Mark’s Windows & Doors reviews (51)

Mark and Will did a fantastic job installing our windows and doors. Mark's knowledge and expertise encouraged us to select a front window for our home that we might not have picked on our own. The results were amazing and increased the air flow and view out of our front window dramatically. We have also had very nice compliments on the look of the new windows and doors from our neighbours, friends and family. Mark's ETA as to when the windows and doors would arrive for installation was very reasonable and accurate. Mark and Will showed up on time on the days they said they would be here. They patiently answered any questions we had during installation and never made us feel like we were burdening them. They have great knowledge and talent and were very reasonably priced. We appreciate everything they have done for us and love our new windows and doors. We definitely recommend them to others. Thanks again Mark and Will

Mark and assistant arrived on time, completed their work efficiently and cleaned up so well that you would never know that they had been there at all. Extremely satisfied with their work. Dee loves her new Red front door that much we got the whole house painted!! Thank you so very much Mark for a job well done! Larry & Dee Welland

Mark arrived at the scheduled time, effortlessly installed my door and I am very happy with it!

We are so fortunate to have found Mark to do our Sunroom. We can’t say enough about the excellent service and quality of the project, from the quote (right on budget), timelines (start & completion) quality of products & especially the accuracy and quality of workmanship there was no guesswork. They arrived on time and worked non stop Mark is EXTREMELY knowledgeable and PROFESSIONAL. In the overall project he gave us several ideas, from the configuration of the windows and door, Mark looked at our home and matched the existing material which made it look like it was built with the home. We can’t say enough about how professional, knowledgeable & hardworking they were. This is how a business should be run. Thanks so much for all your hard work, care & knowledge Mark we LOVE our Sunroom & we have had SO many compliments!

I have used Mark for a few window replacement projects in my house. He is quick to respond, shows up when he says he will, and is a generally very pleasant person. He is knowledgeable about his products and will provide recommendations if asked. I have recommended Mark to others and will continue to do so.

Mark and Will did a fantastic job installing my new windows.They were very professional and quick you can tell they have been doing this for a long time. I would definitely recommend them to anyone looking for new windows

Amazing work again ! This is the 3rd time we have called on Mark for an installation. This install was done to perfection as always. 3 front windows and a side exterior door were completed and we could not be happier. We will call on Mark for any future work to our house. I would not hesitate to recommend him to all of my friends and family and to anyone looking at this website. Mark is in a league of his own !! Thanks again !!!!

Mark is a true professional contractor. He arrived to complete the job when he said he would. He removed and replaced an exterior door. The fit and finish was excellent. The interior and exterior was left clean. I would highly recommend Mark.

I had a basement bedroom window installed by Mark. He was very knowledgeable and friendly. He arrived when he said he would and cleaned up after the window was installed. I love my new window. Thanks mark!

Over the winter a very large window - close to a skylight - was leaking very badly. Mark and his team had to order a custom sized window. they were able to retain the trim (which is apparently unique and close to 150 yrs old). they were efficient; made no mess...and I recommend them unreservedly.
