Extensions- 23 Feb 2024
I’m literally blown away by this team of guys. Professional from start to finish. Danny quoted promptly in the timeframe he promised after he viewed the project. He was clear about what he could deliver with the budget that I had and made suggestions using his knowledge that helped me achieve the dream garden room that I have always wanted. His team turned up at 8am sharp and work started at 8.01 every morning. It’s clear that Danny surrounds himself with professionals that he can trust to execute his promise and deliver the quality he expects, and that his clients pay for. Another plus is that he was extremely accommodating to some changes that I asked of him during the build which he also didn’t charge for. Nothing was an issue to this man and he clearly operates a “client first” attitude which was apparent also when he visited every second day to check progress and quality. Lastly which is also something that I didn’t expect is that he had the extra materials that were not used collected and credited to the final bill. If I had more time I could go on all evening but my final words are. Look no further. With Danny you have found an honest professional business man that takes pride in his work and I am happy that I found him and his team. Good luck with your project.

Fletcher and his team did a 5 metre extension on my kitchen, installed a new kitchen, new doors and new floorboards throughout the downstairs. All members of his team were absolutely outstanding. The workmanship looked extremely professional and it turned out so much better than I expected. If there was ever a problem, it was never a case of ‘we can’t do that’ there was always a solution and I never felt stressed as I knew that whatever cropped up, they dealt with it. They were all so friendly and I felt at ease with them all the time. When I went to work, I left them to their own devices and they always locked up perfectly for me. I can’t recommend them enough and I will certainly have them back when I need more work completing.

Bricklaying- 24 Apr 2019
Jake and Harry did an amazing job with our front wall and fence in the rear garden. We got three quotes for the job and they were the cheapest but also came across professionally. It wasn't a straight forward job, it was was using reclaimed materials that were varying size and shapes. I was also quite particular on the look, I wanted the brickwork to match our house, they took care to match the pointing and bricks but offered advice on how we could save money whist still getting the look we wanted. They arrived everyday on time, they were reliable, honest and extremely hardworking. They also kept us in the loop throughout the work making sure we were going to be happy with the end result. I have already recommended them to friends and will use them again for our next project. Thumbs up from us!

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.

Extensions- 9 Mar 2018
Kenny has just finished building a porch at my address. From the beginning, Kenny has been excellent with regards to providing advice, arranging the job to suit us and providing a very competitive and reasonable quote. Whilst on site, Kenny arrived early, was always extremely polite and the finished job was even better than we imagined it would be. On a scale of 1-10 we would honestly give Kenny an 11 and will definitely use his company again. Would definitely recommend him to others.
