Pocket Door Insulation

My home has 3 pocket doors whose open track areas I have caulked well best as I can from the door jams without removing the track or framing around  it.  I believe I should attack the remainder of the leaks from the attic and from the basement.   Are there any folks out there who might share their thoughts on the recommended methodology for best doing this?  Thanks much in advance.  John Harper

Be a Little Like a Used Car Salesperson

Used car salesmen get a bad rap, and there are good reasons for that. But I think the home performance community can learn from them in some important ways. I say that as someone who once had a serious case of buyer’s remorse, but got over it.

When I first moved to California I was working at an independent bookstore in Berkeley, and I liked the idea of not having a car. But after a year I realized that I couldn’t get everywhere I wanted to go in a timely manner on BART (Bay…

PED's for an HVAC Technician?

An acronym for what is synonymous with all that is bad with the American Pastime, Performance Enhancing Drugs (PED's) have been proven to inflate a ballplayer's performance.  Most important in contract years, a player's performance is measured in specific statistics.  So, what if there was a pill, or cream, that an HVAC Technician or Salesperson could take to inflate their numbers.  Make them perform at the top of their field and get them the highest pay in the industry?  Would you take it?…

Modernizing the Residential Utility Disclosure Ordinance in Chicago

Back in the ‘80s, the Center for Neighborhood Technology and others helped the City of Chicago pass a residential utility disclosure ordinance that required the disclosure of heating bills when residential properties are sold or leased in the city. Why? Heating expenses constitute a significant home expense, and it’s important for consumers and Realtors to have access to this information.

Until now, complying with the ordinance could take up to two weeks: a Realtor submitted an…
