Sliding door install

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

WINDOWS REPLACED

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

Windows

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.

Windows and Doors replacement

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.

Fixed my reno from hell!

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.

bay window

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

Storm door

I met Mark while shopping for a storm door and asked his advice. Mark was very knowledgeable so I asked for his business card. After researching the comments about his company I called and set up a quote. It has been a pleasure, he was courteous easy to talk to, very knowledgeable and on time. The job he did is first rate for sure, even taking the time to repair my neighbors door ( at no charge )what a great guy recommended by me for sure. Thanks again Mark and Will
