🚨 Five Signs You Need a Plumber in Andover, MN

Plumbing issues don’t go away on their own—and waiting too long can lead to costly water damage, mold, or even structural problems. At Thelen Plumbing, Heating, and Air, we help Andover homeowners catch and fix issues early with fast, expert service. Here are five common red flags that it’s time to call in the pros:

1. Low Water Pressure

If your faucets or shower suddenly feel weak, it could mean mineral buildup, pipe leaks, or a hidden blockage. Our licensed plumbers can quickly diagnose whether it’s an isolated fixture issue or a sign of a bigger problem—and get your pressure back to normal.

2. Slow-Draining Sinks or Tubs

Water pooling in your sinks or tubs often points to clogs caused by hair, grease, or soap scum. While DIY tools might help temporarily, recurring slow drains usually mean a deeper blockage. We use professional-grade equipment to clear clogs safely and restore full flow.

3. Foul Smells from Drains

Sewer-like odors or musty smells from your plumbing system could indicate a dry P-trap, broken vent pipe, or even a cracked sewer line. Our team can inspect your system and resolve the issue before it turns into a health hazard or a bigger mess.

4. Water Stains or Discoloration

Spots on your walls, ceilings, or floors often mean there’s a hidden leak behind them. These slow leaks can rot wood, grow mold, and rack up repair bills fast. We use leak detection tools to find and fix problems before they spread.

5. Noisy Pipes

Banging, whistling, or rattling pipes are not just annoying—they may signal loose fittings, trapped air, or high water pressure. We’ll identify the source and provide a fix that protects your plumbing and your peace of mind.
