Carpet installation costs $2 to $8 per square foot to replace, depending on the quality, room size, and prep work. Replacing carpet in a 10x12 room costs $200 to $900. The cost to carpet stairs is $150 to $600. New carpet prices are $1 to $5 per square foot, plus $0.50 to $1.50 per square foot for labor.

Installing carpet takes 4 to 8 hours for an average room. In some cases, preparation adds another day for moving furniture, removing the old carpeting, removing the baseboards, and repairing the sub-floor.

Carpet should be replaced every 5 to 15 years. Replace carpet when it starts to shed, unravel at the seams, if there's water damage, or when there are stains, matting, or it smells bad.

Carpet lasts 5 to 20 years, depending on carpet and padding quality, material, foot traffic, and maintenance frequency. Carpets with a face weight (or fiber density) of less than 30 oz. last less than 7 years. A 40 oz.+ face weight carpet lasts 12+ years.

Flooring and carpet companies, handymen, and home improvement stores such as Home Depot and Lowe's install carpet in your area.

Most carpet installers will move your furniture as part of the installation or replacement. Some carpet installers charge $25 to $75 per room to move or rearrange large furniture or appliances.

Carpet installers do not expect a tip. However, if the company does a great job or spends more time than expected, most homeowners tip $10 to $40 per worker tip is appreciated.
