Update R.E. COVID-19

In response to government guidelines on COVID 19, that all non essential work should no longer be carried out, Castle Windows (Newbury) Ltd are temporarily ceasing the customer facing aspects of the business.

Our depot/office is now closed.  Our fitters will not attend new installations and future installations will be put on hold.  Our sales advisors will not visit customers but can instead give advice/quotes by phone or email. We may be able to help in an emergency situation (i.e broken lock) depending on if we have an engineer available.

As a local family business employing and using the services of a number of local people this will of course have an adverse effect on the livelihoods of our workforce.  However the health and well-being  of our staff and the communities in which we operate are of the utmost importance so we will not be operating as normal until permitted to do so and we thank our customers for their patience and understanding during this time.

We hope we can continue to rely on local support when we get back to normal so that we can come back stronger than ever.  This is our 30th year of trading and we have lots planned for the future including the opening of a new showroom!

Please do everything you can to ensure your well-being and the well-being of those around you.

I’ve been a customer of Castle Windows for around 20 years and have always had excellent service , I needed to claim on their warranty recently five years after the door was fitted and it was replaced quickly and efficiently with no quibbles at all.

Rich Fielding -

Great service from start to finish, aftercare brilliant too.

Helen Chalmers -

Brilliant job. Quality of service as well as the products were good. It did take a bit longer than i expected, but the end result more than makes up for it.
