The home inspection most owners skip — and what gets missed every year

This desk already ships the once-a-season checklist product — ten checks, progress saved in your browser. This page is the complement: the honest guide to what gets missed, the inspection angles no checklist quite captures, and the reasoning that makes you your own best inspector. The professional surveys — full structural, electrical condition reports, roof inspections — have their place, and the links below say where the line sits.

The blind spots, by elevation

The loft/attic is the most-skipped room in any house, and it's the archive of everything the roof has been doing: daylight where it shouldn't be, water staining on rafters or the insulation matting down where a leak has run, wasp or rodent traffic, and insulation that's been moved by someone standing in the wrong place. One look per season, with a torch, takes ten minutes. The ground outside is the second archive: the ground should slope away from the walls; puddles that sit against the house after rain are writing next winter's damp ticket (gutters feed this story). Behind and under — behind the washing machine (where slow leaks live), under every sink, inside the meter cupboard, behind the fridge (where the coils live). Water and heat damage announce themselves early in exactly these places, and never anywhere convenient.

The senses, used properly

Smell is the most underrated inspection tool: mustiness means moisture somewhere you haven't found (start with airflow); the hot-plastic or fish smell means electrics (stop and take it seriously); gas smells mean out and call, immediately. Sound: the running-meter test (the EPA's two-hour method), new rattles in the boiler cupboard, the toilet that refills when nobody used it. Touch: warm faceplates, cold patches on walls in heated rooms (cold walls are where condensation lands), and the door that's started to catch where it never did — houses move slowly, and skin notices before eyes do.

What genuinely needs a professional

The self-inspection has a boundary, and pretending otherwise is how people get hurt: the consumer unit and anything electrical beyond the visible (UK electrics are regulated for a reason); the roof slope and anything at height; gas appliances beyond the flame check (the annual service exists); structural movement beyond hairline; and drainage that backs up. The rhythm that works: your hour, four times a year, feeds the small fixes list — and the professionals' visits (boiler service, electrical check on its cycle, chimney sweep if you have one) sit on top of it.

Make it a habit that survives

Attach the walk to a date that already exists — the clocks changing, the boiler service, the first warm weekend — and take photos of everything you checked. The photo archive is the quiet superpower: when something does go wrong, dated pictures of the before-state win arguments with insurers and buyers' surveyors alike. Ten checks are waiting in the checklist product; the misses on this page are the eleventh through fifteenth.
