How Sewer Backups Can Ruin Your Home's Foundation

When a sewer backs up, water can seep into the soil around your home. The ground becomes oversaturated, and the weight of the water pushes against your foundation walls. Over time, this pressure can cause cracks, bowing, or even shifting of the foundation.

The contaminants in sewage also change the soil chemistry, which can accelerate corrosion of any metal components in your foundation. If the water sits for long, the structural integrity of your home is at risk. You need to address the moisture quickly to prevent long-term issues.

First, stop using water in your home to avoid adding more volume to the system. Then, if it's safe, shut off the main water valve. Do not enter a flooded area if you suspect electrical hazards. Call a professional for help if needed.

You should also document the damage for your insurance records. Take photos of the affected areas before any cleanup begins. This record can be useful later, even though policies vary, and your insurer decides what is covered.

Regular maintenance of your sewer line can help prevent future backups. Avoid flushing items that clog pipes, and consider installing a backwater valve. In a humid subtropical climate with hot summers and spring hail and thunderstorms, heavy rain can overwhelm the system, so keep gutters clear.

If you live in Frisco, know where your main shutoff valve is and keep the area around your sewer cleanout accessible. For extra protection, you can have a plumber inspect your sewer line periodically. This simple step can save you from a major mess.
