Michael was very responsive in preparing a quote and processing my order. The workmanship was superb. The window color was a excellent match to my stucco exterior.
I would definitely use his company again for other windows in my house.

Michael was very professional and creative. He was able to design rounded vinyl windows for out townhouse and match the colours. His work was done well and for a very reasonable price. Highly recommended!

Mike and his team did a great job replacing all windows and Patio door in my house. The crew showed up on time, did the installation work with professionalism and care, cleaned up everything and left behind a family of happy customers. All windows look great and we can feel the immediate impact ability to insulate the heat from outside. I also got the patio doors with mini blinds inside, and they are just great.

My overall experience with Mike has been great, he is highly responsive, knowledgeable, and handles the installations personally. Products are high quality and are of great value. Highly recommend Mike and his company Complex Windows & Doors.

Thank you once again Mike.

I couldn’t be happier with the professionalism, workmanship and friendly service! My neighbour and I both had our windows replaced by Complex Window and I am so pleased that we chose Mike and his team. From the initial discussions to coming onsite for the measurements to the final install, Mike and team took the time to answer all my questions and provide me with all the required information until I was comfortable. Their service is outstanding, they showed up on time and didn’t rush to get the job done. They take great pride in their work and even when they were done with my house, when they started my neighbour’s house, they made sure to stop by and ask me if everything was ok and whether there was anything else I needed or whether they could answer any questions.

When I was getting quotes from other (bigger) companies, I was highly underwhelmed by their lack of customer service particularly when these other companies expected me to do all the measurements for them just to get a quote! Mike was happy to come to my home and do the measurements, introduce his company and share his service philosophy; and that type of personal touch certainly goes a long way! I will definitely be recommending Mike and Complex Windows to my family and friends!

Well done Mike! Thank you.

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.
