The Ultimate Guide to Soundproofing Windows and Doors

Double Pain window install

Your windows can let in outdoor noise, and doors are nefarious culprits just the same, destroying your tranquility in an instant when you hear your neighbor’s conversations or disruptive traffic. Soundproofing windows and doors can be done by you or a professional.

You need soundproofing to reclaim your peace. Fortunately, you’re in the right place! This guide to window and door soundproofing will lay out practical, actionable tips to help you bask in the silence.

Top Soundproofing Window and Door Products to Consider

You’re gung-ho about a quieter house, but soundproofing solitude begins with the right materials. Here are some that belong on your shopping list.

Acoustic Caulk

Why use traditional caulk to seal openings around windows and doors when there’s acoustic caulk instead? It goes on the same as the traditional stuff, but it features a latex base instead of silicone.

The difference? Acoustic caulk won’t harden. It’s not mushy or gooey but flexible to provide a longer lifespan and more soundproofing efficiency.

Better yet, it’s not more expensive than regular caulk, with a tube going for $9 to $25.

Soundproofing Curtains or Blinds

A set of soundproofing curtains for the windows will limit high-frequency sounds from bleeding in, including the rushing of cars outside your home.

The sound-controlling materials used to make the curtains look the same as any traditional set but can absorb sound, preventing it from bouncing around a room.

Noise-reducing blinds also have sound-absorbing abilities due to their honeycomb shape. This provides a temporary form of insulation, as the air pockets in the honeycomb structure and the fabric of the blinds work together to reduce sound wave distance.

Installing these window solutions is easy. Noise-canceling curtains cost $45 to $100, while soundproofing blinds are between $25 and $100.


One of the cheapest, simplest, and fastest ways of soundproofing windows and doors is to replace or upgrade the weatherstripping.

Weatherstripping is available in various types, from reinforced foam to door-bottom weatherstrips, tape, and door snakes or sweeps. Although weatherstripping is more synonymous with doors, you can use some types for windows.

Depending on the weatherstripping you choose, its price ranges from $5 to $55.

Soundproofing Paint 

You can always paint a door and window frame with soundproofing paint. This sound deadener features ingredients such as ceramic micro-spheres that absorb sound. The paint goes on as any other.

For best results, consider painting the surrounding walls, as soundproofing paint is only moderately effective at blocking out noise. A gallon jug costs around $55 due to the unique formula.

Soundproofing Windows

From sash to picture, bay, double-hung, sliding, and casement, windows come in an array of styles. Whether yours are brand-new or have been in the house for as many years as you’ve lived in it, you can soundproof your windows today.

Here’s how.

Installing Double-Pane Windows or Laminated Glass

For the longest time, single-pane windows were the trend, as they were inexpensive to manufacture.

However, single-pane windows also shatter more easily. More importantly, for your purposes, they let air out and in.

Indoor air leaving your home means you’re wasting your heating and air conditioning, as your home won’t easily reach optimal temperature.

When outside air comes in, it brings with it noise. That’s why double-pane windows are the new standard from dual perspectives: environmental friendliness and soundproofing.

Laminated glass is in a similar vein. This is another style of dual-paned window sealed via interlayers. The two panes of glass operate as one, including when broken.

The laminated glass is insulated to keep more inside noises out.

Applying Window Inserts

Curtail that unwanted outside noise with window inserts.

The most popular style is compression tubing inserts, which are custom-built to match your window wells’ size. Installing the window inserts limits how much sound can enter your home and provides better insulation.

Here are some DIY window soundproofing tips to assist you:

  • When glazing your windows, use acoustic glazing for maximum sound resistance.
  • Apply a self-adhesive foam seal strip around old, drafty, single-pane windows.
  • Cut an acoustic foam mat to fit the size of your window. It’s cheap, easy to install, and will add privacy by blocking sunlight. 

Soundproofing Doors

Not all doors are soundproofed the same. If yours isn’t built from fiberglass or steel, it won’t block sound as efficiently.

More so than merely the materials, the structure of the door also affects its soundproofing capabilities. Thicker, heavier, solid-core doors provide much more noise-blocking potential than a lightweight, hollow door.

If yours is the latter but you’re hesitant to rip out what’s otherwise a perfectly good door, try these soundproofing techniques.

Replacing Hollow-Core Doors with Solid-Core Doors

You can tell if your door is hollow by its weight. If it opens easily and has no give, it’s likely got a hollow core.

Upgrading to a solid-core door will do wonders for your peace of mind. You can rest assured that it’s tougher to breach a solid-core door (although by no means impossible) than a hollow door.

You also have a tougher line of defense against street noise and loud neighbors. No more barking dogs!

Applying Door Sweeps

Door sweeps are like a more sophisticated version of door snakes. They go underneath the door and create a practically airtight seal. Air can’t get in or out.

You will notice less outside noise. Closing the door when running your heater or air conditioner will also create a much warmer or cooler room faster.

Adding Soundproofing Blankets or Panels

Decorate your door with soundproofing panels or blankets. The same foam panels you used for your windows are applicable for doors. You can also adhere some blankets to the door, but make sure the blanket isn’t so large to prevent the door from opening or closing.

Try these handy tips as you plan your DIY door soundproofing:

  • Use thicker blankets to create more mass and more effectively block out sound.
  • Try expanding plugs if you can’t find acoustic caulk or can’t use caulk for the doorframe.
  • If you have a hollow door and can’t afford a replacement, you can always fill the door with dry play sand. You can cut open the plywood and then glue it back into place.

Hiring Professionals

However, if you feel like these tasks are above your pay grade (figuratively, of course), that’s more than okay. You don’t have to tinker with doors and windows, possibly voiding your warranty, when you can hire soundproofing professionals.

Finding reputable, high-quality pros begins with doing your due diligence. Research the company’s website, then expand your search to social media and home improvement sites. The contractors should have a good reputation if they’re worth hiring.

Once you find several viable contractors, request free quotes. The cheapest contractor isn’t necessarily the best, just as you don’t always have to hire the most expensive service.

Instead, set a budget before you begin and select the contractor who provides the services you seek at a price you can afford.

Wrapping Up

Soundproofing your windows and doors can make a noticeable difference in how quiet and enjoyable day-to-day life is in your home.

With so many low-cost and DIY strategies available for dampening noise, you can take the first step toward a well-soundproofed home whether you have a sky-high or shoestring budget.
