Impact Window FAQ

The cost of impact windows in South Florida typically ranges from $40 to $100+ per square foot, installed. For a standard-sized window, homeowners can expect to pay between $500 and $1,500 per window, depending on the size, frame material (vinyl, aluminum, or wood-clad), glass type, and design style. A full-home replacement for an average South Florida residence with 15 to 20 windows generally falls in the $10,000 to $30,000 range, though larger homes in areas like Coral Gables, Boca Raton, or Jupiter can exceed that significantly. Several factors influence the final price. Custom shapes, oversized openings, and high-performance Low-E coatings or laminated glass upgrades will add to the cost. Labor rates in Miami-Dade and Broward counties also tend to be slightly higher than in Palm Beach County due to stricter code requirements and permitting processes. At Florida Impact Windows & Doors, we provide free, no-obligation estimates so you can see an exact breakdown of material and installation costs specific to your home. It is worth considering that impact windows are an investment that pays for itself over time through insurance premium reductions, energy savings, increased home value, and the elimination of the recurring cost of putting up and storing hurricane shutters. Many South Florida homeowners find that the long-term return makes impact windows one of the smartest upgrades they can make.

Florida Impact Windows & Doors partners with several reputable lending institutions to offer flexible financing options that make impact window installation accessible to virtually every homeowner in South Florida. We offer plans ranging from 12 to 120 months, with competitive interest rates and, in many cases, promotional periods with zero percent interest for qualified buyers. Whether you own a single-family home in Pembroke Pines or a waterfront condo in Fort Lauderdale, we can help you find a payment plan that fits your budget. In addition to traditional financing, South Florida homeowners may qualify for the Property Assessed Clean Energy (PACE) program, which allows you to finance energy-efficient and storm-protection improvements through your property tax bill with no money down. PACE financing is available in Miami-Dade, Broward, and Palm Beach counties and has no minimum credit score requirement, making it an attractive option for many residents. Some local municipalities also offer rebate programs or incentives for hurricane-hardening your home. Our team walks you through every available option during your in-home consultation, including any current manufacturer promotions or seasonal discounts. We believe that protecting your family and property from South Florida's hurricane season should never be out of reach due to cost, and we work hard to make sure it isn't.

Absolutely. Impact windows are one of the highest-return home improvements you can make in South Florida. Studies and real estate data consistently show that impact-resistant windows and doors can increase a home's resale value by anywhere from $10,000 to $30,000 or more, depending on the size of the home and the scope of the installation. In competitive South Florida markets like Weston, Delray Beach, and Aventura, buyers actively seek out homes that already have full impact window protection because it means they won't have to make the investment themselves. Beyond the raw dollar increase, impact windows make your home significantly more attractive to prospective buyers. They signal that the property is well-maintained, code-compliant, and ready for hurricane season without the hassle of shutters. Homes with impact windows also appraise higher and often sell faster than comparable homes without them. Real estate agents across Broward and Palm Beach counties frequently cite impact windows as one of the top features buyers ask about. The value goes beyond resale as well. While you live in the home, you benefit from lower energy bills thanks to the insulating properties of laminated glass, reduced outside noise, enhanced security against break-ins, and the peace of mind that comes with year-round storm protection. When you factor in the insurance savings many homeowners receive, impact windows often pay for themselves well before you ever decide to sell.

Hurricane impact windows, also known as impact-resistant windows, are specially engineered window systems designed to withstand the extreme forces of a hurricane. They feature a laminated glass construction, which consists of two panes of tempered or heat-strengthened glass bonded together with a strong interlayer, typically made of polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA). This construction means that even if the glass cracks upon impact from flying debris, the interlayer holds the broken pieces in place, preventing dangerous wind and water from entering your home. In South Florida, impact windows must meet rigorous testing standards, including the Miami-Dade County Notice of Acceptance (NOA) protocol, which is considered the gold standard nationwide. During testing, windows are subjected to large and small missile impact tests (simulating debris strikes at hurricane-force speeds) followed by thousands of cycles of positive and negative air pressure to simulate sustained hurricane winds. Products that earn a Miami-Dade NOA or Florida Building Code approval have proven they can protect your home in Category 5 conditions. Beyond hurricane protection, impact windows deliver a host of everyday benefits that South Florida homeowners appreciate. They block up to 99 percent of harmful UV rays, protecting your furniture, flooring, and artwork from fading. They significantly reduce outside noise from traffic, construction, and aircraft, which is especially valuable near busy corridors like I-95, US-1, or Fort Lauderdale-Hollywood International Airport. And because they are always in place, you never have to scramble to put up shutters when a storm approaches.

