We get called out for laminate repairs all over Durham, and after 16 years of it, the cause is almost always one of the same five things. Most of the time it isn’t the homeowner’s fault. It’s a DIY job that missed a step, or a crew that rushed the part nobody sees. The good news is that all five are avoidable, and most are fixable once you know what you’re looking at.
Here are the five we fix most often, what causes them, and how to keep them off your floor.
1. No expansion gap, which is most of the buckling we see
This is the number one repair we do. A laminate floor floats, meaning it isn’t glued or nailed down, and it has to have a little room around the edges of the room to expand when our summers get humid. Leave that gap out and the boards have nowhere to go, so they push against each other and lift in the middle of the room. That’s the peaking and buckling people call us about every June and July.
We pulled up a floor in a Woodcroft townhouse last summer that had been installed tight against every wall. By the time the humidity peaked, the whole hallway had tented up an inch. The planks themselves were fine. The install just never left them room to move. The fix is to pull the baseboard, trim the laminate back to restore the gap, and reset it, and the floor lays flat again.
2. Laying laminate over a damp subfloor or open crawl space
A lot of Durham homes sit over crawl spaces, especially the older ones in neighborhoods like Trinity Park and Forest Hills. If that crawl space is damp and the subfloor was never sealed against ground moisture, that damp works its way up into the back of the planks for months. Laminate’s fiberboard core swells once it takes on water, and unlike hardwood you can’t sand it back. The floor is just done.
This is why we check subfloor moisture before a single plank goes down, and why we’ll tell a homeowner to deal with a wet crawl space first. The EPA’s guide to mold and moisture in the home is a good plain-English read on why keeping that moisture in check matters for the whole house, not just the floor. If we see standing water or a musty crawl space on the estimate, we say so. Putting a new floor over a known moisture problem is the kind of shortcut that comes back in a year.
3. Skipping acclimation
Laminate needs to sit in your house for a couple of days before it goes down, in the rooms where it’s being installed. That lets the planks settle to your home’s temperature and humidity first. Skip it, and the floor finishes adjusting after it’s already locked together, which is how you end up with gaps opening between boards in the dry winter or edges lifting in the humid summer.
It’s the easiest step to rush because it costs time, not money, and a crew trying to finish in a day will skip it. We don’t. The planks acclimate first, every time, because it’s free insurance against a callback.
4. Cheap or wrong underlayment
The thin pad that rolls out under the planks does more than quiet the floor. On a concrete slab or a crawl-space subfloor it’s also the moisture barrier between the ground and the back of your boards. We see two versions of this mistake: no underlayment at all, which leaves the floor sounding hollow and unprotected, and the wrong type for the subfloor, like a foam pad with no vapor barrier laid straight over concrete.
Getting this right is part of why our floors don’t fail early. If you want to see how the whole thing fits together, our laminate flooring installation page walks through the prep, the underlayment, and the steps that keep a floor flat for 20 years. The pad is cheap. Redoing a floor because the pad was wrong is not.
5. Putting laminate in the wrong room, then wet-mopping it
Laminate is water-resistant, not waterproof, and the two most common ways we see it killed by water are putting it somewhere it shouldn’t be and cleaning it the wrong way.
Bathrooms, laundry rooms, and below-grade basements are not the place for laminate, no matter how good the plank is. For those rooms we steer people toward luxury vinyl plank, which is fully waterproof. The other half of this one is care: a steam mop or a sopping-wet mop drives water down into the seams, where it swells the core from the top instead of the bottom. A damp microfiber mop is all laminate ever needs. Steam mops have ended more laminate floors in Durham than almost anything except a hidden leak.
Already seeing one of these on your floor?
If your laminate is peaking, gapping, sounding hollow, or lifting at the seams, it’s usually one of the five above, and catching it early often means we can fix a section instead of replacing the room. We handle laminate repairs and installs across the whole Triangle from our Durham base, including Durham, Raleigh, Cary, Chapel Hill, Carrboro, and Wake Forest.
