A Closer Look at Mortise Lock Repair
Locks and door hardware are mechanical, and every mechanical part wears. Springs weaken, pins and cams round off, lubricant dries out, and doors shift on their hinges as a building settles. The early symptoms — a key that sticks, a bolt that drags, a handle that feels loose — are easy to ignore until the day the lock finally fails at the worst possible moment.
A proper repair means diagnosing the true cause rather than masking the symptom. We inspect the cylinder, latch, strike, hinges, and door alignment together, then fix what's actually failing and tune everything so it operates the way it did when it was new.
