About Mainstream Windows Birmingham

For over 20 years, our award-winning FENSA* regulated firm has successfully manufactured and supplied windows, doors and conservatories to our clients. Our company is owned and run by three experienced directors that work in a ‘hands-on’ role – and actually know how our processes work!

We pride ourselves on attention to detail, and all of our products are manufactured ‘in-house’ at our Head Office in the West Midlands. And the same goes for our fitters – they are our own trusted staff, with many years experience between them.

In order for us to supply you with the best energy rated product, we prefer to fully understand how you are going to use the product – before we make any suggestions.

Call us old fashioned – but our history and experience confirms that by supplying you with the product that best suits your needs, rather just making a sale, will give you years of enjoyment and satisfaction, rather than heartache and frustration. Our friendly ‘family’ firm are just an email or telephone call away – please contact us to discuss your requirements.

* FENSA stands for the Fenestration Self-Assessment Scheme. It has been set up by the Glass and Glazing Federation (GGF) and other industry bodies with Government encouragement in response to the current Building Regulations for England and Wales. When having windows and doors replaced homeowners must comply with current thermal performance standards and ensure that they get a certificate of compliance from FENSA or from Local Authority Building Control. FENSA also enables companies that install replacement windows and doors to self certify compliance under these Building Regulations.
