I couldn’t be happier with the work carried out on my home. The tiling on the ground floor, the laminate flooring upstairs, and the kitchen units were all completed to an exceptionally high standard. The attention to detail was outstanding, and everything was finished neatly and professionally. He was reliable, hardworking, and clearly takes great pride in his work. The end result looks amazing and has completely transformed my home. I would highly recommend him to anyone looking for quality workmanship.

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.

Bathroom Fitting- 7 Jun 2026
Excellent service and outstanding workmanship! I recently had my bathroom renovated by this company and I couldn't be happier with the results. From start to finish, they were absolutely professional in every way. The quality of their work is truly perfect - they paid such close attention to detail and did an amazing job with everything. What's more, the price they quoted me was very reasonable and they stuck to it without any hidden costs or surprises. The whole process was smooth, efficient and stress-free. I would highly recommend them to anyone looking for building services - they really are top class and provide excellent value for money. Thank you for such a fantastic job! To Abdullah and his team.

Conversions - General- 6 Apr 2010
After being let down by our previous builder, shortly before work was due to start, we were informed about this website, and somewhat hesitantly posted our garage conversion and kitchen renovation onto the site. After obtaining quotes from 3 builders, we decided to hire Nick cos of his straightforward and honest attitude to the job. We spoke with a couple of people that Nick had previously done work for, and they were very complimentary, so this just confirmed our decision to hire Nick. We have never undertaken any extensive building work before and were therefore nervous about the work starting, however I can honestly say that Nick was absolutely fantastic from start to finish of the project. Nick and his team were extremely hard working (finished much sooner than we expected), they kept the house as clean as possible when completing such works, and were generally an absolute pleasure to have around the house. Nick's craftmanship is exemplary and was always there to discuss any changes, extras or cut backs when not required. I would not hesitate in recommending Nick to anyone, safe in the knowledge that I know he would do an exceptional job, in fact more than three people have already asked for his details upon seeing the great job that he has completed here!! Thanks Nick for everything!!

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.

Bricklaying- 17 Jun 2022
Our brick garden wall was collapsing and I contacted Richard Fitzgerald for a quotation. I'd already had a few quotes from other builders, some of whom had told me I needed work doing that didn't need doing! I found Richard to be trustworthy. He provided a competitive quote. He managed to source bricks that matched the colour of the adjoining wall, gave us a detailed breakdown of the work he would do, and didn't ask for any payment in advance. He built a strong brick wall with a concrete support wall behind. The finished wall is excellent and we are very happy with the work he and his team have done. On finishing the work the premises were left clean and tidy. I am very happy to recommend him.

I asked Daniel to check and price some pebble dashing job. Daniel was fair in his pricing. He was on time in commencing the work as we had agreed. He never left the site until the job was completed within a few days, hence causing least interruptions. I do recommend him and I intend to ask him to carry out works in future.
