A cracked impact window pane is alarming — especially during storm season. But broken glass almost never means you need a new window. In most cases, we replace only the damaged glass unit while preserving the intact frame, saving you 60–75% of full replacement cost.
Cracked or Broken Impact Glass: What Happened and What It Means
Impact glass is engineered to crack rather than shatter — that's the whole point. The PVB interlayer holds broken fragments in place, maintaining your home's weather seal until repair. When you see a spider-web crack pattern, that's the impact protection system working exactly as designed.
How We Replace Impact Glass Without Replacing the Whole Window
Replacing impact glass means sourcing factory-matched insulated glass units (IGUs) — two panes of tempered, laminated glass bonded to a spacer with a sealed air or gas cavity between them. The replacement IGU must match the original's size, thickness, and impact rating. We measure and order from Florida-approved manufacturers, typically taking 3–5 business days for standard sizes.
Factory-Matched Glass: Why It Matters for Code Compliance
Florida building codes require that any replacement glass in impact window openings meet the same Miami-Dade NOA or Florida Product Approval as the original installation. We only use code-compliant replacement glass and document the installation for your records and any future inspection needs.
Single-Pane vs. Insulated Glass Unit (IGU) Replacement
Emergency situations — after a storm or break-in — require temporary securing to maintain weather protection. We can temporarily board or secure openings the same day while sourcing replacement glass. This prevents interior water damage from the next rain event, which is often more costly than the glass repair itself.
