Novaseal has two decades of experience in the double-glazing industry. We’ve grown mostly because of our reputation and are often the first choice for customers seeking affordable home improvement solutions in Southampton, Portsmouth, West Sussex, Chichester, the New Forest and the surrounding Hampshire areas. Novaseal is a supplier and manufacturer of uPVC and aluminium products. From market-leading windows, doors and conservatories, through to cladding, and roofline, we can act as a one-stop shop for commercial or residential customers looking for affordable solutions for a project – whatever its scale. We invest in our teams and our products so that we can continue to deliver the best products and service to our customers. 70% of our machinery is brand-new, and we’re proud of the fact that, on average, people stay with us for at least nine years. This means that we have the capacity and experience to respond to almost any project. You can explore – and get prices for – most our double-glazing products using our design tool. We also have a dedicated trade counter, so that our customers can talk to us in person before making a purchase. Our stock levels are always high, so you’ll be able to find what you need.
