What's behind our decking Ratings?

Experts at our National Testing and Research Center tested 25 models in decking to see which ones perform best.

We look for:

Overall score
Overall score based mainly on resistance to color change, staining, slips, flexing, sagging, mildew after one year outdoors. Ratings of previously tested models may have changed due to changes in scores for resistance to flexing and sagging.Tests are with original finish; treating wood would improve its scores. Displayed scores rounded; models listed by precise overall score.
Resistance to slipping
Resistance to slipping is amount of friction for leather and neoprene under wet and dry conditions.
Resistance to flexing
Resistance to flexing is resistance to bending under load.
Resistance to sagging
Resistance to sagging is resistance to permanent bending from gravity over time.
Resistance to mildew

Decking buying guide

If your decking has cracks, looks dirty, or suffers from mildew, it's time to decide whether to refinish or replace it entirely. Signs of an unsafe deck are often less obvious but safety checks are critical when deciding to repair or replace. Also, if your deck was built before 2004, it's probably made of lumber treated with chromated copper arsenate. Regular refinishing helps to seal in the toxic arsenic that CCA decking contains. But if the finish is flaking or worn off in spots, we suggest hiring a pro who's equipped to safely remove the old finish, dust, and debris and then refinish it.
