Carpets quietly collect everything — dust, allergens, spills, and the grit tracked in on shoes. Vacuuming handles the surface, but deep-set dirt and odours need professional cleaning to actually leave. Here's how often carpets really need it, and exactly what to expect when the pros show up.
How often should you clean your carpets?
There's no single answer — it depends on traffic, who's in the space, and the environment. Use these as starting points:
- Average home: a professional deep clean every 12–18 months keeps carpets fresh and protected.
- Homes with pets, kids, or allergies: every 6–12 months — pets and little ones grind dirt and dander deep into the fibres.
- High-traffic commercial spaces (offices, lobbies, retail): every 3–6 months, more often for entrances and walkways.
- After a spill, flood, or illness: right away — the longer a stain or moisture sits, the harder it is to fully remove.
Many carpet manufacturers also require professional cleaning at set intervals to keep the warranty valid, so it's worth checking yours.
Vacuuming vs. deep cleaning — they're not the same
Regular vacuuming (ideally once or twice a week, more in busy areas) removes surface dirt and stops grit from cutting the fibres. But it can't reach the oils, allergens, and ground-in soil that settle at the base of the pile. That's what professional hot-water extraction — often called steam cleaning — is for: it flushes out the deep dirt vacuuming leaves behind.
What to expect during a professional cleaning
A proper carpet cleaning is a process, not just a machine passed over the floor:
- Inspection — we check the carpet type, traffic patterns, stains, and any problem areas.
- Vacuum & pre-treat — loose dirt is removed, and stains and high-traffic lanes get a pre-treatment to break down soil.
- Hot-water extraction — hot water and solution are injected into the pile and immediately extracted, pulling out dirt, allergens, and residue.
- Spot treatment — stubborn stains and odours are treated at the source.
- Groom & dry — the pile is groomed and airflow is set up to speed drying.
How long does it take to dry?
With professional extraction, most carpets are dry within 4–8 hours, depending on the fabric, humidity, and airflow. You can step on them sooner with care, but it's best to keep heavy traffic off until they're fully dry. Good airflow — fans, open windows, or AC — speeds things up.
Signs your carpet is overdue
- It looks flat, dull, or grey along walkways
- A faint musty or stale smell that vacuuming doesn't fix
- Allergy symptoms that feel worse indoors
- Visible stains or darkened high-traffic lanes
- It's simply been over a year (or over six months in a busy space)
Regular professional cleaning doesn't just look better — it removes allergens, controls odours, and genuinely extends the life of the carpet, protecting a big investment in your home or business.
Frequently asked questions
How often should carpets be professionally cleaned?
Most homes benefit from a deep clean every 12–18 months, every 6–12 months with pets, kids, or allergies, and every 3–6 months for high-traffic commercial spaces. Spills and floods should be handled right away.
Does professional carpet cleaning remove pet odours?
Yes — hot-water extraction with targeted treatment tackles pet stains and odours at the source rather than masking them. Deeply set-in odours may need a second pass.
How long until I can walk on the carpet?
Most carpets are dry in 4–8 hours depending on fabric, humidity, and airflow. Light foot traffic is usually fine sooner; keep heavy traffic off until it's fully dry.
