Caulking and sealing fills gaps and joints around windows, doors, bathtubs, sinks, and exterior penetrations to prevent water intrusion, drafts, and pest entry.
In practice
You'd see this when a property manager gets a maintenance request about water leaking under the kitchen sink.
Why it matters
Caulking is preventive maintenance that protects against water damage.
Common questions
How do I know when caulk needs replacing?+
Cracking, peeling, discoloration, or visible gaps between surfaces.
Can I caulk over old caulk?+
It's not recommended. Old caulk should be removed first for a proper seal.
