The first step is to take the door down and remove it from the frame. You’ll need two people to help you because the door is very heavy and fragile. Once the door is out of the way, you can work on repairing it without worrying about breaking or scratching the glass. 


If your door uses a mortise-style lock, you’ll need to carefully remove the lock body from the pocket carved into the door. This can be a messy process because the lock body can become jammed or stuck. If you’re unsure about your ability to handle this project, consider hiring a professional to do it for you. 

Cleaning and lubricating the tracks

One reason that sliding doors get sluggish is that they have dirt or debris stuck on them. This happens because lubricants that have oil bases can attract dust particles, which in turn prevents the door from moving freely. If you notice this, use some lubricant to clean and lubricate the track before trying again. 


If you’ve tried everything else and you can’t fix the sliding door, you might need to replace it with a new one. Buying a new one is usually cheaper than fixing the old one, and it can be a great way to ensure that you’re getting a good quality product. 

Selecting a Door

When you’re shopping for a new sliding glass door, keep in mind that different styles and materials suit different homes. You’ll want to choose a model that complements your home’s design and is a material you can easily maintain. 

Depending on your budget, you can purchase a model made of wood or aluminum. Regardless of what you decide, it’s important to choose a door that will last you a long time. 

The best-sliding glass door is a sturdy, energy-efficient model that doesn’t need much maintenance. This will save you money over the years and keep your home looking beautiful. 

You can also purchase a new door seal, which will make your sliding door less likely to leak cold air. This will save you money on your energy bill and keep your home more comfortable in the winter. 

If you’re worried about burglars, you can install a security door lock to protect your sliding glass door from unwanted intruders. This type of lock is more secure than a regular keyed door lock, and it features a hidden screw that prevents tampering with the latch. 

Sliding glass door locks can be a little tricky to install. This is especially true if you have never worked with them before. This is why it’s always a good idea to hire a professional who can help you with the installation.
