Can floor leveling be done over wood subfloors as well as concrete? This is a critical question for property owners preparing for new flooring installation or correcting uneven surfaces. The subfloor type—whether wood or concrete—plays a major role in determining the appropriate floor leveling method. Property owners must consider the structural integrity, moisture conditions, and compatibility with finishing materials. Understanding these differences helps ensure a smooth, stable, and long-lasting flooring result.

Floor Leveling for Both Wood and Concrete Subfloors

Yes, floor leveling can be successfully completed over both wood subfloors and concrete slabs, but the materials and methods differ slightly for each. On concrete, self-leveling underlayments—typically cement-based—are poured directly onto the surface to fill low areas and create a flat plane. For wood subfloors, a primer is applied first to help bonding, followed by a fiber-reinforced or latex-modified self-leveling compound designed specifically for flexibility and adhesion to wood. Before leveling, the wood surface must be clean, dry, and securely fastened to avoid shifting or creaking under foot traffic.

Professionals often reinforce wooden subfloors with additional screws or subfloor panels when needed to ensure structural integrity before applying the leveling product. For both wood and concrete, preparation is key to success. According to industry standards, the surface should be level within 1/8 inch over a 10-foot span to meet most flooring manufacturer warranties. With the right technique and product, both types of subfloors can support level, durable, and aesthetically pleasing floors for years to come.
