Questions to ask
1. Are you insured and bonded — what liability coverage do you carry, and do you have workers’ compensation if you send employees?
Why it matters: Carpet cleaning means heavy machines, wet floors, furniture moving, and access to every room. Ask for a certificate of insurance with general liability limits, whether bonding covers theft, and whether workers’ comp covers on-site injuries. A solo operator may structure coverage differently than a multi-tech company, but “I’ve never had a claim” is not a policy. Get carrier name and dates in writing before they roll a truck into your driveway.
2. What cleaning method will you use on my carpet — hot-water extraction, shampoo, encapsulation, dry compound, or something else — and why is that method right for my fiber and soil level?
Why it matters: Wool, nylon, olefin, and berber behave differently; so do pet urine, grease, and tracked-in dirt. Hot-water extraction (often called steam cleaning) is common for deep soil but needs proper rinse and extraction so the pad does not stay wet. Dry or low-moisture methods dry faster but may not lift heavy soil. Ask them to name the fiber if they can see or you know it, and to explain pre-spray, agitation, rinse, and extraction steps. A one-method-fits-all pitch is a sign they are selling a truck, not a cleaning plan.
3. Are your technicians IICRC-certified (or similarly trained), and will the person who quoted the job be the one who cleans — or a different tech or subcontractor?
Why it matters: IICRC (Institute of Inspection, Cleaning and Restoration Certification) training covers carpet cleaning, odor, and water damage standards many insurers and manufacturers reference. Ask for the technician’s certification type and whether it is current. Also ask who shows up: a polished estimator and an untrained day laborer is a common bait-and-switch. Prefer a named tech or small consistent crew over “whoever is free Saturday.”
4. Will you do a walk-through and give a written price by room or square footage before work starts — and what triggers extra charges?
Why it matters: Phone quotes based on “three bedrooms” hide stairs, hallways, stairs landings, closets, and heavy soil. Ask for a written scope: which rooms, approximate square footage, stairs, upholstery add-ons, pet-treatment rooms, and protector application. Clarify fees for excessive pet hair, grease, construction dust, after-hours, or same-day booking. The cheapest per-room rate often grows once “pre-spray” and “specialty stain” lines appear mid-job.
5. How do you treat pet urine, odors, and set-in stains — and what results can you honestly guarantee vs not?
Why it matters: Surface cleaning will not fix urine that reached the pad and subfloor. Ask whether they use enzyme or specialty urine treatments, whether they inspect with a UV light or moisture meter, and when they recommend pad replacement or subfloor sealing instead of another clean. Get any “stain removal guarantee” in writing with exclusions (bleach spots, dye loss, old pet urine, ink, rust). Vague “we’ll get it out or it’s free” claims that exclude everything meaningful are marketing, not protection.
6. Do you move furniture — what stays in place, what is your breakage policy, and do you put blocks or tabs under legs after cleaning?
Why it matters: Sofas, beds, and antiques are where damage claims start. Ask what they move vs what you must clear (breakables, electronics, lightweight tables), whether two people are scheduled for heavy pieces, and how they protect wet carpet from furniture stains (foil, blocks, or plastic tabs under legs). Photograph valuables and note existing scratches before they arrive. A crew that refuses to discuss furniture handling is planning to leave wet carpet under your sofa — a classic cause of permanent stains and odors.
7. How long until carpets are dry enough to walk on and replace furniture — and how do you avoid overwetting the pad?
Why it matters: Overwetting breeds odor, browning, and delamination. Ask about expected dry times (often several hours with good airflow; longer in humidity), whether they use truck-mounted heat and strong extraction, and what they recommend for fans, HVAC, or open windows. If someone promises “dry in under an hour” after a heavy hot-water clean in humid weather, ask how — or walk away. Slow dry times with no airflow plan are how “clean” carpets smell musty the next day.
8. Whose chemistry do you use — and can you accommodate kids, pets, allergies, or fragrance-free preferences without wrecking the clean?
Why it matters: Aggressive alkalinity, solvents, or heavy fragrance can irritate lungs and leave residue that attracts new dirt. Ask for product types (pre-spray, rinse, spotters), whether residue-free rinses are part of the process, and whether green or low-fragrance options cost extra. Confirm they will not use bleach or optical brighteners that can void carpet warranties or bleach spots permanently. If you have asthma or pets that lick floors, say so before they mix chemistry in your living room.
9. Is your equipment truck-mounted or portable — and is that a fit for my building (stairs, condo rules, parking, hose length)?
Why it matters: Truck-mounted units often heat and extract more powerfully; portables matter for high-rises, long walks from the truck, or buildings that ban driveway hoses. Ask about hose runs, water source, wastewater disposal, parking needs, and HOA or condo rules. A powerful truck that cannot legally park or reach your floor is useless. Conversely, a weak portable used on heavily soiled carpet may leave soil behind — get an honest fit for your access, not a sales preference.
10. What is your re-clean or satisfaction process if soil or spots return within a defined window — and how quickly do you come back?
Why it matters: Wicking (soil or stain rising back as the pad dries) is real; how they handle it is the test. Ask whether a free re-clean is offered within a set number of days, what counts as excluded (new spills, pet re-soiling, pre-existing dye loss), and how to report issues with photos. A company with no re-clean window and a shrug about browning is telling you who owns the risk after they cash the check.
11. Can you provide recent local references, and will payment go through a business invoice rather than large cash-only with no receipt?
Why it matters: References from homes with pets, kids, or similar carpet age beat star ratings alone. Ask for two recent clients, how long the company has operated locally, and preferred payment (card, check, invoice). Large cash-only demands with no written scope make refunds and damage disputes harder. Legitimate cleaners can usually take card or electronic payment and leave an invoice under their business name.
Red flags
- No liability insurance and refuses to show proof before the appointment.
- Per-room price far below every other bid with no walk-through — often a bait-and-switch on “pre-treatment” and “specialty stains.”
- Guarantees to remove all pet urine odor from pad and subfloor with a surface clean only.
- Cannot name the cleaning method, chemistry, or who will show up — or freely uses untrained day labor.
- Only cash, no written scope, no receipt, and pressure to “decide while we’re in the neighborhood.”
- Leaves carpets soaking with no drying plan; furniture put back on wet carpet with no blocks or tabs.
- No re-clean policy; blames “pre-existing” for every wicking or browning issue after the fact.
Next-step checklist
- Note fiber type if known, pet issues, problem rooms, and what furniture you can clear ahead of time.
- Get written proof of liability insurance (and bonding / workers’ comp if they have employees).
- Compare at least two written quotes with the same room list; note method, pet treatment, and extras.
- Confirm dry-time expectations, furniture moving rules, and any stain/odor guarantee exclusions in writing.
- Ask about IICRC (or equivalent) credentials and who will actually clean your home.
- After cleaning, check problem spots as carpets dry; use the re-clean window promptly if soil wicks back.
