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.

I've used lots of different tradespeople through My Builder but this was the first time I went for someone with no reviews… and I needn't have worried! Luke was great from the off - he came to quote quickly, was really friendly, professional and was happy to give advice on the gate design. He built it in the agreed timescale and it looks brilliant! He'd even gone to the effort to stain it all so it matched our new fencing perfectly. There was one change we wanted to make to the design after delivery and he came back and sorted it straight away. The whole process was wonderfully smooth and we're very happy with the results. What's more, it was better value and a nicer gate than we could have bought off the shelf. Would definitely recommend or hire for further carpentry work.

Electrical- 14 Oct 2018
During the cutting phase of our ceilings, the insulation company had to stop the job and asked us to get the electric cables checked by a professional before they seal the foam. It was 6pm by the time I posted at MyBuilder and Rob was very responsive to help us understand whether there is a problem. He came and checked the cables the other day right on time, even talked with the insulation team himself to solve the technical issues. He was very proactive and full of advice and he tested all our electrical cabling system also the other day. We can not thank him and recommend him more. If you need urgent yet professional and friendly support Rob is the right contact. Thank you Rob!

We are very happy with the job he did and will have no hesitation in employing Paul in future projects.
