Bellevue Soundproofing — Done Right.
Bellevue's rapid growth means more neighbors, tighter lots, and the new I-405 and SR-520 traffic patterns. Executive homeowners increasingly ask us for home-theater soundproofing, home-studio builds, and quiet home offices.
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 Bellevue.
What We Soundproof
Common Bellevue 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 Bellevue 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.
