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.

If you are looking for a caring and conscientious builder then look no further than Stephen. Not only is he on your side for your project and budget, he gets the job done with absolute attention to detail. He works incredibly hard and is not satisfied till you, the client, are happy. He has a photographic, encyclopaedic memory for all things building and structural. He, with his extensive experience, is worth more on your project than any architect plans or drawings. Not only is he damned good at what he does, he’s polite and thorough. He also has a fantastic team that he keeps a close eye on at all times. There are no loud radios or requests for coffee. His team have a fixed break/lunch, bring their own supplies and I’m embarrassed to admit, leave your house tidier and cleaner than when they arrived - even when doing excavation/structural work! I offer only one word of caution, once Stephen and team are in, you won’t want them to leave, and you will start asking him to do all those other building jobs you never knew you wanted done! You will be very fortunate if you can secure him for your project. You can complete confidence in him, his team and their work.

We were absolutely delighted with Lino and his services. He was incredibly patient , as our flat purchase was delayed. We required a total gutting off our flat, with new kitchen and bathroom, new flooring, painting, and all the rest. He had great communication throughout. He showed up on time with his team each day , and was so professional throughout. We went to Lino for advice throughout the process. He never said any of our plans were not possible- he always either said yes, or provided another option. This was such a great help. I would recommend Lino to anyone. We are absolutely delighted with our flat.

I've used Facundo's team to install a new shower, including wall and floor tiling, massage jets, and concealed shower equipment. Facundo was the person we dealt with at all times, although someone else was assigned to do the job. The quality of the work and finish is extremely good. I was also impressed with Facundo's professional attitude at all times, being very polite and respectful, as well as proactive in addressing any potential issues affecting our planning and execution. Highly recommended.

Conversions - General- 10 May 2020
Great job undertaken, all work completed to a high specification and quality. The workers always discussed any items that came up to make sure I got what I wanted. In specing up the job William was very helpful and proactive in assisting me finding the right materials (specific bricks in this case) and managed getting all materials to site in these tricky times. Work areas were always left clean and tools stored away (important with young children) Wouldnt hesitate to use again for any other building works.

Pawel worked on my son's property in Notting Hill, London. The final result was absolutely wonderful. I found Pawel incredibly helpful, skilful and willing to change things last minute, as I procrastinated over every job! He left the property clean and tidy each day, and the end result was a flat that has been transformed and improved beyond recognition. I would thoroughly recommend Pawel and will definitely use him again in the future.
