Why Choose Silverline?

Silverline Windows Ltd was established in 1981 by our father, Andreas Michael. He found a niche in the market by offering high quality bespoke windows and doors to the local community around North London. Since then, we’ve built an excellent track record supplying and installing aluminium and UPVC windows and doors.

Our enviable reputation and continued success are based upon honesty, reliability, integrity and outstanding customer care. The vast majority of our work comes from recommendations and customers who return. Our business has grown from windows and doors to a diversified portfolio of other products. These include bi-folding doors, shop fronts, conservatories, stained glass, kitchen and bathroom glass, architectural glass and more.

Silverline always uses the very latest technology in windows and doors systems. This ensures that our products are always of the highest standard.
