What Makes a Window Installer Truly Licensed and Insured?

Why Licensing And Insurance Matter More Than A Sales Pitch

A polished estimate does not tell you much about whether a contractor is actually qualified to work in your home. A bad install can lead to drafts, leaks, rot, and claims that nobody wants to own later.
