Florida Coastal Wind Zone
Wind Zone Requirements for Largo Homeowners
Largo is in a Florida coastal wind zone where all replacement windows and doors must use Florida Product Approval–certified impact glazing. Your exact design wind speed depends on your parcel's distance from the water and your specific street address — coastal and waterfront locations often carry higher design pressures than homes set back from the shoreline.
We pull your parcel's official wind speed map designation from the Florida Building Commission database before recommending any product. This step matters: a window rated for an inland address may not meet the required design pressure for a waterfront property on the same block.

Local Questions
About Largo Impact Window Installations
Does Largo have its own building department or go through Pinellas County?
The City of Largo has its own building department for properties within incorporated Largo. We know which office applies to your address and manage the entire permit process on your behalf, including scheduling and attending all inspections.
What makes window replacement in older Largo homes different from newer construction?
Many Largo homes from the 1960s and 1970s were built with non-standard rough opening dimensions using jalousie or early aluminum slider windows. These openings often require custom window sizing or rough opening modifications before a modern impact unit fits properly. We assess every home individually so you get the right product for your specific construction — not a generic quote.
Common Questions
Impact Windows & Doors in Pinellas County
Do Pinellas County impact windows need to meet HVHZ standards?
Yes — properties on Pinellas barrier islands (Clearwater Beach, St. Pete Beach, Treasure Island, Indian Rocks Beach, etc.) fall within Florida's High Velocity Hurricane Zone and require HVHZ-rated windows and doors. Inland Pinellas locations still require Florida Product Approval–certified impact glass, but the specific wind load rating depends on your exact address. We'll confirm your zone before recommending any product.
How does the Pinellas County building permit process work for window replacement?
Pinellas County requires a building permit for window and door replacements. We handle the entire process — submitting drawings and product approvals to the Pinellas County Building Department, scheduling the inspection, and walking the inspector through the completed work. You don't need to interact with the county at all.
How does the salt air in Pinellas County affect window frames?
Salt air accelerates corrosion in standard aluminum frames. All of the impact window and door products we install in coastal Pinellas locations use marine-grade anodized aluminum or premium vinyl framing specifically engineered for saltwater environments. PGT WinGuard, Simonton StormBreaker Plus, and CWS products all carry salt-air ratings appropriate for Gulf Coast and Tampa Bay installations.
