Painting & Decorating- 4 May 2021
On visiting to quote Andi impressed us with his professionalism so he was awarded the job over two other applicants. The job was completed on time and to an agreed specification. He was not the least expensive quote but we are happy that we chose him. If I had any further work I would happily employ him again.

Extensions- 4 Jan 2026
I hired Amrit based on positive reviews, but my experience was extremely poor. The work showed all the signs of a cowboy builder. I’m sharing this to help others avoid the stress, delays, and financial risk I went through. 1: No Respect for Contract or Deadlines Contract deadline was 15th September, which he completely missed. Despite delays, he demanded money almost daily. When I referred him to the payment and work schedule he signed, his response was: “I didn’t read it, I just signed it.” 2: Dangerous and Unprofessional Working Practices Brought in unqualified workers, many of whom could not speak basic English. He ignored safety standards throughout the project and wanted to use the same unqualified workers for gas work, which is extremely dangerous. When I objected, his response was: “Don’t worry, you will get a new house if it blows up as you have insurance.” 3: Work failed multiple building control inspections. He eventually refused to cooperate with the building inspector.

Latest review:
I engaged Edi to work on a full renovation and refurbishment of a 4 bedroom detached house with front and back gardens on Blackheath’s Cator Estate. Edi did an extensive amount of work, including stripping out; plumbing; plastering; windows installation; carpentry; and decoration. In addition, after commencing the property work, once the scaffold had been erected, following sensible advice, Edi and his team replaced the roof and fully insulated the attic; fitted additional electric points; rebuilt the garden patio; and replaced the flooring throughout, in addition to other important jobs including re rendering and pointing of chimneys, building new wardrobes in the main bedrooms; and upgrading the radiators. A new kitchen, and two new bathrooms have been fitted. The kitchen redesign meant knocking through a wall with the lounge to create a larger space. Edi is a highly skilled craftsman, who thinks creatively as he works to make best use of the space, including shelf fittings, and additional lighting for example. He has built some beautiful wardrobes, and the internal decorations have brightened up what was previously a rather shabby looking house. In addition to the above, I wish to commend Edi for his professionalism, courtesy, and passion for doing the best work possible. On all the site visits I attended, and every time I spoke with him on the phone, it was striking how much he cared about the work that he was doing, his desire to ensure that the house would look the best. I always left site visits with the feeling that he cared so much about the house that he could be safely relied on to give the best advice to enable us to make the right decisions. I also noticed that Edi and his team would take the upmost care to keep the property safe, tidy and in good shape throughout the project. He can be fully trusted to look after any site he works on. He is intelligent and careful when it comes to safety and security. It has been a pleasure for Edi and his team to work with us over a period of around 6 months, and he did so much to reduce the stress of a significant project so that we could always rely on him to work methodically, patiently and sensibly, and to make best use of the resources available. His pleasantness shines through, and everyone I know who has spoken to him has always provided me with the most positive feedback I have no hesitation in recommending Edi to anyone who wishes to engage him for future projects, and is most deserving of the good words that I and others that work with him have to say about him.
