Installing new flooring is a great way to upgrade your living space. Wood flooring offers timeless style, impressive durability, and can significantly increase your home’s value.
While hiring a professional is often the safest choice, a confident, detail-oriented DIYer can successfully install wood floors with the right tools, materials, and guidance. Use this step-by-step guide to plan, install, and care for new hardwood flooring in your home.
Preparation and Planning
Hardwood floors are extremely popular for their beauty and longevity. They typically cost more than laminate or vinyl, but they’re more durable, repairable, and can be refinished. Before you start, confirm the product you’ve chosen is suitable for your subfloor and room conditions (solid hardwood vs. engineered, nail-down vs. glue-down vs. floating).
Acclimate the flooring: Wood needs to adjust to your home’s temperature and humidity to minimize post-installation movement. Place the sealed boxes in the installation room for at least 48–72 hours (or as the manufacturer recommends), aiming for stable indoor conditions—generally 60–80°F and 30–50% relative humidity. For more on acclimation and moisture, see the National Wood Flooring Association’s homeowner resources: NWFA.
Clear and inspect the space: Remove all furniture, baseboards, and existing flooring. Ensure the subfloor is clean, dry, and flat. Most manufacturers call for flatness within about 3/16 inch over 10 feet (or 1/8 inch over 6 feet). Use a floor scraper, sander, or a self-leveling compound as needed. Address any squeaks by securing loose subfloor panels with screws.
Check moisture: Moisture is the leading cause of wood floor failures. Use an appropriate moisture meter to verify subfloor and flooring moisture levels fall within your product’s specifications and that the difference between them is within industry guidelines (often within 2–4%, depending on board width and product type). On concrete, perform a moisture test and use approved vapor mitigation if required.
If hardwood is the best choice for your space, consider purchasing an installation kit from your local hardware store. Many stores also offer tool rentals for specialty equipment.
Materials and Tools You’ll Need
Gather everything before you begin so you don’t have to stop mid-project:
- Hardwood planks (solid or engineered, per your project)
- Flooring nailer/stapler or hammer with finish nails (per product specs)
- Nails or staples (length and gauge per manufacturer)
- Wood adhesive (for glue-down or some engineered products)
- Underlayment or vapor retarder (per subfloor type and product)
- Moisture barrier (if required, especially over concrete)
- Circular saw and/or miter saw (with fine-tooth blade)
- Jamb saw or oscillating multi-tool (for door casings)
- Tape measure and chalk line
- Spacers, tapping block, pull bar, and pry bar
- Level and straightedge
- Safety gear: eye and hearing protection, dust mask, knee pads
Many of these items can be rented to save money. Check your local tool rental center: The Home Depot Tool Rental.
Step-by-Step Installation Process
1) Plan the layout
Measure the room and sketch a layout. Whenever possible, run planks perpendicular to the floor joists for stability. Start along the longest, straightest, most visible wall and work across the room. Snap a chalk line for your starting edge, factoring in the expansion gap (typically 3/8–1/2 inch, per the manufacturer). Balance your layout so you don’t end up with a very narrow final row.
2) Prepare the subfloor and underlayment
Vacuum thoroughly. For nail-down on wood subfloors, install an approved vapor retarder such as 15-lb asphalt felt or a specialized product. For floating or glue-down engineered floors, use the underlayment or adhesive system specified by the manufacturer. Learn more about underlayment types here: Types of Underlayment.
3) Establish the first row
Begin in a corner with the tongue side facing the room (groove toward the wall), using spacers to maintain your expansion gap. Select straight, long boards for the first row. If the wall isn’t perfectly straight, scribe and trim the boards for a tight, straight starting line.
4) Fasten the planks
For solid hardwood nail-down installations, use a flooring nailer or stapler after the first few rows. The first and last rows may require face-nailing where a nailer won’t fit; fill nail holes with matching wood filler. Typical schedules are fasteners every 8–10 inches and within 2–3 inches of board ends, driven through the tongue at the angle and depth specified by the manufacturer. For engineered floors, follow the recommended method—nail, staple, glue, or float—exactly as specified.
