Overview

Laminate flooring installation involves laying interlocking, floating planks over a prepared subfloor and underlayment, without nails or glue holding the planks to the floor itself. It's a popular first-time flooring project because the click-together boards are DIY-friendly, forgiving of small measurement errors, and don't require special trade skills — making it realistic for a homeowner who is comfortable with basic tools and willing to spend a weekend on the project.

Tools & materials

  • Laminate flooring planks (add 10% extra for cuts and waste)
  • Foam or film underlayment (with vapor barrier if installing over concrete)
  • Tape measure, pencil, and straightedge or chalk line
  • Circular saw, jigsaw, or laminate flooring cutter for straight and notch cuts
  • Tapping block and rubber mallet or hammer
  • Pull bar for the last row
  • 1/4 to 3/8-inch spacers for expansion gaps
  • Utility knife
  • Moisture meter (especially over concrete subfloors)
  • Transition strips, shoe molding, or quarter-round trim
  • Safety glasses and dust mask

Steps

  1. Let the laminate boxes acclimate in the room where they'll be installed for at least 48 hours so the planks adjust to the home's temperature and humidity.
  2. Remove baseboards, shoe molding, and any old flooring, then check that the subfloor is clean, dry, flat, and free of debris (no more than about 1/8-inch variation over 8 feet).
  3. Test moisture on concrete subfloors with a moisture meter and address any issues before proceeding.
  4. Undercut door jambs and casings with a handsaw so planks can slide underneath for a clean look.
  5. Roll out the underlayment (with a vapor barrier over concrete), butting seams and taping them per the manufacturer's instructions.
  6. Snap a chalk line or measure to plan your starting row along the longest, straightest wall, and dry-fit the first row to check the layout.
  7. Place 1/4 to 3/8-inch spacers against the wall and lay the first row, connecting the short ends of the planks at a slight angle until they click.
  8. Continue row by row, staggering the end joints of adjacent rows by at least 6-8 inches for a natural look and structural stability.
  9. Use a tapping block and mallet to close gaps between planks without damaging the locking edges, and a pull bar to snug up the final row.
  10. Cut planks to fit around doorways, vents, and corners using a jigsaw or laminate cutter, keeping the expansion gap consistent on all sides.
  11. Once the floor is fully laid, remove the spacers, reinstall or add new baseboards and transition strips, and fill any expansion gaps at transitions with matching caulk.

Safety warnings

  • Wear safety glasses when cutting or tapping planks, since chips can fly off the laminate surface.
  • Wear a dust mask or respirator when cutting laminate with a saw, and work in a ventilated area.
  • Use knee pads if you'll be kneeling for extended periods during installation.
  • Handle utility knives and saw blades carefully, cutting away from your body and keeping blades sharp to reduce slipping.
  • Wear work gloves when removing old flooring or handling planks with sharp edges.
  • Keep the work area well-lit and free of tripping hazards like loose tools, cords, or plank offcuts.
  • If you're removing old vinyl tile, sheet flooring, or a black mastic adhesive layer before laying laminate and the home predates the 1980s, treat it as a possible asbestos source - don't sand, dry-scrape, or saw through it; a certified lab test kit (or a pro) can confirm before you disturb it.

When to call a pro

  • The subfloor has soft spots, visible rot, or sags more than 1/8 inch over an 8-foot span even after basic leveling attempts.
  • You find water staining, a musty smell, or suspected mold underneath the old flooring.
  • The existing subfloor needs structural repair or replacement of damaged plywood/OSB sections.
  • You're installing over a large open floor plan with complex transitions, stairs, or multiple rooms of differing heights.
  • Moisture meter readings on a concrete subfloor exceed the laminate manufacturer's maximum allowed level.
  • The layout involves many intricate cuts around cabinetry, built-ins, or curved thresholds beyond your comfort level with a saw.
  • The old flooring, backing, or adhesive you're removing tests positive (or is suspected) for asbestos - stop and call a certified abatement professional rather than continuing removal yourself.

Cost estimate

Roughly $500-$1,500 for a typical room (materials plus tools/underlayment), or about $1.50-$5 per sq ft in materials alone if you already own basic tools
