Rattling on windows is more than just annoying: it usually indicates one problem or another that may affect window performance.
What Causes Rattling Windows?
When windows rattle, it is because of one or more of the following:
Worn-out weatherstripping – Weatherstripping seals the gaps between window sash and frame, and also keeps it from vibrating. Old rubber weatherstripping becomes rigid and brittle as it gets worn out, which can lead to gaps that result in rattling.
Loose window glass – It’s not as common nowadays, but some types of traditional windows are made with single-pane glass set into the sash with putty, which shrinks as it ages. When this happens, the glass panels can come loose enough to rattle when hit by wind.
Loose sashes – Old or damaged window hardware as well as warping are common reasons why window sashes can become loose.
Can Rattling Windows be Fixed?
Rattling windows generally indicate compromised performance, which means you will need new windows from your local window contractor sooner rather than later. In addition to addressing the rattling problem, new windows can also help address issues associated with old windows, which include drafts and difficult operation. Investing in ENERGY STAR®-certified replacement windows can also help reduce your cooling and heating costs as well as make your home quieter and more comfortable.
There are also temporary fixes that can help reduce rattling. Loose panels can be set back into the sashes by reapplying caulk and/or by adjusting the window hardware. Old weatherstripping can be removed and replaced with new ones, which can be purchased easily at most hardware stores. It is important to note that these fixes are merely temporary. While they help address the rattling problem, you will eventually need new windows that will address the underlying problems described above.
