A refurbishment reaches the final fortnight. The joinery is installed, the ironmongery is fitted, and the client walks through for an early look. Three door leaves have dents near the lock face, one has a gouge where something was leaned against it, and the frame at the main corridor has been scraped down to bare timber on both sides.
None of this happened during the door installation. It happened afterward, while everyone else finished their work around it.
Why Doors Absorb So Much Damage
A door sits at the point where every route through a building narrows. Everything that enters or leaves the space passes through it, usually while someone is carrying something awkward.
That geometry explains the damage pattern. The leading edge of a plasterboard sheet catches the frame. A trolley strikes the leaf at wheel height. Someone props a door open with a tool bag and the hinge takes a load it was never designed for. Materials get rested against door faces because they are the nearest flat vertical surface.
Frames take worse punishment than leaves, and they are harder to repair. A dented leaf can sometimes be filled and refinished. A crushed frame reveal generally cannot be fixed to a standard anyone will accept, which means removing architrave, replacing sections, and refinishing a joint that will be visible under raking light.
Finished Doors Arrive Too Early
The scheduling problem behind most of this is that doors go in before the work that endangers them is complete.
Fire doors in particular cannot be left until the end, because they are part of the compartmentation strategy and their installation often needs to precede ceiling closures and final inspections. Ironmongery follows. Decoration follows that. Meanwhile the building is still full of trades moving materials.
The alternative, installing doors last, sounds sensible and is rarely practical. It delays handover, complicates sign-off, and creates a bottleneck in the final week that nobody wants. So the doors go in and sit exposed through the busiest traffic period of the whole programme.
Arranging temporary door protection during construction is what covers that interval, and the point to specify it is when the installation is being scheduled rather than when the first damage is spotted.
Protecting The Wrong Parts
A common half-measure is covering the door face and leaving everything else exposed.
The face is not where most damage occurs. Edges take impact. Frames take impact. The lock face and hinge edge concentrate stress from repeated use and from doors being forced past obstructions. Thresholds get dragged across.
Protection that covers only the flat surface addresses the least vulnerable area. Anything worth installing needs to wrap edges, cover the frame reveals, and protect the threshold, because those are the components that fail expensively.
Vision panels are their own case. Glass is easy to crack, and on fire-rated doors the glazing and its beading are part of the certified assembly. A damaged vision panel is not a glazing repair. It may compromise the door’s rating.
The Tape Problem
The most self-defeating mistake is fixing protection to the finished surface with adhesive tape.
On a freshly finished door, the coating has not fully cured. Tape applied to it can bond more strongly than the finish bonds to the substrate, so removal lifts paint or lacquer and leaves a mark worse than the one being prevented. The same applies to factory-finished leaves and to veneers, where tape can lift a face layer.
The workable method fixes protection to itself rather than to the door, using wraps and ties that hold under their own tension. Where adhesive is unavoidable it goes on the protection material, not on the surface being protected.
The second issue is leaving protection in place too long on a door that is still curing. Sealed coverings over uncured finish can trap solvent vapour and cause discolouration. There is a sensible window, and it belongs in the plan alongside everything else.
Ironmongery Is Easy To Overlook
Handles, closers, hinges, and locks are individually expensive and easy to damage.
Lever handles get struck by passing loads. Closer arms get bent when doors are forced open past their travel. Cylinder faces get scratched. Hinges get strained by props and wedges.
Doors held open with wedges during the fit-out period take particular punishment, because a door stopped at a fixed point becomes an obstacle that people push past rather than a moving part. The load goes into the hinges and the closer.
Where doors need to stay open for access, temporary retaining arrangements that release under normal force cause less damage than a wedge and less disruption than a door constantly swinging into traffic.
Who Owns The Risk
Responsibility for door damage during the final phase is frequently undefined, which is why it ends in argument.
The joinery subcontractor installs and leaves. The main contractor assumes the following trades will be careful. The following trades are working to their own programme and have no particular stake in surfaces installed by someone else.
Damage discovered at snagging is often unattributable, and unattributable damage is absorbed by whoever has the least leverage in the conversation. That is usually the party holding retention.
Resolving this before installation is a short conversation with a real financial outcome. Who supplies protection, who fits it, who maintains it through the programme, who removes it, and who carries the cost of damage occurring while it is meant to be in place.
Three Things To Confirm
Check that protection covers edges, frames, and thresholds rather than faces alone, and that vision panels and ironmongery are included.
Check that the fixing method involves no adhesive contact with any finished surface, and that there is a defined removal point rather than an assumption that it comes off at the end.
Check that responsibility for damage during the protected period is written down, including for trades and vendors working outside the main contract.
Doors are among the last items installed and the first things a client inspects closely. The interval between those two moments is short, unmanaged, and where nearly all of the damage occurs.
