Ahmad and the Beam Developers team did an amazing job on my rear extension. We were very particular with our requests and are generally picky people but they were very patient and accommodating to our every request. We were shown the drawings, made adjustments and managed to tailor the project exactly to what we wanted. The finished results were amazing. No big project for us soon but should we plan to do the loft will definitely use Ahmad and his team again.

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.

Carpentry- 10 Aug 2023
you will see I ask for experts in my job posting because my desired outcome of this job was quiet floor as you walk across. I hired LTDinchev and the 2 gentlemen were helpful, pleasant and friendly. The job was completed for the price quoted and in the time specified. my only disappointment is after the job was completed I still had SOME of the same floor noises. so although they work hard on my subfloor I did not get 100% my desired outcome.
