What are some types of exterior staircases?

Exterior staircases can be constructed of stone, concrete, metal or wood. The homeowner's budget and the maintenance needed for the staircase should be taken into consideration when choosing the materials.

Stone, concrete and metal staircases can be expensive to build, but they are the most durable options and require the least maintenance, since cleaning requires just a spray with a garden hose. Exterior staircases constructed of wood or treated lumber are more affordable than other types of stairs, but they require staining or painting on a regular basis. Performing this maintenance ensures that the wood is free of rot and pests that can weaken the structure, making it unsafe to use.
