Two different professional carpet cleaning methods compete for the same job. Steam cleaning—technically hot water extraction—and dry cleaning use different processes and produce different results. Understanding the differences helps you choose the right method for your specific carpet and situation. The two methods are not interchangeable.
A note on what we offer: Alexanian provides professional in-home carpet cleaning using hot water extraction (steam cleaning). We do not offer dry cleaning services — we recommend hot water extraction for residential carpet because it delivers the deeper, more thorough clean most homes need. The comparison below is here so you can make an informed choice about the method, whoever you hire.

The Short Answer
For almost all residential carpet, hot water extraction is the right method, and the six to twenty-four hours of drying is the price of it being the deeper clean. Dry cleaning earns its place in a narrower set of cases — a room that cannot be out of service, a basement or condo where moisture is a concern, and routine refreshes between the deep cleans.
Worth saying plainly, because it is unusual for a company to say it: we do not offer dry cleaning. If your situation is one of the ones where it is genuinely the better fit, look for an IICRC-certified provider that specialises in low-moisture work. We would rather point you there than sell you the method we happen to own.
And a naming point that causes more confusion than anything else on this page: steam cleaning does not use steam. It uses hot water under pressure, extracted immediately. The name stuck and nothing about the process matches it.
How Hot Water Extraction Works
Despite the common name, steam cleaning doesn’t actually use steam. Hot water at temperatures around 200 degrees Fahrenheit or higher, mixed with cleaning solution, gets injected into the carpet under pressure. Powerful vacuum suction immediately extracts the water, cleaning solution, and dissolved dirt before any of it can resettle into the carpet.
The result is deep-cleaned carpet that’s been thoroughly rinsed of cleaning chemicals and contaminants. This is the most common professional carpet cleaning method and the one most people associate with the term ‘professional carpet cleaning.’
How Dry Cleaning Works
Dry cleaning uses minimal moisture compared to hot water extraction. A dry compound or low-moisture solution gets applied to the carpet. Mechanical agitation through rotary brushes or pads works the cleaning agent into the fibres. The cleaning agent attracts and holds dirt, which then gets vacuumed away along with the agent itself.
The carpet is usable within an hour, much faster than the six to twenty-four hour drying time that hot water extraction requires.
The Two Methods Compared
| Hot water extraction (steam) | Dry cleaning | |
|---|---|---|
| Depth of clean | The deepest available — reaches embedded dirt, and removes more allergens, dust mites and contaminants | Less deep; a surface refresh rather than a restoration |
| Usable again | 6 to 24 hours of drying | Within about an hour |
| Best for | Heavily soiled carpet, set-in stains, allergen-heavy homes, homes with pets, and most annual or semi-annual residential cleaning | Routine cleaning between deep cleans, moisture-sensitive areas such as basements and condos, and rooms that cannot be out of service |
| Watch for | Mould risk if the carpet does not dry properly, and residue if the cleaner is not fully rinsed out | Residue from the cleaning agent itself, and weaker results on heavy soiling or set-in stains |
Which Method Fits Your Situation
The right choice follows what the carpet actually needs and not what happens to be on offer.
For heavily soiled carpet, set-in stains, allergen-heavy environments, and homes with pets, steam cleaning provides the deeper clean needed. The longer drying time is worth it for the thoroughness. For most annual or semi-annual residential cleaning, steam cleaning is the recommended method.
For routine quick cleaning between deeper steam cleanings, for moisture-sensitive areas (basements, condos with sound concerns), and for situations where carpet must be usable quickly, dry cleaning fills a specific need. It is also better for commercial offices and high-traffic spaces that cannot afford full drying time. Alexanian does not provide dry cleaning; if this is the right fit for your situation, look for an IICRC-certified provider that specialises in low-moisture methods.
Combining Both Methods
Different methods at different intervals can work well together; neither rules the other out. Annual deep hot water extraction handles the embedded dirt and oils that vacuuming and dry cleaning can’t reach. Quarterly or semi-annual dry cleaning between steam cleanings keeps high-use areas looking fresh without the drying-time inconvenience. Spot cleaning with appropriate products handles individual stains and spills as they happen.
How Carpet Cleaning Is Actually Quoted
Most pages on this subject price carpet cleaning by the square foot. We do not sell it that way. Carpet cleaning is quoted by the room — a job is booked as three rooms and a hall, not as nine hundred square feet — and a number written in a unit nobody quotes in is difficult to compare against anything.
- Carpet cleaning — by the room
- Upholstery — by the piece
- Tile and grout, and area rugs — by the square foot
- Extra work on a carpet — by the square foot, on top of the room price
- Every service — carries a minimum, so a single small room is rarely the economical booking
Which of the two methods costs more is the wrong axis to choose on, and it is the one most comparisons reach for because it is the easiest to tabulate. The two do different things to a carpet — depth of clean against speed of return to use — and the comparison earlier on this page is the decision that actually matters. Pick the method the carpet needs; the quote follows the method.
