It's generally recommended to have your carpets professionally cleaned every 12 to 18 months, depending on the amount of foot traffic, the presence of pets, children, or allergies, and the manufacturer's recommendations to maintain the warranty.

Professional cleaning can extend the life of your carpet by removing deep-seated dirt and debris that regular vacuuming cannot. It also helps to remove stains, improve indoor air quality by reducing allergens, and rejuvenate the overall appearance of your carpet.

The most common method used by professionals is hot water extraction, often referred to as steam cleaning. This method involves injecting hot water and cleaning agents into the carpet fibers and then extracting the water along with dirt and stains. Other methods include dry cleaning and encapsulation.

While many stains can be significantly reduced or removed entirely, the success rate depends on the type of stain, how long it has been on the carpet, and the carpet’s material. Professional cleaners have specialized techniques and products that improve the chances of removing tough stains.

Drying times can vary based on the cleaning method used, the type of carpet, and environmental conditions like humidity and temperature. Typically, carpets cleaned using hot water extraction can take anywhere from 6 to 24 hours to dry completely. However, using fans, dehumidifiers, or air conditioning can speed up the drying process.

Yes, it is safe when done by a reputable service. Professional carpet cleaners typically use cleaning solutions that are non-toxic and safe for families and pets. However, it's a good practice to discuss any specific health concerns with the service provider before the cleaning.

Remove small items and breakables from the rooms to be cleaned, vacuum the carpet to remove loose dirt, and move any light furniture if possible. Also, make sure there's a clear path for the cleaning equipment. Some services might ask you to secure pets and provide access to water or power outlets.
