Customer Testimonials

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.

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.

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.

Over a period of 4 years Andy has installed several windows including a large bay and both my back and front doors. It has always been an excellent service both in quality of goods and installation. The making good around the windows and general tidiness after the work has been completed is also highly recommended.

From Our Website

A high quality home extension won't just provide an extended living area; it will transform the entire layout of your home. Home extensions add value to your home and provide comfort by raising living standards. If you're concerned about planning permission complications, you're in safe hands. At Andy Glass Windows, we will liaise with the local council's planning department and complete all necessary paper work on your behalf. We will draw up and submit designs and applications, so your home extension will be truly hassle free.

Composite Garden Buildings are suitable for a wide range of uses. The luxurious space can be utilised as your home office or a gym, or alternatively as a place to relax, unwind and get away from it all. Designed as a self-contained building to use all year round. The innovative construction utilises purpose designed modular composite wall construction with a core of high performance insulation to keep the space warm and energy efficient, with a warm weatherproof roof for year-round protection from the elements.

In addition to our high quality uPVC window range, we are also able to supply and install aluminium windows for customers looking for extremely durable windows in an attractive, energy efficient package. Aluminium has more recently become a popular choice for homeowners because of its low maintenance, durability and strength. Because of its strength, aluminium can also offer you slimmer sightlines than uPVC windows, which gives you great aesthetics whilst not compromising on thermal efficiency.
