Extensions- 30 Nov 2020
A really excellent set up of builders. Peter was great in evaluating the work and what we needed done. Sue was clear in her communication on costs, and then execution of the works by Taras and his team was superb. The extension was built in fantastic time-frame, and the end result is great. The work-ethic of the builders is what really makes them so good. They are on-time every day, and relentless with working hard each day.

We completely renovated our home, which included building a new side and back extension. Mr. Manaj did a fantastic job installing new plumbing, decorating, new flooring with heating, suspended ceilings, a new kitchen, and partition walls. We are overjoyed with how beautiful the house has turned out. Mr. Manaj was really competent and dependable; the work was completed on schedule, and I would highly recommend him as a worker. We are pleased to send you any photos of Mr. Manaj's outstanding work.

Extensions- 13 May 2026
Agim completed a ground floor extension for me in 2025 and I would not hesitate to recommend him for similar work. The quality of the work was excellent and the team worked tirelessly for months to ensure it was completed on time and for a reasonable price. Agim was able to adapt quickly when any unforeseen problems occurred, always clearly communicating possible solutions to help keep the project moving. Having people in your home can be difficult but Agim is very respectful and considerate, making sure to put our needs first. The results are fantastic and Agim continues to help snag any minor issues that come up. I couldn’t be happier with how things went, testament to his professionalism. Thanks Agim for all your help on this project.

We needed a rear extension built with an internal courtyard. From day one when we first contacted Mert to get a quote he was professional and easy to talk to. His quote was good value for money. During the job he and his team were approachable, careful with our property and always easy to talk to and answer questions we had. The work Mert did was fantastic and our neighbours have already gone on to use him. We will get him back again for more work and highly recommend him.

Replaced a rotten external single door. The existing door frame was reused, as per request. This frame wasn't perfectly square which Alex had to compensate for. Alex arrived on time and completed the work without any unresolved issues, taking all offcuts and old door away for disposal.
