Restoration & Refurbishment- 4 Sep 2020
Octavian is a really great guy, very reliable, never disappoint, maintained good communication with us all the time. As a customer, obviously the most important part is great craftmanship, we have used other teams before and you can easily tell the difference between his work and the others. From things such as painting (you can tell they have paint and sand multiple times to provide such great finishing), tile installation (the gap between each tile is tiny, and they are very flat), Octavian’s team can get them all done. This job involves a full flat refurbishment, so the flat was completely stripped, knocked down a few walls, install new pipes / wire etc. During his work he has spotted many things that we have not noticed before. Unlike some other contractors who do not care, they will just finish what they were asked to do and leave. Octavian spotted it and recommend us the best solution for it, to provide the best outcome for the project. It is important to find someone who do care about the customer and the project. We will use him again for our future projects. Thanks. Tommy

Tommy was a wonderful perfectionist and has done beautiful work in our stairway and hallway which had needed refurbishment for a very long time. It feels brand new. The flooring is perfect both in the hall and staircase, and the walls are now perfectly smooth and painted immaculately.

Emir did a good job. The company did a bathroom refurbishment after water leak, repaired the damaged ceiling downstairs and painted the room. Emir’s attention to detail is very good and he went the extra mile to do the job properly. I will recommend his services.

Restoration & Refurbishment- 16 May 2021
TLC have completed the first phase of the project which has involved a complete renovation and upgrade of the kitchen, bathroom, and rear garden area. A new contemporary staircase has also been fitted. The work has been completed well ahead of schedule, and this is testament to the planning and coordination skills provided by TLC. All of the work has been completed to a very high standard, and a great deal of care has been taken to ensure the minimum disruption to the local residents. We are extremely grateful for the advice and support provided to us leading up to the restoration work and whilst the restoration was underway, and we are absolutely delighted with the final results. Our house has been transformed into a contemporary family home. Many thanks to Bradley, Paul, and the rest of the team at TLC.

Excellent service and outstanding workmanship! I recently had my bathroom renovated by this company and I couldn't be happier with the results. From start to finish, they were absolutely professional in every way. The quality of their work is truly perfect - they paid such close attention to detail and did an amazing job with everything. What's more, the price they quoted me was very reasonable and they stuck to it without any hidden costs or surprises. The whole process was smooth, efficient and stress-free. I would highly recommend them to anyone looking for building services - they really are top class and provide excellent value for money. Thank you for such a fantastic job! To Abdullah and his team.

I recently had a full kitchen installation carried out and I’m really pleased with the results. From start to finish, the work was completed to a high standard and everything was done with great attention to detail. The installer was professional, punctual, and easy to communicate with throughout the project. Any issues or questions I had were dealt with quickly and clearly, which gave me confidence that the job was in good hands. The workmanship is excellent – everything is level, neatly finished, and exactly as discussed. They also kept the workspace tidy each day and made sure everything was cleaned up properly once the job was complete. The kitchen looks fantastic and has completely transformed the space. I would happily recommend them to anyone looking for a reliable and skilled kitchen installer, and I would definitely use them again for future work.

Plastering- 4 Oct 2024
Mr Rifat did an excellent job for plastering rooms and i would recommend him to everyone highly. The work he has done is to a very high standard and completed in 3 days. His quote was very helpful and comprehensive and he was helpful and very kind and calm. He did not take a break from doing the work, even though i told him to take a seat for 5-10 minutes. He is a very hardworking person. I think anyone to catch him to do a job for themselves is very lucky. I recommend him to everyone because he knows how to do good job.

Tiling- 24 May 2026
I cannot recommend John from Pacho Create Ltd highly enough. I'm a very particular client with high standards, I was impressed by his care, patience, and professionalism throughout. He clearly takes pride in delivering quality work and paid close attention to every detail. Living in a small flat, I was concerned about dust, but John proactively created a solution to minimise disruption, which I really appreciated. He also gave excellent advice on budget-friendly waterproofing products. We had a challenge with large-format tiles, but John worked closely with me to plan the layout, ensuring a natural, balanced finish. The workmanship is outstanding – minimal wastage, precise alignment, and superb attention to detail. I wouldn’t hesitate to use John again, in fact, I’m already planning to have him back to tile around my bath in the near future. I highly recommend him to anyone looking for a skilled, reliable professional.

Latest review:
We initially hired Michael to convert a bathroom into an office. After meeting him and discussing our longer-term plans, we quickly felt confident moving forward with him on much wider renovation works across the property. Michael worked closely with us throughout the entire process—from early ideas and structural planning through to execution. He consistently provided insightful, practical advice that added real value. His ability to anticipate issues early not only prevented problems but also helped us save money by refining the plans to maximise our goals and avoid unnecessary costs. Michael’s broad knowledge and skill set were hugely beneficial on a project of this size and within a tight budget. He made the process far less stressful and, at times, genuinely enjoyable. He kept me informed and involved at every stage, which gave me a great deal of confidence in both the quality of the work and the decisions being made throughout. Michael helped us renovate every corner of our four-bedroom maisonette in West London—from bathrooms and structural opening-up works to a full kitchen renovation, hard landscaping, flooring, and carpentry. The list goes on. His wide skill set and depth of knowledge were truly impressive and exactly what we needed, particularly as we chose to stay closely involved in the renovation rather than hiring a larger construction and project management company. We genuinely don’t feel we could have made a better choice. It’s not always easy to find a builder who is reliable, honest, and trustworthy, so I feel very fortunate to have worked with Michael. I would recommend him without hesitation and will absolutely continue to work with him on future projects, big or small.
