In the fall of 2025 we had Northshore Windows and Doors replace our back door and patio door entrance to our 1970’s home. Jason and Brenda were great to deal with and kept in touch throughout the project. During the install the crew discovered a structure issue with the patio door and they worked very quickly and professionally to address the situation so that the door was able to be installed. The work was completed on time and the job site was kept neat and organized.. thanks again for making what could have been a very stressful situation easier to handle. We highly recommend Jason, Brenda and their crew.

From the first day of contacting Brenda,then meeting Jason for a quote. Very professional, knowledgeable and so helpful picking out the products I needed for my project. Planning went seamlessly and on game day I met the whole crew. Jason, Brenda, Chris and Liam were the most efficient crew i ever had the pleasure to witness. Outstanding products. Outstanding workmanship. Again I thank you guys so much and I hope I can work with you again. Don't look anywhere else for windows and doors. Northshore if I could give you 10 stars it would be there. Cheers 🍻

What a great company! Great pricing! Jason and his crew were professional, pleasant, polite and always willing to help in any way. I didn’t have the time to take down some of our window coverings and they did that for me. Jason was willing to work around our schedules for installation of 8 new windows. They worked quietly, quickly and responsibly, leaving our house cleaned up and back to normal in no time. I will definitely use them again, when the occasion arises. I highly recommend them!

This is the second time we requested work from North Shore Construction. We had a patio door and window install when we first bought the house in 2016. We like the work and professionalism so much, we went back for more windows (3) and front and back doors. Really happy with the result, the professionalism of the team, efficient, friendly and courteous people. I recommend them whole heartedly. I was impressed with the fact that they sweep, vacuum and washed all windows and doors afterward. We will be back with them for more work in the near future for sure. Three time is the charm 😊

If you’re looking for an honest, professional and high quality window and door installation contractor then consider your search over. The work done by Jason and his team at North Shore Construction Windows and Doors is a direct reflection of the 5-Star rating they continue to uphold with every job. When contacted for a quote, Jason showed up the same day to measure out 15 windows I was looking to have replaced. He was friendly, knowledgeable and most importantly frank when it came to what work really needed to be done and where costs could be saved. After receiving a few quotes it was clear that Jason’s was both competitive and provided the best life-time warranty package, a testament to their expert workmanship and quality product guarantee. What was scheduled to be a two-day job, ended up only taking Chris, Allan and Liam 7-8 hours to complete to the highest standard. Jason also showed up later that morning to assist with the installation and oversee the workmanship (I think he really just wanted to be credited for the awesome work the crew did – Jokes!). The team were professional, worked well together, cleaned up after themselves and were polite throughout. I have nothing but positive remarks for the work they did and could not be happier with the finished product! Look forward to using Jason and North Shore Construction Windows and Doors for any/all future projects I have.

Before you hire a window and door installer in Ontario

No provincial licence is required. Installation quality is governed by manufacturer specification and the Ontario Building Code rather than by a trade certificate.

General liability insurance and WSIB clearance

Standard checks. Window installation involves ladder work and heavy glass.

Manufacturer-trained installer status

Matters more than usual here, because most window warranties are voided by installation that departs from the manufacturer specification.

Building permit for new or enlarged openings

Replacing a window in an existing opening generally does not need one. Cutting a new opening, or enlarging one for a basement egress window, generally does.

Verify with: Your municipal building department confirms what your specific job requires.

ENERGY STAR certification for the product

Relevant if you intend to claim any efficiency rebate, which typically requires certified products and documentation.

Questions worth asking

  • Is this a retrofit or a full-frame installation? What would the other one cost?
  • How is the gap between the window and the rough opening insulated and air-sealed?
  • Is exterior capping included, and in what colour and material?
  • Is the warranty on the glass seal, the frame, and the labour - and are they different lengths?
  • Is the warranty transferable if I sell the house?
