The entire job was fraught with incompetence and unprofessional behavior. What was supposed to be a three-day job to add insulation and seal the crawl space turned into a seven-month headache. They made big mistakes with the work, for example, forgetting to air seal an entire wall plate in the attic and failing to insulate all the rim joist bays. Luckily, I caught the errors and had them fix the problems. Their work was pretty shoddy. For example, the crawl space insulated door they built fell apart in under two weeks. Further, they created a huge mess in the crawl space, and just covered it all up with a vapor barrier. My job took nine separate visits, and they were never on time. Nine visits, late every time. And, I'm not even counting the four appointments in which they blew me off entirely with no phone call. My work qualified for two rebates, one with the town and one with my utility. This Efficient House messed up BOTH forms, which could have cost me $265. Fortunately, the town was understanding enough to allow them to re-submit, and the company ended up paying the utility rebate since it was their fault for messing up the form. If you have a modest home and a modest budget, do not hire this company. Every excuse for them being late or not calling me back revolved around them being busier on bigger jobs. I heard time and time again that they were wrapping up work at the local university or needed to take care of another "big client." We were obviously a low priority for them, especially all the appointments to fix their mistakes and clean up their mess. In sum: They made big mistakes with the work, they created a huge mess in the crawl space, they were never on time, they blew me off entirely on four appointments, they messed up the town's rebate form, they messed up the utility company's rebate form, they lied to me on several occasions, and they treated me with disrespect. read more
