How to Choose Between Types of Windows

Choosing styles and material will depend on several considerations, including the interior design and exterior style of your house, the unique needs of different rooms in your house, your lighting and insulation needs, as well as your budget.

When replacing your windows, consider what you need for the room, since your choice of living room windows may be very different from what you choose for basement or bathroom windows. Do you want to maximize the amount of light, is privacy your main consideration? Are you mostly worried about heat loss and energy efficiency? Do you want extra windowsill room for plants or a panoramic view? Do you want them to be easy to open for fresh air, or do they need to be fixed in place?

10 Factors That Affect Your Replacement Window Installation Cost

Number of Windows

How many windows you need replaced will directly impact the cost of your house window replacement and installation project

Size of Windows

Generally, the larger the windows are for your house window replacement project, the higher the average cost to replace windows will become

Type of Windows

When it comes to the types of windows you want installed, you have a range of choices, from casement windows, sliding windows, picture windows and more. Your house window replacement cost will depend on which ones you choose

Type of Glass

Choosing from double pane or triple pane glass, laminated glass, low-UV glass, tinted glass or other available window glass options will affect your window replacement cost

Type of Frames

Wood window frames or vinyl window frames vary in price, but even within the two options, features such as type of wood or enhanced insulation will impact the cost of your project

Insulation

The best replacement windows and frames are designed with insulation features. You may also need to budget for additional insulation to be installed in or around your new windows and window frames to reduce heat loss and improve energy efficiency

Additional Components

Your house window replacement project may require additional work, such as the installation of new sills and casing around new window frames. This work will be added to your window replacement cost

Labour

Your house window replacement requires the labour of a skilled Home Depot Installer. Larger or more complicated window replacement projects take longer to complete and carry a higher labour cost

Your Location

Access to materials and labour may vary from one location to the next and will be factored into your house window replacement cost

Warranty

All replacement window installation projects from The Home Depot Home Services come with a 1-year pars and labour warranty. Ask your Installer for additional extended warranty options

Why Should I Choose Vinyl or Wood Window Frames?

When choosing the right window frames, vinyl and wood are the most popular materials. But what you choose will depend on several factors – and even within these two options, there’s a wide range of choices. Here’s what you should know.

Vinyl Window Frames:

Vinyl window frames are typically the more affordable option of the two. Vinyl frames are also are easier to install than wooden window frames. If purchased as basic hollow-core frames, vinyl window frames can be susceptible to some heat and cooling loss; however, this can be rectified easily by choosing an upgraded vinyl window frame design filled with insulation. Vinyl window frames are also easier to maintain than wood frames, since they don’t crack, warp or rot.

Average Window Replacement Cost: $800 per window installed

Wood Window Frames:

Luxurious wood window frames are available in a variety of options, from cedar to Douglas fir, spruce, oak or even mahogany. While they are more expensive to both purchase and install, they can last longer than vinyl window frames with proper care and maintenance. Wood frames offer excellent insulation around your windows. They can be painted any colour you want or, if preferred, stained to bring out the natural beauty of the wood itself.

Average Window Replacement Cost: $1,600 per window installed

How Much Do Energy-Efficient Window Options Cost?

All house window replacement options available for installation from The Home Depot Canada feature a double-paned design with low-E argon to guard against heat loss; however, some upgrades allow further efficiency improvements. Choosing triple-paned glass costs about $200 more per window, while other improvements such as window frame options with extra insulation will cost about $50 more per window.

Unfortunately, glass is a poor insulator on its own, which means that most of the heat and cooling loss in your home typically occurs through your windows. This is why the best replacement windows are all designed to reduce drafts and ensure optimal performance and weather-resistance for your new windows and will be factored into your overall house window replacement cost.

What Are My Options for Energy-Efficient Windows and Frames?

Choosing upgraded insulation options for your replacement windows and frames can help you boost energy efficiency in your home, potentially saving money on your utility bills. They accomplish this in four ways:

1 Double- vs Triple-Paned Glass Options

The best replacement windows are constructed of double-paned glass or even triple-paned glass. The principle is simple: add more layers of glass to the window’s design to improve insulation. These days, double-paned window options are essentially the standard; however, adding a third pane of glass can improve efficiency significantly – by some estimates, as much as 20 per cent. Upgrading to triple-paned glass for your house window replacement, however, carries a higher cost.

Additionally, the space between each pane is usually filled with an inert gas like argon or krypton, which works to insulate your home even further from heat and cooling loss.

Average cost to upgrade from double-paned to triple-paned windows: $200 per window

2 Insulated Frame Options

While materials such as wood are solid and naturally good insulators, vinyl window frames are hollow by design. For improved energy efficiency, some homeowners may want to consider upgrading to vinyl frame options that have been filled with insulation.

Average cost of upgrade: $50 per window

3 Coated and Tinted Glass Options

Some energy-efficient house window replacement options use glass manufactured with a Low-E glass coating that reflects infrared light. This is especially useful for keeping excess heat out of your home in summer as well as keeping it inside your home in winter. Low-E glass also blocks out ultraviolet light, which can cause furniture and other interior items to fade over time.

Average cost of upgrade: $50 per window

4 Adding Insulation Around Your Windows

This is perhaps the most simple and cost-effective solution to boost efficiency and reduce heat and cooling loss. In many cases, it’s a simple matter of adding a layer of caulking or weatherstripping around the perimeter of your window frames. All replacement window installations from The Home Depot Canada include an application of spray foam around your new windows, at no additional charge.

Average cost of upgrade: $0 (already included as part of your installation)

Can I Save Money by Installing My Own Windows?

While you may be able to save on your window replacement cost by purchasing high-quality stock windows and related products off the shelf at a Home Depot store, and installing them yourself, hiring a Home Depot Installer and ordering custom-fit windows opens you up to a wider range of house window replacement options at a range of price points to suit your needs and budget.

As well, remember that professional house window replacement and installation from The Home Depot Home Services offers you not only the expertise and high service standards of our experienced installers, but also a one-year parts and labour warranty that’s included in all of our house window replacement and installation packages.

In some cases, such as when you require custom-fit windows, professional house window replacement and installation may be your only suitable option to get the windows you need for your home.
