Prevent Mold by Fixing Hidden Leaks

How to Find and Repair Hidden Leaks

Discovering your home has extensive water damage is never an enjoyable experience. Not only can moisture cause unhealthy mold and bacteria growth over time, but it can be costly to restore and repair.

Even a small water leak in one area of your home can cause significant mold growth, requiring replacing materials like wood and sheetrock. Our team of professional plumbers at Western States Home Services wants to avoid extensive water damage to your home.

Here's how to prevent mold by locating and repairing hidden plumbing leaks.

Check the Water Meter

One way to check for plumbing leaks is by looking at your water meter. Start by turning off all plumbing fixtures in your home, then write down the reading on the water meter.


Wait for about an hour and then go back and recheck the water meter. If the needle has moved, there may be a plumbing leak somewhere in your pipes.

Look for Water Stains

Another way to tell if there's a plumbing leak is by looking for water stains on ceilings, floors, or walls. These could be small spots that are hard to notice, so it's important to look closely. If you see any discoloration, the culprit might be a plumbing leak.

You should also check for any visible mold growth, as this is often a sign of plumbing leaks. Mold has a musty smell, so if you notice any unusual odors in your home, look for evidence underneath cabinets or in the bathroom on walls and the ceiling.

Check Pipe Fixtures and Appliances

Another common area for plumbing leaks is pipe fixtures like the sink, shower, and toilet. You should also check appliances like the dishwasher and washing machine for any signs of drips or damage.

If you see any water or moisture coming from these places, you likely have a plumbing leak.

Other Leaks to Search For

There are other places in your home where plumbing leaks can occur, so it's important to check these areas, as well. For example:

  • Splash leaks from shower curtains or shower doors.

  • Drain leaks from the shower or tub drain.

  • Sink rim leaks around kitchen faucets.

  • Toilet flange leaks from waste pipes below the toilet.

  • Washing machine hose leaks from the connection to the wall.

  • Dishwasher leaks at the door gasket.

  • Water heater leaks around the tank and base.

Many of these areas sometimes go unchecked by homeowners, giving mold the perfect conditions to thrive and grow. However, you can stop mold in its tracks by looking every once in a while to ensure your home isn't suffering from a hidden leak.

Prevent Mold from Water Damage

Water damage is a big issue in your home, but mold growth is even worse. Even a tiny amount of it can cause significant health issues for your family and pets.

That's why it is important to mitigate damages as quickly as possible once you know a leak exists. Take steps to clean up any visible droplets with dry towels and use a small heater to absorb any additional moisture.

You can also opt to clean visible mildew or mold spots with special household cleaners that contain bleach. Just be careful and follow recommended CDC guidelines before taking on major mold damage, which might require a respirator or face mask to handle safely.

Fixing Hidden Plumbing Leaks

Once you've discovered the source of the plumbing leak, it's a good idea to fix it as soon as possible to prevent further water damage. If the plumbing leak is coming from a pipe fixture or appliance, you should contact your local plumber immediately to assist you with the next steps and inspect for more leaks.

Additionally, if the plumbing leak is coming from a hidden spot, like under the bathroom sink, your plumber will help you fix it. Hiring a professional plumber for this type of task is the best way to save time and money in the long run while also ensuring the problem gets completely fixed.
