Pat was a pleasure to deal with from beginning to end he had everything covered and made the whole project a seamless experience. He provided me with a professional quote and had the patience to deal with my questions. He started the project on time svd no thing was too much trouble, when I needed a roofer to fix some issues with a leak he had someone on the job within a day. He handled every aspect of my garage conversion effortlessly and had the job finished on time right before Xmas. Would 100% use Pat again. Great guy who also knows good trades people. Thanks Pat.

Daniel quoted comprehensively and clearly for both jobs that I needed, building an extension and a raised patio at the end of the garden. He worked extremely hard and diligently every day. Also he would summarise what he would do next and we discussed any changes etc and which tiles or render I preferred. I am very happy with both the patio and extension and Daniel finished everything off to an excellent standard and went above and beyond the quote. I would not hesitate to use him again and recommend him highly.

Conversions - General- 25 Jun 2016
We've hired RFK builders without any reference but no regret on it. They are one of the best builders we've ever worked with. Excellent work, fast, reliable and good customer service. I found Bob and team are very friendly and helpful. They've quoted for the job very competitively and was clear about their availability to start the work. The job was completed really fast and they were flexible on accepting any changes I've proposed during the work. They've answered all the questions and always keen to explain why something has been done. They know their trade very well and always very quick to correct any issues. The quality of the work looks good and hope the time will prove the same. All the team members are very skilled, hard working and goes to extra mile to make it right. From my experience I am happy to recommend Bob and team for any building jobs. I've already hired them for the second job (new kitchen) which is almost finished.
