What we do
9 core services, each with a fixed quote before work starts. Prices below are honest 'from' guidance — your written quote is what you actually pay.
Burst pipes, major leaks, and sewage backups — a plumber answers around the clock and talks you through shutting off the water while we travel.
Acoustic sensors, thermal imaging, and pressure testing find hidden leaks in walls, floors, and slabs without tearing the room apart first.
Slow sinks, blocked toilets, and backed-up gullies cleared with augers or high-pressure jetting — then checked with a camera so it stays clear.
A camera survey shows exactly what is happening in the line — roots, cracks, bellies — followed by repair or trenchless relining where suitable.
Tank and tankless units serviced, repaired, or replaced and sized to the household — no more lukewarm showers or rumbling cylinders.
Galvanized, polybutylene, or tired copper replaced with modern PEX or copper — planned room by room to keep water on each evening.
Not sure what it is?
6 everyday plumbing symptoms and what usually sits behind them — plus the service that fixes each one.
Diagnosis starts here
You will see the likely causes and the right service for it. If water is going where it should not, shut off the internal stop tap and call us — day or night.
How a job runs
The same sequence on a dripping tap or a whole-house repipe — because the process is the product.
You describe the problem; we tell you immediately how to limit damage (like closing the main) and book the earliest slot.
On site we find the real cause, show you, and quote a fixed price for the agreed fix — before any work starts.
Floors covered, water off only as long as needed, quality parts fitted, and the work area kept tidy throughout.
We pressure-test, clean up, walk you through what was done, and leave the written workmanship guarantee.

Word of mouth
Short notes from recent jobs around the area — the kind of feedback a local firm earns one driveway at a time.
“They found the leak behind the bathroom wall in under an hour and had it fixed the same morning. The quote never moved.”
“Two other firms wanted to dig up the drive. Mainline relined the sewer from one small access point and showed me the camera footage.”
“Sunday night, water through the ceiling. They talked me to the stop tap on the phone and were at the door within the hour.”
