Step 1: Prepare the Space
Remove Baseboards and Old Flooring
Begin by removing any existing flooring and baseboards to expose the subfloor. This gives you a clean surface and allows for proper edge expansion of the hardwood.
Use a pry bar to carefully lift baseboards, taking care not to damage the drywall so you can reinstall them later. Remove any carpet, vinyl, laminate, or previous hardwood, and ensure all old adhesive or staples are thoroughly scraped off.
Clean and Level the Subfloor
Sweep and vacuum the entire subfloor to remove dust, nails, debris, or glue residue. Then inspect for dips or high points using a straight edge or long level.
For high spots: sand them down.
For low spots: use a floor leveling compound to fill in and smooth out uneven areas.
A flat, even subfloor is crucial for preventing squeaks and ensuring long-term durability.
Check for Moisture or Damage
Moisture is one of the most common causes of hardwood floor failure. Use a moisture meter to test both the subfloor and your hardwood planks.
For wood subfloors: moisture content should typically be below 12%.
For concrete subfloors: follow manufacturer-specific limits — usually below 4% with a calcium chloride test.
If moisture levels are too high, pause installation and address the issue before proceeding.
Install Underlayment or Vapor Barrier (If Required)
Depending on your flooring type and subfloor, you may need an underlayment or moisture barrier:
Over concrete: use a vapor barrier or underlayment with built-in moisture protection.
Over plywood or OSB: a rosin paper, felt underlayment, or foam pad may be recommended.
Follow the manufacturer’s requirements to avoid warranty issues and ensure optimal performance. Lay the underlayment flat, without overlapping, and tape seams where needed.
Step 2: Plan Your Hardwood Layout
Choose Your Starting Wall
For most rooms, it’s best to run hardwood planks parallel to the longest or most visible wall—this creates a sense of flow and makes the space appear larger. If installing in multiple rooms, consider how planks will align through doorways and transitions.
Use a chalk line to snap a straight guideline along your starting wall. This will help you keep your first few rows aligned and ensure the rest of the layout follows a straight path.
Acclimate the Flooring
Before installation, let your hardwood planks acclimate to the room’s temperature and humidity for at least 48 to 72 hours. Lay the boxes flat in the room where the floor will be installed, and open the ends to allow air to circulate.
This helps the wood adjust to the environment and reduces the risk of expansion, warping, or gapping after installation.
Dry-Lay a Few Rows
Lay out a few rows of boards without fastening them to visualize how your layout will look. This allows you to:
Ensure the layout looks balanced across the room
Avoid narrow planks along walls
Plan ahead for obstacles like vents or door frames
Use this opportunity to mix boards from multiple boxes to blend color and grain variation evenly throughout the floor.
Stagger Seams and Avoid Patterns
To create a natural-looking floor, stagger the end joints of planks by at least 6 to 8 inches in adjacent rows. Avoid repeating the same lengths or creating “stair-step” or “H” patterns, which can draw attention to the seams.
Pro tip: Vary your plank lengths and alternate them across rows to create a more organic flow.
Calculate Material (Add Extra for Waste)
Measure the square footage of your space (length × width) and then add 10% to account for cutting waste, mistakes, and future repairs.
If your room has irregular shapes or you’re installing on a diagonal, increase the waste allowance to 12–15%.
Step 3: Choose Your Installation Method
Before you begin laying any boards, you’ll need to decide which installation method is best for your hardwood flooring type and subfloor. Each method has different tools, techniques, and suitability depending on your situation.
Nail-Down Installation (Most Common for Solid Hardwood)
This traditional method is ideal for solid hardwood floors over a wooden subfloor (like plywood or OSB). You’ll use a flooring nailer or stapler to secure each board to the subfloor.
Best for: Solid hardwood over wood subfloors
Tools needed: Flooring nailer, mallet, air compressor
Pros: Very secure and long-lasting
DIY Difficulty: Moderate (requires precision and the right tools)
Glue-Down Installation
Used mainly for engineered hardwood over concrete, this method involves applying flooring adhesive to the subfloor and pressing the boards into place.
Best for: Engineered hardwood over concrete
Tools needed: Flooring adhesive, notched trowel, floor roller
Pros: Strong bond and low profile
DIY Difficulty: Moderate to high (messier and requires ventilation)
Floating Installation (Click-Lock)
This method is popular for DIYers using click-lock engineered hardwood. The planks lock together and “float” over an underlayment without nails or glue.
Best for: Click-lock engineered hardwood over any flat surface
Tools needed: Spacers, tapping block, underlayment
Pros: Fast, clean, beginner-friendly
DIY Difficulty: Easy
Pro Tip: If you’re installing solid hardwood over a wooden subfloor, nail-down is typically the best choice. For engineered hardwood, most DIYers prefer floating floors due to the simpler, tool-free installation process.
Step 4: Mark Guidelines and Snap Chalk Lines
Before you lay your first board, it’s crucial to establish a straight and accurate reference line to guide your installation.
Snap a Chalk Line Along Your Starting Wall
Identify your starting wall—usually the longest or most visible wall in the room. Measure out the width of one board (including the expansion gap) and snap a chalk line parallel to that wall. This will serve as your first row guide.
Use the Line to Keep Rows Straight
As you install the boards, continually align them with the chalk line. This ensures your flooring stays straight across the entire room and doesn’t drift or curve over time.
