Quotes and Prices

At KJM, we strive to provide our customers with honest, good value quotations without pressure or obligation. To ensure this, our sales team are non-commissioned so they are able to provide honest guidance and advice. We don’t confuse matters with inflated prices and discounts. Instead, we keep our prices steady and quotations realistic. 

Range of Products

We work with a huge range of product lines and materials. Although uPVC continues to rise in popularity, we also provide aluminium and hardwood frames. Customers can choose from a broad range of styles to encase their double glazed units. Some buildings require windows and doors to remain in keeping with period features. Other projects prioritise functionality and durability. With so many choices to be made in colour, finish, function and style, why not view our ranges on display in our Andover showroom. As we offer so much choice, you can be sure to find a good quality window, door or conservatory product to fit any budget range. 

Eco-Conscious Supplier

For increasing numbers of projects, sustainability is a growing concern. We supply and install two lines which use recycled materials in their production. Profile 22 uses RCM (recycled composite material) to manufacture internal reinforcements. Similarly, the core of the Veka Infinity Window & Door profile system is constructed with recycled materials from old PVC window casements. KJM are committed to all parts of the recycling chain, so during window and door removal and installation, we separate waste materials for recycling. 

Unit Features


Low-E, or low emissivity glass is made by coating the glass panes. Our products feature a soft coating, which offers better clarity of light, improved light diffusion and better insulation performance. 


Swisspacer bars are a type of ‘warm edge spacer’ which insulate the edges of the glass panes within a double glazing unit. They prevent heat being lost from the edges of the double glazed panes and reduce condensation.


Sitting in between the panes of double glazing is gas. In days gone by this gas would consist of standard air, or dry nitrogen. Of course, technology has moved on and we now use Argon gas to fill the gap between panes of glass. This denser gas slows the movement of convection currents, preventing the heat from transferring to the outside of the panes.


Our products carry a warranty of 10 years. As finalists of Installer of the Year, we are able to provide our customers with confidence in the work and peace of mind in the ongoing use of their double glazing. We strive to provide our customers with the most suitable products for their project, which will offer great performance well into the future.
