Extensions- 18 Nov 2020
Unfortunately, Stuart Helm did not even start the job let alone complete it! Each time Stuart Helm was supposed to start work on the porch, he contacted me with an excuse explaining why he couldn’t start the work. This occurred over several weeks and eventually, we mutually agreed he would not be doing the work and I would repost the job. Very disappointing and lots of time wasted.

Extensions- 13 May 2026
Agim completed a ground floor extension for me in 2025 and I would not hesitate to recommend him for similar work. The quality of the work was excellent and the team worked tirelessly for months to ensure it was completed on time and for a reasonable price. Agim was able to adapt quickly when any unforeseen problems occurred, always clearly communicating possible solutions to help keep the project moving. Having people in your home can be difficult but Agim is very respectful and considerate, making sure to put our needs first. The results are fantastic and Agim continues to help snag any minor issues that come up. I couldn’t be happier with how things went, testament to his professionalism. Thanks Agim for all your help on this project.

Conversions - General- 21 Jun 2025
Working with Petrit was a very pleasant and enjoyable experience. He and his team are friendly and open for discussions. They’re quick, affordable, and help with decision making. Would hire again! Have to say as well, as a woman, Petrit and his team treated my husband and I equally, unlike my experience with other tradesmen who direct all their conversations to the men. Petrit knocked opened up our living kitchen area, laid herringbone floors, replastered the property, installed new radiators, added a built in ladder to our attic, and re did our bathroom. He also helped us match the floor boards from an existing room and helped us source front and back doors for much better price than what we were getting quoted in East London. The painting of the entire house was done in a rush as we needed to move in, so the attention to detail fell down a little here compared to everything else that was done, but I wouldn’t hesitate to work with Petrit again!! After and before pics included!
