JW Building Services - Open reference.

We employed Jamie (JW Building Services) to carry out an extensive two storey extension and internal re-fit of plumbing and wiring in the rest of the house in 2018. I’m happy to recommend Jamie based on the quality of his work, his personal yet professional style and also the diligence and commitment he put into the project.

All the work was carried out to at least and if not beyond the quality we expected, to the time and budget and also Jamie was very accommodating in dealing with the odd change and alteration to the plan as the project went along. Jamie worked with us throughout the build, he provided great advice when needed and also total clarity on any changes to cost as we asked for small changes / additions / alterations. So, in short, if you want a great job done by someone who cares, is passionate about delivering a great result and is nice to work with.....them I couldn’t recommend Jamie highly enough. I’d be happy to provide personal references if required and also show you his work at our house.
