How quickly can you come out?

For non-emergency blockages, we aim to get an engineer to you the same day or next day. If it's urgent — water backing up, sewage smells, or flooding risk — call our emergency line and we'll prioritise getting to you as fast as possible.

How much does it cost to unblock a drain?

It depends on the cause and how accessible the blockage is, but we'll always give you a clear price before starting any work. Simple blockages are usually straightforward; anything requiring CCTV investigation or jetting will be quoted once we know what we're dealing with.

Can I unblock a drain myself first?

For a single slow-draining sink, a plunger or a kettle of hot water is worth trying. If more than one drain is affected, or the problem keeps coming back, it's best to get a professional out before it turns into a bigger (and messier) job.

Why does my drain keep blocking?

Recurring blockages usually mean the root cause hasn't been dealt with — often tree roots, a damaged pipe, or a buildup further down the line than a quick clear can reach. A CCTV survey will show us exactly what's going on so we can fix it properly.

Signs you need this service

Water draining slowly in sinks, showers, or baths — often the first warning sign before a full blockage
Gurgling sounds from pipes or plugholes, especially after flushing or running a tap elsewhere in the house
Unpleasant smells coming from drains, even when surfaces are clean
Water backing up into a sink, toilet, or shower — particularly if more than one fixture is affected at once

What we do

Most blocked drains in Northamptonshire homes and businesses come down to a handful of causes: grease and food waste in kitchen pipes, hair and soap residue in bathroom drains, or tree roots and leaf debris working into external drains over time. Our engineers don't just clear the immediate blockage — we find out why it happened, so you're not calling us back out in three months for the same problem.

Every job starts with a proper assessment. For straightforward blockages, that often means high-pressure water jetting or rodding to clear the line completely. For anything less obvious — a recurring blockage, or one where the cause isn't visible from the surface — we'll use a CCTV drain camera to see exactly what's going on inside the pipe before we touch anything. That means no guesswork, no unnecessary digging, and no paying for work you didn't need.

Once it's cleared, we'll talk you through what caused it and what (if anything) you can do to stop it happening again — whether that's a simple habit change or, in some cases, a longer-term fix like relining a damaged section of pipe.

Is it actually your problem? We check before you pay.

If a problem turns out to be your local water authority's responsibility rather than a private repair, we tell you before any work goes ahead — and provide a written report you can use to pursue a claim.
