Step 1: Prepare the Space
Take Out Baseboards and Old Flooring
Start by taking out the old flooring and baseboards to see the subfloor. This gives you a clean area and helps with hardwood edge expansion.
Use a pry bar to gently lift baseboards, being careful not to harm the drywall so they can be put back later. Remove any carpet, vinyl, laminate, or old hardwood, and make sure to scrape off all old adhesive or staples.
Clean and Level the Subfloor
Sweep and vacuum the whole subfloor to get rid of dust, nails, debris, or glue bits. Then check for low 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, even subfloor is key to stopping squeaks and making the floor last long.
Look for Moisture or Damage
Moisture often causes hardwood floor problems. Use a moisture meter to check both the subfloor and your hardwood planks.
- For wood subfloors: moisture should be below 12%.
- For concrete subfloors: follow specific limits — usually below 4% with a calcium chloride test.
If moisture is too high, stop installation and fix the issue before going on.
Install Underlayment or Vapor Barrier (If Needed)
Depending on your flooring type and subfloor, you might need an underlayment or moisture barrier:
- Over concrete: use a vapor barrier or an underlayment with moisture protection.
- Over plywood or OSB: a rosin paper, felt underlayment, or foam pad might be recommended.
Follow the manufacturer’s instructions to avoid warranty issues and ensure the best performance. Lay the underlayment flat, without overlapping, and tape seams where needed.
Step 2: Plan Your Hardwood Layout
Pick Your First Wall
In most rooms, it’s good to lay hardwood planks parallel to the longest or most noticeable wall—this helps the room feel bigger. When installing in several rooms, think about how planks will line up through doorways and transitions.
Use a chalk line to mark a straight line along your starting wall. This helps keep your first rows straight and the rest of the layout in line.
Let the Flooring Adjust
Before you start, give your hardwood planks time to get used to the room’s temperature and humidity for at least 48 to 72 hours. Lay the boxes flat where you’ll install the floor, and open the ends for air flow.
This allows the wood to get used to the environment and minimizes the chance of expansion, warping, or gaps later on.
Lay Out a Few Rows
Place some rows of boards without attaching them to see how the layout will appear. This helps you:
- Ensure the layout looks even across the room
- Avoid narrow planks by walls
- Plan for obstacles like vents or door frames
Use this time to mix boards from different boxes for even color and grain mix throughout the floor.
Stagger Seams and Avoid Patterns
For a natural look, stagger the ends of planks by at least 6 to 8 inches in nearby rows. Avoid repeating lengths or making “stair-step” or “H” patterns, which can highlight the seams.
Tip: Change up your plank lengths and switch them across rows for a more natural flow.
Estimate Material (Add Extra for Waste)
Measure your space (length × width) and then add 10% for cutting waste, errors, and future fixes.
If your room has odd shapes or you’re installing diagonally, raise the waste allowance to 12–15%.
Step 3: Choose Your Installation Method
Before starting, choose the best way to install your hardwood floor based on its type and the subfloor. Each way uses different tools and is suited for different situations.
Nail-Down Installation (Most Common for Solid Hardwood)
This classic method works well for solid hardwood on a wooden subfloor 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 precision and right tools)
Glue-Down Installation
Mostly for engineered hardwood on concrete, this way uses adhesive on the subfloor to hold the boards.
- Best for: Engineered hardwood on concrete
- Tools needed: Flooring adhesive, notched trowel, floor roller
- Pros: Strong hold and low profile
- DIY Difficulty: Moderate to high (messy and needs ventilation)
Floating Installation (Click-Lock)
Great for DIY, this method uses click-lock engineered hardwood. The planks connect and “float” on underlayment without nails or glue.
- Best for: Click-lock engineered hardwood on any flat surface
- Tools needed: Spacers, tapping block, underlayment
- Pros: Quick, clean, easy for beginners
- DIY Difficulty: Easy
Pro Tip: For solid hardwood on wood subfloors, nail-down is usually best. For engineered hardwood, floating floors are favored by DIYers for their easy, tool-free setup.
Step 4: Mark Guidelines and Snap Chalk Lines
Before you start, draw a straight line to help with your flooring.
Snap a Chalk Line Along Your Starting Wall
Find the starting wall, usually the longest one. Measure the width of one board, including space for expansion, and draw a chalk line parallel to it. This line will guide your first row.
Use the Line to Keep Rows Straight
As you lay the boards, keep them aligned with the chalk line. This keeps the flooring straight and prevents it from curving over time.
Leave a 1/2″ Expansion Gap Around the Perimeter
Wood changes with humidity. Use spacers to leave a 1/2-inch gap between the hardwood and walls, door frames, and other fixed objects. This lets the floor expand without causing problems.
Step 5: Lay the First Row of Planks
Trim Door Jambs if Needed
Before you put down the first plank, check if it needs to go under any door frames or trim. Use a flush-cut saw or jamb saw to trim the bottoms of door frames 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 way, the tongue of the next row can lock into place easily. Start on the longest, straightest wall in the room to make sure the flooring lines up nicely throughout the space.
Secure the First Row
Depending on how you install:
- Nail-down: Use a flooring nailer to attach the boards to the subfloor through the tongue side.
- Glue-down: Spread glue with a trowel and press each plank firmly into place.
- Floating (click-lock): Angle the second plank into the first and click to lock.
Make sure the planks are tight against each other without gaps along the seams.
Use Spacers to Maintain Expansion Gaps
Put 1/2″ spacers between the planks and the wall. This gap lets the hardwood expand and contract naturally 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.
