This post isn’t about energy-efficiency so much as quality workmanship. Over the last week, I’ve shown examples of dangerous spray foam application and dangerous water heater venting that we’ve uncovered. And here’s a couple more recent examples from the field where the installers just didn’t care about a quality installation. [Thanks to John Scipione and Patrick Herbert, of our Syracuse office, who stumble into “interesting” situations on an almost daily basis.] The wiring in these looks like some sort of abstract art. But it doesn’t look like the electrical work of someone paying attention to detail. If your improving the energy-efficiency of your home look for quality. At a minimum, follow these guidelines for choosing a contractor and look for certification and accreditation by the Building Performance Institute (BPI).
