Where it goes

Fitted in the door you have.

Most flaps sit in a uPVC door panel or in the double glazed unit itself. We cut a clean hole, seal it and fit the flap, in back doors, front doors, French doors and conservatory doors.

  • uPVC and aluminium framed doors
  • Double glazed glass units
  • Flat uPVC panels, half or full length
  • French door sets and some sliding patio doors

How it works

  1. 01

    Tell us about the door

    Call the office or send a photo. Let us know the door type, whether the flap is going in the panel or the glass, and the flap you have in mind.

  2. 02

    We make it to size

    For glass, we make a new sealed unit with the hole cut and sealed. For panels, we supply a half or full-length uPVC panel ready for the flap.

  3. 03

    Fitted in one visit

    We fit the panel or unit and the flap in the same visit.
