One more pic.

thanks!

Did you turn off the air conditioning while you were gone, as well as the water?

No - the air conditioning has been on. Is that bad?

I don’t know for certain, but I’ve heard that water damage is covered by insurance unless it’s due to neglecting an issue for a long period of time. I’d call your agent to confirm.

Crawlspace, slab, or basement?

There is a basement underneath.

My sump pump failed and basement flooded; my insurance agent recommended a good company to remediate (big fans brought in to dry out the area). Talk to your agent to understand your deductible and what they will cover so you can decide if you want to file a claim. Continue to take pictures or video especially when the source of the leak is identified, so you have documentation of the problems. Good luck!

Yes we did. 100% sure. I turned it back on when we came home today.

Backflow?? https://en.m.wikipedia.org/wiki/Backflow

‘The floor is wet’ floor of the cabinet or the room floor?

The floor of the cabinet.

Must be water from the p trap but that doesnt seem like enough water to cause this. Line the floor if the cabinet with paper towels and run water through to see if the trap is leaking.

I’ve had that happen and sometimes the floor will go back after it dries out. You may want to get a dehumidifier.

That’s what I’m hoping. I have one going right now. Thanks.

It looks like it's been leaking here.

It seems odd that you would see this while you were gone and water was off though.

I usually like to keep a plastic tray with a deep lip under the sink. It protects the cabinet (and floor) and also makes it more clear when there is a leak - because you can see the water in the tray.

Cheap protection.

BTW: Other places to look are the dishwasher and the ice maker connection for the fridge.

It looks like the damage is in front of the sink - so you could probably rule out the fridge.

How did you turn your water off (at the main shut off or at the appliances)? Did you drain the pipes or just turn off the water? Did you turn off the water heater?

First, water damage doesn’t need to happen where the water is leaking. This is especially true if there is a moisture or vapor barrier under the floor. We had a floor ruined from a leaking ice maker and the damage appeared 15’ away from the refrigerator.

Next, this doesn’t look like damage from a leaking trap in a vacant home.. It looks like damage from a leaking supply line or open window/door.

Hi everyone. Thanks for all the comments. Plumber came fast and it is the dishwasher. A constant drip even after the water was shut off (they said there is reserve water that stays in there). It was probably leaking when we used it before we left on vacation and we didn't know it. Thank god it went into our basement in the unfinished storage area - woo! Hardwood floor guy is coming now to take a look at the damage and THEN I will call my insurance company. My white oak hardwood floors are only 5 years old and on our entire first floor. Fun fun. :(.

It seems odd that you would see this while you were gone and water was off though.

Maybe there was a backup in the city sewer line? That is the only thing I can think of to explain it. Ask the neighbors if there was an event??

With the water turned off the system still can have 60psi. And if there's a second floor the volume from everything in the supply lines above the level of the leak can drain.

Dehumidifier and a fan blowing across the area should save the floor - but let us know what the floor guy had to say, please!

We had a leak in our dw pump that was only discovered when our floors started warping. It took a year to get 80% better, after a few years we sold and it had dried enough that no one noticed.

WOW!!

So sorry that this happened to you!

That didn't happen over a weekend. That's an extended leak, over time. Which your insurance may end up not paying for, once they dig into it. Only acute water leaks, like the water heater let go, get paid for by insurance. Chronic ones are ascribed to unperformed maintenance, and they weasel out.

Yep, from the color of the sub floor it's been leaking for a long time. When you left for the week and shut up the house the humidity levels spiked cupping the hardwood floors. I'm guessing you turned off the A/C when you left, and a week without any doors or windows opening and closing, the clothes dryer running, bathroom exhaust fan running there was no way for humidity to escape.

The insurance company may give you a hard time but in the end I believe they will pay the claim. Some companies are better than others.

And then drop you................

"And then drop you................ "

It is a possibility and I was dropped by American Family Ins. after filing a claim back in the early 90's. I've seen others get a run around by American Family also, Now my present Insurance company, State Farm, has never given me a hard time even after a half dozen claims over the years. Total payouts on all the claims came to about $275K. It depends on the Insurance company.

HI all. We have Allstate. So far so good. Adjuster came out on Thursday and assessed everything. It will be covered and who knows until later if we will be dropped. It is what it is - we have no choice but to file. They were able to take granite off without damaging the backsplash tile but we will see if it lasts through installation. Cabinets were damaged and have been reordered. He said that if anything goes wrong when putting it back together, they will cover it. I have absolutely no idea when this started. Floors were not damaged when we left on vacation. We did leave the air conditioner on and the water off.

Also - a question: We had our old hardwood floor under the cabinets, because we decided to replace our hardwood floors with 4" after we installed our new cabinets a couple of years ago. Now he said they would replace the wood under our cabinets with plywood. Is that normal? Plus everything has to line up perfectly to get that granite and backsplash together "right" again.

Yes, I believe that would be fine, as long as the level is correct and it is quality plywood.

My cabinet installers had advised me to coat the remaining original flooring (some pieces were removed to patch in damage elsewhere), the few pieces of new wood patched in to support the cabs, and exposed subfloor well with poly to protect the wood in case of any future leaks. The gaps also would allow water to drain into the basement, which in that area is just the laundry with concrete floor and block wall, instead of it sitting there doing damage.
