Garage
Garage door + opener + storage + often a workshop. The most common actual home injury site (heavy doors, sharp tools, chemicals). Safety framing throughout.
Overview
The garage combines a heavy mechanical door, chemical storage, workshop tools, and often a vehicle — making it statistically the most injury-prone room in the home. Understanding what's DIY-safe and what requires a professional matters more here than almost anywhere else.
The garage door itself is deceptively dangerous — a residential torsion spring stores enough energy to seriously injure or kill. Sensor issues and remote programming are DIY-safe; spring replacement, cable work, and off-track doors are always professional.

Garage door: what's DIY, what's not
Safe DIY: Sensor cleaning/alignment, remote programming, weatherstripping replacement, opener replacement (with power off), lubrication of hinges/rollers.
Always pro: Torsion spring replacement, cable replacement, off-track doors, door panel replacement, opener chain/belt tension work. Torsion springs store enough energy to kill — no home repair project is worth that risk.
Frequently asked questions
10,000–20,000 cycles depending on quality (about 7–12 years of normal use). When one breaks, replace both — the other is close to failing and the labor is the same either way. Always professional replacement — $250–$450 per pair.
Yes — code requires GFCI protection on all garage outlets. If your garage outlets aren't GFCI-protected (either at the outlet or upstream), upgrade for safety.
Yes for basic 1-part epoxy kits — 1 weekend, $200–$500 in materials. 2-part professional-grade epoxy is more durable but requires precise application. For premium finishes (metallic, flake, high-gloss), professional install is worth the cost.
Must be a fire-rated door (typically 20-minute or 1-3/8 inch solid core), self-closing (spring hinges), and open into the house. Weatherstripping required on all sides. See garage-to-house door code.
