Common Causes of Leaking UPVC Gutter Joints

Understanding what caused the leak will guide you to the best repair method. Some common culprits include:

  • Loose or damaged joints: Over time, UPVC gutter joints can become loose due to weather exposure, temperature fluctuations, or even accidental impact.

  • Perished rubber seals: The rubber seals within the joints can degrade over time, leading to leaks.

  • Incorrect installation: If the gutters weren't installed correctly, the joints may not be properly aligned or fully engaged.

  • Blockages: A buildup of debris like leaves and twigs in the gutters can cause water to overflow and leak at the joints.

  • Ladder

  • Safety gloves

  • Goggles

  • Replacement rubber seals (if necessary)

  • New gutter joint

The specific repair method will depend on the cause of the leak. Here are some common scenarios and solutions that may help you limit the guttering repair cost.

1. Loose Joints

  • If the joint is simply loose, you may be able to fix it by carefully pushing the two sections together until they click securely into place.

  • If the joint is particularly stubborn, applying a lubricant like silicone spray can help to ease it back together.

2. Damaged or Perished Seals

  • If the rubber seal is damaged or has perished, it will need to be replaced.

  • Carefully disassemble the joint, remove the old seal, and fit a new one, ensuring it is seated correctly before reassembling the joint.

  • If the new seals are not compatible then just replacing the whole joint is easier.

3. Incorrect Installation or Misalignment

  • If the joint is misaligned, you may need to loosen nearby brackets to adjust the position of the gutter sections.

  • Once the joint is properly aligned, re-tighten the brackets securely.

4. Blockages

  • Clear any leaves, twigs or other debris from the gutters to ensure proper water flow and prevent overflows that can put strain on the joints. Hiring a professional company to clean the gutters is a good choice if your gutters are high.

Additional Tips

  • Always prioritise safety when working at height. Use a sturdy ladder and consider having someone assist you. Never rest your ladders against the gutter. Always use a ladder stand off and a ladder stabiliser like The Ladder Anchor.

  • Regularly inspect and clean your gutters to prevent blockages and identify potential problems early.

  • If you're unsure about any aspect of the repair or the leak persists, don't hesitate to contact a professional gutter repair service.

  • Always remember to screw the new gutter joint into the fascia board. This will prevent your new joint from moving out of place.
