jan 3, 2019 but, generally speaking, wpc and pl decks don't require the annual makeover that wood decks do, and most last for decades with little more work than soap and water rinses. expect to pay around $3 per linear foot for 1 x 6 decking material, which puts it somewhere between the cost of western red cedar 【Get Price】

the 9 golden rules of a professional composite decking installation

upm profi deck should not be installed on open joists on first floor or higher levels. 4. the support rails/joists should be fixed to the ground or constructed to form an inter locking grid. this prevents thermal expansion of the deck boards distorting the design of the deck. 5. the maximum spacing between support rails / timber 【Get Price】
