Signs to Look Out for When Detecting a Hidden Plumbing Leak

Hidden leaks can cause a lot of damage to your home if they are not fixed quickly. Water can seep through the cracks and cause mold to grow. The thing is, mold is a serious health hazard and can cause respiratory problems. If you have a plumbing leak, it is important to call a plumber to fix the problem as soon as possible.

That said, if you want to know the usual signs of a possible hidden plumbing leak, look no further than our examples below.

  1. There Are Stains on the Walls
    Don’t ignore small amounts of water, as they could be indicative of a larger problem. Water stains on ceilings, walls, and floors can be caused by water droplets in moist, cool environments. Over time, these droplets can soak into the structure, causing damage.
    This type of water damage is often not discovered until it’s too late.
  1. There Are Visible Signs of Mold and Dirt
    When there is a plumbing leak, the humidity in the air will increase. This will cause mold to grow, and you may be able to see it or smell it. If the mold is easy to wipe away but keeps coming back, then there is a hidden plumbing leak. Mold can grow in areas where there is condensation or standing water.
  1. There Are Floor Cracks
    One warning sign that your floor may need to be replaced is if you notice cracks in the floor. These cracks typically form when the wood has become repeatedly soaked and dried, which can cause the subflooring to shift.
  1. The House Has Water Pressure Problems
    If you notice a sudden drop in water pressure, it may be an indication of a plumbing leak. This is often caused by damage to the pipes, joints, or fixtures, which can cause water to escape.
  1. The Water Bill Has Gone up Mysteriously
    If you see higher water bills than you’re used to, it’s a good idea to chat with a plumber to figure out why water is being lost. Your water company will often let you know if you’re using more water than usual.
    The more water that’s leaking, the greater the impact on your bill will be.
  1. The Toilet Is Unstable
    If your toilet is wobbly, it might mean that the ground around it has lowered, or there could be an issue with the pipes. Inspect the flooring and the pipe connecting the toilet to the sewer line. A toilet that sways back and forth as you use it could leak from the tank. The water level in the toilet must be even.
  1. The Backyard Grass Stays Wet
    Water may be leaking from a broken sprinkler system and dripping onto your property. The individual with the leak may not even be aware of it.

    Any areas of your yard that seem to be developing grass or other plants more rapidly than usual, as well as any areas that appear to be consistently damp, should be given extra care. These areas may be indicative of an underground leak in your home.


If you think you may have a hidden plumbing leak, there are a few key signs to look out for. First, check for any unexplained increases in your water bill. Second, look for any water stains or puddle water in your home, especially in areas where there shouldn’t be at all. And finally, listen for any strange sounds coming from your plumbing, which could indicate water leaking through pipes. If you notice any of these signs, it’s important to call a plumber immediately to fix the leak before it causes further damage.
