Bathroom Fitting- 9 Jan 2015
Aggi and Pedro were excellent. They helped me to decide what fixtures and fittings I needed (including also doing some research themselves) and when it came to fitting the new bathroom they did it to a high standard and were tidy/cleaned up after themselves. I would recommend them.

Carpentry- 13 Aug 2026
Alex did what I asked and did a great job installing the awning. He also installed a metal shed and put up a beam to cover part of a wall. Overall, the work was good, although a few small details were missed in the shed, which seemed to be due to a lack of attention to detail. I found the price a little expensive, but overall I’m happy

Handyman- 17 Aug 2026
Very please. Small but awkward job, painting an outside steel roof. Provided quote based on my description and photographs, offered to do the job promptly and completed the job while I was away. Kept me informed of the few difficulties and gave me options on the paint used. Completed within a day and kept the work area tidy. Would happily use again. (Before and after pictures attached)

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.

Plastering- 11 Apr 2026
Absolutely thrilled with the work carried out by Harman. The skimming has been completed to an exceptionally high standard - the finish is incredibly smooth and completely seamless. Harman and his colleague were professional throughout: tidy, courteous, and very polite. They took great care to properly protect and cover the surrounding areas, leaving everything clean and intact once the job was done. What really stood out is their attention to detail and commitment to getting everything perfect - even offering to return for any final finishing touches if needed. I honestly couldn’t recommend them highly enough. Brilliant job from start to finish.
