Deciding whether to clean or replace your carpet depends on its condition and age. If cleaning no longer resolves issues, it's time to consider a replacement. Key signs that you need to replace your carpet include:

• Stains that are impossible to remove.

• A persistent smell that lingers even after cleaning.

• An increase in allergy symptoms.

• The age of the carpet. Most manufacturers state that carpets should last about 10 years with proper care.

When cleaning is no longer effective, you should replace the carpet with a new one or consider other flooring options like vinyl or laminate.

There are a couple of color options to consider when installing carpet in high-traffic areas (like entrances and stairways). Medium-toned colors and patterned carpets can work well in these parts of your home because dirt and stains can blend in easily. Dark carpets will also conceal marks and spills, but they show lint and other light-colored debris. Consider a medium brown or tan for your high-traffic areas. Either way, it’s best to avoid paler shades, like white and cream, which get dirty easily.

Stain-resistant carpet might be worth it for your household if you have children or pets and expect spills to happen. While it may cost more than you expected upfront, you may save money in the long run if you have to replace your carpet less frequently (thanks to stains not absorbing down into the fibers). 

Depending on carpet type and labor, costs range from $3 to $12 per square foot.
