How do I fix a leaking PVC Gutter Joint?

A sound PVC guttering system is key to keeping water away from your home and protecting the integrity of the building. To ensure your PVC guttering system continues to function correctly, regular maintenance is crucial. Not only will this keep it looking and performing its best for longer, it will also give you the opportunity to identify any areas of damage or deterioration. You can then deal with these issues before they become a bigger problem. Some issues, such as larger leaks, can be spotted without having to go to the roofline level – these should be dealt with as soon as possible to prevent any serious damage being done to your roof or walls.

So, how do you go about repairing PVC guttering systems? Especially if you have spotted a leaking PVC guttering joint?

Firstly, always be safe. Working at height can be hazardous, so make sure you have the correct equipment and never work alone.

Secondly, you need to match any new pieces of guttering to your existing system to ensure it continues to perform properly. Many systems will look similar but may be dimensionally different. So whether you have half round, deep or square PVC guttering you need to make sure any replacement part you install is compatible.

Thirdly, repairing damaged PVC gutters and pipes is generally more trouble than it’s worth. The simplest solution is to purchase a new part of guttering to replace the damaged piece. One area of concern of a PVC guttering system can be the gasket seals, as over time compression can reduce their flexibility causing leaks. If replacing a gasket seal, you need to make sure it is clear of any debris when refitting to ensure a clean, strong seal. However, if properly maintained, these seals can last for many years with no problems.

Lastly, damaged mouldings, such as fascia brackets, unions, corners, and downpipe clips, are best replaced rather than repaired to ensure the integrity of your whole PVC guttering system. When installing new mouldings, remember to check the screws for deterioration and, if needed, replace with new, stronger ones.

So, overall, replacement is better than repair when it comes to PVC guttering. Regular maintenance will also help to reduce the number of times you have to replace or repair your PVC guttering – saving you both time and money in the long run.
