Factors that affect the cost

You cannot expect a one-price-fits-all approach when getting a staircase built as there are a lot of variables that can affect the overall price of the job. These include the location of the staircase, its type, materials required, necessary balustrading, and the amount of work involved.


Is it going to be an interior or exterior staircase? The location of the staircase matters as interior and exterior staircases differ in materials, length, width, and price. Interior staircases have subtypes: main stairs, attic stairs, and basement stairs. Among those three, the main staircase is the most expensive and attic stairs are the most affordable.

Exterior stairs vary greatly in length, width, and height. For example, there are verandah stairs that run the whole length of the verandah, and there are stairs that are only a quarter of the area. Another are stairs for decks which vary in height depending on how high the deck is raised.


There are different types of staircases to choose from. They vary in design and complexity, so expect that their prices differ as well. Here are some of the most common types of staircases:

  • Straight – This is the easiest to design and build as it has no turns or bends; the stairs run from one floor to another.
  • Quarter Landing – This type is designed to have a landing and a safe 90-degree turn.
  • Half landing – This also has a landing, but the turn is a complete 180 degrees.
  • Winder Winder stairs are same as quarter landings and half landings as they can also have 90-degree or 180-degree turns. The only difference is that winder stairs do not have a landing.
  • Curved – Elegant and aesthetically pleasing, curved stairs gently curve from one floor to another.
  • Spiral – Spiral staircases use a central pole from which the steps protrude.
  • Floating – Floating stairs are perfect for modern homes. The steps are securely anchored to the wall so there is no visible support underneath.

There are three common materials that are used for stairs: wood, concrete, and metal. All three can be used indoors and outdoors and are durable.


Installing balustrading is a must to ensure safety, although some staircase designs do away with it. Three materials quickly come to mind when talking about railings: wood, metal, and glass. Of the three, metal and glass cost more.

Businesses also take into consideration the amount of labour. If it’s a replacement job, then they’ll need to factor in the demolition of the existing stairs. Preparation and finishes are price determinants too.

Stairs and staircases should always be safe for use, so it’s best to have a professional build one for you. Check out the top staircase builders on!
