Frequently Asked Questions
Everything you need to know before booking a free site visit.
Common signs include a sudden rise in your water bill, low pressure at the tap, damp patches in the lawn or driveway, the sound of running water when nothing is on, and your water meter ticking over when all taps are off. If you spot any of these, get a specialist out quickly — small leaks waste a lot of water and can undermine driveways and foundations.
The supply pipe from the boundary stop tap into your home is almost always the homeowner's responsibility. The water company looks after the main in the road and the communication pipe up to the boundary. If you're unsure, we'll check during our free site visit.
Yes — wherever possible we use a trenchless technique called moling. A pneumatic mole bores a clean tunnel underground and pulls a new MDPE pipe through, needing only a small entry and exit pit. Most gardens, lawns, driveways and patios stay completely intact.
Every job is different — it depends on the length of pipe, the ground conditions and access. We give every customer a free site visit and a fixed written quote before any work starts, so you know exactly where you stand.
Yes. We replace old lead and galvanised supply pipes with modern blue MDPE plastic, which is safer, more durable and approved for drinking water. Water companies often part-fund lead replacements — we'll point you in the right direction.
We aim to attend free site surveys within a few working days, and urgent leaks usually the same week. Call us on 07894 956041 to discuss your situation.
We cover East Grinstead, Crawley, Horsham, Haywards Heath, Forest Row, Uckfield, Reigate, Redhill, Burgess Hill and the surrounding Sussex & Surrey area. If you're nearby, give us a call.
