Bay window cost FAQs for La Mesa
What is the difference in cost between a bay and a bow window?
Bow windows generally cost more than bay windows of similar width because they have more panels (4-6 vs. 3) and a more complex curved frame assembly, which adds both material and labor.
Does adding a bay window require a permit?
Yes, in most San Diego jurisdictions, since a bay window changes the wall structure and adds a roofed projection. The crews we refer pull the permit as part of the project.
Can I add a window seat without much added cost?
A basic seat board close-out is standard in most bay window quotes. A finished bench seat with a hinged storage lid adds cost but is far more affordable when done during the original installation than as a later retrofit.
