Raghbir did an excellent job and completed the work on time, exactly as agreed. What stood out most was his honesty and professionalism there were no hidden charges or unexpected costs, which can often happen with some tradesmen. He also didn’t cut corners and delivered quality workmanship throughout. I would highly recommend him for any carpentry work.

Costal has done a great job. I wouldn't say he was the cheapest quote but after reading the reviews we hired him because of his reliability. I found him reliable and always turned up when we needed during the project. He recommended us other contractors and supported us to achieve the goal we were trying to achieve. I would recommend Costel 100% if you want to have reliable builders for your home. Thank you

Extensions- 15 Sep 2022
Besim and his team carried out some structural steel work on our home while we were away. I was a little nervous about this but the communication was excellent, as Besim sent regular pictures and updates on the progress. The completed work was first class and the team even did some small jobs outside the original remit which was a very kind gesture. WIll certainly use Besim again and would highly recommend him to anyone.

Restoration & Refurbishment- 20 Oct 2022
I contacted Korab to remove my chimney breast, he came to have a look, quoted me for the job and then started the work. Once the work was completed I was over the moon with the work that Korab and his team had done and the service they provided and I asked them to have a new full refurbished house (new electrical work, new plumbing, new plasterboards, new skimming, new doors, new laminate flooring, new tiles, new skirting boards,new bathroom), side extension (which korab helped me to design)and garden patio and a new front garden wall. Korab was a very friendly and easy-going person from the moment I met him in regards to my first project (the chimney breast). He would pay attention to every detail and always ask if I was happy with the work which was being carried out. Korab and his team would always ensure that the work space was left clean. Korab and his team were more than happy to have an input and make suggestions when I needed them too, he also make me feel comfortable to ask any question. Korab and his team did an amazing job in my house and completed the work to a high standard in which I was so happy about. They truly are an experienced group of guys and I would highly recommend them to anyone. What a pleasure it was to have met them. Thankyou once again!

Bathroom Fitting- 2 Jun 2026
Amazing work, Sam and his team are dedicated professionals that have real eye for detail. The toilet needed changing position which required a significant amount of rework of pipes. But they made it look easy.. tiling work was done perfectly and Sam helped me find the right products before starting this project. Really happy with the work done and was completed in a timely manner. Highly recommend.
