Cedar and redwood are in demand selection for deck lumber, although they are becoming limited and less common because of their high price tags.

Man-made deck boards are highly-priced, yet require no maintenance or deck stain, and are resistant to weathering, making it worth the investment. You can use standard framing lumber, but it may require additional expenses and time for the frequent treatments, waterproofing, and staining that is required.

To build the deck to the home, a ledger board should initially be installed on the part of the home. It’s imperative to not get rid of siding since this can trigger water leakage. A level surface is essential when using cedar shims that aids accomplish this.

Then the box is sustained by posts, typically 4X4 pressure-treated lumber that aids resist insects and moisture. These support posts are spaced 8-feet or even less. An 8X8 foot deck, for example, would have two posts: one on each exterior corner, while a 16X16 foot deck needs six posts; five surrounding the perimeter which is spaced 8-feet apart then an additional at the middle later on. Perimeter posts should be installed initially, and then joined to footings. Any posts that fall at the platform’s middle are not built until the framing box is completed with joists.

Any necessary framing for deck railing is added before the decking, while stairs are added after completing the decking.
