Estimate the Cost to Soundproof a Ceiling
Although soundproofing a ceiling is easier and more cost-effective at the building stage, you can still soundproof an existing ceiling. It’s a sizable installation job so you will want to budget for it effectively. Using a professional will drive up the costs of the project whereas taking the DIY approach will save you big bucks. Here are some things to consider when estimating the potential costs to soundproof your ceiling.
How to Soundproof the Ceiling
The goal when soundproofing a ceiling is to minimize vibration by eliminating gaps. To do this, you will need to remove the existing ceiling and fill the space between the joists with insulation and layers of drywall. You’ll also need to use special acoustical caulk to fill in any gaps.
With this all done, you should cover the ceiling with acoustical tiles which will deaden the sound even more. After this, either reuse your old drywall ceiling or fit a new one. Your new soundproof ceiling will sit just a little lower.
The cost will depend on the size of your room. The first thing to do is measure your room. This will determine how much you’ll be spending. Since you’ll be doing the work yourself, you can subtract the cost of labor. After this, make a list of the materials you’ll require. You’ll need foam insulation, with either an R13 or R12 rating in order for it to be properly effective. This is rigid foam, so it will be easy to calculate how much you need.
You’ll also need acoustic tiles to cover the entire ceiling. Again, it will be easy to figure out how much you need simply from the measurements of the room. Add onto that two layers of drywall to fit in between the joists, and one more to be the final ceiling.
The final item is the acoustic caulk. Until you open up the ceiling and discover the gaps you have, it will be difficult to judge how much of this you’ll really need.
For a room that’s 10x10-feet, you can easily calculate the costs. However, it’s worth visiting different hardware stores to check whether they have any of the items you require on sale, which can save you a lot of money.
Drywall comes in sheets that are 4x8-feet. This means that for 3 layers of drywall you should buy 10 sheets. This is a little more than you’ll need, but it allows for mistakes. At an estimated cost of $6 per sheet, that’s $60. Foam insulation also comes in 4x8-feet sheets. Estimate that you will need 10 of those. The foam should be 1-inch thick. These sheets cost $8 each, so you’ll spend $80.
Acoustical tile is generally 20x20-inches. This means you’ll need 36 tiles in total. At a cost of $10 per tile, this will come to $360. Good acoustical caulk costs around $20 per tube. Estimate 3 tubes, which comes to $60.
Now factor in $100 for other costs, such as drywall mud, adhesive, and paint. The total for this sample-size soundproof ceiling is $860.
