How to Repair Rattling Windows

As the weather cools down and the wind picks up, you may notice your windows rattling more. The sound itself can be a nuisance, but it’s also a sign that your window needs repaired.

Loose Window Glass

Many single-pane windows have been set in the frame using putty. As the putty shrinks over time, the glass can become loose and vibrate when hit by the wind.

How do you fix it?

Apply a fresh application of caulk for a short-term solution. This will only last for a few months, so you if you want a long-term answer, learn about our replacement windows. They provide superior performance and come with a 20-year warranty for Fibrex® and glass.

Loose Sashes

Window frames and sashes can become warped from temperature changes or loosen due to old, damaged hardware, causing it to not fit properly in the track.

How do you fix it?

Replace the hardware on your sashes to fix the looseness and prevent rattling; however, this solution won’t fix structural issues such as warping. In that case, it’s best to replace your windows with long-lasting materials. We use composite Fibrex® material for our frames and sashes, which is less prone to warping.

Worn-out Weatherstripping

Weatherstripping protects the gaps between window sashes and frames to reduce air leaks, and it can get worn out over time, which may result in rattling windows.

How do you fix it?

Replace it! Rubber weatherstripping is easy to replace yourself, but if you have metal weatherstripping, it’s best to call a professional to get an airtight fit. If you have Renewal by Andersen windows, call us! Our windows come with a 10-year limited warranty on weatherstripping.

Wood Rot

If not properly maintained, wood windows can deteriorate from moisture damage. The wood will rot, and the sash will not fit properly in the frame, resulting in rattling and gaps that allow air inside your home and cause a loss of energy.

How do you fix it?

If you catch the rot early, it can be repaired with a wood filler or putty; however, these fixes aren’t always enough. Once your window shows extensive damage, a window replacement is the best long-term solution. Learn how our windows are engineered for superior performance and energy-efficiency.
