Is using hidden fasteners worth the extra effort on a massive 475sf deck?

Those 45-degree hidden fasteners look incredible on day one, but they don't provide the same clamping force as traditional face-screwing. Since the screw only bites into the bottom corner of the board, the top is free to move. If you used pressure-treated lumber that was still wet from the yard, you will likely see some cupping once the sun hits it for a full summer. The boards want to curl upward at the edges, and those hidden screws sometimes aren't enough to hold the tension over such a large surface area. Maintenance is where the hidden system gets tricky. If a board splits or rots five years from now, you cannot just back out two screws and swap it. You will be fighting the angles to get the old fasteners out without chewing up the adjacent boards. For a deck that is 475 square feet, that is alot of potential surface area for things to go sideways. It is a high-end look, but it definitely adds a layer of complexity to future repairs that face-screwing avoids. On the stain front, dark reddish-brown is a magnet for UV heat. The extra heat causes the wood to expand and contract more aggressively than a lighter natural tone. If you used a film-forming stain, you are looking at a peeling situation on those railings in about three to five years. Penetrating oils are much better for a deck of this scale beacuse you can just clean and re-coat without having to sand the whole thing down to bare wood. Sanding 475 square feet of decking and all those railings is a job I woud not wish on anyone.

Using a chainsaw for the demo was the right move. I have seen guys spend three days with a pry bar and a circular saw when they could have just zipped trough the joists in twenty minutes. Since you have got over $11k in materials here, I hope you used **joist tape** on top of the framing. It is the best way to make sure that lumber investment actually lasts twenty years instead of rotting out from the screw holes in ten.

That $11,000 price tag is wild to me as someone just starting out. I’m mostly curious about the chainsaw demo—how do you keep from accidentally nicking the house siding or the foundation when you’re ripping the old boards off? It sounds fast but scary for a first-timer.

Also, for the joist tape the other guy mentioned, is that somthing a beginner can handle easily? If I’m going to spend a few thousand on lumber, I want to make sure I don't mess up the framing right out of the gate.

For the guy asking about the chainsaw—just snap a chalk line about 6 inches out from the house. You cut the main field off first, then use a reciprocating saw for the pieces acutally attached to the ledger. It keeps your siding intact. As for the hidden fasteners, my main worry is ussually the joist spacing. If you are 16 inches on center with hidden screws, you might feel some bounce or see more crowning over time. I usually tighten my joists to 12 inches on center for those jigs just to keep everything rock solid. Did you stick with the standard 16 or go tighter for the extra support?
