How to Repair a Sliding Patio Door
A variety of issues can cause difficulties in operating sliding patio doors. Luckily, most of these issues can be fixed easily.
The easiest method to repair your sliding patio door is by cleaning it. You'll want to use a brush and soapy water to thoroughly clean the tracks. Then, you can lubricate the tracks to improve their performance.
1. Tracks that are dirty or damaged Tracks
One of the main causes of a squeaky or sticky patio door is dirt and debris in the track. Sand and salt from winter roads, pine straw, bird droppings, pet hair, and other unpleasant things can clog the works. This is why it's important to clean and lubricate your sliding doors regularly.
Start by putting on some rubber gloves and a pair of safety glasses to shield your eyes. Use a shop vacuum or a brush to clean any loose gunk. Mix equal parts of water and white vinegar into a spray bottle. Spray a small amount of the solution onto your cleaning brushes and scrub the track. Rinse and dry the area using paper towels. This will prevent scratching and further damage to the track and sill.
When the tracks are clean then grab your toothbrush and go in there to scrub the tougher areas that are stuck. You can also sand away rough spots on the bottom track and then re-lubricate your rollers to bring them back to smooth operation.
Another reason for a sticky door is the misalignment of the rollers and can be remedied by adjusting the height and positioning of the rollers. When you replace the weather stripping, it's a great idea to do this to ensure a secure fitting and improve energy efficiency.
Leaking tracks are also an issue that can lead to mold growth and structural damage in your home. It is possible to fix the problem yourself when the leak is restricted to a small portion of the track. Simply seal the joint. If the problem is widespread, you should call a professional to fix the patio door.
2. Broken or Torn Screen
If your patio door doesn't allow airflow, it can make your home feel stale and uncomfortable. It can also create a cozy entryway for mosquitoes and other pests. If you've got a damaged screen or see fog growing between the panes of glass, it's best to contact a professional as soon as possible.
If you have an old screen on your patio door, it is easiest to replace it with a brand new screen. You can purchase screen material in rolls that are already measured to fit the majority of standard door sizes. It's also offered in complete screen repair kits that include screen, spline and roller all in a single package.
The process of installing a new screen begins by laying the replacement material on a solid surface. Then, using your scissors, cut it to length to the point that about an inch or two of the screen overlaps on both sides of the frame. Next, remove the old spline and any screen that is left over from the window frame with your utility knife.
You can now lay the new screen spline starting at the lower left corner of the frame. Then, work your way up until you reach the perimeter. Once the spline has been put in position, run your screen rolling tool over it several times to push it into the groove of the frame. Remove any excess spline and screen using a utility blade making sure not to cut the inner frame of the window. Examine the spline to determine if there are any distortions or ripples. Adjust the screen if needed.
3. Leaking Seals
If you see water pooling or trapped between the glass panes of your patio door, it is a sign that the seals and frame have lost their strength. This can lead to rot and mold as well as increased energy costs due to air leakage and drafts.
Caulking and flashing that is not properly installed can result in leaky seals. To prevent this from happening, it's crucial to work with a professional who has expertise installing patio doors and can ensure the frame is properly flashed and caulked.
You'll need to fill any cracks or gaps with caulking that is suited to your specific kind of weather. If you live in a region that has humid climates, such as Ontario and the like, then you'll need to choose caulking products that are able to stand up to humidity.
The shims that are installed beneath the door frame could also cause leaks. They are usually made of wood and help to keep the sheathing even with the framing, however if they're not placed correctly, they can cause a gap that allows moisture into your home.
One method to test the seals by spraying the frame with the help of a garden nozzle or hose. If you notice the presence of a mist in these areas, contact an expert who will visit and conduct a more thorough inspection of the installation. It's possible that a little more caulking is all that's required, or maybe the shims have to be replaced. In any case, addressing these issues quickly will prevent costly repairs and damage down the road. It is always best to repair your frame or patio door before it's too late than to put off repairs.
4. Warped Frame

When wood is exposed to outside forces like a fluctuation in humidity, it may absorb and lose moisture, which could cause the frame to become warped. A frayed frame can make it difficult to operate the door, and eventually cause damage or even failure. This is particularly relevant for doors that separate garages and basements with damp living spaces.
A few minor repairs can generally correct a frame that is warped. Start by examining the frame to ensure that all of the bolts and screws are tight and secure. Replace any loose or missing screws. Replace the hinge screws with larger ones, with a preference of 2 inches or more. This will allow the screw to pierce the wall framing instead of the door jamb and pull the frame back into place.
You can also include shims. These are thin pieces that can be put in front of the hinges. This will allow you to tweak how the frame is set. Shims can help to support the frame and spread the weight evenly across a wider area that will stop the frame from becoming stretched over time.
For more severe frame warps you may want to consider hiring a professional to fix the issue. A professional will inspect the frame thoroughly to determine the extent of the problem and offer a complete solution. They can also install bracing in order to strengthen the frame to keep it from sliding. This is usually the most durable and cost-effective alternative to buying new patio door components. If the frame is significantly warped, you may require replacing the entire jamb of the door, not only the door itself.

The good news: most cosmetic damage can be easily repaired with bonding fillers and paint. However should the door have significant dents or cracks, it will be best to replace it rather than trying to repair it.
Like the seals around windows, doors' weatherstripping could be less effective as time passes. It can result in gaps that allow outside air to enter your home, leading to higher energy bills. A professional in door repair can install new weatherstripping to decrease energy loss and improve insulation.
Moisture around the exterior of doors is always a problem however, it's particularly dangerous when it comes to your patio doors. This moisture can lead to wood rot which is expensive and difficult to fix. Water leaks should be repaired immediately by an expert.
