How to Stop Water Coming Through Light Fixture? - FS Drainage

Discovering water dripping from your light fixture can be both alarming and, if it’s not handled right, can ultimately be dangerous both for your family and your home itself. So if you find yourself with water dripping through a ceiling light in your home, what’s the best route of action to take? Let’s take a look.

Common Causes of Water Leaks in Light Fixtures

There are a number of reasons why water might leak from a light fixture. Some of the most common causes include:

• Roof leaks: Water from a roof leak can seep down into the walls and ceiling and eventually reach the light fixture - this usually occurs after a storm or heavy rainfall.
• Plumbing leaks: A leaky pipe above the light fixture can also cause water to drip down onto it.
• Condensation: Condensation can form on the inside of a light fixture if it is not properly ventilated, and this can eventually lead to water leaks.
• Faulty light fixture: A faulty light fixture may not be properly sealed, allowing water to seep in from a leak above.

Immediate Steps to Take

Turn Off Electricity

If you notice water coming through a light fixture, the first step you need to take is to immediately turn off the electricity at the circuit breaker. Water is an excellent conductor of electricity, and its presence in or near electrical fixtures can lead to serious accidents, including electrical shocks. Never attempt to turn off the light switch or touch the light fixture itself if you notice water leaking!

Contain the Water

Next, you’re going to want to protect your home furnishings, so place a bucket or any large container under the light fixture to catch the dripping water. If the leak is severe, you might need towels or a larger container to prevent water from spreading on your floor, which could lead to further damage.

Identifying the Source of the Leak

Check the Obvious Sources

Often, a leak above a light fixture is due to issues in the floor or room directly above, with common culprits including bathrooms or kitchens where plumbing runs. Inspect these areas for any signs of water leakage or damage.

Roof and Attic Inspection

If your leaking fixture is on the top floor under an attic or roof, the problem might stem from roof damage or broken shingles that are allowing rainwater to seep through. This can occur after heavy rainfall or extreme weather, so check these out to eliminate - or confirm - the cause.

How Are Roof-Related Leaks Fixed?

If your investigation reveals that the leak originates from the roof, it's essential to act swiftly. Roof leaks can rapidly worsen, leading to extensive damage to your home's structure and electrical system:

Inspect Shingles and Flashing

Damaged or missing shingles are often the culprits, as well as compromised flashing around chimneys or vents can allow water to seep through. These should be repaired or replaced promptly by a professional.

Check the Gutters

Blocked gutters can cause water to pool and seep into your home, but regularly cleaning your gutters and ensuring they are free from debris can prevent many roof-related leaks.

Professional Roof Repair

For significant roof damage, it's advisable to hire a professional roofer. They’ll be able to provide you with a thorough assessment and undertake the necessary repairs safely and effectively.

Addressing Plumbing-Related Leaks

Plumbing issues can be more complex to diagnose and fix; this is because water travelling along pipes can emerge far from the actual source of the leak, making detection tricky. Here’s what we recommend:

• Look for Obvious Signs: Check for dampness or water stains on walls and ceilings -  especially those directly above the affected light fixture - as this can indicate a leaking pipe.
• Non-Invasive Leak Detection: Modern plumbers use non-invasive methods like thermal imaging to locate leaks within walls or floors without causing unnecessary damage. You can also pour different coloured (washable) food dyes down your toilet, sink, shower, and any other plugholes in your home. As the fixture continues to leak, the colour of the leak will show you where the problem is coming from.
• Repairing Leaks: Once the source of the leak is identified, the necessary repairs should be carried out as soon as possible to prevent further damage. This might involve replacing sections of pipe or fixing connections, but it's best left to professional plumbers who have the skills and tools to do the job correctly.

When to Call a Professional

Whether you have a leaking light fixture or a blocked drain in South London, sometimes it’s best to get the professionals on the job:

When Safety is a Concern

If the leak involves electrical systems or is difficult to access, it's safer to call in professionals. Professional plumbers are equipped with the necessary equipment and knowledge to handle these situations safely and promptly, without causing further damage.

Recurring or Persistent Leaks

If a leak keeps returning or you can't find the source, it's definitely time to call in the professionals. Persistent leaks can lead to mould, structural damage, and other serious issues that can be easily preventable with a swift diagnosis from a qualified plumber.
