Complex Windows

Great service. Michael installed a new window in my basement. He did a quick, clean and great job. Recommend!!!!

I would highly recommend Mike and his company. I’m so pleased with my patio doors and his professionalism. Mike and his colleague showed up on time, installed my beautiful patio doors and cleaned up all the garbage. He takes pride in his work and I highly recommend Mike and his company. You won’t be disappointed!

Briliant job done replacing my whole house of windows, great price and service with clean and efficient installation.

It was a pleasure to work with these guys. They do a very high quality job. I had 2 door inserts changed to the glass with internal blinds. And also had a balcony door with severe water damage replaced. They do a very neat job. They caulked and sealed up everything tight where i don't think a drop of water would ever get through. And everything was cleaned up afterwords. Great attention to detail and they don't try to cut corners. I would recommend this company.

Mike was very professional and accommodating from start to finish. He came in with great suggestions and was very transparent with his work quality and price. His job was done in a clean, timely and efficient manner. If anyone wants their windows and doors done to perfection then Mike is your guy! I'd recommend Mike to anyone that wants to install windows and doors with great service, quality and price!

We just purchased a new home and one of the things that needed to be done was the windows. Complex Windows was our 3rd quote, and we were very impressed. From the first day I started talking with Michael, he was extremely professional and made sure we knew everything there was to know about our purchase. The installation was quick, and very clean. We will definitely be recommending him to anyone that asks.

Michael and his team came to replace my back door. Very satisfied with the outcome. They were professional, quick, and did a great job. Would recommend!

Very good, professional, clean job was done in my house. We got explained what quality windows and door we are going to have. How they going to be installed. After some time we got a call if everything is good. We are very happy with the service and quality of the installed product
