Transforming Homes, Enriching Lives
At RJM Windows, we pride ourselves on being a family-run business that has been serving the people of Cornwall since 1986. Our founding directors, Rob and Julie McKane, had a vision to provide high-quality, cost-effective home improvement solutions to the local community. Their background in joinery and real demand for quality home improvements led to the creation of RJM Windows.
Over the years, we have continued to grow and adapt to the changing needs of our customers. In the 1990s, we scaled up to larger premises and invested in cutting-edge machinery to make the transition to uPVC products. In 2004, we moved to larger premises and invested in pioneering glass processing machinery. Today, we are proud to be one of the few remaining manufacturers based in Cornwall, offering a comprehensive range of products, including uPVC frames and sealed glass units, and industry-leading aluminium home improvement products.
Our Services
At RJM Windows, we offer a wide range of services to our customers. From traditional Cornish cottages to new build developments, we have a versatile collection of uPVC frames and slender aluminium windows that can add character and style to any property. Our refined range of products includes:
- Casement Windows

We also specialise in the installation of conservatories, with styles to suit every taste and budget. Whether you need extra space for a growing family or want to transform a worn-out, cold and draughty conservatory, we can help.
In addition, we offer a range of tiled roofs, including the award-winning Guardian Warm Roof System, the highly respected Ultraframe roof, and the esteemed Eurocell Equinox roof.
