What humidity is too low in a house? Under about 30% relative humidity. How to confirm it with a hygrometer, what dry air does to timber, and how to fix it.

Why do two hygrometers show different readings? Tolerance, heat, thermal lag and placement explained, plus a fair side-by-side test to find the culprit.

How to log humidity at home: record RH and temperature for seven days, note events, then read the pattern to choose ventilation, a dehumidifier or a leak check.

Damp meter readings explained: what %MC, WME and relative scales mean, five causes of false highs, and what to do after a dry, borderline or wet result.

Where to put a hygrometer so the reading is true: mid-room at chest height, clear of windows, radiators and steam. Plus when a cold wall is the right spot.

How to use a damp meter: take readings at several points, compare them with a dry reference wall, avoid foil and metal, and treat a high number as a prompt.

How accurate are hygrometers? Usually within 2 to 5 points when new, then drift and damp-air error. Why a few points rarely changes a damp-house decision.

Bathroom door open or closed after a shower? Shut while the fan runs, then open once it clears. The 4-step order, and what to do with no fan.

How to reduce humidity without air conditioning: stop making steam, dry washing elsewhere, air the house at the right hour. 7 easy ways, and 2 that fail.

Can you vent a bathroom fan into the loft? No: the steam condenses on cold timbers. What the guidance says, where the duct should end, and 5 checks to make.

How to ventilate a room with no windows: a ducted extract fan, a gap under the door for replacement air, and where a dehumidifier helps. 5 fixes, plain rules.

Why does my bathroom stay damp all day? The fan clears steam, but cold tiles, wet towels and grout hold water for hours. Six causes and the order to fix them.
