If you’ve lived in Charleston for a summer or two, you already know that the humidity here is on a whole different level. With the air feeling thick most of the year (especially from May through September), that moisture doesn’t just make you sweat; it can also affect your plumbing. Whether you’re living downtown, out on James Island, or tucked away in Mount Pleasant, that sticky Lowcountry air could be quietly affecting your pipes.
Increased Risk of Pipe Corrosion
When warm, humid air wraps around cool metal pipes, it creates condensation, kind of like the way your glass sweats on a hot day. Over time, that moisture begins to wear down your pipes, especially if they are older and made from galvanized steel or copper. And once rust starts forming, leaks usually aren’t far behind.
Ways to Prevent It
To keep this from happening, try insulating pipes in cooler areas like the basement, garage, or crawlspace. Good ventilation is also key; more airflow means less trapped moisture. And if your home’s been around a while, go ahead and schedule a quick pipe inspection. Catching and fixing or replacing pipes with damage or rust early on can save you from bigger headaches later.
Mold and Mildew Around Plumbing Fixtures
Bathrooms, laundry rooms, and kitchen sinks are prime real estate for mold and mildew, especially in the summer. All that damp air and the occasional hidden drip make it easy for spores to grow.
Common Signs
Some things to watch out for: musty smells, dark spots on walls or cabinets, and paint that bubbles or peels. Those are usually signs there’s moisture hiding where it shouldn’t be.
Local Tip
Charleston homes, especially older ones, tend to trap humidity. If your bathroom doesn’t have a fan or a window, adding ventilation can go a long way toward keeping things dry and mold-free.
Pipe Expansion and Contraction
Humidity isn’t just annoying, it can actually cause your pipes to move. When it’s hot during the day and cooler at night (which happens a lot around here), your pipes can expand and contract. Over time, that back-and-forth can weaken the joints and connections, eventually leading to leaks or even bursts.
Our Tip
A seasonal inspection before summer gets into full swing can help spot any weak spots. It’s a quick check, but it can really save you from water damage down the line.
Sewer Line Trouble After Storms
And let’s not forget about Charleston’s summer storms. When it pours, that rainwater can soak into the ground and sneak into old or cracked sewer lines, something we see a lot in the historic parts of town.
Potential Issues
- Bad smells coming from your drains
- Sinks, tubs, or toilets that start draining slower than usual
- Backups or wet spots in your yard
Charleston-Specific Risks
With our high water table and clay-heavy soil, flooding and sewer issues are more common than you might think, especially in areas like West Ashley, James Island, and downtown. If you live in a flood-prone zone, it’s worth scheduling a sewer line check each year, just to be safe. Also make sure your sump pump is working well to protect your basement or crawl space from damage.
More Water Usage in the Summer
Summertime means more than just heat; it usually means higher water bills, too. Between extra showers, yard work, sprinklers, and filling up the kiddie pool, your plumbing gets a serious workout.
Appliances Most Affected
- Your water heater (which may be working overtime)
- Dishwashers and washing machines
- Outdoor hose bibs and irrigation systems
Bonus Tip
Check your water pressure while you’re at it. If it’s too high, it could be putting stress on your pipes. A pressure regulator can help keep things steady, especially when the city water supply is under summer demand.
Hidden Leaks Go Unnoticed
And here’s the thing: humidity can make it harder to tell if something’s leaking. When everything already feels a little damp, you might miss the signs.
Signs of a Hidden Leak
Hidden leaks often show up as higher-than-normal water bills, warped or soft spots on the walls or floors, or that telltale musty smell that just won’t go away. If you notice any of these, don’t ignore them — it could mean there’s water pooling where you can’t see it.
