Joint compound removed from a shared townhome wall before soundproofing
Example project
- Home
- Late-1970s two-story townhome in Eden Prairie, sharing one side wall with the next unit
- Original request
- Open the shared wall on both floors, add sound insulation and hang two layers of new drywall
- Testing
- Samples of the joint compound, the drywall and the wall texture on both floors by an MDH-certified inspector
- Found
- The taped seams on the shared wall have asbestos in their joint compound
- Clear
- No asbestos in the drywall board or the wall texture
- Area
- About 320 sq ft of wall, living room and main bedroom
- Timeline
- Five-day notice, then three working days
- Cost
- $3,650
In this example, the owner of a late-1970s townhome in Eden Prairie hears too much through the shared wall. A soundproofing contractor will strip the shared wall on the owner’s side, on both floors, and rebuild it with insulation and a double layer of drywall.
