How Much Does It Cost to Soundproof a Room?

By the HomePriceFacts Research Team · Last updated: November 14, 2026 · Prices checked against published 2026 soundproofing cost data

Soundproofing a room costs $1,036 to $2,743 in 2026 — and the reason quotes for the same room swing across that whole range is that "soundproofing" means different things to different bidders. One quote covers acoustic panels on two walls. Another covers opening every wall, adding insulation and mass-loaded vinyl, hanging a second layer of drywall, replacing the door and sealing the windows. Both are honest quotes for different jobs, which is why this guide prices the work per square foot, per surface and per room type, and shows exactly where the two biggest cost publishers — Angi and HomeGuide — agree and where they measure different scopes.

The first thing to understand is what soundproofing actually does, because the price only makes sense once the physics is clear. Soundproofing does two different jobs that get sold under one name. Sound absorption — foam panels, acoustic tiles, curtains, rugs — soaks up echo inside the room and makes it sound better, but it barely stops sound leaving or entering. Sound blocking — mass, airtight sealing and decoupling — stops sound travelling through the structure, and it is the expensive part: extra drywall, mass-loaded vinyl, insulation in the cavities, a solid-core door, sealed windows. A room that only needs to sound better for video calls can be fixed for a few hundred dollars of panels. A room that must not leak drum practice into the nursery needs the full blocking treatment, and that is where the $10–$30 per square foot band comes from. Both sources are explicit that the per-square-foot figure applies to the treated surface area, not the room's floor area — a 12' x 12' room has roughly 500 square feet of wall plus ceiling to treat, which is why a "small room" quote can still reach four figures.

The second thing to know is that the two publishers' headline numbers are both real and both useful, once you know what each one counts. Angi's guide, updated September 22, 2026, prices the installed job at $1,036–$2,743 with a $1,881 average across 194 verified projects from Angi Pros. HomeGuide's guide, updated November 5, 2025, prices the same job at $1,400–$4,300 on average and $1,000–$9,000 in total, with materials at $200–$5,100 and labour at $800–$3,900 for a 100–300 square foot room. The overlap at the bottom — both start near $1,000–$1,400 — is the single-room wall-and-door job. The divergence at the top is the isolation job: HomeGuide prices the decoupled, every-surface work that Angi's average project never touches. Neither source is wrong; they are answering slightly different questions, and this guide keeps them separate so you can see which one matches your room.

What the price normally includes

• Acoustic wall panels or textured panels — $1.50–$5 per square foot (Angi); acoustic panels $2–$17 per square foot (HomeGuide)
• Insulation in wall cavities — foam $1–$3 per square foot, spray foam $1.50–$5.00 per square foot, blown-in fiberglass $1.00–$2.80 per square foot
• Mass-loaded vinyl barrier — $2–$5 per square foot (Angi); $3–$5 per square foot (HomeGuide)
• Soundproof drywall — $40 per panel (Angi); $30–$100 per 4' x 8' panel for materials, $2–$7 per square foot installed (HomeGuide)
• Door treatment — sweeps and seals from $10, up to $1,000+ for a solid-core or acoustic door (Angi); $50–$1,600 total (HomeGuide)
• Window treatment — acoustic curtains $20–$400, inserts or secondary glazing, up to $1,500+ per window (Angi); new soundproof window $550–$2,000 installed (HomeGuide)
• Floor treatment — acoustic underlayment and mass-loaded vinyl, $2–$8 per square foot; carpet $2–$8 per square foot installed (HomeGuide)
• Labour — around $300 for a straightforward retrofit (Angi); $250–$500 for a pro on simple work, or $8–$13 per square foot (HomeGuide)
• Removal and disposal of existing drywall or insulation — $100–$800 (Angi)
• NOT usually included: new wall framing ($25–$65 per linear foot), a decoupled room-within-a-room build, HVAC silencing, or permits where your city requires them

Soundproofing cost by room size

Angi's size table is the $10–$30 per square foot band applied to treated area, and it is the most useful planning tool on either source — but read it with the treated-area warning in mind. The "50 sq ft" row is not a 50-square-foot room; it is 50 square feet of treated surface, roughly one wall of a small bedroom. A full 12' x 12' room treated on all four walls and the ceiling is closer to 600 square feet of surface, which is why a whole-room job lands at $1,881 on Angi's average rather than at the $1,000–$3,000 the 100-square-foot row suggests. One row of Angi's own table is left out of this guide: its 300-square-foot row lists $3,000–$5,000, which contradicts its own $10–$30 per square foot band (which implies $3,000–$9,000) and the pattern of every row above it. It looks like a data error in the source, so it is excluded rather than repeated. HomeGuide's single-wall figure is the useful cross-check at this scale: soundproofing one 12' x 8' wall averages $960 to $2,900, which is $10–$30 per square foot on 96 square feet — the same band, measured a different way.

