Electrical- 14 Oct 2018
During the cutting phase of our ceilings, the insulation company had to stop the job and asked us to get the electric cables checked by a professional before they seal the foam. It was 6pm by the time I posted at MyBuilder and Rob was very responsive to help us understand whether there is a problem. He came and checked the cables the other day right on time, even talked with the insulation team himself to solve the technical issues. He was very proactive and full of advice and he tested all our electrical cabling system also the other day. We can not thank him and recommend him more. If you need urgent yet professional and friendly support Rob is the right contact. Thank you Rob!

Ryann and his team first completed a multiple room ground floor extension for us, including the installation of a new kitchen and bathroom. We were so pleased with the work that we asked him to build an outdoor garden room from scratch and completely refurbish our other bathrooms. We have always found Ryann to be friendly, punctual, knowledgeable and honest and I am more than happy to give my recommendation.

Conversions - General- 13 Jan 2026
Dan and his team recently converted our garage to an office. Amongst other things this involved exposing the timber trusses, installing rooflights and plastering around the trusses and the soffit of the roof. The standard of workmanship was exceptional and the garage now looks like a totally different space. We are so happy with how it turned out. Dan and his team were always pleasant and respectful to be around, and we were able to have honest and open conversations throughout planning and the design & build, so that we could get to where we wanted to be. I would thoroughly recommend DJ Home Improvements, not only do they deliver a high standard of work, they are always listening to what you need and adapt accordingly.
