Quick answer
How much does soundproofing drywall cost in Maryland?
Double board with a damping compound between the layers runs $3.80 to $6.50 per square foot in 2026, and adding decoupling on top of that is another $1.60 to $3.20. A single bedroom party wall typically lands at $1,400 to $3,400. A ceiling costs more than a wall at $4.20 to $7.50 because of the overhead work and the heavier assembly.
The work
What soundproofing actually involves.
Sound gets through a wall three ways: it vibrates the structure, it leaks through gaps, and it travels around the wall entirely through floors, ducts and the ceiling cavity. A soundproofing job that only addresses the first one is the usual disappointment — thicker board on the same studs is a small improvement at a real cost.
What works is some combination of three things. Mass, meaning a second layer of board, because sound has to move the wall and a heavier wall moves less. Decoupling, meaning the two faces of the wall no longer share a rigid path — resilient channel, a staggered or double stud, or clips. And damping, meaning a viscoelastic compound between two board layers that turns vibration into a small amount of heat instead of passing it on.
The honest part is what none of that fixes. Low frequencies — a subwoofer, a drum kit, a bass guitar — barely notice a drywall assembly, and we will say so before you spend money. Doors, outlets, recessed lights and shared ductwork are leaks that will cap whatever the wall achieves. We do not quote an STC figure for a finished retrofit, because the number on a product datasheet was measured in a lab on an assembly with no doors, no outlets and no floor joists running through it.

Honest about the limits
What soundproofing costs in Maryland
Priced per square foot of treated wall or ceiling, over and above a standard hang. Decoupling costs more than mass, and both cost less than regretting a single-layer attempt.

What’s included
Everything the soundproofing scope actually covers.
Written into the estimate, not assumed. If something on your job is not on this list, it gets priced and named before anyone starts.
The assembly chosen for the problem
01A teenager's stereo, a home office on a party wall and a nursery under a hallway are three different problems. We ask what the sound is before specifying what the wall is.
Double board with damping compound
02Two layers with a viscoelastic layer between, which is the single most cost-effective step on most walls — far more than one thicker sheet.
Decoupling where the structure allows
03Resilient channel or clips and hat track, so the board no longer has a rigid path to the framing. Not possible in every retrofit, and we will say when it is not.
Flanking paths addressed
04Outlets backed and sealed, can lights reconsidered, duct boots treated, and the wall carried tight to the deck rather than stopping at the ceiling line.
Acoustic sealant at every perimeter
05A continuous bead at floor, ceiling and both ends. An unsealed quarter-inch gap at the bottom of a wall undoes most of what the layers above it bought.
A realistic expectation in writing
06What you will notice, what you will still hear, and which remaining path is the cap. Written down before we start rather than explained afterwards.

Soundproofing questions

Mostly, within limits worth knowing. On speech, television and general household noise through a wall, a damped double-layer assembly makes a difference you will clearly notice. On low frequencies — bass, drums, a subwoofer — the improvement is small, because long wavelengths move a drywall wall whatever it is made of. And the result is capped by the weakest path in the room, which is often a hollow door or a shared duct rather than the wall at all.
It is the option people ask for and the one we would steer away from. A single heavier sheet adds mass but keeps the rigid path to the studs, so the gain is modest for the price of specialty board. Two layers of ordinary board with damping compound between them costs about the same and performs considerably better. If budget only allows one step, that is the one to take.
Yes, by building onto the existing finished wall — clips and channel, then two damped layers over the top. You lose roughly two inches of room and the trim has to be reworked, but no demolition is needed and the mess is far smaller. Where the wall is already open for other work, treating the cavity and decoupling the framing gets you more for less, so sequence matters.
