RJM Windows

Rob and Julie McKane founded RJM in 1986, initially specializing in wooden doors and windows. Before long, it became clear to them that PVCu was the future. When the company moved to a much larger site 10 years ago, RJM began manufacturing their own high-quality products, allowing them to offer windows, doors and conservatories direct to their customers at excellent prices. In 2003, RJM acquired a brand new showroom, which enables visitors to see and touch the products before they buy. Customers can even relax with a tea or coffee in a number of fully-furnished sample conservatories on site, giving them a real taste of the quality that RJM offers. With an ever-expanding product range and a total commitment to exceptional service, RJM Windows is your first choice for home improvement.
We understand that the decision to improve your home is never taken lightly - which is why RJM offers a complete service at every stage of the project. As a family business with two decades of experience, we know how to make improving your home easy. You'll find our prices are extremely competitive and great value for money, and whether you are having new windows installed or a conservatory built, we will ensure that any disruption to your home is kept to an absolute minimum. You'll be admiring your new, improved home in no time..

Windows and Doors

Installing modern windows has a tremendous effect on the energy-efficiency, comfort and appearance of your home. PVCu offers a high-quality, lasting and practical solution that works exceptionally well in almost every property. RJM windows are hand-crafted to suit your home from materials specifically designed with the British climate in mind, virtually eliminating condensation while providing exceptional insulation against heat loss and external noise. Security is a key feature of our windows; with the latest high-security hinges and locks, you'll feel safer than ever before. Many people decide to have new windows fitted but forget about their doors. Retaining old, draughty doors can compromise the energy efficiency and security of your home even after you have had new windows installed. New doors can really enhance the appearance of your property and increase its value - and RJM doors are so simple and cost-effective to install.

We have an incredible range of virtually maintenance-free residential doors, including patio and French styles, all of which have full draught-proof seals to ensure that heat loss from your home is at an absolute minimum. Each one is compatible with the latest state-of-the-art high security hinges and locking gear, so you'll always feel perfectly secure, whichever style of door you choose.


A conservatory is an incredibly cost-effect way to create more space, light and functionality in your property. An RJM conservatory offers so much more than the simple addition of a room - it can revolutionise the way your home feels. We use cutting-edge technology to create conservatories that blend beautifully with your existing architecture, enhancing your home and adding significant value. The highest-quality materials are used, including triple-skin polycarbonate glazing sheets to ensure exceptional heat retention, PVCu-clad aluminium glazing spars that look fabulous and require almost no maintenance, and state-of-the-art roofing materials that offer brilliant long-lasting performance. And of course, our conservatories come complete with the highest-performance seals available, ensuring that they can withstand anything the British weather throws at them.

At RJM, we make sure that you get the conservatory you've always wanted. Only then will you wonder how you managed without it before... for further details, please visit our website, or call on 01726 816922
