Emergency plumber

Discovered a leak in my mains water pipe. Contacted Graham who sent Tom round first thing next morning and confirmed the problem was the mains pipe was corroded. Tom worked for four hours tracking pipes etc and solved the problem leaving no mess and a great job done to high standard. Would highly recommend this firm without hesitation.

Excellent job

I got Graham to do a full re-plumb and conversion from oil to gas. Turned up exactly when he said he would, very reliable and did the work to an excellent standard. Very easy to work with, honest and reliable, highly recommend.Daniel Dawson, Hillsborough

Totally trustworthy and a genuinely fantastic bloke.

We recently converted our oil heating to gas. It can be unusual to have a totally easy time with tradesmen but Graham did a fantastic job and we would highly recommend him to anyone. Before starting he was very clear about all the costs and work involved. He arrived when he said he would, kept us informed at all stages of the work, completed the work on time and was extremely clean and tidy throughout. He was also very clear in explaining the heating system to us after installation and we are completely delighted!

Brilliant Job

Look no further than Graham Wallace heating & plumbing if you need any work done. From first meeting Graham through to installation of a new Combi gas boiler, his advice and guidance was first class. His workmen were very experienced, friendly and courteous which made the whole process straight forward. There are always questions post installation - don't worry - Graham was on the end of the telephone to sort these. Overall a quality job, great team .... I've no hesitation in recommending Graham Wallace Plumbing and Heating.

Converting from oil to gas

Converting from oil to gas is a good move if done by the right people. I can highly recommend Graham Wallace and his team as extremely professional and dependable. Graham and Paul showed great patience and expertise resolving problems replacing an older house's previous system. Graham takes time to explain things and answer questions. I can totally recommend his guarantee of good workmanship.

Gas Installation

Finally made the decision to convert from oil to gas, my only regret, that I didn't do it sooner! Graham & his team 's professionalism shone throughout from start to finish, providing me with all the essential & necessary information I needed to know about todays's modern home heating system & how to get the most from it. I wouldn't hesitate to recommend him to anyone who was contemplating installing the gas system. Thank you for everything Graham!
