Carpentry- 15 Aug 2025
I would 100% recommend John and his team. We have been really unlucky with 3 other builders taking off with our money and not completing the work. John is very professional, took on someone else’s mess and done a brilliant job. We wanted exposed oak rafter detail and the team done an excellent job. John is very good at problem solving on the spot when there are issues, he is very approachable and keeps you updated with the progress throughout the job. What he has been good at is also talking through different options with us before doing different sections of the work and he does not take short cuts. If you need excellent honest builders John is your guy! We will get the decorations done and post the end product.

Extensions- 2 Mar 2017
I used the firm's services to build an extension. Darek himself seems to be a hardworking and reliable individual. Problem is - he surrounded himself by some not very professional people, including close family members, who make things much worse for him. The other problem was that most of his team members do not seem to have much loyalty to the firm and are ready to jump to a different job any time. We had a terrible delays with our project and some things we had to completely re-do using 3rd party services. If you can ensure Darek is 100% committed to your job - could be a good project, if not - please await problems (just like I had)...

Bathroom Fitting- 25 Sep 2018
Mustafa is excellent! He did a fantastic job on our bathroom - so much so, that when we decided on a more extensive construction project, he was our first call. He is communicative, friendly, and hardworking. All his team are sweet guys and they did a great job for a great price. I cannot recommend him enough.

Painting & Decorating- 24 Feb 2020
Quite literally the worst tradesman I have ever worked within 25 years as a property developer! He came and quoted to paint my house (a good price I must say), little did I know that this meant he would spray everything that he can see, not prepare the surfaces by sanding them down or protects things. This included door handles, hinges, radiators, alarms sensors, tiles and my own furniture and cooking utensils. First time I confronted him about this he said that we would clean everything, and we agreed to carry own. However, it became apparent that we was doing the same as previously discussed. have paid hi 66% of what was agreed, I quickly realised that the damaged he has caused was going to cost me far more and I told him to leave. The next day he turned up at my house with his wife demanding the balance which I refused to give him, they were both shouting outside my house, threatening to call the police. I eventually agreed to pay the 50% of what was left, just so that they would leave. However, even once he had confirmed writing his acceptance of this, he walks over to me and threatened me one final time, saying that he will take me to court etc, there is god and he will see to me! I advise to stay away from this person, better to pay a little more and work with professionals who don't agree with one thing and do another. He paints using a spray, which means you can not touch anything up and he quite literally paints everything he sees!!

Extensions- 3 Sep 2013
Kel and his team worked on my single storey extension with bifold doors and glass roof. He also did some landscaping in my garden, replacing the fencing and installing a raised patio with cedar battens to the side. Overall I was very pleased with the work Kel did. He is a good communicator and frequently visited the site to keep on top of the work. Kel was happy to discuss requests and was flexible with design changes. The bulk of the work was completed on time with just some minor snags remaining, but the finish is excellent. It's been a long and stressful journey, but it's been easier with the friendly support and professional approach Kel has taken to his job. I'd be happy to recommend Craft of London and provide a reference on request.

Loft Conversion- 31 Mar 2026
We recently hired Altin to do our mansard loft conversion and honestly, it was a really good experience from start to finish. He was always on time, worked really hard, and his whole team put in a lot of effort every day. Communication was easy and straightforward, which made things much less stressful for us. The project was finished on time as agreed, and we’re really happy with the quality of the work. Altin was also super helpful whenever we had questions and helped a lot with building control, which made a big difference. It’s quite a messy job (cutting through the ceiling and putting in a staircase), but they did everything they could to keep things as clean and tidy as possible, which we really appreciated. Overall, we had a great experience and are very happy with how everything turned out. I’d definitely recommend Altin to anyone thinking about a loft conversion.

Bathroom Fitting- 7 Jun 2026
We recently had our bathrooms refurbished by Vasile and his team, and we are absolutely delighted with the results. From the very beginning, they were professional, reliable, kind, and exceptionally helpful. Vasile was always available to discuss every aspect of the project, taking the time to explain things clearly and answer our questions with patience and honesty. It felt as though we had a genuine partner supporting us through the renovation of our three-bedroom flat. Vasile and his team were fully invested in achieving the best possible outcome and were always willing to go the extra mile when challenges arose. The quality of their work is outstanding. They worked efficiently, kept us informed throughout, and ensured everything was completed in a timely manner without compromising on quality. We would wholeheartedly recommend Vasile and his team to anyone looking for skilled, trustworthy, and genuinely caring professionals.

Restoration & Refurbishment- 16 Feb 2018
Adam and his team did a brilliant job! My flat was in very bad condition. They gutted the whole flat and refurbished everything to a very high standard. Work performed included, new boiler and radiators installation, complete refit of bathroom and kitchen including all tiling, plumbing and electrics, new spotlights and wooden flooring throughout, new doors and skirting boards and all painting and decorating. They also arranged for all skips and rubbish clearance. I simply left the keys with Adam and he performed all work with minimum guidance. I would touch base a couple of times every week or when things needed to be discussed. He was happy to purchase most materials and provide receipts. I would highly recommend Adam and will definitely use him again for future work.
