Bad Smell from Drains? Find & Fix Sewer Odors
Eliminate foul odors caused by dry traps, bacteria, or sewer gas – we diagnose and solve the root problem.
Why Do My Drains Smell?
Foul odors from sinks, showers, or floor drains are not just unpleasant – they can indicate a serious plumbing issue. Common culprits include a dried‑out P‑trap, bacterial growth, a broken sewer line, or a clogged vent pipe. Our team uses advanced camera inspections and smoke testing to find the exact source and eliminate the smell permanently.
Common Signs of Drain Odor Problems
- Rotten egg (sulfur) smell from sinks or tubs
- Musty or sewage‑like odor that worsens after rain
- Smell coming from rarely used bathrooms or basements
- Odor stronger when running water or flushing toilet
- Smell accompanied by slow drains or gurgling sounds
Our Professional Approach
Camera Inspection
We insert a high‑definition camera into your drain line to check for cracks, blockages, or dry traps.
Smoke Testing
For vent or sewer gas leaks, we use safe, non‑toxic smoke to pinpoint the exact entry point.
Professional Cleaning
We remove biofilm, grease, and debris using hydro jetting or snaking – eliminating bacterial growth.
Repair or Replace
If a broken pipe or damaged vent is the cause, we provide code‑compliant repair or replacement.
How to Prevent Drain Odors
- Run water in unused sinks/tubs weekly to keep P‑traps full
- Avoid pouring grease or oil down the drain
- Use enzyme‑based drain cleaners monthly (not harsh chemicals)
- Schedule professional drain cleaning every 1‑2 years
- Ensure your roof vent pipes are not blocked by leaves or nests

Frequently Asked Questions – Drain Odors
Is a rotten egg smell dangerous?
Yes, treat it with caution. If the smell resembles natural gas, leave the area and call 911 immediately. If it is sewer gas from your drains, it contains hydrogen sulfide and methane, which can be hazardous in high concentrations. Ventilate the area and schedule a plumbing repair to fix the underlying issue.
Why does the smell come only after rain?
Heavy rain can overwhelm the municipal sewer system, causing pressure changes (surcharging) that push sewer gases back up through your drains. It can also expose cracks in underground sewer lines or indicate a blocked roof vent pipe that isn't allowing gas to escape properly.
Can I fix a dry P‑trap myself?
Yes – simply run water for 30 seconds in the affected sink/tub. If the odor disappears, you only need to use that fixture more often. If it returns, call us – there may be a deeper issue.
How much does odor inspection cost?
We provide written estimates for most odor problems. Camera or smoke testing fees apply if needed, but we always inform you before any charges.
