There are two installation styles for stair carpeting: waterfall and French cap. Waterfall is exactly how it sounds: the carpet is simply bent over each step and falls straight down to the tread on the next step. It’s a fast and easy form of installation and the one that most builders choose.

The French cap method takes longer and is a bit more complicated. The installer wraps the carpet around each step and tucks it under the lip, creating a more defined contour that many people prefer.

Durability

Given how much wear-and-tear the average stair tread endures, it’s important to choose a carpet fiber that can take it. Synthetic carpet fiber lasts longer than cotton or wool fibers. Nylon carpet fiber is more durable than olefin or polyester fiber. Stainmaster and Anso are two fiber types that hold up well on stairways.

Two main carpet construction types influence carpet durability. Bulked continuous filament (BCF) carpet is made in sections, with one continuous piece of fiber for each section. Major manufacturers of synthetic carpets favor this method because it offers more design options and is shed-resistant. Staple carpets weave together many short fiber lengths. It’s mainly used with natural carpet fibers, such as wool.

Protection against color fading is another factor to consider. Look for solution-dyed nylon fibers because they hold their color longer due to how the color penetrates the entire fiber. Of course, pay attention to cleaning instructions so you don’t accidentally fade your rug color by using the wrong kind of carpet cleaner.

Soil and Stain Resistance

You aren’t likely to have as many spills on the stairs as you would in a bedroom or living room. But soil and stain resistance are still important considerations when choosing your carpet. This is especially true if you’re a dog or cat parent who frequently deals with pet messes.
