Can You Add More Windows to a House?

Although it’s more difficult than replacing existing units, it’s certainly possible to add extra windows. You might benefit from doing this if you want more natural light, a better view of the outdoors or an additional emergency exit. There are several important things to consider when you think about installing more windows:

New Openings

An installer will need to cut large holes in the siding and walls. Some exterior and interior materials make this process easier than others. The project remains feasible if your house has brick or aluminum siding, but it may take longer and cost more.


Keep in mind that a wall could contain electrical, phone or cable wires. It’s crucial for the installer to avoid cutting them. Other potential obstructions include pipes, air ducts and insulation. If these objects can’t be avoided when you select a location, your contractor will need to reposition or remove them.


Depending on where you live, local authorities may or may not expect residents to obtain permits before they replace windows. Creating an entirely new opening is a much bigger project, so you’ll almost certainly need to gain permission before any work begins.


Unlike replacement units, additional windows require new frames and molding. This boosts their prices by around one-sixth and also increases the cost of installing them. On the other hand, more glass could reduce heating, cooling and/or lighting costs if you position it wisely. A greater number of windows also helps your house become more appealing to buyers or tenants.

Despite the added cost and complexity, additional glass can greatly improve your quality of life. It’s best to hire a professional to maximize safety and avoid the risk of water leaks.
