Had work carried out by RS construction recently, was an overall pleasant and stress-free experience, had a dormant chimney breast removed all the way through my property. Which had to be removed due to constant leaks and repairs by previous roofers. Ross was very helpful and knowledgeable throughout the project and his team kept my house and garden very clean considering the work that was undertaken, it has not only freed space within my property but given me peace of mind concerning continuous leaks, which have caused numerous issues over the years. Can't recommend this company anymore , from sale to completion a very professional and helpful service
