We aim to be with you the same day for emergency jobs across Warrington and Manchester. In most cases our engineers are on site within a few hours of your call.

Private drains within your property boundary are your responsibility. Public sewers — shared with neighbours or running under public land — are managed by United Utilities. If you're not sure, call us and we'll advise for free before any work starts.

Water draining slowly or not at all, unpleasant odours, gurgling sounds from sinks or toilets, and water backing up in showers or basins. Don't ignore early signs — small blockages become expensive ones.

The most common causes are grease and fat, food waste, hair, wet wipes, and foreign objects. Tree roots growing into older pipes are also a major cause in North West properties. Regular inspections can catch these early.

Yes. Left untreated, blocked drains lead to water damage, damp, structural issues, and health hazards from bacteria and raw sewage. It's always cheaper to deal with a blockage early.

Most standard blockages start from £59. We agree a price before any work begins — no hidden extras, no call-out charge. Complex jobs or CCTV surveys are priced separately and always quoted upfront.

We insert a small, flexible camera into your drain pipe and send the footage to a monitor in real time. It lets us pinpoint exactly where a blockage or damage is — without digging anything up. It's quick, clean, and non-destructive.

If you have recurring blockages, slow drains that don't respond to jetting, unexplained damp, or you're buying a property and want to check the drain condition before you commit. CCTV surveys start from £59.

Yes. We provide a full written report with footage so you can see exactly what we found and understand the recommended next steps. No jargon, no pressure.

Drain lining is a no-dig repair method. We insert a flexible liner into the damaged pipe, inflate it, and cure it in place with UV light — creating a new pipe within the old one. No excavation required.

A drain pipe that has caved in due to ground movement, tree roots, age, or sustained blockages. A collapsed drain needs professional repair quickly — left untreated it causes water damage, subsidence, odours, and pest problems.

A correctly installed drain lining is expected to last up to 50 years. It's a permanent repair, not a temporary fix.

In most cases, no. Our no-dig drain lining and jetting methods mean we can fix the problem without excavation. We'll always tell you upfront if a dig is unavoidable.

Drain lining in Warrington typically costs between £500 and £3,000 depending on the length and diameter of the pipe, the extent of the damage, and how accessible the drain is. Smaller domestic repairs sit toward the lower end; longer runs or collapsed sections in harder-to-reach areas cost more.CDNW always carries out a CCTV survey before quoting, so you get a clear price based on the actual condition of your drain — not an estimate.
