Longstanding customers

We have long standing relationships with our residential and commercial customers and partners.  We are proud to have received great feedback from a number of repeat customers who know they can expect high-quality products and great customer service from the team at Clement Windows.


The best on the market’ from Tom Robbins – Google reviews – 5 stars

“Clement supplied the steel windows with leaded lights set into oak subframes for an Arts and Craft house we worked on in Weetwood, Leeds.  We built an orangery there, as well as the garage and kitchen conversion.  Clement replaced the windows throughout the existing house as well as supplied the new fanlights for the orangery.

We also specify Clement’s conservation rooflights whenever we can.  We are very much of the opinion that they are the best on the market.”
