Extensions- 13 Oct 2023
KBL recently completed a side infill extension for us that involved a lot of complex hurdles (e.g., requiring special foundations because of a Thames Water waste pipe and steel beams). In hindsight, we were very lucky to have hired them because they made the whole experience stress-free by explaining everything to us and handling our neighbours, contractors, structural engineer and building control for us. The amount of digging in confined spaces and hard, physical labour they put into this job is amazing. The extension looks great, is solid, warm and watertight. The wetroom they built inside it hasn't had any problems - plumbing is working great. Their plastering quality is excellent. We had to live in the property during the 4 months of construction but we felt relaxed and 100% trusted KBL to respect and care for the house. They have a lot of experience, know the building regulations, use quality materials and methods, they answered all of our questions with patience and always responded to my phone calls + texts quickly. They're so good that we'll give them an additional job to do which we originally planned for in spring 2024. Everyone we know wants KBL's contact details and we definitely want to ask them back for future work.

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.

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!

Bathroom Fitting- 21 Jun 2022
We are not entirely satisfied with Ludovic's work. Some of the tiles were not cut to the correct messurement which left big gaps in between. Worse still, the grouting was very messy and did not have a smooth finish. We will now have to get another Tiler to redo some of the tiling work. Overall, it was not a professional job and we are not very happy with his workmanship.
