Best Window Companies in Guelph

My experience with Greg and Hartmann Windows and Doors was excellent. Very polite, timely emails, making sure that "we" the customer are happy with what we want, giving us other options in case we didn't think about it or finding out the answers to our questions when he didn't know himself. We had a custom pivot door installed, and it looks and is exactly what we dreamed and expected. During the installation, they cleaned up after themselves, made sure the window in the door was clean. Even after the instillation was done, Greg came back for some small adjustments.

We can't say enough about our experience with Greg and his team. Greg was prompt to contact me when I requested a quote and his expertise really helped with our decision making. He took us to see doors he had completed on a couple of occasions. Seeing them in person helped tremendously. He knew our vision and we are very happy with the results. No hesitation when he needed to return to fix a small issue. We highly recommend!

Greg was phenomenal, went above and beyond for installing a new door and multiple windows. Strongly recommend.

This company is fantastic. Their staff are very friendly and helpful. We had very specific measurements for a new egress window and they came and measured multiple times to ensure it was correct and would meet the requirements. Can't recommend them enough!

I can’t say enough about the quality of service and amazing product installed by the George’s team. On the day of the install, they were professional, efficient and had great attention to detail. Their work definitely improved the curb appeal of our house tremendously. I would 100% recommend this company for all your windows and doors needs!

Dave is very clear about the plan, does excellent work, and is easy to get along with in organizing and executing the project.
