How decking materials sold?

Decking boards and posts are priced according to linear foot calculation by different sizes or simply as a price per every foot for a particular product with certain dimensions. In our case all costs and decking prices were converted to approximate charges per square foot (sq. ft.).

- building concrete foundation for posts according to local codes
- installation of posts
- standard deck construction
- deck railing installation

What are the extra costs?

There are many factors which might increase the total cost of building a new deck. Area preparation for a new deck construction will result in additional charges. Building stairs or installation of custom made balustrades as well as incorporation of a few decking materials into a ustom build deck design cannot be calculated simply on per square foot basis. Cost for such work will be much higher in comparison with a simple standard construction. It is very common to use one type of material for building a structure of a deck and other for flooring and railing or balustrades. In such case cost will be prorated accordingly to prices for specific products used. Steel posts or metal frame deck construction might be estimated as much as 50% - 150% more expensive for labor and materials in comparison with a wood option.
