Vinyl Windows vs Fiberglass Windows for Leesburg, VA Homes

How The Two Materials Compare In Real Use

What Vinyl Does Well, And Where It Can Fall Short

How To Decide Without Guessing

- Is the home exposed to strong afternoon sun on multiple sides?

• Is the project driven mainly by budget, or by long-term value?
• Will the windows need to satisfy historic or HOA requirements?
• Is the homeowner planning to stay in the house for many years?
