Signs of a Hidden Leak In Your Home

Signs of a Hidden Leak In Your Home 

Things get worse when the apparent signs of a leak are ignored. The problem becomes more noticeable and costly when undetected or dealt with too late. There are several signs that your home has a hidden leak in your plumbing. There might be multiple leaks. The water can come from under the sink or toilet, through cracks in the wall or floor, or even out of walls where a vent pipe connects. The most common location for a leak is near a faucet connection in the wall behind your toilet. Neighborhood Plumbing can help you identify the source with their leak detection experience. Often finding the source of the leak is not as straightforward as you'd think. A professional plumber can help you not only find the source but also with leak repair. 

A hidden leak is a leak that a homeowner cannot detect. These leaks may go undetected for months or even years, causing extensive damage to your property and wallet.

Apparent Mold

Mold is one of the first signs of a hidden water leak in your home. If you notice mold growing on the walls or ceiling in a room with no windows or doors, then the plumbing system is likely a problem. This can be due to either a burst pipe or an active leak.

Foul Odors

A foul odor coming from your plumbing system is another sign that you may have a hidden water leak. This odor can be caused by sewage backing up into your home or bacteria that develop in standing water as it sits within pipes and fixtures. The smell will worsen as time passes and more damage occurs to your property.


If you start experiencing flu-like symptoms such as headaches, sore throats, and nausea, it may be due to bacteria growing inside your plumbing system. This bacteria usually thrives in standing water sitting within pipes for several days or weeks without being flushed out regularly by running water from faucets or toilets.

Discolored Walls or Ceiling (Tiles)

If your ceiling is discolored, it may be because of a hidden leak. The most common cause of discolored walls and ceilings is water damage. Water leaks into your home can cause mold to grow and spread throughout your house. The mold will then discolor the walls and ceiling, making them look dirty and unattractive.

Blistered or Peeled Walls

If your walls are peeling or blistered and there are no other visible signs of water damage, it may be because of a hidden leak in your home.

Decreased Water Pressure

If there is an increase in pressure in one area of the house but not another, it may indicate that there is a hidden leak somewhere in the plumbing system. If there are areas with low pressure but no visible leaks, this could suggest a hidden pipe behind the wall that has sprung a leak.

Increased Water Bills

If your water bill has increased, this could be a sign that you have a hidden leak somewhere in your home. The amount of water used will vary depending on how many people live in the home and how much they use it. If you notice that your water bill is higher than normal, check all faucets, toilets, and appliances to see if any of them are leaking or running excessively.

Puddles On The Floor

Puddles on your floor can indicate a hidden leak in your home. Water leaks into walls or floors often seep through cracks and eventually cause mold growth, leading to health problems like asthma attacks and allergies. If you notice puddles on the ground near windows or doors where there shouldn't be any, investigate further to find out where the source of the leak is coming from.

Rusty Pipes

If there are rust stains on any of your pipes outside your walls or on any exposed areas near plumbing fixtures like showers, toilets, and faucets, this is another sign of possible piping problems such as leaks or breaks that can lead to higher water bills.

Always keep an eye on your plumbing and pipes. A tiny drop-like leak can quickly become not only a disastrous but also hazardous situation.
