How Long Does Drain Unblocking Take? Honest Timings from People Who Do It All Day

Fair question, honestly answered, because when your only bathroom is out of action, “how long” is not idle curiosity. It is the whole conversation.

There are two clocks running: how long until someone arrives, and how long the fix takes once they do. People quote the first and mean the second, so here are both, straight.

Clock one: arrival

Across the TW area we are typically on site within 60 to 90 minutes of the call, around the clock. You get an ETA for your actual street when you ring, from a person who knows where the van is, and if a Richmond rush hour or a Twickenham match day is going to add to that, we say so on the phone rather than letting you find out by waiting.

Clock two: the fix itself

Honest on-site timings, from the work we do every day:

• Blocked toilet or sink: usually under an hour. Most clear in twenty to forty minutes with the proper tools. The supermarket plunger you already fought it with was not a proper tool, and no, we will not ask what went down. It will not be the strangest thing this week.
• A blocked drain run: one to two hours. Finding the blockage from the chambers, clearing it at source with rods or the jet, then the part a cheap job skips: running water through and watching it prove itself. We do not leave on a maybe.
• Jetting a whole run: one to two hours, longer for heavy commercial grease. Jetting is thorough by nature; it strips the pipe wall rather than poking a hole for the water to sneak through, which is exactly why it beats rodding for repeat blockages.
• CCTV survey: one to two hours, as a planned visit rather than an emergency dash.
• Patch repair or relining: usually one day for a domestic run, as its own booked job. Resin cures on chemistry’s schedule, not ours.

What makes a job run long

The overruns are nearly always one of three things, and none of them is a mystery once you have seen enough drains:

1. Hide-and-seek with the access. The inspection chamber is under decking, a rockery, or a beautifully laid patio. (Teddington, we still love you.) Finding it is part of the job, but it is minutes that add up.
2. Compacted grease. Fat that has had years to harden takes repeated jetting passes. It always loses; it just negotiates first.
3. The blockage is a symptom. If the camera shows a collapsed joint, root ingress or a deformed pipe, clearing gets tonight’s water moving and the real fix becomes a planned repair. That is not the job running long; that is a different, honest conversation, with footage.

One thing that never changes with the clock: the price. It is agreed before work starts, and a stubborn blockage is our problem to sweat, not a meter running against you. The fastest thing you can do for either clock is call the moment a drain turns slow, because a slow drain is a cheap problem and a stopped one is not.
