Alabama Hill is one of Bellingham's older residential pockets, a rise of mixed-era homes tucked under mature fir and cedar canopy near Whatcom Falls Park. A lot of the housing stock here dates from the postwar decades through the 1970s, which means a lot of original wood siding, a lot of shaded north- and east-facing walls, and a lot of homeowners now facing the same question: what does it actually cost to replace tired siding with James Hardie fiber cement, and why do the quotes they're getting vary so much? This page walks through realistic ranges, the factors that push a project toward the low end or the high end, and what to look for when you're comparing bids from different Whatcom County contractors, including our crew at Alpine Exteriors.
There's no single number that applies to every Alabama Hill home, and any contractor who quotes a firm price before measuring your walls and pulling back a section of existing siding is guessing. That said, homeowners in this part of Whatcom County who move forward with a full James Hardie re-side typically end up somewhere in the low five figures for a smaller, simpler home up to well into the $30,000-$40,000+ range for a larger two-story house with significant trim detail and substrate repair. On a per-square-foot basis, most installed fiber cement projects in this market land in a broad band that's meaningfully higher than vinyl but generally more moderate than a full masonry or stone-veneer approach. The spread inside that range comes down almost entirely to what's happening behind your current siding and how detailed the exterior is, not just how many square feet of wall you have.
The table below breaks out the main variables we walk through with homeowners during an estimate, and roughly how each one nudges the final number.
| Cost Factor | What Pushes It Low | What Pushes It High |
|---|---|---|
| Siding profile & texture | Standard lap siding, smooth or standard woodgrain finish | Board-and-batten, staggered shingle panels, or mixed profiles on one elevation |
| Substrate condition | Sheathing is dry and sound once old siding comes off | Rot behind siding on shaded or north-facing walls requires sheathing and framing repair |
| Trim, corners & fascia detail | Simple rectangular walls, minimal window/door trim | Dormers, multiple roof pitches, wide window casings, exposed rafter tails |
| Finish | Factory-applied ColorPlus finish in a stock color | Custom field-applied paint, or a ColorPlus color requiring special order |
| House size & stories | Single story, straightforward footprint | Two-plus stories, steep gables, staging or lift equipment needed |
| Site access | Flat, open lot with easy material staging | Hillside lot, retaining walls, mature landscaping, or a tight driveway typical of older Alabama Hill parcels |
Beyond the table, a handful of region-specific realities tend to be the biggest swing factors on Alabama Hill and elsewhere in Whatcom County:
A trustworthy siding quote for an Alabama Hill home should spell out more than a bottom-line number. Look for these line items before you sign anything:
If a quote is missing several of these, ask why before assuming it's simply a better deal.
The widest quote spreads we see on Alabama Hill projects usually come down to scope, not skill. Before comparing dollar figures side by side, confirm that each bid covers the same product line, the same profile, and the same assumption about tear-off versus overlay. A bid that's dramatically lower may simply be excluding rot repair, using a thinner or lower-grade trim package, or skipping the rainscreen detailing that a rain-heavy climate like ours benefits from. Confirm each contractor's Washington state contractor license is active and ask how much fiber cement-specific experience their crew has, since Hardie requires different blades, fastening patterns, and cut-dust handling than vinyl or wood. Alpine Exteriors is licensed in Washington under license ALPINI751OW, and we'd encourage you to check that kind of registration for any contractor you're considering, not just us. It's also fair to ask two or three contractors to itemize their bids using a similar format so you can actually compare line by line instead of just comparing bottom-line totals.
Most contractors, including Alpine Exteriors, can point you toward financing options through third-party lenders or manufacturer-affiliated programs, and a home equity line of credit is another common route homeowners use to spread out the cost of a full re-side. Whichever path you consider, compare the total interest cost against simply saving up and timing the project, since siding replacement is rarely an emergency unless there's active water intrusion.
On the insurance side, it's worth understanding the limits going in. Standard homeowner's policies generally treat gradual deterioration, wood rot from long-term moisture exposure, and lack of maintenance as excluded, ordinary wear rather than a covered loss. A sudden, identifiable event, like storm damage that tears siding loose or a fallen limb that punctures a wall, is a different story and is more often covered, particularly if you have clear documentation and a licensed contractor's assessment to support the claim. That's one more reason to address rot and failing siding proactively on an older Alabama Hill home rather than waiting for it to become an insurance gray area.
Timelines depend heavily on house size, roofline complexity, and how much substrate repair is discovered once the old siding comes off, but most single-family re-sides in this area run from roughly a week to a few weeks of active work, with weather and material lead times sometimes extending that window during the wetter months.
It depends on the condition of what's underneath. If your current siding is sound, flat, and free of moisture damage, an overlay approach with proper furring may be possible in some cases, but many older Alabama Hill homes have enough hidden rot or an uneven substrate that a licensed contractor will recommend full tear-off to do the job correctly.
James Hardie fiber cement doesn't absorb and swell the way wood siding can, and it resists moss and algae growth better than untreated wood, but it isn't maintenance-free. Proper installation with a correctly detailed drainage plane and flashing matters just as much as the material choice for keeping moisture problems from developing behind the wall.
In most cases, exterior siding replacement requires a building permit, and requirements can shift slightly depending on scope of work and whether insulation or sheathing is also being altered under the Washington State Energy Code. A licensed contractor should be able to confirm the specific requirement for your property and handle the permit application as part of the project.
If you're weighing a siding project on Alabama Hill or elsewhere in Whatcom County, the most useful next step is an in-person estimate where a contractor can actually assess what's behind your current siding, not just guess from curb appeal. Alpine Exteriors serves Bellingham, Ferndale, Lynden, Blaine, Birch Bay, Sudden Valley, and the islands, and we're glad to walk your property, explain what we find, and put together an itemized James Hardie quote you can compare against any other bid you collect.
