The bright side of choosing aluminium-glazed windows is that they naturally resist corrosion, rot and rust. Virtually, they are maintenance-free yet demand a little care to last a long time. Exterior Plas offers you this advantage and a comprehensive repair service to deal with woodworms, condensation and everything in between to keep properties in optimum condition. We know a lot of work is involved, like regular treatments, for you to enjoy thermal efficiency, durability and other benefits. As experts, we take care of every aspect. This is exactly what sets us apart.


We recommend cleaning the glass once a month and the frames every two months to prolong the life of the fenestrations. Call us if you need a professional service from an aluminium window manufacturer in London to retain the appearance and integrity of the material.

Low Maintenance

Due to their durability, aluminium windows are easy to maintain. Depending on the finish, a clean of the frames and glass once every two to four months is all it takes to keep them sparkling.

Long Lasting

Aluminium windows are extremely durable thanks to their high strength to weight ratio. This means that they are hard to dent and are also resistant to weather conditions. As a result, they are less likely to rot, corrode, flex, or warp and can last for up to 30 years.

Energy Saving

New technological developments (e.g. polyamide technology) has helped make these windows an energy-efficient choice by helping insulate heat and minimise heat loss. As a result, it can have a positive impact on energy bills.

Environmentally Better

We know that making an eco-friendly choice is important to our customers. Aluminium is 100% recyclable, fully sustainable, and non-toxic. This means it leaves an eco-friendly footprint.
