Siding Repair in Georgetown

Georgetown is the oldest neighborhood in the city and the housing shows it: modest 1890-1920 worker cottages sided in drop siding, shiplap, and narrow cedar lap, sitting low in the Duwamish valley where the fog settles and does not lift.

Why Georgetown houses fail the way they do

Georgetown is Seattle's oldest neighborhood — settled in the 1850s and incorporated before Seattle itself — a gritty, artist-friendly enclave wedged between the Duwamish River and Boeing Field. The low elevation along the river valley traps humidity and morning fog, while jet blast, vibration from flight operations, and a century of industrial air have all taken their toll on the wood siding wrapping the neighborhood's historic worker cottages and converted warehouse buildings.

The housing stock is dominated by early-1900s worker cottages — modest 1890-1920 homes originally built for brewery and railroad workers, most sided with original drop siding, shiplap, or narrow cedar lap. The neighborhood also has a significant stock of converted industrial buildings and live/work studios, often clad with a mix of wood, metal, and modern fiber cement. Very few post-war or contemporary single-family homes exist here.

Drop siding and shiplap are profiles you cannot buy at a lumberyard any more, and the cottages here are full of them. Where a board is sound we keep it; where it is not we match the profile so the wall keeps its texture. Face-nailing modern bevel siding into a run of drop siding is obvious from the street and it changes how the wall sheds water.

The second Georgetown pattern is paint that has been recoated over failing wood for decades. On a century-old cottage there can be a dozen layers holding a board together, and once that film cracks the wood underneath takes water fast. Part of the repair here is being honest about which boards are actually still boards and which are paint with a memory of one.

Landmarks we work around here: Georgetown Steam Plant Museum, Oxbow Park along the Duwamish, Airport Way South industrial corridor and Georgetown Brewing and historic taverns.

How rot gets into a Georgetown home

Drop Siding and Shiplap Rot on Century-Old Cottages

Georgetown's worker cottages still wear their original drop siding or shiplap — beautiful historic materials that have now been in service for over a century. The low elevation and river-valley humidity keep these walls damp year-round, causing the wood to rot at base courses, window sills, and anywhere horizontal surfaces trap water. Custom milling matching profiles is essential to preserving the neighborhood's character while making the siding weather-tight again.
Trim and Water Table Decay from River Humidity

Water tables, corner boards, and window trim on Georgetown cottages show accelerated decay from persistent Duwamish River humidity. The combination of low elevation, morning fog, and minimal eave overhangs keeps these horizontal and vertical trim pieces saturated far longer than in upland neighborhoods. We rebuild rotted trim with clear cedar milled to match original profiles and seal with marine-grade finishes to fight the relentless moisture.
Failed Paint Over Original Wood

A century of weathering, industrial air, and UV exposure near Boeing Field causes paint to fail rapidly on Georgetown's original wood siding. Peeling paint exposes bare wood to moisture, accelerating surface rot and making the underlying decay worse. We strip failed paint, treat surface rot with consolidants where the wood is otherwise sound, and apply breathable primer and topcoat systems designed for high-humidity, high-pollution environments.
Live/Work Building Cladding Damage

Converted warehouses and mixed-use buildings near Airport Way often feature hybrid cladding — wood lap over older metal panels, fiber cement patches over original board-and-batten, or modern engineered siding covering structural brick. These assemblies fail where materials meet: wood rots where it touches metal, caulk joints open where rigid and flexible materials flex at different rates, and flashing details leak where no one thought to install them during conversion.

What we rebuild with in Georgetown

Three materials, chosen for how they behave on a wall that stays damp — not for what is fastest to hang.

Georgetown questions we get asked

I own a 1910 worker cottage on Carleton Avenue. Can I replace the drop siding with something more modern?

You can, but many Georgetown homeowners choose to preserve the original drop siding or shiplap profile to maintain the neighborhood's industrial-era character. We can custom-mill matching Western Red Cedar to replace rotted sections, or install James Hardie fiber cement in a profile that closely mimics the original if you want modern durability. If the cottage is a designated landmark or contributing structure, design review may apply — we recommend checking with the Seattle Department of Neighborhoods before finalizing material selection.

How much does it cost to repair siding on a Georgetown cottage?

A typical Georgetown worker cottage (800-1,200 square feet, single-story) costs $12,000 to $25,000 for full siding replacement with custom-milled cedar or fiber cement, depending on the extent of hidden rot and trim restoration required. Targeted repairs — replacing rotted base courses and window trim on one or two walls — run $3,000 to $8,000. Georgetown homes almost always need more substrate repair than expected because the low elevation and river humidity cause rot to spread deeply into sheathing and framing.

Why does the siding on my Georgetown home seem to rot faster than homes in other Seattle neighborhoods?

Georgetown sits at the lowest elevation in Seattle — the Duwamish River valley traps fog and humidity that burns off quickly in upland neighborhoods like Capitol Hill or Queen Anne. Your walls stay damp longer after every rain, and morning fog deposits additional moisture throughout the year. Combined with a century of weathering, minimal eave overhangs on historic cottages, and industrial air that accelerates paint breakdown, Georgetown siding faces the harshest conditions in the city. Proper sealing, drainage improvements, and modern weather barriers during repair are essential to slowing the cycle.
