How Do I Know If My Storm Drain Is Backing Up?

Check low spots in your yard after a storm. Standing water that lingers for hours or days often means the storm drain is blocked. Look for water seeping up through the ground or overflowing from the drain grate itself.

Another clue is a muddy or wet patch near the drain pipe outlet. If leaves, dirt, or roots have collected, water has nowhere to go. A sudden heavy rain can reveal a hidden blockage quickly, especially after a long dry spell.

• Water pooling over the grate
• Damp ground far from the drain
• Visible debris or roots in the opening
• A strong musty smell near the drain
• Slow drainage after rain stops

Storm drains clog when leaves, twigs, and trash build up in the pipe. Over time, roots from trees can grow into the drain and block the flow. In areas with heavy soil, the pipe can shift or crack, letting dirt in and water out.

Heavy rain can overwhelm an undersized or old drain system. If your home sits at the bottom of a slope, water may collect faster than the drain can handle. Knowing the cause helps you decide whether to clear the blockage or call for help.

If water enters your living space or you cannot clear the blockage, it's time to bring in local water damage pros. They have tools to inspect the drain and locate the obstruction. Acting fast can prevent costly damage to floors, walls, and belongings.

A professional can also check for hidden leaks or pipe damage. If your home has already taken on water, a cleanup service may be needed to dry everything properly. The cost depends on the extent of the blockage and the damage it caused, so it varies from one situation to the next.

• Water inside your home
• A persistent smell you cannot remove
• Multiple drains backing up at once
• Visible sagging or wet spots in the yard
• You suspect a broken pipe
