Everything You’ll Need

<td

Step 1: Prepare the Space

Remove Baseboards and Old Flooring

Start by taking out old flooring and baseboards to see the subfloor. This makes a clean area for the hardwood.

Use a pry bar to gently take off baseboards without hurting the wall, so they can go back later. Remove any old flooring and clean off all glue or staples.

Clean and Level the Subfloor

Sweep and vacuum the subfloor to clear dust, nails, or glue. Check for uneven spots using a straight edge or level.

For high spots: sand them down.
For low spots: fill with a floor leveling compound.

A flat subfloor stops squeaks and makes the floor last longer.

Check for Moisture or Damage

Moisture often causes hardwood problems. Use a moisture meter to check the subfloor and wood planks.

For wood subfloors: keep moisture below 12%.
For concrete subfloors: follow maker’s limits — often below 4% with a test.

If moisture is too high, fix it before continuing.

Install Underlayment or Vapor Barrier (If Required)

You might need underlayment or a moisture barrier based on flooring and subfloor type:

Over concrete: use a vapor barrier or underlayment with moisture protection.
Over plywood or OSB: rosin paper, felt underlayment, or foam pad may be best.

Follow maker’s instructions to keep the warranty and ensure best results. Lay underlayment flat, with no overlaps, and tape seams if needed.

Step 2: Plan Your Hardwood Layout

Choose Your First Wall

It’s usually best to lay hardwood planks along the longest or most noticeable wall to make the room look bigger. If laying planks in more than one room, think about how they’ll join through doorways.

Draw a straight line along your starting wall with a chalk line to keep your first rows straight, so the rest stay aligned.

Prepare the Flooring

Before installation, let the hardwood planks adjust to the room’s temperature and humidity for 48 to 72 hours. Lay the boxes flat in the room and open the ends to allow air to circulate.

This helps the wood adapt to the environment, reducing the risk of size or shape changes later.

Test a Few Rows

Lay down a few rows of boards without fixing them to see how it will look. This lets you:

Ensure the layout is even
Avoid thin planks at the edges
Plan for vents or frames

Use this time to mix boards from different boxes to spread color and grain evenly.

Stagger Joints and Avoid Patterns

For a natural look, stagger plank ends by 6 to 8 inches in nearby rows. Avoid repeating lengths or forming “stair-step” or “H” shapes that can emphasize seams.

Tip: Change plank lengths and swap them in rows for a more natural flow.

Calculate Material (Add Extra for Waste)

Measure your space’s square footage (length × width) and add 10% for cutting waste, mistakes, and future repairs.

If your room has an unusual shape or you lay planks diagonally, increase waste to 12-15%.

Step 3: Choose Your Installation Method

Before you begin, pick the best way to put down your hardwood based on type and subfloor. Each method needs different tools and steps, depending on your setup.

Nail-Down Installation (Common for Solid Hardwood)

This way is good for solid hardwood on wood subfloors like plywood. Use a nailer or stapler to attach each board.

Best for: Solid hardwood on wood subfloors
Tools needed: Flooring nailer, mallet, air compressor
Pros: Very secure and lasts long
DIY Difficulty: Moderate (needs accuracy and right tools)

Glue-Down Installation

Perfect for engineered hardwood on concrete. Use glue on the subfloor and press boards down.

Best for: Engineered hardwood on concrete
Tools needed: Flooring adhesive, notched trowel, floor roller
Pros: Strong bond, low profile
DIY Difficulty: Moderate to high (messy, needs good air)

Floating Installation (Click-Lock)

DIYers like this for click-lock engineered hardwood. Planks lock and “float” over underlayment without nails or glue.

Best for: Click-lock engineered hardwood on any flat surface
Tools needed: Spacers, tapping block, underlayment
Pros: Fast, clean, easy for beginners
DIY Difficulty: Easy

Pro Tip: For solid hardwood on wood subfloors, nail-down is best. For engineered, floating floors are popular with DIYers for easy, tool-free setup.

Step 4: Mark Guidelines and Snap Chalk Lines

Before you begin, draw a straight line for your flooring.

Draw a Line by Your First Wall
Locate your first wall, usually the longest. Measure a board’s width, including room for expansion, and draw a line next to the wall. This line guides your first row.

Use the Line to Keep Rows Straight
As you place boards, follow the line to keep them straight. This avoids curving over time.

