10 Bathroom restoration.
Posted 4 days ago
Joni provided honest, helpful advice and excellent communication throughout our home restoration project. The team sent regular video updates of the daily progress, which gave us great peace of mind. The workspace was kept incredibly tidy and clean throughout the week. Joni was highly flexible, accommodating, and very clear with all communication. Overall, the team did a fantastic job, stayed right on budget, and delivered high-quality workmanship. They kept the property clean and today every day. We have no hesitation in recommending Joni and intend to use him for all future projects.Verified reviewerJob location: OX310 Outstanding workmanship and reliability

Joni and his team have done three projects for us and each of them has been completed really well, on time, on budget and with genuine care for the property. Highly professional approach to the work with real attention to detail and finished to a very high standard. We can't praise him too much.Verified reviewerJob location: OX1- DDuncan T
9.33 An Innovative Design Solution Realised by a Skilful Team
Posted 14 April
Joni and his team had the task of converting an airing cupboard into an upstairs toilet and installing a new boiler in the loft space. The solution Joni designed to fulfil this tricky task was innovative, elegant and wholly successful. I was delighted by the finished product. Unfortunately, the project hit one or two hitches due to a somewhat unreliable plumber and the build took longer than expected. But everything else was impressive: the work was completed with skill, care and pride. Everyone on the team was polite, friendly and professional-- and the bill for the work was very fair.Verified reviewerJob location: OX3 10 Knowledgeable, professional, reliable building company

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.Verified reviewerJob location: OX1- BBruce W
10 Removal of wall to open up kitchen / dining room
Posted 11 December 2025
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.Verified reviewerJob location: OX5 10 Thrilled and highly recommend.

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!Verified reviewerJob location: OX1
