Restoration & Refurbishment- 18 Apr 2026
I had my bathroom fully tiled and refurbished by Mr Madan and it was done with patience and professionalism. My house is 1930s build and it comes with its own challenges when doing a project, but Mr Madan dealt with every challenge, whilst keeping my costs down. I'm 100% happy with the end result and I will highly recommend him.

Extension Builder in Berkhamsted
I am a builder with 20+ years of experience, which has allowed me to specialise in pretty much every field of the sector; from tiling to fitting kitchens and bathrooms to painting etc... I am very meticulous in every job I do and always try my very best to please costumers. What I believe makes me stand out from other tradespeople is that I acquired most of my experience in Italy which is where I lived before moving here 4 years ago. This has helped me achieve different techniques and skills.
