Door Security Reality Check

Why doors are the #1 target and how reinforcement stops break-ins

Break-in Statistics & Methods

🚨

Entry Point Statistics

70% through doors: Front, back, garage

23% through windows: First floor access

4% through basement: Hidden entry

3% through garage: Direct house access

Average time: 2-3 minutes total

⚡

Forced Entry Methods

Kicking: 95% of door break-ins

Tool prying: Crowbar, screwdriver

Lock picking: Less than 2%

Key theft: Family/workers

Weak point: Strike plate area

⏱️

Time Delay Impact

0-60 seconds: 90% persist

1-3 minutes: 50% give up

3-5 minutes: 20% continue

5+ minutes: 5% persist

Goal: Add 5+ minutes resistance

Critical Fact: Standard doors fail in 1-2 kicks because the strike plate tears out of the frame. A $50 reinforcement upgrade can add 5+ minutes of resistance, causing 80% of burglars to give up.

Frequently Asked Questions

Expert answers to common door reinforcement questions

Will door reinforcement work with smart locks?
Yes, door reinforcement actually enhances smart lock security. Smart locks rely on the same strike plate and frame strength as traditional locks. Reinforce first, then install smart locks for maximum security. Many smart locks require Grade 1 deadbolt mechanisms anyway.
How long does professional installation take?
Professional strike plate installation typically takes 45-90 minutes per door. Complete door armor kits require 2-3 hours. Steel frame installation or door replacement can take 4-6 hours. Multiple doors on the same visit often get discounted labor rates.
Can I reinforce doors without damaging the frame?
Modern reinforcement systems are designed to strengthen, not damage frames. Long screws anchor into solid studs behind the frame, actually reducing stress on the frame itself. Poor installation can cause damage – pilot holes and proper tools prevent frame splitting.
What’s the difference between door armor brands?
Quality varies mainly in steel thickness and hardware grade. Door Devil and Armor Concepts use 12-gauge steel vs. cheaper 16-gauge options. All reputable brands provide significant security improvement – choose based on door type and budget rather than brand prestige.
Should I reinforce all doors or just the front door?
Prioritize based on accessibility and visibility. Front doors are obvious targets, but back doors and garage entries are often easier targets with less visibility. Start with the most vulnerable door, then work through all ground-level access points.
How much insurance discount can I get for door reinforcement?
Door reinforcement alone rarely qualifies for discounts, but it’s part of comprehensive security that can earn 5-20% discounts. Document all security improvements with photos and receipts. The real value is preventing claims – one break-in costs far more than all reinforcements combined.
