Drain Cleaning Flat Rate vs. Hourly: Which Makes More Money?

You get a drain cleaning call. You arrive, snake the main line, and the clog clears in 15 minutes. Do you charge the customer $75 for a quarter hour of your time, or $275 for solving the problem? One of these builds a business. The other builds a side-hustle that will never make real money.

The Hourly Trap

Hourly pricing on drain cleaning has three built-in problems:

• Customer anxiety about the clock — "how long is this going to take?" is the first question, and every minute feels adversarial
• Punishes efficiency — a tech who clears the clog in 15 minutes bills less than one who takes 90 minutes. The faster tech makes less money.
• Invites disputes — when the invoice shows "0.25 hours labor" the customer argues about the service charge or trip fee

Flat rate removes all three. The price is the price. The customer paid for a working drain. Everyone goes home.

Flat Rate Pricing That Works

Standard menu for 2026:

• Branch drain (sink, tub, shower) — $150–$225
• Toilet pulled and reset for stoppage — $225–$325
• Main line via accessible cleanout, snake — $225–$375
• Main line hydro-jet — $400–$700
• Sewer camera inspection — $200–$400 (often credited back if work follows)
• Emergency / after-hours surcharge — $75–$150
• Cleanout installation (new access point) — $400–$900 (separate quote)

The Hidden Economics

Compare the daily revenue potential:

Hourly ($85/hr): 5 drain calls per day, 1 hour on-site + 0.5 hour drive each = 7.5 billable hours. Daily revenue: $637.50.

Flat rate ($275 main line average): 5 drain calls per day. Daily revenue: $1,375.

Same calls, same vehicle, same miles — more than double the revenue. The customer gets a known price. The tech gets rewarded for efficiency. The business captures the real value of the work.

Scoping the Flat Rate

Every flat rate needs a defined scope so you are not giving away unlimited work:

• Main line snaking — includes clearing from accessible cleanout, up to 100 feet of cable, standard blade heads. Excludes: cleanout installation if none exists, hydro-jetting if the snake does not clear, pipe repair.
• Camera inspection — includes 100 feet of camera travel from accessible access point, DVD or digital video delivered to customer. Excludes: locate transmitter work above 10 feet depth, pipe locating in walls.
• If scope expands — quote the additional work separately. The customer approves before you proceed. No surprise invoices.

What to Camera Before Snaking

Snaking a damaged pipe (offset joint, root intrusion, broken clay, bellied section) temporarily clears the clog but the problem returns in 30–90 days. The customer blames you. Camera-inspect any main line call that has recurred within 6 months. If you find pipe damage, your quote shifts from $275 drain cleaning to a $3,500–$15,000 trenchless repair or dig-and-replace. That is the real money in the drain business. Snaking is the entry point.

Guarantees

Offer a 30-day no-clog guarantee on standard snaking of pipes you have camera-inspected as structurally sound. Do not guarantee pipes with root intrusion, offsets, or belly sections — note the condition on the invoice. If the drain recurs within the guarantee period on a sound pipe, return no-charge. The reputation is worth more than the one callback.
