The time to replace your home windows has finally come, and you’re probably wondering how much this replacement will cost you.

If you’re like many homeowners, you may think that window replacement cost is completely in the hands of the window replacement professional. Hiring a pro is just one of the cost factors.

How much will your window replacement cost?

Well, it depends. While this response may not be as satisfying as you’d imagine, it’s an honest one. There are multiple factors that influence the cost of window replacement.

Learn five of these factors here.

1. Size of the Window

Size is a cost driver when it comes to replacing your window. However, it’s not just the obvious thinking “bigger size is more expensive”. One of the key cost factor involved here is whether you will require tempered glass.

In some cases, the window replacement service automatically tempers the window once the window is of a certain size. Tempered glass is considered as an internal safety measure.

More often, the local building codes will demand to specify when to use tempered glass based on factors such as proximity to the floor.

2. Frame Material

Which material are you using for your window frames? Wood or vinyl or metal?

Wood is a popular choice for historic homes. It offers more color options and creates a great visual appeal. But wood is a high-maintenance material and may be costly to maintain over its useful life.

Vinyl is a low-cost material that offers a good ROI. Comparing the two, wood windows are expensive. Counterintuitive as it sounds, wood has a low ROI despite being expensive.

You can also use composite/fiberglass replacement. They are easy to clean and aesthetically pleasing. This is why they are trendy. Due to high demand, window frames made from wood are costly. However, they have a low ROI.

If you want to choose strong window frames that require little upkeep, go for metal frames. These window frames may be expensive to install but are the most economical to use over the long term.

3. Type of Window

The most common window types including single hung units, double-hung units, sliding units, casement units, sash units, bay units, and picture windows. The cost of window replacement varies depending on the type of windows you choose to install.
For example, some windows types such as bay windows require a total reconstruction for their installation. This increases the cost of installation.

4. Window Grid Design

There are different kinds of window grids. They all cost different prices. It’s important to note that just because your current windows have a certain grid pattern, doesn’t mean you can’t change it.

If your current window has a diamond grid, for example, it’s possible to choose a prairie grid, colonial grid or a different pattern altogether.

5. Complexity of Installation

The complexity of the installation determines the total cost. Some styles such as single and double hung windows are easy to install. Most professionals also have experience installing them. This is why they are so common.

However, there are other window designs that require extra reconstruction work and the professionals must be very skilled to install. Some require new framing. This means the studs must be removed and new headers installed afresh.

Your Window Replacement Cost Should Match the Desired Performance

When considering window replacement, the cost of the replacement should be secondary to the performance of your new windows.

Your new windows will affect the energy efficiency of your home in a big way, so you should let window replacement cost stop you from getting the right windows for your home. Keep in mind that drafty windows are the only causes of heat gain or losses in your home.
