Deck problems often start small — a soft board here, a loose railing there. But these signs can indicate serious structural issues beneath the surface. Oregon’s wet seasons are tough on wood, leading to rot, rusted fasteners, and shifting footings. If your deck feels bouncy, slopes, or shows visible cracks, it’s time for a professional assessment. We provide honest evaluations and safety-focused recommendations to help you avoid failure and liability.
More Than a Patch Job — It’s a Full Fix
When we repair a deck, we look at the entire structure — not just surface boards. Our process includes checking the ledger board, footings, framing, posts, bracing, and hardware. We replace damaged or underbuilt sections with pressure-treated lumber, install proper flashing, and resecure all components to code. Whether it's rot removal or beam reinforcement, you’ll get a safer, stronger deck built to last through years of use.

Upgrades to Meet Oregon Code Compliance

Not every aging deck needs to be demolished. Many structural issues can be fixed without rebuilding the entire frame. We focus on reinforcing weak points, stabilizing sagging areas, and replacing only the components that are compromised. This efficient approach saves money and reduces disruption while giving you back a safe, attractive outdoor space. Whether it’s hidden rot or old hardware giving out, we make smart repairs that bring peace of mind.

Solutions for Every Type of Damage
From Dry Rot to Footing Failures
Oregon’s wet climate creates the perfect conditions for structural deck damage. We regularly address rot in joists and beams, loose or sinking posts, rusted brackets, and ledger board separation from siding. Every repair is done with code-approved materials and techniques, including added blocking, pressure-treated replacements, and lateral bracing where needed. We don’t just stop the problem — we rebuild it stronger.
Our repair services don’t just solve today’s issues — they help prevent future problems. We reinforce deck framing with hurricane ties, install joist hangers where needed, and add new footings for overloaded or undersized areas. We also upgrade guardrails, secure stairs, and re-anchor loose connections. All reinforcement is completed to current Oregon building codes. Whether you plan to keep your deck or sell your home, it’s a smart investment in safety.
