Understanding Retrofit and New Construction

If you are also sorting out how to choose energy-efficient windows for humid climates in Mandeville LA, the same fundamentals apply, and we will tie them in where it counts.

Two installation paths, explained

With retrofit, the old frame stays, the new unit is measured to fit inside it, and the crew focuses on air sealing, shimming, and tying into your interior trim.

Local Climate Considerations

Local factors that push toward one method or the other

Retrofit can be a strong performer in Mandeville if the original frame is intact and the perimeter is air and water sealed to spec.
