Window and Door Warranty Claims: Common Defects and How to Document Them

Why Windows and Doors Are Easy to Dismiss

A window that lets in a draft or a door that sticks a little in humid weather can feel like a minor annoyance rather than a warranty issue. In new construction, though, these symptoms are frequently signs of installation defects that your builder is responsible for correcting under the first-year workmanship warranty.

Common Window Defects

Improper flashing and sealing

Water intrusion around window openings is one of the most consequential defects because it can lead to hidden rot inside the wall cavity long before any staining appears on the interior.

Poor operation

Windows that are difficult to open, do not latch fully, or feel loose in the frame often indicate the unit was installed out of square.

Condensation between panes

Fogging or condensation trapped between the panes of a double- or triple-pane window signals a failed seal and is typically a manufacturer defect rather than a builder installation issue.

Common Door Defects

Sticking or dragging

A door that sticks against the frame, especially one that has gotten progressively worse, can indicate the frame was installed out of plumb or that the surrounding structure has shifted.

Gaps at the threshold

Visible daylight or a draft at the bottom of an exterior door usually means the threshold was not properly adjusted or sealed during installation.

Failure to latch

A door that does not latch securely is both a comfort issue and, for exterior doors, a security issue that should be reported promptly.

How to Document These Defects

Photograph the window or door fully closed and fully open, including a close-up of any visible gap.

Note whether the issue is worse in certain weather conditions, since temperature and humidity changes often reveal installation defects.

Test operation multiple times and describe exactly what happens: does it stick at a specific point, does it fail to latch, is there visible daylight.

Record the date you first noticed the issue, since window and door defects generally fall under the first-year workmanship warranty and that window closes quickly.

When to Call in a Third Party

If a window or door defect seems to be causing water intrusion, or if the builder disputes that an installation defect exists, a written assessment from an independent window and door installer or a home inspector can strengthen your claim considerably.

Small drafts and sticky doors are worth reporting. They rarely fix themselves, and the warranty window to address them is shorter than you think.
