Step 1: Prepare the Space
Take Away Baseboards and Old Flooring
Start by taking out the old flooring and baseboards to show the subfloor. This makes a clean area and helps with the proper fit of the hardwood.
Use a pry bar to gently lift the baseboards, being careful not to harm the drywall so you can put them back later. Remove any carpet, vinyl, laminate, or old hardwood, and make sure all old glue or staples are scraped off well.
Clean and Make the Subfloor Even
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 places: sand them down.
- For low places: use a floor leveling mix to fill and smooth uneven areas.
A flat, even subfloor is important to stop squeaks and make sure it lasts a long time.
Look for Moisture or Damage
Moisture often causes hardwood floor problems. Use a moisture meter to check both the subfloor and your hardwood pieces.
- For wood subfloors: moisture should usually be under 12%.
- For concrete subfloors: follow specific limits from the maker — often under 4% with a calcium chloride test.
If moisture is too high, stop installation and fix the issue before moving on.
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: rosin paper, felt underlayment, or foam pad might be suggested.
Follow the maker’s instructions to avoid warranty problems and ensure it works well. Lay the underlayment flat, without overlaps, and tape seams where needed.
Step 2: Plan Your Hardwood Layout
Pick Your First Wall
In most rooms, it’s best to lay hardwood planks parallel to the longest or most noticeable wall. This helps the room look bigger. If you’re installing in more than one room, think about how the planks will line up through doorways.
Use a chalk line to mark a straight guide along your first wall. This keeps the first rows straight and ensures the rest follow the path.
Let the Flooring Adjust
Before you start, let the hardwood planks adjust to the room’s temperature and humidity for 48 to 72 hours. Place the boxes flat in the room and open the ends for air circulation.
This helps the wood settle into the environment, reducing the chances of expansion or gaps later on.
Test-Lay Some Rows
Lay out a few rows of boards without attaching them to see how they’ll look. This helps you:
- Make sure the layout is balanced
- Avoid skinny planks near walls
- Plan for obstacles like vents
Mix boards from different boxes to even out color and grain variations.
Stagger Joints and Avoid Patterns
For a natural look, stagger plank ends by 6 to 8 inches in each row. Avoid patterns like “stair-step” or “H” that highlight the seams.
Tip: Vary plank lengths and mix them across rows for a more natural look.
Figure Out Materials (Include Extra for Waste)
Measure your space (length × width) and add 10% for cutting waste and errors.
If your room is oddly shaped or you’re laying planks diagonally, increase the waste allowance to 12–15%.
Step 3: Choose Your Installation Method
Before you start putting down boards, pick the right way to install your hardwood flooring based on the type and the subfloor. Each way needs different tools and methods.
Nail-Down Installation (Most Common for Solid Hardwood)
This old-fashioned way works great for solid hardwood on a wooden subfloor like plywood. Use a flooring nailer or stapler to fix each board to the subfloor.
- Best for: Solid hardwood over wood subfloors
- Tools needed: Flooring nailer, mallet, air compressor
- Pros: Very strong and lasts long
- DIY Difficulty: Medium (needs accuracy and the right tools)
Glue-Down Installation
Mostly used for engineered hardwood on concrete, this way requires spreading flooring glue on the subfloor and pressing boards down.
- Best for: Engineered hardwood over concrete
- Tools needed: Flooring adhesive, notched trowel, floor roller
- Pros: Strong hold and low profile
- DIY Difficulty: Medium to hard (messy and needs air)
Floating Installation (Click-Lock)
This is popular for DIYers with click-lock engineered hardwood. Planks snap together and “float” over underlayment without nails or glue.
- Best for: Click-lock engineered hardwood over any flat surface
- Tools needed: Spacers, tapping block, underlayment
- Pros: Fast, clean, good for beginners
- DIY Difficulty: Easy
Pro Tip: If laying solid hardwood on a wooden subfloor, nail-down is usually best. For engineered hardwood, many DIYers choose floating floors because they’re simpler to install.
Step 4: Mark Guidelines and Snap Chalk Lines
Before you lay your first board, set a straight line to help with the installation.
Draw a Chalk Line on Your Starting Wall
Find your starting wall, usually the longest one. Measure the width of one board (including the gap) and draw a chalk line parallel to that wall. This line will guide your first row.
Keep Rows Straight with the Line
When placing the boards, align them with the chalk line. This will keep your floor straight and prevent it from shifting or bending over time.
Leave a 1/2″ Gap for Expansion
Wood changes with humidity. Use spacers to leave a 1/2-inch gap between the floor and nearby walls, door frames, and other obstacles. This allows the floor to expand without problems.
Step 5: Lay the First Row of Planks
Trim Door Jambs if Needed
Before you start, see if the first plank needs to go under any door frames or trim. Use a saw to cut the bottoms so the planks fit neatly without gaps.
Start with Groove Side Facing the Wall
Place the first plank with the groove side against the wall. This helps the next row’s tongue click into place easily. Start on the longest, straightest wall so the floor lines up well.
Secure the First Row
Depending on how you install:
- Nail-down: Use a nailer to attach the boards to the floor through the tongue side.
- Glue-down: Spread glue with a tool and press each plank down firmly.
- Floating (click-lock): Angle the second plank into the first and click to lock.
Make sure the planks are tight with no gaps at the seams.
Use Spacers to Maintain Expansion Gaps
Put 1/2″ spacers between the planks and the wall. This gap is for natural expansion and contraction due to changes in humidity and temperature, 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.
