Box Sash Windows are a traditional window style that became popular in the Georgian and Victorian periods, and can add style and a classic look to any home.
We work with high quality timber, and all windows are painted with low-maintenance coatings designed to withstand the elements.
All our sash windows are available with single- or double-glazed glass, and come in a range of styles to suit any home. Our double-glazing prevents draughts and significantly reduces heat loss, keeping your home warm and your energy bills down.
TM Sullivan have over 26 years’ experience in the trade, and over the years have built up a large portfolio of successful work. Please view our gallery for some examples of our carpentry work.
