Carpeting is probably one of the most expensive investments you will make as a homeowner and maintaining it is crucial. It can also be a breeding ground for tiny little creatures and retains quite a bit of contamination that does not come out with ordinary vacuuming. So it is inevitable that you will one day have to have it cleaned. Choosing a carpet cleaning company or cleaning it yourself is not as simple as it seems. Many companies offering low prices for carpet and upholstery cleaning, do so with the intent to sell you more. Their basic cleaning may consist of just using your hot tap water! Some use the warm water from your sink and portable equipment (no more powerful than the kind you rent). Additionally, they will offer you some "extras" like pre-conditioning of soiled areas, deodorizing and so on. Some have "Travel Charges" or "Service Charges." Most have usually higher minimums than the special advertised! If they say "3 Rooms $99", their minimum may be $132. Well, that fourth room/area may be double and then with the other "fees/charges" your cheap carpet cleaning, is not so cheap anymore. What about the person/s actually undertaking the work? Is it an owner or someone looking for a commission on what "extras" they sell you? Make sure to read the fine print on advertised specials, find out what type of cleaning system is being used and who is completing the actual cleaning!
