Carpentry- 17 Dec 2024
James came up to have a look at the job and assured me it was no problem. He gave me an excellent price and a date to suit me. He and Billy worked really hard to get the job done as quickly as they possibly could, and I am absolutely over the moon with the results. We are already planning lots more jobs for the house. Would highly reccomend!

The job was to remove a stud wall with an archway between my kitchen and hall. Pawel was excellent from start to finish. He was good to communicate with before, and answered my questions fully. He turned up on time, was very neat and kept the noise down. He did a great job and cleaned up afterwards. I’d recommend!

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.

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.

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.

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.
