Step 1: Prepare the Space
Take Out Baseboards and Old Flooring
Start by taking away any old flooring and baseboards to see the subfloor. This gives a clean area and helps hardwood edges fit right.
Use a pry bar to gently lift baseboards without damaging the wall so you can put them back later. Remove any carpet, vinyl, laminate, or hardwood, and make sure all old glue or staples are well scraped off.
Clean and Level the Subfloor
Sweep and vacuum the subfloor to clear dust, nails, debris, or glue. Check for dips or high spots using a straight edge or long level.
- For high spots: sand them down.
- For low spots: use a floor leveling compound to fill and smooth uneven areas.
A flat subfloor is important to stop squeaks and make floors last longer.
Check for Moisture or Damage
Moisture can ruin hardwood floors. Use a moisture meter to test the subfloor and hardwood planks.
- For wood subfloors: moisture should be below 12%.
- For concrete subfloors: follow maker limits — usually below 4% with a calcium chloride test.
If moisture is too high, stop installing and fix the issue first.
Install Underlayment or Vapor Barrier (If Needed)
Depending on your flooring and subfloor, you might need an underlayment or moisture barrier:
- Over concrete: use a vapor barrier or underlayment with moisture protection.
- Over plywood or OSB: a rosin paper, felt underlayment, or foam pad might be recommended.
Follow maker rules to avoid warranty issues and get the best performance. Lay the underlayment flat, without overlapping, and tape seams where needed.
Step 2: Plan Your Hardwood Layout
Choose Your Starting Wall
In most rooms, lay hardwood planks parallel to the longest or most visible wall to make the room look bigger. For multiple rooms, think about how planks will line up through doorways.
Snap a chalk line for a straight guideline on your starting wall. This keeps your first rows straight so the rest of the floor stays aligned.
Acclimate the Flooring
Before starting, let hardwood planks sit in the room for 48 to 72 hours to get used to the temperature and humidity. Lay boxes flat and open the ends for air to move around.
This helps prevent the wood from expanding, warping, or leaving gaps later.
Dry-Lay a Few Rows
Lay a few rows of boards without attaching them to see how they will look. This helps you:
- Keep the layout balanced across the room
- Avoid narrow planks near walls
- Plan for things like vents or door frames
Mix boards from different boxes to spread color and grain evenly across the floor.
Stagger Seams and Avoid Patterns
Stagger the end joints of planks by 6 to 8 inches in nearby rows for a natural look. Avoid repeating lengths or making patterns like “stair-step” or “H,” which highlight seams.
Tip: Use different plank lengths and switch them across rows for a natural flow.
Calculate Material (Add Extra for Waste)
Figure out the square footage of your room (length × width) and add 10% extra for cutting waste and repairs.
If your room is oddly shaped or you’re laying planks diagonally, increase the waste to 12–15%.
Step 3: Choose Your Installation Method
Before you start putting down boards, choose the best way to install your hardwood based on type and subfloor. Each way needs different tools and techniques.
Nail-Down Installation (Common for Solid Hardwood)
This method is great for solid hardwood on a wooden subfloor. 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 precision and right tools)
Glue-Down Installation
Mainly for engineered hardwood on concrete, this involves gluing boards to the subfloor.
- 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 ventilation)
Floating Installation (Click-Lock)
Popular for DIYers, this uses click-lock engineered hardwood. Planks lock together and float over an underlayment.
- Best for: Click-lock engineered hardwood on any flat surface
- Tools needed: Spacers, tapping block, underlayment
- Pros: Fast, clean, beginner-friendly
- DIY Difficulty: Easy
Pro Tip: For solid hardwood on wood subfloors, nail-down is best. For engineered hardwood, many prefer floating floors because it’s easier and doesn’t need tools.
Step 4: Mark Guidelines and Snap Chalk Lines
Before you start laying boards, make a straight line to guide your work.
Draw a Chalk Line Next to the Starting Wall
Locate the starting wall, often the longest or most visible one. Measure the width of a board (adding a gap for expansion) and draw a chalk line parallel to the wall. This guides your first row.
Align Rows with the Line
As you lay the boards, align them with the chalk line. This ensures your flooring stays straight and doesn’t bend or move over time.
Leave a 1/2″ Expansion Gap at the Edges
Wood reacts to humidity. Use spacers to maintain a 1/2-inch gap between the floor and walls, door frames, and other fixed objects. This allows the floor to expand without problems.
