Kitchen Fitting- 19 May 2026
I’d advertised for my kitchen unit doors to be replaced as the old ones had started peeling off. Raj replied and said he would be happy to install the new doors for me…he even helped with the measurements to ensure I order the correct sizes…he turned up on the scheduled time and did a great job at a very fair price…on completion he cleared up the old unit doors and left the place clean and tidy…he is now in my contacts and will use again if required…thanks Raj 👍

Freddie, Kaz and Dan are a great team. I felt they were friendly and professional throughout. Any slight niggles were discussed and solutions found, quickly and professionally. They were respectful and went out of their way to get on with all the neighbours. Over all I would say they are a team of very nice people, who care about what they do and take pride in achieving the result their clients are after.

I couldn’t be happier with the work carried out on my home. The tiling on the ground floor, the laminate flooring upstairs, and the kitchen units were all completed to an exceptionally high standard. The attention to detail was outstanding, and everything was finished neatly and professionally. He was reliable, hardworking, and clearly takes great pride in his work. The end result looks amazing and has completely transformed my home. I would highly recommend him to anyone looking for quality workmanship.

Extensions- 3 Nov 2022
I hired Aras to prepare a Scope of Work document and organise three builders to visit and quote for the works (a side-return extension, and other internal refurbishment). I've been very happy with the work Aras has done. The SoW document was very detailed allowing the three builders to provide like-for-like quotes. He recommended three builders he's worked with before, and provided honest feedback and the pros and cons of each. Lastly, he's always been helpful in answering general design/structural questions I've had. I would definitely hire Aras again and highly recommend him.

I could not recommend Tim enough. From when he came to quote for the job to completion he was very professional. We had our whole flat painted and he and his work colleague did the whole thing in 4 days. He kept us updated as he went and suggested things that needed extra work or extra coats of paint to protect the walls better. I really was very impressed by Tim and am very happy to recommend him for your painting needs.

Couldn't recommend Domi & Emile enough. They have great building knowledge and kept us informed and up to date throughout the whole building process. The job was finished to a high standard and they even came back free of charge to tie up a few snags a few weeks later. Great builders and a great team!

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.

Bathroom Fitting- 9 Feb 2019
Alexandros did an exceptional job with our bathroom. As it was our first major renovation we were very anxious about the whole process but Alexandros made everything very easy and smooth from the beginning until the end. Alexandros has a lot of experience and he is full of ideas and good suggestions. The new bathroom looks amazing and we could not have chosen better than Alexandros. Alexandros was very helpful throughout the whole process. I would highly recommend Alexandros to anyone and we will definitely use his services in the future.
