Crime and security context
Mitcham and Colliers Wood see persistent residential burglary — internal deadbolts recommended. We strongly recommend pairing any cylinder upgrade with an internal deadbolt on rear doors, key-locking handles on ground-floor windows, and a visual review of side and back gates. Every visit includes a free top-to-bottom security review with no obligation.
