There are a few ways to repair plastic guttering, depending on the type of damage that has been done. If the guttering is cracked, you can use a sealant or adhesive to fix it. If there is a hole in the guttering, you can use a patch to cover it up. And if the guttering is bent or twisted, you can try to straighten it out using heat or force. If you're not sure how to fix the damage yourself, it's best to hire a professional to do the job for you.

There are a few ways to repair plastic guttering. One way is to use a special sealant that can be inserted into the crack or hole and will harden overnight. Another way is to use a patch made specifically for this purpose, which can also be bought at most hardware stores. If the crack or hole is too large, you may need to replace the whole section of gutter. This can be done by taking down the old gutter and replacing it with new sections - make sure you get the same type of plastic gutter so that it matches the rest of your system.
