What pushes the price up

What the price includes
A deck repair quote normally covers a visit to look at the damage, the labor, the new boards or parts, and screws or nails. Lawn Love lists mold or mildew removal and insect damage as separate repairs. Sealing or staining, structural work on joists or posts and any permit are often priced on top, so ask what the number includes. It does not include tax or extras the provider adds on the day.
DIY or hire a pro
Small jobs are good for DIY. You can swap a few boards, replace loose nails and wash off mildew with basic tools. Lawn Love lists replacing nails at $150 to $200 when a pro does it, so doing it yourself can save that. Hire a pro for railings, posts, stairs and anything that holds weight. A weak railing can fail when someone leans on it. Structural work on joists or beams may need a permit, and Always Do Better LLC lists it at $1,000 to $5,000 or higher. If you find soft wood near the frame, stop and get a pro to look before you add new boards.
How to tell you need it
Push a screwdriver into the wood. If it sinks in easily, the board is soft and rotting. Other signs are boards that bounce, nails that pop up, cracks, green or black mold, wobbly rails and stairs that shift. Check the wood under the deck as well, since rot can hide there. Fix small spots early. Damage that spreads into the frame costs much more to repair.
How to judge your quote
- Does the quote say how many boards, posts or rail sections will be replaced?
- Is the damage cosmetic or structural, and does the quote explain how the crew checked?
- Does it name the board material and the finish, such as stain or seal?
- Does it say who pulls any permit and what happens if more rot shows up?
- Compare the total with the range above: $500 to $3,000 per repair for most people in 2026.
Ways to pay less
- Fix small rot early, since frame repair costs more. Always Do Better LLC lists boards at $300 to $800 and structural work at $1,000 to $5,000 or higher.
- Ask for two or three written quotes that list the board count, the railing work and the finish work as separate lines, so you can compare them fairly.
- Pick pressure treated pine for boards on an older deck if you want the lowest material cost per square foot. Lawn Love lists it at $2 to $3.75.
- Bundle jobs. If a crew is already there for boards, ask for a price to seal or stain the whole deck in the same visit.
- Check the deck every spring. Lawn Love lists mold and mildew work at $215 to $515, so wash and seal early to avoid bigger fixes later.
Why this costs more in 2026
Trade labor now runs about $75 to $150 an hour in most of the US. Lumber, steel, copper, PVC and concrete all cost more than in 2024, and freight went up after the oil shock that began with the Iran war in February 2026. Lawn Love's 2026 guide prices board replacement at $10 to $35 per square foot, and both lumber and labor costs feed into that number.
