How to Know When It Is Time for Window Replacement

Most homeowners will find that total window replacement is the best choice. This process involves removing and replacing the entirety of the window unit itself as well as the frame. Replacing both the window and frame can help lower energy costs and protect your home from the elements. Read ahead for some common situations in which it is best to replace the entire window.

You Want to Upgrade to More Stylish Windows

If you are looking to upgrade the look of both the interior and exterior of your home, it is always a good idea to replace your windows. At WindowTech Windows and Doors, we have a wide selection of options for window trim, PVC jamb extensions, and corner blocks.

You Want to Improve the Energy Efficiency of Your Home

Have you noticed that your energy bills had been higher than before? If you have not replaced your windows Toronto for quite some time, you might notice that in addition to higher energy costs, you may be experiencing more drafts in your home due to leaks in your window units. At WindowTech, all of our windows and doors are manufactured using state-of-the-art equipment and the latest technology to bring you the most energy efficient doors in the GTA. Our ENERGY STAR certified windows are made with an airtight seal to be able to stand up to even the harshest weather conditions.

Your Existing Window Frames Are No Longer Adequate

One of the most common reasons why homeowners choose to replace windows is that they have noticed some problems with their existing window frames. Older frames tend to warp or rot due to aging, which can lead to air leaks and other issues, such as mold or mildew. If your window frames are damaged beyond repair, full window replacement is the best option.

Those who do not need total window replacement can opt for retrofit windows, which is replacing the window unit only. Older homes with high-quality construction as well as newer homes are the best candidates for retrofit window installation.

Thanks to modern advances in window glass manufacturing, homeowners have a large selection when it comes to choices for window glass. Some of these options are Low-E glass and warm-edge spacers. Low-E, or low emissivity, windows provide outstanding insulation from cold weather due to their triple glazing. Warm edge spacers not only improve the energy efficiency of your home, but they will also help keep a comfortable indoor temperature all year round. Those with damaged, leaky, single pane, or older windows might want to consider retrofit window replacement.

What We Provide

At WindowTech, we rely on our decades of experience to help each and every customer find the best windows and doors for their Toronto area home. Whether you are a new homeowner or have owned your home for years, we will be able to provide you with the most energy efficient, stylish, and practical windows for your home.

With our professional and knowledgeable service, you will be sure to receive the personal attention you deserve when it comes to window replacement. We pride ourselves on our high standards for customer service and will grant you the best selection of windows and doors that will give you long-lasting value. We will be happy to discuss with you why awning windows might be the ideal choice for your home or why casement windows could be more beneficial in some cases. We can help you decide if it is finally time to upgrade from wooden windows to energy efficient and elegant vinyl windows.

All Windows Replacement.

All work was done very professionally. Schedule was honored and work finished in time. I am very happy with my new windows.



Vinyl is considered to be one of the best materials due to several reasons, including its energy efficiency, durability, aesthetics and low-maintenance properties. Vinyl is a superior insulator which prevents heat transfer, and by being extremely flexible, it is moldable to create multi-chamber frames resulting in even greater energy efficiency.
Due to the durable make-up of extruded vinyl, the frame will not require repainting, since it does not crack, peel or chip, and maintains its color regardless of the sun’s rays or other damaging weather elements. Easily cleaned with soap and water, it is virtually the lowest-maintenance material available for windows and doors to date

It is important to note which exact features make a window or door energy efficient, since they directly impact the energy consumption of the house, heating costs and the environmental impact. Windows are considered to be energy efficient when the frame is made of high-quality material such as 100% extruded vinyl, when the glass is made of multiple panes filled with insulation gas such as Argon, when Super Spacer technology is present, and the glass is coated with Low E or Low E 2 coating which reflects the heat. Doors are considered to be energy-efficient when the core of the door is insulated with foam, the composition material is solid, the frame is a tighter fit to the spacing, and multi layered weather stripping is used.

There are a variety of signals that all homeowners should be aware of, indicating that it is time to replace your existing windows or doors:

Increasing energy bills could indicate that your windows or doors are not fulfilling their role as thermal control mechanisms, either from loose frames or a lack of water/air tightness in insulation. Windows should prevent drafts and air leaks, and if either of those appear, it is time for a replacement.

Visual and aesthetic signals are often the most evident of all, including broken or cracked glass, peeling paint or frail and weakening aluminum. Rotting frames are also one of the best indicators, since a poor frame can dispel all the advantage of even the best-quality window, including superior insulation and security.

The formation of ice or frost on the windows signals condensation build-up from rapid changes in temperatures. This often occurs when low quality or weakened insulation and thermal materials allow air to infiltrate too quickly with rapid changes in temperature

Most installation projects will take one or two days; however, for porch enclosures or very-large scale replacement windows projects, up to three days may be required. However, all of our customers can be sure of clean and non-intrusive installations with dust rugs being used at all times to protect your floors. All garbage and debris will be removed upon completion of the day’s work

Windowtech believes in employing only the highest quality professional in-house installers, whose training and expertise we can guarantee as a mark of the company. Our installers will take your projects from start to finish, starting from precise measurement for custom-manufactured units, to a signed customer satisfaction report upon completion. All of our installers are fully licensed and insured with WSIB Canada. No sub-contractors are used in any project installations, to ensure reliable and long-lasting projects.

Our goal at Windowtech is to ensure that customers make a fully informed decision based on all available information and can clearly decide on the best option for them. This is why we provide a completely complimentary on-site consultation by one of our expert technicians who will be able to inform our clients of the entire installation process, financial requirements and the best suitable options for the desired projects. From a professionally experienced opinion to a variety of catalogue options and life-window presentation, our non-obligatory consultation will be sure to answer all your questions.
