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.
