Recent Composite Decking Installation in Rockville

A deck built to last

Product: Fiberon Concordia
Type: 4-Sided Composite Decking Board
Color: Castle Gray
Structural Warranty: Limited Lifetime
Stain & Fade Warranty: 50yr

When we first met with these clients their main concern was building a deck that will last as they planned to be in this home a lifetime. A good deck and even the longest lasting decking board is only as good as the treated lumber it is built on. With that in mind they elected to do above grade sonotubes rather than in ground posts as well as .23 MCA treated lumber. This strong foundation with along with decking joist tape ensures that this structure is here to last just as long as the decking board itself!
