Cheyenne’s cold semi-arid winters send ground temperatures low enough to stiffen grease and expand older clay or cast-iron mains under streets in the Historic District and Capitol Hill. When those lines already carry decades of scale and minor offsets, a single heavy rain or holiday cooking surge is often enough to back waste into basements. Technicians start every job by locating the cleanout, then run a camera to map the exact distance to the city tap before any water or cable enters the line.
Laramie County soil shifts with freeze-thaw cycles, so mains serving 1950s–1970s houses in Sunnyside and East Cheyenne frequently develop bellies that trap solids. Hydro jetting at 3,500–4,000 psi removes the buildup without fracturing brittle pipe, but the operator must watch pressure at every joint and finish with a final camera pass to confirm the line now carries full flow to the main. Homes near the Cheyenne Botanic Gardens sit on slightly higher ground, yet their laterals still cross old tree roots from boulevard plantings that reach twenty feet to the sewer.
Nearby towns such as Burns and Carpenter share the same county water table and winter conditions, so crews keep jetter reels and sectional machines staged for same-day response when a line freezes or a root mass lets go. Access is often limited to side-yard cleanouts set flush with the lawn, requiring hand digging through frozen sod before the machine can be attached.
Technician insight
In Cheyenne the thing that catches most people out with Main Sewer Line Cleaning is the combination of old clay pipe and deep winter freezes; a line that ran fine all summer can ice up or shift just enough in January to trap grease from a single holiday meal, and the cleanout is often buried under two feet of snow in North Cheyenne yards.
South Cheyenne main line backup after heavy snowmelt
Waste backed up through the basement floor drain after a week of above-freezing temperatures. Camera showed a root mass and belly 48 ft from the cleanout. Tech cut the roots, jetted the line, and verified full flow to the city tap with a second camera pass.
Main Sewer Line Cleaning Services We Offer
✓Hydro Jetting Main Sewer Lines
High-pressure water scours roots, grease and mineral scale from the full diameter of the main without chemicals that could harm Laramie County septic systems.
✓Video Camera Inspection
A waterproof camera travels the entire main from the cleanout to the city tap, recording exact locations of offsets, root intrusions and standing water in older Capitol Hill and Sunnyside lines.
✓Root Cutting and Removal
Motorized cutting heads slice through tree roots that have entered joints in South Cheyenne and West Cheyenne laterals, followed by jetting to flush debris to the main.
✓Grease and Sludge Clearing
Specialized jetter nozzles and chain knockers break up cooking grease and sludge that accumulate in mains serving restaurants and multi-unit buildings near the Cheyenne Depot Museum.
✓Emergency Main Line Unclogging
Same-day response for complete blockages that back waste into basements, available during business hours from the shop at 1792 E Allison Rd.

How it works
- 1
Locate And Expose Cleanout
Crew confirms the cleanout location, often in the front or side yard of homes in North Cheyenne or Lakeview, then clears snow or sod as needed.
- 2
Camera Survey
A recording camera is pushed from the cleanout to the city connection, mapping every defect before any cleaning begins.
- 3
Select And Apply Cleaning Method
Depending on findings, the tech chooses hydro jetting, root cutting or sectional cable to restore flow without damaging pipe.
- 4
Final Verification And Flush
A second camera pass confirms the line is clear, then water is run from multiple fixtures to verify drainage.
Pricing
Most main line jobs in Cheyenne fall between a few hundred dollars for routine jetting and higher when excavation or multiple visits are required.
