In most cases yes. Hinges, screw ports, handles, locks, cylinders, closers, gaskets, thresholds and glass panels are all individually replaceable. Replacement of the frame section itself is only necessary when the extrusion is bent or split from impact, when corrosion has gone through the metal rather than sitting on the surface, or when the profile system is obsolete and no matching hardware is still made.

Aluminium expands measurably as it heats, and a door set with tight clearances will bind once the frame and leaf both grow. If it closed cleanly in winter, the hardware is probably fine and the clearance is the problem. Forcing it through the hot months is what turns a simple adjustment into stripped hinge fixings, so it is worth dealing with before August rather than during it.

The thread has stripped out of the hollow section, so a threaded insert or repair sleeve is set into the profile to re-establish a proper thread for the hinge screw. Fitting a longer or thicker screw instead removes more of the remaining material and pushes the job toward replacing the section. If a screw is already spinning, stop turning it — that is the point at which the repair is still small.

Small chips can be touched up with a matched coating, and near the coast it is worth doing because exposed aluminium at a scratch is where corrosion begins. Long or deep scratches are harder — powder coating is a surface layer rather than a paint film, so it cannot be sanded and blended, and matching a weathered finish across a section rarely looks convincing. Proper recoating means removing the section.

Yes. The panel is measured, remade to size and refitted into the existing frame with new gaskets or beads. Toughened glass cannot be cut after manufacture, so a replacement panel is made to the measured size from scratch rather than trimmed on site — which is why an accurate survey matters more than the fitting does. The frame only needs work if it is distorted or corroded.

Four things, once or twice a year. Clear dust from tracks and drainage slots. Check hinge and frame fixings for movement before they strip. Inspect gaskets for hardening and cracking, particularly on south and west elevations where ultraviolet does the damage. And on coastal properties, look at fixings and thresholds for white corrosion bloom, which is the earliest warning you get.

Often, but not always. Aluminium profile systems are discontinued over time and their matching hardware goes with them. When a system is obsolete the options are adapting a current equivalent, which works for some hardware and not others, or replacing the door set. Sending photographs of the hinge, lock and any visible profile markings is usually enough to establish which situation you are in.

Both, and commercial entrances. The practical difference is access rather than the work — apartment buildings in Dubai usually require building management clearance, agreed working hours and sometimes a service lift booking before anyone arrives, and rented units need the landlord's permission first. Villa work has none of that, so it is generally quicker to arrange.
