What we do

Plumbing & heating, under one roof

One licensed crew for the water, the heat and the gas — no juggling three companies.

No job too big — and no job too small.

The Calgary water problem

Calgary’s water is quietly eating your water heater.

At 13–16 grains per gallon, Calgary runs some of the hardest water in Canada. Left untreated, scale coats the inside of your tank and pipes — costing you efficiency, hot water and years of tank life.

13–16grains / gallon — “very hard”
~30%shorter water-heater life
15–30%efficiency lost to scale

We install and service the water softeners that stop it — and we’ll tell you straight whether you actually need one.

Our whole reputation

No surprises at the end.

You get a clear price before we start. That’s the number you pay — no hidden costs, no “while we were in there,” no pressure to buy what you don’t need.

01

We quote it straight

We look at the real job and give you an honest, itemised price — before a single tool comes out.

02

We do it right

Done properly the first time, tidy when we leave, and often a little ahead of schedule.

03

You pay what we said

The agreed price is the final price. That’s the whole reason our customers come back.

★★★★★
