In a nutshell

There are two things we are passionate about at LJS, quality craftsmanship and excellent customer service. And we don’t believe you should have to go far to get it. Based in the heart of Lincoln, we specialise in manufacturing and supplying bespoke high performance windows and doors and with over 20 years’ experience our customers can feel confident in the service we provide.

Our Ironmongery

Careful consideration goes into the final touches on our windows and doors, we will offer advice on what styles and options you have available to you, and as with our windows and doors the end result is beautiful but practical.

For those with security in mind we can supply ironmongery which is police endorsed ‘Secured by Design’ on all our high performance windows and doors for additional peace of mind laminate glass can be installed.


Our Timber

We use a laminated engineered timber to ensure that every piece of joinery is defect free. It is designed to eliminate warping and twisting, as well as impurities such as knots and centre pith that can be found in natural wood.

We use Accoya wood which lasts an incredible 50 years above ground and 25 years in ground for the ultimate in longevity. It is 100% recyclable and sourced from sustainable forests.

Our Technology

Our joinery shop is equipped with the very latest Swiss made ‘Oertli’ window and door tooling which works in synchronisation with our state of the art Italian SCM CNC machinery.
We use cutting edge technology for our quotation/estimate service and modern design software to plan everything from flush-fitting casement windows to more elaborate designs and curve-work.
