Contract & 50% Deposit
Deposit reserves your inventory and your installation date. In-stock inventory at Windows Stock Market is first-come, first-served — reserving early protects your price and timeline.

Installation Day (1–2 Days)
Old windows are removed, new impact windows installed per NOA or FL# installation specs, every opening sealed and caulked, and the site cleaned up completely. Old windows removed and disposed of at no charge.
Final County Inspection
We schedule and attend the county inspection. Inspector verifies installation matches permit documents. Certificate of Completion closes the permit — your windows are legally hurricane-certified.

After permit close, order a wind mitigation inspection (OIR-B1-1802 form). Submit to your insurer. Florida law mandates 25–45% windstorm premium discount for Opening Protection Category A.

Day of completion
Final walkthrough with crew. Confirm all windows operate correctly and all exterior caulking is complete.
Within 3–7 days
County final inspection scheduled. Inspector confirms NOA or FL# compliance. Certificate of Completion issued.
After permit closes
Order wind mitigation inspection ($75–$150). Inspector completes OIR-B1-1802 form in 1–2 hours.
Submit to insurer
Submit OIR-B1-1802 to your homeowners insurance carrier. Request windstorm premium discount review.
Discount applied
25–45% windstorm premium reduction at next renewal or mid-term endorsement. Savings recur annually.
ROI note: On a $5,000/year insurance policy with 35% windstorm discount, you save $1,750/year. A $12,000 installation project pays for itself in 7 years purely from insurance savings — before accounting for home value increase or storm protection.
Red Flags When Choosing an Installation Contractor
Quote doesn't include the building permit — unpermitted installations are illegal and cannot get wind mitigation inspection
Won't provide a current certificate of insurance — general liability and workers' comp, before anyone touches your home
Asks for more than 50% upfront (standard is 50% at signing, 50% at completion)
Cannot show the NOA or FL# Product Approval number for the product they're proposing
Verbal quote only — prices change at contract time without documentation
No single point of accountability — nobody owns the job from measurement to final inspection
Frequently Asked Questions — Impact Window Installation
How long does impact window installation take in South Florida?
Physical installation: 1–2 days for a typical 10–15 window South Florida home. A 10-window single-family home takes 6–8 hours. The total project timeline (from contract to final inspection) is 3–6 weeks with in-stock inventory, or 12–22 weeks with custom-ordered windows. The permit wait is typically 5–12 business days depending on county.
Do I need a permit for impact window installation in South Florida?
Yes — all window replacements require a building permit in every South Florida county. The permit must be pulled before work starts. Vieser Construction coordinates the entire permit process — engineering drawings, submission to the county portal, and final inspection coordination. Unpermitted installations cannot pass wind mitigation inspection and may require removal.
What happens on impact window installation day?
Your installation starts early (typically 7–8am). Interior surfaces are protected with drop cloths, old windows are removed one at a time, new impact windows are installed with approved fasteners per the NOA or FPA installation specs, sealant is applied, and the site is cleaned up completely. Old windows are removed and disposed of at no extra charge. An adult must be present for access.
Does someone need to be home during impact window installation?
Yes — an adult must be present on installation day to provide access to all areas being worked on. The county final inspection also requires someone to be home. You can continue your normal routine during installation — crews work room by room and the disruption is minimal.
How soon after installation can I claim my insurance discount?
After the county permit closes (Certificate of Completion issued), order a wind mitigation inspection ($75–$150, takes 1–2 hours). The inspector completes Form OIR-B1-1802. Submit this to your insurer — the discount applies at your next renewal or mid-term by endorsement with some carriers. Florida Statute 627.0629 mandates the discount.
