"I hate French doors- they are almost always leakers. Over 95% of the time only the active door gets used. So, I recommend people take them out and put in a good quality door with one or two side-lights. If they need a larger opening I…"
"Another trick I've seen is to dedicate the bottom half of a cabinet as a vestibule/mud-room with a second air-lock flapper like Peter suggests. Obviously you'ed need to design some people access to clean it out occasionally, but…"

"Eliron, Please keep me in your loop; I too am looking at using a 50gal. Rheem hybrid heat-pump to do both dhw and space heating with a First Co. air handler. The Rheem will get it's power from a 9panal 2.12 kW PV system. The…"
"Again it bugs me that renewables gets the lions share of these credits when we all know that people save more energy and get a bigger 'bang for their buck' by implementing energy efficiency improvements. Energy Efficiency needs better…"
"What I've done for ceiling returns is had my sheet metal shop make a 16"x25" hemed cover(the most common return size here) with a 10.25" hole in the center for the duct blaster coller. I have two 2" pieces of thin…"

I think we took that class together. All his comments are good, but I think he missed the sump pump. As you know, the deal is to first keep it dry, and then to let it dry when it gets wet. There's nothing cheap about…"
"What an ugly picture!
Hey, I'm still struggling with my crawl space stemwall efflorescence. Did you take the guy, Rich Cowperthwaite's PG&E crawl space class? His suggestions to me: French Drain, Structural…"
I think we took that class together. All his comments are good, but I think he missed the sump pump. As you know, the deal is to first keep it dry, and then to let it dry when it gets wet.

I've put together scopes of work for another half a dozen and my numbers are in the $10K - $15K range. It's tough for people to swallow, but they're a lot of work. Have you checked those areas with a moisture meter? If I was closer I'd love to take a look. keep me posted and if I come up with anything I'll let you know.
What do you mean an ugly picture? Maybe that's why I'm still single.
