Window replacement costs in Baton Rouge

Baton Rouge is mostly a cooling town. The airport reaches 90 degrees or more on about 96 days in a typical year, and the low dips to freezing on only about 18 nights. Its cooling-degree-day total runs nearly twice its heating total. So for a window here, keeping summer heat out is the bigger job than holding winter heat in.

Rain is the other constant. The airport collects about 62 inches in a normal year, and about 19 days bring an inch or more. Every one of those days tests the seal between the frame and the wall.

Louisiana writes one construction code for the whole state, and it's fairly new. The Louisiana Uniform Construction Code Commission was set up in 2005, and its first statewide codes took effect January 1, 2007. Today the state uses the 2021 International Residential Code, in effect since January 1, 2023, and the 2021 International Energy Conservation Code, in effect since July 1, 2023.

That history matters in Baton Rouge because the median home in the metro dates to 1991, per the Census Bureau. More than half the homes here went up before Louisiana had a statewide code at all, so an original window here was built to whatever local rules applied at the time.