Keep a 1/2″ Gap at the Edges
Wood changes with humidity. Use spacers to maintain a 1/2-inch gap between the floor and walls or obstacles. This prevents buckling.

Step 5: Lay the First Row of Planks

Trim Door Jambs if Needed
If planks need to fit under door trims, trim the door jambs using a saw for a good fit.

Start with Groove Side Facing the Wall
Put the first plank’s groove side next to the wall. This makes locking the next row easier. Begin along the longest wall for a straight look.

Secure the First Row
According to your method:

Nail-down: Attach the boards to the subfloor with a flooring nailer through the tongue side.
Glue-down: Apply glue with a trowel and press each plank into place.
Floating (click-lock): Angle the second plank into the first and click to lock.

Ensure planks are tight with no gaps at the seams.

Use Spacers to Maintain Expansion Gaps
Place 1/2″ spacers between planks and the wall. This gap allows for natural expansion and contraction, preventing buckling over time.

Step 6: Install the Remaining Flooring

Begin with the first row, placing hardwood planks one row at a time.

Stagger the End Joints for Stability
Make the floor look nice and strong by staggering the end joints at least 6 inches apart. Avoid lining them up in a row to keep the floor sturdy.

Use a Tapping Block for a Tight Fit
Place a tapping block on the plank edge and tap gently with a mallet to close gaps. This ensures the boards fit well without damaging the tongue or groove.

Secure Boards Based on Your Method

Nail-down: Nail through the tongue at a 45° angle every 6–8 inches.
Glue-down: Spread glue evenly and press planks into place.
Floating floor: Click boards together end-to-end and side-to-side.

Check for Level Frequently
Every few rows, use a level to ensure the floor is flat. Adjust if needed to prevent issues later.

Step 7: Cut Boards to Fit Edges and Corners

When you reach the room’s edges or other items, cut the last planks to fit right.

Measure and Mark Carefully
Use a tape measure to see the exact space left, and subtract 1/2″ for an expansion gap. Mark your plank with a pencil or chalk.

Use the Right Saw for the Job

Miter saw: Best for straight, clean cuts.
Jigsaw: Good for cutting curves around vents, door frames, or odd shapes.

Cut on a stable surface and wear safety glasses to protect your eyes from dust.

Maintain Expansion Gaps
Leave a 1/2″ gap between the floor and all walls, pipes, and cabinets. This lets the hardwood expand and contract without bending.

Step 8: Reinstall Baseboards and Transition Strips

Reattach Baseboards and Shoe Molding
After you put down hardwood planks, make the room tidy by putting baseboards back around the edges. If there was shoe molding before, add it again for a nice finish.

Install Transition Strips
Where hardwood meets another floor type, like luxury vinyl or laminate, add transition strips. Use T-moldings, reducers, or thresholds based on the height and material of the other floor.

Leave Room for Movement
When attaching trim, do not fix it directly to the hardwood. This lets the floor expand and contract without problems. Secure the trim to the wall or subfloor, not the floating floor.

Step 9: Clean and Inspect Your Floor

After putting in your new hardwood floor, clean it and check to make sure it’s ready to use.

Sweep and Vacuum Well
Use a broom or a vacuum with a soft brush to clear all the sawdust and dirt. This helps you see the floor better and prevents scratches.

Look for Problems
Check for gaps, uneven boards, or noises. Use a tapping block to fix any boards not lined up right, or follow your guide for changes.

Allow the Floor to Settle
If glued down, wait 24–48 hours before putting furniture or rugs on it so the glue can set.

Pro Tips for a Successful Hardwood Installation

For nice hardwood floors, you need to prepare well and be precise. These tips can help you do better work and stay relaxed:

Always check moisture with a meter before starting to prevent issues later.
Use knee pads to protect your joints during long tasks, and make sure there’s good ventilation when using glue.
Check alignment every few rows to keep the planks straight.
Work in small sections instead of doing the whole room quickly to ensure quality.
Be careful with cuts. Clean cuts make tight seams, leading to professional results.

Common Mistakes to Avoid When Installing Hardwood

Even skilled DIYers can run into problems if they don’t avoid these mistakes:

Skipping the acclimation period can make the wood change size after laying it down.
Ignoring subfloor moisture and flatness can cause issues like noise or gaps.
Not staggering seams weakens the floor and makes it look uneven.
Nailing too close to the edge can cause cracks.
Not using spacers leaves no room for the wood to expand, causing buckling.
