Woodinville’s wet climate creates perfect conditions for fungal wood decay. Spores are present in the environment and initiate fungal growth in humid conditions, especially when the moisture content in timber is high. Heavy rainfall and humidity cause moisture to penetrate wood siding, decks, and trim, leading to rotten wood that compromises structural integrity. Poor ventilation and leaks contribute to the development of both dry rot and wet rot.
Our certified team identifies moisture sources—the first stage of treatment is to find and fix the source of moisture—and removes damaged wood. Once dry rot is identified, it is important to remove all fruiting bodies and visible spores before decay reaches load-bearing areas. We provide complete rot repair that addresses both visible signs and hidden damage. Dry rot can cause significant structural damage if left untreated, while wet rot is generally less severe.
Every project includes a thorough inspection; identifying dry rot can be difficult in the early stages, as symptoms are not always obvious. Treatment of the surrounding area is performed, and dry rot tends to have a white cotton wool-like appearance that coats the affected timber. Installation of sound timber follows—new wood is used to replace decayed sections, and wood hardener may be applied to strengthen affected areas. We ensure the repair matches your existing materials perfectly. Both types of rot require professional diagnosis and treatment to effectively address the underlying issues.

Full replacements cost thousands more than necessary when focused repair can restore structural integrity. Most contractors push complete tear-outs because they generate higher revenue, not because your home actually needs them. We take a different approach by carefully assessing which sections truly require replacement.
We built our reputation on honest assessments that prioritize restoration over costly removal projects. Our team identifies sound timber worth saving, treats affected areas to stop fungal decay, and replaces only compromised sections. When replacement is necessary, we use new wood to restore severely damaged timber, ensuring a seamless repair and maintaining structural integrity. However, the cost of replacing severely damaged timber with new wood can be substantial, often exceeding the initial repair costs. This strategy saves Woodinville homeowners significant money while delivering superior, long-lasting results. Dry rot repair can involve both treatment of the affected wood and replacement of severely damaged sections, which can increase overall costs.
