Point Roberts sits at the end of a small peninsula that hangs south of Tsawwassen, British Columbia, bordered by Boundary Bay to the east and the open Strait of Georgia to the west. It's a beautiful place to own a home and an unusually demanding one to side. The point takes weather off open water from more than one direction, the ground is often damp for long stretches of the year, and because Point Roberts is a U.S. exclave reachable by road only through Canada, getting materials and crews to a job site there takes more planning than it does in Bellingham or Ferndale. All of that shapes what a James Hardie fiber cement siding job actually costs here, and it's worth understanding before you start collecting bids.
There's no single number that fits every house, but homeowners in Whatcom County generally see installed James Hardie siding land somewhere in the range of roughly $9 to $18 per square foot, with a full re-side on an average-sized single-family home often landing between the low $20,000s and the $60,000s depending on size, condition, and detailing. Point Roberts jobs tend to sit toward the middle-to-upper part of that range more often than not, mainly because of what's underneath the old siding and what it takes to get people and materials to the point at all. A straightforward re-side over sound sheathing on a simple rectangular home will cost less than a home with wood rot behind the old siding, steep rooflines, lots of trim, dormers, or a shoreline-facing wall that needs extra flashing and fastening attention.
| Cost Factor | Low End | High End |
|---|---|---|
| Tear-off and disposal of old siding | Minimal if siding comes off in large, intact sections with easy dumpster access | Higher when old siding is brittle, layered, or the driveway/lot access is tight, which adds labor hours |
| Sheathing and rot repair | Low if sheathing tests dry and sound | Can add several thousand dollars if plywood or OSB has to be cut out and replaced due to long-term moisture intrusion |
| Siding profile and install labor | Lower for simple lap siding on a single-story rectangular footprint | Higher for board-and-batten, shingle-style panels, or homes with lots of corners, gables, and cutouts |
| Trim, fascia, and accent detailing | Lower with minimal trim and standard window casings | Higher with extensive trim boards, decorative bands, or custom window and door surrounds |
| Color system | Lower for factory ColorPlus finishes in standard colors | Higher for custom field-painted finishes or premium ColorPlus color selections |
| Point Roberts access and logistics | Lower if a crew is already staged on the peninsula for multiple jobs | Higher when material deliveries and crew travel through the border crossing add scheduling and trip costs |
A handful of things push a Point Roberts quote up or down more than anything else. The first is what's hiding behind the existing siding. Whatcom County gets a lot of steady rain rather than short, intense downpours, and over years that moisture finds its way in wherever caulking has failed, flashing was skipped, or old siding was installed tight to the ground. Wood rot in the sheathing or framing isn't unusual on older homes here, especially ones facing the water where wind-driven rain off Boundary Bay and the Strait pushes moisture into joints and seams that would stay dry in a more sheltered spot. A contractor can't know how much of that exists until the old siding comes off, which is why a wide range is normal at the estimate stage and a firmer number usually comes after tear-off.
Moss and algae growth is another factor, less because it drives structural repair and more because it signals where water sits and dries slowly — north-facing walls, areas under overhangs that never get sun, and low corners near grade. Those spots often need extra prep, additional fasteners, or better drainage detailing behind the new siding to keep the problem from coming right back.
Freeze-thaw cycling matters more the further you get from the water and up into the foothills, but even on the point, occasional cold snaps followed by rain can stress caulking and joints that weren't detailed well the first time. And then there's simple geography: Point Roberts has no direct road connection to the rest of Whatcom County, so materials typically travel up through Canada and back across the border, and crews have to budget real time for that crossing. Some contractors handle it routinely and price it into a normal per-square-foot rate; others treat it as a special trip and add a logistics line. Either way, it's worth asking about directly rather than assuming it's already baked in.
A serious James Hardie estimate for a Point Roberts home should spell out more than a total price. Look for these items broken out or clearly described:
Alpine Exteriors builds its Point Roberts estimates around this same list, because a number without this detail behind it is hard to compare against anything else you're handed.
The biggest mistake homeowners make when comparing siding bids is treating the bottom-line number as the whole story. Two quotes for the same home can differ by thousands of dollars because one includes full sheathing replacement contingency and the other assumes the wall is perfect underneath. Ask each contractor to confirm: the exact James Hardie product and finish, whether the price assumes any hidden rot repair or if that's billed separately once uncovered, what underlayment and flashing system is planned, and what the fastener spec is. Confirm the contractor's Washington state license — Alpine Exteriors holds license ALPINI751OW — and check that they carry current liability insurance, since a job on an exposed, wind-affected property is not the place to find out a crew is uninsured. Ask specifically how they handle material delivery and crew scheduling for Point Roberts, since a bid that hasn't accounted for border logistics can end up stretching out well past its original timeline. And get everything in writing; a verbal walk-through estimate is a starting point, not a contract.
Many siding contractors, including Alpine Exteriors, can point homeowners toward third-party financing options that spread a re-side project into monthly payments, which is worth asking about if a full cash-off tear-off and rot repair pushes the job toward the higher end of the range. On the insurance side, homeowners policies typically cover siding damage from a sudden, specific event — wind tearing off panels, for instance — but they generally do not cover gradual moisture intrusion or long-term rot from age and weather exposure, which is the more common issue found on older Point Roberts homes once the siding comes off. If you suspect storm damage rather than gradual wear, document it and talk to your insurer before work starts. It's also worth checking with your utility provider about any weatherization or efficiency incentive programs that might apply when new siding is paired with added exterior insulation, since upgrades that improve a home's thermal envelope sometimes qualify.
For a property that takes direct wind and rain off open water, fiber cement's rigidity and resistance to moisture-driven warping is a real advantage over vinyl, which can flex, crack in cold snaps, and show gaps at seams over time. It costs more upfront than vinyl, but many homeowners here weigh that against fewer moisture problems and a finish that holds up better to the coastal exposure.
Timelines vary with home size and how much rot repair turns up once the old siding is off, but homeowners should also factor in that Point Roberts jobs can take a bit longer end-to-end simply because material deliveries and crew scheduling have to route through the border crossing. Ask your contractor for a realistic window rather than a best-case estimate.
In most cases, especially if the project involves any sheathing repair or changes to window and door flashing, a permit through Whatcom County will be required. A contractor familiar with local permitting can handle this step, but it's worth confirming it's included in your quote rather than left for you to arrange.
New siding installed with a properly detailed weather-resistive barrier and continuous insulation approach that meets Washington State Energy Code requirements can reduce air and moisture infiltration, which does help with comfort and heating efficiency. It's not a guaranteed dollar-for-dollar payback, but tightening up the building envelope is a real, measurable benefit on a home exposed to steady wind and rain.
Every Point Roberts home carries its own mix of exposure, existing damage, and access challenges, so the only way to get a number you can actually plan around is a walk-through estimate from a crew that knows the peninsula. Alpine Exteriors is licensed in Washington (ALPINI751OW) and works throughout Whatcom County, including Point Roberts, Blaine, Birch Bay, Bellingham, Ferndale, Lynden, and Sudden Valley.
