The pipe is cheap, the access is not
This shapes every decision in a service line replacement.
The pipe itself is a minor cost. What you are really paying for is opening the ground, working at depth, and putting everything back: driveway, path, lawn, planting.
Two consequences follow.
Trenchless is often cheaper overall, even though it costs more per foot, because it avoids most of the reinstatement. New pipe is pulled along the existing route from small pits at each end. Under hard landscaping the difference is large; across an open lawn it can go the other way.
Upsizing costs almost nothing now. If the existing line is undersized, which is common in older properties, correcting it during a replacement adds very little. Doing it later means paying for the same excavation twice.
Check the size before matching the old one
The default is to replace like for like, and it is worth pausing on.
A service line that has always struggled shows a specific symptom: pressure that drops noticeably whenever a second fixture runs. A shower that weakens when someone starts the washing machine, a tap that slows when the toilet refills.
If that has been normal in your house for years, the line may simply be too small for the way it is used, and no amount of work indoors will change it.
Replacement is the moment that becomes fixable, and it is the only moment where it is inexpensive.
Does this sound familiar?
Problems this service solves
- A buried line that has leaked more than once
- Old galvanised or polybutylene service line
- Pressure at the property limited by an undersized line
- A line damaged along its length rather than at one point
- A service line at the end of its material life
Signs you need water line replacement
If more than one of these is true, the problem is usually past the point a plunger or a store-bought cleaner will fix.
- The line has been repaired before
- Pressure is poor throughout the property
- The line is galvanised, polybutylene or of unknown age
- Wet ground appears in more than one place
What to expect
How the visit works
Establish the route and depth
Tracing the existing line and marking utilities comes before any decision about method.
Size it for the property
An undersized service line limits every fixture in the house, and replacement is the one chance to correct that.
Choose pulling or trenching
Where the route allows, new pipe can be pulled through from pits at each end, leaving the ground between undisturbed.
Connect, test and reinstate
The new line is connected at the meter and the house, pressure tested, and the ground restored.
What's included
What you get on every job, whoever we send.
- Sizing reviewed rather than matched to the old line
- Trenchless pulling assessed before an open trench
- Utilities located before any excavation
- Pressure tested before the ground goes back
Questions
Water Line Replacement questions
Can a water line be replaced without digging up the garden?
Often, yes. Trenchless methods pull new pipe along the existing route from small pits at each end, leaving everything between them undisturbed. It needs a workable route and reasonable ground conditions. Where the line runs under a driveway or mature planting, the saving is substantial because the reinstatement is what costs the money. On an open lawn with easy access, an open trench can genuinely be the better value.
Should the new line be a bigger size?
It is worth checking rather than assuming either way. Many older properties were served by lines that are undersized for how the house is now used, and that shows up as pressure dropping whenever two fixtures run at once. Because the cost of this job is in the excavation rather than the pipe, upsizing during a replacement is inexpensive. Doing it later means paying for the same access again.
How long does a service line replacement take?
For a typical residential run, usually a day or two, with trenchless work at the shorter end because there is far less ground to open and restore. The variables are the length of the run, the depth, what is above it, and how much utility locating and permitting the jurisdiction requires. The water is off for part of it, which is worth planning around.
