I called in the morning to get an engineer to come and check our boiler which stopped working. Armand called me straight away to give me a free quote and send an engineer straight away. The price was really reasonable for an emergency call and very great service. Armand was also very friendly, caring and explained to us what was wrong with the boiler and what needed to be done. Would 100% use this service again and recommend

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.

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!

Isobel A Designation

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.
