James Hardie is the brand name almost everyone means when they say "fiber cement," and in Bellingham it's the material we install most. There's a good reason for that, and there's a real cost to doing it right. Here's what a Hardie re-side runs in 2026, what moves the price, and why fiber cement is the workhorse in a climate this wet.
For a whole-house re-side in Bellingham, James Hardie fiber cement runs $14,000 to $38,000 in 2026. On a per-square-foot basis, that's roughly $9 to $16 per square foot installed, including tear-off, a new weather barrier, a rainscreen, the siding, trim, and flashing.
What fiber cement actually is.
Fiber cement is a mix of cement, sand, and cellulose fiber, pressed into boards and panels. James Hardie is the largest maker, and its lines (HardiePlank lap, HardiePanel, and HardieShingle) cover the looks most Bellingham homes want. The reason it matters here is simple: it doesn't rot, it doesn't feed mold, it holds a finish far longer than wood, and it resists fire. In a place that gets about 35 inches of rain a year, those are exactly the properties you want on the outside of your house.
What drives the price.
The $14,000 to $38,000 range is wide because several things move it.
| Factor | Effect on price |
|---|---|
| Exterior wall square footage | The biggest single driver |
| One vs. two stories | Two-story adds 15 to 30 percent |
| Profile (lap vs. shingle-look) | Shingle and panel detail cost more than plain lap |
| Rainscreen | Adds $3,500 to $9,000, and it's worth it here |
| Trim package | HardieTrim corners and window trim add up |
| Rot found at tear-off | $1,500 to $6,000 contingency on older homes |

Why install matters as much as the product.
Here's the thing cheap Hardie bids get wrong: the brand name doesn't keep water out. The flashing and the drainage behind the board do. Fiber cement is only as good as the wall assembly it sits on. We install Hardie on a vented rainscreen, lap the weather-resistive barrier correctly, flash the window heads and the kick-outs where the roof meets a wall, and use corrosion-resistant fasteners, which matters near the bay where salt air chews up cheap hardware.
Hardie also has specific installation requirements (clearances to the ground and roof, fastener spacing, joint treatment) that protect both the performance and the manufacturer warranty. A crew that doesn't follow them can void the warranty and trap moisture at the same time. We follow the spec. If you're weighing Hardie against other materials, our Hardie vs cedar vs vinyl comparison lays out the trade-offs plainly.
Fiber cement is only as good as the wall behind it. The Hardie board is the easy part. The flashing and the rainscreen are the job.
Hardie vs. the cheaper options.
Insulated vinyl and engineered wood cost less than Hardie, and they're the right call on plenty of houses, especially rentals and straightforward homes. But fiber cement buys you three things they don't fully match: it won't burn, it holds a finish for many years before it needs refreshing, and it's rigid and dense in a way that reads as a higher-quality exterior. On a home you plan to keep, or one where resale matters, the gap is usually worth it. On a budget re-side, it may not be. We'll give you both numbers and let you decide.
Is Hardie worth it in Bellingham?
For most Bellingham homeowners who plan to stay, yes. The wet marine climate is exactly where fiber cement's rot and mold resistance pay off, and our long damp stretches are hard on wood. Put it on a rainscreen so the wall drains and dries, and a Hardie re-side is a 40-plus-year exterior. The honest caveat: if you're on a tight budget or re-siding a rental, engineered wood or insulated vinyl will protect the house for less, and that's a legitimate choice.
