If you’re looking to reduce carpet installation costs, there are several ways to save. Start by considering your carpeting needs. Manufactured materials such as polyester and nylon will be cheaper than natural fibers such as wool. From big box retailers, starting prices for olefin-based carpet are approximately 50 cents per square foot — making the cost under $5 per square yard. Indoor carpets made with olefin fibers are typically the least expensive on the market. Keep in mind that olefin fibers are not as soft on bare feet as other fibers, so are often used in areas like basements, playrooms or indoor patios. Nylon and polyester are good options to reduce carpet installation costs while still creating a cozy feel. The face weight, fiber construction and density of a carpet all affect the cost per square foot. The cheapest nylon or polyester carpets can start at just under $2 per square foot, making them about $18 per square yard. Lower-cost carpet tends to wear out more quickly and show stains more easily, so avoid light colors and vacuum regularly to keep the fibers clear of dirt that might age it too quickly.
