what's wrong with pressure treated pine?
We've had a PT pine deck for 18 years, have it cleaned and retreated every other year (average $400 every other year, total $3600 maintenance over that 18 years). We are planning an addition and need to take down this old deck and build a new one. The contractor said that composite decking would be 4x the cost of PT pine. My original deck 18 years ago was $6400 cost. My maintenance costs are only 60 percent of the original cost of the deck over the lifespan. So why should I go for composite decking if I have been happy with the PT pine? It does get a little ratty by the 2nd year but the maintenance cleaning and upkeep seems to bring it back to life.
