We have been operating for over 20 years, and have successfully cleaned every conceivable type of carpet and furniture fabric you could imagine, this means it is unlikely we will encounter any problems when doing cleaning work for you.
This was true many years ago when carpets were cleaned with a rotary shampoo machine, and would leave a sticky residue in the carpet, we use warm water extraction, which will wash and leave your carpets clean and bright with no sticky residue.

No it will not affect her in any way, we use external extraction equipment, which stays outside , all of the damp air created by the cleaning process, is extracted to holding tanks in the van outside, this also speeds up the drying time, unlike the portable machines used by most other companies, which stay in the room where they're working.
