Seattle Siding Cost Factors: What Drives Your Project Price

New siding in Seattle runs $10,000 to $37,500 for a typical home. Four things set the price. The material you pick is one. The labor rate is another. So are the size and shape of the house, plus a few costs unique to King County.

Knowing what drives the number helps you budget and weigh today’s price against what the wall costs later. Here is what moves the cost in Seattle, and how to size up your job.

Material Costs: The Foundation of Your Budget

The material you choose is the biggest line on the bill. It sets the price now and the upkeep for years after.

Fiber Cement Siding Cost: $6-15 per square foot installed Lifespan: 25-50 years Best for: our wet climate; it shrugs off rain, rot, and pests

James Hardie and other fiber cement boards are what most Seattle homes get, for one reason: water does not soak in. No swelling, no warping, no rot. It costs more up front than vinyl. Over a 25-50 year life with almost no upkeep, it earns that back.

Factory-finished board costs more at the start. You get a 15-year warranty against peeling. The color also holds better than site-applied paint. Budget $15,000-30,000 for a 2,000-square-foot home.

Cedar Siding Cost: $5-15 per square foot installed Lifespan: 15-25 years with proper maintenance Best for: old homes, like Ballard Craftsmans, where cedar fits the look

Western Red Cedar is the honest match for an old Craftsman. Nothing off a truck looks better on one. The trade to weigh first: you are back on a ladder to restain or repaint every 3-7 years, or the rain gets in. The upkeep, not the boards, is where cedar gets costly.

Engineered Wood Cost: $5-15 per square foot installed Lifespan: 15-25 years Best for: mid-range budgets that want more rot resistance than plain wood

LP SmartSide and similar boards bind treated wood fibers with resin. That makes them steadier and more water-resistant than plain wood. They cost less than fiber cement and outlast raw lumber. You still keep the joints and trim sealed.

Vinyl Siding Cost: $3-12 per square foot installed Lifespan: 20-30 years Best for: tight budgets, or a rental or flip

We steer most Seattle owners off vinyl for anything but a rental or a flip. It sheds water and needs little upkeep. But it fades, it goes brittle in a cold snap, and buyers here read it as a cheap wall. On a house you plan to keep, the up-front saving bites you at resale. Fiber cement or engineered wood serves you better.

Labor Costs: The Seattle Premium

Labor is 60-70 percent of a siding bill. Seattle crews charge $65-105 an hour. Wages here are high: the cost of living is high, the labor pool is tight, and skilled installers are scarce.

A typical 2,000-square-foot job takes 80-120 labor hours, more if the house is fussy. At average rates, that is $5,200-12,600 in labor before materials.

Regional Labor Factors

• King County wages run above the national average.
• Crews skilled in moisture-resistant work are in demand.
• A short dry season creates scheduling bottlenecks.
• Union wages downtown pull residential rates up.

Complexity Multipliers

• Three-story homes: 10-15 percent labor increase for equipment needs
• Difficult access requiring scaffolding: $500-2,000 additional
• Intricate architectural details: 20-30 percent time increase
• Extensive dry rot repairs: $45-85 per hour additional

Home Size and Architectural Complexity

Square footage sets the baseline. The shape of the house moves it from there.

Size Ranges

• 1,200 sq ft home: $8,388-28,800
• 2,000 sq ft home: $13,325-37,500
• 2,500 sq ft home: $17,475-45,000

These ranges cover materials, labor, old siding removal, and permits. They assume a house of average shape.

Complexity Factors

• Dormers and bay windows need custom cutting and fitting.
• Extra roof lines add trim and flashing.
• Historic details demand careful matching and craft.
• Deep trim around windows, doors, and corners adds time.

A plain rectangular house with little trim lands near the low end. A Victorian-era home in Capitol Hill, or a Craftsman in Ballard with deep trim, pushes toward the high end. Every inside corner is time on the clock.

Old Siding Removal and Prep Work

Pulling the old siding adds $0.90-6.00 per square foot, by material and condition. On a 2,000-square-foot home that is $1,800-12,000 to tear off and haul away.

Removal Costs by Material

• Vinyl or aluminum: $0.90-2.00 per sq ft (lightweight, easier removal)
• Wood siding: $1.50-4.00 per sq ft (potential for hidden damage)
• Stucco or brick veneer: $3.00-6.00 per sq ft (labor-intensive, heavy)

We will not lay new siding over old, and we will talk you out of it. Going over the top hides what you need to see: the sheathing and framing behind the wall. In Puget Sound homes, hidden is where rot lives. Tear it off, look, fix what is wet, then close it up. Skip it and you seal the decay in.

