Vinyl vs. Fiberglass Windows for Orange County Homes
Vinyl windows cost less (about $700–$1,500 installed) and are very energy-efficient, making them the most popular choice in Orange County. Fiberglass costs roughly 30–60% more (about $1,100–$2,200 installed) but is stronger, has slimmer frames, holds dark colors better and handles heat and coastal conditions with less expansion.

Which should you choose?
For most whole-house replacements on a budget, quality vinyl is the best value. Choose fiberglass for dark exterior colors, large windows, strong west or south sun exposure, or when you want a premium look that lasts. Near the beach, both outperform old aluminum — just make sure the hardware is stainless.
