Client feedback

What our clients say

“Rhys completed the first side extension (shower room, coat cupboard, office, sun room) on our home in 2020 and provided us with what is now our favourite room in the house. We had some issues with the flooring which were resolved, and Rhys accommodated the many changes I made along the way. One of the biggest things for me was the trust. I was happy for Rhys and his team to be in my home, and more importantly, around my children. They are honest, hard working and reliable. So much so that we are almost at the end of our second job with them - a loft extension providing 2 bedrooms and a shower room. I didn't even get another quote as I knew I wanted them back - the level of aftercare they provide and just general helpfulness is worth every penny. Plus my kids love them :) Rhys has kept me informed every step of the way, and has provided the advice I have needed when I couldn't make decisions. I thoroughly recommend Rhys, Keenan and the team and will use them for anything else I need in the future.”

“Fantastic service from start to finish. Professional, reliable, and the workmanship is top quality. The team kept everything on time, on budget, and went the extra mile. Highly recommend Rhys and his team!”

Megan Burrows · Google review

“From the moment we met Rhys in 2022, he and his team have been nothing but amicable, reliable, and incredibly trustworthy. We undertook a loft conversion and a double-storey rear extension over two levels—no small feat! As with any major building project, there were naturally moments of uncertainty and times when things didn't go exactly to plan, but Rhys was absolutely incredible throughout. He offered practical advice, brainstormed cost-effective solutions with me, and always maintained clear, open communication. Together, we found creative ways to tackle challenges and keep the project moving forward. You can truly tell that Rhys loves what he does—he consistently goes above and beyond. We absolutely love our new home and are extremely grateful to Rhys and the entire team. Over the past few years, we've built a great working relationship, and I would wholeheartedly recommend Rhys Child in a heartbeat to anyone considering changes to their home—big or small!”
