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 helps make a clean surface for the new flooring.
Use a pry bar to gently remove baseboards without harming the wall, so you can put them back later. Take out any vinyl or laminate, and make sure all glue or staples are gone.
Clean and Make Subfloor Even
Sweep and vacuum the whole subfloor to get rid of dust, nails, or glue. Check for dips or bumps with a straight edge or long level.
- For high spots: sand them.
- For low spots: use a floor leveling compound to fill and smooth.
A flat subfloor is key to stopping squeaks and making the floor last.
Look for Moisture or Damage
Moisture can ruin floors. Use a moisture meter to check both the subfloor and your flooring.
- For wood subfloors: keep moisture content below 12%.
- For concrete subfloors: follow manufacturer limits, usually below 4%.
If moisture is too high, fix it before moving on.
Put Down 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 underlayment with moisture protection.
- Over plywood or OSB: use rosin paper, felt underlayment, or foam pad as needed.
Follow the manufacturer’s guidelines to avoid issues and get the best results. Lay the underlayment flat, without overlaps, and tape seams if needed.
Step 2: Plan Your Hardwood Layout
Choose Your Starting Wall
For most rooms, it’s good to lay planks parallel to the longest or most visible wall. This helps the room look bigger. If doing multiple rooms, think about how planks will line up through doorways.
Use a chalk line to make a straight guideline on your starting wall. This keeps your rows straight and helps the rest of the layout stay on track.
Acclimate the Flooring
Before you start, let the planks get used 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 to flow.
This helps the wood fit the space better and lowers chances of expansion, warping, or gaps after it’s installed.
Dry-Lay a Few Rows
Lay out some boards without attaching them to see how your design will look. This lets you:
- Check if the layout looks balanced in the room
- Avoid narrow planks near walls
- Plan for things like vents or door frames
Mix boards from different boxes to even out color and grain differences across the floor.
Stagger Seams and Avoid Patterns
To make a natural-looking floor, stagger the plank ends by at least 6 to 8 inches in nearby rows. Don’t repeat lengths or create “stair-step” or “H” patterns, which can highlight the seams.
Tip: Change plank lengths and switch them across rows for a more organic look.
Calculate Material (Add Extra for Waste)
Measure your space (length × width) and add 10% for cutting waste, mistakes, and future fixes.
If your room is oddly shaped or you’re laying planks diagonally, increase the waste to 12–15%.
Step 3: Choose Your Installation Method
Before starting, choose the best way to install your flooring based on the type and subfloor you have. Each way needs different tools and skills.
Nail-Down Installation (Most Common for Solid Floors)
This is great for solid floors on wooden subfloors like plywood. Use a nailer to attach each board.
- Best for: Solid flooring over wood subfloors
- Tools needed: Flooring nailer, mallet, air compressor
- Pros: Very secure and long-lasting
- DIY Difficulty: Moderate (needs precision and the right tools)
Glue-Down Installation
Mainly for engineered floors on concrete, this uses adhesive to stick boards to the subfloor.
- Best for: Engineered flooring over 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 using click-lock floors. Planks connect and “float” over underlayment without nails or glue.
- Best for: Click-lock flooring over any flat surface
- Tools needed: Spacers, tapping block, underlayment
- Pros: Fast, clean, beginner-friendly
- DIY Difficulty: Easy
Pro Tip: For solid flooring over wood, nail-down works best. For engineered flooring, many DIYers like floating floors for the easy installation.
Step 4: Mark Guidelines and Snap Chalk Lines
Before you start installing, make sure you have a straight guide line.
Snap a Chalk Line Along Your Starting Wall
Find your starting wall, usually the longest or most visible one. Measure the width of one board (including the gap needed) and snap a chalk line parallel to that wall. This will be your guide for the first row.
Use the Line to Keep Rows Straight
When putting down the boards, always align them with the chalk line. This keeps your flooring straight throughout the room.
Leave a 1/2″ Expansion Gap Around the Perimeter
Wood changes with humidity. Use spacers to leave a 1/2-inch gap between the floor and walls, door frames, and other edges. This lets the floor expand without problems.
