Seattle alone takes about 37 inches of rain across roughly 155 wet days a year, and that water is steadily rotting the cedar and builder vinyl on three million Washington walls. We build the material pages, the wood-rot and re-side pages, and the galleries that put Washington siding contractors in front of those homeowners when the search starts. Flat $1,500 a month, built around how people here actually search.
The Washington market
Washington has about 3.3 million housing units, and a large share of them wear cladding that the climate is actively working against. West of the Cascades, the wet stretch from November through February soaks siding for months at a stretch, and the cedar that builders loved through the 1970s, 80s, and 90s pays for it. Cedar resists decay; it does not defeat it. Once paint or stain fails, raw wood drinks moisture at the board ends, the nail holes, and the bottom courses, and dry rot sets in behind a wall that still looks fine from the street. A Washington re-side is rarely impulse. It is a Ballard bungalow whose cedar finally gave out, a 1990s Snohomish County tract home whose original vinyl has chalked and cracked, or a buyer who pulled a board during inspection and found punky sheathing underneath. Every one of those jobs begins the same way here: weeks of searching long before a contractor's phone rings.
Here is the part most contractors miss. The homeowner doing that searching is not asking a generic question; they are asking a Pacific Northwest question. They want to know whether fiber cement holds up better than cedar in this rain, whether a rainscreen is worth the upcharge, whether their stucco can be re-clad, what a James Hardie re-side actually runs on a Seattle two-story. Search any of that plus a Puget Sound suburb and you mostly get a wall of Angi listings, a roofing company that bolted siding onto a menu, and a few one-page sites that answer none of it. The lead sellers rank because nobody local built anything better. A Washington siding contractor with honest material pages, a real wood-rot and re-side page, and galleries organized by product and town is not fighting a crowded field. They are filling a gap the directories only hold because the gap was left open.

Licensing & trust
Read this part closely, because Washington works differently from the licensing states and homeowners here know it. The Department of Labor & Industries registers siding contractors as a specialty trade, but there is no state exam and no skills test to clear. You file a bond and proof of insurance, pay the fee, and you are registered. That keeps the bar to entry low, which means a homeowner cannot read your L&I number as proof you can actually hang a wall. The credibility that separates you from a casual operator has to be built somewhere else, and your website is exactly where you assemble it.
L&I recognizes 63 specialty classifications under WAC 296-200A-016, and siding is one of them, covering wood, wood products, vinyl, aluminum, and metal siding. Unlike electricians or plumbers, siding contractors clear no examination to register, so an L&I number proves you filed a bond, not that you know the trade.
A specialty siding contractor must post a $15,000 surety bond, up from $6,000 since July 2024, plus general liability of $200,000 public liability and $50,000 property damage, or $250,000 combined single limit. Stating your active registration, bond, and coverage plainly is a trust signal precisely because the fly-by-night crews often cannot.
L&I actively pushes homeowners to look up a contractor's registration before hiring, and many do. Putting your L&I registration number on the site, where it can be checked in seconds, turns that habit in your favor instead of sending the homeowner off to verify a competitor who displayed theirs and you did not.
Because the state runs no exam, a James Hardie or LP SmartSide installer certification does real work in Washington. It proves training a homeowner can confirm, and it catches the brand searches the manufacturers' advertising creates. In a registration-only state, a verifiable certification is the closest thing to a license you can put on the page.

Where the work is
The wettest, oldest-housing market in the state, and the most lucrative re-side territory. Bungalows in Ballard, Wallingford, and West Seattle wear failing cedar, while Bellevue, Redmond, and Kirkland hold 80s and 90s stock now due for replacement. Buyers here research everything, compare fiber cement against cedar, and shortlist the contractor whose pages answered the rainscreen and rot questions first. Content and a clean gallery win this market.
Older, more affordable housing across Tacoma, Lakewood, and Puyallup means a steady mix of full re-sides and rot repair, not just like-for-like swaps. The same maritime rain that hits Seattle works on these walls, and many of these homeowners are price-sensitive comparison shoppers, so an honest cost page and visible reviews matter more here than a flashy brand.
Across the river from Portland, Clark County took years of fast growth, and its 90s and 2000s subdivisions in Vancouver, Camas, and Battle Ground are aging into re-sides together. Same wet winters as Portland, same dry rot at the board ends, and a market where many homeowners search across the state line, so being clearly local to Southwest Washington is its own advantage.
East of the Cascades the climate flips: cold, snowy winters and hot, dry summers instead of constant rain. Freeze-thaw cycles make brittle vinyl crack and the occasional hailstorm punishes it, which pushes a real share of Spokane re-sides toward fiber cement. The material conversation here is different from the wet side, and a contractor who writes for it owns searches the Seattle-focused competitors never touch.
From the capital out across Kitsap, older waterfront and wooded-lot homes sit in some of the dampest air in the state, where shaded north walls almost never dry out and rot is a constant. These are smaller, dispersed markets where most siding searches still return directories instead of a real local company, exactly the vacuum a proper town-level page fills.
Seasonality
The dry window is the work window, and it is narrow. West of the Cascades, reliable install weather runs roughly May through September, and crews stack their best jobs into those months because tearing into a wall during a February atmospheric river is asking for trouble. That compression is exactly why the off-season decides who gets the summer. The homeowner whose cedar started weeping at the seams over a dark, wet winter does not call in January; they search, they read, they shortlist, and they book the company whose pages answered them when spring finally breaks. The contractor sitting at the top of those searches in March collects the calendar before competitors have woken up.
Then there is the rot clock running quietly underneath all of it. Months of Puget Sound rain do their damage out of sight, so the discovery often comes during a spring repaint, a roof job, or a home inspection, when someone finally pokes a soft board and the re-side conversation starts. East of the mountains the rhythm shifts to freeze-thaw: a hard Spokane winter cracks brittle vinyl and the calls cluster as the snow clears. Both patterns point the same direction. Google moves on a delay of months, so the ranking that catches the spring rush or the post-winter Spokane wave was earned the season before. Build the material pages, the galleries, and the review base through the wet months, and you are positioned when the dry season and the rot discoveries arrive together. Start inside the busy stretch and you spend it paying to catch up.
