Fall is in full swing, and many homeowners living in and around Manassas, VA are beginning to notice cold spots popping up once again. Summer often hides these issues, but once temperatures begin to fall, cold spots make themselves known in short order. It’s easy to assume that the problem is due to a faulty HVAC system, but this is typically not the case at all.

More often than not, cold spots or even entire rooms that are difficult to keep warm are the direct result of a leaky building envelope.
