How often should you have your carpets cleaned?
Every cleaning company gives you a number of months. The number is not the useful part. What actually decides it is how much traffic the carpet takes and what comes in on people's feet.
Ask three companies and you will get three intervals, all presented as a standard. There is no standard, because the thing that wears a carpet out is not time. It is feet, and what those feet carry in. A spare bedroom nobody uses and a hallway between a front door and a kitchen are not on the same schedule and never were.
Traffic, not the calendar
Look at the carpet in the places people actually walk and compare it with a patch under a sofa or inside a closet. The difference you can see is not dirt sitting on top. The pile in the traffic lane has started to flatten and lose its twist, and the colour looks duller because light scatters off damaged fibre tips instead of reflecting cleanly.
When that contrast becomes obvious, the carpet is overdue. Once the traffic lanes have gone grey and stayed grey, cleaning will lift the soil but will not bring the appearance back, because the fibre itself is abraded.
What actually changes the answer
- Pets. Hair, dander, oil from coats, and the occasional accident. An accident needs treating on its own, not waiting for the next scheduled clean.
- Children, especially crawlers and toddlers, who put their hands and faces into the carpet and eat near it.
- Shoes on or off indoors. This is the biggest single variable in the list and it is free.
- A walk-out to a garden, a balcony or a deck. Soil, grit and lawn treatments come in on every trip.
- Toronto winters. Road salt and sand track in for months, and salt that dries in the pile keeps pulling moisture back.
- Allergies or asthma in the house. Carpet holds dust and dander, which helps only if it is being removed.
- A rental, where your tenants' habits are not your habits.
Grit is the argument that matters
Here is the part that turns this from cosmetics into maintenance. Most of what is in a carpet is dry soil, and a good share of that is mineral: sand, road grit, ground-up concrete dust. Those particles are hard and they have sharp edges. They sift down through the pile and collect at the base, near the backing, which is exactly where a vacuum cannot reach them.
Every footstep presses the fibre down onto those edges and drags it across them, which is abrasion rather than dirt, and it happens whether the carpet looks clean or not. Fibre that has been cut does not recover, and it shows as permanent greying and matting in the traffic lanes. Cleaning on a sensible interval removes the abrasive before it does that work. You are not buying a nicer looking carpet. You are buying the years at the end of its life. It is also why the hall and the stairs can justify a clean while the bedrooms do not need one yet.
Vacuuming is a different job, not a smaller one
Vacuuming removes loose surface soil and it should happen often, slowly, with several passes in the high traffic areas and a bag or bin emptied before it is full. A slow pass lifts considerably more than a fast one, and most people move the machine too quickly.
What vacuuming does not do is remove what has reached the backing, or the oily film that builds up from cooking, skin and outdoor air and binds fine soil to the fibre. That film is why a carpet can look dull immediately after vacuuming. Hot water extraction is what deals with both: the pile is flushed with solution under pressure and the water is pulled back out with the soil suspended in it.
Rentals, warranties and what it costs
If you let a property, treat carpet extraction as part of the turnover rather than an optional extra, in the same breath as the paint. It is cheaper than replacement and it is the difference between a carpet lasting several tenancies and lasting one.
Check your carpet paperwork too. Many manufacturers make periodic professional cleaning a condition of the warranty, and some ask you to keep the receipts. The required method, the interval and the term vary by manufacturer, so read the documents that came with your carpet rather than taking a figure from a cleaning company, including this one.
On cost, a small to medium room runs $40 to $60, or $0.25 to $0.50 a square foot, with a minimum service fee of $100 to $150. That minimum is why it pays to do several rooms in one visit rather than one room at a time. A full house of three to five rooms runs $200 to $1,000 and up, by size and condition.
