Zak did a fantastic job of setting up our data cabinet in the office. All work has been done to a high standard and Zak and his apprentice were very tidy. We now have a fully wired gigabit LAN with ports in each room and wireless access points across the house. Highly recommended. P.S: Zak can punchdown cat6 using his muscle memory without the need to look at the patch panel whilst having a full conversation :)

Dan(boss) and John completed my work ahead of schedule. My wife and I were extremely pleased with the quality of work completed by them. Dan and John worked extremely well as a team and their interaction with the customer was excellent. Also, their professionalism and commitment to do a good job was evident and nice to see. At the end of the job, they left the work site very clean and tidy. Absolutely no complaints - and I would have no hesitation in recommending them to others.

Bricklaying- 19 Apr 2019
Excellent - Very impressed with the work and their attitude, nothing was too much trouble for Ben and his colleague Josh. Turned up when they said they would, completed the job on time and did a great job. They coped with minor alterations I made, and came to me with solutions to any issues they encountered rather than just presenting me with the problem. I will be using them again for future work and would highly recommend them. Nick

Graham replaced the windows at the front of my property. Four windows in total. The quality of work was superb with a close attention to the finishing off. The work area was kept very clean at all times. The job from start to Finnish was excellent. Completed on time and at the price quoted. Graham’s strengths were everything I would of expected from a trades man. Turned up on time from start to Finnish. Kept me informed of the process till the end. Was a very friendly chap. And I have already recommended him to 2 other friends for work of which he as all ready completed installation of 1 job.

Extensions- 12 May 2023
Rowan was one of the first to respond when I posted my job so we arranged a visit . He is a very pleasant , likeable person . He talked us through the process and explained what would happen at every stage of the project . Although Rowan doesn't live close to us , he made himself available for support and guidance from the start and I knew I could call him with any questions or concerns I had and I did this a few times . Rowan has been in the industry for many years so not only has extensive experience , but he has extensive knowledge of the trade , materials , products and building regulations . Importantly , Rowan is very honest and transparent about the cost of individual products as well as the actual build and if he isn't able to answer a question , he will not give false information but he will again , be honest and tell you he will do his best to find out and get back to you . Ultimately , I would not hesitate to recommend Rowan if you are looking to engage the services of a very professional , experienced and knowledgeable builder who takes pride in his work and will complete your build to an extremely high standard .
