5 Signs of a Water Leak in Your Home

Published by Point Loma Electric, Plumbing, Heating & Air

Water leaks in your home can cause significant damage if left untreated. But sometimes, the signs of a water leak in your home can be subtle. Knowing how to tell if you have a water leak is essential for every homeowner. Let’s go over the top five signs to look out for in more detail below.

Unexpected Spike in Your Water Bill

One of the most common signs of a water leak in your home is a sudden increase in your water bill. While variations in water usage can occur, especially if you’ve recently used your washing machine more than usual or have had guests over, an unexpected spike might indicate a hidden water leak.

Tip: Monitor your water bill closely. If your water usage seems unusually high without a clear reason, this could be an indication of a leak somewhere in your home.

Hearing Unusual Sounds

Do you hear water running when no taps are on? This unusual noise can be a clear sign of a water leak. Sometimes, even if there’s a leak somewhere in your plumbing systems, it might not be visible immediately. But you may hear water moving, dripping, or rushing inside walls or under the floor.

Tip: Learning how to tell if you have a water leak is only the beginning. You’ll want to put what you’ve learned into action. Periodically turn off all appliances that use water, and listen carefully. If you hear water, it’s time to call a plumber.

Musty Smells and Mold Growth

A persistent musty smell is not just unpleasant; it can indicate a water leak in your home. The presence of mold and mildew — especially in places where it shouldn’t typically be — suggests that there’s excess moisture. This might be due to a leak somewhere that’s causing wet spots, creating a breeding ground for mold.

Tip: Regularly inspect hidden corners, basements, and behind furniture for signs of mold and mildew. Any unexpected musty smell should be a red flag.

Unexplained Wet Spots

Are you still wondering how to tell if you have a water leak? Well, not all signs of a leak in your home are hidden. Sometimes, you’ll see wet spots on the floor, walls, or ceiling. This is a direct indication that there’s a water leak somewhere nearby. Whether it’s a minor leak or a significant burst, it’s essential to address it immediately to prevent further damage to your home.

Tip: If you find any wet spots, check the closest water supply, appliances like the washing machine, or your plumbing systems for the source of the leak.

Fluctuating Water Pressure

Have you noticed that your water pressure is not consistent? Fluctuations in water pressure can be a sign of a water leak in your home. When there’s a breach in your water supply system, it can reduce the water pressure in certain areas or throughout your house.

Tip: Keep an eye on your water meter. If it’s running even when all water sources are off, there’s likely a leak in your system.

I am very pleased with this company because they have great people working for them. [My technician] was organized and all were at the house in 2 days. Paper booties were worn. The electricians knew what they were doing and produce excellent work. I had 3 new circuits put in along with updating box. All this was done in one day. This co also sends a pix of technician who is coming to your house. Every person had lovely manners, and cleaned up, even vacuumed under stove when it was moved. A fine experience and I’d use them again.

I had a water leak at my house and its cause was extremely difficult to find. Our tech spent a long time carefully analyzing and testing all possible options until he found the cause of the leak, like really a true detective, that nobody else before him was able to find. He demonstrated not only that he is a truly top professional but the he also is kind, patient and understanding. He explained all the issues very well and was also mindful of my time and convenience. He works very fast, efficiently and reliably and is extremely nice human being.

Point Loma Electric and Plumbing did electrical work in our house once and we liked the service the first time so we called them again. The technicians have been nothing but friendly and professional both times. They walked us through every step of the process. They showed up on time and completed the work in a timely manner. If we had any concerns they made sure the address them, if anything was needed, they handled it. We will definitely use Point Loma Electric and Plumbing again. Johnny who oversaw the work is the best!! Thank you

Had an emergency water heater leak. Called Point Loma. Within the hour, James shows up and goes to work. And by the next day, we have a tankless water heater up and running. Thanks to James for the excellent customer attention, service and hard work!

Always great to work with them - years 2011 for new electrical panel, and 2025 for some minor upgrades. Erich and Leo corrected 3 problems with old wiring we were having. Very great team and very much appreciate their work.

My a/c has not been working for some time. I called Point Loma Electrical and they sent Nicholas Mullins to stop by and check it out. What a great guy. He was very respectful, honest, evaluated the situation and made recommendations that I felt were straight forward. This company is top notch and I would recommend them to any of my friends and family. This is now my go to ac repair company.

We had Point Loma Elec rewire our entire 62 year-old house's electric. They worked efficiently and were thorough letting us know what was discovered and done each day. Timely, neat, and responsive and affordable with great financing. Highly recommend.

This is a great team. I had to replace some fluorescent lights in the kitchen. I couldn't do it myself because the ballasts had to be replaced and that's above my skill level. Anthony and Matt came today and put in new led lights (with a 10 year warranty- fluorescent lights are ancient tech). Anthony and Matt were very professional and efficient. I would recommend them highly!
