These result in unpleasant odors and are laden with harmful bacteria that in turn can lead to more serious hazards and severe damage to the carpet, under padding and even the floor. Many of the same or similar but unseen and undetected contaminants can be tracked in by pets or under the shoe, unnoticed spills from the kitchen floor, tiny insects, etc. In brief, the sources seem limitless. Carpets properly cleaned can alleviate these concerns and perhaps in an indirect way even reduce medical costs. It stands to reason, the removal of contaminants reduces the chance of environmentally induced illness.
Clean carpets look better.
Sometimes the 'do it yourself' approach, though seemingly more economical, can prove to be more costly. A common problem with this approach is that often, not enough moisture is removed from the carpet. This can be due to lack of experience on the part of the person doing the cleaning, but can just as often be due to improperly maintained rental equipment. Call a professional and get the job done right. Frequently vacuumed and cleaned carpets last longer.
