How Much Do Windows Cost In Ontario?
Let’s break down replacement window costs by factors such as window style, window size, and whether they are energy-efficient windows or not.
Average Window Replacement Cost by Material
Choosing the right window frame material is a key decision in window replacement, as it affects not only upfront costs but also durability, energy efficiency, and aesthetics over time. For instance, vinyl windows are the most affordable option, offering durability and low maintenance, but may lack aesthetic appeal for some. Wood windows offer a classic look with excellent insulation, but come at a premium due to higher maintenance needs.
Let’s look at a comparison of the performance and the average costs to replace windows in Ontario by material, including vinyl, wood, composite, fibreglass, and aluminum.
Average Window Replacement Cost by Style
When planning your window replacement project, it’s helpful to understand how different window styles affect pricing. Certain types, like casement windows, bay windows, or double hung windows, offer specific functional or aesthetic benefits, but they also tend to cost more due to complexity and materials.
Let’s now take a look at the average cost to replace windows in Ontario by window style, excluding labour costs.
Basement Window Replacement Costs in Ontario
Basement windows are an essential, but often overlooked part of a home, particularly in Ontario, where building codes and insulation needs are strict. Let’s now explore basement window costs, including the cost to install egress windows in your basement in Ontario.
Basement windows are typically smaller, unless they are egress windows, which are required to be a minimum size with an unobstructed opening area of at least 20”x 24” with a net clearance of 5.7 square ft. Egress windows are legally required in basement bedrooms, and typically involve a more extensive window installation.
Overall, window replacements may be costly, but they last 15 to 25 years, giving you one of the highest home renovation ROIs at around 71% to 78%.
Other Factors that Impact Window Replacement Costs
The cost of new windows in Ontario can vary widely, depending on a number of factors as we’ve already discussed. By understanding what influences pricing, you’ll be better equipped to budget effectively and choose the right options for your home.
Let’s look more closely at the factors that affect the house window replacement cost:
Size
Larger windows naturally cost more due to increased window material and installation labour. When planning your budget, consider the desired size and total number of windows you plan to replace.
Installation Difficulty
The complexity of the installation process affects the average cost of replacement windows. If the job is intricate, requiring the removal or modification of old window frames, the cost will increase. The age and condition of your existing windows, as well as your home's specific features, will determine the window installation cost.
Energy Efficiency
Windows play a crucial role in your home's energy efficiency. Energy-efficient windows incorporate special coatings or features that improve insulation properties, reducing heat gain in summer and heat loss in winter.
ENERGY STAR-certified windows are the best way to be sure that your windows are fully maximizing energy efficiency. ENERGY STAR is a government-backed program that finds the most energy-efficient products in many fields. They are the most reliable energy efficiency seal, and only 15 to 30% of products meet their strict standards, which boosts home value.
