Most of our decks are built out of treated yellow pine, and some are made of untreated cedar or redwood. The biggest problem is that they require annual maintenance to keep them looking good and structurally strong. If you fall behind in properly sealing your deck every year, don’t use a good quality sealer, do a poor quality application, or don’t do anything, then your deck can rapidly deteriorate. You will experience cracking, splitting, warping and the growth of mold and mildew. So what do you do?

Deck Lumber Alternatives
1. You can take care of the deck with an annual cleaning, then painting with a good sealer.
2. You can save yourself all that money on cleaner and sealer and all that time in maintenance by choosing a no maintenance deck material.
All of the listed alternatives will offer you very attractive and durable decks or porches while eliminating the maintenance drudgeries and costs of typical decks. An annual cleaning and application of waterproofing will cost you at least 20 cents per square foot for the waterproofing material, deck cleaner, and painting supplies. It will cost you at least 80 additional cents per square foot for your hours of labor and the aggravation of going to the home center to buy the materials, then apply the deck cleaner, scrub it, wash it off, apply the waterproofer, and then clean up the whole mess. The no maintenance deck materials are initially more expensive than traditional treated yellow pine lumber, but they pay for themselves in a couple of years through avoided maintenance costs.
• Durability – last much longer than standard treated yellow pine lumber
• Maintenance – require almost none
• Economy – save on maintenance and replacement
• Aesthetics – often come in a variety of colors and patterns, often look exactly like regular lumber, and often fade to an attractive weathered grey
• Comfort – are slip resistant and do not give splinters
• The Environment – use recycled materials and won’t require landfill space in the future
Composite lumber: There are a number of 50-50 wood waste/recycled plastic lumber products which are very durable, and install just like regular lumber. They look very similar to regular wood and never require any maintenance.
Plastic lumber: There are 100 percent recycled plastic lumber manufacturers around the country. The products have a similar workability to wood. There are many uses for this material, although they may not be best suited for decks.
