Window cleaning in Highland Village.

Highland Village grew early. The town was a few hundred people in 1970 and a few thousand by 1990, and the housing traces that line: sixties lakeside originals, seventies and eighties neighborhoods from just after incorporation, then Highland Shores, a master-planned community of more than sixteen hundred homes whose first houses went up in 1985.

That age is the defining fact for glass here. A window installed in the mid-eighties has been through forty Texas summers, and insulated units of that generation weren't built to last this long. Seal failure is the result, and it looks like permanent haze or visible moisture between the two panes — something cleaning can't fix, because the problem is sealed inside the unit.

The good news is that it's a replacement of the glass unit, not the whole window, and we do that work ourselves. Worth knowing before anyone talks you into replacing an entire frame that's doing fine.

Alongside that, the town has big shade trees — one of the nicer things about living here and one of the harder things about keeping glass clear. Combined with Lake Lewisville along the north edge, it's the same pairing as Flower Mound: organic debris from above, mineral haze off the water.
