Lynden Siding Why "How Much Does Siding Cost?" Doesn't Have a Simple Answer
Every homeowner in Lynden asks some version of this question, and every honest contractor gives some version of the same answer: it depends. Siding replacement cost is driven by the size and shape of your home, how much of the old siding and sheathing has to come off, what's underneath it, and which material you choose to put back up. Two houses of the same square footage on the same street can land in very different price ranges once you factor in trim complexity, window count, and how much rot repair is waiting behind the old siding.
What we can do is walk you through the real cost drivers so you know what you're paying for — not just a number, but why that number is what it is.
The Big Cost Drivers
- Tear-off and disposal. Removing old siding, hauling it away, and dumping fees add up before a single new board goes up.
- What's underneath. Whatcom County's driving rain and long moss season are hard on wall assemblies. If we find soft sheathing, rotted framing, or moisture damage once the old siding comes off, that repair work gets priced separately — and it's common enough on homes near the coast or under heavy tree cover that we always budget for the possibility.
- House complexity. Dormers, gables, bump-outs, and lots of window and door trim all mean more cutting, more flashing detail, and more labor hours than a simple rectangular wall.
- Material. Vinyl, engineered wood, and fiber cement all carry different material and installation costs. This is the choice that affects your total the most, and it's worth understanding before you compare bids.
- Finish. Factory-applied color systems cost more upfront than field-painted siding, but they shift the recurring cost of repainting off your calendar for a long time.
Why the Cheapest Bid Isn't Always the Cheapest Siding Job
A low bid usually means one of a few things: a thinner or lower-grade material, less prep work behind the siding, or a crew moving fast to get to the next job. In a climate like ours — salt air off the Sound, sustained rain through the fall and winter, and moss that will colonize any surface that stays damp — shortcuts on prep and flashing detail don't show up as a problem on day one. They show up in year three or four, as trapped moisture, soft trim, or paint that's already failing. At that point you're paying for the repair on top of what you paid for the "cheap" job.
This is why we quote based on doing the job to spec — proper moisture barrier, correct flashing at every window and door, and fasteners and material rated for coastal Washington conditions — rather than shaving line items to win a bid on price alone.
Where Material Choice Changes the Math
Vinyl siding has the lowest material cost, and for a homeowner on a tight budget it can look like the obvious answer. But vinyl expands and contracts with temperature swings, can crack in impact or hard freezes, and fades over time with no practical way to refinish it short of replacement. Engineered wood products cost more than vinyl and market themselves as a step up, but they're wood at the core — which means the same moisture sensitivity that makes cedar and primed spruce a maintenance commitment in a wet climate.
James Hardie fiber cement sits at a higher material cost than vinyl, but it's non-combustible, doesn't rot, resists moss and mildew far better than wood-based products, and comes with a factory-baked ColorPlus finish that holds color for decades without repainting. When we run the numbers over a 15- or 20-year window — factoring in repainting cycles, patch repairs, and early replacement that cheaper materials often need in this climate — Hardie is frequently the better value, not just the better product. That's the whole reason we standardized on it and stopped installing the alternatives.
Getting an Estimate You Can Actually Compare
The best way to compare siding quotes isn't to look at the bottom-line number — it's to make sure every bidder is quoting the same scope: same material, same tear-off and disposal, same attention to what's happening behind the wall. Ask each contractor what they're doing about moisture barrier, flashing, and any rot repair they expect to find. A vague answer is a red flag regardless of price.
A Few Questions Worth Asking Any Contractor
- Does the quote include disposal of the old siding, or is that extra?
- What happens to the price if rotted sheathing is found once tear-off starts?
- What moisture barrier and flashing details are included at windows and doors?
- Is the finish factory-applied or field-painted, and what's the warranty on each?
