How Much Does Deck Repair Cost?
Repair costs depend on the extent of damage and materials involved.Here's a general range for Greater Seattle:
| Minor repairs (boards, railings, steps) | $300 – $1,500 |
| Moderate repairs (structural, multiple areas) | $1,500 – $5,000 |
| Major restoration or near-replacement | $5,000 – $10,000+ |
We provide a free on-site estimate with a written, itemized breakdown — no vague numbers, no surprise add-ons after work starts.
Repair vs. Replacement — What Makes Sense?
Not every damaged deck needs to be torn out. If the structural framing is sound, repairs and resurfacing can extend your deck's life by 10–15 years at a fraction of replacement cost.
However, if there's widespread rot, significant structural movement, or safety concerns — a rebuild may be the smarter long-term investment.
We'll tell you which one applies to your deck after a free on-site inspection. No pressure either way.
Worried About Your Deck's Safety?
Do I Need a Permit for Deck Repair?
Minor repairs — replacing boards, fixing railings, repairing steps — typically don't require a permit in Kirkland, Bellevue, or Redmond.
Structural repairs (replacing posts, beams, or the ledger board) may require one depending on scope and city. We'll let you know upfront what's needed and handle the paperwork if a permit is required.
Common Questions About Deck Repair
-
My deck has soft spots but looks okay on top. Should I be worried?
Yes. Soft spots almost always mean rot underneath — in the boards, joists, or both. The sooner it's addressed, the less it costs to fix. Schedule an inspection before it spreads. -
Can you repair just part of my deck, or does it all have to be replaced?
In most cases, we can repair the damaged sections only. We'll assess what's structurally sound and only replace what's actually necessary. -
How long does deck repair take?
Minor repairs are often completed in a single day. Larger structural jobs may take 2–4 days. We'll give you a clear timeline before we start. -
Can you repair my deck and stain it in the same visit?
Yes — and we recommend it. Combining deck repair and staining saves time and ensures a clean, uniform result. Ask about our repair + staining package when you call.
