Deck Looking Rough? Refinish, Resurface or Rebuild: The Decision Guide
A gray, splintered deck looks like a disaster and is often a weekend patient. A shiny deck on a rotten frame looks fine and is the actual emergency. The surface tells you almost nothing. Here is the inspection that tells you everything, and what each verdict costs.
The five minute inspection
Grab a screwdriver and check these five spots:
- Ledger board, where deck meets house: probe for soft wood, look for flashing. This is where decks fail dangerously.
- Post bases: probe at ground contact. Posts rot from the bottom up.
- Joists, from below: dark streaks and soft spots, especially under board gaps.
- Stair stringers: the hardest working, wettest wood on the deck.
- Railing posts: grab and shake. Movement means failed connections.
Verdict one: sound frame, tired surface. Refinish.
If the screwdriver finds solid wood everywhere, your deck needs labor, not lumber. Replace the worst boards, sand everything to clean wood, and finish with a penetrating stain on a dry week. Cost for a typical porch or small deck: $900 to $2,500. The before and after photos in our refinishing gallery are exactly this treatment.
Verdict two: sound frame, dead boards. Resurface.
When boards and rails are past saving but the structure passes inspection, keep the frame and replace the surface, ideally in composite so this is the last time. Resurfacing runs $25 to $45 per square foot, roughly half the cost of full replacement. It is the best value move in deck work and the one most often skipped, because replacing everything is an easier sell.
Verdict three: the frame is going. Rebuild.
Soft ledger, rotted posts or pulling connections mean the structure is done, and money spent on the surface is decoration on a countdown. A new deck built correctly, with footings below frost line and a flashed, bolted ledger, runs $40 to $95 per square foot depending on materials, and then stays boring for decades. When we deliver this verdict, we show you the rot on camera, not just on the invoice.
Questions we hear a lot
How often should a wood deck be restained in Pennsylvania?
Horizontal surfaces every two to four years, verticals roughly double that. Penetrating stains age gracefully and recoat easily. Film forming products look great for two years and then peel, and stripping them is the most miserable job in exterior work.
Can I put composite boards on my old wood frame?
Often yes, if the frame passes inspection and joist spacing meets the composite manufacturer's spec, usually 16 inches or tighter. We verify both before quoting a resurface.
