The best way to choose a carpet cleaner is to ask a short list of specific questions before you book, because the answers separate a professional operation from a cheap one far more reliably than the advertised price does. The questions worth asking come down to four things: independent certification, trained technicians, transparent all-inclusive pricing, and a defined cleaning process. A genuine professional answers all four clearly and without hesitation. A budget operator using hire equipment and casual labour will struggle with at least one. This guide is the checklist we would use ourselves, and yes, it naturally describes how we work, because these are the standards we hold ourselves to.
The questions to ask before you book
1. Are your technicians trained or certified?
This is the single most telling question. Carpet cleaning done wrong, over-wetting, the wrong chemistry on wool, heat on a protein stain, causes damage that costs more than the clean. The recognised global standard for technician training is IICRC certification. A professional will be able to tell you how their technicians are trained. Our technicians are academy-certified through the Carpet Guys Academy and our work is aligned with WoolSafe standards, vague answers like "my guys are very experienced" with no training to point to is a flag.
2. For wool or natural-fibre work, is your chemistry WoolSafe-approved?
Wool, silk, and natural fibres are pH-sensitive and easily damaged by the alkaline products used on synthetics. The WoolSafe Organisation independently certifies cleaning products as safe for wool and natural fibres, and has done since 1991. If you have any wool carpet or rug, ask whether the cleaner uses WoolSafe-approved chemistry and tests for dye-fastness. A cleaner who treats wool like synthetic carpet will eventually ruin a wool piece.
3. What is included in the quoted price?
This is where most of the real cost difference hides. A low per-square-metre headline rate often covers only a single extraction pass, with stain treatment, urine treatment, deodorising, and a call-out fee all added at the end, so the final bill is far higher than advertised. Ask directly: does the price include all treatments, or is it basic extraction with extras? Our pricing is all-inclusive, every treatment built in, no call-out fee, no end-of-job add-ons, which we explain in full in carpet cleaning prices in Johannesburg.
4. What equipment do you use, and does it carry the CRI Seal of Approval?
Commercial extraction equipment is what makes a deep clean possible and a same-day dry achievable. The CRI Seal of Approval programme independently tests cleaning products and extraction equipment for performance. A cleaner using a domestic hire machine cannot match commercial extraction, and the result, slow drying, residue, rapid re-soiling, shows up within weeks. See professional cleaning versus a hire machine.
5. Do you assess the fibre and test before cleaning?
A professional identifies the fibre and tests delicate carpets and rugs for dye-fastness before applying any chemistry. This is non-negotiable on anything wool, silk, or uncertain. A cleaner who starts spraying without checking what your carpet is made of is gambling with it.
6. What is the dry time?
A professional clean with proper extraction dries in 2 to 6 hours. An answer of "a day or so" signals over-wetting and weak extraction, the cause of musty smells and re-soiling. See how long carpet takes to dry.
7. Are you honest about what cannot be removed?
A cleaner who promises to remove every stain is overselling. Sun fade, bleach marks, fibre oxidation, and some set-in stains are permanent, and a professional tells you that up front, see removing set-in stains. Honesty about limitations is a sign of expertise, not weakness.
Red flags to walk away from
- A price that seems too good to be true. A very low per-square-metre rate almost always means extras are added later, or corners are cut. The cheapest quote frequently becomes the most expensive bill.
- No fixed business details. No proper contact details, no reviews, no traceable business, cash only and gone tomorrow if something goes wrong.
- Pressure selling and "today only" discounts. A confident professional does not need to rush you.
- Vague or evasive answers to the questions above, especially about training, chemistry, and what is included.
- Promises to remove every stain regardless of age or type, no one can honestly guarantee that.
- A long dry time treated as normal, a sign of over-wetting and poor equipment.
- The same method for everything, a cleaner who treats a wool rug exactly like a synthetic carpet does not understand fibres.
Beyond the questions: do your homework
- Read genuine reviews on Google and independent platforms, and look for how the cleaner responds to any negative ones.
- Check the work matches the claim, a real process, real before-and-after work, real team, rather than stock imagery and slogans.
- Confirm a written quote, so the price you are told is the price you pay.
- Ask about insurance for the rare event that something goes wrong in your home.
How we measure up to this list
We wrote this checklist because it is the one we hold ourselves to. Our technicians are academy-certified and our work is WoolSafe-aligned; our chemistry is pH-appropriate and dye-tested on delicate fibres; our pricing is all-inclusive with no call-out fee and no add-ons; we follow a defined 7-step process; our carpets dry the same day; every rug is cleaned by hand; and we tell you honestly what can and cannot be removed before we start. You should expect every one of these from any cleaner you hire, not just from us.
Common questions
What is the most important question to ask a carpet cleaner?
How their technicians are trained, and what is included in the price. Training predicts whether your carpet is safe; inclusions predict whether the quote is honest.
Is the cheapest carpet cleaner ever the right choice?
Rarely for a deep clean. A low headline rate usually means extras added later or corners cut, and the risk of damage or rapid re-soiling is higher. For a light freshen-up of a synthetic carpet, a careful DIY clean can be fine, see professional versus hiring a machine.
How do I know if a cleaner is qualified to clean wool or Persian rugs?
Ask whether they use WoolSafe-approved chemistry, test for dye-fastness, and clean rugs by hand. If the answer is "the same as any carpet," choose someone else.
