Is window condensation always a sign to replace a window?
Not necessarily. Condensation is always a sign that air is leaking between the panes of glass in your window, but it may not be the best move to replace the whole window just because the fog is there. While the presence of fog will affect the heating bills of those living in extreme climates, most in mild climates will not notice the inefficiency. It's important to note that any window will begin to condense in time due to deterioration. If it's possible, quality windows are better repaired than replaced. However, a window that is severely condensing can lead to mold and rot issues that may affect the structure and health of the inhabitants of the home.
Why Does Condensation Occur?
Condensation can occur for a few different reasons. A seal can fail, allowing warm air into the gap between the panes. For this, a glazier is well-suited. Plus, the glazier won't need to tear the window out to fix it. There could also be gaps or cracks anywhere around the window frame. If there are, they are a very likely culprit. If insulation is visible, pushing it back into place and sealing the area with caulk may do the trick. Having the window frames shrink wrapped prior to installation is also a good way to delay the onset of condensation. Replacing the panes of glass and seals is another method for getting rid of the fog. Glaziers or the window manufacturer can usually perform this work.
Specialty Repair Companies
There are even specialty companies that deal with removing the humidity between the panes. Crystal Clear, for example, installs a valve that expels the moisture. Another company, called DeFogIt, installs a desiccant between the panes to remove the fog. Calfinder is not linked with these companies and cannot verify the quality of their services.
