Virginia Uniform Statewide Building Code Rules for Window Replacement

When A Window Swap Becomes A Code Issue

Permits, Scope, And What The Inspector Actually Cares About

How long does window installation take? For a typical replacement, a single opening may take only a few hours, while a larger project can stretch across a full day or more depending on access, trim work, and whether any hidden rot or framing repair turns up.
