How Much Does Drain Jetting Cost? What Sets the Price

How much drain jetting costs depends on four things more than on the machine itself: the time band you book in, what is actually in the pipe, how long the run is, and whether the job needs a van-mounted jetter or a larger tanker unit. Our own figures for each time band sit on the published rate card; this guide explains what moves a jetting quote up or down, so you can tell a fair price from a padded one before anyone connects a hose. If you are pricing a routine clean rather than clearing a blockage, see how much drain cleaning costs for what a planned clean includes.

What are you actually paying for when a drain is jetted?

You are paying for an engineer's time on site, the jetting unit and its water, and the checking that proves the pipe is clear. A fair quote names each of those, rather than giving one number with nothing underneath it.

Jetting pushes water at high pressure through a hose and a nozzle fed into the drain from an access point, usually an inspection chamber or a rodding eye. The nozzle drives itself forward and scours the pipe wall on the way back. For a domestic blockage the equipment is normally a van-pack jetter. For long commercial runs, heavy silt or fat build-up in a restaurant drain, the job may need a combination unit that jets and sucks the waste away at the same time. Those two machines cost very different amounts to run, which is the first reason two jetting quotes for the "same" job can be far apart.

Time band is the second. A job booked in standard daytime hours is priced lower than the same job at night, and a reputable firm tells you which band you are in before the engineer sets off, not on the invoice.

Why does the type of blockage change the price?

Because some blockages clear in one pass and others need repeated passes, different nozzles or a second tool. The cause decides the time on site, and time is most of the bill.

Roughly, from quickest to slowest:

• Soft blockages such as wipes, paper or silt near a chamber. Often cleared quickly, and sometimes rodding alone would have done it.
• Fat, oil and grease. Hardened fat coats the pipe wall and needs several passes with a scouring nozzle. Commercial kitchen drains fall here, and it is why our note on fatbergs and what they cost to remove spends time on prevention.
• Scale. Mineral build-up in older pipes is slow to shift with water alone and may need a descaling head.
• Tree roots. Water pressure can push through a root mass but rarely removes it. Roots normally need a mechanical cutter, which is a separate line on a quote. Our root cutting service covers that job.

If a quote does not say what the engineer thinks the cause is, ask. The answer tells you whether the price is based on a diagnosis or a guess.

How do run length and access affect a jetting quote?

A longer run takes more hose, more passes and more time, and a run with no usable access point may need one found or opened before jetting can start. Both push the price up, and both should be visible on the quote.

In London terraces the main run often passes under several gardens or under the house itself before reaching the sewer, and the only access may be a chamber at the back or a rodding eye at the front. Where access is buried under paving, has been built over, or is missing entirely, the engineer either works from a less convenient point or has to open one up. That is legitimate extra work, but it should be quoted as its own line rather than folded into a vague total. Commercial sites add another variable: working around trading hours or a shared yard can mean an evening or early booking, which puts the job in a different time band.

Should a CCTV check be included in the price?

Yes, where the cause is not obvious or the blockage has come back. A camera run after jetting is the only way to show that the pipe is clear along its length, and whether the blockage was a symptom of damage.

A drain that blocks repeatedly is usually telling you something structural: a displaced joint catching debris, a dip holding standing water, or a crack letting roots in. Jetting clears the symptom, and without a camera nobody knows whether it will be back next month. Some firms sell a camera check as a separate visit afterwards. We would rather put it on the same quote where it is warranted, so you pay for one attendance rather than two. If you need a full coded record for an insurer or a sale, that is a CCTV drain survey rather than a quick check, and it should be priced as such.

When is jetting the wrong answer?

Jetting is the wrong answer when the pipe is broken, collapsed or made of a material that high pressure can damage. In those cases paying for jetting only adds a line to a bill that still ends with a repair.

Three situations to watch for:

• A collapsed or badly displaced section. Water will not clear a pipe that is no longer round, and forcing a nozzle through can make it worse. A camera should come first.
• Pitch fibre pipe. Common in homes built from the 1950s to the 1970s, pitch fibre can blister and deform with age, and high pressure risks damaging it further. Lower pressure or mechanical methods are usually safer.
• A simple blockage close to an access point. Sometimes rods clear it in minutes. A firm that insists on jetting for every job is selling the machine, not the fix.

How do you compare two jetting quotes fairly?

Compare what each quote includes, not the headline figure. Put the same questions to both firms and the difference usually explains itself.

Ask each firm: which time band is this priced in; is the price for the attendance or for a cleared drain; which machine are you sending; does the price include a camera check, and is footage or a written note handed over; and what happens, and at what rate, if the job runs longer than expected. A cheaper quote that excludes the camera, charges waste disposal separately and bills extra time in large blocks can end up costing more than a higher, complete one. Our piece on what cheap drain unblocking really costs goes through the common add-ons in more detail.

Finally, check who owns the pipe before you book anyone. If the blockage is on a shared run or beyond your boundary, it may belong to the sewerage undertaker, in which case jetting it is their job and not yours to pay for.
