Deck Repair and Board Replacement in Gainesville

Look at four things and you will catch most of it. Push hard on the guard rails: they should not move, and a rail that flexes is the most common serious defect on an older deck. Look at where the deck meets the house for staining or soft trim, which points at a ledger without proper flashing. Look at the base of every post for softness at the concrete line. And walk the stairs, which take more load and more water than anything else. Anything soft enough to push a screwdriver into is worth having looked at properly.

Repair wins when the frame is sound and the problem is on the surface, and it stops winning quickly once rot has reached joist ends, the ledger, or the posts. The useful way to frame it is what fraction of the structure is being replaced: past roughly a third, you are paying most of the cost of a new deck to keep an old one, and you inherit the original layout and the original mistakes. A contractor who opens the deck up before quoting can tell you which side of that line you are on.

Because that is where the water collects and the sun does not reach. The house wall sheds rain straight down onto that first run of boards, the gap against the wall traps leaves and debris, and the shade means the area dries slowly. Add a ledger that was installed without flashing and the same water is also working on the band joist behind the wall, which is a much more expensive problem. Boards rotting at the house end are worth investigating rather than simply replacing.

It depends where the movement is coming from. A rail that moves because the fasteners have loosened can be re-secured with proper connectors. A rail that moves because the posts were notched too far, bolted with a single fastener, or attached only to the rim board is a rail that was never built to hold the load, and re-tightening it does not change that. Guards are the safety-critical part of a deck, so this is one place where rebuilding to correct geometry and connection is the right answer rather than the expensive one.

Bounce usually means the joists are spanning further than the size and spacing really want, or a beam has lost support, or a post has settled. It is not automatically unsafe, but it is a signal that something is carrying more than it was meant to, and the fix ranges from adding a mid-span beam and posts through to correcting a footing that has dropped. What matters is finding out which, and a floor that has developed bounce it did not previously have deserves attention rather than habit.
