I am delighted with my dining room extension. Lance Marshall promised me that he would finish on time and on budget - and he did. He and his son and one other helper worked like Trojans, with only the odd cup of tea/coffee to sustain them. I would unreservedly recommend them.

Extensions- 3 Oct 2020
WOULD NEVER USE AGAIN. WE HAVE PAID OUT OVER £3,500 TRYING TO RECTIFY THE MESS GLEN LEFT AND IT'S STILL NOT SORTED. HE'S AVOIDED ALL CONTACT AND BLOCKED OUR NUMBERS SO WE HAVE NO WAY OF CONTRACTING HIM. The build overran, but this was mostly due to Glen's hugely unreliable labourers who turned up sporadically. The carpentry workmanship was awful but our main complaint is the horrendous and ongoing issues we have had with our roof. Towards the end of the project there were several leaks in the roof which Glen 'rectified' at the time. We had to repair and repaint the ceilings that were damaged though. Since Glen left site, we have had other leaks from the roof, including the ones that Glen had supposedly fixed. At our own expense (because Glenn would not reply to our messages) we contracted a roofer to diagnose and repair. The builder was astounded to see what a mess the roof was and that the supposed repairs were just silicone to patch over poor workmanship. We have to date spent £3,500 trying to locate all the leaks in our roof and get them repaired and as soon as one problem is resolved another springs up! We are currently living with a giant hole in our kitchen ceiling (leaving us cold) until all the issues are resolved. We have had so many sleepless nights when it's been raining - please do yourself a favour and avoid. We have no idea where the spiralling costs will end and Glen has washed his hands of us and the mess he has created.

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.
