Sewer odor diagnosis

That sewer smell isn't normal — and it won't fix itself.

A faint whiff in the bathroom, a stronger blast from the basement, or a "rotten egg" smell when the furnace kicks on — sewer odor can make your home feel embarrassing, unsafe, and stressful to be in.

Dry floor drains or traps letting sewer gas drift straight into living spaces.
Cracked or broken vent piping hidden in walls or ceilings.
Loose toilet seals or unsealed cleanouts leaking sewer gas.
Damaged or offset sewer lines under the slab or yard.

What to expect

Our step-by-step sewer odor diagnosis process.

We follow a consistent, code-minded process so we don't just cover up the smell — we find and fix the root cause.

1. Listen & Locate — We map out when and where you notice the odor, then walk the property with you.
2. Inspect & Test — We check traps, drains, toilets, vents, and exposed sewer piping for obvious issues.
3. Camera Inspection — If needed, we send a camera through the main line to look for breaks, offsets, or root intrusion.
4. Smoke Testing — We safely fill the system with non-toxic smoke to reveal hidden leaks behind walls or under slabs.
5. Options & Plan — We show you what we found, walk through repair options, and help you prioritize next steps and budget.

Transparent pricing & long-term peace of mind.

Every home is different, so we tailor the visit to your situation — sometimes the fix is as simple as restoring a trap, sometimes it requires a larger repair.

Upfront pricing before we start any work — no surprises on the invoice.
Clear separation between diagnosis-only visits and larger repair projects.
Photo and video documentation of what we find, so you can see the problem yourself.
Financing options available for larger repair or replacement work — ask your technician.

Questions, answered

Sewer odor diagnosis FAQs.

Here are answers to some of the most common questions homeowners ask us about sewer smells and sewer gas in their homes.

Is sewer gas in my home dangerous?

Mild sewer odor is usually more of a comfort issue than an emergency, but strong, constant, or worsening smells can be unhealthy — especially in enclosed areas like basements or utility rooms. If the odor is intense or anyone in the home is feeling sick, call a professional quickly and ventilate the area if you can do so safely.

Why does my house smell like sewer only sometimes?

Intermittent sewer odors often point to dry traps, venting problems, or small leaks that only open under certain conditions — like heavy rain, multiple fixtures running at once, or when exhaust fans are pulling air from the home. Our diagnosis visit is designed to recreate those conditions so we can see what is really happening.

How do you find where the sewer odor is coming from?

We combine interviews, visual inspections, and testing. After checking traps and fixtures, we may use a drain camera to inspect buried lines and a non-toxic smoke machine to gently pressurize the system. Wherever the smoke comes out, sewer gas can escape too — that is how we pinpoint leaks you cannot see.

Does sewer odor always mean a broken sewer line?

No. Many sewer odors come from simpler issues like dry floor drains, bad toilet wax rings, or open cleanouts. When we do find main line damage, we will show you camera footage and give you options ranging from spot repair to full replacement, along with the pros and cons of each.

What should I do before your sewer odor appointment?

Try to note when the smell is strongest and where you notice it most. Avoid masking the odor with heavy fragrances right before we arrive — that makes it harder to track down. If we plan a smoke test, we may ask you to temporarily shut off certain fans or HVAC equipment so we can clearly see any smoke escapes.
