    Moling in Three Bridges — Trenchless Pipe Replacement

    Replace old lead, galvanised or leaking water mains in Three Bridges without digging up your garden, driveway or paving.

    Trenchless pipe replacement across Three Bridges, Pound Hill, Worth and the wider Crawley area.

    Why moling makes sense for older properties

    Many homes in Three Bridges still run on the original water supply pipe — often lead, galvanised iron or early polythene. Once these pipes start leaking or restricting flow, the textbook fix is to replace the run between your stopcock and the house. The expensive part isn't the pipe; it's the digging.

    Moling solves that. A pneumatic mole is fired horizontally underground between two small pits — one at the meter, one at the property. It pulls a new 25 mm or 32 mm MDPE pipe behind it. Your driveway, lawn and patio stay in place, and the job is normally finished in a day.

    We cover Three Bridges and the surrounding area regularly, so we already know the typical ground conditions and supply layouts you're likely to have.

    What moling work in Three Bridges actually involves

    Housing stock and why supply pipes fail in Three Bridges

    Three Bridges combines Victorian railway housing near the station with 1950s and 60s Crawley New Town estates and later development at Pound Hill and Maidenbower. The railway-era terraces are where lead is still found; the New Town properties typically have galvanised iron or early polythene that is now at the end of its life.

    Ground conditions across RH10

    Weald Clay dominates, with made ground close to the railway corridor. Made ground can contain buried rubble and old services, so we CAT-scan and hand-dig the first section of every pit near the line rather than assuming a clear route.

    Access, driveways and reinstatement

    Front gardens here are typically short, so runs are usually 8 to 15 metres and jobs are quick. Where the property fronts directly onto the pavement we keep the footway opening as small as possible and reinstate the same day.

    Water supplier and postcodes we cover

    Three Bridges and the surrounding West Sussex villages are supplied by Southern Water, and the properties we work on are mainly in the RH10 postcode area. Your water supplier is responsible for the main in the road and the communication pipe up to the boundary stop tap; the supply pipe from the boundary into your home is the homeowner's responsibility, and that is the section we replace, repair and leak-locate.

    Streets and neighbourhoods we regularly work in around Three Bridges include Pound Hill, Maidenbower, Worth, Northgate, Tinsley Green, Hazelwick and Church Road. If you are just outside these, it is still worth calling — most of West Sussex is within our normal working radius and there is no charge for a quote.

    FAQs — Moling in Three Bridges

    Most domestic moling jobs in Three Bridges come in between £1,200 and £2,800 — roughly £80–£150 per metre for a new 25 mm or 32 mm MDPE supply pipe. The final figure depends on the length of the run, the ground conditions underneath your drive or garden, the depth of the existing pipe and how easy the meter and stop tap are to reach. We never quote blind: you get a free site visit and a fixed written quote before any work starts, with no call-out fee.

    Yes — we cover the whole of Three Bridges (RH10) and the surrounding villages, including Crawley and Horley. We're based in Crawley Down, West Sussex, and work right across West Sussex, Sussex and Surrey, so Three Bridges is a routine local call-out for us rather than a long-distance job.

    No — that is the entire point of moling. Instead of cutting a trench from the boundary to the house, we dig two small access pits (typically around 600 mm square): one near the water meter or stop tap, and one where the pipe enters the property. A pneumatic mole is then fired underground between them, pulling the new MDPE pipe behind it. Block paving, tarmac, concrete, lawn, patios, flowerbeds and mature planting all stay exactly where they are. The only reinstatement needed is the two small pits, which we backfill and make good before we leave.

    A typical 15–25 m domestic water main replacement is completed in a single working day. That includes digging the two access pits, moling the new pipe through, connecting at the boundary stop tap and inside the property, fitting a new internal stop tap where needed, pressure testing, flushing the new main and backfilling. You are usually left with water back on the same evening — we would only ever need a second day on unusually long runs, shared supplies or very difficult ground.
