Landscape grade can change over time, shifting from diverting water from the foundation wall to funneling water toward it. Wear and tear from rain, ice, heat, freeze/thaw cycles, radiation and wind gradually degrades flashing, gutter seams, window and door sills, leading to water intrusions that left unchecked, result in large and expensive repairs. Your OnGuard Certified Moisture Control Inspector is trained to spot issues as they’re beginning to prevent them from becoming big/expensive problems.

Wind-Driven Rain

Moisture from wind-driven rain leads to increases in moisture content. In humid and coastal areas of the country, this moisture load exerts itself directly on the building envelope and often leads to inner wall cavity condensation and mold growth. An OnGuard Certified Moisture Control Inspector is trained in the latest standardized techniques for understanding the problem and recommendation proven solutions.

In colder climates, wind-driven rain saturates exterior surfaces like brick and mortar, EIFS, stucco, aggregate and other semi-porous and cementitious surfaces. In winter months, this increased moisture content goes through repeated freeze and thaw cycles, quickly weakening materials which leads to premature failure. OnGuard Certified Moisture Control Inspectors can assess the needs of your property to increase the longevity of exterior facades.

Rehabs & Aging Structures

Older buildings requiring rehabilitation and reconstruction often suffer from wind-driven moisture problems. Because their exterior walls contain no or limited vapor barriers, moisture transfer is direct which not only affects the building’s facade but also the entire wall cavity as well as the moisture content and even the finishes (in the form of chipping and flaking paints and sealers) within the building. Download the case study below to understand how an OnGuard Certified Moisture Control Contractor will work with you to create a custom moisture control program for your older home or business.

By understanding how porous and how much moisture is penetrating the exterior of a building as a baseline, upon correction, an OnGuard Certified Moisture Control Inspector will be able to recommend the proper moisture control that promotes both hydrophobicity (moisture resistance) as well as breathability so that the building’s vapor permeance remains in balance.
