Casement windows come in a large variety of designs, sizes, and materials, and work well in combination with other types of windows when designing your home.

Attractive and secure front entry doors are essential for beautifying any property while keeping its inhabitants safe.

Steel is also a popular choice for modern apartment buildings, where a more contemporary look is desired.


Your entry door provides your home with a wide variety of benefits that are essential for your comfort and security as a homeowner. They are responsible for controlling your privacy and keeping your home safe from intruders, along with blocking out external noise.

Other Factors That Affect Your Replacement Window Installation Cost

Number of Windows

The second most important factor affecting the cost of your window installation project is the total number of windows you choose to install.

For smaller replacement projects, it can be more cost-efficient for homeowners to replace individual windows based on increasing their functionality or aesthetic appeal, or to save on renovation costs by repairing damaged windows individually, keeping your project within your budget while meeting your needs.

However, as a general rule, replacing all of your windows at once is the most efficient option for homeowners looking to save big in the long run. Not only will your total project cost most likely be reduced compared to that of working on individual windows in bulk, but upgrading all of your windows to eliminate any potential leaks or drafts will save you on energy bills down the road.

Size of Windows

The size of your windows can have a major impact on the cost of replacement and installation. Smaller windows are generally cheaper to install, as they are less labour-intensive. This is because they require less material and take less time to install.

If your window is an odd size, custom frames may need to be ordered, adding to the cost. Additionally, if your window needs to be framed differently than a standard window, extra labour and materials may be needed, increasing the installation cost.

When determining the total cost of your window installation project, it's important to have a good understanding of the scope of your design ideas, as well as the sizes of your windows and how many of each type you will be installing. Typically, while smaller windows tend to range between $400-1,000, medium ones run at a slightly higher range of $600-1,200. Meanwhile, large windows can cost as much as $1,200-2,000, and extra-large ones $2,000 up to $4,000.

Types of Window Installation

Retrofit Installation

During retrofit window installation projects, the existing frames of your windows remain intact while new panes of glass are installed into the openings. This type of installation is generally more cost-efficient, as the majority of your window's construction has remained untouched, leading to less work needed and less time spent by your contractor.

If your original window casings are still performing efficiently and don't need any repairs, your window replacement company will be able to measure the exact sizes of replacement panes you need in order to give you a tailored quote that factors in the installation of new double-pane, UV-protected glass.

Ultimately, retrofit installation projects can help you save big on costs down the road without causing too big of an intrusion on your home.

Full-Frame Installation

When it comes to a full-frame installation project, your team of installers will remove both your window itself as well as all of its surrounding structural elements, eliminating any hidden damage or rot from the inside of your frame in order to solve any potential moisture problems. This process typically involves more work than a retrofit installation project, and involves a more complex process that costs about 15% more.

Full-frame installation is best for homeowners looking to address underlying structural issues around their windows, such as excess moisture or rotting wood. The installation process involves setting up new jambs, interior trim, and exterior moulds, and is most often recommended for newer construction projects in existing buildings, along with larger wall remodels.

Window Location

The location of your window can have a major effect on the total cost of installation. If your window is located on a second or third story, additional labour costs will be incurred due to the need for scaffolding or ladders. Windows located in basements or near electrical or plumbing lines may also incur additional costs due to the need to take extra care to avoid damage to these lines. Additionally, windows located on the outside walls of your home will require additional insulation, which can increase the cost of installation.

More difficult access to replace the window may also increase the cost, due to the need to rent additional tools or materials. In addition, replacing windows on the upper floors of your home often requires more advanced equipment and labour, adding to the total cost of your project.

Determining the total cost of your window installation project can be a challenge, especially when estimating before the project has begun. As a general rule, replacement living room windows tend to range between $300-$1,000 in cost, with bay and bow windows increasing these values significantly. Meanwhile, kitchen windows range between $300-$2,500 to replace, while bathroom and bedroom windows both cost approximately $300-$1,000 each. Lastly, basement windows tend to cost between $200-1,000, with egress windows raising this price up to anywhere between $2,000-$5,000 due to their function as emergency escape paths – usually located in bedrooms - in the event of a fire.

Type of Glass

The type of glass you choose for your window replacement can drastically affect your overall cost. Single-pane glass is the most basic and least expensive option, but it is also the least energy efficient. Double and triple-pane glass is more expensive, but also offers superior insulating properties, helping you save on energy costs down the road.

If you want a high level of insulation and soundproofing, you may want to consider installing laminated or Low-E glass, as laminated glass is more impact resistant and safer than traditional window glass. Ultimately, the type of window glass you choose will have a large impact on your installation cost, so it is important to weigh the pros and cons of each option before making your final decision.

Type of Frames

The type of window frame you choose for your replacement window can have a significant effect on the overall cost of installation. Wooden frames tend to be the most expensive option, as they require more labour and materials in order to install. Meanwhile, vinyl frames are a more cost-effective option, as they are pre-painted and require less labour during the installation process, while aluminum frames are relatively cost-effective, as they are corrosion-resistant and lightweight, making them easier to work with - however, they may be more expensive than vinyl frames depending on the type of finish you choose. Finally, fibreglass frames are the most expensive option, as they are the most durable and require more labour to install.

Ultimately, each type of frame material offers its own set of benefits and drawbacks, and it is important to consider which option is best for your home when investing in new windows. When it comes to Canadian homes, vinyl windows offer homeowners the best balance between price and quality.


The type of insulation used in your home affects the installation cost of replacement windows. If you have fibreglass insulation, replacement costs will usually be low, as fibreglass is easy to install and is usually the most cost-effective choice. However, the downside to fibreglass insulation is that it is not as effective at keeping out the heat and cold as other types of insulation.

