The BBB offers a few tips before getting your carpet cleaned:
Ask friends and neighbours about carpet cleaning companies they would recommend.
Obtain references from family and friends, or request references from the company. A reputable cleaning professional should have available a list of satisfied clients or businesses that use their services. Also, check the company out with the Better Business Bureau.
If your carpet is new, read the warranty or ask the seller if there are any special cleaning methods recommended by the manufacturer. Some carpets must be professionally cleaned on a regular basis to maintain their warranty.
Know what you want done, and refuse to be pressured into purchasing services you do not want or need.
Obtain estimates from at least three different firms who are licensed and bonded.
Be wary of extremely low advertised prices that seem too good to be true. Refuse to do business with a firm that uses bait and switch tactics. In this practice, a company will entice you with a low priced service, only to play down the original offer and then recommend a totally different service, usually at a more expensive price.
Ask about extras that may increase the cost of the job. Find out what's included in the basic services offered. What constitutes an extra charge? What are the prices for each?
Before the work is completed, get a detailed, written contract from the company, specifying what areas will be cleaned. Ask if halls and closets are considered part of a room.
Find out what care is required after the cleaning. How long will it take to dry? What kind of ventilation is needed? These important questions should be asked BEFORE the cleaning takes place.
Whether it is dry foam, powders or shampoos, all products have a pH factor which is generally measured on a scale of one to 14. The cleaner's pH factor should be higher than seven, but anything over 10 may affect delicate colours. Ask the company to test the cleaning method on an unseen section of carpet before starting work.
Protective carpet treatments are beneficial but will not eliminate dirt and spills from spoiling your carpet.
