We used then recently for a gas conversion but were left with a sour taste in our mouth after they sent us another bill for coming out to fix a leak caused by the conversion. Their response 'all care, no responsibility'. We will not be using them again.
The owner of this company will make a lot of promises about how good their service is, however when problems occur with contractors he has recommended, his attitude will quickly change and he will stop communicating with you. They also billed us before the job was completed and in our frustration had to hire our own contractor to finish the job. We also ended up paying the bill just to be rid of them although the job was not finished. For simple jobs these guys may be great, but not recommenced for bigger jobs that involve project management.
Well. They put in a basin in the bathroom. I bought the basin and it took three chargeable hours to fit it. Seems that they had a bit of difficulty, but fitting a basin is a pretty basic task for a plumber you would have thought.
