Highlights
"I couldn’t recommend this firm enough, from start to finish they went above and beyond. This time using them they’ve done all the drainage and blockwork for my 2 bed detached modern bungalow/lodge. From the beginning of the job Kris helped me with the ongoing work in other areas his knowledge on new builds is second to none. He didn’t come in the cheapest but learning from past mistakes pay cheap pay twice and end up with headaches along the way. This time round there has been no headaches all plain sailing. Great team and left the site spotless when they finished. Thanks lads"
"Kris and his guys did the ground work for our extension and they were absolutely brilliant. Ten out of ten!! The communication was excellent throughout. Very professional, honest and trustworthy. . They were always on time and all the guys are extremely hard working. All the guys are very experienced. Kris always kept us up to date on progress. They were also brilliant with the neighbours, very friendly and polite, going out of their way to make sure everyone was happy and considerate with parking. We would 100% recommend KJ’s to anyone considering using them."
"I’m delighted with my new garden area. The workers were first class on time keeping. Great communication. I was kept well informed and involved in decision making. The site was kept tidy and safe at all times. My safety was prioritised. Beautiful job."

Kris & his team have been an absolute pleasure to work with on our kitchen extension project over the last few months. They have been professional and friendly, with a great attention to detail. Kris approached the project and all of the challenges that we had with a great positivity and can-do attitude. We are absolutely delighted with the finished result and couldn’t have asked for a better team to help us get here. I wouldn’t hesitate recommend Kris and his team for future projects.

Before you hire a builder
Never pay a large deposit up front — agree a staged payment schedule tied to completed milestones, and hold a small retention until snagging is done.
Get it in writing: an itemised quote with scope, materials, start and finish dates, and how any changes (variations) will be priced.
Be wary of a cash-only price or pressure to start tomorrow — both are red flags for an unaccountable job.
Ask to see a portfolio of completed work like yours, plus recent references you can contact.
Check the credentials and registrations that matter for this work — and that they are current.
