The cost to install siding in Seattle ranges from $7,270 to $26,670, with most homeowners paying around $14,550. Your actual cost depends on several factors specific to your home and the Seattle-Tacoma market.
Vinyl is cheapest ($4–$8/sq ft installed), fiber cement is mid-range ($8–$14/sq ft), and wood costs $8–$16/sq ft. Engineered wood offers a good balance.
More exterior wall area means more material and labor. Two-story homes have more wall area than single-story homes of the same footprint.
Removing existing siding adds $1–$3/sq ft. Some contractors install over existing siding if it's in decent condition, saving removal costs.
Adding foam insulation board under new siding ($1–$3/sq ft) improves energy efficiency and can pay for itself in energy savings.
Window trim, corner boards, soffit, and fascia work adds 20–30% to the siding project cost but is essential for a finished, weathertight result.
The Pacific Northwest has moderate to high labor costs. Rain affects exterior scheduling October through April. Green building practices are common and many contractors specialize in energy-efficient work.
Budget $68–$405 for permits and inspections. Your contractor typically handles the permit process, but confirm this upfront.
Year-round construction seasons give you the most flexibility for exterior projects. Take advantage by scheduling during slower months for potentially better rates.
While possible for experienced homeowners, siding installation involves significant complexity. In Seattle, you may still need a licensed pro for permits and inspections. DIY could save $5,600–$7,200 in labor.

Most siding installation projects in Seattle take 5–14 days to complete. The timeline depends on project scope, contractor availability in the Seattle-Tacoma metro area, and seasonal demand. Scheduling during Seattle's off-peak season (typically winter months) can reduce wait times and may lower costs.
Vinyl siding offers the lowest installed cost ($4–$8/sq ft) and requires virtually no maintenance. Fiber cement (like James Hardie) costs more ($8–$14/sq ft) but lasts 50+ years and holds paint better. For long-term value, fiber cement is often the best investment.
Sometimes — vinyl and some other sidings can be installed over existing siding if it's flat and in reasonable condition. However, this hides potential issues like rot or moisture damage. A full tear-off and house wrap installation is recommended for the best long-term results.
