Convert Windows into Patio Doors

Do you want to bring more light into the living areas around your home? Why not convert one of your windows into patio doors? Adding a door onto the patio or other outdoor areas around the house is a great way to increase your property value and curb appeal. It also gives your space a more functional way to get in and out of the house.

While most window and door companies only do simple replacements, CMC has performed many of these window-to-door conversions. 

What are the Benefits of Converting a Window into a Patio Door?

Why convert a window into a French door or sliding glass door? Is it worth it? Here are the top benefits you can expect from this conversion.

Bring Light Into Your Home

Turn that dark, gloomy room into a well-lit space. Bring in the light and get more out of your living area.

Improve Your Property Value

Adding French or sliding doors to your home boosts your property value and curb appeal.

Move Freely Between Rooms and Outdoors

You get direct access. Move from a room to the patio without walking around the house.

Energy Efficiency

Your old window may be inefficient or cause drafts within your room. This can cause energy bills to be much higher than necessary.

Better Air Circulation

Open the sliding doors on breezy days and feel the airflow through your home.

A Better View 

Converting windows into sliding glass doors or French doors can give you a better view of your yard or scenery. 


Choosing the Right Window to Convert to Patio Door

There are several components involved when we convert windows into sliding glass doors. If your window is as wide as the door you are wanting to install, then the process is much easier. We will be able to use the existing header that runs the top width of the current window.

You won't need a header replacement if the window is wide enough to accommodate a patio door. Standard single door widths range from 32 inches to 40 inches in width while 2-panel French doors and sliding glass doors typically range from 5 feet wide to 8 feet wide.

Some homeowners choose to install a patio door wider than the existing window. In this case, we will need to expand the opening horizontally and install a new header to run the new length of the proposed door. Many of our customers choose to fit French or sliding doors when converting windows to doors in their homes. Sometimes the current window opening will be wide enough to accommodate new doors when converting a bay window into a patio door or multiple windows into a door.

We carry a huge selection of patio doors for your project. Some of the top manufacturers we use on our projects include leading manufacturing brands like Anlin, Marvin, and Pella.
