What is different about impact window installation in Connecticut
Older housing stock means knob-and-tube, asbestos and undersized services surface constantly; budget for discovery work that newer-stock states rarely hit.
Owner-builder: Homeowners may permit work on a single-family home they occupy. Impact Window Installation generally requires a licensed contractor to pull the permit, even where owner-builder status is available.

Frequently asked questions
Do impact windows need a permit in Florida?
Yes. Replacing a window changes an opening protection assembly, so every Florida jurisdiction requires a permit with product approval numbers and attachment details for each unit.
Do impact windows lower insurance?
Florida requires insurers to offer wind mitigation discounts for approved opening protection. Have a wind mitigation inspection done after installation so the credit is applied.
