Clogged Drain Repair Cost Calculator
The Clogged Drain Repair Cost Calculator estimates what it costs to fix a blocked drain properly. Choose where the clog is, then tick what the drain needs, from clearing the clog to replacing a trap, a toilet flange or a section of damaged pipe. You get a planning budget split into materials, labor, service call and equipment, and any permit or patching allowance, with budget, standard and premium ranges. It is free and takes under a minute. It is a planning estimate, not a bid.
Estimate your clogged drain repair cost
Choose the clogged drain and the repairs that apply to it appear. "Clear the clog" is ticked for you; add any repair the drain also needs, or untick clearing if the drain is already open. If you choose to replace a section of pipe, one more question asks where the pipe is. Only your ZIP code, the drain and at least one repair are required.

How much does it cost to fix a clogged drain?
Clearing a clogged sink, tub or toilet drain typically budgets at about $230 to $320. When the drain also needs a repair, the cost depends on what has failed and where it is. Replacing a sink trap brings the job to about $400 to $480 with the clearing, while replacing a section of pipe inside a wall budgets at about $1,000 to $1,200. These planning figures assume normal working hours, and each includes a service call.

Planning estimates from the OmniEstimate calculator. Pipe repairs inside a wall and sewer line repairs include a permit allowance. They are not quotes.
Quick answer: What is the average cost to fix a clogged drain? Clearing a clogged sink, tub or toilet drain typically budgets at about $230 to $320, including a service call, based on OmniEstimate’s standard planning assumptions. If a trap, fitting or section of pipe also needs replacing, the cost rises to between about $400 and $1,200 depending on the repair and where the pipe is.
How this calculator works
The calculator prices each repair for the drain you choose, keeping materials and labor apart. If you select several repairs, the most labor-heavy one is charged in full and each additional repair at about 80 percent of its labor, because the plumber is already on site. A pipe repair is priced by where the pipe is. One service call is added for the visit, and a permit allowance is added only for work that commonly needs a permit.
The three repair levels are built from different inputs for parts, plumber experience and warranty. They are not one number multiplied up and down. Your ZIP code identifies your market for contractor matching and does not change the price.
| Repair | Kitchen or bathroom sink | Tub or shower | Toilet |
|---|---|---|---|
| Clear the clog | $230 – $310 | $250 – $300 | $240 – $290 |
| Replace the trap | $270 – $320 | $360 – $430 | Not applicable |
| Replace drain fittings | $250 – $300 | $370 – $440 | Not applicable |
| Pull and reset the toilet | Not applicable | Not applicable | $290 – $350 |
| Replace the toilet flange | Not applicable | Not applicable | $360 – $430 |
| Clear a blocked vent | $270 – $320 | $270 – $320 | $270 – $320 |
| Replace a pipe section, in the open | $490 – $575 | $490 – $575 | $490 – $575 |
Standard-level planning estimates. A bathroom sink is at the lower end of the clearing range and a kitchen sink at the upper end. A floor or laundry drain budgets at $270 to $320 to clear and $420 to $500 for a new trap.
For the main sewer line, snaking budgets at about $430 to $525, hydro-jetting with a camera at about $975 to $1,150, a new cleanout at about $925 to $1,100 and a spot repair of up to 10 feet of buried line at about $2,300 to $2,750.
Quick answer: What is a P-trap? A P-trap is the curved section of pipe under a sink, tub or shower. It holds a small amount of water that blocks sewer gas from coming up the drain. It also catches debris, which makes it a common place for clogs. Replacing a sink P-trap budgets at about $270 to $320.
Quick answer: What is a toilet flange? A toilet flange, also called a closet flange, is the fitting that fixes the toilet to the floor and connects it to the drain pipe. A broken or corroded flange lets the toilet rock and leak at the base. Replacing one budgets at about $360 to $430 in OmniEstimate’s standard estimate.
Quick answer: Why is a drain pipe repair inside a wall so expensive? A drain pipe repair inside a wall costs more because the wall has to be opened to reach the pipe, the work is slower in a confined space, and a permit is often needed. OmniEstimate budgets about $1,000 to $1,200, against about $490 to $575 for the same repair on exposed pipe.
What affects the cost of a clogged drain repair?
Whether cleaning is enough
Most clogs only need clearing. A repair is needed when something is damaged or keeps catching debris: a cracked or packed trap, worn drain fittings, a broken toilet flange, a blocked vent, or a pipe that has cracked, corroded or sagged.
Where the damaged pipe is
Access is usually the biggest part of a drain pipe repair. The same section of pipe budgets at about $490 to $575 in the open, $1,000 to $1,200 inside a wall or floor, and $2,300 to $2,750 under a concrete slab. Pipe under a slab needs the concrete cut and removed, which adds labor and equipment.
Patching afterward
Plumbers usually open a wall, floor or slab to reach a pipe but do not put the finish back. The optional patching allowance adds about $230 to $280 for a wall or floor and about $450 to $550 for a slab. Painting and new flooring are not included.
How many repairs are done together
Combining repairs in one visit shares the service call. Clearing a bathroom sink and replacing both its trap and its drain fittings budgets at about $525 to $625 together. On a toilet, pulling it and replacing the flange at the same time budgets at about $525 to $625.
Emergency timing
Emergency and after-hours work raises labor by about 50 percent and doubles the service call. Clearing a kitchen sink moves from about $260 to $310 to about $430 to $500, and clearing it with a new trap from about $400 to $480 to about $625 to $750.
