Bathroom Fitting- 2 Mar 2026
I can’t recommend him highly enough, in just three days, he identified and resolved my bathroom leak that could easily have become a much bigger issue. He took the time to thoroughly investigate where the water was coming from, clearly explained his findings and advised on the most sensible next steps before carrying out the work. From start to finish, his work ethic was exceptional. He arrived promptly at 8am every day and worked through until 6:00pm without a single complaint, no matter how demanding or time-consuming the job became. His efficiency was impressive but what stood out even more was the quality of the finish - the bathroom now looks brand new again. Professional, hardworking and meticulous in his standards, he delivered outstanding results in a very short timeframe. I wouldn’t hesitate to use him again or recommend him to anyone needing reliable, high-quality building work

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.
