You should have it inspected by the original installer. They may want to call in the company to send out a professional inspector.

If I was to just take a wild guess I think you have a moisture issue somewhere.

we are on the water. But that’s why we did engineered wood not real hardwood. We were told that it would stable. The house has air conditioning as well so it’s climate controlled. We have de humidifiers but they really don’t run much.

Wood and water are rarely a good combination. LVT might have been the better solution.

Search engineered wood floors and delamination, chipping.

Engineered hardwood IS "real wood", It is slightly more stable than a sand on site BUT. You are not freed from moisture or the fluctuations of sand on site entirely. My guess is your in home conditioning and a fluctuation in moisture from date of install.. Engineered responds no differently than a sand on site flooring. It is WHY it sits in boxes in your home for at least several days prior to any full install. We have no clue in your home, conditions now, or at install. Swelling seems to be the issue..........................or maybe not.

Call the installer back, and check the humidity in your home. We have no clue if you are on a slab, a basement or a crawl space, either. All of which are factors in installation.

Incorrect installation. Some "floor guy" whacked that into place incorrectly and damaged the edge. This is why you use a tapping block recommended by the manufacturer, not a block of wood. There is no warranty claim with the manufacturer on an install issue. This goes back to holding the licensed and isured professional flooring installer accountable. Or, in the absence of a professional, you get to chase the handy guy, and probably pay for all new out of pocket.

Yep, ^^^^ installer screwed the pooch.

We are thinking installer error. What dose pooch mean ? Thank you

Screwing the pooch means failing utterly and often embarrassingly so.

It seems to be derived from military slang just like SNAFU did. Came into popular usage in The Right Stuff when there was an issue with a capsule being opened prematurely and whether the astronaut had "screwed the pooch"

in the World War I era, soldiers referred to goofing off and wasting time as “f**king the dog.” By World War II, the phrase evolved to mean making a huge mistake. It was softened to “screw the pooch” in 1950 by a Yale student, Jack May, speaking to his roommate, John Rawlings, who went on to work at NASA. The phrase became part of the cultural lexicon when Tom Wolfe included it in his book “The Right Stuff” in 1979, as John Rawlings introduced the phrase to the astronauts, and Tom Wolfe allegedly heard Gordon Cooper say it to Gus Grissom as Grissom was departing on a mission. Oddly, Grissom required a major rescue, and some believe he did, in fact, “screw the pooch.” The phrase made it into the 1983 movie of the same name. Jack May recognized it, as he invented the wording, and determined the astronauts must have heard it from his old roommate John Rawlings.

It’s just an expression that means the installer messed up -

Haha oh ok thanks

And unfortunately the manufacturer warranty will not help. This is something you need to get the installer to remedy.

My question is this a heated cottage for all seasons ? How close to the water are you ? Where are you? IMO wood floor is not a great choice at the cottage .

It’s totally heated and air conditioned. It’s a house. It’s about a half acre of frontage from the water. It’s not from humidity. We figured out the installer hammered it in way way to hard. It’s so tight it looks like it’s vinyl. He damaged the edges
