comment Why do lag screws have the unthreaded body between the head and the threads?
My understanding is that lag screw's shaft matches the threads is because they have to be pre-drilled. Since you want the hole larger than need be, the shaft is the same as the threads is the same as the hole. Structural screws on the other hand--which can be used when allowed in place of lag screws--have a consistent shaft size throughout for easier driving since they don't need to be pre-drilled.

comment Should I use spray foam to insulate a basement?
I know that's true in theory...but given that we had mildew growing on concrete in our old basement, I'd still be paranoid that SOMETHING was growing inside the wall :)

@iLikeDirt...oh, true...good point about standing water. (though I think if I had standing water, I'd be paranoid and want to tear out everything below the water line anyways...)

comment Should I use spray foam to insulate a basement?
@EvilElf yes, sub-grade walls and floors are typically at that temp, but that temp tends to be too cold in winter (uncomfortable) and too cold in summer (allows for humid air to condense). The goal of the insulation is to separate the conditioned space from anything that is colder than the condensation point.

@EdBeal it's not the insulation that causes mold problems, it's how it's installed. If there are water problems, sheetrock by itself isn't ideal as it too can allow for mold growth.

Good answer. One note, though...it's hard to finish cement board. I'd suggest using a non-paper based sheetrock such as Densarmor instead.

does 'under house' mean a crawlspace? If so, you definitely don't want to do this.

comment Contractor not using thin set between sub floor and cement board
This could be one of those "manufacturer wants you to over-engineer to avoid any possible warranty complaints" v "real world practicality". In a way, both the manufacturer and your contractor could be right. If it's new construction, and the rest of the house seems to be constructed well, I think screws-only is just fine. In an old house, the mortar wouldn't hurt.

comment Is it about time to replace the water heater?
@ThreePhaseEel if one replaces the sacrificial rod regularly, a tank should last forever. But few people do, so yes, the end of life is pretty much synonymous with something corroding to the point of failure.

comment How can I attach normal framed walls in between concrete columns?
@Sparr how much concrete surrounds it? It's hard to say, but I have a hunch that the concrete was still a key part of the support there...not that a nail hole would have been in and of itself an issue, of course.

@Sparr I'm not an expert on industrial buildings, but are you sure they were steel supporting columns (vs say rebar?)

comment Should I add sand or more limestone crush to raise a patio with no gravel bedding?
@pythonstarter the catch with a slab under brick is that if you are in a freeze/thaw area, you're going to run into constant problems with cracked paver joints and subsequent water damage. Less of an issue with pavers, but if using pavers, there's no real need for the slab...a compacted base will work better (and is cheaper).

I have kids. I wouldn't trust having a non-tempered glass table top in our house. :)

I'd suggest replacing it with tempered glass.
