Experience The Difference Of New Home Windows

Our highly trained and experienced window installation specialists make replacing or installing new windows easy with our long line of products to select from. Say goodbye to drafty rooms with uneven temperatures! Our window installation will seal out all the elements and keep your home comfortable no matter what season we're in.

Our windows are highly durable, which makes them resistant to Ontario's harsh winters. This also means you won't have to do any upkeep or repainting. Our ENERGY STAR windows will undoubtedly offer top-of-the-line efficiency in reducing your energy costs. High-quality, energy-efficient windows are an excellent investment and can pay for themselves quickly. They're always a good investment for your home.

What Makes Vinyl Windows The Best Option?

There are many benefits of why vinyl windows are the best option for replacement windows. Vinyl is a durable and low-maintenance material that will not rot, warp, or corrode.

Vinyl windows are high quality, durable and easy on the wallet. They never need painting or refinishing once installed, making them low maintenance and easy-to-care-for window material. Vinyl windows hold up against Ontario's weather and retain their colour exceptionally. Fully-welded sashes and frames make vinyl windows solid and durable, too. Our vinyl window product lines come in 20 standard exterior colours. You can even custom paint them for even more fine-tuning.

The three main reasons why vinyl windows are the best windows you can install are that they're high quality and performing, affordable and easy to maintain.

  • Exceptional Performance

    Vinyl windows are the best option for exceptional performance. They are durable and energy efficient, making them ideal for new construction and replacement projects. The material won't expand and contract during the different weather seasons here in Ontario. The seal will always remain tight, like the day it was installed.
  • Affordable & Easy On The Wallet

    Vinyl windows are a very high-quality material if you're looking to have new windows installed in your home. They're also the most affordable window material on the market, so you can get them without breaking the bank.
  • Low-Maintenance

    Since vinyl windows are easy to clean and never need to be repainted or refinished, they are a low-maintenance option. Vinyl windows also resist wear and tear from exposure to elements over the long term.

Let's talk about your new windows today!

What Are The Benefits Of Window Replacement?

Replacing your old windows with new vinyl windows can provide a range of benefits for your home. It's not only about the upgraded visual look you'll get. Are you noticing fog and condensation between your windowpanes? Are your current windows hard to operate, or are they more than 15 years old? If so, now might be a good time to install new vinyl windows in your home. When you replace your windows, you can enjoy all these benefits.

Improved Aesthetics And Curb Appeal

Window replacement is one of the best ways to improve the aesthetic of your home and its curb appeal. Replacing old windows with new ones can give your home an updated look and feel while increasing its value. With a wide variety of window styles, colours, hardware and grille patterns, you can customize your home to achieve the look you want. For many people and many home styles, symmetrical designs look best in the front of the house. On the other sides of your home, more freedom can be taken to go for a more modern look.

Energy Star Efficiency

Opting for window replacements can help improve energy efficiency by utilizing materials such as IntegraWeld Fusion Welding and energy-efficient features like Low-E coatings, argon gas, and double or triple-pane glass, as well as numerous other upgrades and features depending on the model of window you choose.
These materials and features help insulate the home more effectively, reduce air leakage and lower the amount of ultraviolet light coming into the house, thus reducing energy bills.

Enhanced Security

Replacing your windows with a superior-quality hardware product will increase the durability and security of your home. Open/close and lock/unlock sensors are available, allowing you to keep your home safe and secure. Features such as triple glass, foam-filled frames, multiple-chamber frames, and fusion-welded corners add to the security of your window.

Reduced Noise Levels

Window replacement can reduce noise levels by providing improved insulation in the frames and soundproofing. Newer, energy-efficient double or triple-paned windows absorb daily outside sounds. Foam-filled frames, argon-filled glass, laminated glass, and Low-E coatings also offer excellent insulation and noise cancellation, resulting in an improved overall soundproofing effect.

Improved Comfort

When it comes to replacing windows in a home, they can significantly improve the comfort of a home by providing increased ventilation, higher air quality, and reduced outside noise. Thermal efficiency is greatly enhanced through multiple-chamber frames and sashes, and excellent soundproofing is achieved. The contoured design of newer windows also creates a more modern aesthetic and feel.
For example, horizontal sliders and casements allow for maximum air circulation. At the same time, picture and fixed windows block the elements better. A strategically-oriented casement window can even draw breezes into your home.

Canada Greener Homes Grant Rebates

Replacing windows is a great way to improve the value of your home and save money on heating and cooling costs. To help make the financial burden of replacing windows easier, the Canadian government offers the Canada Greener Homes Grant Rebates. This grant provides up to $5000 in rebates to homeowners who install certain energy-efficient products in their homes, including replacement windows. With this grant, homeowners can enjoy the benefits of window replacement, such as improved insulation, better energy efficiency, and lower heating and cooling bills, without breaking the bank.

You can learn more about this program on the Gentek website.

Cost Savings On Utility Bills

Having your windows replaced is an effective way to save money on your utility bills by creating a better seal for the home and installing energy-efficient features like Low-E coatings, double or triple-paned glass and argon gas. These features can help reduce energy consumption and decrease the air that can escape.


Our windows come with a Limited Lifetime Warranty to the original homeowner of the installed windows. You'll have peace of mind knowing these windows were built to last, and should anything come up, the warranty will cover you. We also provide an unbeatable Lifetime Workmanship Guarantee.

Increase Your Home Value

Replacing windows can significantly increase the value of a home in many ways:

  1. The increased curb appeal from new windows can be a significant draw for potential buyers.
  2. New windows can improve energy efficiency, meaning lower energy bills for the homeowner and more savings for potential buyers.
  3. Impact-resistant glass, up-to-date locks, and security sensors provide extra security and peace of mind.

