The general contractor is now saying “sometime next week”
Also, “engineered wood is more stable. A week or so is fine.”
If it buckles in the 1 year statutory warranty, that GC would definitely be getting a call from me.
Hmm, how would i know the warranty in my jurisdiction?
Also, do you think i should rip open these boxes and spread out the wood on/near the floor?
Separately, I’ve been pressing him to do the damn floor since the beginning of the project (the major goal of the project is to cover my eroding [probably asbestos] floor tiles), and he’s been putting me off, claiming the special color wood to match my existing trim hadn’t come in, yet. I’m about 95% sure he lied about that, because he wanted to wait and do the floor last. And “we can’t possibly do it due to not having the parts” is a compelling story.
It’s not all that compelling, because some of the floor tiles were going to take a long time, and he lied to me and said they’d unexpectedly come in sooner, when he’d actually changed the order to a similar tile. So when he wants something to move, “can’t get the exact color” is hardly an impediment.
I only learned the tile was different from the first batch (utility room and storage room) because i called the shop it was ordered from to check on something else, and they mentioned it. Oh, and the tile guys casually said, “once they all get dirty you won’t notice the difference”.
So it’s possible the woods has been sitting in his basement for two months.
This. I live in the north east. Summer is when we get humidity. In the winter interior air can be very dry. Right now the meters (mine, and one the gc just put here) say 70F and 53 relative humidity. I turned off the dehumidifier a couple hours ago.
A one year warranty is kind of the national standard minimum, but yes, look into that for your state. Your contract actually should specifically state what the warranty period is.
And YES, open the boxes and take off the plastic wrap in particular. At a minimum stack them crosswise with air circulation between each board. A fan would be a good idea for air circulation if you have one. I find this conversation humorous since I live in the intermountain west–we’re trying to get moisture content down, you’re trying to get it up.
That’s where my puzzle that couldn’t be assembled was made. 
I don’t have a contract with the floor guy. He’s a subcontractor for the general contractor. And i don’t really have a written contact with him, either.
Eta: the good news is, no plastic wrap. It’s just planks in cardboard boxes, loosely sealed by strapping. I can peek in and see the wood at the ends of each box.
If we are really concerned about acclimating floor product we stack the boxes up on dunnage and put additional dunnage/ straps between each successive layer.
We would not put a wood product in a location that has really uneven humidity. Our floor vendors will refuse to install on wood sublfoor (i e. Not basement) if its moisture levels are not within 2% of spec (I think 6%?). I have seen engineered hardwood installed in basements but we do not do it often. There is just so much great LVP and even high quality laminate out there now that can be used instead.
Your solution now is to choose the humidity you are going to keep the basement at, set the dehumidifier to that, and keep it there.
Hmm. My dehumidifier actually has a way to set it. I wonder how to do that. I haven’t done anything more than turn it on it off in a decade.
It’s a nice one, it even pumps water out a tube vigorously enough to send it up and out the basement window.
Sorry I don’t know a lot about residential dehus. Calgary is a pretty dry place, so most houses have humidifiers instead. We use industrial dehus for water restoration which are a different beast.
I would think most portable residential units would have a humistat dial that you set and cylces the unit off when you reach your target humidity (40%?). Might just be a numbered dial.
The biggest problem I am aware of is them leaking.
