Door Realignment – the Most Common Cure
uPVC and composite doors drop over time – the weight of the glass and daily use gradually pull the door out of square. When that happens the lock stops lining up with the keeps, the door scrapes the frame, and draughts appear.
In most cases we can realign the door on its hinges and adjust the keeps in a single visit, restoring smooth closing and secure locking. No new door needed.
Repair Beats Replacement
A replacement composite door can easily cost four figures. A realignment or a new mechanism costs a small fraction of that and adds years of life to your existing door. We will always tell you honestly if a repair is the better option – and with no fix, no fee, you risk nothing by asking.
