Soundproofing an old house is a smart investment that can improve your quality of life and save you money in the long run.

Common Noise Problems In Old Houses

Old homes have several vulnerabilities that allow sound to easily travel in and out:

Thin walls and ceilings – Plaster and lath wall assemblies have very little insulation. Noise easily transmits through to adjacent rooms.

No noise buffers – Modern homes have flooring insulation and acoustic caulking that old homes lack. There are no sound barriers.

Poorly sealed – Gaps around windows, floors, trim and doors allow noise leaks. Draft sealing improves soundproofing.

Hollow doors – Many old wooden doors are hollow rather than solid core, providing minimal noise control.

Single pane windows – Non-insulated glass and loose frames allow exterior noise intrusion.

Creaks and vibrations – Settlement and loose floorboards create noise when walked on.

Noisy plumbing – Old pipes clank and rattle as water flows through.

These acoustic deficiencies make sound easily heard throughout the house. Neighbor and traffic noises infiltrate in. Addressing these problem areas can restore peace and quiet.

Prioritizing Soundproofing Locations

With an old house, there may be many areas that need soundproofing. Focus first on locations where noise disruption is greatest or privacy is most desirable.

Bedrooms – Blocking exterior noise and containing sounds within bedrooms should be a priority to prevent sleep disturbances.

Home office – A dedicated workspace needs acoustic isolation to improve productivity and concentration.

Media rooms – Separating movie, gaming or music spaces prevents Noise from disturbing others.

Nurseries – Infant rooms need noise buffers for naps and fussy periods.

Bathrooms – Running water can generate loud pipe rattles that echo through walls.

Targeting noise control in key rooms makes the best use of time and budget.

Simple Soundproofing For Old Houses

Many homeowners want to improve acoustics while preserving original architecture. Here are DIY-friendly methods that don’t require major demolition and repairs:

Acoustic Caulking

Sealing all seams and gaps with acoustic sealant is a fast, cheap way to soundproof an old house. It keeps noise from leaking through cracks. Acoustic caulking stays flexible when dry and won’t shrink or crack. Use around:

  • Door and window trim
  • Baseboards and crown molding
  • Electrical outlets and switches
  • HVAC vents and ducts
  • Drywall seams

Well-sealed homes are also more energy efficient.


Adding weatherstrips around doors and windows seals air gaps that easily transmit sound. Materials like felt, foam and rubber compress when the door or window closes to block noise leaks. This also helps reduce heating and cooling costs.

For extra sealing, install door sweeps on bottom gaps and thresholds. Make sure strips don’t hinder operation. Replacing exterior seals regularly preserves acoustic performance.

Area Rugs

Laying down large area rugs and carpets absorbs footsteps, provides cushioning, and blocks impact noise on hard floors throughout an old home. Use heavy padding underneath for extra sound dampening.

Rugs also reduce echo and reverberation that amplify noises in rooms with plaster walls and bare floors. Scatter smaller throw rugs to soften footfalls in heavily trafficked hallways.


Adding insulation to walls, floors and ceilings absorbs noise vibrations and blocks sound transmission between rooms when installed properly. Blown-in types like cellulose can be added through holes to minimize plaster damage:

  • Feed hose behind outlet and switch plates
  • Use existing duct work openings
  • Drill discreet holes in closets and behind furniture

Insulation also improves energy efficiency which helps offset upgrade costs.

Soundproof Blankets

Heavy quilted moving blankets make an inexpensive sound barrier when hung on walls. The dense layered fabric helps dampen noise from adjacent rooms or the exterior. Install blankets using adhesive hook tape, removable panel clips or nails.

Handy homeowners can sew custom soundproofing blankets using upholstery-weight fabric and insulating batting. Tacks or removable hooks allow these blankets to be mounted temporarily as needed.

Acoustic Foam Panels

Self-adhesive foam acoustic tiles attach easily to walls and ceilings to absorb sound rather than block it. The porous surface deadens echo and dampens noises within a room. Panels come in basic wedge shapes or decorative patterns.

