How Seasonal Changes Affect Underground Plumbing
Braving a St. Louis winter could earn just about anyone a trophy. If you managed to commute on Highway 141 without getting stuck in traffic, or worse, stranded in the snow, you can safely say you conquered the season. But just as winter fades into the rearview mirror, a new set of challenges begins to surface. Spring is right around the corner, and that’s when underground plumbing issues tend to show up the most. While these problems can happen at any time of year, the transition from freezing temperatures to thawing ground puts extra stress on your pipes. During the winter, the ground freezes and expands, putting pressure on your plumbing lines. At the same time, the pipes themselves contract in the cold, which can create small cracks or weaken already vulnerable areas. These issues often go unnoticed because everything is essentially “locked in place” by the frozen soil.
As temperatures rise and the ground begins to thaw, that stability disappears. The soil softens, shifts, and sometimes even settles unevenly, which can cause pipes to move or sag. This movement puts strain on joints and any weak spots that developed over the winter, turning minor damage into more serious leaks or breaks. On top of that, melting snow and early spring rains add extra moisture to the ground, increasing pressure around your sewer and water lines. If there are any cracks or openings, water can seep in, or wastewater can leak out.
This combination of ground movement, added pressure, and hidden winter damage is exactly why early spring is such a common time for underground plumbing problems to surface. What started as a small, unnoticed issue during the colder months can quickly become a visible and costly problem once everything begins to thaw and shift.
We “Show-Me State” residents aren’t home free yet when it comes to underground plumbing issues. In the summer, dry conditions and shifting soil can cause even more problems to arise, keeping homeowners on their toes year-round.
In the summer, when the soil loses moisture, it contracts and shrinks, creating gaps around your pipes. This can cause them to shift slightly, misalign, or even sag over time. Even small movements may not seem like a big deal at first, but over weeks or months, these tiny shifts can stress pipe joints, loosen fittings, and widen existing cracks that set the stage for leaks or blockages down the line.
Another major factor in the warmer months is tree roots. Yes, we all love our Maple trees and our Sycamore trees, but as these trees grow, their roots actively search for water, and underground pipes can be an attractive target. Even the smallest crack or loose joint in your plumbing system can become an entry point for roots, which then expand inside the pipes and cause clogs, breaks, or even complete blockages.
At Barth Company Sewer & Water, everyone on our team is local and well-acquainted with the challenges that seasonal changes can bring to underground plumbing. But just because the seasons shift doesn’t mean they have to cause problems for you. We have the knowledge and experience to repair or replace any issues caused by weather, soil movement, or seasonal stress. And while we love Missouri’s trees, we even have some at our office. However, we definitely don’t love them growing into your pipes.
The weather in Missouri can be intense, but your plumbing problems don’t have to be. Being aware of the signs and ready to call a professional when something seems off is the best way to protect your home and avoid costly damage.
