Window Rattling: Common Causes and Solutions

Your windows complete the look of your home and help keep your living space comfortable. They also offer protection against the elements. These are among the many reasons to keep them in good condition. 

One window problem you should look out for is rattling. Sometimes, it’s a sign that you need replacement windows. Read on to learn more. 

What Causes Windows to Rattle?

Worn-Out Weatherstripping

Weatherstripping seals gaps around windows, preventing conditioned air from escaping your home. Like other window components, they can get worn out over time. When this happens, your windows can rattle. You can secure your windows and keep them airtight with new weatherstripping. Keep in mind that various weatherstripping products are available on the market. Speak to professionals if you’re unsure which one to use. 

Loose Sash

Wood window frames tend to expand and contract with temperature changes. Over time, it can cause windows to no longer fit in their tracks. You can fix this issue by applying weatherstripping. However, if weatherstripping doesn’t resolve the problem, consult a wood window installation expert.

Loose Glass

A window can rattle if its glass is loose. Applying caulk on gaps and cracks between the glass and sash can fix the problem. You can wipe excess caulk with a cloth soaked in vinegar. 

Compromised Mortise Plate

The mortise plate keeps your windows secure while they are closed. When it gets loose, your windows won’t close properly. Removing and refitting this component can keep your windows from rattling. 

When Is a Window Replacement Necessary?

Sometimes, repairs are not enough to fix a rattling window. If your windows are severely damaged or difficult to operate, it may be time to replace them. High-quality units will strengthen your home’s defense against the elements. Many of today’s windows also come with energy-efficient features that can help keep your living space cool in summer and warm in winter. When installed correctly, new windows can improve your property’s safety and curb appeal.
