Top 5 Causes of Winter Sewer Clogs

1. Winter Storms

While snow is the most obvious winter weather concern, heavy rainstorms can also overwhelm your sewer system. Debris blocking storm drains or sewers can prevent proper drainage, causing backups into homes.

2. Tree Roots

Dormant or not, tree roots remain a common culprit in sewer clogs. Roots penetrate sewer lines in search of water and nutrients, trapping debris over time. In winter, these blockages can worsen as cold temperatures slow water flow.

3. Sagging Sewer Lines

Sagging occurs when sections of sewer pipes sink due to poor installation or shifting soil. These low points collect debris, increasing the risk of clogs—especially during freezing weather when water flow is slowed.

4. Soil Disturbances

Soil changes from freezing, thawing, or construction can disrupt sewer pipes. Frost heave, shifting ground, or heavy machinery can crack, bend, or rupture pipes, creating blockages or other costly problems.

5. Improper Disposal

Winter brings holidays, gatherings, and heavy kitchen use. Improper disposal of grease, fats, and food waste can solidify in cold weather, creating stubborn sewer clogs.


Signs You Have a Winter Sewer Clog

Watch for these signs to catch a clog early:

  • Multiple Fixtures Clogging: When several drains back up at once, the problem is likely in the main sewer line.

  • Water Backups: Toilets, showers, or sinks backing up during use in other areas indicate a blockage.

  • Slow Draining: Partial clogs cause slow drainage, which can escalate into full blockages if left unaddressed.


Why Quick Action Matters

Winter sewer clogs can worsen quickly in freezing temperatures, increasing the risk of water damage and expensive repairs. Prompt intervention is key.
