5 Solutions to Stop Your Windows from Rattling

Updated: 5 days ago

Rattling windows can be very annoying; anyone who has ever had this issue will be able to tell you. However, it is hard to ignore in windy weather or if heavy vehicles pass.

Another big issue you will encounter with windows that rattle is energy loss. As well as causing drafts, it allows heat to escape meaning your energy bills will continue to rise unless you resolve the issue.

Why Do Your Windows Rattle?

Several issues cause your windows to rattle, but ultimately, it will come down to a loose frame or loose glass. To help you stop your windows rattling, below are some of our top tips and solutions.

How To Fix Rattling Windows

Taking some time to investigate your rattling windows will help you resolve the issue. Here are some of the main reasons this can happen and the solutions to stop your window rattling.

Fixing a loose pain in the window

A loose glass pane can be caused by regular use loosening the window glass over time. The best way to secure the glass is by caulking it up. Using caulk will help ensure the glass pane is in place and stop rattling. You can apply caulk by using a putty knife to apply it along all the edges of the window. When all the cracks are filled, you will be able to wipe away any excess caulk from the glass by using a cloth and vinegar. It is best to allow around 8 hours for the caulk to dry, so avoid using the window at this time. Using a silicone-based window caulk will not only stop them from rattling but will also create a waterproof seal that will stop rainwater from getting into your frames and causing further issues down the line.

Fixing a loose sash window

If you have rattling sash windows, it will most likely be caused by the sash itself becoming loose and not fitting its track. This can be caused by regular use or exposure to the elements over the years. You should check your sash windows for any signs of rot or damaged parts. If there is no rotting or damage, or you can easily replace damaged parts, removing and refitting the loose sash window should set it back into the track and resolve the rattling.

Repairing rotten wood

Wood windows have to be well maintained to perform as they should. If rainwater is allowed to soak into the timber, it can soften, rot, and change shape. Regularly checking and sealing the outside of wooden windows can help to prevent issues from taking place. Still, if you find that your wooden window frame suffers from moisture damage and is severely compromised, you will have to take action. Remove the rotten parts and any damaged or warped timber before repainting glossy or latex paint. This will be more durable against the elements.

It is best to use a chisel to remove the rotted wood and clean away debris. It would be best if you then drilled holes, roughly an inch apart, into the wood before filling with two coats of wood hardener. When the wood hardener has dried, you will use wood filler. Mold it into the frame’s shape using a putty knife and allow it to dry. Smooth this surface out with sandpaper before painting. You should scrape away old loose or cracking paint and sand the original window frame in preparation before painting. Ensure the recently treated section and the original window frame match in terms of colour before allowing the paint to dry. This may need more than one coat.

Weather-stripping your windows

Another great way to stop your windows rattling and increase your home’s energy efficiency is by weather-stripping your windows. This is a reasonably straightforward process and can be done by cleaning and drying the window pane, cutting the foam into a suitable length before peeling off the backing strip, and pressing the adhesive into place. It is an excellent option for double-hung or casement or sliding windows. Sealing any gaps on the window sash will help hold the window in place, stop rattling, and prevent warm air from escaping or cold air from entering the home.

When Should I Consider Replacement Windows?

Modern windows should have a lifespan of around 15-20 years. However, well-maintained windows that are regularly cared for will stand a much better chance of lasting longer.

However, despite all the hard work you have put in, there will come a time when window replacement is inevitable. You should probably consider replacing your old windows if you have noticed a rotten frame affecting more than 10% of the wood.

Loose glass panes or a rattling window signify that something has gone wrong. Exploring whether you will fix it might put off a significant expenditure, but constant window repairs can sometimes be a case of throwing good money after bad.

While new windows can be expensive, they will also be an opportunity to freshen up the look of your home, improve your energy efficiency, and save money on power bills and regular maintenance that old windows will need to work efficiently.
