OPTIONS FOR ORDERS LARGER THAN 3,000 SQ FT:  

Factory Prestaining – we apply your choice of Sherwin Williams Oil-Based Superdeck Semi-Transparent stain colors or their clear sealer.  Additional charge is usually around $1.50 per sq ft. 

Factory Fire Treating – we apply Flame Stop II Class A topical treatment.  Additional charge is usually around $1.50 per sq ft.  If you need it Prestained as well it will require TWO coats of water based (cannot use oil based) stain making the total additional charge for Fire Treating plus Prestaining around $4.50 per sq ft.

OTHER GRADES:
Supreme Grade – we use a “nearly clear” grade board as the face piece to produce this decking.  Additional charge is around $2 per sq ft for Supreme Grade Southern Pine. 

OTHER SPECIES:
Need something other than Southern Pine?  We can use other species as the face piece to give you the look you are going for.  Main options include: Cypress, Doug Fir, Ponderosa Pine, and Western Red Cedar.  These are all available in both Decorative (Knotty) and Supreme (Nearly Clear) grades.  Contact us for pricing.  

DISCLAIMER:
*Note:  Span capabilities are affected by several factors such as roof slope, wind loads, and snow loads.  These differ from area to area and are governed by established building codes.  Always consult local building codes and/or an engineer to ensure that the decking you are using is the correct thickness for your project.
