Chromed pipework

Plumbers in Cornwall and Devon.

Plumbing.

Domestic plumbing and commercial water services from one office. Pipework, underfloor heating, drainage and leak detection, all pressure tested before sign-off.

A house needs pipework, maybe a bathroom, maybe underfloor heating, and a leak found before the floor comes up. A commercial building needs hot and cold water services, unvented storage, tank cleaning and disinfection, and records to prove it was done. Same underlying skill, different paperwork, and we handle both.

Common questions

Before you call

Who do I call for an emergency plumber in Cornwall at night?

07879 234479, 24 hours. The office line, 01726 821 559, is open Monday to Friday, 8am to 5pm.

How do you find a leak without pulling the floor up?

Pressure testing narrows it to a section of pipework, and from there the location is a small area rather than the whole run. It is the difference between lifting one board and lifting a room.

Can underfloor heating go into an existing house?

Yes, though retrofitting into an existing floor is a bigger job than laying it in a new screed. Floor height, insulation underneath and the heat source all change what is possible, so we survey before quoting.

Do you clean and disinfect commercial water storage tanks?

Yes, including the records your water hygiene file needs. It sits alongside the rest of the commercial water services we handle.

How long does a new bathroom take to plumb?

Five to ten working days for a full bathroom, depending on whether walls move and whether tiling and electrics are in the same programme. We handle the electrics too, which keeps the programme in one place.

Do you fit unvented hot water cylinders?

Yes, in homes and in commercial buildings. Unvented cylinders are notifiable work and the discharge arrangement is where most problems are found, so we install, test and certificate the whole thing.
