Expert Siding Contractor Services
Full Siding Replacement
As a leading siding contractor, we specialize in complete exterior transformations for homes with aging, cracked, or water-damaged exteriors. Our team handles the entire process: removing old materials, inspecting the underlying sheathing, installing high-performance moisture barriers, and rebuilding your home’s protection from the studs out.
Partial or Targeted Repairs
You don’t always need a full overhaul. If you’re dealing with isolated impact damage, dry rot, or pest issues, our experts provide targeted repairs. We focus on structural integrity and meticulous color-matching to ensure your new siding blends seamlessly with the rest of your home.
Siding Upgrades During Roof Replacement
Maximize your investment by hiring a siding contractor who understands the "whole-home envelope." If we are already replacing your roof, it is the most cost-effective time to address siding transitions, flashing, and trim alignment. This integrated approach ensures a completely weather-tight system from the ridge cap to the foundation.
Trim, Fascia & Soffit Renewal
Protect your eaves and elevate your curb appeal. We refresh your home’s architectural edges with durable new trim and paint-grade fascia. These critical components work alongside your siding to prevent moisture intrusion and keep your roofing system ventilated.
Preventive Maintenance Plans
Extend the life of your exterior with our professional maintenance plans. We pair our siding installations with routine inspections that include recaulking, paint touch-ups, and moss treatments, ensuring your home remains the best-looking house on the block for years to come.
Signs you may need new siding
Physical Board Damage: Look for boards that are visibly warped, cracked, or bubbling.
Aesthetic Deterioration: Faded colors or peeling paint are more than just an eyesore; they indicate that the protective layer of your siding has failed.
Compromised Seals: Noticeable gaps at the seams or around the trim allow moisture to penetrate your home's envelope.
Structural Softness: Siding that feels soft or "spongy" when pressed often indicates underlying rot or water saturation.
Decreased Efficiency: An unexplained spike in heating or cooling bills can often be traced back to poor insulation from failing siding.
Biological Growth: The presence of visible mold, moss, or rot is a clear sign of excessive moisture retention.
Interior Moisture: Water stains appearing on inside walls or around window frames often originate from exterior siding leaks.
Siding FAQs
What types of siding are best for the Pacific Northwest climate?
We recommend high-quality, weather-resistant siding materials designed to withstand heavy PNW rain and wind. During your free estimate, we’ll walk you through durable options that resist rot, mold, and moisture damage.
Will new siding help lower my energy bills?
Yes. Upgrading your siding—especially when paired with modern house wrap and insulation—creates a tighter thermal envelope around your home, keeping it warmer in the winter and cooler in the summer while reducing energy costs.
How long does siding installation typically take?
Most residential siding projects take about one to two weeks, depending on the size of your home and the materials chosen. Our experienced crews work efficiently to minimize disruption to your daily life.
Does new siding require a lot of maintenance?
Modern siding materials are incredibly low-maintenance compared to older wood siding. Typically, a simple annual wash with a garden hose and mild soap is all it takes to keep your home’s exterior looking pristine.
Can you replace siding that has rot or water damage underneath?
Yes. As a full-service exterior contractor, we don't just cover up problems. If we discover rot or structural damage during the removal of your old siding, our team is fully equipped to repair the underlying structure before installing your new siding.
