Joni and his team completely redesigned and rebuilt our front basement and street level entry ways. They underpinned walls, dug down so we could have a full-height door, rebuilt two sets of steps, and repaved everything. They were organised, approachable, knowledgeable, tidy, and professional. We ended up asking Joni to consult on lots of other things while he was there as a result, from insulation to repointing to damp. We are the 6th house he’s worked on on our street because everyone keeps recommending him. His prices were very transparent and reasonable. He sorted out everything we needed.

Detailed reviews
Joni was fair and honest with the quote he gave us and stayed true to it. He gave advice on next steps in the planning process, which, as first time applicants for building control, was helpful and kind. He always arrived on time, whether that was to quote, pre-visit, or carry out work. He communicated well with us. He and his team were excellent during the week of the works. They kept the home clean and tidy as possible and kept us informed as the project developed. The end product has made a difference to our property and we are so happy we chose Joni and will use again in future.
VERY impressed with our experience with JBS. Jon and his team worked tirelessly (and with endless patience!) to bring our new side return, kitchen and bathroom dreams to life. Jon had a real attention to detail in his project management and building skill set. Honest, open and helpful communication throughout - we felt very much part of the process and included in all discussions. Felt very comfortable having the friendly, warm and approachable team in our house for several weeks. JBS came highly recommended from several neighbours and we’re thrilled with our new home!

This trade isn't licensed in the UK, so anyone can set up. TrustMark is the only Government-endorsed quality scheme for work in and around the home - check whether they're registered, or find a TrustMark-registered business.
Check the TrustMark registerNever pay a large deposit up front. Agree a staged payment schedule tied to completed milestones, and hold a small retention until snagging is done.
Get it in writing: an itemised quote with scope, materials, start and finish dates, and how any changes (variations) will be priced.
Be wary of a cash-only price or pressure to start tomorrow. Both are red flags for an unaccountable job.
