  Bathroom renovation and refurbishment following water damage (BR4) KN Renovations were outstanding from start to finish! They responded swiftly with an emergency fix, provided a clear and fair quotation, and patient whilst I dealt with insurers. The team’s knowledge and efficiency meant the work was completed ahead of schedule, with daily updates that kept me reassured. Their professionalism, attention to detail, and customer care were second to none. I couldn’t have asked for a better experience and will 100% be using them again. Highly recommended—thank you, guys!
