Drywall
Soundproofing & Acoustic Drywall in Olympia & Lacey, WA
Solis Interiors provides soundproofing and acoustic drywall in Olympia and Lacey, WA. True soundproofing requires an engineered assembly combining structural decoupling, dense mass, damping polymers, and airtight seals. Solis Interiors installs laboratory-tested acoustic drywall assemblies across Lacey, Olympia, and Tacoma for home theaters, ADUs, and private offices.

The documented noise exposure here is smaller than the base's reputation suggests
The 2015 Air Installation Compatible Use Zone study puts 579 off-base acres and roughly 2,367 people inside the 65 dB DNL contour around McChord Field, and the 75 dB contour covers 11 acres and no residents. Only Tacoma, Lakewood, and unincorporated Parkland, Midland and Spanaway fall inside the off-base 65 dB line; DuPont, Steilacoom, University Place and northeast Thurston County do not, because the noise zones south of the airfield stay on base. Where the exposure is real, it is usually a highway or a rail line rather than an aircraft, and that is the condition a wall assembly has to be built for.
Frequently asked questions
Questions & expert answers
Q1Where the state has built highway noise walls is a map of real exposure
Washington's built noise-abatement inventory records ten walls across 27,606 linear feet in Thurston County, all of them on Interstate 5 - seven in Tumwater, two in Lacey, one in Olympia - and thirteen across 19,808 feet in Pierce County on I-5, SR-16 and SR-704. Lewis County has none, and the layer carries no records at all for US-101, SR-512, SR-7 or SR-507, which means those corridors are undocumented rather than quiet. Walls were only built where measured exposure warranted them, so the inventory is a reasonable starting point for asking what a room actually sits next to.
Q2How does structural decoupling with resilient channel stop noise?
Sound travels through wall studs as physical vibration. Solis Interiors breaks this direct path using resilient isolation channels (RC-1) or sound isolation clips, mechanically decoupling drywall panels from framing so sound vibrations dissipate within the cavity.
Q3What makes constrained-layer acoustic drywall more effective?
We install high-density acoustic drywall (such as QuietRock) with internal viscoelastic polymer cores that convert sound energy into trace heat. Combined with mineral wool cavity insulation, these assemblies achieve STC ratings of 55+, blocking voices and television noise.
Q4Why is perimeter acoustic sealing critical for sound isolation?
An acoustic wall fails if air gaps remain. We apply continuous non-hardening acoustic sealant along all baseplates, top tracks, and perimeter intersections, adding acoustic putty pads around electrical boxes to eliminate sound flanking paths.
The process
Seamless execution with a smooth finish.
A short path from the first description of the problem to a clear next step.
Step 1 — Text Photos or Send Plans
Send cell photos of your wall damage or share architectural blueprints for a fast, itemized estimate.
Step 2 — Clean Prep, Zero Dust Escape
We erect zip-wall poly containment zones and run commercial HEPA dust extractors so your living spaces stay spotless.
Step 3 — Final Raking-Light Walkthrough
Before packing up, we inspect every wall and ceiling under 500W grazing lamps alongside you to guarantee 100% optical flatness.
