A professional tile and stone cleaning service can save you a lot of time and energy.  Professional tile cleaners use high pressure steam combined with the proper cleaning agents to emulsify and extract the contaminates from your tile surface and deep within the pores of your grout.  For a DIY homeowner to clean their tile and grout manually would take a lot more time and energy to accomplish the same task. 

Additionally with the use of a steam cleaning extraction system professional tile and grout cleaning contractors are able to sanitize your tile and grout and they are also able to more effectively rinse all remaining contaminates and excess cleaning agents from your tile and and deep within the pores of your grout.

All professional tile and grout cleaning contractors should be IICRC Certified for hard surface cleaning.  You should make sure that the contractor is fully licensed, bonded and insured.  Every state has different procedures for contractors to be licensed so it is best just to ask your prospective contractors to show you their valid contractors license.  Hiring a licensed, bonded and insured contractor will help insure you that should some unforeseen disaster happen while they are working inside your home that you will be fully insured.

Check the Better Business Bureau at BBB.org.  There you can search for prospective contractors and insure that there are no complaints filed against your prospective contractor.

Make sure that the contractor will come out to talk to you and give you a firm estimate before starting the work.  There are too many bait and switch contractors out there who make any excuse not to give you an estimate before beginning the work.  A quality contractor will come out to your home or business and talk to you about your prospective cleaning or restoration project.  The contractor should also do a test cleaning on your tile and grout so you can see what type of cleaning results can be obtained during their cleaning.  If necessary the contractor can explain other cleaning and sealing options such as regrouting or colorsealing for your particular tile and grout.
