Crawlspace Fungi / Mold Treatment
- Affordable * Fast * Effective Crawlspace & Attic Treatments
- Wood Decay & Wood Destroying Insect Protection
As you can see in this picture, half of this wood was treated with Bora-Care with Mold-Care and half was left untreated. The wood was placed in a mold incubator for six months. Mold will not grow on the treated side, while the untreated side is covered with fungi / mold growth.
What is Wood Decay / Fungi Growth / Mold Growth

Fungi are living organisms, They grow like a plant. But they eat like an animal. Some of them survive by eating dead organic materials. Others are parasites, living off live food sources. When they use people as a food source, they kill us. But some types of fungi are also helpful. Without fungi, dead leaves would just pile up and never be broken down. Fungi give us antibiotics. They give us beer and wine.
There are three basic types of fungi, and none of them have a place in your home.
Three types of fungi: decay (top), stain (left) and mold (right).
By definition, mold fungi are surface growing organisms that cause a discoloration. They don’t destroy the surface they grow on, but they can cause allergies, respiratory problems and other health issues.
This fungus causes discoloration of wood. While they can present an aesthetic challenge, they are not harmful.
Decay fungi grow in materials and use the structure as a food source. They will compromise the integrity of wood, and devastate a home in the way termites or other wood-eating insects can. Just a 2% weight loss in a piece of wood from decay can cause up to 50% loss of strength
Effects of fungal growth
- Structural failure – if the house collapses or you fall through the floor
- Allergies—mold is similar to pollen grains and may cause allergic reactions, hay fever-type symptoms, even asthma and eczema
- Parasitic growth—athlete’s foot, some lung diseases
- Fungal poisons – there are microtoxins in fungi that can can serious health threats. Symptoms include inflammation of stomach, nose, throat, pulmonary hemosederosis bleeding lung disease liver damage, cancer and death
When does fungus grow?
Water is the enemy. If wood becomes wet enough, you will have a fungal problem. If the air is wet enough, you will have a problem. And it doesn’t take long. Most building materials can develop mold in about a week of exposure to wet conditions.
Different types of moisture
In a brand new home, all materials contain water. For example, in the average 2000 square foot home, there is an average of six tons of water and it can take six months to dry out. The first year of a house needs good ventilation or mold will occur.
Mold growing on wet construction materials.
Weather-related moisture problems
Wet lumber / wood can develop mold in less than 24 to 48 hours.
Water in buildings
- Rising damp – most construction materials wick water quickly
- Penetrating damp – a leak in the house, like a pipe
- Condensation– crawl spaces that aren’t ventilated or AC systems that are below the dew point, will cause condensation, and eventually mold.
