I have no hesitation in recommending David and the team and CJK builders, from day one it was clear that they cared about our project as much as we did. The quality of the work was top class and the communication throughout the project was great too. We will be using them again for any further building work.

Top notch builder! The process:
I decided to extend the front of my house to increase my living area.
CJK Builders came highly recommended by a friend of my sister. I received a very detailed quote and decided to go ahead with the work. Building work was completely contained on my property and the impact on neighbours was minimised. A lot of effort and attention went into the groundworks, structural alterations and brickwork - the building inspector made positive comments and noted that David, the boss, dealt with issues that other builders would apparently have just left (there was a steel

Excellent team! After getting a number of quotes I decided to go with cjk for my large Extension project to my home in Wylam, and probably this was of my best decisions of my life! I have seen other builders struggling at a slow pace and poor quality workmanship in the area.
David Bain is a skilled project manager who scoped the job well and the project was completed ahead of time and within budget. His knowledge of the building trade is good and he is very approachable. The high quality work in all aspects of building work is plain to see, including the stone work. I thoroughly recommend CJK

When we were re-locating salon premises there was a lot of work to be done to get it up to a high standard. We asked around for reputable builders to quote for work to be done and offer solutions for a very challenging job. We found CJK very professional and they gave me options to overcome this challenge and gave me a very reasonable quote. They got the contract and the workmanship is outstanding.
