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.

Carpentry- 10 Aug 2023
you will see I ask for experts in my job posting because my desired outcome of this job was quiet floor as you walk across. I hired LTDinchev and the 2 gentlemen were helpful, pleasant and friendly. The job was completed for the price quoted and in the time specified. my only disappointment is after the job was completed I still had SOME of the same floor noises. so although they work hard on my subfloor I did not get 100% my desired outcome.

Plastering- 8 Jun 2026
We were thoroughly pleased with Bathroom Renovation, Bahram and the services provided. We required stud walls throughout our apartment, ceiling replacement and ducting/pipework concealing. I can only say that Bahram and his communications have been a breath of fresh air. The team are efficient, friendly and get the job done - most importantly Bahram takes pride in the work his team complete. Our job was relatively urgent and Bahram offered what I feel was a fair price, remained communicative and had his team readily available to get the job completed within the timeframe. Most importantly, as with it seems all building works, jobs can grow slightly, but Bahram’s considered approach and advice was invaluable. We increased the scope of our works mid-job, and are really pleased with the results. Fair pricing, someone who has pride in their work, and a job well done.
