How long does a full siding replacement typically take?

Most single-family homes take one to two weeks depending on size, weather, and how much of the existing siding and sheathing needs to be removed and repaired first. Wind-driven rain days in Skagit County can push that timeline out, so we build some flexibility into the schedule.

What should I ask a contractor before hiring them for a siding job?

Ask whether they're factory-trained and certified on the specific product they're installing, how they detail flashing around windows and doors, and whether they'll show you the manufacturer's installation instructions they're following. Also ask for their approach to moisture testing existing sheathing before covering it back up.

Why won't you install vinyl siding if a homeowner specifically asks for it?

We made a decision to specialize in one product system rather than install several brands at different quality tiers, and vinyl's performance in wind-driven marine climates like ours is a real tradeoff we're not comfortable installing our name behind. We'd rather explain that upfront than take a job we have reservations about.

Do all James Hardie boards come with the same warranty?

No — the fiber cement substrate carries one warranty and ColorPlus factory-finished boards carry a separate finish warranty, while field-painted primed board relies on the paint manufacturer's coverage instead. We walk through the current published terms with every homeowner since coverage details can be updated by the manufacturer.

Is moss on siding actually a sign of a problem, or just cosmetic?

In most cases moss and algae growth on siding in Anacortes is cosmetic and related to shade and humidity rather than a sign of material failure, especially on fiber cement. That said, heavy moss buildup can trap moisture against seams and trim over time, so it's worth washing off periodically rather than letting it accumulate for years.

James Hardie: Why It's the Only Siding We Install in Anacortes

One Product, No Exceptions

We get asked fairly often why we don't carry a full lineup of siding brands the way some contractors do. The honest answer is that we made a decision years ago to install James Hardie fiber cement siding and nothing else, and we haven't found a reason to change that. Not vinyl, not LP SmartSide, not Cemplank or Allura, not primed spruce or cedar. This isn't a marketing angle. It's a standard we hold because we're the ones who get the callback five, ten, fifteen years later when a product doesn't hold up to what Anacortes and the rest of Skagit County throw at it.

That's the real test here. A siding product can look good in a showroom and still struggle on a home two blocks from the water. We'd rather narrow our offering and stand fully behind it than sell homeowners something we have reservations about.

What Anacortes Weather Actually Does to Siding

Anacortes sits right on the water, and that changes the math on exterior materials in ways that don't show up in a general Pacific Northwest siding guide. Three things matter most here:

Salt Air

Airborne salt from the surrounding marine environment settles on every exterior surface in town, not just homes facing the water directly. Over time it accelerates corrosion on unprotected metal fasteners and trim, and it degrades some coatings and cladding materials faster than inland products of the same brand and line would wear.

Driving Rain

Anacortes gets wind-driven rain off Rosario Strait and the Salish Sea, not just straight-down rainfall. Wind-driven moisture gets pushed sideways into laps, seams, and butt joints, which is a much harder test for a siding system than vertical rain alone. Products that perform fine in a dry climate, or even in a wetter climate without much wind, can behave differently here.

A Long Moss and Mildew Season

Between the marine humidity and the tree cover common in Skagit County neighborhoods, siding here spends a good chunk of the year damp, shaded, or both. That's the exact condition that lets moss, algae, and mildew get a foothold on cladding, especially on north-facing walls and anywhere siding sits close to landscaping.

None of this is unique to us pointing it out — any siding crew that's worked in Anacortes for a few years has seen it firsthand. What differs is how much a given product's engineering accounts for it.

The James Hardie System — What's Actually Different

Fiber cement itself isn't exotic. What sets James Hardie apart is the combination of the base material, the climate-specific engineering, and the factory finish system, all backed by one manufacturer's warranty rather than pieced together from separate vendors.

Fiber Cement as a Material

James Hardie siding is made from cement, sand, and cellulose fiber, cured into a dense, stable board. It doesn't absorb moisture the way wood-based products do, and it doesn't expand and contract with temperature swings the way vinyl does. It's also non-combustible, which matters more every year as wildfire smoke and ember exposure become a bigger part of Pacific Northwest summers, even for coastal towns like Anacortes that aren't in the direct path of fire risk the way some inland communities are.

How That Compares to the Alternatives

Material	Moisture Behavior	Fire Rating	Typical Weak Point in Marine Climates
James Hardie fiber cement	Dimensionally stable, doesn't swell or rot	Non-combustible	Requires correct install detailing to protect cut edges
Vinyl siding	Doesn't rot, but panels expand/contract with temperature	Combustible, can warp near heat sources	Can crack in cold, fade and chalk under UV over time
LP SmartSide (wood-strand)	Engineered to resist moisture, but wood-based core	Combustible	Edge and cut-end sealing is critical; failures often start there
Primed spruce / cedar	Natural wood, absorbs and releases moisture	Combustible	Ongoing paint maintenance; rot risk if coating fails

This table isn't meant to say every one of those products fails in Anacortes. Plenty of them perform reasonably well when installed correctly and maintained on schedule. But when we weighed long-term performance in a wet, salty, wind-exposed climate against the maintenance and callback risk, fiber cement came out ahead consistently enough that we stopped installing anything else.

