Everything You Need to Know About Sliding Door Handles and Patio Door Functionality

Sliding doors are a popular choice for many homeowners, offering easy access to patios and outdoor spaces while letting in natural light and saving interior space. However, with this convenience comes a set of unique components and functionalities, particularly regarding door handles and locks. 
Below, we answer some of the most common questions about sliding door handles and explore how to keep your sliding door functional and secure.

How Do You Replace a Sliding Door Handle?

Replacing a sliding door handle is a straightforward process, although it requires a bit of patience and attention to detail. Here’s a short summary:

• Gather Your Tools: To replace the handle, you’ll need a screwdriver, a new sliding door handle and lock set.
• Remove the Old Handle: Locate the screws holding the old handle in place. These are usually found on the interior side of the door. Use the screwdriver to remove these screws carefully, holding onto the handle as you remove the last screw so it doesn’t fall.
• Remove the Locking Mechanism: Some sliding door handles have a lock integrated into the handle, while others have a separate lock mechanism. If your handle has a lock, you’ll need to carefully remove the locking mechanism by unscrewing it from the door.
• Prepare for the New Handle: Check that the new handle matches the configuration of your old one. Install the New Handle: Align the new handle over the screw holes and tighten the screws securely. Be cautious not to overtighten, as this can strip the screws or damage the handle.
• Test the Lock: If the handle includes a locking mechanism, test it several times to make sure it engages smoothly with the strike plate.

Replacing a sliding door lock handle is generally straightforward, but if you encounter issues with alignment or the handle not fitting, consult the door manufacturer’s instructions or give us a call.

Can You Have a Secondary Lock on a Sliding Door?

Many sliding doors come with built-in locks on the handles, but additional security options are available if you’re looking to increase protection. Here are some types of secondary locks you can install on a sliding door:

• Foot Bolt Locks: These locks are installed at the bottom of the sliding door. When engaged, they prevent the door from sliding open. Foot bolts are often used as secondary locks for added security.
• Security Bars or Rods: A security bar is a metal or wooden rod that fits into the track of the sliding door, preventing it from opening even if the primary lock is compromised.
• Double Bolt Locks: This lock type is installed on the door frame and connects with the sliding door to lock it securely in place. Double bolt locks are known for providing extra strength against forced entry.

With these options, you can secure your sliding door in various ways, depending on your needs and budget.

Are All Sliding Door Handles the Same Size?

No, sliding door handles are not all the same size. There are many different sizes, shapes, and configurations of handles, depending on the brand, model, and age of the door. This variance can affect the installation of replacement handles.

To ensure a proper fit when replacing a handle, measure the following aspects of your existing handle setup:

• Screw Hole Spacing: The distance between the screw holes is crucial. Standard spacing is often 3-15/16 inches, but this can vary widely. Measuring the distance between the center of one screw hole to the center of the other will help you find a handle that fits.
• Handle Backplate Height and Width: Some handles are larger or more prominent than others. Check the dimensions of your current handle to make sure the replacement will cover any pre-existing holes or recesses on the door.
• Lock Mechanism Size: If the handle includes a locking mechanism, make sure the lock matches the original’s size and configuration to align with the strike plate.
• Door Thickness: Some sliding door handles are designed for thicker or thinner doors. Double-check your door’s thickness to ensure compatibility with the handle you purchase.
• Thumb Lever Latch Location: If your handle has a thumb lever, ensure the replacment handle has the thumb lever in the same location as your existing. Some handles will have an Offset lever latch and some will have Center lever latch and some handles will allow you to use the lever in the offset or center position. The lever position is in relation to the mounting screw holes on the backplate. 

When in doubt, give us a call to ensure you get a compatible replacement. 

Can I Replace My Sliding Door Lock?

Yes, you can replace the lock on your sliding door if it’s no longer functioning or if you want to upgrade it for added security. Here’s how to approach the replacement:

1. Determine Your Lock Type: Identify whether your sliding door lock is built into the handle or if it’s a separate lock mechanism such as a mortise lock. Some locks, like foot bolts or double bolt locks, are easier to replace independently, while handle-integrated locks require handle replacement.
2. Find a Compatible Lock: If replacing a separate lock such as a mortise lock, measure the current lock’s dimensions and locate a similar model to avoid misalignment with pre-existing holes. For handle-integrated locks, look for a replacement handle with a similar locking mechanism.
3. Remove the Old Lock: Use a screwdriver to carefully remove any screws securing the lock. Be mindful not to damage the door or the handle during this process, especially if you’re working with glass doors.
4. Install the New Lock: Position the new lock in place and secure it with screws, ensuring it aligns correctly with the door frame. If it’s a handle-integrated lock, attach the handle first, then test the lock to confirm it engages properly with the strike plate.
5. Add Additional Locks If Needed: If you feel the lock isn’t secure enough, consider installing an additional lock like a foot bolt or security bar for extra protection.

Replacing a sliding door lock can improve security, but if you’re unsure about the process, consulting a professional is always a good idea to ensure the lock is installed correctly.

Additional Tips for Sliding Door Maintenance and Security

To keep your sliding doors functional and secure, consider these maintenance tips:

• Regularly Clean the Tracks: Dirt and debris in the track can prevent the door from sliding smoothly and even affect the locking mechanism. Use a vacuum or soft brush to clean out the track periodically.
• Inspect the Rollers: Over time, the rollers on the bottom of the sliding door can wear down, making it difficult to open or close the door. If you notice issues, it might be time to replace the rollers.
• Check the Lock Alignment: Make sure the lock aligns correctly with the strike plate on the door frame. Misalignment can prevent the lock from fully engaging, compromising security. Also check the rollers are properly aligned so the door is square in the frame.
• Install a Security Bar for Extra Protection: If you live in an area with high break-in rates or just want added peace of mind, a security bar placed in the track can provide an extra layer of security.

Sliding doors offer a stylish and convenient way to access outdoor spaces, but it’s essential to ensure they’re well-maintained and secure. By understanding how to replace handles and locks, as well as the different options available, you can enhance both the functionality and safety of your sliding doors.
