Customer testimonials

The company provided excellent workers to complete a roof terrace refurb and even though the weather was against them (rain for the full month) they did a wonderful job. I wouldn't hesitate in recommending this company and their team. - Diana Gold

"Jewel made a number of suggestions as to how my apartment could be reconfigured to make it more suitable, including converting the kitchen and lounge to open plan and refitting a new kitchen and flooring throughout. The result was excellent! Also, the unusable garden was transformed into an "oasis" with paved and lawned areas almost doubling its size, and attractive running water features and lighting. The work was set out in detailed quotes and these were not exceeded. The work was carried out tidily and in a timely way. Jewel was subsequently awarded additional work in the apartment block by the managing agent." - H Karlcut

Please can we highly recommend Nigel and Les from Jewel Group. They have carried out multiple projects for us, including a fairly tricky barn restoration and conversion. They were always highly professional, timely and responsive, and we continue to use them on current projects. We would be very pleased to recommend their services. - Robert
