Window replacement costs in Columbia

Columbia summers are long and hot, and your windows feel every afternoon of them. The airport averages about 81 days a year at 90°F or hotter, and about six that pass 100. Sun on a west wall heats the glass and the frame, and a window that lets that heat through turns the room behind it into a hot box.

Winter is mild by comparison. The same airport averages about 46 nights a year at or below freezing. That balance is why glass here should lean toward blocking summer sun, more than chasing the lowest possible heat-loss rating.

The houses span decades. Over a third of Columbia-area houses are from the 1970s or earlier, and roughly one in eight from the 1950s or earlier. On an older house, the old window may be single-pane glass in a wood or aluminum frame, and the jump to modern double-pane glass is bigger there than on a 2005 house getting its first replacement.

Timing matters in a place this hot. A replacement crew opens your wall one window at a time, and every open hole lets the heat in while your air conditioning runs. Spring and fall make that easier on the house and on the crew. If you can, book the job before the 90-degree stretch settles in.
