El Cajon, Santee, and Lakeside homes, mostly standard prep work, occasional wildfire-zone homes in Alpine and Jamul where we install reinforced strike plates with 3" screws into the framing..
What brand of deadbolt should I install?
For ANSI Grade-1: Schlage B60/B62 series, Medeco Maxum, Mul-T-Lock Hercular. For ANSI Grade-2: Kwikset 980/985, Schlage B250. Avoid builder-grade Kwikset 600-series and anything Grade-3 on an exterior door. We'll match the finish to your existing hardware.
Is a Grade-1 deadbolt actually safer than Grade-3?
Yes, measurably. Grade-1 survives 10 impact strikes from a 100-lb load; Grade-3 fails at 2. The cylinder pick-resistance difference is even bigger. But hardware alone doesn't protect you, the strike plate and door frame matter as much. We upgrade all three.
