Complete Window and Door Replacement Project in Mississauga, Ontario

This Mississauga project started with a few replacement windows and later expanded into a full window and door replacement after the homeowner felt a major difference in comfort, drafts, and humidity control through the winter.

Project Overview

NorthShield completed a window and door replacement project in Mississauga for a home built in 1990. The homeowner originally contacted NorthShield to replace a couple of windows, then called again after winter to replace the remaining windows and doors.

After living with the first NorthShield windows through the colder season, the customer noticed a major difference compared with the older windows in the rest of the house. The upgraded units helped reduce humidity, drafts, and discomfort, which gave the homeowner confidence to continue the project.

Existing Window Problems

The homeowner had purchased the house three years earlier, and the existing windows had been replaced by the previous owner roughly 15 years before. Even though they were not original to the home, they had serious performance issues.

The main concerns were drafts, humidity on the glass, and moisture around the framing. When the old windows were removed, NorthShield could see that the previous installation had not been insulated properly around the frames, which explained why so much air was moving between the window and the opening.

Our Solution

NorthShield recommended a brick-to-brick replacement method with high-performance triple glass windows for maximum efficiency. This allowed the installation team to remove the old units fully, address the poorly insulated openings, and rebuild the seal around each window.

During installation, the windows were sealed from the inside and outside, and spray foam insulation was applied around the frames for improved efficiency. The project eventually included all windows and doors in the home, giving the customer a complete solution for drafts, humidity, and year-round comfort.

Installation Process

The project was completed using a brick-to-brick installation method. Once the old windows were removed, the crew found that the previous windows had not been insulated properly around the framing, which was a major reason for the drafts and humidity problems.

NorthShield sealed the new windows on the inside and outside and used spray foam insulation around each frame to improve energy performance and comfort. The project later expanded to include the remaining windows and doors throughout the home.

Happy Clients!

After the first phase of windows was installed, the homeowner noticed a huge improvement throughout the winter. There was no humidity, no drafts, and a clear difference between the old windows and the most efficient windows installed by NorthShield.

That experience led the customer to order more windows and doors, and the full home project was completed the following year.

Just had new windows and doors put in by Northshield Windows and Doors and they did a fabulous job! The windows are so soundproof that I barely hear any outside noise/traffic. The windows are well insulated so it keeps the house cool in the summer. My AC is hardly running compared to before. The crew worked very efficiently and kept the work site neat and tidy! Highly recommend this company! It took them a day and half to install 11 windows, front and patio doors.

NorthShield finished replacing all my windows, front door and patio door. Since the first time I met with ROBERT DILLON the company sales representative I trusted him his honesty is incredible immediately I dismissed four other quotes from different companies. ROBERT is a pleasant person to deal with always answer the calls or call back. He spent time helping us to choose the right design, he gave us very reasonable price. The installers VITALY and DANIEL did a fantastic job very neat and clean provided careful and professional installation what a great team. My wife and I are very excited with this experience. Thank you NorthShield windows and doors.
