Much of our work comes from repeat clients and recommendations
We have worked with Alkemsit Build and Decorate Ltd on a number of projects over the years, both large and small, including a house extension, loft conversion, and a full house refurbishment. From the very beginning, everything was handled in a calm, organised, and professional way. Communication was clear throughout, timelines were well managed, and we always felt informed and looked after. The team was reliable, approachable, and respectful of our home, which made a big difference, especially during longer projects. The standard of workmanship was consistently high, with real care taken over the details. Any questions or changes along the way were dealt with sensibly and without fuss, and we appreciated the honest advice and practical solutions offered.
Viktor has just completed a third property for me in South Kensington, London. He and his team have always been knowledgeable, hard working, went extra mile to complete a task. Good in advising whats best for certain work. I definitely recommend him and his team.
We had a large project done. Double-storey extension with a lot of steelwork, completely change the roof. All internal works, including decor on top of obvious plumbing and electrics, etc… all was done very well, up to a very high standard. Specifically, we were pleased with the following: 1. No budget creep – Victor (the owner) quoted the price and delivered it within the budget. 2. I was particularly pleased that the owner was on site every day in the morning and in the evening to check the progress 3. They handled build control all by themselves. Will be happy to hire them again for any kind of job.
This company has been the best in the last 20 years of our life experience. The combination of price and quality shows the best and fair option.

I can trust this company 100% and I have already booked a time slot to renovate our daughter’s house.
Victor and his team did an excellent job preparing my house for sale. They approached every task calmly and professionally, with a reasonable and transparent approach to costs. Victor’s experience with property matters was clear throughout, making the process smooth and efficient. Highly recommended.
We’re based in Elephant & Castle and had a wonderful experience with Alkemist. The work we had done included installing: an arch, paneling, coving and painting. It’s a 5-star job that has completely transformed our home. 100% would recommend, and they’re super friendly and respectful too.
Viktor’s team provided a very professional and thorough service in converting my loft into two bedrooms + a bathroom, and then went onto increasing the size of my living room, by knocking down a brick partition wall, then plastering and painting accordingly. The team carried out the work cost effectively and tidily. They worked in a clean manner, were considerate to my needs (I work from home), were never late to work (always started work at 8:30am, in line with noisy work regulations) & worked the whole day, without unprofessional number of breaks that many other builders take. They started and finished the work on time and were very flexible to my requests and changes in plans. Recommended!!
Victor and his team did a fantastic job refreshing my whole place: new kitchen, bathroom suite, repainting, and new floors. They worked incredibly hard, were super respectful of my home, and really listened. Whenever something needed tweaking, they found smart solutions, so the end result matched what I had in mind. Proper five-star service. I’d recommend them to anyone.

I had the great pleasure of working with Viktor and would happily recommend him.
First of all, he really listens to what the client wants. Even if something doesn’t come out exactly as expected at first, he fixes it without any arguments or unnecessary discussions and makes sure it is done properly. He is very reliable, cheerful, and pleasant to deal with. The quality of his work is excellent, and his prices are very fair and reasonable for the market. I would definitely work with him again.
