Mold FAQ:

What Causes Mold?
Mold spores exist nearly everywhere in Virginia - in the air we breathe and on virtually any surface. However, mold spores can't colonize and reproduce unless they have oxygen, moisture and a food source. Newer building practices in Richmond, Fredericksburg and Charlottesville increase potential mold problems by decreasing general ventilation of a building and making it more "air-tight" thereby trapping moisture and increasing the chances of mold growth. Consequently, it is vital that new homes in Richmond, Fredericksburg and Charlottesville are protected sufficiently from Mold.

Why are Moisture Problems Are On The Rise?
Homes are built to control moisture through design features like overhangs, gutters and flashing. However, some modern homes, for a variety of reasons, have encountered moisture-related performance problems. 

One of the causes is that houses in Richmond, Fredericksburg and Charlottesville are designed and built with more corners, angles, hips, slopes, nooks, crannies, and other design features that place greater demands on proper detailing and workmanship to keep the weather and water out. Those demands are not always met or require maintenance. Modern energy codes may also be a contributing factor. By encouraging houses to be sealed tightly, these Virginia building codes, experts point out, can exacerbate interior condensation problems, as well as indoor air quality concerns. 

How Can Mold Affect My Health?

  • Mold related allergies: Symptoms can include runny nose, itchy eyes, wheezing, and skin rashes.
  • Allergic fungal sinusitis
  • Infections    
  • Asthma
  • Mold can irritate mucous membranes of the eyes and respiratory system.
  • Volatile compounds (VOCS) produced by mold are thought to cause headache, attention deficit, and dizziness.
  • Toxic molds are reported to cause nausea and diarrhea, depression, headaches, tremors, kidney problems, and infertility.

How does mold form and where?

 

 

 

Studies have found that it takes moisture for mold to form.  Mold in homes usually occurs around fireplace chimneys, windows and doors, and wet areas like bathrooms and kitchens.  Generally, places where moisture is or can be an issue. 

Is mold a real problem?

 

 

 

Currently, there are lawsuits pending in almost every state regarding mold issues.  Builders are not insured for this liability. 

How does MoldStoppers of Virginia treat mold?

 

 

 

MoldStoppers of Virginia treats the inside walls and floor areas in your home.  The MoldStoppers of Virginia installation crews spray moldBlock™ on the inside of the outside walls of the structure, as well as the floor and wet areas, thus creating a protective shell on which mold cannot grow.

How long does it take to dry?

 

 

 

Normally MoldBlock™ dries in approximately one hour; however, in extreme high-humidity climates, it can take up to two hours.

When does treatment take place?

 

 

 

Generally, prior to window and door installation, but definitely before insulation is installed. 

What does the warranty cover and for how long?

 

 

 

The warranty covers the materials and labor replacement of any infected area that has been treated by MoldStoppers of Virginia. This warranty is valid for 20 years.  Every single structure treated by MoldStoppers of Virginia is registered and filed.  The registration form includes the date of treatment, who treated the area, and product batch information.

Can mold grow on my drywall and insulation?

 

 

 

If the drywall or insulation is exposed to enough continuous moisture, yes, mold can grow on these areas if not treated by MoldStoppers of Virginia. However, once the moisture issue has been identified, repairs can be made. Replacing insulation and drywall is far less expensive than removing brick or siding and then replacing the sheathing.

Why do you treat the inside of the structure and not the outside?

 

 

 

Mold grows on the outside of many, many structures in the United States which is not a problem because it has not entered the breathable envelope of the structure.  By creating a barrier on the inside of the exterior sheathing, MoldStoppers of Virginia prevents mold from growing on the inside of the exterior sheathing.
