Windsor is synonymous with royalty, history and prestige. Dominated by the Castle and set on the banks of the Thames, the town draws visitors from around the world, but it is also a thriving residential community with some of the most desirable addresses in Berkshire. The streets surrounding the Castle and along the river feature historic buildings within multiple conservation areas, where any alterations to windows and doors must be handled with sensitivity and knowledge. Beyond the town centre, Windsor’s residential areas stretch from the elegant Victorian and Edwardian properties in the streets around Clarence Road and Frances Road to the substantial family homes in Clewer Village and the modern developments near Dedworth. The proximity of Windsor Great Park adds an additional layer of prestige, with some of the finest private homes in the Royal Borough located along its fringes. Vitrum Solutions provides expert double glazing installations throughout Windsor, offering the premium products and meticulous attention to detail that this exceptional town demands.
