When replacing siding in Seattle, homeowners must prioritize a material's ability to withstand a moist climate.
Fiber cement is considered the most practical option for Seattle homes due to its durability and versatile, attractive look.
High cost of living, a contractor shortage, and a short window for ideal siding installation during the dry season contributes to higher-than-average costs for siding replacement in Seattle.
With Seattle being a city with a higher-than-average cost of living and unique moisture concerns, homeowners need to plan and budget wisely for siding replacement. On average, siding replacement cost in Seattle is $17,867.

Materials
The type of siding material chosen for your home dramatically impacts overall cost. The climate in the Pacific Northwest requires homeowners to consider durable, rot-proof options.
The most common siding materials in Seattle include:
Here's a breakdown of siding replacement costs in Seattle using these common materials.
| Siding Material | Cost per Square Foot | Pros | Cons |
|---|---|---|---|
| Fiber cement | $9–$18 | Durable against rot and fire | Brittle and requires repainting |
| Vinyl | $7–$14 | Easy upkeep, low maintenance, and low initial cost | Susceptible to fading and cracking |
| Cedar | $9–$24 | Energy-efficient and resists pests | Can rot over time |
| Metal | $11–$17 | Resists damage from rain and wind | Susceptible to rust and denting |
Demolition and Prep
On average, costs to remove siding in Seattle range from $0.90 to $3 per square foot, including labor and disposal. If the existing siding being removed is a heavier material like stone, you can expect costs of $3 or more per square foot. Meanwhile, vinyl siding removal is closer to $1 per square foot.
If old siding contains asbestos, removal costs can be as high as $11 to $17 per square foot because this task requires licensed asbestos pros with specialized safety equipment, gear, and professional licensing.
Accessibility
Price by square foot generally applies to standard one-story or two-story homes. For taller homes with three stories or more, you can expect to pay 10% to 15% more in labor costs to account for the extra equipment and effort needed to reach the upper levels.
Siding Pro Costs in Seattle
Seattle siding professionals charge between $3 and $11 per square foot in labor costs. In recent years, a shortage of skilled construction laborers has caused building and remodeling costs in Seattle to surge far ahead of national averages. Consult a local siding contractor for an exact quote based on your project’s specifications.
Permits
Replacing siding in Seattle will require an construction permit, especially if you're making changes to the structure, such as adding insulation or switching to a heavier material. Seattle permit fees range from $300 to $900 for standard residential projects. However, homes located in historic districts may face higher permitting costs, as applications must meet additional requirements to preserve the neighborhood's character.
Licensing and Insurance
Washington state requires contractors to be registered with the Department of Labor & Industries (L&I), and carry valid licensure, as well as bond and general liability insurance. These requirements ensure they meet the state’s legal guidelines for siding quality and safety.
Taxes
Washington state imposes a sales tax that varies slightly by locality. Seattle's combined sales tax rate is currently 10.25%, which is applied to the cost of materials purchased for your siding project. Typically, labor costs are not subject to sales tax in Washington. However, if your contractor bundles materials and labor into a single contract, confirm how taxes are handled to avoid unexpected expenses.
Does Replacing Siding in Seattle Increase Home Value?
Yes, replacing old or worn siding in Seattle offers a significant return on investment (ROI) due to the fact that high rain and humidity levels have homebuyers on alert for signs of water damage and mold. By updating old siding, homeowners can avoid potentially costly repairs or remediation.
Adding fiber cement and treated cedar will provide the best ROI because these materials offer the strongest resistance to moisture and general wear and tear in Seattle's wet conditions. A siding professional in Seattle can help you find the siding option that adds the most value to your home.
