How to Do a DIY Home Security Audit in One Afternoon

The Burglar's Perspective

Walk around your home from the outside and ask: which door looks weakest? Which window is hidden from the street? Where would I hide while attempting entry? Is there lighting at every entry point? What's visible through windows? This mental shift reveals vulnerabilities invisible from a homeowner's perspective.

Exterior Door Audit

• Test each door for solid feel — hollow core doors need replacement
• Check deadbolt operation — it should extend fully with a firm click
• Inspect strike plate screws — pull on the plate, it shouldn't flex
• Check door frame for cracks or soft wood that would split under force
• Look for weatherstripping gaps that could allow tool insertion

Window Audit

• Test every ground floor window latch — many are worn
• Check for cracked or damaged glass that could be pushed in
• Identify any windows hidden from street view — these need additional security
• Test window sensors if installed — are they still communicating?
• Look for landscaping blocking window visibility

Lighting Audit

Walk your property at night. Every entry point should be illuminated with motion-activated lights. Check: front door, back door, side entries, garage, and pathway from street to door. Dark areas are cover for unauthorized entry. Replace burned-out bulbs immediately.

Garage Audit

• Test the interior door from garage — does it have a deadbolt?
• Check the emergency release cord — is it secured against outside access?
• Is the garage door sealed at the bottom? A gap allows tool insertion
• Is there a camera or motion sensor covering the driveway?

Creating Your Security Action Plan

After the audit, categorize findings: Quick wins (under $50, under 1 hour) — strike plate screws, window pins, bulb replacements. Medium projects (under $200) — deadbolt upgrades, window security film. Long-term investments — alarm system, access control, camera system. Tackle quick wins this weekend.
