Sewer leak and sewer gas detection in Littleton, CO
Pinpointing hidden underground sewer leaks, fractured vent stacks, and dangerous sewer gas infiltration using cameras and smoke testing.
Overview & Littleton field reality
A sewer leak doesn't always cause an immediate backup. Often, it begins as a mysterious rotten egg smell inside your home, an unexplainable soggy patch on your lawn, or a crack forming in your basement foundation. Sewer gas contains toxic hydrogen sulfide and methane that should never enter living spaces. We trace leaks and odor breaches to their exact source using electronic sniffers, smoke testing, and camera inspection.
What our sewer leak and sewer gas detection in littleton, co includes
Our sewer leak and sewer gas detection service pinpoints hidden drainage breaks, sub-slab cracks, fractured roof vent stacks, and dangerous sewer gas infiltration. Using electronic vapor sniffers, non-toxic pressurized smoke testing, and CCTV pipe inspection, we identify the exact source of odors and water seepage without invasive tearing into finished drywall or landscaping.
Signs your sewer line needs attention
- Persistent rotten egg or sulfur odors in basements, bathrooms, or crawlspaces
- Lush, abnormally green, or perpetually damp patches of grass in the yard
- Unexplained settlement or foundation cracking near the sewer line exit wall
- Gurgling sounds in drain traps or toilets that mysteriously lose their water seal
- Mold or moisture accumulation along basement walls or sub-slab areas
Why this failure occurs in Front Range soils
Cracked roof vent stacks caused by Front Range freeze-thaw cycles or high winds
Underground clay pipe joint separations allowing wastewater to seep into foundation backfill
Dry or failed plumbing trap seals in basement floor drains or seldom-used fixtures
Unsealed or improperly vented cleanout plugs inside mechanical rooms
Our diagnostic protocol
- 1Non-toxic artificial smoke testing blown through the sewer system to visually trace vapor leaks through walls, floors, and soil
- 2Electronic hydrogen sulfide gas sniffers to detect volatile organic sewer gases down to parts-per-million levels
- 3Fiber-optic camera scoping through vent stacks and cleanouts to verify pipe wall integrity
Treatment options & engineering trade-offs
Smoke Testing & Vent Stack Repair
Pumping non-toxic smoke into the drainage network to find roof vent cracks, dry trap seals, and unsealed cleanout caps.
Underground Electronic Leak Isolation
Using inflatable test plugs to pressure-test individual pipe sections and isolate sub-surface leaks.

Step-by-step repair methodology
Initial Gas Sniffer & Odor Survey
We test indoor air around floor drains, mechanical rooms, and fixture traps using electronic combustible gas detectors.
Drain Trap & Seal Verification
We inspect all basement floor drain traps, primer lines, wax rings on toilets, and cleanout cap seals.
Non-Toxic Smoke Testing
A smoke generator pumps white, odorless, non-toxic smoke through the sewer cleanout. Any crack in a vent stack or drain immediately reveals itself.
Camera Inspection of Identified Breaches
We feed a camera to examine the internal condition of the leaking pipe or vent stack identified during smoke testing.
Targeted Repair & Re-Testing
We repair the broken vent, seal the damaged pipe, or replace the trap seal, then re-test air quality to confirm zero gas infiltration.
Cost factors for this repair
- •Complexity of the home plumbing layout (single-story ranch vs. multi-story home with multiple vent stacks)
- •Location of the leak (accessible basement pipe vs. buried underground lateral vs. inside drywall chase)
- •Need for sub-slab excavation or rooftop vent stack rebuilding
Restoration & prevention
Smoke dissipates naturally in minutes with standard ventilation. Minor wall or drywall access points are sealed.
Local municipal rules & permit compliance
In the City of Littleton and throughout Arapahoe and Jefferson counties, the International Plumbing Code (IPC) and International Residential Code (IRC) mandate that all plumbing fixtures maintain a liquid trap seal of not less than 2 inches and not more than 4 inches to prevent sewer gas infiltration into habitable spaces. Under local health department regulations and CDPHE standards, unresolved sewer gas leaks containing toxic hydrogen sulfide and explosive methane represent an immediate sanitation violation. Any required vent pipe alterations or drain line repairs must be performed by a licensed plumbing contractor in compliance with City of Littleton building codes and inspected prior to concealment.