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 saw to trim the bottoms of door jambs so the planks fit snugly underneath without spaces.
Start with Groove Side Facing the Wall
Put the first plank with the groove side toward the wall. This way, the tongue of the next row clicks or locks in place easily. Start on the longest, straight wall in the room to make sure the flooring lines up well across 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 in 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 at the seams.
Use Spacers to Maintain Expansion Gaps
Put 1/2″ spacers between the planks and the wall. This gap lets the floor expand and contract naturally with humidity and temperature changes, stopping it from buckling or warping over time.
Step 6: Install the Remaining Flooring
Start with the first row securely in place, then continue laying the planks row by row.
Stagger the End Joints for Stability
To make the floor strong and look natural, stagger the end joints of each row by at least 6 inches. Do not align joints in consecutive rows, as it weakens the floor.
Use a Tapping Block for a Tight Fit
Place a tapping block on the edge of each plank and gently tap with a mallet to close gaps. This makes each board fit snugly without damaging it.
Secure Boards Based on Your Method
- Nail-down: Nail through the tongue at a 45° angle every 6–8 inches.
- Glue-down: Spread glue evenly and press planks firmly.
- Floating floor: Click boards together at the ends and sides.
Check for Level Frequently
Every few rows, use a level to make sure the floor is flat. Adjust if needed to prevent problems later.
Step 7: Cut Boards to Fit Edges and Corners
When you get close to the walls or things in the room, cut the last planks so they fit right.
Measure and Mark Carefully
Use a tape measure to find out how much space is left. Take away 1/2″ for an expansion gap. Mark the plank with a pencil or chalk.
Use the Right Saw for the Job
- Miter saw: Good for straight cuts.
- Jigsaw: Best for curved cuts around things like vents or doors.
Always cut on a steady surface and wear safety glasses to keep your eyes safe from dust.
Maintain Expansion Gaps
Leave a 1/2″ gap between the flooring and all vertical surfaces, like walls and pipes, so the floor can move without problems.
Step 8: Reinstall Baseboards and Transition Strips
Reattach Baseboards and Shoe Molding
After the flooring is in place, 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.
Install Transition Strips
Add transition strips at doorways and where different floors meet, like tile. This includes T-moldings, reducers, or thresholds, depending on the floor height and material.
Leave Room for Movement
When attaching trim, do not fix it to the flooring directly. This can stop the floor from moving and cause issues. Trim should be attached to the wall or subfloor, not the floor itself.
Step 9: Clean and Inspect Your Floor
After installation, clean and check your new floor to make sure everything is perfect before using it.
Sweep and Vacuum Thoroughly
Use a broom or a vacuum with a soft brush to remove sawdust and dirt. This helps you see the floor clearly and avoids scratches when you check it or add furniture.
Inspect for Issues
Look for gaps, uneven parts, or noise when walking on the floor. Use a tapping block to fix any misaligned boards or follow your installation guide for adjustments.
Let the Floor Settle
For glue-down floors, wait 24–48 hours before adding furniture or rugs. This gives the glue time to set properly and keeps the floor stable.
Pro Tips for a Successful Hardwood Installation
Achieving great results with flooring needs careful planning. These tips will help you work better and avoid trouble:
- Always check for moisture with a moisture meter before putting down floors — this stops problems like cupping or buckling.
- Wear knee pads to keep your joints safe during long work hours, and make sure there is good ventilation if using adhesives.
- Ensure proper alignment every few rows so that planks remain straight and even.
- Work in small sections instead of rushing through the whole room — this keeps the quality high.
- Be careful with cuts. Clean, precise cuts are key for tight seams and professional results.
Common Mistakes to Avoid When Installing Flooring
Even experienced DIYers can face problems if they don’t avoid these common mistakes:
- Skipping the acclimation period can make the wood expand or shrink after installation.
- Ignoring subfloor moisture and flatness can cause instability, noise, or gaps.
- Not staggering seams weakens the structure and looks uneven.
- Nailing too close to the edge can make the wood split or crack.
- Not using spacers leaves no room for expansion, which can cause buckling.
