Why Siding Costs What It Does
Ask five contractors what siding replacement costs and you'll get five different numbers, and homeowners in Chuckanut and the surrounding Whatcom County area are often left wondering which one to trust. The honest answer is that siding pricing isn't really about a single number per square foot — it's the sum of material cost, labor hours, the condition of what's underneath your current siding, and how much your site's exposure to weather demands in the way of moisture protection. Understanding those pieces separately is the only way to compare bids that actually mean something.
This page walks through what drives the price of a siding job, what a fair estimate should include, and where homeowners typically get surprised — either by a lowball bid that grows once the crew opens up the walls, or by sticker shock on a quote that turns out to be complete and correct from day one.

The Three Real Cost Drivers
Material
Material cost varies more than most people expect. Vinyl siding sits at the low end per square foot. Engineered wood products land in the middle. Fiber cement — the category James Hardie belongs to — runs higher up front than vinyl, and cedar or high-end painted wood systems can run higher still depending on grade and finish. Material cost is the number homeowners fixate on, but it's rarely more than half the total bill.
Labor
Labor is often the larger share of a siding project, and it's the part that varies most based on your specific house. A simple rectangular single-story home with easy access costs far less to side than a multi-story home with dormers, steep rooflines, tight side yards, or extensive trim detail. Fiber cement in particular requires more cutting precision, specific fastener patterns, and correct joint treatment than vinyl — that's real labor time, not padding.
Site Conditions
What's happening behind your current siding matters more than either of the above. If the sheathing or framing has taken on moisture damage over the years — which is common on homes that have weathered many wet seasons in this part of Washington — that repair work gets added once the old siding comes off and the crew can actually see what's there. A contractor who tells you a firm total price before any of that is uncovered is either underbidding or hasn't done this long enough to know better.
Cost by Material: A Fair Comparison
The table below is intended as a general framework, not a quote — actual pricing depends on your home's size, complexity, and site conditions. What it's useful for is understanding why the cheapest material rarely produces the cheapest total cost of ownership.
| Material | Relative Upfront Cost | Typical Lifespan | Maintenance Burden |
|---|---|---|---|
| Vinyl siding | Lowest | 15-25 years, shorter in harsh coastal exposure | Low, but cracks and fades; not repairable, only replaceable |
| Primed spruce / builder-grade wood | Low-Moderate | 10-20 years depending on upkeep | High — repainting and caulking on a recurring cycle |
| Engineered wood (LP-type products) | Moderate | Varies widely with installation quality and moisture exposure | Moderate to high — edge and joint sealing is critical |
| Cedar | Moderate-High | 20-30+ years if meticulously maintained | High — staining/sealing on a strict schedule, especially with moss and moisture |
| James Hardie fiber cement | Moderate-High | 30+ years, factory-finish backed by long warranty | Low — non-combustible, dimensionally stable, factory ColorPlus finish resists fading |
We install James Hardie exclusively, so we'll say plainly why: it's the product that holds up to what this region actually throws at a house, without asking the homeowner to become a part-time siding caretaker. More on that below.
The Whatcom County Factor
Chuckanut sits close enough to the water that salt air is a genuine factor in material selection, not a marketing talking point. Salt-laden air accelerates corrosion of fasteners and hardware and speeds up the breakdown of some paints and coatings. Add in driving rain that comes sideways off the Sound during winter storms, and a long, damp moss season that keeps north-facing and shaded wall sections wet for extended stretches, and you have a climate that is genuinely harder on siding than most of the country.
That climate reality changes the cost math in a specific way: materials or finishes that perform fine in a dry inland climate can underperform here, which means more repainting, more caulk maintenance, or earlier replacement — real costs that show up years after the "cheap" install, not on the original invoice. When we estimate a job, we're not just pricing labor and material — we're pricing what will actually survive this exposure with minimal upkeep.
Hidden Costs Homeowners Often Miss
- Sheathing or framing repair — moisture intrusion behind old siding is common on older homes here and isn't visible until the old siding is removed.
- Code-required upgrades — depending on your home's age, a full re-side can trigger requirements for updated house wrap, flashing details, or window trim that weren't part of the original construction.
- Trim and fascia — siding replacement is the natural time to address trim that's failed, and skipping it often means redoing work sooner than expected.
- Disposal and dumpster fees — tearing off old siding generates real debris volume, and this is sometimes left out of "too good to be true" bids.
- Paint or caulk maintenance cycles — with some materials, this is a recurring cost that should be factored into the total cost of ownership, not treated as a separate expense.
Upfront Price vs. Cost Over Time
The most useful way to compare siding options isn't the invoice total — it's the total cost over the years you'll actually own the house. A product that costs less to install but needs repainting every 5-7 years, or that fails early in a wet, salt-exposed climate and needs partial replacement, can cost more over 20 years than a higher-upfront-cost product that needs essentially no maintenance and comes with a long transferable warranty.
This is the core reason our company standardized on James Hardie fiber cement and stopped installing vinyl, LP-style engineered wood, cemplank, Allura, primed spruce, and cedar. Each of those products has real strengths — vinyl is inexpensive and low-maintenance in mild climates, cedar is genuinely beautiful, engineered wood installs quickly. But installed on homes exposed to driving rain, salt air, and a long moss season, they each carry trade-offs — moisture sensitivity, recoating schedules, or shorter practical lifespans — that show up as cost down the road. Hardie's fiber cement is non-combustible, dimensionally stable in wet-dry cycling, holds its factory ColorPlus finish far longer than field-applied paint, and its HZ5 product line is engineered for exactly this kind of climate. It costs more to install. It costs less to own.
What a Fair, Complete Estimate Should Include
Whoever you hire, insist on an estimate that spells out these items in writing before work begins:
- Full removal and disposal of existing siding, including dumpster/haul-away costs
- House wrap or weather barrier replacement, not just reuse of what's there
- Flashing details at windows, doors, and roof-wall intersections
- A clear allowance or process for sheathing repair if rot is found once old siding is off
- Trim, fascia, and corner detail scope — specified, not assumed
- Material brand, product line, and color/finish specified by name
- Warranty terms in writing — both manufacturer material warranty and contractor workmanship warranty
- A realistic project timeline accounting for our wet season
A quote missing several of these isn't necessarily dishonest, but it's incomplete — and incomplete quotes are where cost overruns come from.
Budgeting and Timing Considerations
Because our wet season stretches long and moss growth continues through much of the year on shaded and north-facing walls, timing matters for both cost and quality of install. Scheduling exterior work during drier stretches reduces the risk of moisture getting trapped behind new siding before it's fully sealed, and it typically keeps a project moving on schedule rather than stalling out during a string of rainy days. If you're budgeting for a project later in the year, ask your contractor how they plan around our weather rather than just around their own calendar.
It's also worth budgeting in phases if a full re-side isn't affordable all at once — tackling the most weather-exposed elevations first is a reasonable approach, though it's worth discussing with whoever does your estimate since matching materials and colors later can add its own cost if done years apart.
Getting a Number You Can Actually Trust
The only way to get an accurate cost for your specific home is a walk-through estimate that accounts for your home's size, complexity, current siding condition, and exposure.
