The durability and longevity of your carpet greatly relies upon whether you care for it and maintain it properly. If you care for your carpets, then they would be able to retain their color, texture, and smoothness for a much longer time. And if you follow the maintenance requirements for your carpets carefully, they can last for as long as 10-15 years.
So your carpets are not easily damaged through everyday exposure to different elements, make sure that you do preventive maintenance measures. For example, when entering your carpeted bedroom, make it a point to remove your shoes so that you don't drag in soil and other dirt from outside. If a specific carpeted room is exposed to sunlight all the time, install curtains or blinds so that the UV rays would not cause your carpet to age and discolor. Rearranging your furniture every so often would also help in keeping your carpet last longer especially if it is not very resistant to crushing. Remember that heavy and bulky objects like your furniture can crush your carpet and cause the fibers to limp out, so moving them and rearranging them often would help in prolonging the texture and softness of your carpet.
You can also do DIY cleaning to remove surface dirt from your carpet. If possible, vacuum your carpet everyday so that soil, grit, ashes and other types of dirt don't accumulate. As for stains and deep seated dirt, it would be best if you hire the services of a professional contractor for carpet cleaning Rock Hill SC. Don't attempt washing your carpet on your own if you don't have any knowledge on proper carpet cleaning. Keep in mind that if you damage your carpet due to use of improper cleaning solutions and detergents, you would no longer be able to claim warranty from your carpet provider. It would be best if you let the professionals do the cleaning instead since they know the proper carpet cleaning methods and techniques to use.
