Written by the company
For more than 35 years, Seal Lite has been helping homeowners across the South West create homes they feel proud of. Based in Clevedon, we’re an independent team known for friendly service, honest advice and high quality craftsmanship — values our customers consistently highlight in their reviews. We design, manufacture and install secure, energy efficient windows, doors and conservatories in uPVC, aluminium and composite materials. From traditional sash windows to sleek contemporary designs, every product is made to order with a wide choice of colours and finishes, so your home looks exactly the way you imagined. From the moment you get in touch, you’ll speak with a knowledgeable, no pressure advisor who listens to what you need and provides a clear, competitive quotation. When you choose Seal Lite, we take care of everything — from survey to manufacture to installation — using our own highly experienced, fully employed fitting teams. And if you ever need support afterwards, our dedicated After Sales and Service Team is always here to help. Our customers often mention how safe and well organised their installation felt. That’s because we invest heavily in training, equipment and independent safety audits, giving us an excellent safety record. We’re also committed to doing things the right way for the environment. Almost all old windows, doors and glass are fully recycled, and our 80kW solar array helps power our Clevedon site as we work towards net zero carbon emissions. Seal Lite has grown year after year thanks to the loyalty of our customers and the dedication of our long serving team. While our business continues to evolve, our promise remains the same

The company and fitters were very polite and answered all our queries. On the day of fitting they arrived on time, were clean and efficient and did an excellent job taking away rubbish and tithing up.

Absolutely excellent!
We are no strangers to Seal-Lite who replaced a good many of our windows. They were therefore our first choice for upgrading our conservatory to a more liveable space. We are delighted with the result. The installers were professional, diligent and very hardworking. Any little problems were dealt with immediately. We have nothing but praise for them and would highly recommend.
