Drafty windows are one of the most common causes of comfort complaints in Clovis homes. Homeowners often notice:
Hot spots during summer afternoons
Cold drafts during winter mornings
Increased HVAC runtime
Uneven room temperatures
Difficulty maintaining consistent indoor comfort
Replacing drafty windows may help improve comfort, reduce unwanted air movement, modernize the home, and support overall building-envelope performance. However, not every draft originates from the window itself. Air leakage can also result from:
Worn weatherstripping
Poor installation
Gaps around the frame
Aging caulking
Wall insulation deficiencies
Structural movement
This checklist and reference kit provides a structured process for evaluating drafty window replacement projects in Clovis, California and helps homeowners understand what should be reviewed before, during, and after installation.
