Carpet is usually the single most expensive surface in a commercial fit-out, and the one with the shortest life when it’s badly maintained. Cleaning frequency is the main lever.
How often
| Environment | Steam clean frequency |
|---|---|
| Low-traffic office (private offices) | Every 18–24 months |
| Standard open-plan office | Every 12 months |
| High-traffic office / call centre | Every 6–9 months |
| Reception and entry areas | Every 3–6 months |
| Retail | Every 3–6 months |
| Medical and education | Every 6 months |
Entry areas need far more frequent attention than the rest of the floor. The first four metres inside a door take the majority of the soil that enters a building. Treating them on a separate schedule is much cheaper than pulling the frequency up everywhere.
What determines carpet life
Vacuuming frequency. The single biggest factor, and the cheapest. Soil in carpet is abrasive, it cuts the fibre every time someone walks on it. Carpet that’s vacuumed thoroughly three times a week lasts substantially longer than carpet vacuumed once.
Edges and under desks. The areas that get skipped are where soil accumulates and where the wear eventually shows first.
Entry matting. Good matting captures most of the soil before it reaches the carpet. Cheap or undersized matting is a false economy.
Spot response time. A spill treated within an hour usually comes out. The same spill treated a week later often doesn’t.
Steam cleaning frequency. Removes the embedded soil that vacuuming can’t.
What it costs
| Method | Cost | Dry time |
|---|---|---|
| Hot water extraction (steam) | $4 – $8 per m² | 4–12 hours |
| Encapsulation | $3 – $6 per m² | 1–2 hours |
| Bonnet buffing | $2 – $4 per m² | 30–60 min |
Most commercial contracts specify a minimum charge, typically $250–$400.
Which method
Hot water extraction is the deep clean. It’s what carpet manufacturers specify, and often what warranties require. Longest dry time.
Encapsulation uses a polymer that crystallises around soil, which is then vacuumed out. Faster drying, less deep. Good as an interim between extractions.
Bonnet buffing cleans only the top of the pile. It’s a cosmetic refresh, not a clean, useful before a client visit, not a substitute for extraction.
A sensible programme: extraction annually, encapsulation at six months, bonnet as needed.
Warranty implications
Most commercial carpet warranties require documented professional cleaning at a specified interval, commonly every 12 to 18 months. Skip it and the warranty may not apply when you need it.
Keep the records. If your cleaning provider gives you a per-visit service record, periodic work should appear in it too, that’s your warranty evidence without hunting for old invoices.
What to do between cleans
- Vacuum edges and under desks weekly, not just open areas
- Treat spots within the hour, keep a spotting kit on site
- Blot, never rub, rubbing spreads and damages the pile
- Check and clean entry matting weekly, including underneath it
- Rotate or move furniture occasionally so wear spreads
The false economy
Cutting carpet cleaning to save money is a false economy that shows up on the capital budget rather than the operating one. Commercial carpet is $60–$150 per m² to replace. Cleaning it is $4–$8. A programme that adds three years to a carpet’s life pays for itself many times over, it just does it in a different line of the budget from the one it’s saved in.
