After handing over dozens of commercial and residential projects, many contractors notice a recurring pattern: the most common post-occupancy complaints are not about aesthetics, but about doors that gradually become harder to open or close. Tenants report stiff handles, maintenance teams get called repeatedly, and warranty periods turn into unexpected expense periods.This issue is especially common with keyed lever door handles in buildings with high daily traffic.

On large projects, installation cost is rarely just about labor hours. It often comes from small delays, repeated adjustments, mismatched hardware, and the time spent fixing issues that should not have happened in the first place. When dozens or even hundreds of doors are involved, these small problems add up quickly.
