What You Think ...

"Taking off radiator to allow for plastering behind."

Great. I wanted a radiator off to allow new plastering behind. Both the chaps were thorough with taking care - no water spillage and were polite and courteous. They were very helpful in clearing the rubble behind the radiator (as the old plaster disintegrated during the process). Turned up when they said they would, did a great job, cleaned up afterwards. 10/10 all the way!

"Complete plumbing for a garden room and bathroom"

The design of the garden room is very traditional to fit with our Edwardian house. Doug Cowan installed the plumbing using traditional methods and traditional materials to produce what can only be described as a 'work of art'. We are delighted with the work and the finish. We have benefited from the excellent work Doug Cowan has undertaken for many years and have never been disappointed.

Customer, Fareham

"Completely New Bathroom"

Major project as completely gutted old bathroom and created new door to make "Jack&Gill" ensuite bathroom. Doug and his team did a great job; espeicially impressed as all the different tradesmen turned up on time (plasterer, chippy, electrican, tiler, floorer and of course plumbers). Always very cheerful and contactable and willing to discuss changes or instantly address any problem e.g. sorted bath when we realised wrong one was delivered.
