Our Rot Repair Mission
At Chumley Structural & Foundation Repair, our mission is simple: to restore strength, stability, and safety to homes across Western Washington.
We specialize in rot repair: replacing water-damaged beams, reinforcing weakened framing, and protecting crawl spaces from moisture intrusion that can lead to long-term structural decay. We also address ventilation, drainage, and other crawl space conditions that contribute to hidden rot and deterioration.
From moisture remediation and pest damage to vapor barrier installation and wood replacement, our work protects your home’s structure and longevity. Every service is delivered with care, professionalism, and lasting results. That’s The Chumley Commitment.
Backed by The Chumley Guarantee, we provide clear communication, strong warranties, and skilled workmanship. Whether we’re repairing decayed supports, reinforcing crawl space framing, or preventing future rot, we do the job right the first time.
Our top reviews, referrals, and ratings reflect our dedication. As a trusted local expert in rot repair and crawl space protection, we help you safeguard what matters most: your home.
