Get started

First things first: Do you need a new patio door?

 

Moisture issues

If you are seeing moisture gathering between the glass panes this could be a sign that it is time to replace your patio door. While some condensation is normal, an excess of moisture often leads to mold and mildew.

Energy efficiency

Determine if your patio door has a draft. If you are experiencing a draft from a patio door your energy bills will increase and your home will feel less comfortable. Drafts are a good indicator of an incorrectly fitting door and updating your patio door will create a more energy-efficient home.

Not working properly

Older patio doors have a tendency to break down and can become difficult to open or close. When your door doesn’t close properly, it can become a safety concern.
