Would highly recommend Gavin and his team. We were recommended this team and waited 18 months for work to commence. We can now understand why! Throughout the build at every stage we were kept informed. Alternatives were offered and many excepted. Time away from site was minimal normally waiting building material special to site. All the team where polite when I butted my nose in and a pleasure to have around. We are now fully enjoying their hard work and we have no hesitate in recommending the company to all. Thanks Gav and the team.! - Pete & Anne

We would like to take this opportunity to express our appreciation for the excellent work you carried out, building our extension, porch and drive. We have been more than delighted with the quality of the work and the reliability of your team. You have done an excellent job, completing the build on budget and on time, even with all the extra work added. On site, your team worked extremely hard; they arrived first thing every morning, worked hard all day and cleared up at the end. We were impressed with the thoroughness of their work- they did an excellent job. Inevitably, with every build project, a few unforeseen issues and changes arose, and these were dealt with promptly and professionally. We really appreciated the good advice you gave us on some of the decisions we needed to make, before and during the build. We would happy recommend you and your to team as a reliable, professional and competitive building firm. - Steve and Julie
