Repair or Replace Your Deck? Guidance for Seattle Homeowners

Deciding whether to repair or replace your deck comes down to safety, cost, and long-term value. As a Seattle deck builder with 25+ years of experience, we often get asked this exact question. Let’s break down what to look for before making your decision.

When Deck Repair May Be Enough

In many cases, a deck can be brought back to life with targeted repairs. You might only need:

  • Replacing decking boards that are cracked, warped, or rotting

  • Upgrading railings for better safety and a refreshed look

  • Tightening hardware like bolts, hangers, and joist connections

  • Adding joist tape or flashing to protect structural members from future moisture damage

If the frame is still solid and meets current codes, repairing can extend the life of your deck for years at a fraction of the cost of a rebuild.

When It’s Time to Replace

There are situations where repair just isn’t enough. Consider replacement if you notice:

  • Rotting or undersized framing that can’t safely support the structure

  • Ledger board issues (improper flashing, water damage, or separation from the house)

  • Outdated footings that don’t meet modern code or can’t handle today’s larger decks

  • Multiple repairs stacking up—sometimes the costs approach that of a full replacement

For many Seattle-area homeowners, a replacement is also an opportunity to upgrade to composite or PVC decking (like Trex, TimberTech, or Azek), which holds up far better in our wet PNW climate compared to cedar or pressure-treated wood.

Cost Considerations

  • Repairs can range from a few hundred to a few thousand dollars depending on scope.

  • Replacements vary widely depending on size, height, and design features (covered structures, railings, or multi-level builds). In Seattle and King County, full replacements often range between $45–$65 per square foot for composite and PVC decks.

While replacement is a bigger upfront investment, the low-maintenance benefits of modern materials often save money in the long run.

Professional Inspection Matters

The most important step is a professional deck inspection. A qualified deck contractor can:

  • Evaluate the structure for safety issues

  • Advise whether repairs are a safe option

  • Provide replacement designs and material samples if needed

Final Thought

If your deck is showing signs of age, don’t guess—get it inspected. In many cases, repairs are enough, but if safety or long-term durability is a concern, replacement is the smarter investment.
