Our Testimonials
We have used Ian on many occasions now to help us with below ground solutions. From the design stages through to the installation Ian and his team have done a great job. Do not hesitate to contact Ian if you are after a new installation or have an existing issue with damp.
Ian and his team were a hard-working, experienced, friendly bunch. They always turned up on time, worked hard and left the site cleaned up at the end of the day. Ian worked hard to ensure that the build kept within our timescales and amazingly pretty much within budget. Our experience went very smoothly with no major issues, but if we had any issues or questions Ian was always on hand to offer his advice and come up with a solution. Ian even helped us to set up a temporary kitchen for use while the build was taking place (complete with old sink and running water!). We’re really pleased with our finished extension and would definitely recommend Ian as a reliable, competitive builder.
Ian is hard working, efficient, reliable and a tidy worker. He has completed work for us on many occasions and we have never been disappointed. His work ethic is second to none and we would highly recommend him.
