The right patio door can help your home feel larger by allowing more natural light and fresh air inside. When it’s time to install a replacement patio door, you’ll start to notice a couple of signs.

Our patio door professionals at Pella can help you decide when it’s time for a new patio door and help you select the ideal patio door for your home. Here are some signs that it may be time to replace your current patio door.

Your Patio Door is Difficult to Open or Stuck

Inclement weather — rain, snow or even too much sun — can warp your door frame over time. This can cause your patio door to malfunction making it harder to open and close.

Sliding Glass Doors

Sliding glass doors move along a horizontal track. When they won’t slide, the rollers could be damaged or the door might not be level with the track. A professional should inspect your sliding door if it makes a rubbing sound while sliding.

French Doors

A French patio door should swing smoothly outward or inward, depending on the style you have. When the door isn’t working correctly, the hinges could be wearing out and close to malfunctioning. The latch can also get jammed, rendering your patio doors unusable. Old doors can sag and scrape your floor when you close the door. A professional should take a look at your French-style doors if they scrape against the floor or ground when opened or closed.

Room is Too Hot or Cold

Drafts are a common sign that you need a new patio door. When seals around doors age, they can retract and crack leading to an increase in air leaks in your home. Replacing your drafty patio door will make sure your home stays comfortable throughout the year while reducing energy costs.

Visible Gaps or Cracks

It’s time to replace your patio door if you spot gaps between the two doors or between the doors and the frame. This can cost you extra dollars on your energy bills over time. Snow or rain can drip through these openings, leading to damage to your door and flooring. Remove wooden patio doors that are chipping, peeling or blistering. This could be a symptom that the door is deteriorating from the inside.


Your patio door’s seal might be leaky if you can see condensation between the glass. Roomside condensation can also be tied to poor installation or excess humidity. If the seal fails, air and moisture can collect between the glass panes. This can weaken insulation and energy savings.

Broken Glass or Other Damage

Hail can result in major structural damage to patio doors. Replace doors with exterior or glass damage and consider impact-resistant glass.

Outdated Style

A new patio door may help lower your utility bills and enhance your home’s value while keeping up to date with the latest trends. Replacing your older patio door with a newer style is a great way to update your space.
