Deck Footings and Framing: What to Check Before Resurfacing
New deck boards can make an older deck look dramatically better, but the surface is only one part of the system. Before resurfacing, homeowners should know whether the footings, posts, beams, joists, fasteners, rail posts, stairs, and ledger connection are still doing their job.
That matters in Mid-Missouri because decks deal with humidity, heavy rain, freeze-thaw movement, and years of seasonal expansion. If the frame is soft, undersized, moving, or poorly attached, new boards can hide a problem instead of solving it.
Why the structure matters before new boards
Resurfacing only works when the frame underneath is worth saving. If joists are rotting, beams are sagging, posts are shifting, or the ledger is not secure, new decking can make the deck look finished while the real issue remains below the surface.
CoMo Premium Exteriors looks at the deck as a system. The question is not simply, “Can we put new boards on this?” The better question is, “Will this structure support the new surface safely and hold up through Missouri weather?” That matters whether the homeowner is considering wood resurfacing, composite decking, or a fuller rebuild.
Deck footings and posts
Footings should be stable, properly placed, and not visibly settling or heaving. Posts should sit plumb, stay firm, and avoid direct soil contact where rot can develop. Watch for leaning posts, cracked concrete, loose brackets, soil washing away around supports, or sections of the deck that bounce more than they used to.
Heavy rain and freeze-thaw movement can reveal support problems. If a deck feels different after winter or after a season of storms, check the supports before investing in a new surface. CoMo has seen recent Columbia deck projects where the scope involved more than boards alone, including screened-porch or framing considerations that changed the resurfacing conversation.
Joists, beams, and ledger boards
Joists and beams should be solid, not soft, split, badly checked, or water-damaged. Fasteners should still hold securely. The ledger board, where the deck connects to the house, deserves special attention because it has to manage both structure and water control.
Look for rusted hardware, missing flashing, water staining, gaps at the house connection, loose stairs, soft spots near the door, or deck boards that dip in one area. Those signs may point to framing or water issues that resurfacing alone will not fix.
When resurfacing becomes rebuilding
Resurfacing may be a good fit when the frame is solid, properly attached, and only the deck boards or railing details are worn. Rebuilding becomes more likely when the frame is rotted, moving, poorly supported, or near the end of its useful life.
A good inspection should give you a straight answer before you spend money on materials. Sometimes the smartest project is new boards. Sometimes it is a safer, cleaner rebuild.
