Why Do Your Windows Rattle? Tips and Solutions to Prevent This

Here at South Coast, we know the importance of a well-fitted, high quality sash window, and we understand the frustration that comes when one of your windows starts to rattle. They can become expensive over time, as gaps can allow cold air into your home and affect your energy bills when your windows rattle in the wind, and it can also be annoying to have to listen to every day.

However, the exasperation that comes with rattling windows is not the only reason they need to be fixed. The rattling may be a sign of an underlying problem, which may require a more thorough solution.

There are several methods you can use to stop rattling windows, with various reasons behind the cause in the first place.

There is a Loose Glass Pane in the Window

One of the two most common reasons for windows rattling is that a window pane is loose. If this is the case, you will need to apply caulk to the affected glass. Putting caulk into the cracks between the window and the frame holds the glass in place, sealing any gaps and making it airtight.

To do this, use a putty knife to work the caulk into the deepest and hardest-to-reach areas, making sure that everywhere is sealed. After you have finished sealing the cracks, wipe off excess caulk from the frames and your windows using a rag soaked in vinegar.

The Sash is Loose

The other most common reason for rattling sash windows is that the sash itself is loose. This may happen over time as your windows are exposed to the elements, growing weaker as the years pass and becoming damaged. This may result in the window not fitting properly in its track.

It is possible to fix this issue yourself if you have experience in DIY and home improvements and repairs. However, it is always best to call the professionals for advice, if you want to be sure that your methods are working. We are highly qualified and experienced in our industry and we will be happy to help you make the best decision to fix your rattling windows. Get in touch and let us advise.

The Mortice Plate Needs to be Adjusted

Mortice plates are the catches you use to secure your windows when they are shut. If they end up damaged or becoming loose themselves, the window may not close properly and will rattle. To stop your sash windows rattling because of this, remove the plate and fit it again. If it is fitted properly, the rattling should stop.

This can be a difficult procedure to carry out if you are unfamiliar with how to properly dismantle, fix and put parts of a window back together.

You Might Need to Weather-Strip Your Windows

Weather-stripping is a process in which your windows are sealed, usually with material such as adhesive backed foam, to prevent rain and other excess water from entering your home. Instead, it gets rerouted or returned. This method will stop windows rattling in the wind and warm air in your home will also not be lost, as sealing the cracks will prevent heat from escaping.

You May Need to Have Your Windows Replaced

There is not always a quick fix for rattling windows, and even if one can be found for your window, this may simply be delaying the inevitable. Consistently fixing problems could end up costing a homeowner more money in the long term when a one-off payment will resolve the problem entirely.

Having new windows installed in place of the old ones will resolve the issue of rattling, and you will have peace of mind in knowing that the windows will take many years before they need either fixing or replacing again.
