Homeowners typically see a wide range for replacing rotted wood siding, driven by siding type, square footage, labor, and surface prep. The cost to replace rotted wood siding includes removal, disposal, underlayment, and finish work, and it can vary significantly by region and project specifics. This article provides practical pricing in USD with clear low–average–high ranges and per-unit guidance.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Material (wood siding) total | $3,000 | $6,000 | $12,000 | Includes common wood options (OSB, plywood backing, and face siding). |
| Labor (installation) | $3,000 | $6,000 | $11,000 | Depends on house size, complexity, and crew rates. |
| Removal & disposal | $500 | $2,000 | $4,000 | Rotted material must be removed and disposed properly. |
| Underlayment & weather barrier | $600 | $1,400 | $3,000 | Includes flashing where needed. |
| Finish & paint or stain | $1,000 | $3,000 | $6,000 | Depending on color, primer, and coating. |
| Permits & inspections | $100 | $500 | $2,000 | Regional rules may apply. |
| Contingency (hidden rot) | $500 | $1,500 | $4,000 | Allocates budget for surprises. |
Assumptions: region, specs, labor hours.
Overview Of Costs
The total project cost typically ranges from about $8,000 to $28,000 for replacing rotted wood siding on a standard single-family home, with many projects landing in the $12,000–$18,000 band depending on size and scope. On a per-square-foot basis, homeowners commonly see ranges from $8 to $20 per square foot for siding plus installation, removal, and finishing. Expect higher costs for large homes, complex exteriors, or premium wood species. Per-unit pricing helps compare options like OSB backing, plywood, and premium face siding.
Cost Breakdown
Installing new siding involves material, labor, and ancillary costs. The table below uses typical columns to reflect common price components. The figures are ranges and assume a mid-range home in a suburban market.
| Component | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials | $3,000 | $6,000 | $12,000 | Includes face siding and backing; wood species affects price. |
| Labor | $3,000 | $6,000 | $11,000 | Labor intensity rises with removal of rot and trim work. |
| Equipment & Tools | $300 | $1,200 | $2,500 | Scaffolding, power tools, and ladders included. |
| Removal & Disposal | $500 | $2,000 | $4,000 | Disposal haul-away and debris mitigation. |
| Weather Barrier | $600 | $1,400 | $3,000 | Water-resistive barrier installation. |
| Finish & Paint/Stain | $1,000 | $3,000 | $6,000 | Color and coating choices influence cost. |
| Permits | $100 | $500 | $2,000 | Local requirements may add to cost. |
| Contingency | $500 | $1,500 | $4,000 | Recommended for hidden rot or framing issues. |

Factors That Affect Price
The price to replace rotted wood siding depends on multiple drivers beyond square footage. Key factors include the siding material choice (standard pine vs. engineered wood vs. fiber cement), the extent of rot behind the siding, and the presence of trim, corners, and decorative detailing. Additional pricing variables include the complexity of the house (hip roof, irregular walls), accessibility for equipment, and the local market’s labor rates. Prices increase with premium wood types and larger surface areas.
Cost Drivers
Two specific drivers can push costs up or down: first, wood species and thickness; second, the scope of rot. For example, replacing rotted siding on a 1,500–2,000 square foot house with basic pine may sit in the lower range, while premium cedar with extensive rot and custom trim can reach the higher end. A detailed assessment of shear rot, framing damage, and moisture intrusion is essential to produce a reliable estimate. Accurate assessment minimizes change orders later.
Regional Price Differences
Prices vary across markets. In the Northeast, where labor costs tend to be higher and moisture risk greater, total projects often run at the upper end of the spectrum. The Midwest can offer mid-range pricing, while the Southwest may show lower overall labor costs but higher material cooling/finishing expense. A typical regional delta can be ±20% to ±35% from a national average, depending on weather, accessibility, and permit requirements. Local market conditions drive the bottom line.
Labor, Hours & Rates
Labor costs hinge on crew size, experience, and travel time. A two-person crew may cover 1,000–1,200 square feet per week in moderate conditions, factoring removal, underlayment, and finish. Labor rates commonly range from $40 to $70 per hour per worker, with higher rates in urban cores or specialized trades. For a standard home, expect 1–2 weeks of work, including setup and cleanup. Efficient crews reduce total project time and cost.
Additional & Hidden Costs
Hidden costs can appear if rot extends into sheathing, studs, or window flashing. Expect extra charges for plywood or OSB backing replacement, mold remediation, and increased disposal fees for demolition waste. Specialty finishes, color-matching, and extended warranties can add to the total. A thorough inspection before bidding reduces surprises. Plan a contingency of 5–15% for unknowns.

Ways To Save
Cost-conscious approaches can trim overall spending without compromising durability. Consider scheduling work during off-season windows when contractors have more availability and may offer lower rates. Bulk discounts on materials, choosing standard trim, coordinating multiple exterior updates, and performing preparatory minor repairs in advance can reduce labor time. Getting multiple bids helps identify fair pricing and avoid overcharges.
