Whilst we are flexible in our approach to how we work with clients, to ensure we provide the optimal window and door solution we follow a quality-assured quotation and order process which provides a solid foundation to any approach. Depending on whether you choose supply only or full project management, our process is outlined below:

Initial enquiry

Before we provide a quotation we would encourage you to supply drawings and/or specifications. To assist you in this, we have a dedicated Resource Centre which includes CAD drawings, technical data sheets, articles and NBS specs (click here to access).

If you are unsure of the specification and need advice, perhaps due to the bespoke nature of the project, we are happy to make an initial site visit.

Quotation support

We will provide a clear, detailed quotation that meets the requirements of your specification and also present you with any options that will help obtain better performance, aesthetics and value (i.e. designing out any unnecessary cost based on the original spec). Our estimators are always available to discuss the quotation in detail to allow you to review and develop the specification.

If required we can provide test data and timber samples to support the quote.


Upon receipt of an order, we will send a confirmation with detailed CAD drawings of the products in elevation and section views. To accompany the drawings we will also send an approval document which incorporates a specification check list for you to sign-off before we proceed to manufacture.

Manufacture and installation

Once the production drawings and approval document are signed-off we will progress to manufacture at our factory in Donington, Lincolnshire. We welcome visits by clients should you wish to come and have a look at your order being made.

If you have requested that we provide an installation package, then this will be carried out by our commercial installation team, certified to Achilles Building Confidence and Safecontractor®.

After sales support

Upon completed, we provide guarantee registration for all products and supporting maintenance guidance. In the unlikely event of a problem, we will carry out the necessary remedial work in accordance with our product guarantees.

In addition to the above process, we offer design services through a dedicated team who are on-hand to work on your timber window and door specification. This design support can include developing new variations of existing windows and door designs to deliver the aesthetics required but at no detriment to product performance.
