Is it necessary to level the subfloor before installing LVP flooring?

Do you think it’s necessary to level the subfloor before installing LVP?
Yeah, that’s pretty much it. If the subfloor is uneven, the tile will crack or not sit properly
If the floor is super uneven, there’s a risk of the lip breaking or separating when the planks flex. It can also create a hollow sound because of the floating installation.
Absolutely, if you don’t follow the instructions, your laminate could end up cracking, separating, or both.
Actually, most vinyl flooring will adjust to the floor underneath. If there are significant dips, you might need some filler, but generally, it’s meant to float on top.
Yeah, definitely stick to the manufacturer’s guidelines for floor tolerance. It’s super important. If you don’t, the joints will likely break or separate, which pretty much defeats the purpose of it being waterproof. Plus, it’s just uncomfortable to walk on – you’ll feel every uneven spot.
I put down some coretec lvp in my house right before moving in… I was in such a rush to meet our move out / move in date that I didn’t have time to level out the subfloor completely, just in a few areas. 5 years later and still no problems. It’s pretty durable stuff, but I can’t vouch for other brands.
‘t forget to use underlayment!
I am about to remove half of my LVP because the individuals who installed it did not properly level the subfloor.
My floor cracked and split after about a month due to an inconsistency in the subfloor. I currently have a split right in the middle of my living room. I really wish I had taken the time to level it properly.
It seems like a seam should have been smoothed out
Quick answer: yes. Longer answer: also yes. If your floor is not completely flat, the flooring will not be installed properly and the seams will likely fail. While being level is not crucial, having a flat surface is essential. I’ve noticed that hardwood is more forgiving when it comes to minor imperfections because of its rigidity when nailed or glued down.
Sub floor should not necessarily be perfectly level, but it needs to be flat, ideally within 1/8-3/16” in a 10’ circle
In simple terms, anything less than 3/8th of an inch thick will show imperfections underneath. With my large dogs and an uneven floor, I opted for ceramic tile that resembles wood. I used a 1/4″ tile backer set and leveled with a 3/8th inch notched trowel. It cost me around $4 per square foot to do it on my own…
No
Of course! If you skip this step, any uneven surfaces could lead to the seams breaking or splitting. Want to hear a funny story about it? 🤣
Make sure you also invest in a good quality flooring. The cheaper options can end up being more trouble than they’re worth.
It all depends on how bad the flooring is and its quality. A little bit of flex won’t cause any issues, but too much of it can make it come apart. Watching some videos can make it easy to level.
Sure, here is the rephrased text: Nah
There’s a distinction between level and flat. It also depends on the direction in which you’re laying the planks. In simpler terms, if the floor is sloped but flat, it’s not level but it’s okay. Having areas that are more like depressions can lead to issues with seams separating.
If you’ve ever walked on a floor and noticed a soft spot, there you have your explanation.
Absolutely
Really hit the nail on the head when he said it. Does it need to be perfectly “level”? Not necessarily. Does it need to be flat? Absolutely.
If you want to do it again, then yes, it should be done.
I was debating between different options for my basement floor. Since it’s an older house with a slight slope toward the floor drain, I ultimately chose carpet tiles. They are easy to install with double-sided tape, can be replaced easily, and the rubber backing is ideal for cement floors.
Floating flooring products such as click-lock LVP are often advertised as the quick fix, but the truth is, it can be much more challenging to install a floor that eliminates bouncy spots in an older home compared to using a product that can be nailed or stapled down, like engineered or solid hardwood.
What are some top brands to use to avoid tiles from separating or popping up?
YUP
No levels, just flat surfaces.
Right?
Definitely, if not, you’ll notice it when walking, and eventually the LVP will begin to crack at the interlocking points.
So, are you looking to avoid things moving around?
