Ferndale Ask five homeowners in Ferndale what siding replacement costs and you'll get five different answers, because the price of a siding job is never really about the siding itself. It's about what's underneath it, how the house is shaped, and how much correction the crew has to do before a single new panel goes up. Understanding those factors is the difference between a bid that makes sense and one that leaves you wondering what happened halfway through the job.
What Actually Drives the Price
Material is only one line item. The bigger swings in cost usually come from these:
- Tear-off vs. overlay. Stripping old siding down to the sheathing costs more up front than siding over what's there, but it's the only way to see and fix what's hiding behind the old material — and in this climate, that matters.
- Hidden moisture damage. Whatcom County's driving rain and long moss season mean water finds its way behind siding more often than homeowners expect, especially around old flashing and window trim. Rotten sheathing or framing has to be repaired before new siding goes on, and that work isn't visible until the old siding comes off.
- Trim, flashing, and water management. Proper flashing at windows, doors, and rooflines is what keeps water out for the next several decades. It's labor-intensive and easy for a lower bid to skimp on.
- House shape and height. Dormers, multiple stories, steep rooflines, and lots of corners all add labor time, regardless of material.
- Crew experience and crew size. Fiber cement siding in particular has installation requirements — fastening patterns, gaps, caulking, factory-cut edges — that take real training to get right. Rushed or inexperienced labor is where most siding failures start.
Rough Cost Tiers by Material
Exact numbers depend on your home's size and condition, but here's how the common options generally stack up against each other in relative cost and what you're paying for:
| Material | Relative Cost | What You're Paying For |
|---|---|---|
| Vinyl | $ | Lowest material cost, fastest install, shortest realistic lifespan |
| Engineered wood (LP-type) | $$ | Wood look at a lower price than fiber cement, more sensitive to moisture over time |
| Fiber cement (James Hardie) | $$$ | Non-combustible material, factory-baked finish, longer service life, stronger warranty |
| Cedar | $$$$ | Natural wood appearance, ongoing maintenance and refinishing required |
The lowest number on a bid sheet isn't the lowest number over the life of the siding. A product or installation that needs repainting, patching, or early replacement ends up costing more than the higher upfront bid, once you account for maintenance and how many years it actually lasts.
Why the Cheapest Bid Isn't Always the Cheapest Job
Underbidding usually shows up in one of a few places: skipping tear-off when it's genuinely needed, reusing old flashing instead of replacing it, thinner fastening schedules, or cutting corners around windows and corners where water intrusion actually starts. None of that is visible on install day. It shows up two, five, or ten years later as soft trim, staining, or siding that's failing from the inside out. A fair bid accounts for doing that work correctly the first time, not for cutting it later.
The Whatcom County Factor
Ferndale sits close enough to the water that salt air is a real consideration for anything metal or painted on the exterior of a home — it accelerates corrosion on fasteners and wears down lower-grade finishes faster than homes further inland. Add in driving rain off the Strait and a moss season that keeps north- and shade-facing walls damp for long stretches of the year, and you've got a climate that punishes shortcuts. Siding installed here needs to manage water well at every seam and fastener, not just look good on install day. That's a big part of why we standardized on James Hardie fiber cement: it's non-combustible, holds its factory-applied ColorPlus finish far longer than field-painted materials, and the HZ product lines are engineered for exactly this kind of wet, coastal climate.
Thinking in Total Cost, Not Just Sticker Price
When you're comparing bids, it helps to ask about more than the total number:
- Is tear-off included, or is this an overlay?
- What happens if they find rot or water damage once the old siding is off?
- What's being used for flashing and house wrap, and is it new?
- What's the manufacturer's warranty, and is it transferable if you sell the house?
- How long is the material expected to last with normal maintenance in this climate?
Those answers tell you more about real cost than the bottom-line number does.
