A Good Housekeeping report identifies five windowsill items that may be damaged when condensation pools: picture frames, plants, books, general clutter and thick curtains. It recommends moving or repositioning them and improving airflow, though the degree of risk depends on how much condensation a home gets and how long surfaces stay damp.
A Good Housekeeping report advises moving picture frames, plants, books and general clutter off windowsills where condensation gathers, and pulling thick curtains away from the glass during the day. The guidance is aimed at reducing the risk of moisture damage and limiting blocked airflow around wet windows.
The report explains that condensation forms when warm, humid indoor air meets cold window glass, causing moisture to collect and sometimes run down onto the sill. If water repeatedly pools around belongings, the report says, frames and photographs may warp, books may become wavy or develop mold, and damp areas can encourage bacterial or fungal growth. These are risks described by the publication, not evidence that every item on a windowsill will be damaged.
Plants can also be affected, according to the report. Soil may take longer to dry in persistently damp conditions, potentially contributing to root rot, while leaves touching cold glass may develop damage. The report recommends moving plants away from direct contact with the window while keeping them in a suitable light source.
For curtains, the advice is to open them during the day so air and room heat can reach the glass, rather than leaving fabric pressed against the window. If a window has trickle vents, the report suggests opening them regularly to support ventilation. Acrylic frames may offer more protection for photographs, but the report cautions that they are not fully waterproof.
Protecting Belongings and Window Areas
The practical point is to reduce prolonged contact with moisture and avoid trapping damp air around the window. Moving vulnerable items can protect sentimental photographs, books and houseplants from preventable damage, while clearing clutter may make it easier for condensation to dry.
The advice also addresses the area around the window itself. The report says blocked airflow and persistent dampness may encourage mold or mildew on frames and nearby walls. It does not present the checklist as a substitute for addressing a persistent moisture problem; rather, it focuses on everyday adjustments that may reduce exposure.

How Condensation Reaches the Sill
The report connects condensation with the contrast between indoor humidity and cold glass, a condition it says can become more noticeable as temperatures fall and indoor heating is used. Moisture may form on the pane, run down and collect on the sill, where objects and fabric can remain damp.
Its five-item list covers different ways belongings can be affected: moisture may seep into frames, damp conditions can harm plants, and paper can become distorted. Clutter and curtains matter because they may restrict airflow or hold moisture near the glass. The piece was written by Good Housekeeping’s Household Advice Editor, Katie, whose supplied biography says she has worked on the publication’s cleaning and home-care content.
“Hot, humid air meets the cold window glass, forcing the moisture to reach its “dew point.””

How Much Moisture Causes Damage
The supplied report does not quantify how quickly condensation will damage an item or specify a moisture level at which the risks become likely. Outcomes may depend on how often water forms, how long surfaces stay wet, the material involved and the conditions in each home.
It also does not provide testing data or cite a separate expert study for each listed risk. Its recommendations are presented as household advice, so readers should not interpret them as a guarantee that moving one item will prevent all mold or moisture problems. The report does not assess the underlying cause of persistent condensation in any particular home.
Practical Steps for Wet Windows
The immediate steps in the report are to clear the sill, move books and photographs to a dry place, and keep plant leaves from touching cold glass. Open curtains during the day, avoid leaving them piled on the sill, and use available trickle vents for ventilation. If water has pooled, dry the affected surface and check nearby items for signs of ongoing dampness.
Readers dealing with recurring condensation can monitor whether the simple changes improve airflow and reduce wet surfaces. The supplied material does not outline a follow-up inspection or announce further reporting, and it gives no home-specific diagnosis. Persistent dampness or visible mold may require advice beyond the article’s windowsill checklist.
Key Questions
Which five things does the report say to move or reposition?
It lists picture frames, plants, books, general clutter and thick curtains. Curtains need not be removed; the recommendation is to open them during the day and keep them from trapping moisture against the window.
Why can books be damaged by condensation?
The report says moisture can make pages look distorted or wavy and may be followed by mold spots and a musty smell. It recommends storing books somewhere dry, cool and away from direct sunlight.
Should I move plants away from a window completely?
The report recommends moving plants off the sill and preventing leaves from touching cold glass, while keeping them nearby if they still receive suitable light. It says persistently damp soil may increase the risk of root problems.
What can I do about condensation behind curtains?
Open curtains during the day to let air and room heat reach the glass, and avoid leaving them tucked against the sill. If the window has a trickle vent, the report suggests opening it regularly.
Does moving these items guarantee mold will not grow?
No. The report offers steps to reduce moisture exposure and improve airflow, but it gives no guarantee or quantified risk estimate. It does not identify the cause of persistent condensation in an individual home.
