Plastering- 26 Jun 2016
We hired Manu and his team to plaster our summerhouse, relocate two radiators and fit a new bulkhead ceiling in the lounge and install LED tape. He was knowledgable, professional and considerate and I highly recommend Manu and his team. Not only did he understand the project for the bulkhead, but he came up with another suggestion which we went with, and friends and family agree looks amazing. The finish on the plasterwork is perfect and Manu and his team worked hard and even left the summerhouse cleaner than when they started! It is great to work with a team who pay such attention to detail, listen to the client and get the job done to a high standard. It was a risk to go with Manu as he didn't have any feedback when I hired him. I actually got him to quote so I could compare prices with someone else I had in mind to do the job, but when I met Manu I felt he would be the better person to do the job as he listened and understood exactly what I wanted and so I ended up hiring him instead. I wouldn't hesitate to hire him for any future jobs. Thank you Manu and team!

Extensions- 25 Apr 2025
we recently had the pleasure of working with Leon building contractors limited, and i cant recommend them highly enough! They carried out a single story rear extension, an internal garage conversion and porch to the front of the house. On top of that they installed our new kitchen and toilet suite downstairs all finished to a high standard. From start to finish Vic and his team were amazing nothing was too much trouble and were always happy to do anything without a fuss. Their attention to detail was first class. It wasn't only us who was impressed but our neighbors commented how friendly, respectful and hard working they all were and have already asked for his contact details. Vic trade contacts also helped us with windows/bi-folds and quartz worktops all high quality at much cheaper prices i could find myself! Thanks again to Vic and the team for doing such a brilliant job, we have no hesitation to use again in the future!

Extensions- 8 Dec 2021
Me and my wife are very satisfied with Prabbuilders work. What stands out with Prab builders is that they do every task as if they are doing it for their own house and with work they are meticulous and exceptional. What we started with and how our extension looks now is simply amazing and the way they explain about what will look good(Color/ the structure etc ) is commendable as we both were not sure what decision to make, but after completion we are overjoyed to see how excellent it turned out to be now. I would recommend them anytime based on their skill ,eye for detail, being punctual and the hard-work they invest into every task to make sure we are getting the final product the way we dreamt of.
