High Security Doors

Step 1

On meeting with the client and establishing the requirements for your new security door, we create an estimate to include the supply, finishing and fitting (where required) for the structure. We do try and take as many details as possible at this stage so that this initial quote is accurate, and in most cases, will not alter throughout the process.

Step 2

Once you are happy with the quote we will take a deposit for the order and (and assuming we are to fit the new door) arrange for a site survey to be carried out to establish accurate measurements and any special requirements to ensure a smooth fitting. We are happy to work alongside your contractors if openings are to be made, but insist on a site survey to eradicate any future issues that may arise if this is not carried out.

Step 3

An approval drawing is created to ensure that positioning of door furniture and opening direction is correct – and we are all happy with the look of the door.

Step 4

Once approved, production is confirmed and a fitting date is arranged.
