About Us

About Us

J Paterson The Window Company – Quality and Service Assured

We have been specializing in the installation of replacement Rehau window and door systems since 1998. All our work comes with a ten year guarantee with deposit protection and insurance backed guarantee. Just recently our sealed units have been made with Super Spacer bar which have a twenty year warranty. We are the only Independent Warranty Association member to achieve 14 merit awards for customer satisfaction since 1998. This underlines our commitment to providing a quality service to our customers. To view our most resent customer satisfaction reports these can be viewed on Checkatrade.

Just recently we have become Solidor Premium Installers with a range of composite doors on show in our showroom in Whitstable and been vetted by Which as a Trusted Trader and for the past six years Trading Standards Approved.

Unlike most double-glazing companies, we do not employ representatives who only want you to sign on the dotted line after they have bored you to tears until 2 am in the morning.

Designs To Meet Your Budget, Ideas and Goals

Although we cannot say we are neither the cheapest nor the dearest, we promise that we will listen to your views and ideas. We will always offer you a choice of ideas as to window designs that will achieve the best look to compliment your property, show you a window sample and quote you right away – no hassle sales, no pressure and the choice, of course, to let us take on your project, is entirely yours.

All of our products are installed using our very own work force, so you can rest assured that we will never allocate subcontractors.

All of our new members of staff are given in-house training and are fully vetted by Mr Paterson himself. This ensures that we provide only the level of design and fitting that we have strived to meet on every single on of our window, door and conservatory projects.

We also welcome any feedback from our customers to improve our service further, and we consistently review feedback and change anything we see that our customers have not been happy with.
