Replacing your carpet depends on several factors, including its age, condition, and the level of wear and tear it has endured. Typically, carpets last between 5 to 15 years, with high-traffic areas showing signs of wear sooner. Consider replacing your carpet if you notice persistent stains, matting, or an increase in allergies, as these can indicate deeply embedded dirt and allergens. Additionally, if the carpet padding underneath is deteriorating, it can affect the overall comfort and support. Unpleasant odors that persist even after cleaning may also signal the need for a new carpet. Regular maintenance can extend a carpet's lifespan, but eventually, replacement becomes the best option for maintaining a fresh and healthy home environment.
