How to Fix a Leaking Gutter
A leaking gutter can be very annoying, especially if it is above a door. However, a bigger concern is the structural damage that a constant flow of water can do to your walls. Fortunately, with modern guttering, there are ways you can repair any damage yourself. In this blog we explore the causes of a leaking gutter and a guide on how to fix any problems.
What are the Causes of a Leaking Gutter?
There are many reasons why your guttering may start leaking.
General wear and tear
As with any fixture or fitting on the outside of your home, guttering is susceptible to general wear and tear. Heat, snow, ice, rain, and wind will all have an impact on the general condition of your guttering and over time may cause damage.
Blockages
Leaves, dirt, and general debris can build up, forcing water to find an alternative path. Over time this can cause lasting damage to your guttering.
Damaged Seals
A missing or damaged seal is one of the most common reasons for a leaking gutter. Regular maintenance checks will help you identify any potential issues and replace seals before they cause a leak.
Incorrect installation
If guttering is incorrectly installed, leaks may develop where it has been poorly connected.
Damaged Gutters
Damage can be caused to guttering in several ways, from leaning a ladder against it to extremely windy weather, which can all lead to holes, tears, and other damage.
How to Repair a Leaking Gutter
The good news is that most leaks can be repaired easily. There are three main options from which to choose; clean, repair or replace.
Clean your guttering
Debris can build up and create a blockage which can put pressure on gutter joints and seams causing a leak. This can be easily rectified by clearing the blockage and cleaning your guttering. If this does not resolve the leak then there is most likely a hole, crack or damaged seal that needs repairing.
Repairing holes and cracks in your guttering
Cracks and holes cannot be repaired through cleaning, and whilst replacing your guttering will always be the best solution, you may be able to remedy the situation by using guttering sealant or weather-proof tape.
If using sealant, ensure the area is clean, apply the sealant to the inside of the crack or hole, and spread it around the surrounding area with a flat tool or finger – if you are wearing gloves! Repeat this process to the outside of the damage. Once dry, test the repair by pouring water into the gutter.
Repairing a hole or crack with waterproof tape is just as easy. Again, ensure the area is clean before you start applying the tape. Apply overlapping stripes of tape to both the inside and outside of the hole or crack, ensuring that there are no bubbles or holes in the tape. Once finished, test your repair by pouring water into the gutter.
Repairing a guttering joint by cleaning the seal
The first thing to do with a leaking gutter joint is to check that the seal does not have any dirt or grit trapped inside. Firstly, unclip the affected fitting and drop it in a bucket of warm soapy water. Using your hands or a soft sponge, clean the fitting including the seal, before rinsing of any excess soap. Finally, dry the fitting thoroughly before replacing the fitting. You can test the joint by pouring clean water over the joint.
Repairing a guttering joint with a sealant
If the above does not resolve your leak, you may need to replace the seal. This should be easy by simply removing the old seal, cleaning away any debris, dirt, and grit, adding the new seal and refitting the joint.
Another option is to use a sealant or silicone. Firstly, ensure that you use a sealant specifically for roofing and guttering. Next, unclip the gutter joint that sits over the affected seal and make sure the seal, and the surrounding area, is clean. Use your sealant gun to apply a line of sealant around the inside edge of the existing seal. Finally, reattach the guttering. Once the sealant is dry, you can test the seal by pouring water over the joint.
Replacing a guttering joint
If your guttering is beyond repair, you may have to replace the entire joint. With most modern guttering systems, this should be a simple task by following the manufacturers instructions. Generally, you will start by unclipping the gutter from the union piece and removing it carefully. Next, remove the current gutter union and take this opportunity to clean the ends of the gutters. Now you can install your new joint fitting, apply silicone lubricant to the seal, and fit your gutters back into place.
