Expert siding installation in Seattle. James Hardie fiber cement, vinyl, and wood siding. Durable, beautiful exteriors with a 10-year workmanship warranty.
Your siding does more than define your home’s appearance. It is the primary barrier protecting your walls, insulation, and framing from the Pacific Northwest’s relentless moisture. At K Single Corp, we’ve installed and repaired siding on thousands of homes across King, Snohomish, and Pierce County since 2007. We understand what works in this climate and what doesn’t.
We specialize in James Hardie fiber cement siding (the gold standard for PNW homes) along with vinyl and natural wood siding options. Every installation includes proper house wrap, flashing, and moisture management details that keep water out where it matters most.
James Hardie is the most popular siding choice for Pacific Northwest homes, and for good reason. Their fiber cement products are engineered specifically for our climate zone (HZ5), meaning they’re formulated to resist moisture absorption, freeze-thaw cycles, and the constant dampness that defines Western Washington.
Why Hardie for the PNW:
We install the full range of Hardie products: HardiePlank lap siding, HardieShingle for shake-style accents, HardiePanel for modern board-and-batten looks, and HardieTrim for clean, durable trim details. Whether your home is a 1950s rambler in Burien or a contemporary build in Issaquah, Hardie offers a style that fits.
Vinyl siding is a solid choice for homeowners who want a clean, low-maintenance exterior at a lower price point than fiber cement. Modern vinyl siding has improved significantly. Today’s premium vinyl products offer better color retention, thicker profiles, and more realistic wood-grain textures than the vinyl of 20 years ago.
Vinyl works well for budget-conscious projects, rental properties, and homeowners who prioritize minimal maintenance. It never needs painting, doesn’t rot, and cleans easily with a garden hose. The trade-off is that vinyl is less impact-resistant than fiber cement, can look less substantial up close, and may warp in extreme heat (though that’s rarely an issue in the PNW).
We install premium vinyl siding from CertainTeed and Ply Gem, including insulated vinyl options that add R-value to your walls.
For homeowners who want the authentic warmth and character of natural wood, we install cedar, redwood, and other wood siding options. Wood siding has been a Pacific Northwest tradition for over a century, and nothing matches its natural beauty, especially on Craftsman, mid-century, and cabin-style homes.
The reality of wood siding in the PNW is that it requires more maintenance than fiber cement or vinyl. Regular painting or staining (every 5-7 years), inspection for rot, and treatment for moss and mildew are all part of owning a wood-sided home in Western Washington. For homeowners who love the look and are willing to maintain it, wood siding is a beautiful choice.

|---|---|---|---|---|
| James Hardie Fiber Cement | $6 - $12 | 30-50 years | Low | PNW weather resistance |

Prices include installation. James Hardie is our most recommended option for the wet Pacific Northwest climate due to its moisture resistance and durability.
Every siding project follows a thorough, systematic process:
Free Consultation & Estimate. We inspect your current siding, check for visible moisture damage, measure the home, and discuss material options, colors, and budget. You’ll receive a detailed, itemized proposal within a few days.
Old Siding Removal. We strip the existing siding and inspect the underlying sheathing, house wrap, and framing. This is where we often discover hidden moisture damage that’s been silently deteriorating your home.
Rot Repair & Sheathing. Any damaged sheathing, OSB, or framing is replaced. We’ve found significant rot on homes in Renton, Federal Way, and Des Moines where improper flashing allowed water behind the siding for years.
House Wrap & Flashing. We install new weather-resistant barrier (house wrap) and detail all flashing around windows, doors, and wall penetrations. Proper flashing is the single most important factor in preventing future moisture damage.
Siding Installation. Our crews install the siding according to manufacturer specifications, with correct nailing, gapping, and joint details. Trim, corners, and transitions are carefully finished for a clean, professional appearance.
Cleanup & Final Walkthrough. We clean up all debris, inspect the completed work, and walk you through the finished project. Your 10-year workmanship warranty is activated on the spot.
Siding is one of the highest-impact home improvements you can make. It transforms the appearance of your home while protecting its structure. Homes in the Puget Sound region face unique challenges from moisture, and the right siding installed correctly is your best defense.
We serve homeowners throughout King County, Snohomish County, and Pierce County, including Seattle, Bellevue, Kirkland, Redmond, Renton, Kent, Burien, Tacoma, Everett, and all surrounding communities.

We install all major siding types, with fiber cement (James Hardie) being our most popular recommendation for PNW homes. It resists moisture, won't rot, holds paint for decades, and looks great on any architectural style.
In the Pacific Northwest, what's behind the siding matters as much as the siding itself. We install house wrap, flashing at every window and door, and maintain proper air gaps so moisture can escape.

James Hardie fiber cement siding is a premium product made from cement, sand, and cellulose fibers. It's thicker, more durable, and more fire-resistant than vinyl. It holds paint longer, resists impact damage, and doesn't warp or melt. Vinyl siding is a more budget-friendly option that's low-maintenance and comes in many colors, but it's thinner, less impact-resistant, and can look less substantial. For PNW homes, we generally recommend Hardie for its superior moisture and durability performance.
Siding costs vary by material and home size. James Hardie fiber cement siding typically runs $10-$16 per square foot installed, while vinyl siding ranges from $5-$9 per square foot installed. For a typical 2,000 sq ft home, expect $15,000-$35,000 for Hardie and $8,000-$18,000 for vinyl. Wood siding varies widely by species and style. We provide detailed, itemized estimates during your free consultation.
Yes, especially if we add insulated sheathing or fan-fold insulation beneath the new siding during installation. Many older PNW homes have minimal wall insulation, and a siding replacement is the perfect opportunity to improve your building envelope. James Hardie also offers HardieWrap weather barrier, which reduces air infiltration. Homeowners frequently notice lower heating bills after a siding upgrade.
James Hardie fiber cement siding carries a 30-year non-prorated product warranty and can last 50+ years with proper maintenance. It's specifically engineered for different climate zones, and the HZ5 formulation is designed for areas with frequent freeze-thaw cycles and moisture, making it ideal for Western Washington. It doesn't rot, warp, or attract woodpeckers like wood siding can.
A full siding replacement on a typical single-family home takes 1-3 weeks depending on the home's size, the complexity of the trim work, and weather conditions. Homes with multiple stories, intricate architectural details, or significant rot repair behind the existing siding may take longer. We provide a timeline estimate during your consultation and keep you updated throughout the project.
We do both. If your siding has localized damage, a few cracked boards, a section with moisture damage, or storm damage to one wall, we can often repair the affected area and match the existing material and paint color. However, if the damage is widespread or the siding is at the end of its lifespan, full replacement is more cost-effective and gives you a consistent, updated look across the entire home.
Rot behind siding is common in PNW homes, especially around windows, doors, and areas where flashing was improperly installed. When we remove the old siding, we inspect the entire sheathing and framing for moisture damage. Any rotted plywood, OSB, or framing members are replaced before new house wrap and siding are installed. We document all rot repair with photos and include it in the project scope.
Most full siding replacements require a permit in Seattle and surrounding jurisdictions. Permit requirements vary by city across King, Snohomish, and Pierce County. We handle all permit applications and city inspections as part of your project so you do not have to manage any of the paperwork yourself.
Yes. We offer financing options through third-party lenders to help homeowners manage the cost of a siding replacement. Monthly payment plans with competitive rates are available, making it easier to invest in a premium product like James Hardie without paying the full amount upfront.
