Step 5 · Install New Flooring or Carpet
Follow the manufacturer's instructions for installing your chosen final flooring material (e.g., carpet, hardwood, laminate). Ensure that the installation is done correctly, paying attention to proper fastening, expansion gaps (for hardwood/laminate), and seam placement. If installing carpet, ensure it is stretched properly. If installing hardwood or laminate, ensure it is installed as a floating floor over the soundproofing layers, or as recommended by the specific soundproofing material manufacturer.
