Visually inspect corrosion, decay, movement, flashing and accessible fasteners.
Home system
Deck, stairs and guards as a system
Connect ledger, flashing, beams, posts, footings, frost, stairs, handrails and guards in one diagnosis.
Checked: 2026-08-21
New deck or stair/guard alteration: confirm dimensions, loads, foundations and local rules.
Detached ledger, unstable post/footing, structural decay or loose elevated guard: restrict use and obtain evaluation.
Useful tools and measurements
- Level, tape and square
- Awl/screwdriver for gentle wood inspection
- Photos of fasteners and flashing
- Layout and fall-height plan
Having a tool does not make regulated work DIY.
What the professional checks
- Verify load path to footings
- Size ledger/beams/joists/posts and connections
- Check stairs, handrails and guards to local code
