Services
We recently purchased a front door for our house. We consulted with Greg first to see what advice he would offer. Greg was very sincere and gave us suggestions on the type of style and make of doors would be best for us. We even got to pick a specific colour for our door. Greg and his co-worker came and installed the door, cleaned everything up and left the place looking neat and very lovely.
If your home is not keeping you warm in the winter and cool in the summer, or if it feels drafty when you stand near your windows or patio doors, it may be time to replace your windows in Guelph. Older windows and doors may allow air to escape resulting in your HVAC system needing to work harder to keep cooled or heated air inside your home.

We have had the pleasure of working with Greg over 28 years. He has installed all the doors and windows in our house, through our various renovations. In all that time he has demonstrated the same high attention to detail, timely response to our requests and dogged determination to ensure the product meets our needs and expectations before any job was considered to be complete. We have no reservations in recommending his services.

Hi Greg.
Just want to let you know our that our doors, windows & railing, especially the entry door, were a big hit with the painters we had in tonight to give us an estimate. Early on they asked who we got them from and of course we told them. When they were leaving they asked for your information as they wanted to have it on hand for any clients that might ask for a recommendation. I was able to provide them with your business card.
I realize your busy but hope the referrals from The Painter Sister brings you even more clients.
Thanks again.

From the initial consultation to the finished product Greg and Hartmann Windows & Doors were professional and a pleasure to work with. They provided a great product, very good ideas and delivered to us earlier then promised. The installation was perfect and they left our house spotless! They are amazing! I would highly recommend and we will use them again!

We are so very pleased with our new stylish door! It was a pleasure to work with Greg throughout the process. His quote was quite competitive with other companies, but his prompt responses, great ideas and quality product; put him above the others. Greg and Drew did an awesome job removing the old door and installing the new one with no issues and no mess. We would not hesitate to highly recommend Greg. Thanks so much Greg!

Greg did an excellent job. This was a storm door custom fitting which was complex. The work was carried out professionally and competently, on time and within budget. Would highly recommend Greg.

Greg has been a customer of mine for a very long time. Over the years dealing together, Greg has been one of the most professional Dealer's I've ever worked with. Greg has spent many years developing skills in sales and installation that have led to satisfied clients and gorgeous work.
Our relationship has grown over the years as well. Today I find my relationship with Greg to be one of growth and open communication. We learn from each other and have the ability to better ourselves and our businesses because of it.
Congratulations Greg! It is rare that a business is built on such a strong foundation
