Insulation Installed in Interior Wall

NW 58th St near 8th Ave NW, Seattle WA

Description

I’m looking to get insulation sprayed into an interior wall that splits two units in my duplex to help reduce the sound between units. Right now I do not believe there is any insulation in the wall and the wall needing insulation is about 115–150 SQFT. We would not be able to remove the drywall on the wall so I’m looking for services that offer cutting holes at the top of the wall and using an insulation hose to fill the wall with sound proofing insulation. I can patch and fix the holes left by the insulation hose myself and just need the insulation services. Please let me know your experience with this work, the process you follow, insulation type, and cost estimate. I’m available by email or text. Thanks!