Material and labor costs
Parts for most drain repairs are cheap, and labor and access make up the bill. For a sink trap replacement, the calculator budgets about $35 to $45 for parts and $140 to $170 for labor at standard pricing. For a pipe section inside a wall, it budgets about $90 to $110 for materials and $675 to $850 for labor.
Permits, cameras and other costs
Service call. About $90 to $110 at standard pricing, charged once per visit.
Permit allowance. About $140 to $170, applied to pipe repairs inside a wall or under a slab and to sewer line repairs. Without it, a pipe repair inside a wall budgets at about $875 to $1,050.
Camera inspection. Adds about $250 to $310. It is worth doing before any pipe repair, so you know where the damage is and how much pipe needs replacing.
Equipment. Sewer line repairs and new cleanouts include excavation, and slab repairs include concrete cutting.
Signs a clog needs a repair, not just cleaning
| Sign | Likely cause | Repair to select |
|---|---|---|
| The same drain blocks again within weeks | Trap packed with build-up, or a problem further down | Replace the trap; add a camera inspection |
| Water leaks under the sink when it drains | Cracked or corroded trap or fittings | Replace the trap or drain fittings |
| Drains gurgle and empty slowly | Blocked roof vent | Clear a blocked vent |
| Toilet rocks or leaks at the base | Broken flange or failed wax ring | Replace the toilet flange |
| Something was dropped or flushed | Object lodged in the toilet trap | Pull and reset the toilet |
| Several fixtures back up together | Blockage or damage in the main sewer line | Main sewer line repairs |
What this estimate does not include
- Painting, tiling or new flooring after a wall, floor or slab is patched.
- Restoring a driveway, walkway or landscaping after a buried line is dug up.
- Replacing more than a short section of sewer line.
- Cleaning up or repairing water or sewage damage inside the home.
Regional pricing differences
Labor rates, service call fees and permit fees differ from one market to another. The calculator does not adjust for location. Treat the result as a national planning range, then get quotes from local plumbers to see where your market sits.
How to avoid unexpected costs
- Ask for a camera inspection before agreeing to any pipe repair, and ask to see the footage.
- Ask whether opening and patching the wall, floor or slab is included, and who does the finishing.
- For pipe under a slab, ask whether the line can be rerouted or relined instead.
- Ask whether the repair needs a permit and whether the fee is in the quote.
- Ask what guarantee you get if the drain blocks again.
Questions to ask a plumber
- What caused the clog, and how do you know?
- Will clearing it be enough, or does something need replacing?
- Where exactly is the damaged pipe, and how will you reach it?
- Is this a fixed price, and what could change it?
- What warranty do you give on the repair?
When to hire a professional
A plunger, a hand auger or cleaning out a sink trap clears many simple clogs. Call a plumber when a clog will not shift or keeps coming back, when several fixtures are affected, when sewage is backing up, or when the fix involves pipe inside a wall, under a slab or underground. Those repairs need the right tools, and often a permit.
Frequently asked questions
How much does it cost to fix a clogged drain?
Clearing a clogged sink, tub or toilet drain typically budgets at about $230 to $320 at standard pricing, based on this calculator’s assumptions. If the drain also needs a repair, the cost rises: clearing a kitchen sink and replacing its trap budgets at about $400 to $480, and replacing a section of drain pipe inside a wall at about $1,000 to $1,200.
How much does it cost to replace a P-trap?
Replacing the P-trap under a kitchen or bathroom sink budgets at about $270 to $320 at standard pricing, including a service call. The part itself is inexpensive. A trap under a tub or shower is harder to reach and budgets at about $360 to $430, and a floor drain trap at about $420 to $500.
How much does it cost to get something out of a toilet?
If an object cannot be reached with an auger, the plumber removes the toilet, retrieves the object and resets the toilet on a new wax ring. That budgets at about $290 to $350 at standard pricing. If the plumber tries an auger first and then has to pull the toilet, the total is about $410 to $500.
How much does it cost to replace a drain pipe?
It depends on where the pipe is. Replacing a section of drain pipe that is in the open, such as under a sink or in a basement, budgets at about $490 to $575 at standard pricing. Inside a wall or floor it budgets at about $1,000 to $1,200, and under a concrete slab at about $2,300 to $2,750, before any patching.
Why does my drain keep clogging after it is cleared?
A drain that blocks again soon after cleaning usually has a cause that cleaning does not remove. Common causes are a trap packed with build-up or damaged, a blocked roof vent, a pipe that sags or has the wrong slope, and roots or a break in the sewer line. A camera inspection is the usual way to find out which.
How much does it cost to install a sewer cleanout?
Installing a cleanout on the main sewer line budgets at about $925 to $1,100 at standard pricing. A cleanout gives direct access to the line, so every future cleaning is quicker and cheaper. Having the line snaked at the same visit brings the total to about $1,200 to $1,450.
Can I fix a clogged drain myself?
Often, yes, for a simple clog. A plunger, a small hand auger, or removing and cleaning the P-trap under a sink clears many blockages. Call a plumber when the clog will not shift, keeps coming back, affects several fixtures, or when sewage is backing up into the home.
Does my ZIP code change the estimate?
No. The calculator uses your ZIP code to identify your market and match you with local professionals. It does not adjust the price. Local labor rates and permit fees do vary, so use the result as a planning range and compare it with quotes from plumbers in your area.
