I need to get my carpets professionally cleaned. What should I look for in a good carpet cleaning service?

A good carpet cleaning service should be more than just the cheapest quote. I’d look for these things:

• Certified technicians. IICRC certification is a useful credential because it covers carpet fibers, cleaning chemistry, equipment, inspection, and cleaning procedures. You can verify an IICRC-certified firm through the organization’s locator.IICRC+1
• A clear cleaning process. Ask whether they vacuum first, pre-treat/pre-spray heavily soiled areas, and thoroughly extract the cleaning solution. Pre-vacuuming and proper pre-treatment are important parts of professional cleaning.IICRC+1
• Experience with your particular carpet. The cleaner should ask about the carpet's fiber and condition rather than treating every carpet identically. This matters especially for wool, natural fibers, older carpets, or specialty rugs.
• Transparent pricing. Get the total price in writing and ask specifically about stairs, furniture moving, stain treatment, deodorizing, protectant, and other add-ons. Beware of an unusually low advertised price that turns into a much higher bill onsite.The Carpet and Rug Institute+1
• Good reviews and a track record. Look for a consistent pattern of recent reviews, particularly comments about actual cleaning results, punctuality, professionalism, and whether customers experienced surprise charges.
• Insurance and accountability. A legitimate company should be willing to explain its insurance coverage and provide an invoice/receipt.
• Realistic promises. Be cautious of anyone promising that every stain will disappear. Some stains permanently alter carpet fibers or dyes.
• Reasonable drying expectations. Ask how long the carpets should take to dry and what they do to minimize excess moisture. Over-wetting can contribute to problems such as soil wicking back to the surface.IICRC
• Carpet-warranty awareness. Check your carpet manufacturer's cleaning requirements before booking; some warranties specify particular cleaning methods or approved products. The Carpet and Rug Institute also maintains a Seal of Approval program for service providers.The Carpet and Rug Institute

Five questions I'd ask before booking

1. “Are your technicians IICRC certified?”
2. “What cleaning method do you use, and what does the process include?”
3. “Is vacuuming and pre-treatment included?”
4. “What is the total price, including stairs, furniture, and stain treatments?”
5. “How long should my carpets take to dry?”

One particularly useful test: if you call and the company can give you a very low price without asking anything about the size/condition of your carpet, that’s worth questioning. A good cleaner should want enough information to give you a meaningful estimate.The Carpet and Rug Institute+1

If you tell me what city you're in, I can also help you compare local carpet cleaners based on reviews, certifications, services, and pricing.

A good carpet cleaner is less about having the flashiest equipment and more about having a clear process, trained technicians, transparent pricing, and appropriate insurance.

What to look for

• IICRC-trained technicians. The Institute of Inspection, Cleaning and Restoration Certification (IICRC) is a useful industry credential. Ask whether the actual technician coming to your home is certified—not just whether the company has someone certified.The Carpet and Rug Institute+1
• A pre-inspection. They should ask about the carpet's fiber, age, stains, traffic, and any manufacturer-care requirements before deciding how to clean it. Different fibers can require different approaches.IICRC
• A clearly explained cleaning method. Hot-water extraction is one of the most common professional residential methods, but a reputable cleaner should explain why its chosen method is appropriate for your carpet rather than simply saying "we steam clean."The Carpet and Rug Institute
• Thorough pre-vacuuming and pre-treatment. Professional cleaning should involve removing dry soil first and treating soils/stains before extraction.Angi
• A written, itemized quote. Make sure it specifies what's included and separates things such as stairs, heavy stain treatment, pet-urine treatment, furniture moving, and carpet protector. This is one of the best ways to avoid a cheap advertised price turning into a much higher bill.The Carpet and Rug Institute+1
• Liability insurance and workers' compensation. Ask for proof rather than simply taking "we're insured" at face value.Angi
• Realistic claims. Be wary of anyone promising that every old stain or pet odor will disappear. Some stains or contamination can be permanent or require more extensive treatment.
• A drying plan. Ask how long they expect the carpet to take to dry and what they'll do to minimize moisture. Excessive moisture can create problems, so good extraction and appropriate drying matter.J+J Flooring Group
• Recent, detailed reviews. Look for reviews that specifically mention the quality of the cleaning, punctuality, pricing, and whether stains actually improved—not just five-star ratings with no detail.

Questions I'd ask before booking

"Are your technicians IICRC certified?" "What method will you use on my particular carpet, and why?" "Does the price include pre-treatment, spot treatment, and extraction?" "Are there any additional charges for stairs, furniture, or pet stains?" "Can you give me the complete price in writing?" "How long should it take to dry?" "Are you insured, and can you provide proof?" "What happens if a stain reappears after cleaning?" One red flag: an extremely low "whole house" price that isn't accompanied by a precise explanation of what's included. The Carpet & Rug Institute specifically recommends getting the pricing structure and expected cost clarified before the cleaner arrives.The Carpet and Rug Institute

If you're in the Detroit/Metro Detroit area, I can also look up several local carpet cleaners and compare their reviews, pricing transparency, cleaning methods, certifications, and services for you.

A good carpet cleaning service should be transparent, properly trained, insured, and focused on the condition of your particular carpet—not just the cheapest advertised price.

What to look for

• IICRC-certified technicians. The Institute of Inspection Cleaning and Restoration Certification (IICRC) is a major industry certification body. You can verify certified firms through its directory.IICRC+1
• A clear, written quote. It should specify what areas are being cleaned, the price, and any extras such as heavy-stain treatment, deodorizing, furniture moving, or carpet protection. Be cautious of an unusually cheap advertised price that turns into a much higher bill.Carpet and Rug Institute+1
• The right cleaning method for your carpet. Hot-water extraction (often called “steam cleaning”) is a common professional deep-cleaning method, but the best approach depends on the carpet fiber, condition, and manufacturer requirements.Carpet and Rug Institute+1
• Proper pre-cleaning. Ask whether they thoroughly vacuum/remove dry soil before applying cleaning solution. The Carpet and Rug Institute specifically recommends asking this.Carpet and Rug Institute
• Insurance. Confirm they carry appropriate liability coverage and, where applicable, workers' compensation. This matters if they damage your carpet, furniture, or property or someone is injured.Angi
• Good, consistent reviews. Look beyond the star rating—read recent reviews for comments about punctuality, hidden charges, stain removal, drying time, and how the company handled problems.
• Honest expectations. A reputable cleaner won't promise that every stain will disappear. Some stains and carpet damage are permanent.Better Business Bureau
• A satisfaction guarantee or callback policy. Find out what happens if stains return or you're unhappy with the result, and get the terms in writing.Better Business Bureau

Questions I'd ask before booking

1. “Are your technicians IICRC certified?”
2. “What cleaning method do you recommend for my carpet, and why?”
3. “Is the quoted price the total price, including pre-treatment and extraction?”
4. “Do you charge extra for stain treatment or moving furniture?”
5. “How long should the carpet take to dry?”
6. “Are you insured?”
7. “What happens if I'm not satisfied with the cleaning?”

One particularly useful tip: don't choose solely based on the lowest price. The Carpet and Rug Institute recommends comparing the actual services, pricing, experience, and qualifications of several companies.Carpet and Rug Institute
