Windows, Doors & Conservatories
Birmingham, Evesham, Knowle, Stratford upon avon, Solihull, Bromsgrove & Henley in Arden

We believe that in order for us to provide you with the best solution for the project that you are interested in, we need to firstly fully understand how the product will be used.

Here at Mainstream, we operate on a clear and proven ethical approach, and we do not operate a ‘door knocking’ policy. It’s not about selling you a product – it’s about providing you with the correct product for the job, and to assist you in getting the best value for money for your home improvement. It’s all about understanding your lifestyle really – for example, where to place the doors on a conservatory will be completely different if you have children, due to entrance and exit options. The same goes for the height of opening on the window above the kitchen sink – you will be surprised how often this is overlooked!

Mainstream is a specialist manufacturer of high quality Windows, Doors & Conservatories operating in Birmingham, Bromsgrove, Solihull, Evesham, Knowle, Stratford upon Avon, henley in arden and all surrounding areas. We have a huge range of products including conservatories, bifold doors, orangeries, school windows, glass extensions, pvc and upvc windows.

Treating You like An Individual

No job is too small or too large – and you will always be treated as an individual client, and not a reference number even, when dealing with us online, and you will remain in control at all times. And if you are looking for something different or bespoke, we can even make one-off products, to enable you to have something that no one else has.
