Why choose Seal-Lite to provide your windows and doors?

We recycle your old windows and doors

window recylingRecycling

At Seal-Lite we don’t see recycling as just another buzzword or box-ticking exercise but as a commitment to improving the environment that we all have a stake in.

Household waste recycling is on the increase in the UK and traditionally glass, paper, aluminium, textiles and green waste were included and double glazing PVCu doors and windows were reserved for landfill.

With Seal-Lite you can recycle your old PVCu windows and doors so they end up becoming a new generation of products rather than being buried deep in the ground.

Double glazing PVCu house windows and doors have an average lifespan of 35 years and can go through the recycling process more than ten times before they lose performance capabilities – meaning that PVCu is one of the most sustainable materials in the house-building industry! So recycle your double glazing house windows and doors with Seal-Lite.


Experienced to help you choose the perfect products

help advisor who can offer advise on your productsOur experience

Based in Clevedon in the South West of England since 1987 we were originally manufacturing and installing just aluminium windows and doors. However, as consumer attitudes changed we began to manufacture and install PVCu house windows, doors, conservatories and garage windows.

Manufacturing and installing windows and doors in Clevedon, Weston-super-Mare, Nailsea, Portishead and Bristol for over 20 years means we have plenty of experience in delivering high quality home improvements.

We currently employ a loyal group of 30 staff and turnover is low. This means we understand the world of windows, doors and conservatories inside out and have the knowledge to offer a comprehensive and professional service, whether you are in the trade or a homeowner.