Meanwhile, when it comes to spray foam insulation, you will likely pay more upfront, but you will also get better energy efficiency and improved air quality. Cellulose insulation is also another option that is slightly more expensive than fibreglass, but it is more effective at keeping out the heat and cold.

Additional Components

Replacing your windows involves a lot of planning and care, and may involve additional components that aren't as common or predictable as others. Your project may require other structural efforts, such as the installation of new sills or casing, for example, which may affect the total cost.


When it comes to window renovation and installation projects, the labour costs associated with hiring a professional team of installers vary depending on the company you are working with, along with the number of windows you are installing, their measurements, and their style and glass type.

In order to get a good understanding of how much your total window installation project will cost, it's important to schedule an in-home consultation to receive an estimate from a number of different companies in order to find the one that best matches your needs.

Your Location

Where you live can have a significant impact on the cost of window installation in your home. Depending on your location, a contractor may need to travel further to get to you, thus increasing the overall cost. Additionally, the cost of labour and materials can vary depending on the local market - if you live in a rural area, you may find that labour and material costs are higher than in a more urbanized area due to the limited availability of materials and contractors.

In addition, local codes and ordinances can have major impacts on the types of glass and frames your replacement project requires, often depending on the climate you live in. Colder climates rely on the insulation and energy-efficient properties of triple-paned windows, while warmer ones tend to benefit more.


Warranties can have a significant impact on the final cost of your window replacement project. If a product is under warranty, it generally means that the manufacturer will cover any installation costs associated with the product. This can be a major cost saver for homeowners, as installation can often be the most expensive part of the replacement process.

In addition, some warranties may cover both parts and labour, meaning that homeowners can save even more money. On the other hand, if a product is not under warranty, you will usually have to pay for the installation out of pocket, which can add significantly to the cost of the replacement. For this reason, it is important to research the warranties associated with a product before making a purchase, as it can make a big difference in the total cost of replacement.


Gas-filled windows affect the cost of window replacement and installation projects in a few key ways. Depending on your choice, the cost of the window itself can be more expensive, as double or triple glazing will contain a special type of gas, such as argon or krypton, between its panes. This gas helps to insulate better than air would, and thus increases the efficiency of the window. In addition, gas-filled windows will require a more thorough installation job than a regular window, which can also add to their cost. This is because the window must be carefully sealed in order to keep the gas inside and prevent any leaks.

Cost Saving Tips for Ontario Window Replacement

Replacing windows can be expensive, but there are a number of cost-saving tips you can rely on within Ontario. Look into energy-efficient windows and energy rebates, and remember to shop around for the best deal. Also, consider weatherstripping or caulking to reduce air leaks, and research window tax credits and grants available in your area.

Use a Trusted Contractor or Window Company

When replacing your windows, it is important to work with a trusted contractor or window replacement company in order to save money in the long run. A reliable contractor or company will provide quality products and services at competitive prices. They will also be able to provide advice and guidance on the best windows for your home, taking into consideration factors such as size, style, energy efficiency, and installation cost.

Working with a trusted contractor or company can also help to ensure that your windows are properly installed, and that any future repairs or replacements are covered. Additionally, experienced contractors and companies may offer discounts for multiple window replacements, or for customers who purchase high-efficiency windows. By working with a trusted contractor or company, you can save money while feeling at ease in knowing that your windows will be fitted and maintained professionally.

Go Energy Efficient

Energy-efficient windows are designed to reduce the amount of energy lost in your home through air leakage and the transfer of heat from the inside of your home to the outside, which can help keep your home more comfortable and reduce your energy bills down the line. Additionally, investing in energy-efficient windows can help you qualify for rebates or tax credits from your local utility company.

Energy-efficient windows also help protect your home from the elements by providing an effective barrier to the outdoor environment - this barrier can help reduce outside noise and keep your home comfortable. Energy-efficient windows also have an improved lifespan, due to their improved insulation properties and airtight seals. This means that you won't have to replace your windows as often, saving you money in the long run.

Apply for the Canada Greener Homes Grant

The Canada Greener Homes Grant is a financial assistance program offered by the Government of Canada to help Canadian homeowners make their homes more energy efficient. This grant is available to homeowners who have made improvements that increase the energy efficiency of their homes, such as upgrading their insulation, replacing inefficient windows, or installing solar panels. This grant can also help offset some of the costs of these projects, making them more affordable and allowing homeowners to save money on their energy bills in the long term.

The Canada Greener Homes Grant is open to both first-time home buyers and existing homeowners, and the amount of assistance available varies depending on the type of improvements made. Homeowners who are eligible for the grant can receive up to $5,000 in assistance to cover the costs of their energy-efficient upgrades.

Overall, the Canada Greener Homes Grant is a great way for Canadian homeowners to make their homes more efficient while saving money on their energy bills. By taking advantage of the financial assistance available through Big City Windows & Doors, homeowners can make their homes greener and more affordable in the long term.

Replace More Windows at Once

Replacing all of your windows at once can save you valuable money in the long run, as your energy savings alone can help you offset the cost of your new windows. New windows are much more energy efficient than old ones, meaning that your utility bills will be lower - this is especially important in climates with extreme weather, as improved insulation properties will help keep the temperature inside your home comfortable. Additionally, replacing all of your windows at once means that all of your windows will be the same style, size, and colour, making your home look more cohesive and visually appealing.

Finally, having all of your windows replaced at once can save you money in labour costs, as your contractor only has to come to your home once. All in all, replacing all of your windows at once is a cost-effective way to improve your home's energy efficiency, visual appeal, and resale value.
