The Green Shield Difference

Green Shield only builds with ASTM D7032 compliant deck boards. Our deck boards have been carefully tested to not just meet but exceed ASTM D7032. This means a Green Shield deck board is built to withstand temperature swings, moisture, freeze-thaw cycles, and biodeterioration including fungal and termite damage. Our confidence in the Green Shield deck board allows us to offer a lifetime warranty on every deck. Touch and feel the difference of a Green Shield deck during your Deck Designer appointment. Free deck designs and deck estimates are available year round, even in winter.

"At Green Shield meeting and exceeding compliance standards is backed into every deck material our crews build with."
