Field library
Field guides for recording wood conditions, comparing observations and deciding what evidence to collect next.
Describe what you can observe before assigning a cause
A crack, stain or change in shape is a starting observation. Record location, extent, moisture conditions and changes over time, then identify which evidence can distinguish possible explanations. The illustrations teach observation; they do not diagnose a real installation.
Wood checking versus splitting: what to document
Document crack location, visibility, and change while keeping observed features separate from conclusions about cause or safety.
Wood cupping, bowing, crook and twist explained
Distinguish cross-width and along-length observations, record reference points, and investigate the assembly around the board.
Investigating stains on exterior hardwood
Use distribution, history, and controlled documentation to distinguish a visible color change from an established cause.
Investigating loose hardwood connections
Capture movement and component identity so a repair addresses the connection rather than simply changing the visible screw position.
Build a moisture investigation around locations and repeat readings
Use a documented measurement plan to investigate wetting patterns while recognizing the limits of a single moisture reading.
Separate finish appearance from the underlying condition
Document peeling, uneven color, tackiness, or wear before deciding whether preparation, exposure, or another factor needs investigation.
Create an evidence record that survives the repair
Organize locations, photographs, chronology, product records, and open questions without turning assumptions into findings.
Choose repair or replacement with an explicit decision record
Compare practical options after the condition is assessed, keeping appearance, function, and unresolved risk as distinct questions.
