It’s a good idea to install a rug pad under the carpet for your stairs. To make the pad fit, you’ll need to cut one section for each stair tread that’s about one inch narrower than the stair runner so that it won’t be visible once the carpet is installed on top.

Nylon carpet is widely considered one of the most durable and longest-lasting options, typically lasting 12 to 15 years. Its durability comes from its high resistance to wear, tear, stains, fading, and abrasions. It also resists liquid spills, insects, mold, and mildew, making it ideal for high-traffic areas like living rooms and hallways. For even greater longevity, frieze or Berber carpets are excellent choices that can last up to 20 to 25 years.

Beyond the material, a carpet's construction is key to its durability. Low-pile carpets with short, tight loops hold up better against wear than high-pile options. As a synthetic material, nylon is available in a vast range of colors and styles and often feels remarkably soft.

Installing carpet over carpet may negatively impact the resale value of your home. While it offers a quick fix, potential buyers may view it as a temporary solution rather than a long-term investment in quality flooring. Properly installed and maintained flooring adds value to a home, so removing the existing carpet and installing new flooring may be a better option to attract prospective buyers and maximize resale value.

You can save money on labor costs by removing your old carpet before the professionals come in to install the new carpet. Just make sure to clear it with your contractor ahead of time. You might also be able to cut costs by buying carpet at certain times of year when it’s less expensive. These periods include late December to mid-January and late spring to early summer.
