Mark has been in business a long time and I know why. From the very first consult about the new door, he presented thorough and knowledgeable information and advised us to take our time to choose the right door for our house. The door installation was completed today and I could not be any more thrilled. Looks great. I will recommend Mark's Windows and Doors to everybody.
Thank you for the very kind review. I have always believed in going the extra mile to make sure my clients have all the information. Enjoy your new door, It made a big improvement
Mark did some work for my sister in law and we were very impressed. Although we had a small job, Mark was quick to come give us a quote and educate us on his product. We then decided to have 2 more windows replaced. As soon as the pandemic allowed for renovations to continue, Mark was here to complete the job. Very professional. I would highly recommend Marks Windows and Doors.
Thanks you for allowing me into your home to make you as happy as your sister in-law. You can see a big difference in insert windows vs full frame . Your small windows don't feel so small as your glass space has increased by 6 inch's. I look forward to helping you on your future needs. Thanks again Mark
Mark is amazing. Very professional, works for perfection and is very efficient.
He makes sure he leaves no mess behind and the job is always 100% complete and to our satisfaction. We will continue to use him for all windows and doors that we need installed.
He recently installed a new sliding door to replace a DIY door that was done incorrectly 20 years ago.
We had booked him in the winter, but due to Covid19 there was a delay. During the delay Mark was always in contact with us on when he could get the install done and made sure we were comfortable with the time lines.
I will continue to recommend Mark to all my friends and family who need an install for windows and doors
Thank you guys for the continued support. Enjoy the new Sunview siding patio door for years to come.
We found Mark on Homestars. Could not be happier with the work Mark and his team did installing 3 new windows. I highly recommend Mark if you need your windows and/or doors replaced. We will be contacting him again for our patio door in a few months
Thanks Mark !!
You are doing such a nice job on fixing up your 1980 home. Changing the colour has really brought your home curb appeal up. We at Marks windows where glad to compliment the work your doing with our high standards. We look forward to working on your next project with you and you brother
Mark was referred to us by a family friend (he doesn't install in winter), and we were very impressed. Got 5 windows replaced and now getting a quote for the last 4 windows.
We at Marks windows and doors try to go above and beyond. Enjoy your new windows, I hope they have help cut down the sounds from the out doors. It sad that we sometime need to pull out older vinyl windows, but sometimes its not the windows but just a poor install, Like in your case. I Look forward to working with you in the spring.
Mark did an amazing job of replacing our entrance doors and windows. He worked with us to find options that fit our limited budget and did an excellent job of installing them in a timely manner. He is very punctual, and always accessible. You call Mark, you get Mark...not an answering machine. We are very happy with him and we have no reservations in recommending him.
We at Marks Windows are so happy that we could meet your budget. Thank you for giving us the chance to make your as happy as you are. We look forward to helping you in your need in the future. Thanks for the high review. Mark
Windows work well.
Nice clean installation.
Nice guy to do business with.
No issues whatsoever.
Would contact him again in a heartbeat.
Came in at price agreed on at the time agreed to.
Thank you Dennis. I am glad you are happy with your job. I knew you where worried about the stone work you had done before i arrived. As promised it was let un damage with a perfect fit. Thanks for the kind words and look forward to your future needs
My basement was poorly renovated and not even finished before the contractor took off!! I was in a pinch. I called Mark, and he came and not just finished the job, but completely re-installed the windows to meet proper basement safety standards. Now I know our windows will hold up through the fall rains and winter snow and cold. And I'm so relieved to know it was done right now!
There is nothing that bothers me more the contractors that don't keep their word. Thank you for putting trust in a contractor after being let in a poor state. I hope we where able to regain your trust in the trades. Thanks for the review and look forward to helping in the future.
We had Mark quote a bay window to replace an existing flat window. His quote was reasonable and we contracted him to install our new window. His installation was smooth and went as explained. All was very well installed and well cleaned up after.We were very pleased with the job, window and result and enjoy looking out of this window now.
Changing the flat window to a bay was a great choice. The curb appeal the new window has brought not to mention the feel in the room it was a great choice you made. Thank you again for the support of Marks Windows and look forward to helping in any more of you home needs
Before establishing Mark’s Windows & Doors in St. Catharines, ON, Mark started out working for a high-volume company in Markham, ON. As an apprentice to a window installer, Mark learned the importance of maintaining a standard of excellence at all times.
After several years, Mark bought a truck and some tools, and took on the role as the lead installer for the company. He then moved on to work for a large box store, where he saw the difference in the quality of products and services that were being offered to the lower-end side of the business. Mark has been doing this work for over 28 years.
Expanding His Skill Set
Mark’s creative nature prompted him to start designing and building decks. He has always put safety above everything because he cares about the well-being of his clients.
As Mark’s knowledge increased, so did his desire to become involved in the windows and doors business. He started working for an Anderson supplier where he had the opportunity to take on projects in high-end homes. Also, he became acquainted with the service and sales side of the windows and doors industry.
