Wood Fungus Treatment & Removal in Greenville South Carolina

Protect Your Home or Business from Wood Rot and Moisture Damage

Wood fungus — often referred to as wood rot — is one of the most destructive problems property owners face. It weakens the structure of your home or business, damages support beams and floor joists, and creates the perfect environment for other pests like termites and carpenter ants.


At Pest Rx, we specialize in professional wood fungus inspection, treatment, and prevention across Upstate South Carolina. Our expert technicians locate affected areas, eliminate the fungus, and protect your structure from future damage — ensuring your property stays strong and healthy for years to come.

Understanding Wood Fungus

Wood fungus thrives in damp, poorly ventilated environments, such as crawlspaces, basements, attics, or under decks. When moisture levels rise, fungi feed on the cellulose in wood, leading to decay that compromises the wood’s strength.


There are two main types of wood fungus that affect homes:


  • Brown Rot – Causes wood to shrink, crack, and crumble into cube-like pieces.
  • White Rot – Breaks down both cellulose and lignin, leaving wood soft and spongy.

Both types can spread quickly in humid or wet conditions — which makes early detection and professional treatment critical.

Our Wood Fungus Treatment & Removal Process

At Pest Rx, we take a comprehensive, multi-step approach to identify, treat, and prevent wood fungus infestations.


Here’s What’s Included:

âś… Inspection & Moisture Assessment

Our licensed technicians inspect all vulnerable areas — crawlspaces, floor joists, subfloors, basements, and attics — using moisture meters and visual inspection to determine the cause and extent of the fungal activity.

âś…  Targeted Fungus Treatment

We apply professional-grade fungicides and borate-based wood preservatives that penetrate deep into affected areas, killing active fungus and preventing regrowth.

âś… Moisture Source Elimination

Since fungus can’t survive without moisture, we identify and recommend corrective actions — such as improving drainage, repairing leaks, sealing vents, or installing vapor barriers.

âś… Wood Restoration & Protection

If needed, we can reinforce or replace damaged wood and apply long-lasting wood protectants to ensure continued protection against decay and moisture intrusion.

âś… Preventive Maintenance

We offer ongoing moisture and pest management plans to prevent the recurrence of wood fungus or other structural threats.

Frequently Asked Questions


  • What causes wood fungus to grow?

    Wood fungus develops when wood remains damp for extended periods due to poor ventilation, plumbing leaks, or high humidity. Fungi feed on the cellulose in wood, leading to decay if moisture isn’t controlled.

  • Is wood fungus the same as mold?

    Not exactly. While both thrive in damp environments, wood fungus attacks and breaks down the wood itself, while mold grows on the surface. Both can coexist and indicate moisture problems that need correction.

  • Can I treat wood fungus myself?

    DIY treatments rarely eliminate the problem completely. Professional treatments from Pest Rx penetrate deep into the wood and target the source of decay, while also addressing the underlying moisture issues that caused it.

  • Will you repair damaged wood?

    Yes. If wood damage is extensive, we can replace or reinforce affected areas to restore your structure’s integrity, then apply protective treatments to prevent further decay.

  • How can I prevent wood fungus in the future?

    Keep your crawlspace or basement dry with proper ventilation, vapor barriers, and routine moisture control inspections. Pest Rx offers preventive maintenance plans for long-term protection.

  • Are your treatments safe for my family and pets?

    Yes! All of our products are EPA-approved and applied safely by trained technicians. Once treatments have dried, the area is safe for normal use.
