Redwood Decking

Decking options have changed over the years and now many decks are built using composite lumber that has a longer life, does not require staining, and does not splinter. The higher price initially can make up the difference of maintenance cost in about 3 yrs. We recieved bids for the same deck plan using both Redwood and Trex (Trex seems to be the most popular brand of composite decking)
