Step 1: Prepare the Space
Take Away Baseboards and Old Flooring
Start by taking out any old flooring and baseboards to reveal the subfloor. This gives a clear surface for the hardwood to expand properly at the edges.
Use a pry bar carefully to lift baseboards without harming the drywall, so they can be reused. Remove any carpet, vinyl, laminate, or old hardwood, and make sure to scrape off all old glue or staples.
Clean and Level the Subfloor
Sweep and vacuum the whole subfloor to clear dust, nails, debris, or glue bits. Then check for dips or high spots using a straight edge or long level.
- If there are high spots: sand them down.
- If there are low spots: fill and smooth them with a floor leveling compound.
A flat, even subfloor stops squeaks and helps the floor last longer.
Check for Moisture or Damage
Moisture often causes hardwood floors to fail. Use a moisture meter to check both the subfloor and 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 the installation 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: rosin paper, felt underlayment, or foam pad might be suggested.
Follow the manufacturer’s rules to avoid warranty issues and ensure the best performance. Lay the underlayment flat, without overlapping, and tape seams if needed.
Step 2: Plan Your Hardwood Layout
Pick Your Starting Wall
In most rooms, run hardwood planks parallel to the longest or most visible wall to make the room feel bigger. If doing multiple rooms, think about how planks line up through doorways.
Use a chalk line to draw a straight guideline along the starting wall. This helps keep the first rows straight.
Let the Flooring Adjust
Before putting down the hardwood, let the planks adjust to the room’s temperature and humidity for at least 48 to 72 hours. Lay the boxes flat in the room and open the ends for air.
This helps the wood fit the space better and prevents changes after installation.
Try a Dry Layout
Put down a few rows of boards without attaching them to see how they look. This helps you:
- Make sure the layout is even
- Avoid narrow planks by walls
- Plan for things like vents or door frames
Mix boards from different boxes to spread color and grain evenly.
Stagger Seams
For a natural look, stagger plank ends by at least 6 to 8 inches in adjacent rows. Avoid making patterns like “stair-step” or “H”.
Tip: Use different plank lengths and switch them across rows for a more natural flow.
Figure Out Material Needs
Measure your space (length × width) and add 10% for waste and future repairs.
If the room is oddly shaped or the planks are diagonal, increase waste allowance to 12–15%.
Step 3: Choose Your Installation Method
Before starting, choose the best way to install your hardwood floors based on the type and subfloor. Each way uses different tools and methods, depending on your needs.
Nail-Down Installation (Common for Solid Hardwood)
This classic way works well for solid hardwood on wooden subfloors like plywood. Use a flooring nailer or stapler to attach the boards.
- Best for: Solid hardwood on wood subfloors
- Tools needed: Flooring nailer, mallet, air compressor
- Pros: Very secure and lasts long
- DIY Difficulty: Moderate (needs accuracy and proper tools)
Glue-Down Installation
Great for engineered hardwood on concrete, this method uses adhesive on the subfloor to stick the boards down.
- Best for: Engineered hardwood on concrete
- Tools needed: Flooring adhesive, notched trowel, floor roller
- Pros: Strong hold and low height
- DIY Difficulty: Moderate to high (messy and needs ventilation)
Floating Installation (Click-Lock)
DIYers like this method for click-lock engineered hardwood. The planks snap together and “float” over an underlayment without using 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 a wooden subfloor, nail-down is often best. For engineered hardwood, many choose floating floors because they are simpler and don’t need tools.
Step 4: Mark Guidelines and Snap Chalk Lines
Before you start laying boards, make sure to create a straight line. This will help you install the floor correctly.
Make a Chalk Line Along the First Wall
Find the first wall to start with, usually the longest or most noticeable in the room. Measure the width of one board, including a gap for expansion, and draw a chalk line parallel to the wall. This will guide your first row.
Keep Boards Aligned with the Line
While putting down the boards, always check they line up with the chalk line. This keeps the floor straight and prevents it from bending over time.
Leave a 1/2″ Gap for Expansion
Wood changes size with humidity. Use spacers to keep a 1/2-inch gap between the wood and nearby walls or fixed objects. This helps the floor expand without issues.
Step 5: Lay the First Row of Planks
Trim Door Jambs if Needed
Before you start, check if the plank needs to go under door frames or trim. Trim the bottom of the door jambs with a flush-cut saw so the planks fit nicely without gaps.
