Dry Rot SpreadsāFast
That soft spot in your window trim? It's not staying there. Dry rot fungus spreads through wood like cancer through tissue. By the time you see damage on the surface, it's often deeper than you think.
The most expensive mistake homeowners make: hiring someone who scrapes, fills, and paints. Three years later, the rot has spread to your framing, and now you're looking at a $10,000 repair instead of a $1,000 one.
A dry rot specialist doesn't just fix what you can see. They probe for hidden damage, remove all affected material, treat adjacent wood with fungicide, and install new rot-resistant materials with proper moisture barriers.

Frequently Asked Questions
What is dry rot and how does it spread?
Dry rot is a wood-destroying fungus that thrives in damp conditions. Despite its name, it requires moisture to grow. Once established, it can spread to adjacent wood even if that wood is dry, making early detection and repair critical.
How much does exterior dry rot repair cost?
Exterior dry rot repair in St. Louis typically costs $200-$500 for minor trim repairs, $1,000-$3,000 for fascia and soffit replacement, or $5,000-$15,000+ for extensive siding and structural repairs.
Can I paint over dry rot?
No. Painting over dry rot is a temporary cosmetic fix that allows the damage to continue spreading behind the paint. The affected wood must be completely removed and replaced with treated lumber.
How do I prevent dry rot from coming back?
Prevention requires addressing moisture sources: proper flashing, adequate ventilation, maintained gutters, and regular inspection of vulnerable areas. Using pressure-treated or rot-resistant wood for repairs also helps.
