How often should you really repaint your home?

Most repaint advice quotes a flat "every five to seven years". That is a reasonable average across a whole house, but it is useless room by room. A guest bedroom can look new at year ten while a hallway is visibly tired at year three.

A realistic room-by-room schedule

• Hallways & stairwells — 3 to 5 years. Constant contact and scuffing.
• Kitchens — 4 to 6 years. Grease and steam degrade the film.
• Bathrooms — 4 to 6 years. Humidity is the limiting factor.
• Living areas — 6 to 8 years, longer if the room gets light use.
• Bedrooms — 8 to 10 years. Usually the last rooms to need attention.
• Ceilings — 8 to 12 years, unless there has been a leak.
• Exteriors — 5 to 10 years, heavily dependent on climate and aspect.

The signals that override the calendar

Timelines are a planning tool. The surface itself tells you when it is actually due, and it is worth learning to read.

• Chalking — a powdery residue on your hand after touching an exterior wall.
• Hairline cracking or "alligatoring" across a previously smooth surface.
• Colour drift, most obvious where a picture frame has shielded the wall.
• Marks that no longer wipe clean, because the film has worn through.
• Any peeling, blistering or lifting — this one is urgent, not cosmetic.

What extends the interval

The quality of the preparation determines lifespan far more than the price of the paint. A premium product over dusty, glossy or damp substrate will fail early; a mid-range product over properly cleaned, sanded and primed substrate will outlast it comfortably.

We would rather spend an extra day on prep than come back in two years. Prep is the part of the job you never see and always notice.

Good airflow, prompt attention to leaks, and washing exterior walls once a year all add measurable time between repaints — usually more than upgrading a paint tier does.
