My boiler was faulty this morning. Armand was quick to get to us just before noon, figured out the issue, arranged the part to be picked up and was back within 1-2 hours to carry out repairs. Works lasted for 1 hour. He fixed the problem was extremely helpful and polite. Thank you so much. I recommend to anyone who has any issues to do with regards to boiler repairs

Excellent experience, highly recommended! I called on Friday morning and had an engineer come over on the same day, identify the issue, find a replacement part and come back on Saturday to fix the boiler. Great service, I will use again.

Armand did a fantastic job - I needed two radiators taken off the walls before I had damp proofing done then replaced again afterwards. He was easy to communicate with, very professional and able to do the job quickly. Would definitely recommend.

Did a really great job fixing the bathroom. We had a leaking bathtub and moldy grouting. Took care of the leak very quickly and professionally, and re-grouted the tub as well. It all looks as good as new!

Pete French Designation

Very good service. Initially I simply had my bath taps replaced, but I then also had a heated towel rail fitted (which involved a full drain of the central heating), and both times I feel the job was done excellently. Both jobs done fast and efficiently, well within the quoted time, and left the place clean and tidied as well. Would definitely use any time I need to have any more plumbing work done.

Alys Wang Designation
