Basically you give us as many details as you can we will then ask all relevant questions regarding the details you have not given us, then when we have all the details we produce full CAD drawings of your door with sizes and details for you to approve before anything is made.

How to measure

A lot of people are frightened of measuring because they are expensive all you need to remember is it is just a square.

We can and will talk you through it and if we are not 100% satisfied that you are confident or unsure then we will organise a surveyor to come survey for you.

We do this many ways for many different clients even as simple as someone holding the tape measure at one end while someone is holding it at the other end and a photograph is taken, then the images are sent to us.


This is very important when ordering a door you must consider whether the door can be taken to it point of installation in one big piece if not it is not a problem we do send staff to bring it in pieces and then build it up in the garden for you but we must be aware of this.


If you are building an extension and are ordering a roof lantern or bi-folding door and you want a couple of windows to match in aluminium we can make these as well.
