The Problem
Germantown's suburban development history and Montgomery County climate create the conditions for widespread IGU seal failures across the community.
Germantown shares the same challenging climate as the rest of Montgomery County -- summer highs above 95 degrees and winter lows below 20 degrees.
Germantown's humid summers push moisture through any breach in the window seal. Once the desiccant inside the spacer is saturated and can no longer absorb incoming moisture, condensation forms on the interior glass surfaces and becomes the visible fog you see between the panes.
Ultraviolet radiation from the sun degrades the sealant material throughout its life.
Most Germantown neighborhoods were built between 1985 and 2005 during the area's suburban expansion. The insulated glass units installed during this period are now 20-40 years old, putting them well into the zone where seal failures become common and widespread across entire communities.
Warning Signs
Germantown homeowners should look for these indicators that their insulated glass units need replacement.
A milky, hazy, or foggy appearance between the two panes of glass that does not respond to cleaning from either side.
The fog intensifies on humid summer days and may recede during dry winter weather.
Visible water running between the glass surfaces indicates advanced seal failure with significant moisture ingress. At this stage,
Chalky white mineral deposits on the interior glass surface between the panes are evidence of long-term seal failure.
