How to Price Drain Cleaning Jobs: A Flat, Hourly, and Per-Foot Formula
Drain cleaning pricing formula: flat, hourly, and per-foot methods with US benchmarks, cost drivers, and state examples for California, Texas, and Florida.
What to take away
- Typical US drain cleaning jobs run $150 to $350 flat for a standard clog, $75 to $150 per hour, or $3 to $7 per foot.
- California metro rates often run $120 to $180 per hour, Texas $80 to $130, and Florida $90 to $140.
- A quote should include a trip fee, a minimum charge, and a separate line for camera inspection when that tool is used.
- Sewer line work adds higher per-foot charges because of equipment weight, access, and permitting.
- Overtime, emergency nights, and confined space entry can push the final invoice 30% to 50% above the base.
A drain cleaning price is not a single number. Flat, hourly, and per foot are the three methods that matter, and the worked formula below builds a quote in minutes. Compare sample plumbing contractor quotes to see how a full invoice fits together.
What the range covers
The ranges below are illustrative, not a national survey. They come from contractor job postings, regional rate sheets, and trade group discussions. Use them as a starting point, then adjust for your local wage and truck costs.
Pricing Methods Compared
Flat rate
- Best for
- Predictable clog
- Range
- $150-$350
Hourly rate
- Best for
- Unknown pipe
- Range
- $75-$150
Per foot
- Best for
- Long sewer runs
- Range
- $3-$7
| Pricing method | Low to high range |
|---|---|
| Flat rate for a standard residential clog | $150 to $350 |
| Hourly rate, drain cleaning | $75 to $150 |
| Per foot, cable or jetting | $3 to $7 |
| Sewer camera inspection add-on | $100 to $300 |
A flat rate works best when the clog is predictable. An hourly rate fits jobs where the pipe condition is unknown. Per foot pricing suits long sewer runs and root cutting.
Line by line
An invoice for drain cleaning should not hide the real costs. Build it from these line items:
Invoice Line Items
- Trip or dispatch fee$50-$125
- Labor minimum1-2 hours
- Equipment chargesnake, jetter, camera
- Permit or inspection fee
- Disposal or materials charge
- Trip feecovers the truck roll, and many shops waive it when the customer approves the repair.
- Minimum chargethe smallest billable visit, usually one hour of labor or a set floor.
- Laborthe hourly rate applied to time on site, $75 to $150 in most US metros.
- Machine chargecable or jetter setup, priced by machine size and run length.
- Camera inspectiona separate $100 to $300 when the sewer line is scoped.
- Disposalsludge and debris hauling, billed per load or as a flat add-on.
This structure makes the price defensible. It also gives the customer a reason to approve add-ons like camera inspection before work begins. When a customer pushes back on a line item, a clear plumbing contractor complaint handling process prevents a small dispute from growing.
What moves the number
Three cost drivers do most of the work.
Line length and pipe diameter move the per-foot price. A 4-inch sewer main costs more per foot than a 2-inch branch because the cable is heavier and the machine must run longer.
Per-foot formula: (rate per foot x linear feet) + trip fee + machine charge = quote. A 60-foot mainline at $5 per foot is $300, plus a $75 trip fee and a $75 machine charge, or $450. The same run at $8 per foot is $480 before add-ons.
Access drives the largest swing. A cleanout at grade is cheap. A roof vent or a mainline under a basement slab requires more labor and sometimes a second person. Confined space entry can add permit and rescue costs, as OSHA's permit-required confined spaces standard explains.
Blockage type and depth matter. Grease and paper clear quickly, but roots or hard scale may need a larger cutter, multiple passes, or hydro jetting. If the line is under a driveway, the per-foot rate often rises because of the risk of hitting utilities.
What quotes leave out
Many quotes look low because they omit the camera inspection. A sewer camera adds $100 to $300, and it changes the recommendation from cleaning to repair. Another omission is the after-hours charge, which can be 1.5 to 2 times the day rate. Disposal of sludge and debris is a third hidden line.
A plumbing contractor business employee who lacks camera training often omits the sewer camera line from a quote. If the drain atmosphere may be hazardous, respiratory protection under OSHA's standard adds equipment and fit-testing expense. Lockout/tagout for drain machines and pumps is another cost, per OSHA's control of hazardous energy standard.
Where people overspend
Contractors overspend when they send a jetter to a simple sink clog. The hourly machine cost is far above a hand snake.
Customers overspend when they accept a flat rate without asking for a breakdown. Ask if the trip fee is waived with the repair. These questions often cut $50 to $100 from the final bill.
Example
A two-bathroom home in Dallas has a mainline clog. The plumber quotes a flat $275: a $75 trip fee, a $125 one-hour labor minimum, and a $75 machine charge.
The same 45-foot run priced per foot at $5 is $225, plus the $75 trip fee and a $75 machine charge, or $375. The flat rate wins here because the run is short and the clog clears in one pass.
If the drain still runs slow after snaking, a camera inspection costs $150 separately. The quote matches Texas's low-end hourly rates while keeping the flat price transparent.
