Northstar Specialties, Inc. installs both gypsum and self-leveling, cementitious underlayments. Gypsum underlayments are ideal for adding fire resistance and sound control to wood frame, multifamily construction. For rough, spalled concrete, we can install Level-Right Self-Leveling Underlayments from a featheredge, providing a smooth, durable new surface.
With our state-of-the-art equipment, underlayments install quickly, and they can be walked on in as little as 2 to 4 hours after the pour, keeping your project on track.
