Restoration & Refurbishment- 8 Jan 2026
I’m extremely happy with the work carried out by Arindo @ Altd Carpentry. From start to finish, the refurbishment was handled in a very professional and organised manner. The work was completed on time, exactly as agreed, and the quality of workmanship throughout the house is excellent. Everything from the kitchen installation, flooring, tiling, carpentry, electrics and painting was done to a high standard, with great attention to detail. Communication was clear throughout the project, and any questions or small changes were dealt with promptly and without fuss. The site was kept tidy, Arindo was respectful, and it’s clear he and the team take real pride in their work. I wouldn’t hesitate to recommend Altd Carpentry to anyone looking for reliable, skilled, and trustworthy builders. I would happily use them again for future projects.

I recently used PrimeUK Contractors Limited for conversion works at our studios in Camden, and I couldn’t be happier with the results. The project timeline was set at six weeks, and the team delivered right on schedule. Pavlo and his team had a clear understanding of the scope and what needed to be achieved, going above and beyond to make the project a success. The quality and attention to detail in their work were outstanding, and my entire team was thrilled with the final result. Their pricing was competitive and fair, which was another bonus. When we have more work in the pipeline, Pavlo and PrimeUK will definitely be my first call. Highly recommend!

Handyman- 6 Jan 2026
Firstly, I havent used mybuilder in years, and I hired Zaim hoping for a good job on our dining chairs. I can safely say I was very suprised. He did an excellent job. From the moment we talked he had great communication, he was timely and said he would call 30 mins before arrival which he did, he spent time fixing the legs of the chairs as if he were doing the work in his own home. He is also not afraid of letting you watch him work, he has nothing to hide and is genuinely a nice person. He wants to do a good job and doesn't leave until the room is in the condition it was in before he came, he even hoovered up afterwards. Zaim was professional, calm and knowledgeable. Some people do a rush job, but you could see he wanted to do a job that was good, even redoing work because he wasn't happy with it. A solid job. Would certainly recommend.
