Testimonials
Viktor and his team have done a number of jobs for me, including a full refurb of a flat I rent out. I have always been impressed by the quality of the work that he has done, including building, plumbing and electrics. He is always very quick to start the work and has always been very cost-effective compared to other quotes I have received.
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!!
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.

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!
Amazing builders, super team and speedy work!
Great to work with Victor and his team. They’ve done a great job and will be using them again on more projects for our house.
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.
We are genuinely very pleased with both the process and the finished results. Alkemsit Build and Decorate Ltd is a company we trust and would not hesitate to recommend to anyone looking for a dependable, well-run building firm.
