Reduce Costs Of Heating And Energy With Home Window Replacement.  

Windows are not only an essential feature of a great home; they are an important factor in reducing heating and energy costs. 

Eventually, Mrs. CBB and I will have to replace the windows on our home so we wanted to understand the process and prices involved. 

Our home has 2 skylights, a sunroom, a front door, and plenty of windows throughout including our basement.

In terms of our sunroom, we want it to be all-season, French doors, and the best windows so we have no issues.

We recently had a look at a few different window replacement companies for comparison purposes and one of them was Ecoline Windows.

As a homeowner, you must be prepared to replace windows, doors, garage doors, etc., or your home will cost you more in the long-run.

Managing your home’s energy efficiency by evaluating what you currently have makes the process easier. 

Windows, doors and skylights can be a significant source of energy loss in your home – up to 35%. In Canada’s climate, this means higher energy bills for you. – Source

Window Replacement On My UK Home

When I lived in the UK I had all of the windows in my house replaced to double-pane at a cost of 5000 pounds. 

That was back in 2001 and in today’s dollars, that would have cost approximately CAD 8753. 

As we know the cost today will be far more than the 5000 pounds I paid in 2001 which is why a budget is critical. 

Saving your money as a projected expense for your home renovations is a smart way to go rather than using credit. 

It’s important to understand the different window styles and the elements needed for your project.

The price of window replacement also depends on what window is being replaced.

In 2020, the average cost to replace 10 windows in a typical three-bedroom home was between $3,900 and $9,200.

However, the price can fluctuate depending on the number of more complicated windows needing to be redone.

The main factors that affect the price of your window replacement are:

●      Type of installation – such as full-frame vs. Retrofit

●      Styles of windows you choose – such as two-pane or three-pane windows

●      Additional customizations – such as gas fills

Understanding these elements will let more accurately budget for your new window replacement.

How to Build a Budget for a Window Replacement project?

To begin building your window replacement budget, it’s important to understand your window needs.

●      Full frame vs. Retrofit – full-frame installation involves more labour and a more complicated installation process. This type of installation is usually needed if you are looking to change the overall size of your original window. A retrofit uses the existing window frame, therefore reducing the time and labour needed to install the new windows

●      Type of window – different window options can be chosen depending on where the window is located and where you are located. If you are looking for a two-pane window vs a three-pane window, there is a price difference. The benefit of a three-pane window is increased energy efficiency, additional finishes, and increases your home’s potential resale value. If you live in a colder climate it can also ensure a more consistent indoor temperature.

●      Additional features – there are many customizations to windows that will affect the price. One of the most common additional features is having gas fills for your windows. This additional gas barrier will increase the energy efficiency of your window as it helps prevent heat from exiting or entering through the window.

Formulating Your Window Replacement Budget

Once you have identified the type, style, and additional features you can formulate your budget by:

●      Determining the average cost of each window

●      Figuring out how many windows you plan on replacing

●      Researching the availability in your region

●      Planning how quickly you want the project completed

Each of these factors will affect the overall cost of your budget.

But by accurately determining your home’s specific window needs, you will be able to build an accurate budget.

●      Casement – these windows can be single-sided or double-sided. They can also be fixed or operable where they swing open on a hinge from one or both sides. The average cost is $827.

●      Awning – this style of window, has a latch that opens, and the window is hinged across the top. This allows the window to swing upwards creating a ledge. The average cost is $951.

Types of Window Installation

There are two types of window replacement installation:

●      Retrofit Installation – this refers to using the existing window frame. Replacement windows are made to fit the existing space, without the need for additional structural modifications. This is the quickest and most cost-effective method.

●      Full Frame Replacement – this type of installation involves changing the size of the window frame that will house the window itself. This is a more complicated installation process that involves changing the overall structure of your window frame.

The type of installation will affect the labor required for the installation and therefore affect the cost of the project.

On average, full-frame replacement usually costs 10-15% more than a retrofit installation, so take this into account before choosing the type of installation.

Window Replacement Location

The location in which you are replacing the window plays an important part in the overall price of the installation.

For example, a basement window replacement will potentially require the ground surrounding the window to be dug out to fit the new window into place.

If you already have an existing well around the basement window, it can provide easier access.

However, if you are looking to change the size of the basement window, it will require the removal of the existing well, the space being dugout, and a new well being made.

These additional factors will increase the price of the window replacement project.

Similarly, if the window replacement for a skylight window, the process can become more complicated since the windows are in an inaccessible location.

These windows require additional sealing to ensure they are safe from the elements.

Many factors affect the cost of your window replacement project.

However, if the window being replaced is in an easily accessible location such as a main floor living room, this provides easy access for a team to replace the window.

This simplicity will reflect in the cost of the project. If you want to know more about how location affects pricing, see the table below:

  1. Our first house was very close to the neighbors so there were no windows on the sides. I believe total windows and doors was 7. When we bought our current house we were so excited because we have 26 windows and doors. So much light. And the great view. Now we are 20 years later and window replacement is coming up on the project list. I kind of miss our old 7 window house. That said, I would love to get European style windows (they open from side (like a door or casement) or can be opened at the top and tilted to allow fresh air. But they don’t really exist in Canada. I checked out magic windows but the price was ridiculous. So we will probably replace with same as we have now.

    1. Hi Susan,
      I’d be missing those 7 windows too, haha. That made me smile. My mum and dad have the windows you are talking about and no I have never seen them in Canada. Plus, all of our windows had keys for them. I replaced all of the windows in my house to double glazing and although it was pricey It was worth it, especially as a selling feature of the home. Thanks for stopping by. Mr.CBB
