    Michael, Are you going to do the work? You can be sure there is lead on that old siding. This is a big expensive job you are planning. Do not do any work, just to get by. Think about the ...

    Thank you, Martin. I am plan on having another insulation contractor to come out and assess the current situation. I did not crawl throughout the entire attic to check for moisture/mold evidence ...

    Ilona, One more point: If the roof sheathing above the triangular attic behind the kneewall is moldy, that's evidence that there is a significant air leak from your interior space into the attic. ...

    Ilona, Even if your local code authority allows the type of installation you have, doesn't mean that your insulation contractor didn't screw up the job. If you have enough condensation on your ...

    C.L., Q. "Is there any metric by which to measure the efficiency of electrically heated bath floors?" A. Yes. The metric is called "efficiency." It describes the conversion of electrical ...

    Brian, Huber (the manufacturer of Zip sheathing) doesn't specify fastener type -- even staples are allowed as long as the staples are "code approved." As Malcolm noted, most contractors would ...

    It sure seems like it is probably permeable, but didn't know if specifics were known for products like this of that age. That's a good reference - thanks for sharing and the feedback!

    Martin, Our house does not have any roof overhang, the roof ends at the outside walls. Was told by multiple contractors that I would need to cut into existing roof to add rafters and create ...
  • Michael Grundvig | Apr 24,2018 12:14 AM EDT
    Thank you all for the input, I really appreciate it! Sadly, no refund is available. I'm pretty disgusted with HVAC contractors around here in general. I've had a heck of a time getting someone to ...

    Fasteners anywhere near the exterior of a building should be galvanized. What's the downside? They aren't much more a box. Just watch overdriving, it makes a big difference in how the ZIP performs.

    Brian, What does the siding manufacturer specify? Also, ZIP has an integrated WRB.

    Thank you, Dana! Yes, I agree. It sounds as though you probably remember (though other readers may not) that I was posting on someone else's thread last week about trying to figure out the right ...

    If the furnace is going to be replaced it's a once in 25 years opportunity moment to right-size it for higher comfort, less noise. Even with cheap gas, at cheap electric rates and temperate ...
  • Martin Holladay | Apr 23,2018 05:26 PM EDT
    Ilona, There are lots of uncertainties here. You never explained why you (or your contractor) decided that it was impossible to install vent openings at the bottom of the roof slopes (either at ...
  • Tyler Davis | Apr 23,2018 04:46 PM EDT
    Thanks for the replies. After thinking about this for a day, I came to my senses and realized that spending $1500 on a new heat pump dryer is silly, given the poor engineering and shoddy ...

    Martin, assuming the worst and the contractors unwillingness to remedy the problem, would you say that I should have the cellulose removed from the slanted rafters bays? It would leave me without ...
  • | Apr 23,2018 03:21 PM EDT
    Martin! Thank you for the response and this site, it had been a tremendous resource. Sorry about the nickname. I'm Brian. I have read and reread that article and it has been my baseline but ...
  • Martin Holladay | Apr 23,2018 03:09 PM EDT
    Ilona, Your story is one more example (if one is even needed) of why halfway measures -- even measures that "usually work" -- are so risky for both the contractor and the homeowner. It just takes ...
  • | Apr 23,2018 03:03 PM EDT
    Again, thank you for your time and advice, Martin. Very much appreciated.
  • | Apr 23,2018 03:02 PM EDT
    Thank you, Martin, just saw your response regarding gable vents. I realize the drawback but desperate times call for desperate measures. Absolutely agree about not cutting corners and felt I was ...
