Sealasash provides a premium restoration service to make traditional wooden sash windows work properly and add high performance draught seals, which reduce energy costs and improve home comfort.

Why Sealasash?

The wooden sash window is a characteristic of many older houses and commercial buildings. Windows form an important part of our architectural heritage but many sash windows no longer work as they were intended to.

They have been painted, nailed and screwed shut over the years in an attempt to reduce annoying rattles and draughts. These nonfunctioning old windows can be made to work efficiently, slide effortlessly and be draught proofed without compromising their architectural value.

Old wooden sash windows do not need to be pulled out and replaced. Get them fixed and restored with Sealasash.