Leave a 1/2″ Expansion Gap Around the Perimeter
Wood naturally expands and contracts with humidity. Use spacers to leave a 1/2-inch gap between the hardwood and all surrounding walls, door frames, and other fixed obstacles. This allows the floor to expand without buckling.
Step 5: Lay the First Row of Planks
Trim Door Jambs if Needed
Before laying the first plank, check if it needs to slide under any door casings or trim. Use a flush-cut saw or jamb saw to trim the bottoms of door jambs so the planks fit neatly underneath without gaps.
Start with Groove Side Facing the Wall
Place the first plank with the groove side toward the wall — this allows the tongue of the next row to click or lock into place easily. Begin on the longest, straightest wall in the room to ensure the flooring lines up nicely throughout the space.
Secure the First Row
Depending on your installation method:
Nail-down: Use a flooring nailer to fasten the boards into the subfloor through the tongue side.
Glue-down: Spread adhesive with a trowel and press each plank firmly into place.
Floating (click-lock): Angle the second plank into the first and click to lock.
Ensure the planks are tight against one another without gaps along the seams.
Use Spacers to Maintain Expansion Gaps
Insert 1/2″ spacers between the planks and the wall. This gap allows for natural expansion and contraction of the hardwood due to humidity and temperature changes, preventing buckling or warping over time.
Step 6: Install the Remaining Flooring
Once the first row is secured and aligned, continue laying your hardwood planks row by row.
Stagger the End Joints for Stability
For a natural, seamless look and added structural strength, stagger the end joints of each row by at least 6 inches. Avoid aligning joints across consecutive rows, as this weakens the floor and creates a repetitive pattern.
Use a Tapping Block for a Tight Fit
Place a tapping block against the edge of each plank and gently tap it with a mallet to close gaps. This ensures each board is snug against the last 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 remains flat. Adjust as needed before proceeding to prevent long-term issues.
Step 7: Cut Boards to Fit Edges and Corners
As you approach the walls or obstacles in the room, you’ll need to custom-cut the final planks for a perfect fit.
Measure and Mark Carefully
Use a tape measure to determine the exact space remaining, subtracting 1/2″ to allow for an expansion gap. Mark your plank accordingly with a pencil or chalk.
Use the Right Saw for the Job
Miter saw: Best for clean, straight cuts.
Jigsaw: Ideal for curved cuts around vents, door frames, or irregular shapes.
Always cut on a stable surface and wear safety glasses to protect your eyes from dust and debris.
Maintain Expansion Gaps
Leave a consistent 1/2″ gap between the flooring and all vertical surfaces — including walls, pipes, and cabinetry. This allows the hardwood to naturally expand and contract without buckling.
Step 8: Reinstall Baseboards and Transition Strips
Reattach Baseboards and Shoe Molding
Once your hardwood planks are installed and secure, it’s time to give the room a clean, finished look. Reinstall the baseboards along the perimeter of the room. If your original trim included shoe molding, reinstall that too for a polished finish.
Install Transition Strips
At doorways and where hardwood meets another flooring type (like tile or carpet), install the appropriate transition strips. These include T-moldings, reducers, or threshold transitions depending on the height and material of the adjacent flooring.
Leave Room for Movement
When nailing or gluing down trim, make sure not to fasten it directly to the hardwood flooring. Doing so can restrict expansion and contraction and may lead to buckling. All trim should be secured to the wall or subfloor—not the floating floor itself.
Step 9: Clean and Inspect Your Floor
Once installation is complete, take the time to clean and inspect your new hardwood floor to ensure everything is in top shape before use.
Sweep and Vacuum Thoroughly
Remove all sawdust, wood chips, and debris using a broom or vacuum with a soft-brush attachment. This not only gives you a clear view of the floor but also prevents scratches during inspection or furnishing.
Inspect for Issues
Check for visible gaps, uneven planks, or creaking sounds as you walk across the floor. Use a tapping block to snug up any slightly misaligned boards or consult your installation method if adjustments are needed.
Let the Floor Settle
If you used glue-down installation, wait at least 24–48 hours before placing furniture or rugs. This allows the adhesive to fully cure and prevents shifting.
Pro Tips for a Successful Hardwood Installation
Getting professional-looking results with hardwood flooring is all about preparation and precision. These tips will help you work smarter and avoid frustration:
Always test for moisture using a moisture meter before installation — this helps prevent cupping or buckling later.
Use knee pads to protect your joints during long hours of floor work, and ensure proper ventilation if you’re using adhesives.
Check alignment every few rows to make sure planks stay straight and flush.
Work in manageable sections rather than rushing the entire room at once — this helps maintain quality.
Take your time on cuts. Clean, accurate cuts make all the difference in creating tight seams and professional results.
Common Mistakes to Avoid When Installing Hardwood
Even experienced DIYers can run into issues if these common missteps aren’t avoided:
Skipping the acclimation period can cause the wood to expand or contract after installation.
Neglecting subfloor moisture and flatness leads to instability, noise, or gaps.
Failing to stagger seams weakens the structural integrity and creates an uneven appearance.
Nailing too close to the edge of the plank can cause splits or cracks.
Forgetting to use spacers leaves no room for expansion, which can lead to buckling.
