every work day. They haul away whatever needs hauled away. They are friendly, talented, welcome input and do what needs to be done to exceed all expectations. (there were none!). I have more jobs scheduled: decking (including relocating propane tanks), house addition, complete renovation of two bathrooms., fencing. My go to crew for everything."

"Scott was absolutely terrific. Fantastic communication before, during, and after. I knew exactly when he would come, he communicated with me while I was in the hardware store about what materials and supplies I was getting, and he communicated well on any needed follow-up. He corrected some tricky wiring and installation of two ceiling fans. He replaced old screens and built some new screens for many windows, replaced screen material and added pet-proof protective hardware cloth for screen doors, and he and his family laid a series of slate stepping stones and did a terrific job laying them flat on a sloped and curving surface. He worked on faucets and installed a driveway sign. There seems be nothing that Scott couldn’t do, fix, or diagnose. I was so pleased that I got to work with him and I look forward to working with him in the future."

"I used Window World for my window project. They replaced 8 windows in 2 hours at a fantastic price. Very happy with the results."
