Hard Flooring- 2 Oct 2026
Really happy with the flooring work from Remus. He fitted engineered wood flooring in my home office, including removing and disposing of the old carpet, fitting new boards, laying plywood underneath, removing and refitting new skirting boards and painting the room. It wasn’t a straightforward job as the existing floor was uneven and there were gaps around the old skirting but Remus dealt with these and left everything looking neat and well finished. The end result looks excellent and has made a big improvement to the room. Remus was easy to deal with, timely,helpful, and clearly cared about getting the finish right. I’d definitely recommend him to anyone looking for a decorator.

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.

Groundwork & Foundations- 7 Feb 2026
Oli carried out the groundworks and demolition at my property and was on site every day with his crew, fully committed and hands-on throughout the job. I am an architect, and this was work on my own home, so my expectations were high. Oli met those expectations fully. He has a strong knowledge of groundworks and demolition, works carefully and methodically, and you can tell he genuinely enjoys what he does and takes real satisfaction in delivering the work exactly as required. He was always in a good mood, easy to communicate with, and a pleasure to have on site. I enjoyed discussing the project and hearing about other jobs he has completed over his 23 years of experience, which clearly shows in the quality of his work. I would highly recommend Oli for any groundworks or demolition works.