Foam tiles are lightweight and easier to install than rigid fiberglass panels. They are less effective at preventing noise transmission but improve room acoustics. Use 2-inch or thicker tiles for noticeable results.

Draft Stoppers

Plugging gaps beneath doors with rolled-up towels is an almost-free fix for major noise leaks in old homes. To make this solution semi-permanent, install slide-on draft stop pads or door sweeps to seal the entire bottom edge.

Adhesive foam strips that stick onto door and window frames to block air movement also quiet sound leaks. Draft stoppers improve energy efficiency too.

Advanced Soundproofing For Older Homes

The methods below require more extensive work and cash, but deliver superior acoustic control:

Sound Clips/Resilient Channels

Installing sound clips or resilient channels (RC) creates an air gap that decouples drywall from framing studs for less sound transmission. The zigzag RC or clip design isolates wall surfaces to dampen noise.

Drywall is attached to the clips instead of being screwed directly into studs. Clips can be retrofitted onto existing walls while channels require removing drywall. Channels also work well on ceilings.

Double Stud Walls

Building a new stud wall inside an existing wall leaves an air gap that prevents noise transfer through framing. Drywall is attached to the new inner wall. Both wall surfaces are insulated for better sound absorption.

If room size permits, building a double stud wall is one of the most effective soundproofing retrofits. It requires refinishing trims but avoids exterior wall demolition.

Soundproof Drywall

Using multiple layers or special noise-reducing drywall improves sound isolation between rooms when installed on old wood lath walls or directly over plaster. Staggering seams between layers reduces sound leaks.

Products like QuietRock with extra dense cores block more noise than regular drywall. Green glue adhesive used between drywall sheets contains damping compounds for better soundproofing.

Sealed Attic Insulation

Blown-in cellulose or fiberglass insulation in attic spaces helps muffle overhead noise if the material is effectively contained. Sealing any ceiling cracks or gaps first is crucial to prevent sound leaks into rooms below.

Creating baffles around ceiling fixtures, wires and pipes maintains an air buffer that keeps insulation from settling. This improves noise reduction and energy savings.

Soundproof Exterior Windows

Replacing thin single pane windows with thick, multi-layered glass models provides much better sound insulation. New sashes seal tighter and reduce outdoor noise like traffic. Storm windows added to existing frames is a less expensive retrofit option.

If window replacement isn’t possible, install heavy soundproof curtains to dampen noise intrusion. Make sure they form an airtight seal around frames when closed.

Soundproof Doors

Solid core wood or heavy insulated metal doors block more noise than hollow old doors with loose-fitting frames. Sealing the perimeter gaps and undercutting gaps at the base of doors also prevents sound leaks.

For simpler upgrades, adding thick weatherstripping and replacing hollow core doors with solid models improves acoustic control between rooms without major framing modifications.

Soundproofing An Old House FAQs

How much does it cost to soundproof an old house?

Basic DIY improvements with caulk, rugs, and foam can cost as little as $200-500. Hiring contractors for major upgrades like redoing walls and ceilings can run $3,000-$10,000 depending on house size.

What are the best soundproofing materials for old homes?

Sealing cracks, weatherstripping, insulation, double drywall, resilient channels/clips, solid core doors and soundproof windows provide the best noise reduction. Lightweight acoustic foam and rugs also help but focus more on sound absorption.

Should exterior walls or interior walls be soundproofed first?

Prioritize interior walls between bedrooms, media rooms and home offices to improve sleep and concentration. Exterior wall soundproofing to block outdoor noise can come later.

Do acoustic panels work for soundproofing old homes?

Foam panels don’t block sound as well as weatherstripping and caulk, but they help absorb echo and reverberation to improve interior acoustics. Use them in combination with sealing methods.

Can blown-in insulation be added to existing finished walls?

With some careful prep work, cellulose and fiberglass insulation can be blown into wall cavities through small holes to maintain appearance. Take care not to over-pack walls and density will be inconsistent.
