Cortex screws go in easy and look greatbut are time consuming to remove.   I personally Like the grove and vertical clip system of  Trex Transcends decking.

For the upcoming year of 2009,  building a deck in Oakland County Michigan May be considered a luxury to some, or and necessity for others.  Like everything else in  world “decks are on sale”.  And 400 square foot deck built in Oakland, Macomb, Livingston, or Washtenaw county will cost  $7500 for cedar, $10000.00 for composite (Trex), and $12,000.00 for PVC materials.   These prices are down 15% from 4-5 years ago while the price of materials and expenses have increased  10- 20 %  in recent years.  Great deal time to buy?