Step 5: Lay the First Row of Planks
Trim Door Jambs if Needed
Check if the first plank needs to slide under door frames or trim. Use a saw to cut the bottom of door jambs so the planks fit neatly without gaps.
Start with Groove Side Facing the Wall
Place the first plank with the groove side next to the wall. This helps the next row fit easily. Start on the longest, straight wall in the room to keep the flooring even.
Secure the First Row
Depending on how you install:
- Nail-down: Use a flooring nailer to attach the boards to the floor through the tongue side.
- Glue-down: Spread glue with a trowel and press each plank firmly.
- Floating (click-lock): Angle and click the second plank into the first.
Ensure the planks fit tightly together without gaps.
Use Spacers to Maintain Expansion Gaps
Place 1/2″ spacers between the planks and the wall. This gap allows the wood to expand and contract naturally, preventing buckling or warping.
Step 6: Install the Remaining Flooring
Once the first row is down and straight, keep adding hardwood planks one row at a time.
Stagger the End Joints for Stability
Make the floor strong and smooth by staggering end joints of each row by at least 6 inches. Avoid lining up joints in rows, as this can weaken the floor and create a pattern.
Use a Tapping Block for a Tight Fit
Place a tapping block against the plank edge and tap it gently with a mallet to close gaps. This ensures each board fits tightly without damaging the tongue or groove.
Secure Boards Based on Your Method
- Nail-down: Drive nails through the tongue at a 45° angle every 6–8 inches.
- Glue-down: Spread adhesive evenly and press planks firmly 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 stays flat. Adjust if needed before proceeding to avoid future issues.
Step 7: Cut Boards to Fit Edges and Corners
When you get near walls or other things, you must cut the last planks to fit.
Measure and Mark Carefully
Use a tape measure to find the exact space left, taking off 1/2″ for an expansion gap. Mark the 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.
Always cut on a steady surface and wear safety glasses to protect your eyes from dust and debris.
Maintain Expansion Gaps
Keep a 1/2″ gap between the floor and all vertical surfaces like walls, pipes, and cabinets. This helps the hardwood expand and contract naturally without bending.
Step 8: Reinstall Baseboards and Transition Strips
Reattach Baseboards and Shoe Molding
After installing your hardwood planks, tidy up the room by reattaching the baseboards around the edges. If there was shoe molding before, put it back for a nice finish.
Install Transition Strips
Where hardwood meets other floors, like carpet, use the right transition strips. Choose T-moldings, reducers, or threshold transitions depending on the height and material of the other floor.
Leave Room for Movement
When adding trim, avoid nailing or gluing it to the hardwood floor. This can prevent the floor from moving and lead to buckling. Attach all trim to the wall or subfloor, not the floating floor.
Step 9: Clean and Inspect Your Floor
After installation, clean and check your new hardwood floor to ensure it’s ready for use.
Sweep and Vacuum Thoroughly
Use a broom or vacuum with a soft brush attachment to remove sawdust, wood chips, and debris. This allows you to see the floor clearly and avoids scratches during inspection or finishing.
Inspect for Issues
Check for gaps, uneven boards, or creaks when walking. Use a tapping block to adjust any slightly misaligned boards or refer to your installation guide for adjustments.
Let the Floor Settle
If glue was used, wait 24–48 hours before placing furniture or rugs. This gives the glue time to set completely, preventing movement.
Pro Tips for a Successful Hardwood Installation
Achieving great results with hardwood floors requires good preparation and care. Here are some tips to help you:
- Always check moisture with a meter before you start — this stops cupping or buckling later on.
- Wear knee pads to protect your joints and make sure there’s good ventilation if using glue.
- Keep checking alignment so planks stay straight and even.
- Work in small areas instead of doing the whole room at once — this keeps quality high.
- Be careful with cuts. Clean cuts help create tight seams and look professional.
Common Mistakes to Avoid When Installing Hardwood
Even skilled DIYers can face problems if they make these mistakes:
- Skipping the acclimation time may cause the wood to change size after laying it down.
- Ignoring subfloor moisture and flatness can make floors unstable, noisy, or leave gaps.
- Not staggering seams weakens the floor and looks uneven.
- Nailing too close to the edge can cause planks to split or crack.
- Forgetting spacers means no room for expansion, leading to buckling.