What moves the price is rarely the method. Stairs are usually quoted separately, because they are hand work and a stair is not a room. Furniture moving is included on our own cleaning visits, within what the technicians can safely shift, and it is worth asking of anyone else because some firms charge for it. Do not read that across to a flooring installation, where moving furniture is a separate line quoted against the job. Pet contamination adds pre-treatment and sometimes a separate odour treatment, and an area that has to be treated twice costs closer to double than to one and a half times. Ask for the quote broken down by room instead of as a single number, and it becomes possible to see what you are paying for.
Hot water extraction is what we do, and it suits most Ontario homes. Book in-home carpet steam cleaning and we will tell you if your case is the exception.
Getting the House Ready
Half an hour of preparation makes a measurable difference to the result, and most of it is obvious once someone says it.
- Vacuum thoroughly the day before. Extraction is for what is embedded; anything still loose on the surface just turns to slurry
- Clear the breakables yourself — lamps, picture frames, anything off a tabletop — and pick up toys, books and the small things off the floor
- Write down the problem spots and point them out on arrival — a stain someone knows the history of is a stain that gets the right treatment
- Leave the heavy furniture to the technicians. On an in-home clean we move what we can — small tables, chairs and the like. Beds, dressers and large wall units generally stay where they are, and we clean around them
- Have someone on site to let the technicians in and walk them through the rooms. We ask for this on every visit, because the problem areas are much easier to point at than to describe
- Plan the drying. Six to twenty-four hours after extraction, about an hour after a low-moisture clean
Drying time is the number people plan around and the one that varies most. A dense cut pile in a humid August room takes the long end of the range; a low-pile loop in a dry, well-ventilated house takes the short end. Airflow does more than anything else, which is why a cleaner who sets air movers running and asks you to leave the ceiling fans on is not padding the job. The floor should be dry through before furniture goes back, and putting a sofa leg onto damp carpet is how you get a rust mark that outlasts the cleaning.
How to Choose a Cleaner, Whichever Method You Pick
- IICRC certification — the industry training standard, and the easiest single filter
- Insurance, confirmed rather than assumed
- Recent reviews, on a platform the company does not control
- Ask which method they recommend for your carpet, and why. The answer tells you more than the certification does. A cleaner who explains the trade-off honestly wants the next job; one who recommends the highest-margin method regardless of the carpet in front of them does not
- Ask whether the technician is an employee. Ours are, so they can be trained, certified and background-checked as a matter of course. Our firm and our technicians are certified by the Institute of Inspection, Cleaning and Restoration Certification and by the Carpet and Rug Institute, every technician passes a background and motor vehicle check, and the company is insured
DIY vs Professional
Home carpet cleaning machines, whether rented or owned, use the same general principles as professional steam cleaning. The difference is in execution: home machines have lower water temperature, less suction power, and use general-purpose cleaning agents. Results are usually adequate for routine maintenance but less thorough than professional cleaning. Three cautions are worth more than any technique: avoid high-pH cleaning solutions, avoid excessive abrasive action, and on a stain-resistant yarn system do a general clean first and only then spot-clean what is still there, with an approved agent. Cationic treatments — the anti-static and anti-microbial products — should not go onto a stain-resistant carpet at all. Home cleaning also has higher risk of over-wetting because suction is weaker, which can cause mould if the carpet doesn’t dry quickly enough.
For routine cleaning, DIY can work. For annual deep cleaning, professional service typically produces noticeably better results that justify the cost difference.
What People Get Wrong
- “Cleaning carpet too often wears it out.” The opposite. Regular professional cleaning extends carpet life — it is the grit left in the fibre that does the wearing
- “Cleaning makes carpet get dirty faster.” Improper cleaning does, because leftover residue attracts soil. Properly rinsed carpet stays cleaner for longer
- “Steam cleaning shrinks carpet.” True of older natural-fibre carpet. Not true of modern carpet properly cleaned
- “The right cleaner gets any stain out.” Partly. Some set-in stains are permanent whatever the method, and a cleaner who tells you so in advance is doing you a favour
A Year-Round Rhythm
- Annually — professional steam cleaning, which works for most residential carpet
- Quarterly — dry cleaning between steam cleanings to keep high-use areas refreshed
- As it happens — prompt spot treatment for spills and accidents
- Either method — professional service produces better results than DIY in most cases
Carpet is one surface in a house full of them, and the intervals interlock — the whole-home care guide sets out how the rest of it fits around the annual carpet clean.

Frequently Asked Questions
Is steam cleaning or dry cleaning better for carpet?
Steam cleaning provides the deepest clean and is best for annual or semi-annual cleaning. Dry cleaning is faster (carpet usable within an hour) and better for routine maintenance between steam cleanings.
How long does steam cleaned carpet take to dry?
Typically 6 to 24 hours depending on humidity, ventilation, and carpet thickness. Running fans and HVAC during drying speeds the process.
Does steam cleaning damage carpet?
Properly performed steam cleaning does not damage modern carpet. Improper cleaning—over-wetting, residue from incomplete rinsing—can cause issues. Professional cleaners using proper methods produce safe results.
How often should I have my carpet professionally cleaned?
Most homes benefit from annual steam cleaning. Pet households or high-use homes benefit from semi-annual cleaning. Light-use rooms can extend to every 18 to 24 months.
