House extensions

White uPVC conservatory

Complete design & build service for home extensions in Oxfordshire

Opting for a high performance home extension from Andy Glass Windows means you get a fully invested installation service that sees it carried out by us directly, from start to finish. Whereas some other home improvement installers may contract out other work aspects when homeowners opt for a new conservatory or orangery, we complete all the work using in-house staff to give you a more professional and friendly service.

Our extensive range of house extension options already come bespoke and tailor made to your specific liking, however a high standard of quality is further assured thanks to the fact that we construct your new living space from the base upwards ourselves. What’s more, as a FENSA registered company Andy Glass Windows can install your new extension without you needing to register it with the local authority yourself. We’ll handle all of the leg work!

High performance uPVC and aluminium extensions adding value and space

Brick, stone, timber or otherwise, we can lay the perfect foundation to your new extension to always ensure the space is sufficiently sealed to retain heat and stable also. Whether your extension’s frame is constructed using aluminium or uPVC, your new conservatory or orangery will operate at peak energy efficiency thanks to double glazing techniques which easily achieves ‘U’ values of 1.0.

Not only is opting for a new glazed extension a futureproof and sound investment that will add financial value to your property, but it also provides a space in which you can use to fully embrace the outside without ever leaving the comfort of your home.

A range of windows and doors that provide the perfect finishing touch

You can choose the windows and doors you want for your new extension, from our full product range. From French doors that gracefully open up your home to the outside to tilt and turn windows that provide varying levels of ventilation, there’s no limit on the number of ways you can customise your new extension from Andy Glass all thanks to our complete design and build service.

Merry Christmas

"Prices were excellent..."

D Keegan, Oxford

After speaking with many traders, we went with Andy Glass Windows because they didn't try to give us the hard sell and because their prices were excellent. When they came to install, the 2 men were really careful, clean and very nice.

Merry Christmas

"Very professional..."

S Moss, Witney

From start to finish Andy Glass Windows were very professional, knowledgeable and there was no pressure selling. The surveyor was very thorough. The installers were prompt, polite, and did a very professional job installing our composite doors.

Merry Christmas

"Result is excellent..."

B Kirk, Cumnor

We were looking for a window product to compliment the renovation of our new home and Andy Glass Windows understood exactly what we were looking for and provided the solution with timber effect flush fitting windows. The process from ordering through to completion was very smooth and the finished result is excellent.
