Why Subfloor Leveling Matters

Uneven, cracked, or improperly prepared subfloors can compromise even the most well-planned flooring project. Poor subfloor conditions often lead to visible imperfections, premature wear, adhesive breakdown, and even complete flooring failure. Whether it's a small dip in concrete or widespread undulation across an entire slab, these issues can impact the performance and appearance of the finished floor.

CB Flooring's subfloor leveling services are designed to eliminate those risks. By addressing surface irregularities before installation, we provide a smooth, stable foundation that supports high-performance flooring in demanding commercial environments. This extra step in preparation helps extend the life of flooring systems while supporting a cleaner, more professional finish.

What Is Subfloor Leveling?

Subfloor leveling is the process of correcting imperfections in a concrete or wood substrate to achieve a flat, even surface before flooring is installed.


This process typically involves:

  • 1
    Identifying dips, high spots, and cracks using precision tools and visual inspections
  • 2
    Applying self-leveling underlayment compounds to create a uniform surface
  • 3
    Grinding or scarifying high areas when necessary
  • 4
    Ensuring the subfloor meets industry tolerances for the specified flooring system

At CB Flooring, our trained installation crews use high-quality materials and equipment to manage this process efficiently—even on large job sites or in tight timelines. We evaluate each site condition independently and propose leveling solutions that fit the specific flooring type being installed, whether it’s carpet tile, resilient sheet goods, hardwood, or large-format porcelain.



Industries We Serve

CB Flooring provides subfloor leveling for a wide variety of commercial projects. Whether the installation is happening in a brand-new facility or as part of a renovation, we coordinate with general contractors and project managers to make sure the subfloor is properly addressed before flooring is laid.

Signs That Subfloor Leveling Is Needed

Subfloor imperfections are not always visible at first glance. CB Flooring conducts on-site assessments to identify early warning signs and recommends leveling solutions accordingly.



Some Indicators Include:


  • 1
    Identifying dips, high spots, and cracks using precision tools and visual inspections
  • 2
    Applying self-leveling underlayment compounds to create a uniform surface
  • 3
    Grinding or scarifying high areas when necessary
  • 4
    Ensuring the subfloor meets industry tolerances for the specified flooring system

Addressing these issues early can save considerable time and cost later in the construction process. CB Flooring's comprehensive subfloor leveling solutions help minimize rework, reduce installation errors, and improve overall performance.

Our Leveling Process


CB Flooring follows a systematic process for all subfloor leveling work. Our process integrates tightly with the overall flooring schedule to prevent delays and keep the site ready for installation.

Step 1: Site Evaluation


Before any leveling work begins, we conduct a detailed site walk to assess the condition of the subfloor. We measure for flatness, look for visual defects, and determine whether the surface is within tolerance for the specified flooring system. This step allows us to provide accurate recommendations and cost estimates.

Step 2: Surface Preparation


Based on the evaluation, our crews prepare the surface using grinders or scarifiers as needed. We remove any old adhesives, debris, or contaminants that could interfere with bonding. In some cases, moisture testing is conducted to confirm conditions are acceptable for self-leveling underlayments.

Step 3: Application of Self-Leveling Underlayment


Using high-performance leveling compounds, we apply a self-leveling system across the subfloor. These products are engineered to flow easily and fill in low areas while drying into a smooth, consistent layer. The result is a flat surface that meets industry standards and is ready for installation.

Step 4: Final Inspection and Transition to Installation


Once the underlayment has cured, our team conducts a final inspection and verifies that the subfloor is suitable for flooring installation. At this point, the project transitions to our installation crew, who will begin placing the selected flooring product with confidence in the base below.
