Edgemoor sits right on the water — Chuckanut Drive, South Bay Drive, and the bluffs above Bellingham Bay all take direct wind-driven rain off the bay and the Strait of Georgia for a good part of the year. Homes here also sit under mature fir and cedar canopy, which means near-constant shade, dripping moisture, and moss and algae growth on north- and west-facing walls. Those conditions are exactly why so many Edgemoor homeowners ask about James Hardie fiber cement instead of re-siding with wood or vinyl again. This page lays out realistic cost ranges for the neighborhood, what actually moves the number up or down, what a legitimate quote should include, and how to compare bids without guessing. Nothing here is a quote — every home is different, and the only way to get an accurate number is a walk-around estimate.
Fiber cement siding installed by a licensed, insured crew in Whatcom County generally lands in a wide band, because the material cost is only part of the job. The bigger swing usually comes from labor, wall prep, and how much of the existing siding has to be removed and disposed of versus just covered. Waterfront and view-lot homes in Edgemoor also tend to have more architectural detail — dormers, bump-outs, taller wall sections — which adds labor time compared to a simple rectangular ranch home inland.
| Cost Factor | Typical Low End | Typical High End |
|---|---|---|
| Material tier (lap siding vs. shingle/panel profiles, ColorPlus vs. field-painted) | Standard smooth or woodgrain lap | Shingle-style, board-and-batten, or mixed-profile accents |
| Tear-off and disposal of existing siding | Single layer, easy access | Multiple layers, wood rot, or difficult bluff-side access |
| Wall sheathing and rot repair | Minimal — sound sheathing underneath | Extensive — rotted OSB/plywood, damaged framing |
| House size and wall complexity | Simple single-story footprint | Multi-story with dormers, bays, and steep gables |
| Trim, water-management details, and flashing | Basic trim package | Full rain-screen or upgraded flashing at every penetration |
| Site access and staging | Flat, open lot with driveway access | Steep bluff lot, limited equipment access, tree removal needed |
Put together, a full re-side of a mid-size Edgemoor home in fiber cement typically runs into the tens of thousands of dollars, and it is common for waterfront or heavily detailed homes to land toward the upper end of any regional range once rot repair and site access are factored in. Homeowners who get one quote and assume it represents "the price" of James Hardie siding are usually missing the fact that two homes of the same square footage can cost very differently once wall condition and access are accounted for.
A few things consistently push an Edgemoor estimate higher or lower than a generic per-square-foot figure you might see online:
A usable, comparable quote from Alpine Exteriors or any other siding contractor should spell out, in writing, at minimum: the specific James Hardie product line and profile (lap, shingle, panel), the finish (ColorPlus factory finish or field paint, and which primer/paint system if field-painted), whether tear-off and haul-away of the existing siding is included, what happens if rot is found once walls are opened up (a per-square-foot or time-and-materials rate for repair, agreed in advance), the trim package and flashing details at windows, doors, and roof lines, whether housewrap or a rain-screen system is part of the installation, and a payment schedule tied to project milestones. If a quote is a single lump-sum number with none of that detail, it is hard to compare against a more itemized bid, even if the bottom-line figure looks lower.
The cheapest number on paper is not always the better deal once you account for scope. When comparing bids for Edgemoor homes, line up each quote's material tier, whether tear-off is included, how rot repair is priced, and what water-management details are specified — a bid that skips housewrap upgrades or uses minimal flashing can look less expensive while leaving the house more exposed to the same wind-driven rain that damaged the original siding. It is also worth confirming that every contractor bidding the job is currently licensed and carrying active liability insurance in Washington; Alpine Exteriors' state contractor license is ALPINI751OW, and any reputable siding company should be able to give you their license number without hesitation. Ask each bidder how they handle discovered rot, what warranty applies to labor versus the manufacturer's product warranty on the siding itself, and how long the crew expects the job to take given your specific lot and access.
Many siding contractors, including Alpine Exteriors, can point homeowners toward third-party financing options that split a re-siding project into monthly payments rather than one lump sum — terms and approval vary by lender and by the homeowner's credit, so it's worth asking early in the estimate process what's currently available rather than assuming a specific rate or term. On the insurance side, siding replacement in Whatcom County is more often driven by age, wear, moisture damage, or a remodel than by a single storm event, so it typically falls outside standard wind or impact claims. That said, if a specific incident — a fallen tree limb, a burst pipe that damaged wall cavities, or similar — caused the damage, it's worth a call to your homeowner's insurance carrier to ask whether any portion of the repair is covered before work begins. Keep any quote, photos of the damage, and the contractor's invoice, since insurers generally ask for documentation either way.
For a climate with this much sustained rain, fiber cement's resistance to moisture absorption, rot, and pest damage is a real advantage over vinyl, and it holds paint and color better over time in an overcast climate. It costs more up front than vinyl, and that difference is a legitimate factor in the decision — homeowners on a tighter budget or planning to sell soon may reasonably choose differently, and there's no single right answer for every home.
Timeline depends heavily on house size, how much of the existing siding has to come off, whether rot repair is needed once walls are opened, and site access on bluff or view lots. A simple, single-story home with sound sheathing underneath moves faster than a multi-story home with extensive trim detail or difficult equipment access — your contractor should give you a realistic range once they've walked the site, not before.
Most residential siding replacement projects in Whatcom County and the City of Bellingham require a building permit, and work needs to meet current Washington State Energy Code requirements for wall assemblies, especially if insulation or sheathing is being added or replaced. A licensed local contractor should handle permitting as part of the project rather than leaving it to the homeowner.
Sometimes, but it depends on the condition of what's underneath. In a climate this wet, installing over siding that's already trapping moisture or hiding rot just seals the problem in rather than solving it, so most reputable contractors, including Alpine Exteriors, recommend removing old siding on homes with any history of moisture issues so the sheathing and framing can be inspected and repaired before new fiber cement goes on.
Every one of the ranges above depends on your specific walls, your specific access, and what's actually underneath your current siding — the only way to know for sure is a walk-around estimate. Alpine Exteriors serves Edgemoor and the rest of Whatcom County, from Bellingham and Ferndale to Lynden, Blaine, Birch Bay, and Sudden Valley, and can walk your property, look at what's driving your specific cost factors, and put together an itemized, comparable quote for James Hardie fiber cement siding.
