Why choose us?

We needed a complete plumbing and heating overhaul to a large property with very old, confusing and complicated plumbing that needed to be updated with 2 new boilers, 25+ radiators and then split into multiple zones. We took a risk with Jason based on the very good reviews we had read and are absolutely thrilled with what he has achieved in just over 2 weeks. By applying a calm and methodical approach to problem solving, Jason works hard to provide a professional finish and the right solution. He is very punctual, excellent at estimating his effort and reliable. We particularly appreciated Jason’s prompt response to our emailed question throughout the process. We will be very happy to have Jason come back for more projects. Thank you Jason.
