R.J.M Windows

We are a family run business who have been trading in Mid Cornwall and Devon for over 30 years. All upvc products are manufactured in our factory as well as all glass sealed units. We are one of the few remaining manufacturers left in Cornwall, but we feel passionate about this side of our business. We find it gives us more control over supplying you, our customer with great products and more flexible lead times. On the following pages we will show you some of the choices available to you in terms of window and door options, coloured profile, glazing options and hardware choices.

We provide glass balustrades and Juliette Balconies. Our system can be fitted to decking, paving, brickwork and GRP flat roofs. Our glass staircases are made with toughened glass and can be finished with either stainless steel or wooden handrails. Manufactured to the highest standard and using marine grade stainless steel. Do you have an amazing view but your window is too small? By removing your window, replace with either French doors or patio doors and adding a glass balcony, your room with be filled with light and give you an uninterrupted view.

The revolutionary Guardian Roof is a step forward in home improvement. A high performance, lightweight roof system that has been designed to replace your existing glass or polycarbonate roof or to be installed as an alternative on your new conservatory.

We specialise in making homes like yours more secure and beautiful. We achieve this by manufacturing our own upvc windows and doors to an exceptional standard. Our products are energy efficient by being either double or triple glazed. So whether you're looking for more of a wow factor, more security or to add value to your home, we'll help you achieve your aims. The products we manufacture and install are high quality, well tested and well trusted by home owners across Cornwall and Devon.
