How to Winterize Your Drains Before Cold Weather

As temperatures drop, residential plumbing becomes more vulnerable to freezing, blockages, and drainage issues. Winterizing your drains early can reduce the risk of backup problems and keep sinks, tubs, and toilets flowing smoothly through the cold season.

Why winterizing matters

When water can’t move freely, it tends to linger in pipes—especially in slower drains or vulnerable sections of plumbing. In freezing temperatures, trapped water may expand, contributing to pipe damage. Meanwhile, colder conditions can worsen existing buildup from grease, soap scum, hair, and debris, leading to stubborn clogs.