Soundproofing cost by room type

Room type matters more than room size, because it decides which surfaces get treated and how far the treatment goes. A home office is the cheapest job on Angi's table at $100–$1,000: the goal is usually intelligibility on calls, not isolation, so door seals, weatherstripping and a few panels do it. A bedroom at $300–$1,500 is the most common job — small, one door, mostly walls — and the price splits cleanly between panels at the bottom and opened-up wall insulation at the top. A basement at $300–$2,000 is cheap for its size because concrete walls already block a lot of sound; the money goes into the ceiling, where the floor joists above carry footfall straight through. The living room at $1,000–$7,500 and the home theater at $1,000–$10,000 are the expensive end for the same reason: big open volumes, high ceilings, and — for a theater — every surface treated and decoupled, which is the work that pushes a project into HomeGuide's $9,000 territory. Our basement finishing cost guide prices the room these treatments most often land in, and our golf simulator cost guide covers the other room that gets fully treated — a simulator room needs the same wall and ceiling work, for the same reason.

Soundproofing cost by surface

Walls are the cheapest surface to treat and the first one to treat: $1–$10 per square foot on Angi's figures, depending on whether the answer is panels hung on the surface or insulation and vinyl inside the wall. That is also why a single wall is the most common starter job — HomeGuide's $960–$2,900 for one 12' x 8' wall is the price of the shared wall with the noisy neighbour, done properly. Ceilings are the next most expensive surface at $5–$20 per square foot, because the work is overhead, often means a second drywall layer or a drop-ceiling grid, and acoustic tile alone runs about $10 a tile on Angi's figures. Floors are the cheapest structural surface at $2–$8 per square foot — high-density carpet padding, acoustic underlayment or a vinyl layer under the finish — and a rug is the only treatment that needs no contractor at all. Doors and windows are where the per-unit price jumps: a hollow-core door is a hole in any soundproofing plan, and the fix runs from a $10 door sweep to $1,000+ for a solid-core or acoustic replacement, while a window runs from $15–$100 of acoustic caulk (HomeGuide) to a $550–$2,000 new soundproof window installed. The practical rule both sources imply is to treat the surface that transmits the most noise in your specific room first — usually the shared wall, then the door, then the window — rather than spreading a thin budget evenly over every surface.

Soundproofing material prices

The material table is where the two sources' different ways of measuring show up most clearly, and it is also where the cheapest path is visible. Foam insulation injected into a wall cavity at $1–$3 per square foot is the cheapest real blocking material on either source, and it has the advantage of not needing the drywall removed. Textured wall panels at $1.50–$5 per square foot are the cheapest surface treatment, and they are the one material both sources agree is a genuine DIY job. Mass-loaded vinyl at $2–$5 per square foot is the workhorse of serious soundproofing — a dense, flexible sheet installed behind drywall or under floors — and it is the material that separates a panel job from an isolation job. Soundproof drywall is the same story told two ways: Angi prices it at $40 a panel, HomeGuide at $30–$100 per 4' x 8' panel for materials alone and $2–$7 per square foot installed, which is the same product once the panel's 32 square feet are counted. Acoustic paint is the material to skip: both sources rank it among the least effective methods, and HomeGuide prices it at $1–$4 per square foot for what is essentially thick paint. HomeGuide's practical rule for panels is worth keeping: cover at least 15% to 30% of the wall's surface area, or the panels are decoration rather than treatment.

What drives the price up or down

How much sound you need to block

Echo control and sound isolation are different budgets. Panels, tiles and curtains fix echo for a few hundred dollars. Blocking a neighbour's television, a drum kit or street traffic needs mass, sealing and decoupling on every surface, and that is the work that reaches $30 per square foot. Be honest about which problem you have before you buy anything — the most common overspend in this category is isolation-grade materials bought for an echo problem.