Installing new windows can be a worthwhile investment that can add substantial value to a home.

A Complete Range Of Vinyl Window Types To Choose From

We install the full selection of all the popular vinyl windows types and styles on the market. We have you covered no matter the functionality you're after in your new window installation. And with numerous customization options, you'll be sure to match the windows to your home and personal taste.

awning window

Awning Windows

Awning windows are a popular and classic choice for living rooms, dining rooms, and bedrooms. They are hinged at the top and open outward effortlessly, providing excellent ventilation and natural light.

casement window

Casement Windows

Casement windows are an excellent choice for energy efficiency and durability, providing reinforced ventilation and a sleek airflow-controlling design with additional multi-lock security features. They usually open wide and outward like a door. They open with a hand crank, which can act as a stopper to resist wind when open and lock for security. Their versatile design makes them suitable for any space in your home.

picture shapes windows

Picture & Shapes Windows

Picture windows are a type of window that does not open or close. They are typically used to provide a clear view or to let in natural light. Picture windows can be found in various sizes and shapes. They can be used alone or in combination with other types of windows.

double slider window

Slider Windows

Slider windows are a type of window that opens horizontally by sliding along a track. They're an excellent option for tight spaces because they don't protrude into the room when they're open. Slider windows are also a good choice if you want to maximize your view because they have larger glass panels than other windows.

double hung window

Single & Double-Hung Windows

Single-hung windows are a popular and economical type of window. The bottom sash slides up and down, while the top sash is stationary. Double-hung windows have two operating sashes that move up and down, allowing for ventilation on the top, bottom or both.

bay bow windows

Bay & Bow Windows

Bay and bow windows are window types that protrude from a home's exterior. Bay windows are typically three-sided, while bow windows are generally four-sided or more. Both bay and bow windows let in more natural light and provide a wider field of view than traditional windows, forming an elegant curve along your space.

basement hopper window

Hopper Windows

Hopper windows are hinged at the bottom and open from the top, making them easy to open even if placed high up on a wall. They're ideal for spaces that need ventilation but may be challenging to reach. They're popular in basements because of their design and features.

Our Vinyl Window Product Features

No matter what type of vinyl window you're after, they all come with these industry-leading features.

Top-Tier Construction

Fusion-welded sash and masterframe provide superior strength and structural integrity, while neat, tight corners create a sleek look. Heavy-duty metal gives extra security to your window and makes it easier to install hardware.

Energy-Saving Design

Thermally efficient frame and sash construction use high-performance insulated glass units to block the transfer of heat and cold. This helps keep your home comfortable in both warm weather and cool seasons.

Renovation Masterframe

The bevelled exterior masterframe on double hung, slider and casement helps the window accommodate differing installation methods and architectural styles.

Design Versatility

A generous selection of window accessories ensures the perfect finish for your home. From brickmoulds and jamb extensions to painted interior windows in casement, awning and picture shapes, our vinyl windows have everything you need to make your home look its best.

Super Spacer® Non-Metal Spacer System

A key component to a window's energy efficiency is the spacer system, which creates an insulating air space between the panes of glass. This non-metal design eliminates any metal-to-glass contact, thereby increasing the edge of the glass temperature by more than 16 degrees – resulting in 60% more energy efficiency than a traditional box metal spacer.

Have Questions about Your Window Replacements? Check Out These Common Questions We Get Asked Frequently

  • What are the advantages of window replacements?

    Window replacement has many advantages, including improved energy efficiency, increased home value, and reduced maintenance. New windows can also help to reduce noise pollution and improve the overall appearance of your home.

  • How much does a window replacement cost?

    The cost of a window replacement can vary depending on the size and type of window and the number of windows being replaced. Generally speaking, vinyl windows are more affordable than other types, making them a popular choice for many homeowners.

  • What do I need to know before replacing my windows?

    There are a few things to keep in mind before replacing your windows. First, you'll need to decide what type of window you want. There are many different types of windows available on the market, so it's vital to do your research and find the one that best suits your needs.
    The most important question you'll want to decide on is whether you're going for a pocket replacement or a full-frame window replacement.
    Full frame window replacements are when the entire window, including the frame, is replaced. Pocket window replacements are when only the glass panes are replaced, and the frame is left intact.

  • When is the best time of year to replace windows?

    You can install new windows any time of year, even during winter months. So if you need new windows, you don't have to wait for warmer weather. Keep in mind that during the installation process, your home will be colder if you choose to replace your windows during the winter, as the outside air will come in while they are replacing your windows.

  • How long do windows last?

    How long windows last is a common question we get asked. Several factors can affect the lifespan of your windows, including the type of window, the quality of the installation, the quality of the material of the window, and the level of maintenance.

  • What are the benefits of double-pane windows?

    A double-pane window is made up of two panels of glass, separated by a spacer system. The spacer is a thin strip of material that helps to seal the two panels of glass together.
    The pocket of space between the two panels can be configured with gas to make the windows more energy efficient and block out more sound from the outside.

  • What are the best replacement windows?

    Generally speaking, the best replacement windows will be the most energy efficient. But there are a lot of other factors like design, style, colour and material to suit your personal preference, as well as keeping within your budget. Vinyl windows are the best bang for your buck as they offer high performance, affordability, low maintenance and a lifetime warranty.

  • Is it best to replace all my windows at the same time?

    If you're considering replacing your windows, you may wonder if it's best to replace them all simultaneously. There are a few things to consider when making this decision.

    If you want to replace your windows for energy savings, it is best to do them all at once if they fit your budget. But if you have a broken window that needs replacing, you can do just the one to match your current windows.
