Get Started

Local siding experts who know Northwest weather

In Western Washington, siding doesn’t just face rain — it faces moss, salt air, and long, wet seasons that test even the toughest materials. That’s why Topside focuses on materials that last, installation that’s clean, and maintenance that’s simple.

We’re not just a roofing company that “also does siding.” We’re a licensed, insured exterior contractor with decades of local experience and a track record of clean, efficient, and photo-documented work.

Why homeowners choose Topside for siding replacement

  • Local Expertise: We know how Bellingham’s coastal weather affects different siding types — from fiber cement to engineered wood.

  • Manufacturer Trained: Our team follows exact installation specs for brands like James Hardie, LP SmartSide, and CertainTeed.

  • Full Exterior Integration: We align siding, flashing, and trim with your roofing and gutter system to prevent leaks and improve insulation.

  • Photo Updates and Clear Quotes: You’ll see before, during, and after photos — and always know what’s next.

  • No Mess Left Behind: We respect your home, landscaping, and neighbors. Every project ends cleaner than it started.
