Carpet care guidance often suggests a professional clean every 12 to 18 months for a typical household. That's a reasonable baseline, but real homes vary a lot. A retired couple with no pets can go much longer than a family with two dogs and three children.
A rough guide by household
| Household | Suggested deep clean |
|---|---|
| Low traffic, no pets or children | Every 12 to 24 months |
| Typical family home | Every 12 months |
| Pets in the house | Every 6 to 12 months |
| Allergy or asthma sufferers | Every 6 to 12 months, plus thorough vacuuming |
| Rented property | Between tenancies |
| Holiday let | At least once a season, plus spot cleaning |
| Busy office or shop | Every few months in walkways (see commercial cleaning) |
These are only rough guides. The carpet itself will tell you when it needs doing.
Signs your carpet needs cleaning
- Grey or dark traffic lanes in hallways and in front of the sofa
- Flattened pile that doesn't spring back after vacuuming
- A stale or "doggy" smell, especially when the heating is on
- Stains that keep reappearing after spot cleaning
- Allergy symptoms that seem worse at home
Why regular cleaning makes carpets last longer
Grit in a carpet acts like sandpaper. Every footstep grinds it against the fibres, slowly cutting and dulling them. Oily soil makes things worse by holding grit in place. Regular deep cleaning removes both before they do permanent damage, which is why carpets that are looked after can last years longer than those that aren't.
Habits that keep carpets cleaner between visits
- Vacuum high-traffic areas at least twice a week, and more often with pets.
- Use good doormats inside and outside every entrance.
- Take shoes off indoors.
- Deal with spills straight away by blotting, not rubbing. Our stain removal guide explains how.
- Move furniture slightly every so often so the same spots don't take all the pressure.
