Moling in Crawley — Trenchless Pipe Replacement
Replace old lead, galvanised or leaking water mains in Crawley without digging up your garden, driveway or paving.
Trenchless water main and supply-pipe replacement across Crawley, Three Bridges, Pound Hill, Maidenbower and the surrounding West Sussex area.
Why moling makes sense for older properties
Many homes in Crawley 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 Crawley 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 Crawley actually involves
Housing stock and why supply pipes fail in Crawley
Crawley's New Town neighbourhoods — Langley Green, Southgate, Northgate, West Green, Three Bridges and Tilgate — were built out from the late 1940s through the 1960s. That era of housing very commonly has galvanised iron or early polythene supply pipes, and they are now all reaching the end of their service life at roughly the same time. Symptoms are consistent: brown or metallic-tasting water first thing, a slow drop in pressure over several years, then a leak that shows as a permanently green strip across the lawn.
Ground conditions across RH10 & RH11
Crawley sits on Weald Clay over much of its area, with alluvial deposits along the Gatwick Stream. Clay excavates slowly but bores cleanly. Where properties back onto the stream corridor the ground can be waterlogged, which we allow for with pump-out on the pits rather than treating it as an extra.
Access, driveways and reinstatement
New Town estates typically have short front gardens with the meter close to the boundary, so runs are short and jobs are usually finished well inside a day. Verge and footway crossings are more common in Crawley than in the surrounding villages, and we handle the notification side of that for you.
Water supplier and postcodes we cover
Crawley and the surrounding West Sussex villages are supplied by Southern Water and SES Water (varies by neighbourhood), and the properties we work on are mainly in the RH10 & RH11 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 Crawley include Ifield, Langley Green, Southgate, Tilgate, Pound Hill, Maidenbower, Broadfield, Bewbush and Gossops Green. 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.
