A wonderful service from start to finish. Simon recommended a high quality product and even advised us when the door we were after was on a special promotion. The lead time from ordering to delivery and fitting was four weeks compared with other companies offering two – three months. Installation was fantastic, with the team arriving at the time advised, clearing and tidying up before they left. Our overall experience – five star, we would highly recommend!
