Home / Sierra Pacific Windows
Danko Exteriors is one of Spokane’s few Sierra Pacific Windows Select Remodelers. That’s not a self-given title. Sierra Pacific awards it to installation contractors who meet their quality and training standards. When you hire Danko Exterior Solutions, you get the window and the installation it was designed for.
Most window problems aren’t about the window. They’re about the install. Gaps in flashing, improper sealing, and rushed trim work undo even the best products.
Sierra Pacific builds one of the best wood windows available, controlling everything from their own timberland to final assembly. Danko is one of Spokane’s Sierra Pacific Select Remodelers, a designation that means we’re held to the installation standards Sierra Pacific requires of their top contractor partners.
Clean design. Solid performance. A window install done right the first time.
Not all wood windows are built the same, and the difference usually shows up years after the install — in warped frames, failed seals, and finishes that don’t hold.
Sierra Pacific takes a different approach. As part of Sierra Pacific Industries, one of the largest lumber companies in the United States, they sustainably manage over 2 million acres of timberland in California and Washington. That means they control every step of production, from planting seedlings to delivering a finished window. Most window manufacturers source their wood from outside suppliers and have limited visibility into what they’re actually working with. Sierra Pacific owns the process entirely.
Spokane winters are hard on windows. Cold air, freeze-thaw cycles, and summer UV exposure break down products that aren’t built for it.
Sierra Pacific windows are engineered to handle all of it — moisture-resistant wood treatment, thick aluminum cladding, and tight seals that hold through temperature swings. When the window and the installation are both done right, you feel it in comfort and energy costs year-round.
Most wood treatments coat the surface. CoreGuard Plus goes deeper.
Sierra Pacific’s patented process penetrates right to the core of the wood, blocking water, repelling insects, and preventing the rot and swelling that cut other wood windows short. The formula is water-based with near-zero VOCs — serious protection without harsh chemicals. The result is a window that stays stable and requires far less upkeep over its life.
Sierra Pacific windows give you the best of both materials.
The exterior uses extruded aluminum cladding that is twice as thick as standard roll-form systems — built to take weather, UV, and wear without fading or peeling. The interior stays real wood, available in multiple species and finishes, so the inside of your home keeps the warmth and character that vinyl can’t replicate.
Sierra Pacific offers 70 powder coat and 5 anodized finishes — more standard exterior colors than any other window manufacturer in the industry. All powder coat finishes meet AAMA 2604 or 2605 durability ratings, so the color holds up through years of sun and weather exposure. Custom color matching is also available, making it easy to coordinate your windows with any siding or trim.
Sierra Pacific Windows are backed by a fully transferable 30/20 Limited Warranty — one of the strongest in the industry. That includes 30 years on the exterior coating, 20 years on insulated glass, and 10 years on parts. Because the warranty is fully transferable, it also adds value if you ever sell your home. It’s the kind of coverage that only makes sense when a manufacturer is confident in what they build.

Sierra Pacific Windows are premium wood windows with durable aluminum cladding on the exterior. They're made by Sierra Pacific Industries, one of the largest lumber companies in the U.S., which sustainably manages over 2 million acres of timberland and controls the full manufacturing process from raw timber to finished window. The result is a high-performance window built for strength, design, and long-term stability.
Yes. Sierra Pacific Windows are built to handle moisture, freeze-thaw cycles, UV exposure, and temperature swings — all conditions common in Spokane. CoreGuard Plus wood treatment protects from the inside out, and the thick extruded aluminum cladding resists fading and wear on the exterior. Paired with proper installation, they hold up well through cold winters and dry summers.
Our window installation includes removal of old windows, preparation of the opening, proper flashing and sealing, and trim work. As a Sierra Pacific Select Remodeler, Danko installs to the standards Sierra Pacific requires of their authorized contractors — protecting your home from air and water infiltration and keeping the manufacturer warranty intact.
Most window projects in Spokane can be completed in one to a few days depending on the number of windows and the condition of the openings. We provide a clear timeline before work begins so you know what to expect.
No. The extruded aluminum exterior is designed to resist weather and require minimal upkeep. The wood interior can be maintained like any finished wood surface inside your home. CoreGuard Plus wood treatment also provides deep protection against moisture, insects, and rot, reducing the maintenance demands that come with lesser wood windows.
Sierra Pacific Windows are built to last decades, and the warranty reflects that. They carry a fully transferable 30/20 Limited Warranty — 30 years on the exterior coating, 20 years on insulated glass, and 10 years on parts. That kind of coverage is only possible because Sierra Pacific controls the full manufacturing process, from the timber to the finished window. With proper installation and routine care, these windows are designed to stay stable, resist warping and swelling, and perform well long after lesser windows would need replacing.
Yes. New Sierra Pacific Windows reduce drafts, improve insulation, and help regulate indoor temperatures year-round. This is especially noticeable during Spokane winters when heat loss through old or failing windows adds up quickly. Better-sealed windows mean your heating system works less to maintain comfort.
Yes, and it's often the smarter approach. Replacing windows during a siding project allows for better integration at the openings — cleaner flashing, tighter seals, and trim work that looks intentional rather than patched. Many Spokane homeowners choose to do both at once for a complete exterior upgrade.
Common signs include drafts near the frame, difficulty opening or closing, condensation between the panes, visible wear or rot on the wood, or noticeably higher heating and cooling costs. If you're seeing any of these, it's worth scheduling an energy saver assessment.
Danko installs Sierra Pacific Windows throughout Spokane, Spokane Valley, and the surrounding communities. If you're nearby, we can usually schedule an assessment and walk through your options.
If your windows feel drafty, stick when opening, or show signs of wear, it may be time to take a closer look.
