Step 1: Prepare the Space
Take Out Baseboards and Old Flooring
Start by taking out the current flooring and baseboards to see the subfloor. This provides a clean area and helps with proper edge expansion of the new floor.
Use a pry bar to gently remove baseboards, being careful not to harm the drywall so they can be put back later. Take out any carpet, vinyl, or laminate, and make sure all old glue or staples are completely removed.
Clean and Even Out the Subfloor
Sweep and vacuum the whole subfloor to clear dust, nails, trash, or glue leftovers. Then look for dips or high spots using a straight edge or long level.
- For high spots: sand them.
- For low spots: use a floor leveling compound to fill and smooth uneven areas.
A flat, even subfloor is key to stopping squeaks and ensuring the floor lasts long.
Check for Water or Damage
Water can often cause floor problems. Use a moisture meter to check both the subfloor and your wood planks.
- For wood subfloors: moisture should usually be below 12%.
- For concrete subfloors: follow specific limits — often below 4% with a calcium chloride test.
If water levels are too high, stop installing and fix the problem before going on.
Put in Underlayment or Vapor Barrier (If Needed)
Based on your floor type 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 could be suggested.
Follow what the manufacturer says to avoid warranty issues and get the best results. Lay the underlayment flat, without overlapping, and tape seams if needed.
Step 2: Plan Your Hardwood Layout
Pick Your Starting Wall
It’s usually best to lay hardwood planks parallel to the longest or main wall in a room. This helps the room feel bigger. If you’re working in several rooms, think about how planks will line up through doorways.
Snap a chalk line for a straight guide along your starting wall. This keeps your first rows straight and helps the rest of the layout stay on track.
Let the Flooring Acclimate
Before you start, let your hardwood planks sit in the room for 48 to 72 hours to get used to the temperature and humidity. Lay the boxes flat and open the ends for air.
This helps the wood get used to the room and stops it from changing shape after you install it.
Try a Dry-Lay
Put down a few rows of boards without nailing them to see how they will look. This helps you:
- Make sure the layout looks nice
- Avoid thin planks by walls
- Plan for things like vents or doorways
Mix boards from different boxes to spread color and grain evenly.
Stagger Seams and Mix Patterns
Make your floor look natural by staggering the ends of planks by 6 to 8 inches in the next rows. Stay away from repeating lengths or creating patterns like “stair-step” or “H.”
Tip: Use different plank lengths across rows for a more natural look.
Estimate Material (Include Extra for Waste)
Find your space’s square footage (length × width) and add 10% for waste, mistakes, and repairs.
If the room is oddly shaped or you’re laying planks diagonally, increase waste allowance to 12–15%.
Step 3: Choose Your Installation Method
Before starting, choose the best way to install your hardwood based on the type and subfloor. Each method uses different tools and techniques.
Nail-Down Installation (Common for Solid Hardwood)
This method works well for solid hardwood on wooden subfloors. 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
This is mainly for engineered hardwood on concrete. Apply adhesive and press boards in place.
- Best for: Engineered hardwood on concrete
- Tools needed: Flooring adhesive, notched trowel, floor roller
- Pros: Strong bond and low profile
- DIY Difficulty: Moderate to high (messy and needs ventilation)
Floating Installation (Click-Lock)
Great 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 often best. For engineered hardwood, floating floors are easier for DIYers.
Step 4: Mark Guidelines and Snap Chalk Lines
Before you start putting down boards, make sure to make a straight line to help with installation.
Draw a Chalk Line Along Your Starting Wall
Find your starting wall, usually the longest or most noticeable in the room. Measure the width of one board, including the space for expansion, and draw a chalk line parallel to that wall. This line will guide your first row.
Use the Line to Keep Rows Straight
When you place the boards, keep them in line with the chalk line. This will help the flooring stay straight and not curve over time.
Leave a 1/2″ Expansion Gap Around the Edges
Wood changes with humidity. Use spacers to leave a 1/2-inch gap between the flooring and walls, door frames, and other obstacles. This gap lets the floor expand without bending.
Step 5: Lay the First Row of Planks
Trim Door Jambs if Needed
Before putting down the first plank, see if it needs to go under any door frames or trim. Use a flush-cut saw or jamb saw to cut the bottoms of door jambs so the planks fit nicely without gaps.
Start with Groove Side Facing the Wall
Put the first plank with the groove side toward the wall. This helps the next row’s tongue click or lock easily. Begin on the longest, straight wall in the room to keep the flooring lined up well.
Secure the First Row
Depending on how you’re installing:
- Nail-down: Use a nailer to secure the boards into the subfloor through the tongue side.
- Glue-down: Spread adhesive with a trowel and press each plank firmly.
- Floating (click-lock): Angle the second plank into the first and click to lock.
Make sure the planks are snug against each other without gaps along the seams.
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 problems 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.
