Glass Extensions Carshalton

A modern glass extension is the ideal way to expand the living area in your Carshalton home. You and your family can enjoy a functional home, with more space to play, relax and enjoy family life.  Benefit from a long-lasting, weatherproof home renovation from Castle today! 

In order to increase the amount of light that enters your property, we employ large glass panes in the design of all of our glass extensions. The additional light will provide a gorgeous retreat for you and your family to enjoy, along with lovely, expansive views of your garden. Double glazing also keeps you comfortable regardless of the weather outside due to its remarkable thermal capabilities. Thanks to our glass extensions, you can now control the temperature inside your building regardless of the time of year.

Create a seamless link between your Carshalton home and garden, without the need for connecting doors. No matter your requirements, we can create a bespoke design for your property, thanks to the level of customisation options we provide. Turn your new space into a play area, games room or personal sanctuary. The options are endless! 


Thermal Efficiency

Modern double-glazing technology is at the forefront when it comes to our glass extensions. To increase heat retention, hot air is kept in a vacuum between the glass panes. Installing one of our insulating glass extensions will put an end to your worries about heat loss!

You may also benefit from reduced heating bills thanks to the industry-leading double glazing technology we employ as standard. By using less energy, you and your family can contribute to a greener world!

Increased Light

By adding one of our glass extensions, you can maximise the natural light in your home today. Large windows with double glazing will let in more light, creating a brighter home and giving the look of a larger interior.

We provide a variety of glass roof alternatives, allowing you to customise the final look of your new investment. There are also several glazing options, such as total glazing. We can even add a modern roof lantern that doesn’t sacrifice light quality to provide you and your family with a greater level of privacy!

Market-Leading Materials

Each of our glass extensions is built with the toughest, most energy-efficient materials. Every material we employ provides a variety of advantages due to the use of contemporary production methods. Since we make our items with quality and care, you can unwind knowing that your investment will last for many years to come.

No matter if your Carshalton property is modern or more traditional, our glass expansions are the ideal addition. With your brand new investment, your home will be the talk of the street!

Weather Resistance

Your Carshalton home will look and feel larger and more comfortable with any of our glass extensions. We construct our glass extensions using weather-resistant materials to prevent water and mould from entering your home. Additionally, the double glazing maintains a comfortable interior temperature and shields against draughts.

Your property might suffer structural damage from unpredictable weather. Even when exposed to the worst conditions, our glass extensions won’t shift, break, rot, or distort. Our durable products will enable you to relax in your new living space for many years to come.
