Sound sneaks into your home through openings, crevices, and through your windows and can result in restless nights. Windows, in particular bigger, older windows, are one of the main sources source of sound disturbing your home, and if you soundproof your windows you can drastically cut back on unwanted noise.

These are some things that San Antonio residents can do to soundproof your windows and lessen noise from outdoors.

Add weatherstripping or caulk to the window frame

Adding caulk or weatherstripping is an affordable DIY solution to soundproof your windows. Since air carries sound waves easily, blocking any cracks or openings by your windows will reduce noise. One thing you can do is add foam tape to the sides of your window sashes. For a double-hung window or a sliding door you can use vinyl v-strips on the outer sides of the windows. You can also caulk the crevices around windows and over any splits to stop airflow.

One downside of this do it yourself solution is that it’s more of a short-term solution, and it might damper how good your windows look.

Add sturdier window treatments like plantation shutters

installing heavy material such as San Antonio’s best plantation shutters can help block outside noise.

Plantation shutters are an eye-pleasing way to block the noise entering your home while also saving you energy. Polywood plantation shutters have a patented built-in weatherstripping design that blocks out air, temperature, and noise.


Polywood faux wood shutters are durable, so they have more longevity those DIY solutions. They are more affordable than installing new windows, and after they’re put in are a permanent part of your home, which can up your home’s sale value on the market.

Get a sound-proofing plug

If you experience constant noise like traffic near the highway you could benefit from a sound-proofing plug. This DIY option is a straight piece of foam that you slide into the gap around your window. As the foam blocks light (and can look awkward), people use sound plugs in the evening or if they really need them for a short period of time.

Replace or put in additional windows

If your windows are older and you experience draftiness as well as unwanted outside sounds, it could be time to think about replacing your windows. If you don’t have the budget to buy all new windows for every room, you can install exterior storm windows or another window pane to especially noticeable windows. The drawback is that replacing your windows or adding extra panes can still be a pricey option.
