Latest review:
We initially hired Michael to convert a bathroom into an office. After meeting him and discussing our longer-term plans, we quickly felt confident moving forward with him on much wider renovation works across the property. Michael worked closely with us throughout the entire process—from early ideas and structural planning through to execution. He consistently provided insightful, practical advice that added real value. His ability to anticipate issues early not only prevented problems but also helped us save money by refining the plans to maximise our goals and avoid unnecessary costs. Michael’s broad knowledge and skill set were hugely beneficial on a project of this size and within a tight budget. He made the process far less stressful and, at times, genuinely enjoyable. He kept me informed and involved at every stage, which gave me a great deal of confidence in both the quality of the work and the decisions being made throughout. Michael helped us renovate every corner of our four-bedroom maisonette in West London—from bathrooms and structural opening-up works to a full kitchen renovation, hard landscaping, flooring, and carpentry. The list goes on. His wide skill set and depth of knowledge were truly impressive and exactly what we needed, particularly as we chose to stay closely involved in the renovation rather than hiring a larger construction and project management company. We genuinely don’t feel we could have made a better choice. It’s not always easy to find a builder who is reliable, honest, and trustworthy, so I feel very fortunate to have worked with Michael. I would recommend him without hesitation and will absolutely continue to work with him on future projects, big or small.

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.
