Terms you may see on a drying log
- Moisture meter
- A pin or pinless device that reads moisture in wood, drywall and similar materials.
- Dry standard
- A reading taken from an unaffected area of the same material, used as a target.
- Thermal camera
- Shows temperature differences that can hint at wet areas; it does not measure moisture directly.
- Psychrometric reading
- Air temperature and humidity measurements used to judge the drying environment.
- Dehumidifier
- Equipment that removes moisture from the air during drying.
- Air mover
- A fan that moves air across wet surfaces.
What a log should tell you
A useful log lists the date, the location of each reading, the material, the number and the dry reference. Over several visits the numbers for wet materials should come down toward the reference. If they do not, something is wrong: a hidden source, a wet cavity that is not getting air, or equipment that is not suited to the room.
Colorado's dry climate may help drying in some conditions, but indoor humidity depends on the house, the weather and the equipment. Ask the contractor to explain how they will track conditions in your home.
A typical documentation rhythm
- First visit
- Baseline readings across wet and dry areas; equipment set up.
- Next day
- Repeat readings; adjust fans and dehumidifiers.
- Following days
- Readings continue until target values are met.
- Final visit
- Verification readings; equipment removal.
Questions to ask about readings
- What is the dry reference for each material?
- Will you share the log after each visit?
- How will hidden cavities be checked?
- What readings mean the job is done?
- Who decides when equipment can come out?
Limits of measurement
A meter reads near the surface and depends on the material. A number that is high on one product may be normal on another. No single reading stands alone, which is why the comparison to a dry reference and the trend across days matter more than any one number.
One more habit helps. Ask for a simple sketch or a list of the spots that will be read each visit, and mark them with small dots or tape so the same locations are measured again. Readings from different places can look like progress when they are actually unrelated. Consistent spots tell a clearer story, and the log becomes easier to hand to an insurer who was not there to see the work.
