How to Lay Laminate Flooring on Wood: Step-by-Step Guide: Pro Tips, Real User Lessons & Common Mistakes (From a Designer’s Perspective)

Laying laminate flooring over an existing wood surface is one of the smartest, most budget-friendly upgrades you can make—whether you’re remodeling a classic brownstone or refreshing your first apartment. As a senior interior designer, I love recommending laminate for its durability, huge style selection, and (maybe best of all) the fact that most homeowners can DIY the install. Here’s how to do it right—and skip common headaches.

Project Planning: Laying Laminate Over Wood Floors

Before you rip open boxes of planks, assess your current wood floor. The surface should be level, clean, dry, and structurally sound. Laminate flooring is a floating system, meaning it needs a flat base but not perfect wood below. If you spot high spots, uneven boards, or excessive squeaking, address those issues first. It’s usually as easy as securing loose boards with finishing nails or using a leveling compound in small areas.

One client story that sticks with me: Amanda, a DIY enthusiast in Portland, tackled her living room with laminate right over her old pine floors. But she skipped checking for level, and the new floor had a noticeable sway. After redoing the job with a proper prep step, her results were flawless.

Choose the Right Tools & Materials

For a successful install, you’ll need:

1. Underlayment (if not pre-attached to the laminate)
2. Measuring tape and pencil
3. Utility knife
4. Pull bar and tapping block
5. Spacers for wall gaps
6. Handsaw or jigsaw
7. Rubber mallet

If you need help visualizing your floor, consider using a 2D floor planner. It’s a game changer for measuring, laying out planks, and troubleshooting tricky layouts like bay windows or angled walls.

Installing Laminate Flooring: Key Steps

1. Acclimate the Planks: Keep unopened laminate boxes in the room for 48 hours. This helps the planks adjust to the space, preventing gaps after installation.

2. Prepare the Wood Subfloor: Sweep and clean thoroughly. Fix squeaks and level minor dips. Lay underlayment if required by your product—it dramatically improves feel and sound.

3. Plan Your Layout: Lay out rows parallel to the longest wall or the main window for the best look.

4. Start First Row: Place spacers along the starting wall for a 1/4-inch expansion gap. Snap planks together, cutting the last piece to fit. Save leftovers for the next row’s starter piece (minimize waste and keep seams staggered).

5. Continue Rows: Use the tapping block/mallet to lock planks tightly. Stagger seams at least 8 inches between adjacent rows. Keep checking for a crisp, tight fit—gaps or raised corners mean you need to realign.

6. Finishing Touches: Once complete, remove spacers. Install baseboards or quarter-round molding to cover expansion gaps.

Common Mistakes & Simple Fixes

Through countless renovations, I’ve seen (and fixed) all the rookie errors. Here are the big ones to avoid:

1. Skipping underlayment: Even over wood, underlayment helps prevent creaks and supports joints—well worth the small extra cost.
2. Not staggering seams: Straight seams look unnatural and weaken the floor.
3. Forgetting the expansion gap: This is crucial for laminate, especially if you live somewhere with big seasonal humidity swings.
4. Trying to hammer planks into place: Always use a block—direct hammering can crack plank edges.

Level of Detail & Time Commitment

Installing laminate flooring in an average 12x15 foot room usually takes one full day if you prep well. Newbies should set aside a weekend. I always remind clients that slow, careful cuts and double-checking rows save hours (and headaches!) later. If you’re pressed for time or confidence, even partial help—like hiring a handyperson for step one—can make the next steps a breeze.

1. Q: Can I lay laminate flooring directly over old hardwood?
2. A: Yes, as long as the old wood floor is level, stable, and dry. Prep is key—clean and fix any loose boards first.
3. Q: Do I need to remove the baseboards before installing?
4. A: It’s best for a flush, finished look, but not strictly required. If left in place, use quarter-round molding to cover the expansion gap.
5. Q: Is a vapor barrier needed over wood?
6. A: Usually no, unless your subfloor is over a crawlspace or the area is susceptible to moisture. In most dry, above-grade installations, underlayment alone is sufficient.
7. Q: Which direction should I lay my planks?
8. A: Run planks parallel to the longest wall or toward the main window for natural light emphasis. Use a virtual floor planner if unsure.
9. Q: Can I use laminate in kitchens?
10. A: Yes—but choose water-resistant or waterproof laminate for kitchens and always wipe spills promptly to prevent damage.
11. Q: What if there are big gaps between my existing floorboards?
12. A: For gaps over 1/8”, fill with floor-leveling compound. Large structural issues may require subfloor repair.
13. Q: Can I install laminate over engineered wood?
14. A: Absolutely—if the engineered wood is well-fastened and flat, it makes an ideal subfloor.
15. Q: Is it better to glue or float laminate?
16. A: Most modern laminate is designed to float; gluing isn’t required and may void warranties.
17. Q: What’s the best way to cut laminate?
18. A: A handsaw, jigsaw, or laminate shear works well. Always cut face-up to avoid chipping.
19. Q: Can I reuse the existing underlayment?
20. A: It’s usually better to start fresh, unless it’s in pristine condition and compatible with your new laminate.
