How to Adjust Patio Doors: Step-by-Step Guide

Patio doors are a type of exterior door that is designed to provide access to outdoor living areas such as a patio, deck, or backyard. They typically feature large glass panels that provide an unobstructed view of the surrounding scenery and allow natural light to enter the living space.

These doors can be made from a variety of materials, including wood, vinyl, aluminium, and fibreglass. They can also be designed to be energy-efficient with features such as double-pane glass and insulated door frames.

Patio doors come in a variety of styles, including sliding doors, French doors, and bi-fold doors. Sliding patio doors are the most common type and feature one or more panels that slide horizontally on tracks.

French patio doors feature two hinged doors that swing open from the centre, while bi-fold patio doors consist of several panels that fold together and slide open.

Are your patio doors giving you trouble? Not closing properly, sticking, or making strange noises? It may be time to adjust them. You can do this all by yourself. But first, let us take a look at all the equipment you will be requiring to adjust your Patio doors.

You will require the below-mentioned equipment to adjust the Patio doors:

  • Screwdriver
  • Vacuum Cleaner
  • Long-Lasting Grease Spray
  • Fast-Acting Degreaser
  • A Plain Cloth

(You can easily find all the above-mentioned equipment at your nearest hardware store).

How to Adjust Patio Doors? 

Adjusting Patio doors is not as difficult as it sounds. With a few simple tools and this step-by-step guide, you'll have your doors working like new in no time. So let's get started!

  • Clean the Track 

Keeping track of your patio door clean is an important step in ensuring smooth operation. Any dirt and debris that accumulates in the track can cause problems with the function of the door, making it difficult to open and close. Regularly cleaning the track will maintain its performance and help extend its life.

To do this, start by vacuuming the hardware to remove any large particles, then use a garden hose or other form of pressure washing to clean out any stubborn buildup or stuck-on dirt residue. Finish off with a soft cloth and some window cleaner as needed to give it a good shine. With a regularly scheduled deep clean, you'll keep your all-important patio door functioning properly.

  • Lubricate Sliding Door Track 

Lubricating the track of your sliding patio door can greatly improve both how it operates and how securely it is kept in place. The single best lubricant for this is a silicone-based spray, as this will not only work as a lubricant but also help protect your track from excessive wear and tear due to normal use.

To properly lubricate the patio door track, first ensure there is nothing blocking the sliding doors' movement, then remove any dirt and debris with a soft brush. Once clean and free of debris, spray the moving parts of the track with a generous coat of silicone lubricant and make sure it fully coats all moving parts evenly.

Then wipe off any excess away with a cloth or paper towel before testing the door's movement to ensure proper functionality.

  • Lubricate Accordion Door Track 

Lubricating the accordion door track will help keep debris from accumulating in the accordion folds and prevent sticky or squeaky door operations. When lubricating the track, use a light machine or silicone oil in order to protect the materials against wear and tear.

Silicone oil must be applied directly into each of the accordion tracks and repeated with regularity to make sure your patio door remains in top condition. Lastly, give the track another light wipe with the cloth so no residue is left behind. Taking the time to regularly lubricate your accordion door track could save you from costly repairs down the line.

  • Adjust the Rollers 

Begin by uninstalling the door from its frame and laying it on a flat surface. Then, loosen the screws holding the roller housing in place, but be careful not to let go of any loose parts like springs or clips. Next, hold the lower roller in your hand and turn it counterclockwise until you are able to adjust its height or lateral position.

Once all of the adjustments have been made, reinstall the door and screw everything back together securely. Make sure to firmly tighten all screws after setting your desired height in order to ensure secure placement.

What Causes the Patio Door to Become Misaligned

Patio doors often become misaligned over time due to the following factors-

  • Changes in humidity, temperature, and usage can cause the door to swell or bend.
  • Weatherstripping may also suffer through wear and tear, which can cause air drafts to enter and interfere with the closing seal of the door.
  • Poor installation may not have secured all of the necessary fixings leading to a shift in alignment.
  • The structural integrity of a house or apartment building can lead to the settling of door frames which can throw the Patio's alignment out of whack.

Knowing how these factors contribute to misalignment will help you adjust your Patio door quickly and efficiently.

How to Clean Patio Door Rollers 

Keeping your sliding patio door rollers in good condition is essential for making sure the door functions correctly and operates smoothly. If you find that yours are becoming sluggish, cleaning them should be the first step. To clean patio door rollers, start by using a vacuum cleaner to remove any lint or debris that might have become lodged in the wheels.

Then spray a little WD-40 on a rag and wipe away any residue on the rollers before applying fresh lubricant. Finally, move the doors back and forth multiple times to evenly distribute the lubrication throughout the rollers. With a bit of effort and maintenance, your sliding patio door will be able to slide easily with no resistance.


Once you've made all the necessary adjustments, test the door to ensure it opens and closes smoothly and latches properly. If it still has problems, repeat the adjustment process until it's fixed. To avoid all this hassle, it is wise to invest in good quality doors that require less maintenance and last for a longer period of time. Consider purchasing both internal and external doors from Emerald Doors to get high-quality doors at fair prices.

FAQs on Adjusting Patio Door Hinges 

  • How do you adjust patio doors up and down? 

To adjust Patio doors up and down, start by examining the roller wheels on both sides of the door that ride in tracks at the bottom of the patio door frames. Then use a screwdriver to loosen any screws that are holding these rollers in place and gently adjust them either upwards or downwards depending on your needs - make sure not to adjust too much as this may cause the roller wheel to slip out of its track once it has been tightened back into place.

  • Why is my patio door not sliding smoothly? 

The most common cause of a patio door that isn't sliding smoothly is misaligned rollers, which can be adjusted with the proper know-how and tools. In some cases, an adjustment to the door height may be needed - typically when it's installed on a sloped surface. A thorough inspection of the door and rollers for signs of excess wear or buildup of debris should also be done.

  • Why is my patio door so hard to open and close? 

If you have difficulty opening and closing your patio door, it could be a sign that something needs to be adjusted. Unfortunately, the hardware can corrode over time, making the sliding mechanism too hard to move or even contributing to it becoming stuck in one spot. When this happens, it’s important to not only find out what is causing the issue — but also how to fix it.
