Kitchen Fitting- 20 Aug 2019
Jon is amazing, clearly highly skilled and his experience shone through, he did such a great job of fitting my kitchen. He was extremely patient with me and my kitchen supplier. He went out of his way to ensure I had what I needed to use my kitchen while we waited on other parts to be delivered. He also laid my laminate floor & perfectly hung 4 doors for me. There are one or two tiny bits pending, but to be fair he's waiting on me to decide when I want my other job done, so I know he will sort them out at the same time. I'd never use any other carpenter again. Jon is simply the best.

No job was too much trouble and they went above and beyond and did little jobs that cropped up along the way too. I would have no hesitation in calling Joe and his team in the future. Thank you.

Extensions- 15 Dec 2024
Fantastic company!!! From start to finish, Philip and his team have been friendly, polite and are clearly very experienced experts at what they do. Excellent industry knowledge enabled them to navigate some unforeseen complications with minimal fuss and cost. Finding a builder can be a very stressful process, as there’s a lot of choice and it’s probably the second biggest investment you’ll make, only second to the actual house itself. They’ve been absolutely brilliant, with almost daily updates on their progress and plans for what they’re going to do next. Made us feel very confident in allowing them to do what they do best without a single worry. Another thing to mention is the sheer speed at which these guys get the job done. Philip makes sure that he throws as many skilled men as he can at each stage of the build to ensure that it’s competed without delay. Does pouring the foundations on the second day on site sound like a great achievement?? It certainly does to me! Would recommend to anyone. Pick these guys, you’ll be glad that you did!

Kitchen Fitting- 2 Nov 2025
I can’t recommend James from Munday Interiors highly enough! From start to finish, the entire experience was faultless. James came to assess my kitchen and immediately stood out for his professionalism and expertise. He took the time to talk through what was actually needed — offering honest advice and practical recommendations from a non-expert’s point of view, which really helped me feel confident in my decisions. While I was away on holiday, James and his team completely transformed the space, and I came home to an incredible new kitchen. Every detail was finished to perfection — the quality of the workmanship, the precision in the fitting, and the overall care taken throughout the job were second to none. James was meticulous, organised, and genuinely passionate about delivering a high-quality result. The transformation speaks for itself — it’s modern, functional, and beautifully done. If you’re considering any kind of kitchen renovation or refit, don’t hesitate!

Conversions - General- 22 May 2026
Dan and his team were fantastic from start to finish! My wife & I were nervous going into the process of renovating our kitchen, but as soon as we met Dan we were immediately put at ease. He was flexible, positive, and reassuring, easily being able to work to our budget and realistic with time frames, and finished right on schedule! Above all else, Dan is an excellent communicator. I had some of the easiest, most straightforward exchanges with Dan that I've ever had when working with a professional. He would give regular updates on progress, and would be immediately transparent about any problems, setbacks, or surprises that came up along the way (as is the nature of renovation an old property such as this). All of the team were very respectful of our home and worked very hard the whole time they were there, big thanks to Greg, John, Aidan, Jamie, and Adam for their professionalism. They always had a great attitude and were a positive presence, and Greg's singing was a highlight!

What experience do you have with similar extensions in Caerphilly?
