Report
I phoned GK in the evening as our shower died...not convenient in a house with 5 people! A quote was sent the same evening, with the shower ordered and fitted by lunchtime the next day. Fab tidy job. Gareth kept me updated throughout and was really responsive to my messages - not easy to find from a company. Thank you for the professional and speedy service

The service was excellent from the initial meeting to measure up for a new sink and unit to the installation. Very polite and professional. Would definitely use GK plumbing again and recommend them. The whole experience was first class.

Cannot fault the G K team, big installation was done with minimal disruption. We were kept up to date with all works, they incorporated last minute changes to spec on our part with no fuss. Overall we are absolutely delighted to have chosen G K. Every member of the team top class & professional throughout.

We've used GK Plumbing for a number of projects. This time it was for removing a bath and shower and replacing them with a walk-in shower. The quality of work was excellent and completed in good time. Thanks to Dan for coordinating the project and to Matthew for his meticulous work as the inevitable adjustments had to be made.
