Casement Window FAQs
How long does casement window installation take?
Most individual casement window replacements take 1 to 2 hours per window. Whole-home projects are typically scheduled over one to three days depending on the number of windows and opening conditions.
Are casement windows energy efficient?
Yes. Casement windows compress tightly against the frame when closed, which helps reduce drafts and air leakage compared with many sliding window styles.
What warranty does Cosello provide?
Cosello Construction backs window installation labor with a 2-year warranty. Manufacturer product warranties vary by window brand and series.
