Clean the area
The first thing you should do following a leak is to remove any water and then clean the area. Use a wet vacuum to remove any remaining water and wipe down the floors and walls affected by the leak. This will also prevent the growth and spread of mildew or mould that can develop when an area that has been damaged by water isn't dried properly.
Next, check for obstructions. Blocked downpipes can cause water to overflow and run through the sides of your property and cause damage to walls, guttering, driveways and foundations. Blockages can be caused by twigs, leaves, and debris in your guttering and downpipe. Ice can also cause blockages in colder temperatures.
In some instances the downpipe that is leaking could simply be blocked. You may be able to dislodge the obstruction using an hose pipe and piece of drain rod or wire.

Before you begin the process of repairing the downpipe, make sure that you're safe by wearing rubber gloves and safety glasses. If you're working at height, always use a solid ladder and ask someone to help you. If you are unable to climb up the downpipe without assistance, it is a good idea to ask someone else to stand at the base of the ladder and hold the hose while turning it to full flow to flush out the downpipe and clear the obstruction. This will let you work from the top of the downpipe and make sure you don't miss any areas that require repair. If the clog continues persist, it's best to take the hose off and use a plumbing snake to clear the obstruction.
Repair the joint

Once the tape is in place, apply a large amount of roof and gutter sealant on both sides of the joint. Press firmly to ensure a secure seal.
If the leak is located on a cast iron downpipe it could be because one of the fixing screws or nails has become loose. Replace the screw with a galvanised screw. Alternatively, the downpipe could be loose due to an ineffective wall plug. If the downpipe is made of plastic the retaining clip could be loose and will need to be replaced.
PEX leaks can result from an uncrimped connector that doesn't seal completely. A PEX crimping tool and an instrument for testing that is usually part of the tool are able to correct this issue.

Connectors for pipes made of rubber or repair sleeves are a different option to fix leaky downpipe joints. These sleeves are flexible and can be wrapped around joints that are leaky. They work well with polyvinylchloride (PVC). You can also try self-fusing tape that forms an impermeable seal that can withstand water for up to three years when applied correctly.
A faulty crimp is usually the cause of leaks in PEX (pressurised Ethylene) pipes. These leaks can be more difficult to fix, but they can be repaired with the help of specially designed tools. You'll need to use an instrument that is specifically designed to have an array of test gauges (also called "go/no go" gauges) that are the same size of your PEX pipes.
