Plastering- 4 Oct 2026
Extremely disappointing experience – poor workmanship and lack of professionalism. Please be careful before hiring this tradesperson. I hired him to carry out plasterboard and plastering/skimming work, with an agreed price of £3,000. I paid £1,500 upfront, but unfortunately the work was left in a very poor and unacceptable condition with almost 10 days delay. The workmanship is far below what I would expect from someone presenting themselves as an experienced professional. There are significant problems including uneven surfaces, poor corners and joints, gaps, unfinished areas and poor attention to the details. Unbelievable how these guys can be in the market? In my experience, the quality of the work does not demonstrate the level of skill or experience anyone can expect from a professional plasterer. I am now must to pay another professional to inspect and rectify the horrible work, I hope my builder would help me! I would strongly recommend other customers to avoid this person.

What experience do you have with similar extensions in Cricklewood?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Cricklewood extension builder’s ability to deliver a result that meets your expectations.
