New subfloor and a host of other headaches

Sunday, November 21st, 2010 @ 7:53 pm | Politics

Whoever built the addition on the house cut every corner possible. Not only is it poorly heated (the ducts run through a dirt crawlspace) it’s poorly insulated. The subfloor consists of 1/2 inch OSB and that was the only barrier between the living room space and the frozen Iowa earth below. The previous owners also sealed off the entry to the crawlspace so insulation between the joists would require sawing an access hole in the old flooring. With that in mind we opted for a quarter inch of foam underlayment with another layer of sheathing screwed down on top of it.

    It can’t be that bad if you have a hot chick helping you.

    Yeah, Ellen, but this means that you’ll be seeing all of Mike’s carpentry skills, in action, live, where he can’t hide anything! ๐Ÿ™‚

    Couldn’t you have simply pulled one sheet of OSB to gain access? Then you put down your insulation, climb back out, and replace the OSB.

    And please tell me that they at least left air-flow vents, to prevent moisture buildup.

    Of course, the big question is: what goes over the new sub-floor? Brick fireplace, beige walls, so the right answer is: Bellawood Santos Clear Finish Mahogany at a mere $7.29 ftยฒ! Cha-ching!

    It’s completely sealed. No airvents. Pulling up a piece of flooring and crawling down was an option but the lack of air vents meant that if there was any moisture buildup there was the potential of the insulation getting soggy and losing whatever R value it had. I really wasn’t too keen on crawling around under the house either. As of today the sheathing is all screwed down and Randy’s Carpets is scheduled for a December 2nd install. And not a moment too soon!

    Carpets? Carpets? [sigh.] ๐Ÿ™‚

    Ellen! Make him put down hardwood flooring! You can get area rugs for the places you want them.

    Her decision! I’m just Miguel, the cheap day laborer she picked up at the Home Depot parking lot.

    Ah, RAndy’s carpets.

    Man, I miss living in Iowa.

    Not for the carpet merchants, exactly, but it’s another taste of home.

    How interesting that you picked an obviously Hispanic name. Racist! ๐Ÿ™‚

    If it makes you feel better, most of the house is hardwood, Dana. Keep in mind we’re trying to warm up this room as much as possible, so carpet (with a big fat R4 pad) it is.

    And don’t feel too bad for Miguel. He’s getting lots of help and is getting paid very well in tortillas.

  13. Dana Says:

    Well, load up those tortillas with some of the peppers Miguel has shipped out this way; the room will stay plenty warm.

    I’m doing a Bedroom expansion. Making two BR’s into one.

    Big pimpin’. Are you going to put a revolving circular bed in there?

  16. Yorkshire Says:

    “Big pimpinโ€™. Are you going to put a revolving circular bed in there?”

    Then how could I “corner” somebody there ? ๐Ÿ˜Ž

  17. Yorkshire Says:

    Was the addition subject to a building inspector since the house was expanded. When I did my addition, I need a strucural and electrical inspections.

  18. Yorkshire Says:

    We had a case around here where the inspector certified a house that would have caved in at any minute. The inspector was sued for not making the builder follow code. He lost his inspection license for six months. He was the same idiot that looked at concrete that had set already and said it looked like it was placed too stiff (not enough water in the mix)

    Suggestion for the underfloor insulation is drill about a 2 to 3 inch hole in the floor and pour packing peanuts down there. Hook your vacuum hose to the ezhaust and blow them to the sides.

    Yorkshire is an engineer!

  20. Dana Says:

    You said that there were no air vents at all in the crawl space, which can’t meet code. I have seen some people “conceal” their air vents by leaving the sides of a few bricks unmortared so that air can circulate; is it possible that whoever built this addition did that?

  21. mike g Says:

    There was one single air vent to the crawlspace and that has been sealed up. It was actually the old basement window that faced the back of the house where the new addition now stands. Because of the sealed nature of the crawlspace there is a radon mitigation system in place and I’m guessing that was installed to meet code (such as it was at the time). Now, that window was sealed off with plywood and caulk so it wouldn’t take much to open it up. I’m just not too keen on crawling around down there at this time of the year. Still, I’ll take the cold ground over freakin’ spiders any day!

  22. Dana Says:

    Nothing quite like dealing with the problems from someone else’s work! ๐Ÿ™‚

  23. mike g Says:

    Fuck it. I’m just going to drill fifty holes in the floor and start pumping expanding foam down there until the whole addition floats off the foundation.
