What is different about a commercial leak
The water does not stop when everyone goes home
A leak on a business premises runs through the nights and the weekends with nobody there to notice a damp patch or hear a hiss. The first sign is almost always the bill, and by then it has had a full quarter to run.
You cannot always shut the water off to find it
In a house, isolating the property for twenty minutes is an inconvenience. In premises that need water to trade, it is lost hours. The detection has to be planned around when you are not operating.
The meter is usually further away, and the run is longer
More buried pipe between the meter and the building means more places for a service line to fail, and more ground to narrow down.
There is more of everything
More fixtures, more outlets, more separate wet areas, and often more than one tenancy on a single meter.
The consumption baseline is higher
A leak hides inside a commercial water bill far longer than it hides in a domestic one, because the normal number is already large and variable.
Where the commercial work is around Harrisdale
Harrisdale is overwhelmingly residential — 98.5% of occupied dwellings are separate houses — so the commercial work here is the business that serves the suburb rather than a light-industrial estate.

Stockland Harrisdale on the corner of Nicholson Road and Yellowwood Avenue opened in 2016 and anchors the retail side. Carey Baptist College and Harrisdale Senior High School bring the sort of premises that cannot simply turn the water off mid-morning. Warton Road, Ranford Road and Nicholson Road carry the commercial frontage around the edges of the suburb.
Across our wider patch there is more of it — the commercial and light-industrial run along Ranford Road and Bannister Road in Canning Vale in particular, and the older commercial strips through Thornlie, Gosnells and Armadale. We do the same work there. Suburbs we cover
What we do for commercial premises
Leak detection
The same elimination method, worked around your trading hours. Meter, isolation, acoustic location, pressure test, then one opening in the right place rather than several in hopeful ones. How leak detection works
Burst pipes and urgent repairs
Water isolated, damage stopped, repair priced in writing, section retested before we leave. Emergency plumbing
Blocked drains
Cleared, and then the question of why — because a commercial line that blocks on a Friday and blocks again a month later is a trading risk, not a maintenance item. Blocked drains
Storm water and soakwells
Run-off from larger roofs and larger hard surfaces, and the pooling water that gets reported as a leak. Storm water and soakwells
Gas
Gas leak detection and repair under gas licence 13098, with the compliance paperwork the work requires. Gas leak repair
How we work with a business
No call-out fee
The visit to find out what you are dealing with costs nothing, which matters when you are not yet sure whether you have a leak or a billing error.
A written price before work starts
Transparent pricing, no hidden costs. You get something you can put in front of whoever approves spending, rather than a verbal estimate and a surprise.
Scheduled around trading where it can be
Detection work needs the water quiet, and quiet usually means before you open. We work Monday to Friday, 7:00am to 4:00pm, and the early end of that is often the useful end for commercial jobs.
One licence holder, start to finish
Tim quotes it and Tim does it. Plumbing licence 8396, gas licence 13098. For premises where access, keys and security matter, that is fewer people to arrange for.
Landlords, tenants and who pays
We do not give legal advice, and we will not tell you what your lease says. What we can give you is the thing that usually settles it: a clear written account of what failed, where it is, and whether it sits in the building, in the service line, or in the ground outside.
Water Corporation's position on the water itself is simple enough — the main in the street is theirs, and everything past the meter belongs to the property. Where it sits between owner and tenant after that is your lease's business, not ours.
Get it looked at
Tell us what you have noticed — the bill, the damp, the sound — and we will call you back to arrange a time that does not cost you trading hours.
