    Period Property Restoration

    Posted 21 May

    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.

    An Innovative Design Solution Realised by a Skilful Team

    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.

    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.

    General Building

    Removal of wall to open up kitchen / dining room

    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.

    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!

    Excellent work

    Brilliant to work with. Not only did they carry out the work needed, but also made some great suggestions we hadn't thought of and ended up going with. Good price, punctual with great communication, and the invoice matched the estimate despite discovering some "surprises left by the previous builders. Will definitely be using again for the next round of work.
