Plastic doors swell in the summer due to changes in temperature
Plastic doors can swell in the summer due to changes in temperature. This is a common issue with uPVC doors, which are often exposed to the elements. While uPVC is a sturdy material that can withstand wind and rain, it can suffer in the heat. uPVC expands in hot temperatures, which can cause issues with shutting or locking windows and doors. This is because the heat causes the plastic to expand, leading to the door mechanism shifting out of alignment. This can result in the lock malfunctioning or the door becoming difficult to open or close.
The issue of uPVC doors expanding in the heat can be troublesome and may require adjustments to the hinges. It is more common in darker uPVC or woodgrain models but can also occur in white uPVC. To prevent the door from swelling, you can try to keep the plastic cool by pouring cold water onto the frame. However, this may not be effective on extremely hot days. If you need to lock the door, you may need to adjust the hinges or try to cool the plastic down with cold water.
There are a few methods to adjust the hinges and prevent the door from swelling. One method is to tighten the screws on the hinges, which can help align the door correctly. If that does not work, you may need to make more drastic adjustments, such as pushing things out or pulling them in. For example, you can try to push the door out from the bottom and pull it in at the top, which can help pull the door trim towards the framing. Another option is to replace the highest screw closest to the hinge pin with a longer screw, such as a 3" deck screw, to pull the hinge and door trim towards the framing.
If the problem persists, you may need to consider altering the size of the door or replacing it. It is recommended to seek professional advice before making any significant adjustments or modifications to the door. Additionally, ensuring proper installation and setup of the door can help prevent issues with swelling in the summer.
It is important to note that summer also sees more frequent use of front and back doors, as people tend to go in and out of the garden. This can cause extra strain on door hinges and mechanisms, leading to potential problems with physical locks and doors. Therefore, it is advisable to maintain home security during the hot weather and treat unattended windows and doors as a potential security risk.

Warping and swelling can cause the door to malfunction
Plastic doors, particularly those made of uPVC, can swell in the summer due to heat expansion. This can cause the door to malfunction in several ways. Firstly, the door may become difficult to open or close, requiring extra force to operate. This issue can sometimes be mitigated by pulling upwards on the doorknob or slamming the door.
Secondly, the swelling of the door can cause the lock to malfunction. The door mechanism may shift out of alignment, making it challenging to lock or unlock the door. This problem is more likely to occur if the door has been exposed to significant temperature variations, such as a sudden shift from cool to hot weather.
Thirdly, the weight of the swollen door can cause the door trim to pull away from the building frame at the top. This issue can be addressed by removing the highest screw near the hinge pin and replacing it with a longer screw that will help pull the hinge and trim towards the frame. However, care must be taken not to overtighten the screw, as this could lead to cracking or paint damage.
Additionally, the swelling of plastic doors in the summer can cause the door to drop, affecting the alignment of the lock with the door frame. This can be corrected by "toeing and heeling" the door, which involves making adjustments to the hinges to realign the door correctly. It is recommended to seek professional advice or assistance for such adjustments to avoid further complications.
Finally, repeated use of doors during the summer months, such as frequently going in and out of the garden, can put extra strain on the door hinges and mechanisms. Over time, even the most durable mechanisms may succumb to the increased usage, leading to potential malfunctions. Therefore, it is advisable to pay close attention to the condition of your doors during the summer and consider necessary maintenance or repairs to ensure their optimal function.

More frequent use of doors in summer can cause extra strain on door hinges
Plastic doors, particularly those made of uPVC, can swell in the summer due to heat expansion. This can cause issues with shutting or locking doors and windows. When the temperature cools, the plastic will return to its original form, but this may not be ideal if you need to secure your property on a warm summer night.
More frequent use of doors in the summer can cause extra strain on door hinges. As people tend to go in and out of their homes more often during the summer, the door hinges and mechanisms are used more frequently, which can eventually lead to wear and tear. This can be a problem even for the sturdiest of mechanisms. In some cases, the repeated use may require repairs or adjustments to the hinges.
To address this issue, it is recommended to tighten the screws on the hinges, as this may help align the door correctly. If this does not resolve the problem, more drastic adjustments to the hinges may be necessary. It is advised to seek professional advice or assistance when making such adjustments to avoid further complications.
Additionally, the expansion of uPVC doors in the heat can also contribute to the strain on door hinges. The expansion can cause the door to drop, affecting the alignment of the lock and the door mechanism. This may require adjustments to the hinges or even replacement of the door if the issue persists.
Overall, the combination of frequent door usage and heat expansion during the summer can increase the likelihood of issues with door hinges and mechanisms. It is important to be mindful of these potential problems and take appropriate measures, such as regular maintenance and timely adjustments, to ensure the proper functioning of doors during the warmer months.

To fix a swollen door, you can try adjusting the hinges or shaving the door
UPVC, a type of rigid plastic often used for doors, can suffer in hot weather. While it's generally sturdy and can withstand wind and rain, uPVC expands in heat. This can cause issues with shutting or locking your uPVC doors. Although the uPVC will return to its original form when the temperature cools, this may not be ideal if you need to secure your property on a warm summer night.
If you're facing issues with a swollen plastic door during the summer, you can try adjusting the hinges or shaving the door. Here are some detailed steps to help you with the process:
Adjusting the Hinges:
- Check the hinges to ensure they are secure and properly installed.
- Remove one screw from each hinge on the door casing side.
- Replace the screws with longer ones, such as 3" screws, and drive them in so they connect with the stud. This will help pull the door over and adjust its position.
- If the top of the door is twisted or hanging out from the wall due to loose nails, focus on the top hinge. Remove the short screw and replace it with a longer one, then tighten it to straighten the door.
- If necessary, add more screws around the door jambs to secure them to the hardwood timber.
- If the door is simply tight and swollen, you can try running some candle wax up and down the door jamb and the door to create a smoother movement.
Shaving the Door:
- If your door is catching on the bottom of the frame or new flooring, consider shaving some length off the bottom of the door.
- This process can be risky, so it is recommended to seek professional advice or hire a skilled handyman to plane or shave the door.
- If you have a wooden door, you can use a cheap planer tool to carefully shave off a small amount of the swelling. Afterward, repaint the edge to match the door.
By trying these methods, you can fix a swollen plastic door during the summer by adjusting the hinges or carefully shaving the door. Remember always to take the necessary precautions when attempting any DIY tasks.

Doors may need to be replaced if the swelling is severe
UPVC is a sturdy material that is often used for doors and windows. However, like all plastics, it can suffer in the heat. uPVC expands in heat, which can cause issues with shutting or locking your doors and windows. While the uPVC will return to its original form when the temperature cools, this can be problematic if you need to secure your home on a warm summer night.
If your door is swollen, you may need to adjust the hinges or try pouring cold water on the frame. If the swelling is severe and you cannot lock your door, you may need to call a professional locksmith to adjust the hinges or provide other solutions. They may recommend shaving some length off the bottom of the door if it is catching on the bottom of the frame. However, this can be a risky manoeuvre and should only be attempted by someone who knows what they are doing.
If the problem of swelling persists, it may be necessary to replace your door. uPVC doors may not have the longevity of other building materials, and breakages may require replacement. Additionally, if your door has been repeatedly exposed to extreme temperatures, causing it to expand and contract, it may be more susceptible to damage.
While waiting for a professional to replace your door, there are some temporary solutions you can try. You can try to lift the doorknob to engage or disengage the strike plate, and if that doesn't work, tighten the screws on the hinges to align the door correctly. These adjustments may help alleviate the issue until a more permanent solution can be implemented.
