Each one has its unique set of benefits and considerations, allowing homeowners to choose the solution that best suits their needs and complements their interior design.

What is Uneven Floor?

An uneven floor is a surface that has inconsistencies in its levelness, resulting in a wavy or bumpy appearance and feel. Uneven floors can be caused by various factors, such as settling over time, inadequate subflooring, or even moisture issues that lead to warping or buckling. They can occur in both residential and commercial settings and can present challenges when it comes to choosing and installing the appropriate flooring.

One common issue with uneven floors is that they can lead to poor adhesion of flooring materials, resulting in a less secure and stable surface. Additionally, uneven floors may cause discomfort for those walking on them or lead to potential safety hazards, such as tripping or slipping.

When it comes to addressing an uneven floor, professionals can employ various methods to level the surface before installing new flooring. These techniques may include self-leveling compounds, floor grinding, or using shims or sleepers to create an even plane. However, selecting the best flooring for uneven floors is crucial to ensuring a long-lasting and functional solution.

Different flooring options possess unique qualities that make them more or less suitable for uneven surfaces. In general, some popular choices for uneven floors include vinyl plank flooring, engineered wood, carpet, and laminate. These options tend to balance flexibility and stability, making them a good fit for irregular surfaces.

In conclusion, understanding what uneven floors are and their potential causes can help in the selection of appropriate flooring materials. While some options may be more suitable than others, consulting with a flooring professional can ensure the best possible solution for each specific situation.

Types of Flooring for Uneven Floors


Vinyl is a popular choice for uneven floors due to its flexibility and ease of installation. It is available in various styles, including sheet, plank, and tile, which can accommodate various degrees of unevenness. Vinyl can mimic the appearance of other flooring materials like wood and stone. It provides good durability, water resistance, and low maintenance requirements, making it suitable for various rooms.


Laminate flooring is another option for uneven floors because it can be installed as a floating floor without adhesion to the subfloor, allowing for minor imperfections in the surface. The planks lock together through a tongue-and-groove system, which makes installation simple and quick. It offers a wide variety of designs to resemble natural materials such as wood or stone. Keep in mind that laminate is less water-resistant than vinyl, and may not be suitable for rooms with high moisture levels.

Engineered Wood

Engineered wood is a viable option for uneven floors. It consists of a thin layer of hardwood bonded on top of a plywood base, providing additional stability and resistance to warping. It can be installed as a floating floor, nailed down, or glued to the substrate. Engineered wood provides the appearance and feel of authentic solid hardwood while being more tolerant of uneven surfaces and more affordable.

Ceramic Tiles

Ceramic tiles can be used to cover uneven floors when installed correctly. It is crucial to level the floor as much as possible and use a suitable substrate material, such as cement board, as a base. This will help prevent tiles from cracking or becoming loose. Ceramic tiles offer a durable and water-resistant surface, making them suitable for rooms with high moisture content, such as bathrooms and kitchens.


Linoleum is a resilient flooring material made from natural components like linseed oil, cork, and limestone. It can be laid on an uneven floor as long as the subfloor is reasonably leveled. Its flexible nature allows it to adapt to minor irregularities, while providing a cushioned and comfortable surface to walk on. Linoleum is an eco-friendly option and is available in various designs and colors to suit different tastes.


Carpet is a suitable option for uneven surfaces, as it can conceal slight imperfections and create a cozy and inviting atmosphere. Thick carpet padding can help level the floor and provide additional insulation. However, carpets may not be an ideal choice for rooms with high levels of moisture or a high risk of spills, as they are more difficult to clean and maintain compared to other flooring options.

Assessing Uneven Floors

Identify Causes of Unevenness

The first step in determining the best flooring for uneven floors is to identify the causes of the unevenness. Common factors contributing to an uneven floor include:

  • Subfloor issues: Subfloors made from wood or concrete can warp, crack, or sag over time, leading to an uneven surface.
  • Moisture: Excessive moisture from leaks or humidity can cause wood and concrete to expand, buckle, or rot, creating an uneven floor.
  • Improper installation: Incorrect installation of floor joists, beams, or subflooring can result in an uneven floor.
  • Settling foundation: Over time, the soil beneath a building’s foundation can shift, causing the structure to settle unevenly and leading to an uneven floor.

Evaluate Severity

Once the cause(s) of the unevenness has been identified, it’s essential to evaluate the severity of the floor’s unevenness. Proper evaluation can aid in selecting the most appropriate flooring option. Here are some methods to assess the severity:

  1. Visual inspection: Check for visible gaps, cracks, slopes, or dips in the floor. This can give a basic idea of the floor’s condition.
  2. Level and measuring: Use a long level or a laser level to reveal any discrepancy in the floor’s flatness. Measure the difference in height to quantify the level of unevenness.
  3. Consult a professional: For serious cases of uneven floors or uncertainty in evaluation, consider consulting a professional such as a structural engineer or a flooring installer.

Based on the findings from these assessments, it’s possible to make an informed decision on the type of flooring suitable for uneven floors. Careful consideration of the causes and severity of the unevenness will ensure a durable and aesthetically pleasing flooring solution.

Floor Leveling Techniques

Floor leveling is an important step in dealing with uneven floors. It is primarily done using two methods: self-leveling compounds and plywood subfloors. These techniques ensure a smooth and stable surface for various types of flooring.

Using Self-Leveling Compound

Self-leveling compounds are a type of liquid floor underlayment that is designed to automatically level uneven surfaces when poured. They are easy to use and can generally be applied by homeowners, as well as professionals. Here’s a brief overview of the process:

  1. Preparation: Clean the floor thoroughly, remove any debris, and ensure it is dry. Repair any cracks or holes in the concrete with a patching compound.
  2. Priming: Apply a primer to the floor, which will help the self-leveling compound bond well to the surface.
  3. Mixing the compound: Follow the manufacturer’s instructions to mix the compound with water in a large bucket.
  4. Pouring the compound: Pour the mixture onto the floor, starting in the corner farthest from the door, and work your way out of the room. Use a trowel to spread the compound evenly across the floor.
  5. Curing the compound: Allow the compound to dry for the time specified by the manufacturer, usually 24 hours.

Applying Plywood Subfloor

An alternative method to level uneven floors is to place a plywood subfloor over the existing surface. This is especially useful when dealing with wooden floor structures. Here are the essential steps:

  1. Inspect the floor: Identify high and low spots using a straightedge, such as a level or a straight 2×4. Mark the problem areas.
  2. Cut plywood sheets: Cut plywood sheets to fit the room dimensions and layout, leaving a 1/8-inch expansion gap between the sheets and at the walls. Plywood should be at least a 1/4-inch thick.
  3. Install shims or leveling strips: Place shims or leveling strips on the low spots of the floor to create an even surface.
  4. Secure the plywood: Lay the plywood sheets on top of the shims or leveling strips, staggering the seams and aligning the edges. Nail or screw the plywood to the floor joists below, spacing them approximately every 6 inches along the edges and every 8 inches in the field.
  5. Fill gaps and seams: Use wood filler or floor leveling compound to fill any gaps or seams between the plywood sheets. Sand it smooth once it has dried.

After using one of these techniques, the newly leveled floor should provide a stable and smooth surface for laying flooring materials.
