“Highly recommend Flow Medic. Our boiler stopped working meaning no hot water and my husband receiving hospital care at home. George came out and fixed the problem even though it was late in the evening. We've used him before and he always goes the extra mile to do a good job.”
Linda Linjon · Google review“Excellent service from start to finish. The plumber was punctual, professional, and completed the work to a very high standard. He clearly explained what needed to be done, worked efficiently, and left everything clean and tidy afterwards. The quality of workmanship was outstanding, and the pricing was fair and transparent.”
Augustine Osei Bonsu · Google review“These guys are super professional and reliable. Their advice is based on what is best for the customer and they have a we won't be defeated approach — no problem is too big or complex. The best plumbers I have worked with by a distance.”
