How to Replace Hardwood Floors

Published in Hardwood Floor Installation 6 mins read

Replacing hardwood floors is a rewarding home improvement project that revitalizes your living space, combining the meticulous removal of old flooring with the precise installation of new wood. The process, while detailed, can be broken down into manageable steps, ensuring a beautiful and durable result.

1. Preparation and Old Floor Removal

The initial phase of replacing hardwood floors is critical and sets the foundation for a successful installation.

  • Clear the Room: Begin by completely emptying the room of all furniture, appliances, and decorative items.
  • Remove Baseboards and Trim: Carefully pry off existing baseboards, shoe molding, and door casings. Label them to ensure they can be reinstalled in their original locations if you plan to reuse them.
  • Demolish Old Flooring: If you're replacing existing hardwood, use a pry bar, hammer, and circular saw (set to the depth of the flooring) to cut and lift the old boards. For other flooring types like carpet or tile, the removal method will vary. Ensure all staples, nails, or adhesive residues are thoroughly removed.
    • Tip: Always wear appropriate personal protective equipment (PPE) including safety glasses, gloves, and a dust mask during demolition.
  • Prepare the Area (Subfloor Inspection and Repair): Once the old flooring is removed, thoroughly inspect the subfloor. This is a crucial step that directly impacts the longevity and appearance of your new floor.
    • Check for any loose areas and re-secure them with screws.
    • Address any squeaks by screwing the subfloor into the joists below.
    • Level any high spots by sanding or low spots by filling with a self-leveling compound or shims. A flat subfloor prevents unevenness and potential gaps in your new hardwood.
    • Clean the subfloor thoroughly, removing all debris, dust, and nails.
  • Acclimate New Flooring: Allow your new hardwood planks to acclimate to the room's temperature and humidity for at least 3-5 days (or as recommended by the manufacturer) before installation. This prevents expansion or contraction issues after installation. Stack the unopened boxes flat in the room where they will be installed.

2. Planning the Layout

Careful planning ensures an aesthetically pleasing and efficient installation.

  • Determine Board Direction: Generally, hardwood is laid parallel to the longest wall in the room or perpendicular to the floor joists to maximize stability. In hallways, lay boards in the direction of traffic flow.
  • Establish a Starting Line: Measure the width of your room and the width of a single plank, factoring in a 1/2 to 3/4-inch expansion gap along all walls. Use a chalk line to mark your starting point, ensuring the first row is perfectly straight. It's often best to start near an exterior wall or the longest, most visible wall.

3. Hardwood Floor Installation Process

Installing hardwood floors involves precise cuts and secure fastening.

  • Starting the First Row:
    • Begin by laying the first row of boards along your chalk line, tongue side facing into the room.
    • Countersink the Nails: Since you can't use a blind nailer on the first row without hitting the wall, the first few rows typically need to be face-nailed through the surface of the board. Drill pilot holes and then secure the boards with finishing nails. Use a nail punch to countersink the nails below the surface, filling the holes later with wood putty for a clean finish.
    • Ensure the boards are straight and securely fastened.
  • Fit and Lock the Boards:
    • Subsequent rows are installed by aligning the tongue of the new board into the groove of the previously installed board.
    • Use a tapping block and a mallet to gently fit and lock the boards together tightly, ensuring there are no gaps between planks.
    • Vary the end joint placement from row to row (stagger joints) to create a stronger, more visually appealing floor. Aim for at least 6-8 inches of stagger between end joints in adjacent rows.
  • Use a Flooring Stapler (or Nailer): For the majority of the installation, a pneumatic flooring stapler or nailer is used for "blind nailing." This tool drives fasteners through the tongue of the board at an angle, securing it to the subfloor without visible nails on the surface.
    • Blind Nailing: Position the stapler/nailer on the tongue of the board and strike it with a mallet to drive the fastener. This method is quick, efficient, and creates a strong hold.
  • Working Across the Room: Continue laying rows, ensuring the expansion gap is maintained around the perimeter using spacers. Cut boards to fit at the end of each row, using the leftover piece (if long enough) to start the next row.
  • Fitting Around Obstacles: Carefully measure and cut boards to fit around door jambs, vents, and other obstacles using a jigsaw or coping saw.

4. Finishing Hardwood Floor Installation

The final steps involve bringing your new floor to its pristine state and adding the necessary trim.

  • Final Inspection and Cleaning: Once all boards are laid, remove all spacers and thoroughly clean the floor.
  • Finish Hardwood Floor Installation (Sanding and Sealing - for unfinished wood): If you installed unfinished hardwood, this stage involves:
    • Sanding: Rent a drum sander and edge sander to sand the entire floor, typically starting with a coarse grit and progressing to finer grits for a smooth finish.
    • Staining (Optional): Apply a wood stain if desired, following the manufacturer's instructions.
    • Sealing: Apply several coats of a protective finish (polyurethane or water-based sealant) to guard against wear and moisture. Always follow the product's drying times between coats.
  • Finishing (for prefinished wood): If you installed prefinished hardwood, this step is much simpler, usually just requiring a thorough cleaning to remove any dust or debris from installation.
  • Install the Transition Pieces: Install any necessary transition strips between your new hardwood and adjacent flooring types (e.g., tile, carpet) to create a smooth, safe, and aesthetic connection. Secure them according to the manufacturer's instructions.
  • Reinstall Baseboards and Trim: Reinstall the baseboards and shoe molding around the perimeter of the room. This covers the expansion gap and provides a finished look. Nail them into the wall studs, not the floor.

Tips for a Successful Hardwood Floor Replacement

  • Read Instructions: Always follow the specific installation guidelines provided by your hardwood flooring manufacturer.
  • Rent Tools: Many specialized tools like flooring staplers and sanders can be rented from home improvement stores, saving you money.
  • Work Smart: Break the project into smaller tasks. Work in sections to maintain momentum and precision.
  • Patience is Key: Don't rush the process, especially during subfloor preparation and board acclimation. Rushing can lead to costly mistakes.

Replacing hardwood floors is a significant undertaking, but with careful planning, proper tools, and a systematic approach, you can achieve a beautiful and lasting transformation of your home.
