Most break-ins — by the living or otherwise — come down to the same weak points: a door that gives way on the first kick, a window with no alarm, and no early warning that something's approaching. None of the fixes below require a contractor, and most go in with a screwdriver.
1. Reinforced Door Strike Plates
The factory strike plate on most exterior doors is held in with screws barely longer than the door trim. A 3-inch security strike plate anchors into the actual door frame stud, turning your front door from "one good kick" into "not happening."
Heavy-Duty Door Reinforcement Kit
The single highest "security per dollar" upgrade on this list, full stop.

2. Battery-Powered Window & Door Alarms
A loud, immediate alert the moment a window opens buys you time to react — and is often enough on its own to make an intruder reconsider. Stick-on sensors need no wiring and move with you if you relocate.
Ring Alarm Contact Sensor — 6-Pack (Door & Window)
Cover every ground-floor window and door for less than a single deadbolt.

3. Adjustable Security Door Bar
A floor-braced bar across an exterior or interior door adds a second layer that doesn't depend on the lock at all. Useful for safe rooms, sliding doors, and as a backup if a lock is ever compromised.
Adjustable Security Door Bar
Great for rentals — no permanent modification to doors or frames.

4. Motion-Sensor Floodlights
Light is one of the cheapest deterrents that exists. A motion-triggered floodlight on every approach to the house — front door, side gate, back porch — removes the cover of darkness before anyone gets close.
Lepro 27W 3-Head Motion-Sensor Security Light
Three independently adjustable heads cover a full driveway or back porch. Motion-activated, so it stays off until it's needed — your first line of early warning without lifting a finger.

5. Window Security Film
A clear adhesive film that holds shattered glass together instead of letting it fall away. Doesn't make a window unbreakable, but turns "smash and reach through" into "smash and... it's still there."
Security Window Film (Clear, Multi-Pack)
A weekend project that covers every ground-floor window in the house.

Putting It Together
Start at the front door — it's the highest-traffic entry point and the cheapest fix on this list. Then work outward: alarms on accessible windows, lights on dark approaches, and film on anything ground-floor and glass. A weekend and a modest budget gets every entry point on the property meaningfully harder to breach, whether the thing trying to get in has a crowbar or no pulse at all.
