All carpet cleaners come across a variety of indentations on carpets during their practice. On a newly installed carpets card board pole used to facilitate the transportation leaves pressure marks.   Professional carpet cleaners can remove these marks by a gentle application of steam which relaxes the pile. Subsequently, it can be groomed for complete unifying look. The most frequent pressure marks are left by heavy furniture. It may be because of cheaper underlay which breaks under the furniture weight.

Depending on the weight and the time duration furniture has sit on the carpet it may cause indentation not only to the carpet but also to the underlay. When the furniture has sit for too long the probability for the carpet to return its normal state is minimal. Even after professional carpet cleaning these marks remain noticeable as upon soil removal the fibres in the adjacent areas to the marks fluff up.

Your carpet cleaners can try to considerably wet the area, preferably with hot water and brush off. Allow the water to reach the underlay and the backing of the carpet in order to relieve compression. Traces from real heavy furniture may leave irretrievable indentations.
