Slider deadbolt seized, dock gate cylinder pitted
Saturday morning at Tropic Isle - waterfront homeowner called because both the canal-side slider deadbolt and the dock-gate cylinder had given up after the same humid week.
We replaced the slider deadbolt with a stainless-steel marine-grade unit, swapped the dock-gate cylinder for a marine-brass replacement (PVD-coated to resist pitting), and re-keyed both to her existing brass key. 75 minutes, $185.
Tropic Isle waterfront hardware has a service-life of about 18 - 30 months on cheap brass. Marine-grade replacements typically last 6 - 8 years.
