Frequently Asked Questions

Impact windows use laminated glass with an interlayer that holds fragments together when struck, protecting against hurricane debris and forced entry. Nonimpact windows use standard insulated glass, which shatters on impact. Florida's storm-prone climate makes impact-rated products valuable for wind-borne debris zones, while nonimpact options work for areas outside hurricane requirements.

HVHZ glass meets stricter performance standards required in High Velocity Hurricane Zones like Miami-Dade and Broward counties. It undergoes more rigorous testing for wind pressure and debris impact than standard impact glass. If your property falls within HVHZ boundaries, code compliance requires HVHZ-rated products rather than standard impact ratings.

Full window replacement makes sense when frames show rot, warping, or operational failure—casements that won't crank, double-hungs that won't stay open, or sashes with broken balances. Glass-only replacement works when frames remain structurally sound but panes are cracked, fogged, or you're upgrading to impact protection without changing the opening.

Casement windows seal tighter when closed because the sash compresses against the frame, reducing air infiltration during storms. Double-hung windows use sliding contact that can allow more air movement. Casements also maximize ventilation by opening fully outward, catching cross breezes—an advantage in Florida's humid climate where airflow matters.

Coverage specifics vary, but lifetime warranties typically include manufacturing defects like seal failure, glass delamination, hardware malfunction, and frame deterioration. Labor coverage for repairs is less common and adds significant value. Verify whether the warranty covers both product and installation labor, transferability to new owners, and exclusions like glass breakage from impact.

Impact patio doors endure more stress from frequent operation—sliding or swinging mechanisms, locks, and weatherstripping wear faster than fixed windows. Quality hardware and proper installation become critical. Impact-rated glass adds weight, requiring heavy-duty rollers for sliders and reinforced hinges for swinging doors to prevent sagging and alignment issues over time.

Existing frames rarely accommodate impact glass without modification. Impact-rated doors are heavier and thicker, requiring reinforced frames, stronger hinges, and impact-rated hardware to meet certification standards. Retrofitting typically costs nearly as much as full replacement while voiding impact ratings, making new door systems the practical choice for storm protection.

Price differences reflect product quality tiers, installation experience, warranty coverage, and business overhead. Low bids often use builder-grade windows with limited warranties and subcontracted labor. Higher quotes may include premium vinyl formulations, fusion-welded corners, multi-chamber frames, and direct employee installers. Installation quality affects long-term performance more than initial cost.

Both matter, but glass area is larger so glazing choices have greater impact. Low-E coatings reduce heat transfer, argon gas between panes improves insulation, and laminated glass in impact windows adds a thermal barrier. Frame material and design affect edge-of-glass performance—multi-chamber vinyl and foam-filled frames reduce conduction through the frame itself.

Impact doors are available in traditional panel designs, modern flush styles, and configurations with decorative glass inserts that match various architectural themes. Frame profiles, color finishes, and hardware selections adapt to Mediterranean, Colonial, Craftsman, or Contemporary exteriors. The impact-rated construction sits behind the visible design, not dictating appearance.

Installers remove old units, inspect rough openings for rot or damage, shim new windows level and plumb, secure frames to structural framing, and seal gaps with low-expansion foam and flashing. Poor shimming causes operational binding, inadequate sealing allows water intrusion, and missing flashing leads to frame rot. Each step directly impacts whether windows last decades or fail early.

Whole-house replacement qualifies for volume pricing, ensures consistent appearance, and maximizes energy savings immediately. Phased replacement lets you budget incrementally and prioritize problem windows—south and west exposures that overheat, leaking units, or street-facing windows for curb appeal. Storm preparation may justify prioritizing impact windows on vulnerable elevations first.
