Extensions- 15 Oct 2023
Outstanding Porch Replacement Experience! I am writing to express my utmost satisfaction with a porch replacement carried out by Harpal and his team (Vinod and co). From start to finish, the entire process was seamless and incredibly professional. First and foremost, the craftsmanship displayed in the construction of my new porch is truly exceptional. The attention to detail and precision are evident in every aspect of the design. The porch not only looks stunning but also feels incredibly sturdy and well-built, a testament to the high-quality materials and expertise of your builders. Moreover, I want to commend you and your team for their exceptional customer service. They were always punctual, polite and attentive to my concerns. Any questions I had were answered promptly and the team went above and beyond to ensure that I was completely satisfied with the end result. The project was completed within a reasonable timeframe and the site left impeccably clean upon completion. I appreciate the professionalism and efficiency demonstrated by your team throughout the entire process. I would wholeheartedly recommend Harpal's (Pauls Building Services) services to anyone in need of a porch replacement. Thank you, Harpal for transforming my outdoor space into a beautiful and functional area that I can enjoy for years to come. Your dedication to excellence has made this renovation experience truly outstanding.

Works consisted of hip to gable loft conversion under permitted development and a refurbishment of the first floor of a semi-detached house into a four bedroom/bathroom layout, including new windows, balconies, wiring and plumbing as well as sound proofing the walls. With 100m2 of works this was my first introduction to a major building project and I was worried by the horror stories I have heard about builders. From the outset Monika set my mind at rest, listening to what I wanted, making helpful suggestions, offering tips for instance on how to save on the scaffolding and always asking me when choices needed to be made. She took the trouble to ensure that I knew what was happening, with daily photos of progress without the need for me to climb scaffolding. I was working to a tight timescale and budget, which Monika understood, and even having accommodated a number of changes including some additions, the project came in on time and on budget. All of the workers on the site were very professional and the quality of the work and the attention to detail was exceptional. I have no hesitation in recommending Monika and her team - I went into this project apprehensive and not sure what to expect; thanks to Monika, I came out the other side delighted by and looking forward to working with her and her team again to renovate my ground floor.

Emanuel and his team have delivered the project despite Covid-19 challenges and our changing requirements. We have changed our mind about design and finishes a few times during the project, and LIO were there to listen, advise and deliver. The communication was excellent throughout the project, and the works were finished on time. We will use them again.

Extensions- 26 Jan 2023
From first meeting Andy I got a good feeling, turned up when he said he would to view the job, provided an estimate very quickly too, based on the initial drawings. Once the final quote was agreed, (after structural calculations) other than additional works that were required (outside of Andy’s control) there was no overrun at all. All this during a time of hugely increasing prices. Throughout the build they used good quality materials and didn’t try to reduce his costs, right down to the paint upon decoration. Offered help and advice on other parts of the build that I was taking on myself, and we are very happy with the finished extension. There was an overrun on proposed completion date, but Andy tried to keep me updated throughout, I also have no concern should I ever need to call Andy back for any issues, but don’t expect that to be needed. Thanks Andy and team.

Decking- 26 Apr 2019
James and his team did a great job of relaying my patio and I would highly recommend them. The job was particularly tricky as I live in a terrace house so all materials and rubbish had to be brought through the house. They were extremely careful and very mindful of this and did a great job tidying up afterwards. I am very pleased with the result. They were all very nice guys and also came out reasonably priced versus other quotes I’d received. Cannot rate highly enough.

Fencing- 9 Jun 2020
To say we are delighted with the results from Beni The Builder, is an understatement.They did an excellent job building a substantial retaining wall using railway sleepers and installing a new fence along the top. They also helped collect materials which enabled us to start the work sooner. Extremely capable and competent team, arrived on time and left the job site clean and tidy after completing the works. They dealt with some difficult ground works easily and expertly. Price was competitive and the quality exceeded expectations. I have no reservation recommending Beni The Builder and will invite them back for some projects we have planned in the near future.
