Cleaning, seal, hinge and lock maintenance, thresholds and winter care.
Exterior doors are among the most frequently used parts of a home. They are opened and closed dozens of times a day, facing cold and snow in winter and sun and rain in summer. A little regular care is therefore particularly useful. This article explains what to do, how to do it and what to look out for.
A door depends on several parts: the surface, frame, seals, hinges, lock and threshold. If one wears out or becomes clogged, the door can become difficult to close, draughts may appear or thermal insulation may deteriorate. Regular inspection and cleaning can prevent many of these problems.
Clean with warm water and a mild detergent, using a soft cloth or sponge. Do not use abrasive products, metal brushes or solvents, as these can damage the surface.
Aluminium surfaces resist the weather, but benefit from regular removal of dust and dirt, particularly at frame joints. Use a mild cleaner and a soft cloth.
If the door contains glass, clean it with a standard glass cleaner in the shade or on a cloudy day to avoid streaks.
Seals help the door close tightly and keep out cold air in winter. Inspect them once a year:
A dedicated seal-care product or silicone lubricant can help maintain elasticity. This also helps prevent the seal from freezing to the frame in winter.
Hinges carry the weight of the door and are under particular strain. Once a year, preferably in autumn:
If the door rubs against the frame or becomes difficult to lock, adjusting the hinges is often enough. This is quicker and less expensive than replacing the door.
The lock mechanism needs the right lubricant. For the cylinder, use a dedicated lock lubricant or graphite product rather than ordinary oil, which attracts dust and may make the mechanism harder to operate over time. Follow the cylinder manufacturer’s instructions, as graphite is not suitable for every type. If the key becomes difficult to turn, do not force it; first clean and lubricate the mechanism as instructed.
Sand, leaves and dirt collect at the threshold. They can prevent the door from closing tightly and damage the seal. Clean the threshold regularly and check that any drainage holes are not blocked.
In spring
Thoroughly clean the door surface, frame and threshold after winter; inspect seals and check for winter damage.
In autumn
Lubricate hinges and hardware; maintain the lock mechanism and check for draughts before the heating season.
From time to time
Notice whether the door closes and locks easily, and watch for any changes in how it works.
It is worth getting an assessment. Sometimes adjustment or replacing parts is enough, while in other cases replacing the door is more cost-effective.
