Regular cleaning of your carpeting, rugs and upholstery is good maintenance. If that maintenance has not been performed as recommended by manufacturers they may be able to be restored rather than replaced.
Avoid Replacement Costs
Generally speaking, wall to wall carpeting should be vacuumed weekly and professionally cleaned once a year to maintain the carpet and maximize its useful life.
Sometimes carpet is not properly maintained and requires restoration due to heavy soiling. Not all carpets can be restored but it is usually worth the effort before spending the money to replace them.
