Estimated expansion is generalized in the table. Depending on your local climate, house particulars, wood species, etc. expansion will likely differ. For example, if one lives in a very dry or very wet climate expansion (and contraction) will have particular values, that is - joint change distances. Here's a couple of solutions, given the difficulty of exactly estimating joint change: 1. use a slightly wider skirt molding and hope it's wide enough 2. you could also use wider skirt molding and just observe floor movement. If a crack is seen then fetch some quarter round, stain it or varnish it and tack it into place. Oh, and remember to let the wood cure for a couple of weeks in the room to reduce change after install.

We installed 2600 sf of Happy Feet Pinnacle LVP in our new build and am very happy with it. i had read through this group many times prior but decided with grown kids it was more important to us to have a matte look and low maintenance than risk wearing out our socks. I definitely prefer the feel of natural wood under bare feet but this LVP is not wearing out our socks or our bare feet. So far it feels like a great decision. interesting anecdotal observation - when in our old house, which had hardwood throughout, when we laid out various LVP samples and left them there for a week, our dog stated laying on the Happy Feet sample section. Never the other samples. 🤔

@3onthetree - not sensitive. There simply was no reason to comment about the way my flooring was installed as being a “second rate DIY installation.“ People with expertise in a particular area should always inform people of applicable industry standards related to the subject matter of the discussion. That is one of most important aspects of Houzz. With that being said, people (professionals and laypersons) should also feel free to provide alternate ideas/solutions in a discussion - so long as the same are not (i) safety hazards, and/or (ii) in violation of any applicable laws/codes/regulations/etc. KF was simply providing an example of what she/he did to finish the baseboards in his/her home. While you may not like the way it looks because it appears to be crown moulding located upside down along a floor, there’s no reason to make a disparaging remark about it looking DIY. Simply stating that cove moulding is not supposed to be used for that purpose would have sufficed. The shot of “DIY” is pejorative - especially here on Houzz. The same relates to the comment I posted. Choosing to qualify “DIY” by adding “second rate” just further added to the negativity. If you read my comment, you’ll notice that I wasn’t even suggesting that the OP complete his/her baseboards in the manner mine have been. I simply made the comment in order to let the OP know that maybe his/her flooring will fit underneath the baseboard also - and if it does, it could be finished the way mine currently is. That’s all. I wasn’t taking a shot at you. I wasn’t being nasty. It kinda seems like you are the one who is a bit sensitive simply because I made a comment that contradicted yours. You said in your initial post that whenever carpet was removed and replaced with other flooring, moulding was required. Even if that’s the case 99%% of the time (I have no idea of how often it is or isn’t), that still means sometimes the flooring fits underneath the baseboard. In my case, it did - and if you read all of my last comment - you’d know that it didn’t really need the caulk line (which I realized after I scrolled through MANY photos of professionally installed baseboards with a tiny gap - around 1/16” is normal). The point of my post was just to share that with the OP (and others who may be interested) in alternative ways of finishing their floors/baseboard transitions. Many comments on Houzz are posted for the same exact reason. We all already know that ripping out your old dated honey oak cabinets in order to start with new ones is the preferred professional solution when someone has decided to install new granite/quartz/marble countertops. However, not everyone has the money (or inclination) to do that. So, people CONSTANTLY offer alternative ideas/thoughts/solutions on Houzz. Just because someone offers up a different idea which is not what the professional solution from a KD would be, does not mean that they should be told that their painted cabinets make their kitchen look like a second rate DIY update. Especially not when they haven’t even posted a photo of what their solution looks like. . . I spent some time looking into adding a tiny line of caulk when it was presented to me as an option - and as I’ve already stated, there are PROS who said it was fine. I also acknowledged that using caulk wasn’t an industry standard by making a joke about being “scolded” by people for doing it. I did so in order to let OP know that it wasn’t standard - and to try to avoid having someone feel the need to post a comment to inform me/OP that it wasn’t (obviously, my attempt at making fun of myself for doing something that wasn’t normally done didn’t work). I thought that if I called it out on my own as not being a ”professional” solution, that no one else would feel the need to do so. I also want asking/expecting/requesting ANYONE TO FAWN over my solution. So, I guess there’s no need for me to go join a FaceBook group - although I‘m not exactly sure what that means as I don’t use FaceBook - I can only assume that you‘re referring to people posting photos of whatever (family/pets/new houses/etc) which then can be liked by others (similar to posts on Houzz). I don’t ever go back to check on whether anyone “liked” one of my posts or not so. . . ??? I have read MANY comments on Houzz where people freely give legal advice to people in discussions - and MANY times that advice is not applicable to the situation and/or incorrect. As an attorney, I could jump in and post a comment every time this happens - informing everyone that, not only is the advice what someone professionally trained in the legal profession would give, but also add some type of comment that specifically belittled the person who gave the advice - but I don’t. Now, if someone is handing out “legal advice” in a manner which may cause an OP (or some future reader) to act (not act) in a manner which has the possibility of some adverse legal consequences, I will post a comment. When I do so, I ALWAYS try to do it in a manner which will not sound demeaning or make someone feel as if I am questioning his/her intelligence. I simply do my best to not insult anyone. You may not think that you wrote anything insulting - however (as I pointed out above), telling someone that the his/her moulding choice looks “DIY” or that her floors have been finished in a “second rate DIY“ manner, is simply not being respectful/nice. Adding the those comments were not necessary in order to provide information for the OP (or anyone else). I’m not going to continue in some stupid/useless battle on here re: this subject. I’ve wasted more time on it than I should have already. The ONLY reason that I decided to post this comment (or my previous one) is because I really don’t understand why people say (write) some of the things they do on here. I just don’t feel like there’s any reason to make negative comments towards people/their ideas/their homes/their decorating choices. It’s kind of like when something goes wrong and immediately people jump to the conclusion that the OP was a cheapskate and hired a hack/purchased the cheapest materials he/she could find when there are no stated facts which lead to that conclusion. Negative/rude/disparaging comments are detrimental to Houzz because it stops many people from posting/commenting for fear of receiving the same treatment. With respect to your question asking me if I realize that the floor has to be taped - I assume that you mean this: Again - it wasn’t a “DIY” project - and as I already wrote - I wasn’t home when this was done by my flooring professional. I assume that he did it in a manner similar to what Uptown Floors has posted in the pro advice section re: causing baseboards. As to it being concave - I’ve never put my head down by the floor to study it - it looks “straight” and “finished” to me. There’s nothing to sand. It’s wide plank European Oak that was nail/glue assist installed so no laminate that’s been fiddled with to fit it underneath the baseboards. In the event you did not intend your comments to be negative/disparaging, then I truly apologize to you for writing this long response. I also apologize to the OP (and everyone) for interfering with the purpose of this discussion.

new floor is ripped up and he's now screwing the old floor down. i asked how he knows where the joists are (absent crawling in the crawlspace). he said from when the other guy cut open the floor he can tell where 2 pieces of plywood joined together and that should be over a joist. i asked if he could use stud finder and he said no cause is more metal under the house. i guess it makes sense but unsure it's really the way to tell where joists are. he's doing 2 rows of screws on each joist. sadly now in winter the floor isnt squeaking as much as summer. so my plan to walk all over it before the new floor went in will not be a good test. sigh. this guy is so much better than the other 2. he's doing the patch that should have been initially done because of the slope. maybe thats why the other 2 arent here.
