Bathroom Fitting- 10 Jun 2026
I can't praise Cuban and Max enough. It's always a worry when looking for skilled tradespeople as you are putting trust in someone you don't know. My first meeting with Cuban filled me with confidence that he would do an excellent job which is why we chose him to renovate our bathroom. Paula was always available to answer questions and give advice on buying all the right fixtures and fittings to ensure the project ran smoothly. Cuban and Max were always punctual, respectful, polite and you can tell they have pride in what they do by the outstanding quality of their workmanship. Attention to detail is exceptional, and they both went above and beyond to transform our bathroom to something I thought we could only dream of having. I can highly recommend them for their professionalism and outstanding quality of work and finish.

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.

Extensions- 7 Mar 2026
Viktor is an excellent builder. He understands the needs of a complex job and mine was a huge renovation project. A side return and extension and full refurbishment of the house including the installation of 3 bathrooms, Kitchen, cupboards and much much more. It’s not quite finished yet but the house is transformed and the work was done incredibly fast, far faster than I had anticipated. I moved out for the duration but I was back in the house within 4 months. The language barrier made things a little harder than they might have been but we got by. If you have someone to project manage the job alongside Viktor I would suggest that but if you want someone who is really very good at his trade and runs a tight team I would recommend Mhilli Construction for your job.

We couldn’t be happier with the bathroom and toilet refurbishment carried out by Sahir. From start to finish, the workmanship was outstanding and the attention to detail really shows in the final result. The spaces have been completely transformed and finished to a very high standard. Sahir was professional, reliable, and respectful of our home throughout the project, always keeping the area clean and tidy. Communication was clear and honest, and everything was completed on time. We’re absolutely delighted with the results and would highly recommend them to anyone looking for high-quality refurbishment work. A truly excellent job!

Tiling- 25 Jul 2025
Shiv builders did the tiling for my bathroom. The quote was easy and done via a WhatsApp video. Price was reasonable. The job turned out to be more challenging than we first thought with uneven walls and floorboards were quite worn however they found solutions easily. The team arrived on time and did an excellent job. Always left the place tidy and very polite and professional. I then had a few additional jobs round the house such as changing door handles and fitting light pendants which they happily accommodated and again did a good job. Will definitely be using them for future work.
