About Us

How we got started, who we are and why you should trust us to restore your sash windows.

Through our national network of craftsmen we have established ourselves as the market leader in timber sash window and casement renovation & repair, offering a guaranteed and unique service.

Traditional timber sash windows are an essential feature of a period building’s character. It is therefore vital to retain them; not only because of the aesthetic appeal, but also because sash windows make your property much more valuable financially.

Maintaining the traditional features of your timber sash windows used to mean compromising on comfort. But not with Ventrolla! Our unique sash window renovation and performance upgrade service makes problems associated with old sash windows, such as draughts, rattles, rot and operational issues, a thing of the past, allowing you to enjoy your traditional wooden sash windows, regardless of the weather outside, and reduce your energy costs at the same time!

Renovating your timber sash or casement windows requires considerably less money and resources than replacing them with new ones. This minimises your costs and the harmful impact on the environment, making the process of your sash windows’ restoration mutually beneficial for everyone involved.
