How mains renewal is priced in Aldershot
Renewal is priced like installation — per-metre laying plus connection and statutory costs — with the addition of decommissioning the old main. Renewal is the answer when an aged main bursts repeatedly or can no longer carry the demand; renewal becomes more economical once repairs are needed regularly.
How a main is renewed without opening the street
Modern renewals are mostly trenchless: a new PE main is inserted through the old one (slip-lining), or the old pipe is burst and a same-size or larger main pulled through in its place — open excavation is saved for the connection points at each end. Whole runs renew from a handful of pits, which is why supply interruptions stay short and planned.
Why old mains fail
Cast and ductile iron mains fail slowly: corrosion thins the wall, joints lose their packing, ground movement cracks brittle sections — and inside, rust nodules build into tuberculation that chokes the bore. That last one is why an ageing main typically produces falling pressure and discoloured water long before it bursts.
Repair or renew?
One burst: repair. A pattern of bursts on the same aged run, pressure complaints, or discoloured water: renewal quotes belong on the table. The survey and burst history make the case one way or the other.

Water Main Renewals in Aldershot — common questions
Can we keep water on during the works?
Usually yes — the new main is laid and tested alongside the old one, with a short planned changeover at the end.
How disruptive is a renewal?
Modern insertion and moling techniques renew long runs with pits rather than open trench — supply interruptions are planned and short.
Can the old main stay in the ground?
Usually, once properly decommissioned and capped — removing it is rarely worth the excavation.
Who pays for renewing a private main?
Whoever owns it — and on estates, parks and shared private mains that usually means the owners collectively, apportioned through the management company or the deeds. Establish the split before commissioning; the quotes are the easy part.
