Carpentry- 28 Jan 2026
Ali did an exceptional job designing and building our staircase, and I couldn’t be happier with the result. From start to finish, he was a complete gentleman — polite, respectful, and a pleasure to deal with. Ali is clearly a true specialist at what he does. His knowledge, attention to detail, and confidence in his craft really stood out. He was able to design and install the entire staircase in just one day, which was genuinely impressive given the quality of the finish. He worked efficiently, kept the area tidy, and took great pride in his work. It’s rare to find someone who combines skill, professionalism, and good nature so well. I would highly recommend Ali to anyone looking for a high-quality staircase installed by a true expert.

My house was old and its condition was poor. Much were needed to be fix. The original kitchen layout were also inconvenience to my wife. I need to have all these changed under limited time. This builders have a team of specialists on almost every aspect. They gave me variety on the layout design and choose of materials. This saved me money, time and tons of trouble to find difference contractors. The after service and their respond time are very good too. I hope by sharing my happy experience can save your money and trouble to find a good contractor.

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.
