Windows are the link between the inside and outside, the home’s access to fresh air and natural light. Not only do our windows allow air to enter and circulate around the home, but they also keep rooms insulated, cosy and warm. Windows are a very important feature of the house, so every now and again they’ll need to be updated to suit modern needs. But, how much does a window installation cost exactly?

Replacing windows is not the easiest job, as glass, a very delicate material, is involved. Therefore, if you’re replacing the windows of your home it is important to do your homework and know exactly what’s involved. 

Window Installation Types and Their Cost

Full-frame Installation

Full-frame Installation will happen if your windows need to be fully torn out and replaced. Your old window will be completely removed from its place, and this will include the frame and studs that keep it secure. This style of tear-out and installation is required if there are any issues regarding rotting wood or moisture buildup that has lead to surface deterioration. A window specialist will only be able to deal with these issues if the frame is fully removed.  

Retrofit Installation

Retrofit Installation is an insertion style installation, where new windows are inserted into the frames in place. The jambs will also remain in their spot, and depending on the style of window your home has, aluminium capping may be used to cover up existing brickmould. Retrofit installation is much cheaper than a full-frame installation.

However, a full frame installation will guarantee that any internal issues regarding your windows are looked at and dealt with before they get worse. Sometimes a tear out is simply a cosmetic fix and can lead to serious problems in the long run. Make sure you know what you need before you decide on your installation type. 

Window Installation Costs

• Installing replacement windows, retrofit installation: $130-200 per square foot, $300-800 per window (glass alone)

• Full-frame installation: $500-1500 per window
  

• Installing storm windows: $300-800 per window (glass alone)
  

In some instances, professionals will offer discounts or charge less per window if homeowners are installing multiple units. Window costs can also vary depending on the size of the unit as well as the style of window. Do your research and contact professionals when you're ready to move forward with this project!

Different Windows on the Market

Before we get into our pricing guide, we should first determine the diverse types of glass windows that are available on the market.

Double hung windows

Double hung windows are a style of window that is designed to be opened from both the top and bottom. This style of window is the most inexpensive, and are especially necessary for areas that are hard to reach. As a result, this type of window is one of the most common installed in the average home.

Tilt-out windows

Tilt-out windows are self-explanatory, folding in and out to reveal the exterior of the glass. This style of window is easy to clean, as homeowners can access the outside of the glass by tipping the window inwards. These windows are used in areas with limited accessibility but aren’t as common in households because they are typically more expensive than standard double-hung windows.

Double-pane glass

Double-pane glass is common for its wide availability, as there are several different encasement types on the market. However, this is not the cheapest style window. Double-pane glass includes an airtight space filled with inert gas. This style window is environmentally friendly, assisting in climate control. Further, it blocks out more outdoor noise as compared with your average single paned window. Although this model may cost more initially, it will greatly help to save on utility costs n the long run.

High-performance glass

High-performance glass is the most expensive of the types listed above. There are several types of speciality glass out there, including:

• triple-pane windows, 

• soundproof windows, 

• impact resistant glass,  

• even windows which are tinted to reduce heat conduction.

Depending on your individual needs, as well as your living environment, one of these window models may be right for you.
