Now you have your windows or doors, it's time to get them installed. Download our handy installation guide to help you if you decide to install your windows or doors yourself. We would always recommend that either a qualified or competent person should carry out the installation.

​Always remember to check your new frame before you begin the installation by measuring it against the aperture where it will be installed. We would advise to start with the smallest frame first and always start by removing the existing glass.

When measuring your existing windows and doors it is important to remember that we need the brick-to-brick sizes of the opening the window/door is in. Always measure the aperture from the outside and in three separate locations for the width and height and record your measurements in millimetres (mm). Take the smallest of the three measurements and deduct 10mm for white frames and 15mm for any coloured frames.

When you provide us with your frame measurements they will need to include the frame, cill and any frame extenders or add ons that are required.

For a step by step guide on how to measure your windows and doors please download our guide to measuring. It is important to make sure that measurements are correct before ordering your supply only composite doors and diy upvc windows. Alternatively, we have made a short window and door measuring tutorial video to help you with the measuring process.
