One of the most common problems that you might face as a homeowner is a plumbing leak. Your pipes are designed to last a long time, however, not forever. Age, water pressure, and outdated materials take a toll on your lines, and you never know when a leak might occur somewhere in your plumbing system.

From strange noises and soft spots to decreased water pressure, spotting these signs early is key to preventing extensive damage. Read on to learn more about hidden plumbing leaks and don’t hesitate to reach out to the expert Denver plumbers at Bell Plumbing, Heating, Cooling & Electrical if you have questions or suspect you might have a leak!

Hidden Plumbing Leaks

A hidden leak with dripping or running water, while not always easily detectable, can cause significant damage to the surrounding areas in your home, including drywall, flooring, and even electrical wiring. And since it’s hidden, this damage can become extensive before signs of the damage are even noticeable.

Galvanized Pipes

Galvanized steel water pipes were once the standard in plumbing. Homes and buildings constructed before the 1960s likely have this type of water pipe. If you haven’t already replaced them, it’s time to consider repiping as soon as possible. Many of these pipes are weakened by corrosion. Neglecting to replace them can result in burst pipes and hidden plumbing leaks.

Detecting Hidden Plumbing Leaks

If you notice water marks or discoloration on your ceiling or walls, or if you smell damp or musty odors throughout your property, leaks may have developed in your home or building. Trained plumbing professionals can remedy the issue very quickly in most cases. However, you can’t contact a plumber to fix a leak unless you know you have one, and since plumbing systems are extensive, with pipes hidden behind walls and in crawlspaces, they can be hard to detect.

Signs You Have a Hidden Plumbing Leak

You can save yourself a headache, not to mention a great deal of money, by spotting the signs of a hidden plumbing leak early on. The following are some common examples of things to watch out for:

Strange Noises behind Walls

Occasionally you may hear groans, hums, or shudders coming from the pipes behind your walls. This isn’t necessarily unusual, but what is unusual is the sound of running or dripping water behind your walls, or rattling pipes.

Soft Spots

Moisture from leaking pipes can damage the surrounding drywall, which will result in soft spots in your walls or floor.

Loss of Water Pressure

A leak can reduce the flow of water from affected plumbing outlets, causing the water pressure to decrease.

Development of Mold and Mildew

Even in cases where leaking water doesn’t cause actual damage to your home, it can still encourage the growth of mold and/or mildew behind your drywall. You may notice a musty, moldy smell accompanying it, which alerts you to the problem even if you can’t see the mold.


Leaks can lead to discoloration on your walls or flooring. You might also notice cracks or bubbling in the paint on affected walls.

Cracked Cement

If your leaky pipe runs under a cement porch or similar foundation, it becomes what is known as a slab leak and can cause cracks in that foundation.
