A house built around 1973 was framed for a lighter, single-layer door and a lighter opener than what's standard now. Over fifty years, those original jambs and headers have usually been drilled into more than once - for a replacement opener, for added weatherstripping, sometimes for a second spring conversion. By the time a new install happens, the header often has more holes than solid wood left to anchor into. That's a Highland Park problem more than an Euless-wide one, since most of the rest of the service area is newer stock built after today's framing and insulation standards were already common. Add the climate: this region sits in a severe heat band, and on an older header that's already stressed from decades of hardware changes, summer expansion and contraction loosens lag screws faster than it would on newer framing. We check header condition before we quote anything, because a new door bolted into a tired header doesn't hold its alignment, and that shows up as a door that won't seal or a track that walks out of plumb within a year.
