Considerations

The replacement installation process

What is it?

Existing joinery is removed entirely and a new window or door and framing structure is installed. It is a full replacement giving you the opportunity to completely change the colour, style and configuration of your windows and doors.

What's involved?

Existing joinery including facings, flashings and architraves are completely removed to leave one big clear opening. Where existing joinery is aluminium, the joinery and internal timber liner is removed. Where existing joinery is timber, all old timber joinery and framing is removed.

The opening is then prepared with flashing tapes and sill pans. New joinery is installed; plumb, level and square before it is fixed off.

External head flashings, facings, scribers (and decorative sills if required) are fitted. To stop draughts and air flow, an internal air seal is applied between the house framing and the new timber liner. Finally, the internal architraves are fitted and the joinery is cleaned.

Once installation is complete, you will need to fill and paint the interior liners and architraves, return furniture and reinstate your window coverings.
