Wood is the most common material for decks.
Spindle prices vary widely depending on the type of material used. Wood is generally the least expensive option. Wrought iron is the most expensive. The cost to clean and stain a wood deck, complete with rails and spindles (including power washing, labor, and materials) averages roughly $2 per square foot.
Costs vary greatly by region (and even by zip code). To get free estimates from local contractors, please indicate yours.