5) Continue with staggered joints
As you proceed, stagger end joints by at least 6 inches for strength and a natural look. Use a miter saw for precise end cuts and a jigsaw or oscillating tool for notches. Keep checking for straightness and maintain the expansion gap around the entire perimeter. Use a tapping block to snug joints together without damaging tongues and grooves.
6) Work around doors and obstacles
Undercut door jambs and casings so the flooring can slide underneath for a clean, professional finish. A jamb saw or oscillating multi-tool works well for this. Dry-fit complex cuts first and use cardboard templates for accuracy. For a walkthrough of key techniques, see this step-by-step from This Old House: How to Install Hardwood Floors.
7) Fit the final row
Rip the last row to width, maintaining your expansion gap. A pull bar and pry bar help draw boards tightly into place without damaging the wall. Face-nail if necessary and fill holes neatly.
8) Finishing touches
Remove spacers. Install baseboards and shoe molding to cover the expansion gap, fastening them to the wall (not the floor). Clean the surface and remove any adhesive residue promptly. Prefinished floors are ready for use; unfinished floors require sanding and finish per manufacturer directions or NWFA guidelines.
Post-Installation Care
Protect your investment with good habits:
- Use felt pads under furniture and avoid stiletto heels or spiked shoes.
- Keep floors clean and dry; sweep or vacuum with a hard-floor setting regularly.
- Maintain stable indoor humidity (typically 30–50%) to minimize seasonal gaps and cupping.
- Refresh finish as needed; solid hardwood can often be sanded and refinished multiple times.

Tips and Tricks for a Professional Finish
Start from the bottom up
A flawless floor requires a solid foundation. Address moisture, flatness, and cleanliness issues in the subfloor to prevent warping, gaps, or squeaks later.
Visualize the laying direction
Dry-lay a few rows at the start and at key transitions to preview plank orientation and pattern. This helps you balance board widths, align with sightlines, and ensure a smooth visual flow between spaces.
Match directions across rooms
When practical, run flooring in the same direction through adjoining rooms or along the home’s longest axis. Consistent direction enhances visual continuity and can make spaces feel larger.
Use the right tools (rent if needed)
Specialty tools like a flooring nailer, tapping block, pull bar, jamb saw, and floor scraper make a big difference in quality and speed. Renting these tools is cost-effective and ensures a cleaner, more precise installation.
Install underlayment correctly
Roll out underlayment or vapor retarders per the product’s instructions. Butt seams (don’t overlap unless specified) and tape them to prevent ridges or noise.
Templates for tricky cuts
Use cardboard templates for areas around pipes, notches, and complex shapes. You’ll save time, reduce waste, and get cleaner results on the first cut.
Work in manageable sections
Divide large rooms into sections so you can continually check straightness, staggering, and fit. Correcting small issues early prevents big problems later.
Clean as you go
Wipe up adhesive and dust promptly to protect the finish and keep joints free of debris. A clean workspace leads to a cleaner installation.
Common Mistakes to Avoid
1) Skipping subfloor prep
An uneven or loose subfloor causes creaks, movement, and premature failure. Verify flatness, secure loose panels, and repair issues before laying the first board.
2) Ignoring moisture checks
Wood expands and contracts with humidity. If installed too wet or too dry relative to the subfloor, boards can later cup, crown, or gap. Test moisture and follow acclimation and vapor mitigation best practices.
3) Rushing the layout
Rooms are rarely perfectly square. Take time to snap reference lines, balance the first and last row widths, and avoid tiny slivers along walls or transitions.
4) Poor racking
“Racking” is how you sequence and stagger boards. Mix board lengths and colors across boxes for a natural, consistent appearance, and maintain proper stagger to prevent weak seams.
5) Too few fasteners
Under-fastening leads to loose boards and squeaks. Follow the manufacturer’s fastener type, spacing, and placement instructions, and ensure tight fits at all edges.
