What is a Fungi or Borate Treatment?

A borate treatment is made to the exposed wood surfaces in your crawl space to arrest the growth of wood-destroying fungi and to help protect the wood from insect attack.  A borate is environmentally safe, odorless, and colorless.  Treatment efficacy is approximately 7 years.

Why should I consider a Borate Treatment?

Borate treatments are performed for a variety of reasons.  The primary reason would be as a preventative measure, due to the long-lasting protection.  A borate treatment leaves the wood unpalatable to wood-destroying insects in addition to being effective for control of other pests such as: beetles, crickets, roaches, etc.

The borate treatments we offer serve to ensure the integrity of the wood in your crawl space.  Under certain conditions, wood-destroying fungi, algae, white rot, brown rot, poria incrassata, and wet rots can form in your crawl space.  In conjunction with other moisture control solutions we offer, this works to halt harmful effects of moisture problems in the crawl.  Pre-treatment is a highly-advisable option.

Primary insects affected by Borate Treatments:

  • Subterranean termites

  • Formosan termites

  • Carpenter ants

  • Powderpost beetles

  • Old house borers

Disclaimer:  It should be understood that problems that may have led to the infestation or that may do so in the future must be corrected.  It should also be understood that while fungal sporing and growth in a crawl space can have some adverse effects on those with sensitivities, this is NOT the same type of dangerous sporing that is termed "toxic mold".  These dangerous molds are those such as Stachybotrys or Chaetomium.  These serious conditions are generally identified by a company qualified to perform air quality testing and are not normally found in crawl space environments.

  • Helps alleviate damage to your home's foundation, footings, wood framing, and sub-floor due to excessive moisture

  • Promotes an environment to inhibit fungal growth and possible termite attack

  • Preserves crawl insulation and vapor barrier by reducing standing water in your crawl space

  • Less expensive that other measures such as french drains or dry wells.