Existing room vs new construction

Soundproofing an existing room costs more, because the work starts with removing finished drywall or plaster to get at the cavities, at $100–$800 for removal and disposal on Angi's figures, and then rebuilding. In new construction the materials go in during framing — mineral wool in the cavities, resilient or vibration clips under floors and walls, double drywall from the start — with no demolition at all. Angi's ceiling guide makes the same point from the other side: a pro can finish a retrofit in one to two days, but the retrofit is still the expensive version of the job.

House vs condo

A house runs $10–$30 per square foot and a condo $1–$5 per square foot on Angi's figures, but the condo number is not a bargain — it is a different, lighter job. Condo work is usually loose-fill insulation or thick curtains, because the association restricts what can be changed: you cannot open a shared wall or replace a window in most buildings. Check the association's rules before budgeting, because the cheapest condo treatment is often the only one allowed.

The door and the window

Soundproofing is only as good as its weakest point, and the weakest points are almost always the door and the window. A hollow-core interior door transmits more sound than the wall beside it, which is why the door line runs from $10 for a sweep to $1,000+ for a solid-core replacement — and why a room treated on four walls but left with a hollow door still leaks. Windows are the same: acoustic caulk at $15–$100 is the cheap fix, a soundproof insert is the middle, and a new $550–$2,000 window is the expensive one. Budget the door and window before the second wall.

Labour and the pro question

Labour is the smaller share of this job than of most on this site — Angi prices a pro at around $300 for a straightforward retrofit and $250–$500 for simple work, while HomeGuide prices professional labour at $8–$13 per square foot and a handyman at $50–$80 an hour. The case for hiring a pro is not the labour cost but the failure mode: gaps, unsealed edges and penetrations around pipes and wires undo the whole treatment, and a pro knows where the leaks are. Simple tasks — hanging panels or acoustic tiles — are manageable DIY; mass-loaded vinyl, soundproof drywall and insulation inside walls are best left to a pro, on both sources' advice.

STC, and what the number means

Soundproofing materials are rated by Sound Transmission Class (STC): the higher the number, the more sound the assembly blocks. HomeGuide's rule is that highly soundproof materials have a greater STC rating, and that a room can be completely soundproofed by addressing all entry points with the right materials — but "all entry points" is doing the work in that sentence. A single untreated surface, an unsealed gap around a pipe, or a hollow door caps the whole room at the weakest link's rating. Do not buy materials on STC alone without a plan for the gaps; the sealing is what the rating assumes.

Why the two guides disagree — and what to budget

Angi's $1,881 average and HomeGuide's $1,400–$4,300 average look like a disagreement until the scopes are laid side by side. Angi's figure is built from 194 verified projects — real jobs, mostly single rooms, mostly walls and a door. HomeGuide's band is built from member-reported project costs and includes the full-isolation end of the market: home theaters at $1,000–$10,000, decoupled rooms, every surface treated. A third check supports the middle of the range: Fixr's survey, as quoted by Burton Acoustix in October 2026, puts the national average at $2,000 with an average range of $1,000–$4,000, labour at $200–$400 per room, and the same $10–$30 per square foot for an existing room against $12–$25 per square foot in new construction. Three sources, three averages — $1,881, $2,000, and a $1,400–$4,300 band — and all three agree on the $10–$30 per square foot unit price. Budget $10–$30 per square foot of treated surface, count the surfaces honestly, and the total will land inside all three sources at once.

Ways to keep the cost down

• Start with the shared wall only — HomeGuide's $960–$2,900 for one 12' x 8' wall is the highest-return single spend, and it may be all you need.
• Fix the door first — a $10 door sweep and weatherstripping close the biggest leak in the room for the price of lunch.
• Use household items for the echo: rugs, heavy curtains and blankets cost little and need no contractor (HomeGuide's cheapest route).
• Hang textured panels yourself — $1.50–$5 per square foot, easy DIY, and they cover the echo problem outright.
• Inject foam insulation instead of opening walls — $1–$3 per square foot, no drywall removal, no $100–$800 disposal bill.
• Cover 15–30% of the wall with panels (HomeGuide's rule) — full coverage is rarely needed for echo control, and it doubles the material bill.
• Skip acoustic paint — both sources rank it among the least effective methods, and the money buys real panels instead.
• Get three written quotes for the same scope, and require every bidder to list removal, materials and labour separately — a quote that omits the door and window work is not cheaper, it is incomplete.
