13 feet is a long but acceptable span for 2x8s at 24", with the thinner 5/4 deck boards. … Composite deteriorates very slowly, but wood (cedar, pressure treated) much more quickly so composite deck failures are usually on the wood supports. …

at a minimum use metal beam supports bolted/lagged to the post below and through the beam (typically the beam support bracket would be for a non-load bearing connection like for an awning and not the deck … I recommend checking all your framing members for rot and either replacing, or bracing all of them with the understanding that you'll need to replace them or your entire deck soon. …

Typical deck footer construction in freezing locations calls for full-depth concrete footings poured using sonotubes (cardboard form tubes) all the way to a few inches above the surface. … For large deck installations in especially frost-prone areas, they use concrete "bell" footings that are wide at the bottom, these help resist frost heave and upward movement. …

I recently bought a house that has an attached deck in fairly poor shape, so I will be replacing it in the next year or so. … Until then, my children want to play on a spiral slide that is attached to the deck, but it wobbles quite a bit as they move around on it. …

With ledger support at the house, there is only one area that needs cantilevered, at the end of the deck supported by a beam. … In your hypothetical case, in order to need cantilevered on all 4 sides, the deck would have to have joists running in all 4 directions, with 4 beams in a square shape smaller than the deck size. …

No. The dimensions and load capacity of lumber makes substitutions like this difficult. A 4x8 is not equivalent to two 4x4s or two 2x8s. A 4x8 is actually closer to 3.5"x7.5". Stacked 4x4s would be 3. …
