Bathroom Fitting- 7 Jun 2026
We recently had our bathrooms refurbished by Vasile and his team, and we are absolutely delighted with the results. From the very beginning, they were professional, reliable, kind, and exceptionally helpful. Vasile was always available to discuss every aspect of the project, taking the time to explain things clearly and answer our questions with patience and honesty. It felt as though we had a genuine partner supporting us through the renovation of our three-bedroom flat. Vasile and his team were fully invested in achieving the best possible outcome and were always willing to go the extra mile when challenges arose. The quality of their work is outstanding. They worked efficiently, kept us informed throughout, and ensured everything was completed in a timely manner without compromising on quality. We would wholeheartedly recommend Vasile and his team to anyone looking for skilled, trustworthy, and genuinely caring professionals.

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.
