Windows

I had 4 basement windows installed yesterday. The job was done in a timely and efficient manner. All debris was cleaned up. Mark and helper were pleasant, polite and helpful. Mark took the time to answer all my questions, even the ones not pertaining to this particular job. I would not hesitate to call this company for any window work I may need done again. Thank you, Mark.

Replacement of front door on house

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.

Very happy!

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

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 !!

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.

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.
