Although dependent on the type and size of lumber, most 2-by-4-by-8-foot pieces of lumber cost anywhere from $3 to $6. Softwood lumber like pine falls on the lower end of the spectrum, while hardwood lumber like oak or walnut falls on the higher end. Different retailers and lumber yards can also vary in price, so it helps to shop around to compare prices.

Most building codes require that railing spindles (also known as balusters) on decks or stairs be spaced no more than four inches apart. This safety standard is often called the '4-inch sphere rule,' which means a sphere with a 4-inch diameter should not be able to pass through the opening between balusters. This rule is in place to prevent small children and pets from slipping through the railing. For the same reason, the space between the bottom rail and the deck or floor surface should also be no more than four inches. As a general guideline, professionals often install three balusters per foot of railing. However, since specific requirements can vary by location, it is essential to check your local building codes to ensure compliance before starting your project.

If the stairs are already covered in carpet, you will need to remove the old carpet and possibly the carpet pad. Any damage to the stairs like cracks, loose boards, or creaky treads may also need to be repaired. You may also want to sand and refinish or paint wood stairs before installing a carpet runner.

The standard dimensions for a stair's rise (vertical height) and run (tread depth) depend on whether it is in a residential or commercial building. For residential buildings, the International Residential Code (IRC) and International Building Code (IBC) specify a maximum riser height of 7 3/4 inches (with a minimum of 4 inches) and a minimum tread depth of 10 inches. Additionally, the maximum total rise of a staircase should not exceed 12 feet between landings. For fixed stairs in commercial buildings, OSHA requires a rise between 6 and 7.5 inches and a run between 10 and 14 inches. Standards for other types, such as spiral staircases, will differ.
