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!

Conversions - General- 6 Mar 2023
Jerzy was always pleasant to deal with. He gave a timely quote at a reasonable price, and was clear what was and what was not included. This price did not vary. Jerzy started the job promptly and despite some delays caused by the freezing weather and illness the job was completed to a good standard. Jerzy and his workforce were always respectful and trustworthy. I would use Jerzy again in the future for building work.

Conversions - General- 30 Sep 2020
Agim gave us a very reasonable quote for the removal of a chimney breast in our downstairs utility room. Although it's normally a very messy job, they took care to keep the amount of dust and mess to a minimum. Everything was finished to a very high standard, they didn't cut any corners or rush anything. I would definitely recommend A&B - they are an excellent, reliable company.

Conversions - General- 8 Oct 2022
Valentin, Dan and Chris did a great job turning an old wooden shed into a beautiful teenage den / home office. They stripped the shed down to the original wooden frame, replaced the roof and cladding, subdivided the internal space into two rooms and a small shower room. The job was reasonably priced though there was a little scope creep much of it due to additions to the original specification that resulted in an increase in price. With hindsight we should have made sure we kept track of additional work. They were friendly, tidy and considerate in the work and the dog loved having them around. They were professional and hardworking and we were pleased with the final result which was excellent value for money. We would recommend Valentin and his team and will have them back to do more work for us.

Electrical- 4 Jun 2025
The job went very well. An Envirovent 150 fan was installed with a separate thermostat and isolator switch, together with two 150 mm diameter inlet vents. It had to fit into a tight space, which took some care and careful fitting, but the result was perfect. Rob and Harvey are pleasant and diligent workers.

Joinery & Cabinet Making- 16 Dec 2022
I'm so happy with shelving that ozzy and his colleague made. Ozzy took the time to understand want I wanted (floating alcove shelving) provided a clear and comprehensive quote, and kept me updated on completion of the shelving in his workshop. On day of installation, the guys were lovely and friendly, they went the extra mile in dealing with floors and walls that aren't at all straight, and the finished result blew me away, it's transformed the space completely. Such a pleasure to deal with, would highly recommend and i would definitely use them again in the future.
