Eliminate Unwanted Odors with Proper Residential Sewer Maintenance

Got a Bad Smell in Your Home? It Could Be Your Sewer

At Polar Plumbing, Heating, & Air Conditioning, one of the most common questions we get from O’Fallon IL homeowners is: “Why does my house smell like a sewer?”

The answer is usually simple — your sewer system needs attention.

Unpleasant odors from drains, bathrooms, or basements are more than just a nuisance. They’re often a warning sign that something’s wrong with your plumbing or sewer lines. In this post, I’ll explain what causes sewer odors and how proper sewer maintenance can help you eliminate them for good.

What Causes Sewer Odors in Homes?

Dry P-Traps

The P-trap is the curved pipe under your sink or drain. It holds water that acts as a barrier to prevent sewer gases from entering your home.

When drains aren’t used regularly — like in guest bathrooms or basement showers — the water can evaporate, allowing smells to come through.

Damaged or Cracked Sewer Pipes

Cracks in underground pipes can leak gas into your home or yard. You may notice:

  • Odors near foundation vents
  • Patches of lush grass (from leaking sewage)
  • Persistent smells inside even after cleaning drains

Why Sewer Odors Shouldn’t Be Ignored

Sewer gas isn’t just unpleasant — it can be dangerous. Prolonged exposure to hydrogen sulfide can cause:

  • Headaches
  • Nausea
  • Fatigue
  • Irritation to eyes and throat

Even small leaks can reduce your indoor air quality and signal serious problems in your plumbing system.

How Polar Plumbing Solves Sewer Odor Problems

We specialize in residential sewer maintenance and odor elimination throughout O’Fallon IL. Our proven approach includes:

Step 1 — Sewer Camera Inspection

We begin with a video sewer inspection to locate:

  • Blockages
  • Cracks
  • Tree root intrusion
  • Pipe misalignment

This gives us a full picture of your system and helps us recommend the right fix.

Step 2 — Sewer Line Cleaning

We use hydro jetting to clear buildup and remove clogs deep in your sewer lines. It’s powerful, safe for your pipes, and highly effective at removing grease, soap scum, and debris.

Step 3 — Repair or Replace Damaged Sections

If we discover broken or deteriorating pipes, we provide expert sewer repair and pipe replacement using trenchless or traditional methods, depending on what’s best for your home.

Step 4 — Trap & Vent System Checks

We also check your home’s P-traps and venting system to make sure gases are being safely redirected out of your home and that drains are properly sealed.

Sewer Maintenance Tips to Prevent Odors

You can help keep your sewer system in good shape year-round by following these tips:

Run Water in Infrequently Used Drains

Once a week, run water in basement floor drains, guest bathroom sinks, or unused showers to keep P-traps full

Avoid Chemical Drain Cleaners

Harsh chemicals can erode pipes and damage traps. Instead, use enzyme-based cleaners or call for professional drain cleaning.

Watch for Early Signs

Don’t ignore:

  • Gurgling noises
  • Bubbles in the toilet
  • Odors after storms

These may signal a sewer problem brewing under the surface.

Schedule Annual Sewer Maintenance

Annual inspections and cleaning can catch issues before they become emergencies. It’s especially important if your home is:

  • Over 20 years old
  • Surrounded by large trees
  • On a septic-to-sewer conversion
