Are you looking to get your tile and grout cleaned ? Here are the questions you should be asking at the time of your estimate.
1. Do you guarantee the tile and grout will look brand new when completed or will some stains not come out ?
2. Do you seal the grout ? Is there a guarantee on the seal ?
3. Are you the owner of the company or who is he and where is he located ?
4.Who will be doing the work ?
5. Is any damage or risks possible like grout coming out? Can you resolve them in the event that happens ?
