As you already know, soundproof doors are the most powerful soldiers against outside noise. But how much does a soundproof door cost, and what factors influence its price?

These things are really important to know to make a decision that you won’t regret later. So yeah, we guys are here to give you all the information related to a soundproof door price.

We’ll cover everything, from factors affecting its price to how much does it cost to soundproof a door. Let’s dive in and get all your questions answered.

How much do soundproof doors cost?

A soundproof door can cost anywhere from $500 for basic ones to over $5,000 for high-end, custom options. But as you all know, this price heavily depends on a lot of factors. So now, let’s explore the factors that have a big impact on how much you’ll pay for a soundproof door

Factors affecting the cost of a soundproof door

Here is the breakdown of the factors in which the cost of a soundproof door rely on:

1: Size of the door

This size of soundproof you will need is the most oblivious factor, the bigger the door you will need  the bigger the cost will be, it’s a simple equation.

When you buy a door, you’re not just paying for the door itself but also the materials used to make it. Larger doors require more materials, which naturally makes them more expensive. 

2: Material and its quality

The materials and the quality of that materials that is used to make that soundproof door is the second deciding aspect of its cost. Different materials have different degrees of soundproofing effectiveness. 

For instance, solid and dense materials like wood and metal tend to be better at blocking sound than lightweight materials.

Furthermore, the quality of the materials is a big deal. It determines how long the door will last. As obvious, higher-quality materials are more durable and resistant to wear and tear. They are less likely to warp, crack, or deteriorate over time.

3: STC rating of the door

In my opinion, the STC rating of a soundproof door is the most important to look at. STC stands for Sound Transmission Class. It’s a rating system used to measure how effective a door (or any building element) is at blocking sound, which is why it is so important.

STC ratings fall within a range from 25 to 65 STC. The higher the STC rating, the better the door is at keeping out sound. 

Each increase of 10 points on the STC scale roughly doubles the door’s sound-blocking ability. STC rating above 35 is a good rule of thumb for soundproofing. Doors with STC ratings in the 55s or higher can cost you up to $5000.

4: Installation costs

Soundproof door might be more complex to install than a standard door, which may result in a need for a skilled professional to handle the installation task.

However, if you’re a handy DIY enthusiast and have experience with door installations then you can do it too and save the cost of hiring a pro.

Talking about their price, solid wood soundproof doors typically cost between $500 and $1,000 or more per door. The price varies based on size, material, and customization options. 

Well, you may even find a solid door under $500 but they don’t really do a great job at keeping out sound. They can’t be called true “soundproof doors.”

2: Metal Soundproof Doors:

Metal soundproof doors are prized for their combination of strength, security, and exceptional sound-blocking capabilities. 

These doors are ideal for spaces where both noise reduction and robust security are top priorities.
