Windows & Doors (uPVC & Metal)- 4 Aug 2026
Rubin and Sahil are both con men, STAY AWAY FROM THEM. My job was to fit a 29 windows and 6 doors, the quote was average. When they came to look at the job they sounded like they know their stuff. But they know shit. Having to redo all the windows, kicked them off site. Taking money everyday. STAY AWAY.

Bathroom Fitting- 14 Nov 2019
We had our bathroom completely refurbished and Graham the owner was lovely. He came to give us the quote, visited whilst work was being undertaken to make sure everything was okay and came to make sure everything was finished to how we wanted it. The work carried out was of a high standard and whilst the bathroom work was being completed we also ended up getting our kitchen worktops done by Graham’s team. Chris was the one who carried out our work, he was very friendly and checked we were happy with the work he’d done before he left everyday. I would use Graham again for other work needed around the house.

Extensions- 17 Jul 2020
Orgert Myrta and his highly skilled team did an exceptional job renovating our Victorian terrace house in under 8 weeks. On meeting Orgert, his warm, friendly and professional manner was reassuring. I immediately thought he was someone I could work with. His initial assessment of our house, he advised on best possible solutions to achieve our aims within budget. He invited me to visit the homes of his recent previous clients & obtain their feedback, which I did. Visiting two clients, they both spoke highly of Orgert & his team, sharing their positive experience and how Orgert has since completed work on their neighbours homes & family members homes too. Judging by the quality of work completed in both client's properties, I knew Orgert was the right builder for me. Responsive & prompt throughout, good communication, providing weekly status updates, even advising on where to source great deals on second fitting items saving us money. To say we are pleased with how well the project has gone & level of workmanship is an understatement! Without hesitation we highly recommend Orgert & his team, who since finishing our house are now doing work on my relatives house. Orgert & his team completed in our home: - Rewiring & new plumbing - Plastering walls & ceiling - Replace old ceilings - Painting & Decorating - Painted exterior front & back - Replaced & repointed brickwork - Installed new kitchen & bathroom - New flooring throughout