Start with Groove Side Facing the Wall
Set the first plank with the groove side toward the wall. This makes it easy for the next row to click in place. Start on the longest, straightest wall to keep the flooring aligned.
Secure the First Row
Depending on how you install:
- Nail-down: Use a nailer to attach the boards through the tongue side to the subfloor.
- Glue-down: Spread glue with a trowel and press each plank in place.
- Floating (click-lock): Angle the second plank into the first and click to lock it.
Make sure the planks are tight together without gaps.
Use Spacers to Maintain Expansion Gaps
Place 1/2″ spacers between the planks and the wall. This lets the wood expand and contract due to humidity and temperature changes, preventing buckling or warping.
Step 6: Install the Remaining Flooring
After you secure the first row, keep placing your hardwood planks one row at a time.
Stagger the End Joints for Stability
To make the floor stronger and look smooth, stagger the end joints by at least 6 inches. Don’t line up joints in a row, as this weakens the floor.
Use a Tapping Block for a Tight Fit
Put a tapping block at the plank’s edge and tap it gently with a mallet to close gaps. This makes sure each board fits tightly without damage.
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.
- Floating floor: Click boards together end-to-end and side-to-side.
Check for Level Frequently
Use a level every few rows to keep the floor flat. Adjust if needed to avoid future problems.
Step 7: Cut Boards to Fit Edges and Corners
When you get close to walls or things in the room, you’ll need to cut the last planks to fit perfectly.
Measure and Mark Carefully
Use a tape measure to find the exact space left, subtract 1/2″ for an expansion gap. Mark your plank with a pencil or chalk.
Use the Right Saw for the Job
- Miter saw: Best for clean, straight cuts.
- Jigsaw: Good for cutting curves around vents, door frames, or odd shapes.
Always cut on a stable surface and wear safety glasses to keep your eyes safe from dust and debris.
Maintain Expansion Gaps
Leave a 1/2″ gap between the flooring and all vertical surfaces like walls, pipes, and cabinets. This lets the hardwood expand and contract naturally without bending.
Step 8: Reinstall Baseboards and Transition Strips
Put Back Baseboards and Shoe Molding
After the hardwood planks are set and firm, make the room look neat by putting back the baseboards around the edges. If there was shoe molding before, put it back too for a nice finish.
Add Transition Strips
In doorways and where hardwood meets other floors (like tile or carpet), add the right transition strips. These may be T-moldings, reducers, or thresholds, depending on the height and material of the other floor.
Allow for Movement
When nailing or gluing trim, don’t attach it straight to the hardwood. This can stop the floor from moving and cause buckling. Trim should be attached to the wall or subfloor, not the floating floor.
Step 9: Clean and Inspect Your Floor
After installing, clean and check your new hardwood floor to make sure it’s ready to use.
Sweep and Vacuum Thoroughly
Use a broom or a vacuum with a soft brush to get rid of all sawdust, wood chips, and dirt. This helps you see the floor clearly and stops scratches when you check or add furniture.
Inspect for Issues
Look for gaps, uneven boards, or creaks when you walk. Use a tapping block to fix any boards that are out of place, or check your installation guide if you need to make changes.
Let the Floor Settle
If you used glue-down installation, wait 24–48 hours before putting furniture or rugs. This gives the glue time to set properly and keeps things from moving.
Pro Tips for a Successful Hardwood Installation
Getting a professional look with hardwood floors needs good preparation and careful work. These tips can help you:
- Always check for moisture with a moisture meter before installation to prevent problems like cupping later.
- Wear knee pads to keep your joints safe, and make sure there’s good ventilation if you use adhesives.
- Check alignment every few rows to keep planks straight and even.
- Work in small sections instead of rushing, which helps keep quality high.
- Take your time with cuts. Neat, exact cuts are key for tight seams and a professional finish.
Common Mistakes to Avoid When Installing Hardwood
Even experienced DIYers can run into trouble if these common mistakes aren’t avoided:
- Skipping the acclimation period can make the wood expand or shrink after it’s installed.
- Ignoring subfloor moisture and flatness can cause instability, noise, or gaps.
- Not staggering seams weakens the floor and looks uneven.
- Nailing too close to the edge of the plank can cause splits or cracks.
- Forgetting to use spacers leaves no room for expansion, causing buckling.
