Clean the area
After a leak, your first thing you should do is to get rid of any standing water and then clean the area. Make use of a wet vacuum to eliminate any water that is still standing and clean up walls and floors that were affected by the leak.

Leaks in downpipes are often caused by the joints. The joins are often exposed to harsh weather conditions and dirt and debris.
After you've cleaned your area and checked that it's dry, cut a piece of repair tape about one centimetre larger than the length of the leak. Remove the backing paper and wrap the tape around the joint. Once the tape is secured then apply an ample amount of roof and gutter sealant on both sides of the joint. Press firmly to achieve a solid seal.
If the leak is on a cast iron downpipe it could be because one of the fixing screws or nails has come loose. Easily remedied by replacing the screw with a new galvanised screw. It is also possible that the downpipe might be leaking because of a faulty wall plug. If the downpipe is constructed of plastic, the retaining clip may have become loose and need to be replaced.
PEX leaks can be caused by a crimped connector that isn't sealed completely. This can be easily corrected with an PEX Crimp Tool and a test gauge, which is typically included with the crimp tool.
Epoxy putty can also be used to repair the leaky downpipe. It can be molded into a sausage-like shape that fits the joint of the pipe. Just wipe the pipe's surface to ensure that it is dry, apply the putty to the affected area, making sure to cover the whole crack or hole.

Cover the area to be repaired and wait for several minutes, or according to the instructions in the instructions of the product, until the cast hardens.
Pipe repair clamps can be used to repair leaky downpipe joints. They are available in various sizes depending on the gutter's width. These devices use the gasket of a metal with an elastic band to repair leaks along the length or end of the pipe. Remove the bolts that are holding the clamp, then place it on a leaky joint. Then tighten the bolts to ensure that the gasket is pressurized against the pipe.
Repair sleeves are another option for fixing leaky downpipe joints. They are flexible and can be swathed around a leaky joint. They are compatible with polyvinylchloride (PVC). Self-fusing tape can be used to create a compression seal which will resist water for up three years if it is properly applied.
PEX (pressurised ethylene) pipe leaks are usually caused by a weak crimp at a connection. These leaks can be repaired with specialized tools. You'll require a specialized crimp tool with an assortment of test gauges, known as a "go/no-go" gauge that is the same dimensions of your PEX pipe.

Before beginning, turn off any electrical fittings, fixtures or cables near the downpipe. It is also recommended to wear safety glasses and rubber gloves.
