Moisture Intrusion Inspections

Compared to the rest of the country, Jacksonville has relatively high humidity most of the year. This, combined with an average annual rainfall of over 52 inches,means moisture intrusion problems are very common in Florida. The most common cause of moisture-based issues is when water is entering the structure either due to poor construction, unrepaired damage or damaged window and door seals.

When completing a moisture intrusion inspection the technician will water test each potential area of water intrusion and then validate conditions using Infra-Red Thermography and a moisture meter. Once the specific area (or areas) of intrusion are identified, a complete repair protocol is provided to assure that the condition is permanently corrected.

Causes of structural damage and mold growth

Nearly everyone remembers the “Chinese drywall” issues that started in 2001. In this case, volatile chemicals used in the manufacturing of the defective drywall caused:

  • Corrosive gasses to leak into homes
  • Damage to copper pipes, wiring and AC coils
  • Moisture problems in walls
  • Unwanted mold infestations

The defective building products immediately allowed moisture issues to develop inside the walls which led to huge mold infestations in affected properties. Besides the structural damage caused by moisture, the biggest concern to Jacksonville property owners was the growth of mold inside of homes and buildings.

Ways To Avoid Moisture Problems

If you have stucco siding, keep in mind it should have a minimum 4 inch clearance above the soil. If you have recently added mulch or vegetation around your home, you may be creating a moisture problem if this clearance is not maintained. Deterioration, discoloration and paint separation are strong signs that you may have a moisture issue behind your stucco. What may surprise some owners of 2-story homes is that these types of issues can happen in-between the first and second story, especially on stucco-over-wood-frame construction. This type of issue is primarily caused by fundamental flaws during the initial construction and is often discovered in a moisture intrusion or WDO (wood destroying organisms) inspection.

Identifying improper applications of exterior insulation

Post-construction improvements can also cause moisture problems. One of the most common is an EIFS installation (Exterior Insulation Finishing System). This upgrade is performed on the building’s exterior walls and provides additional insulation, thereby upgrading the energy efficiency of the residential or commercial property. Typically issues arise with improper application of the EIFS. Examples include improper sealing around home penetration points such as electrical outlets and hose faucets, level versus beveled window seals, and a lack of direction for water run-off points, such as the roof-line and gutters.
