uPVC doors
uPVC doors cost roughly £700 to £1,400 fitted, making them the cheapest full replacement. They suit back doors, utility doors and side entrances well, and work as a front door on a budget, though they feel lighter and less solid than a composite door.
uPVC gets dismissed because it is cheap, which is unfair to it. For a back door that gets opened twenty times a day and sits behind a gate, it is often exactly the right specification.

Where uPVC makes most sense
Back doors, side doors, utility and garage-side entrances are where uPVC is at its best: low maintenance, reasonable security, easy to glaze for light, and not expensive to replace if it gets damaged.
As a front door it is a compromise rather than a mistake. The panel is thinner, the door is lighter, and it does not have the solidity people associate with a secure entrance, but a well-specified uPVC door with proper locking is still a sound door.
Panels, reinforcement and sagging
The common failure on a cheap uPVC door is dropping on its hinges, which then stops the multi-point lock engaging cleanly. It is caused by an under-reinforced outer frame or undersized hinges carrying a heavy glazed panel.
Ask about galvanised steel reinforcement in the frame and sash, and about adjustable hinges. Both are inexpensive and both prevent the problem that makes people replace these doors early.
Security on a budget
A cheap uPVC door is only as good as its cylinder, and cylinder snapping is the most common way they are defeated. An anti-snap cylinder is an inexpensive upgrade that makes a disproportionate difference.
If the door is glazed near the handle, specify laminated glass there for the same reason it is specified on a composite door.
uPVC doors: common questions
- Are uPVC doors secure?
- A modern uPVC door with a multi-point lock and an anti-snap cylinder is reasonably secure. The cylinder is the weak point on older doors, and upgrading it is cheap relative to the protection it adds.
- Why has my uPVC door stopped locking?
- Almost always because the door has dropped slightly and the lock points no longer line up with the keeps. It is usually a hinge adjustment rather than a new door.
- Can uPVC doors be painted?
- Specialist uPVC paints exist and can work on a well-prepared frame, but the finish is not as durable as the original and it is rarely worth doing on a door that is already failing.
