Hot and cold, day and night

Plumbing and heating is two halves of one job: the cold water coming in and the hot water going round. That’s the red and the blue on every tap, and on our logo.

Glasgow has plenty of both kinds of trouble. Tenement flats with shared pipes and old lead, a leak from upstairs at teatime, a boiler losing pressure because of a forgotten radiator pipe. Our reviews are full of those calls, and full of Derek’s name.

We’ve fitted bathroom suites for over 17 years, and done general plumbing for over 26 years. No job is too big or too small.

The van comes stocked

We carry the common parts and the right tools, so a lot of jobs are finished on the first visit instead of a second trip after the merchants. Give the tools a nudge.
