To ensure the durability of your hardwood floor and prevent squeaks or unevenness in the finished product, proper preparation of the subfloor is crucial. This process involves multiple steps, such as inspecting and cleaning the subfloor thoroughly to ensure its structural integrity.
You must also assess moisture levels and flatness before proceeding with removing an existing flooring or making repairs to any damaged areas. Installing a plywood layer can help even out low spots on the surface. Additionally, underlayment is crucial when installing laminate or vinyl flooring.
By being mindful of these details and following the manufacturer’s instructions carefully, homeowners can achieve a successful installation that will last for years. Below we give you all guidelines on how to prepare a subfloor for wood flooring:
1. Remove Current Flooring, Doors, Baseboards, Trim
Prior to installing hardwood flooring, it is crucial to remove all current flooring, doors, baseboards, and trim from the subfloor. This will provide a seamless and level surface for new wood planks to adhere correctly. Before beginning this process, though, homeowners must inspect the subfloor carefully for any imperfections, such as low spots or cupping.
If found, they should be handled by using levelling compound or sanding them down. Following this step-by-step guide, along with the manufacturer’s instructions, will lead to a successful installation.
2. Make Sure It’s Flat And Even
Before you start with how to prepare a subfloor for the wood flooring installation process, you must ensure that the surface is perfectly levelled and smooth. A flat subfloor ensures easy installation of hardwood flooring without any squeaks.
Using a self-levelling compound helps to achieve accuracy while reducing cupping and other imperfections. Additionally, homeowners should make sure their floors are moisture-free before installing wooden planks. Installing hardwood flooring requires proper care; follow the manufacturer’s instructions for best results.
3. Inspect & Clean The Subfloor
Before installing hardwood flooring on your subfloor, you must ensure a level and clean surface. Check for any imperfections or unevenness. Thoroughly clean the area by removing debris or adhesive residue from the subfloor. Sand down any high spots or use the self-levelling compound to create an even surface.
Moisture levels in the subfloor must be checked before installation as it can affect durability. An appropriate underlayment should be used to reduce noise and provide a moisture barrier as per the manufacturer’s instructions.
4. Ensuring Structural Integrity
A successful installation of hardwood flooring starts with ensuring that your subfloor is structurally sound. Checking for damage like cracks or rotting and replacing any affected areas before installing new flooring is essential. It’s also important to verify that the subfloor is level and flat to avoid movement or squeaking in your newly installed hardwood floor.
Another crucial step is testing your subfloor’s moisture content to prevent cupping or warping of the wood in humid conditions. Finally, always follow the manufacturer’s instructions for proper care.
5. Assessing The Subfloor For Moisture
To make sure that your hardwood flooring remains durable for years to come, it is essential to assess the subfloor for moisture. Moisture can negatively impact wood floors by causing them to warp, buckle or develop mould and mildew.
Therefore, properly assessing and addressing moisture issues must top your priority list before installing any wood flooring. There are different methods to evaluate the level of moisture content in your subfloor, such as using a moisture meter or conducting a calcium chloride test.
6. Checking For Flatness
Before installing hardwood flooring, it’s essential to check the subfloor for flatness. Using a long level or screed, ensure that there are no high or low spots on the subfloor. If there are any high spots, use a floor sander to remove them, while low spots can be filled with a levelling compound. A flat and even subfloor will reduce the risk of squeaks and movement in your beautiful hardwood floors.
7. Removing The Current Flooring
Begin by using tools such as a pry bar, hammer, and utility knife to remove any remnants of the old flooring. Ensure that all adhesive residue is cleaned off and the subfloor is swept clean before proceeding. If necessary, sand or repair the subfloor if it’s uneven or damaged before installing new hardwood flooring.
8. Repairing Any Damaged Subfloor
Inspect your subfloor for damages like cracks and holes before installing hardwood flooring. Remove any loose or damaged floorboards and replace them with new ones. Fill in any imperfections using wood filler and sand it down until smooth. For an uneven subfloor, use a self-levelling compound to attain a flat surface. Allow repairs to dry completely before installation of your preferred hardwood plank.
9. Installing A Plywood Layer
To ensure a successful installation of your new hardwood floor, take time to properly prepare the subfloor. Installing a plywood layer perpendicular to the floor joists will provide the stability and support needed for long-term durability.

Achieving a seamless finish for your wood floor involves cutting baseboards and mounding accurately. Measure them precisely before using a miter saw or coping saw to make precise cuts. Ensure there are no rough edges by sanding before installing. This will result in an attractive hardwood floor that homeowners can be proud of.
Tips For Ensuring A Level Subfloor
Before installing hardwood flooring, homeowners need to ensure that their subfloor is level and free from imperfections. This involves addressing high or low spots with levelling compound or plywood while also performing a moisture test to determine if a moisture barrier is necessary.
