Heritage style in the modern world

Sash windows are a precious part of our built heritage that makes the places we work and live special. Most people find them attractive.

But keeping them is not just a matter of taste. It also makes economic and ecological sense to keep them. Original timber windows were made of very high quality wood seldom found nowadays. It is a waste to replace them unnecessarily. Plastic windows consume a lot of energy in their production and most are only expected to last for around 20 years. When broken, most go to land-fills.

Besides, sash windows are a unique feature of your property. It gives it character and special appeal. 82% of estate agents we surveyed this year felt that original features such as sash windows tend to add financial value to properties and 78% believed they helped a property to sell more quickly. 

The common objection to original sash windows is that they are not energy efficient and there are very limited ways of upgrading them. But the effective repair or re-construction by Conservation Joinery Ltd can bring a sash window up to modern standards.
