Leaking Sliding Glass Doors: 6 Causes and Ways to Fix

Leaking Sliding Glass Doors: 6 Causes and Ways to Fix

Sliding glass doors are a great way to blend indoor and outdoor living. Plus, the right patio door can really brighten up a space. However, a big rainstorm or a flood can cause a faulty sliding glass door to leak, leading to a slew of water-related issues. From damaged floors to potential mold growth, a leaking door can negatively impact the safety of your home. Let’s take a look at the six most common causes of leaking sliding glass doors and how to fix them.

Top 6 Causes of Water Leaks Under Patio Doors and Ways to Respond

Were you lounging on your couch when you noticed a pool of water collecting near your patio door? Leaks that spring up from under patio doors can be the direct cause of a few common issues we see frequently in homes. Take a look at the following causes to see if any of them sound familiar:

1. Sliding Glass Door Was Not Installed Correctly

The best way to prevent a leak is to make sure your sliding glass door is properly installed. If your sliding glass door is leaking water from the bottom, especially if it was recently installed, there was likely a problem during the installation process. In this case, you will need to have either a few parts or the entire door replaced.

2. Track Filled With Dirt and Debris

Ever find yourself asking, “Why does my sliding glass door track fill with water?” Frustrating, we know. Between dirt, leaves, and muddy shoes, the track of your sliding glass door can get clogged with all sorts of stuff. This debris builds up over time, eventually breaking the seal between the door track and the actual door. If you notice a buildup of debris, grab your vacuum cleaner and suck up as much dirt as possible.

3. Malfunctioning Track or Rollers

If your sliding glass door is catching on the track or skidding along its rollers, there is a chance the seal is broken. If your door’s seal is damaged, a water leak can find its way into your home. When this happens, issues like mold growth and stains might follow suit. Give a professional a call to take care of your malfunctioning rollers.

4. Maintenance Needs to Be Performed on the Weep Holes

Weep holes are like built-in drains for your doors. As helpful as these slats are, they can easily become clogged with dirt, stones, dust, leaves, and other debris. Look at your door’s model number to find the weep holes. Once you have found them, remove the debris and check the caulking for any damage. If you can’t find the weep holes, call a contractor to receive support with fixing your door.

5. Damaged Door Flashing

The flashing is located at the base of your sliding glass door. If your flashing becomes damaged, it might not drain the water as well as it should. This can cause water to leak and pool in your home, turning a small issue into a big problem. If you can’t fix the flashing yourself, call a professional technician to do it for you.

6. Glass Is Not Sealed

Unsealed glass can cause leaking water over the top of the windowpane on your sliding glass door. This usually happens after years of weather damage. However, it can also happen if your door was not installed the right way. Contact a professional to get to work on repairing your door and preventing future leaks.

Signs You Need to Replace Your Patio or Sliding Glass Door

Sometimes, all your door needs is a quick fix. But you might need a full patio door replacement if you notice one or more of the following signs:

  • Water coming in through the door – Water coming through your door is a clear sign it’s time for a replacement. This issue can lead to water damage, mold growth, and even increased energy bills. If you are dealing with a leaky door, consider a full door replacement.
  • Visible signs of damage – Water will inevitably start to seep through cracks in your patio door. If your door is cracked or damaged in any way, it’s time to replace it completely.
  • The door doesn’t close or lock correctly – Not only is this grounds for a water leak, but it’s also unsafe. A sliding glass door that doesn’t lock or close properly is like an open invitation for water damage and trespassers.
  • It’s hard to open and close the door – If your door doesn’t open or close without some friction or skidding, you could have a bigger problem that goes beyond a simple track fix. Contact an expert for an assessment to see if you need a full sliding glass door replacement.
