NorthShield replaced 24 windows in a Markham home over three stages during a 12-month period. The project updated the look of the house, solved drafts and cold glass surfaces, and improved winter and summer comfort with full-frame replacement, Energy Star Most Efficient windows, high-efficiency glass, and multi-point locking systems.
Most Efficient Window Replacement Project in Markham, Ontario
Three-Stage Window Replacement in Markham
This project was completed in Markham, Ontario, over three stages during a 12-month period. NorthShield replaced 24 windows in total: the front windows first, then windows on the back and side of the house, and finally the remaining windows to complete the full-home upgrade.
The homeowner wanted to update the look of the house and improve energy efficiency. One of the major complaints was that the old windows had drafts around the frames and the glass surface felt very cold in winter.
Most Efficient Windows for Winter and Summer
All windows used for this home were Energy Star Most Efficient products selected for strong performance during both winter and summer. With proper full-frame replacement and high-efficiency glass units, the homeowner noticed a major improvement through the first winter and summer after installation.
High-efficiency windows can reduce how long the furnace needs to run in winter and help the AC run less often in summer. For homeowners comparing glass packages and performance, NorthShield’s window energy efficiency guide explains how glass, frame design, and installation work together.
Multi-Point Locking for Airtightness and Security
Each window included a multi-point locking system to improve air tightness, increase the overall energy efficiency of the window, and provide additional security. This was especially important for a homeowner who wanted both comfort and a stronger finished system.

Northshield replaced our upstairs windows in July, and we could not be happier with them. Thanks to Alex who guided and informed us through the whole process, and who always was available to answer our questions. The pricing was transparent and quite reasonable. The installers were efficient, professional, and worked neatly. The quality of the windows was a massive improvement over our previous ones.
