Alpha Windows are a family partnership established in 1976. We pride ourselves on offering both a professional service and competitively priced products.

Our intention is to remain a family business, very much ‘hands on’ where everyone in our company knows our customers personally. We will listen carefully to your requirements and endeavour to provide you with the best possible service from sales through to installation.

Your home is likely to be the most expensive investment in your life. The appearance of your home can be greatly enhanced or destroyed by poor design and installation. You can trust us to give you both quality in design and installation.

Alpha Windows are a Fensa (Government initiated body to police the double glazing industry) registered company and all applicable installations will be certificated.

Our showroom is conveniently located with parking. We have various window designs, doors and a conservatory on display and would welcome a visit at any time to discuss matters further with us..

Why choose us?

We are proud to be a family firm that cares. More than 60% of our business comes from recommendations. We cover, not just, the whole of Berkshire, but also Oxfordshire, Hampshire and Surrey. We are known for the quality of our workmanship as well as our first class customer service. You can view our many satisfied customer comments on checkatrade.

Our guarantee

All products and workmanship are covered under our normal terms and conditions. Alpha Windows also provide a Deposit Indemnity Certificate together with a 10 year Insurance Backed Guarantee free of charge issued direct from QNAW.

Some of our recent projects…



During COVID-19 Lockdown

Due to a series of strict measures introduced by the government to help fight the Coronavirus outbreak Alpha Windows showroom is temporarily closed to our customers. We will be re-opening on an appointment only basis as of Saturday 23rd May 2020. However, please keep a close eye on our website and / or Facebook page as this is subject to change.

We would like to reassure those that already have a contract in place with us and are awaiting an installation, that we are working through these to be arranged and completed as the restrictions are gradually lifted by the government.

As always, we are continuing to process any quotes & orders, so please do not hesitate to call us on 0118 3766 800 or email and we will get back to you as soon as we can. If you are able to provide us with any measurements or photos of your property with your enquiry that would be much appreciated, however this is not essential and we may be able to send a member of the team without coming into your home. (Please note that this is dependent upon the enquiry)

In the meantime we hope you are all staying safe and wish you all the best during this time.
