Older Bay Area homes may experience hidden water leaks caused by aging plumbing systems, shifting soil, and hard water. Luckily, professional leak detection and routine plumbing inspections by a skilled plumber can help homeowners catch problems early and save money on costly repairs.
Explore common causes of water leaks, how to spot a hidden leak, and leak prevention tips to keep your Bay Area home safe from hidden water leaks.
The Bay Area is full of beautiful older homes, but these architectural creations often come with outdated plumbing systems. Pipes made from galvanized steel, cast iron, or copper are prone to corrosion over time, which can lead to hidden water leaks in walls, floors, and ceilings.
The climate and grounds of the Bay Area also pose challenges, with shifting soils leading to foundation stress that can impact your plumbing. Many parts of the Bay Area have hard water, and the mineral build-up can increase corrosion inside your pipes.
From home plumbing issues to Bay Area soil, there are plenty of factors that can cause plumbing leaks in old homes.
As your plumbing ages, mineral build-up and rust naturally lead to pipe corrosion in older homes. Many older Bay Area homes use cast-iron or galvanized steel pipes that have exceeded their lifespan and are even more likely to leak. Since these pipes run all through your home, it’s common to see leaks behind walls or under floors.
Issues with your plumbing when it was first installed or repaired often show up in the soldering and pipe connections. Joints and pipes under high tension may be more prone to leaking.
The Bay Area sits on a fault line, which means the soil and landscape are prone to tiny shifts that you may not even notice. However, your home will feel them. As soils move over time, they put pressure on various parts of your home, including your plumbing. If this pressure becomes too high, leaky or burst pipes can occur anywhere in your home.
Common household appliances like water heaters, dishwashers, and laundry machines can sometimes break, leading to hidden leaks. This can also be an issue for HVAC components like air conditioners, which require condensate lines to get rid of excess water. If one of these water lines breaks or leaks, water can build up inside your walls or floors.
Common plumbing problems, such as high water pressure or clogs, can affect your home. If a clog travels or gets stuck in the pipes in your walls or floors, it can lead to a leak or burst pipe in unexpected places.

While chemical cleaners may make the job go quicker, they take a long-term toll on your plumbing. Harsh chemicals increase corrosion in your pipes, increasing the risk of leaks. Instead, opt for gentle cleaning solutions like baking soda, vinegar, and hot water.
Take care of your plumbing by flushing only waste and toilet paper, and avoid flushing items like wipes or personal items. If you have a garbage disposal, avoid bones, avocado pits, oils, grease, fats, and fibrous items like corn husks that frequently cause clogs.
If your home is prone to clogs and other plumbing challenges, professional drain cleaning can be the best way to keep things running properly. Scheduling drain cleaning every 12 to 18 months takes care of issues like clogs without putting any excess strain on your plumbing (and helps get the tough clogs you can’t reach with DIY methods).
Your plumbing inspector can assess the condition of your pipes and advise you on the best care options. In some cases, routine maintenance is enough to keep everything flowing smoothly for a while. However, if you have old pipes, such as galvanized steel or cast iron nearing the end of their expected lifespan, it may be time to consider a full home repiping to reduce the risk of widespread leaks.
If you suspect a leak in your home, the best way to resolve the issue is to call for professional water leak detection. A licensed plumber can use tools like moisture meters and thermal cameras to detect the leak without impacting your home any more than necessary.
Professional leak detection is key to detecting leaks as quickly and efficiently as possible. Without prompt water leak repair, hidden leaks can quickly lead to widespread water damage that impacts your plumbing, walls, furniture, and the structural integrity of your home. Even slow leaks can cause mold, electrical issues, and rising water costs.
