What Affects Window Replacement Costs

The cost of new windows in Ontario can change based on several important factors. Knowing about these things will help you make smart choices and set a reasonable budget for your window upgrade. Let’s look more closely at the factors that affect the house window replacement cost: 

Style Selection

The type of window you choose significantly impacts the average cost of replacing windows. Casement windows, which have a crank that moves outward, usually cost more than double-hung windows, which slide up and down. As a result of their unique design and higher material use, specialty shapes like bays and bows naturally cost more.


The chosen frame material significantly impacts the price. 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. Aluminum windows balance affordability and durability, but may not insulate as well as vinyl or wood. 

Consider your priorities—affordability, aesthetics, energy efficiency, and maintenance—when selecting your window material.


Larger windows naturally cost more due to increased material and installation labour. When planning your budget, consider the desired size and total number of windows you plan to replace. 

Replacing several smaller windows with one large window will generally be more expensive despite the reduced number, due to the increased material and labor required for the larger window.

Installation Difficulty

The complexity of the installation process significantly affects the overall cost. Easy-to-access windows are less expensive to install. However, if the job is intricate, needing the removal of old frames or modifying the surrounding framing, 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 prices.

Energy Efficiency

Windows plays 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.

Benefits of Getting Window Replacements

Heating and Cooling Costs

Your home may be heated with wood-burning, gas, or other electrical heat sources. The same goes for air conditioning that you use during the hot summer months. 

With double-pane, low-E coated replacement windows and professional framing and sealing, you get better insulation for all seasons. Not only does this help the environment by using less energy, but it also means that your energy bills will go down. On average, homeowners will save around 8% or more on their monthly energy bills.

Repair and Maintenance Costs

When you get high-quality replacement vinyl windows, like those made by Clera Windows + Doors, you can save a lot on maintenance costs. Unlike wooden or aluminum windows, they don’t warp, rot, or corrode.

They also only need minimal cleaning with dish soap and cloth—an additional benefit to their superior insulation. You can cut overall costs and get better ROI.

Better Noise Reduction

Noise reduction is another benefit that energy-efficient replacement windows offer. The insulation provided by double-pane window glass combined with professional sealing has the power to block off noise from the outside. 

Increased Home Value and Curb Appeal

Putting in good windows and doors that save energy can make your home worth $5,000 to $10,000 or more, as long as the windows are still pretty new when you sell. Getting new windows doesn’t just make your home more valuable—it also makes it look better from the street. 

Is There a Rebate for Replacing Windows in Ontario

The Canadian government previously offered financial incentives through the Canadian Greener Homes Grant to help homeowners offset the cost of replacing windows with energy-efficient models. However, it’s now closed for applications due to high demand.

The Canada Greener Homes Grant offered rebates for various energy-efficient home retrofits, including window replacements. They offered up to $5,000 for windows and door replacements with an ENERGY STAR rating.
