From the stylish symmetry of Georgian Sash Windows townhouses to the elaborate detailing of Victorian vacation homes and Edwardian terraces, sash windows are the crowning jewels of these historic structures. However, time, weather condition, and disregard can take a toll on these fragile timber systems.

Unlike modern-day casement windows, they operate on a system of weights and sheaves. Over years, layers of paint, fraying cables, and timber decay can render them inefficient.
A professional refurbishment company focuses on "repair over replacement." This philosophy makes sure that the initial character of a residential or commercial property is maintained-- an element that is often a legal requirement for Grade I and Grade II noted buildings or properties within designated preservation locations.