Dry Rot Contingency Budget 10-20 percent contingency for dry rot repairs:

• Minor localized rot: $200-1,000
• Moderate sheathing repairs: $2,000-4,000
• Severe structural rot: $5,000-10,000+

With 156 rainy days a year, finding rot mid-job is normal here, not rare. So read the estimates. A bid with no line for dry rot is not a cheaper contractor. It is one who has never opened a Seattle wall. A crew that knows this climate builds the contingency in.

Permits and Regulatory Costs

The Seattle Department of Construction and Inspections requires a permit for siding work, since it changes the building envelope.

Permit Costs

• Standard permits: $200-500
• Historic districts (Queen Anne, Capitol Hill, Pike Place): $500-900
• Properties in Environmentally Critical Areas: Additional review fees

The fee covers plan review, inspections, and paperwork. Plan on 2-4 weeks for approval on a simple job. Complex or historic homes take longer.

Add the 5 percent technology fee that SDCI puts on every permit. If the walls need structural work, a structural engineer runs $500-1,000 on top.

Seattle-Specific Climate Factors

Pacific Northwest rain asks more of an install than code sets as the floor.

Moisture Management Upgrades

• Weather-resistant barriers: $0.50-2.00 per sq ft
• Rainscreen installation: $1.00-3.00 per sq ft additional
• Enhanced flashing around windows and doors: $50-150 per opening
• Drainage plane systems: $0.75-2.50 per sq ft

These details keep water out of the wall, which is what starts dry rot in a wet climate. In a dry state they are optional. Here they are the job.

A local crew that knows the weather flashes and drains a wall by habit. The lowest bids hit that price by leaving those hidden pieces off. In this climate that is a false economy, and the wall pays for it in a few winters.

Timing and Seasonal Pricing

Peak Season (July-September)

• Highest contractor demand
• Premium pricing: 10-20 percent above off-season
• Best weather for installation
• Shortest project timelines

Shoulder Season (April-June, September-November)

• Moderate demand and pricing
• Acceptable weather with contingency planning
• Better availability for scheduling

Off-Season (December-March)

• Lowest pricing: 10-15 percent below peak
• Significant weather delays possible
• Extended project timelines protecting open walls from rain
• Limited contractor availability

For most Seattle homeowners, fall is the sweet spot on price and weather. Book September or October and you catch the tail of the dry season without paying peak-season rates.

Calculating Your Project Cost

Basic Formula (Square footage × material cost per sq ft) + (Labor hours × hourly rate) + Removal costs + Permit fees + Contingency

Example: 2,000 sq ft home with fiber cement

• Material: 2,000 sq ft × $9 = $18,000
• Labor: 100 hours × $85 = $8,500
• Removal: 2,000 sq ft × $2 = $4,000
• Permits: $400
• Contingency (15%): $4,635
• Total: $35,535

This example assumes an average shape, an accessible one- or two-story house, and routine rot repairs.

Getting Accurate Estimates

Gather Multiple Quotes Get at least three detailed bids from licensed, insured contractors who know the Seattle area. Each quote should list:

• Material costs, with product names.
• Labor hours and rates.
• Removal and disposal fees.
• Permit costs.
• A dry rot repair allowance.
• The payment schedule.

Verify Contractor Credentials

• Washington L&I registration.
• Current insurance and bonds.
• References from recent Seattle jobs.
• Skill with moisture-resistant methods.

Ask About Warranties

• Material warranties (often 25-50 years for fiber cement)
• Labor warranties (typically 2-10 years)
• Moisture intrusion coverage
• Paint or finish warranties

Maximizing Long-Term Value

Weigh the price up front against how the wall performs over decades. Fiber cement at $15,000-30,000 asks for almost nothing over 50 years. Cedar starts near the same price, then wants $800-2,000 every 3-7 years to restain. Call it $6,000-15,000 in upkeep across 30 years.

Count the energy, too. Siding over a good weather barrier trims heating bills in our cool, damp air—$150-400 a year, which adds up over the wall’s life.

Think about resale, too. In King County, new siding returns 65-80 percent of its cost in value, more in sought-after neighborhoods.
