KJM has always strived to provide the very best after-sales service.

Customer Care

However your products do require both cleaning and some minor maintenance (lubrication).


This section of our website should help you understand what is required and what products are best advised to use. In the menu above or to left (In this section) depending upon what device you are viewing this on, you will find further information on cleaning, maintenance, advice on condensation on double glazing, warranty claims and a link to some external websites who provide more useful information on our products.

We do have a full-time Service Engineer, who can carry out a service for you on your behalf, for a reasonable charge. We are also happy to provide quotations for replacement glass sealed units, replacement handles and locking mechanisms on both KJM and non-KJM products. Quotations are free.
