Magnolia Soundproofing — Done Right.
Magnolia is quieter than most of Seattle, but homes near Interbay, the BNSF tracks, or the Magnolia Bridge still hear the city. Our soundproofing work focuses on master bedrooms, home offices, and media rooms in these otherwise peaceful neighborhoods.
Real acoustic isolation requires four principles: mass, decoupling, damping, and sealing. Jensen Contracting has been designing soundproofing systems for Seattle-area homes for decades — and we bring that expertise to every project in Magnolia.
What We Soundproof
Common Magnolia soundproofing projects we handle every month.
Walls, Floors & Ceilings
Critical for shared-wall townhomes, duplexes, ADUs, and stacked apartments. We use mass-loaded vinyl, green glue, resilient channels, and double-stud assemblies to measurably reduce decibel transfer — not just "sound a little quieter."
Home Studios & Media Rooms
If you record music, podcasts, or stream professionally from a Magnolia home — or just want a theater room that doesn't wake the house — we build purpose-designed rooms with proper isolation clips, mass, and sealing.
Doors & Windows
Often the weakest link in any soundproofing project. We upgrade doors with solid-core cores, acoustic gaskets, and threshold seals; and add laminated-glass or interior inserts to existing windows for measurable street-noise reduction.
