Conversions - General- 28 Jan 2025
We were absolutely delighted with Lino and his services. He was incredibly patient , as our flat purchase was delayed. We required a total gutting off our flat, with new kitchen and bathroom, new flooring, painting, and all the rest. He had great communication throughout. He showed up on time with his team each day , and was so professional throughout. We went to Lino for advice throughout the process. He never said any of our plans were not possible- he always either said yes, or provided another option. This was such a great help. I would recommend Lino to anyone. We are absolutely delighted with our flat.

Restoration & Refurbishment- 16 Feb 2018
Adam and his team did a brilliant job! My flat was in very bad condition. They gutted the whole flat and refurbished everything to a very high standard. Work performed included, new boiler and radiators installation, complete refit of bathroom and kitchen including all tiling, plumbing and electrics, new spotlights and wooden flooring throughout, new doors and skirting boards and all painting and decorating. They also arranged for all skips and rubbish clearance. I simply left the keys with Adam and he performed all work with minimum guidance. I would touch base a couple of times every week or when things needed to be discussed. He was happy to purchase most materials and provide receipts. I would highly recommend Adam and will definitely use him again for future work.

Restoration & Refurbishment- 29 Mar 2018
A pleasure to deal with . Agim and his team worked hard to a very good standard.They often worked later than i would expect so that they were ready to move onto the next stage of the job the following day. Agim was very knowledgeable of all building regulations and was ready to offer me solutions when they were needed. All his team were courteous , polite and also knowledgeable. This was the first time I have used A&B but I would have no hesitation of using them again and recommending them to others.

The job was a complete refurbishment of a one bed flat, including rewiring and re-plumbing. We would recommend Al and his team without any hesitation. From the very beginning and all the way to completion, we felt very lucky and fortunate to hire them. We found them to be very hardworking, conscientious and professional. The job was a difficult and complex one, but the team still completed within time and within budget. Al's advice made the whole process easier and we found him to be very trustworthy and honest. The end result was better than we originally hoped for and was done to a high standard.
