Find Hidden Leaks Before They Cause Damage
A hidden plumbing leak can waste hundreds of gallons of water, drive up your utility bill, and quietly damage your home long before you ever see a drip. From moisture behind walls to leaks under concrete slabs, these problems often go unnoticed until real damage sets in.
That’s why professional leak detection and repair is so important. At Fosh Plumbing & Heating, Inc., we support homeowners to find leaks early and fix them correctly, before a small issue turns into an expensive repair.

Signs of a Leak
Not every leak shows up as standing water on the floor. Many leaks stay hidden until damage has already started. Common warning signs include:
- A high water bill from leak activity, even when usage hasn’t changed
- Mold or mildew growth without an obvious cause
- Unexplained wet spots on the wall or ceiling
- The sound of running water when fixtures aren’t in use
- A persistent musty smell in your house, especially near bathrooms or basements
These symptoms often point to a hidden or slow leak in your pipes that needs a pro to find and fix it.
Plumbing Leak Detection
Finding the exact source of a leak is the most important step. Fosh works with dedicated partners who use specialized tools for water leak detection, allowing them to find leaks behind walls, under floors, or under concrete.
Whether you’re dealing with a pinhole leak or mysterious ongoing moisture issues, the leak detection process is fast and accurate, so your repairs are, too.
Slab Leak Detection
Some of the most serious plumbing leaks occur beneath the concrete foundation of a home. These slab leaks can lead to structural damage if left untreated.
Signs that you may have a leak under your home include unexplained warm spots on the floor, cracks in the flooring, persistent moisture, or a sudden spike in your water bill.

Once the leak is found, fast repair is essential. Our team will work with partners to provide dependable leaky pipe repair to stop the problem at its source.
It’s important to spot the underlying issue to help prevent future damage and recurring repairs. Every solution is tailored to your home’s plumbing system and long-term reliability.

How Leak Detection Works: Answers to Common Plumbing Leak Questions
How can I tell if I have a hidden water leak?
Unexplained increases in your water bill, damp walls or ceilings, musty odors, or the sound of running water when fixtures aren’t in use are common signs of a hidden leak.
Will leak detection require opening walls or floors?
Usually not. Modern leak detection tools allow plumbers to locate leaks accurately with minimal disruption, so repairs stay targeted and efficient.
What causes plumbing leaks in homes?
Leaks are often caused by aging pipes, corrosion, shifting foundations, high water pressure, or worn connections, especially in older homes.
A slab leak occurs in pipes beneath your home’s concrete foundation. These leaks can cause structural damage if left untreated and should be addressed as soon as possible.
Can leaks affect my drains or water heater?
Yes. Undetected leaks can contribute to slow drains, backups, or corrosion that impacts appliances. In some cases, professional drain cleaning may be recommended as part of a long-term plumbing solution.
