The idea is tempting: keep the hardwood, save demo cost, avoid dust, and still get the new look. Many homeowners in and around Rancho Cordova, Citrus Heights, Folsom, Fair Oaks, and El Dorado Hills ask the same question: can you install laminate over existing hardwood?
At Floor Store of Sacramento, we typically answer: often yes, sometimes no, and the difference is the condition of the hardwood underneath. Laminate is a floating floor. It needs a stable, flat, non-moving platform. If the hardwood is acting like a trampoline or a washboard, the laminate will eventually show it.
When Installing Laminate Over Hardwood Is a Good Idea
You’re usually in the “yes” zone if:
The hardwood is structurally sound (no loose boards, no widespread squeaks you can’t fix).
The surface is flat within tolerance (dips/humps are minimal).
The hardwood is dry (no moisture intrusion from below).
You can handle height changes at doors, appliances, and transitions.
This approach can be ideal when hardwood is cosmetically outdated or too worn to refinish, but still mechanically stable.
When You Should NOT Install Over Hardwood
Avoid it if any of these are true:
Significant cupping or crowning
If boards are cupped (edges higher) or crowned (center higher), the surface isn’t flat. Floating laminate over a wavy surface increases joint stress and can cause seam gaps.Loose boards / nail pops / widespread squeaks
Laminate doesn’t “fix squeaks.” It often amplifies them. Any movement below becomes noise and bounce above.Moisture problems
If the hardwood is over a damp crawl space or there’s known moisture intrusion, covering it can trap moisture and worsen the underlying issue.Height constraints
Adding laminate + underlayment raises the floor. That can cause:Doors scraping or not closing
Dishwasher or stove clearance problems
Awkward step-ups at adjacent rooms
Stair/landing code and safety issues
Technical Checklist: How to Prep Hardwood for Laminate
Step 1: Check flatness like a pro
Use a long straightedge. Mark:
high spots (humps)
low spots (dips)
If the hardwood has localized high edges, you may be able to sand high points. For larger dips, you may need a patching compound approved for wood substrates, but only after the floor is secured and stable.
Step 2: Eliminate movement and squeaks
This is the step most people skip, then regret.
Re-fastening loose boards with screws into joists can reduce squeaks.
Replace damaged boards that flex.
If squeaks come from subfloor-to-joist movement, address from below (crawl space) if possible.
If you can’t stabilize the floor, don’t cover it. You’ll be installing a “nice-looking amplifier” on top of a problem.
Step 3: Clean and decontaminate the surface
Laminate underlayment needs a clean surface. Remove:
grit and debris
wax buildup
staples, protruding nails
thick adhesive residue (from old carpets)
Step 4: Choose the right underlayment
On hardwood, you usually want an underlayment that:
provides sound reduction without excessive softness
avoids bounce that stresses locking joints
matches manufacturer specs for thickness and compression
Do not “double pad” unless the laminate brand explicitly permits it.
Step 5: Plan height and transitions
Before installation, measure:
door clearances
transition needs to tile/carpet
appliance clearances
baseboard/trim strategy
Often, the cleanest finish is: keep baseboards, install laminate with expansion gaps, then add shoe molding (or remove/reinstall baseboards for the most seamless look).
Step 6: Respect floating-floor rules
Don’t run laminate under fixed cabinetry or heavy islands unless the product allows it.
Use transitions where required, especially in doorways and long runs.
Maintain expansion gaps everywhere.
Hot take: “Covering hardwood” isn’t always lazy
Sometimes it’s the smartest path if the hardwood is stable but you want:
better scratch resistance
a different color trend
simpler maintenance
or a waterproof-adjacent lifestyle setup (with the right laminate)
The key is doing the prep like you’re building a system, not just laying planks.
Yes, laminate can be installed over existing hardwood, but only when the hardwood is flat, stable, and dry, and you plan for height, squeaks, and transitions. If the floor underneath moves, the laminate above will eventually complain.