HardiePlank, HardiePanel, and HardieShingle — Choosing the Right Line

James Hardie isn't a single product — it's a system of profiles, and part of doing this job right is matching the line to the house and the exposure it's going to face.

HardiePlank lap siding — the most common choice for full-home siding jobs, available in several exposure widths and textures (smooth or cedar-textured)
HardiePanel vertical siding — often used for accent sections, gables, or a modern board-and-batten look
HardieShingle — a shingle-profile option for homes going for a more traditional Pacific Northwest coastal look without using actual wood shingles
HardieTrim — matching trim boards so the whole exterior system, not just the field siding, is fiber cement

James Hardie also engineers its boards by climate zone (HZ5 for colder, wetter regions and HZ10 for milder ones), which affects the moisture and freeze-related engineering baked into the product. Western Washington, including Skagit County, falls into the zone where that cold-and-wet engineering actually matters, so getting the right HZ designation specified isn't a formality.

ColorPlus Technology and Why the Factory Finish Matters Here

One of the bigger differences between a Hardie job and a field-painted siding job is the ColorPlus finish — a baked-on, multi-coat color applied at the factory under controlled conditions rather than painted on site after installation.

In a climate like Anacortes's, that matters for two practical reasons. First, a factory-cured finish adheres and cures more consistently than a coat applied outdoors in variable temperature and humidity, which is exactly what you're dealing with on a job site here most of the year. Second, ColorPlus finishes come with their own extended finish warranty separate from the substrate warranty, and touch-up product is formulated to match, which keeps future repairs or additions looking uniform instead of a visibly different shade of "close enough."

Homeowners can still choose primed Hardie board and have it field-painted if they want a fully custom color, but for most Anacortes projects we recommend ColorPlus specifically because it removes one more variable in a climate that's already working against a fresh paint job.

The Warranty — What's Actually Backed and How

James Hardie backs its fiber cement products with a non-prorated limited warranty that's transferable to a subsequent homeowner, and ColorPlus finishes carry their own separate finish warranty. A few things worth understanding about how that works in practice:

The warranty covers the manufactured product itself — it doesn't replace the need for correct installation, which is why using a factory-trained, experienced crew matters
Transferability adds real resale value; a documented Hardie installation with warranty coverage is something a buyer's inspector and agent will both recognize
Warranty terms and coverage details can change, so we always walk homeowners through the current published terms rather than quoting from memory

We won't claim any siding warranty makes a product bulletproof — no warranty fixes a job that was flashed or fastened incorrectly. But a strong, transferable manufacturer warranty on top of correct installation is a meaningfully better position than a shorter or non-transferable warranty on a product that's already working harder to keep up with the climate here.

Installation Is Where Most Failures Actually Happen

This is worth stating plainly: most siding failures we get called out to assess, on any brand, trace back to installation, not the material itself. Fiber cement is not a forgiving product to install badly, and in a wind-driven-rain climate like Anacortes, small detailing mistakes show up as real problems faster than they would somewhere drier.

Things that matter on every Hardie job we do:

Correct nailing pattern and fastener type — not just "close enough," since over-driven or under-driven fasteners are a common source of cracking
Proper clearance between siding and grade, decks, and roof lines so water has somewhere to go
Rain screen or drainage plane detailing appropriate for a marine climate, not just a basic house wrap
Sealed and painted cut ends, especially on factory-cut boards trimmed on site
Correct flashing at windows, doors, and penetrations — the single most common source of hidden water intrusion on any siding type

James Hardie trains and certifies contractors on its install standards for a reason. We follow those standards because that's the difference between a fiber cement installation that goes twenty-plus years without a callback and one that develops problems in five.

What Drives the Cost of a Hardie Project

Every Anacortes home is different, and we're not going to quote pricing without seeing the house, but these are the factors that generally move the number:

Factor	Why It Affects Cost
Existing siding removal	Tear-off and disposal of old material adds labor beyond a straightforward re-side
Sheathing and moisture damage found underneath	Repairs to rot or damaged sheathing are common on older Skagit County homes and get addressed before new siding goes on
Siding profile and texture chosen	Lap widths, shingle profiles, and trim complexity affect material and labor
ColorPlus vs. field-painted primed board	Factory finish has a different cost structure than site painting
Home size, stories, and roofline complexity	Multi-story homes and cut-up rooflines add scaffolding, cutting, and detail work

The one thing we won't do is cut corners on flashing, fasteners, or drainage detailing to hit a lower number. Those are exactly the items that determine whether a Hardie install lasts the way it's supposed to in this climate.

What to Expect From Us

Because we only work with one product line, our estimates are straightforward — there's no upsell menu of five different siding brands with five different margins. We assess the home, identify what's actually going on with the existing siding and sheathing, and give you a clear scope using the Hardie line and finish that fits the house.
