How to Install Laminate Flooring: DIY Step-by-Step Guide

Laminate flooring is one of the most beginner-friendly flooring projects. A 200 sq ft room can be completed in a weekend, and the tools required are minimal. This guide covers everything from subfloor prep to final trim installation.

What You'll Need

Tools

• Circular saw or miter saw — for straight cross-cuts (see circular saw picks)
• Jigsaw — for cutting around door frames and obstacles (see jigsaw picks)
• Tapping block (often included with flooring)
• Pull bar (for tight rows near walls)
• Rubber mallet
• Tape measure and chalk line
• 1/4-inch spacers (many packs)
• Pencil
• Utility knife

Materials

• Laminate flooring (order 10% extra)
• Underlayment (if not pre-attached to planks)
• Transition strips (for doorways)
• Quarter-round or baseboard trim
• Construction adhesive (for stair nosing if applicable)

Step 1: Acclimate the Flooring

This step is non-negotiable. Laminate must acclimate to the room's temperature and humidity before installation. Skip this and the floor will expand or contract after installation, causing gaps or buckling.

1. Open all boxes and stack planks flat in the room
2. Leave for 48–72 hours minimum
3. Room temperature: 60–80°F; humidity: 35–65%

Step 2: Prepare the Subfloor

The subfloor must be:

• Clean: Remove all debris, old adhesive, and nails/staples
• Flat: Use a long level — maximum 3/16-inch deviation over 10 feet. Fill low spots with floor leveling compound; sand down high spots.
• Dry: Moisture is laminate's enemy. Use a moisture meter — wood subfloor should be under 12% moisture.

Concrete subfloor: Perform a moisture test. Tape plastic sheeting to the concrete for 24 hours — condensation on the underside means too much moisture. Seal with a moisture barrier before installing underlayment.

Step 3: Install Underlayment

Underlayment cushions the floor, reduces noise, and provides a moisture barrier.

1. Roll out underlayment perpendicular to the direction you'll install planks
2. Butt edges together — do NOT overlap (creates a hump in the floor)
3. Tape seams with the foil tape included with the underlayment
4. Cut with a utility knife

Note: If your laminate has pre-attached underlayment (most modern laminate does), skip this step — don't double-layer.

Step 4: Plan the Layout

Key decisions:

• Direction: Run planks parallel to the longest wall and toward the main light source for best visual effect
• Starting wall: Choose the most visible, straightest wall
• Check for square: Measure 3 feet along one wall, 4 feet along the adjacent wall — the diagonal should be exactly 5 feet. Adjust if not.

Calculate first and last row widths: Divide the room width by the plank width. If the last row would be under 2 inches, rip the first row wider to leave a minimum 2-inch last row.

Step 5: Install the First Row

1. Place spacers (1/4 inch) against the starting wall — this is the expansion gap
2. Install the first plank with the tongue side facing the wall
3. Lock the long edge first — engage the long-side click joint of each subsequent plank in the row
4. For the end of the row: measure, mark, and cut the final plank with the circular saw
5. Use the cutoff piece to start the next row — must be at least 12 inches long

Tip: Stagger end joints by at least 12 inches between rows for structural integrity and aesthetics.

Step 6: Install Subsequent Rows

Click-lock installation (most common):

1. Angle the new row's long edge into the previous row's groove at ~30°
2. Lower down — the click-lock should engage with a firm "click"
3. Slide the plank into position and tap the short end joint closed with the tapping block and rubber mallet
4. Work row by row; check alignment every 3–4 rows

For obstacles (pipes, door frames):

• Use the jigsaw for notches around pipes
• For door frames: undercut the door casing with an oscillating tool or hand saw so planks slide underneath
• For irregular cuts: make a template from cardboard first

Step 7: Install the Last Row

The last row almost always requires ripping (cutting lengthwise):

1. Measure the distance from the last installed row to the wall (subtract 1/4 inch for expansion gap)
2. Rip planks to width using the circular saw with a straight-edge guide
3. Use the pull bar to engage the final row joints — the rubber mallet won't fit at the wall
4. Use the pull bar with the rubber mallet to lock planks fully

Step 8: Install Transitions and Trim

Transition strips cover the gap between laminate and adjacent flooring (carpet, tile, etc.) or between rooms.

Quarter-round or baseboard: Covers the 1/4-inch expansion gap around the perimeter.

• Nail into the baseboard or wall — never nail into the floor
• The floor must float freely

Door casings: Apply a bead of caulk where the flooring meets the door threshold if a transition strip isn't used.

Common Mistakes to Avoid

• Skipping acclimation — causes gapping or buckling
• Not leaving expansion gaps — floor buckles in summer humidity
• Nailing the floor to the subfloor — destroys the floating installation
• Hammering directly on planks — always use a tapping block
• Uneven subfloor — causes clicking noise when walking
