Did you know that a hidden plumbing leak can go undetected for weeks, months, or even years? That’s right, and during that time, it can lead to significant water damage, mold growth, and even structural damage to your home or business. But, how can you tell if you have a hidden leak? Well, in this blog post, I’m going to share with you some of the signs to look out for. By spotting trouble early, you can save yourself time, money, and hassle down the line.

Increased water bill

If you notice a significant increase in your water bill, it’s a sign that something is wrong. But, before you assume the worst, make sure you haven’t started any new irrigation, added a pool, or have guests staying with you. If you can’t explain the increase, it’s time to call a plumber.

Damp spots

Damp or wet spots on your walls, ceilings, or floor is a clear indicator of a hidden leak. These can be caused by a variety of issues, such as a burst pipe, loose connection, or leaking appliance. If you notice damp spots, it’s essential to have them inspected as soon as possible to prevent further damage.

Mold growth

Mold thrives in warm, moist environments, which makes hidden leaks the perfect breeding ground. If you notice any mold growth, it’s a sign that you not only have a leak but it’s been there long enough for mold to grow. Not only is mold unsightly, but it can also pose a health risk to you and your family.

Musty smell

Do you notice a musty, damp smell in your home or business? If so, it’s a sign of hidden moisture, which is often caused by a leak. This smell can be hard to locate, so pay attention to where it seems the strongest. Once you know where it’s coming from, call a plumber right away.

Low water pressure

Low water pressure can have several causes, one of which is a hidden leak. If you’re experiencing low water pressure, it’s a sign that something isn’t right and should be checked by a professional.


Ignoring the signs of a hidden leak can lead to major water damage, costly repairs, and even jeopardize the health and safety of your family or customers. However, by keeping an eye out for increased water bills, damp spots, mold growth, musty smells, and low water pressure, you can spot trouble early and save yourself a lot of headaches. If you notice any of these signs, call a licensed and experienced plumber, like us here at XYZ Plumbing, to help you identify and fix the leak. Remember, a little preventative action now can go a long way in lowering your stress levels and keeping your property safe and sound.
