A peephole, also called a door viewer, gives residents a simple way to check who is outside before opening the door. SherlockLock helps homeowners, tenants, landlords, and property managers with compatible peephole installation, replacement, and residential door security review for apartments, condos, homes, and rental units across Boston and nearby Massachusetts communities.
Install a compatible door viewer at a practical viewing height based on the door, resident needs, and available hardware.
Replace worn, cloudy, damaged, loose, painted-over, or outdated peepholes when compatible replacement hardware is available.
Support peephole requests for apartment, condo, and rental doors when property rules and authorization allow installation.
Pair peephole installation with lock repair, deadbolt upgrades, chain locks, door guards, or other practical entry security improvements.
Review whether the door material, thickness, condition, and location are suitable for a clean peephole installation.
Help property managers, landlords, and tenants coordinate peephole service for move-ins, upgrades, and access-safety concerns.
Peephole installation may require landlord, HOA, condo association, or property management approval before drilling into a door. Some fire-rated, metal, glass, or specialty doors may need a different process or may not be appropriate for standard peephole hardware.