Yes, impact windows come in different performance levels and classifications, and understanding the distinctions is important when choosing the right product for your South Florida home. The two primary rating systems you will encounter are the Miami-Dade County protocols and the Florida Building Code standards. Miami-Dade approved products (carrying a Notice of Acceptance) meet the most stringent testing requirements in the country, including both large missile and small missile impact tests. Products approved under the broader Florida Building Code may meet slightly different criteria depending on the wind zone and exposure category of your property. Within these standards, impact windows are further differentiated by their design pressure (DP) rating, which measures how much wind load the window can withstand. A higher DP rating means the window can handle greater wind speeds and pressure. Homes in High Velocity Hurricane Zones (HVHZ) like Miami-Dade and Broward counties require products with higher DP ratings compared to homes in inland or lower-wind-zone areas. At Florida Impact Windows & Doors, we help you select the correct rating for your specific location, whether you are on a barrier island in Palm Beach or in a suburban neighborhood in Davie. There are also distinctions in glass composition and coatings. Standard impact glass provides storm protection, but you can upgrade to Low-E (low emissivity) coatings that reflect heat and reduce cooling costs, tinted glass for additional glare reduction, or high-performance laminated insulated glass units that combine impact resistance with superior energy efficiency. Our consultants will walk you through all available options so you can choose the level of protection, efficiency, and comfort that best suits your home and budget.

High-quality impact windows installed by a professional team are built to last 25 to 30 years or more in South Florida's demanding climate. The laminated glass itself does not degrade over time and will maintain its structural integrity and impact resistance for the full life of the product. The aluminum or vinyl frames used in most impact window systems are engineered to resist corrosion from the salt air that is prevalent along the South Florida coastline, from Key Biscayne up through Jupiter and beyond. The longevity of your impact windows depends in part on proper installation and routine maintenance. Windows that are correctly installed with appropriate flashing, sealant, and anchoring will perform reliably through decades of hurricane seasons. Periodic maintenance, such as cleaning the tracks, lubricating hardware, and inspecting the weatherstripping, will help ensure smooth operation and optimal sealing. South Florida's intense sun and humidity can accelerate wear on seals and gaskets, but these components are inexpensive to replace and do not affect the structural performance of the window. At Florida Impact Windows & Doors, every installation is backed by both manufacturer warranties (which typically cover the glass and frame for 10 to lifetime, depending on the product line) and our own workmanship warranty. We stand behind our installations because we know that when impact windows are done right, they protect your home season after season without the need for costly repairs or early replacement.

This is one of the most common questions we hear, and the short answer is no, standard hurricane impact windows are not designed or rated to stop bullets. Impact windows are engineered to resist windborne debris during a hurricane, such as roof tiles, tree branches, and gravel propelled at high speeds. The testing standards, including the Miami-Dade large missile test (a nine-pound 2x4 lumber piece launched at 34 miles per hour), simulate storm debris, not ballistic threats. A bullet travels at far greater velocity and concentrates its energy on a much smaller point of impact. That said, impact windows do provide a meaningful layer of security against break-ins and forced entry. The laminated glass construction makes it extremely difficult for an intruder to smash through the window quickly. Even repeated blows with a heavy object will typically only crack and spider the glass rather than create an opening, because the PVB interlayer holds the fragments together. This buys valuable time for alarm systems to activate and authorities to respond. Many South Florida homeowners in neighborhoods across Miami, Fort Lauderdale, and West Palm Beach cite enhanced security as one of the top reasons they chose impact windows. If you need true ballistic-rated glass, that is a specialized product category with its own testing standards (such as UL 752) and significantly higher costs. For the vast majority of South Florida homeowners, standard impact windows deliver outstanding protection against hurricanes, break-ins, UV damage, and noise. If you have specific security concerns beyond storm protection, our team at Florida Impact Windows & Doors can discuss options that pair impact windows with additional security features.

The timeline for a complete impact window installation depends on the size of the project, but most South Florida homes can be fully outfitted in one to three days. A smaller home or condo with 8 to 12 windows can often be completed in a single day, while a larger residence with 20 or more openings, including sliding glass doors and custom shapes, may take two to three days. Our installation crews at Florida Impact Windows & Doors are experienced professionals who work efficiently without cutting corners, and we always aim to minimize disruption to your daily routine. The process begins well before installation day. After your in-home consultation and product selection, we take precise measurements of every opening. Your custom windows are then manufactured, which typically takes four to eight weeks depending on the product line and current demand. Once your windows arrive at our warehouse, we schedule your installation at a time that works for you. On the day of installation, our crew removes the old windows, prepares the openings, sets the new impact windows, seals and secures them, and performs a thorough cleanup. One important factor unique to South Florida is the permitting and inspection process. Miami-Dade and Broward counties require permits for impact window installations, and a county inspector must sign off on the completed work. Florida Impact Windows & Doors handles all permit applications and coordinates inspections on your behalf, so you do not have to navigate the bureaucracy yourself. From the moment you sign your contract to the final inspection approval, our team manages every step of the process.

Yes, a building permit is required for impact window installation throughout South Florida. This applies whether you live in Miami-Dade, Broward, or Palm Beach County, and it is true for both full-frame replacements and retrofit (insert) installations. The permitting process ensures that the products being installed meet the Florida Building Code requirements for your specific wind zone and that the installation is performed according to the manufacturer's specifications and local regulations. The permit application typically requires detailed information including the product specifications, the manufacturer's Florida Product Approval or Miami-Dade Notice of Acceptance number, engineering drawings or calculations, and a scope of work. In the High Velocity Hurricane Zone (HVHZ) that covers Miami-Dade and Broward counties, the requirements are especially stringent, and inspectors are thorough in verifying that every aspect of the installation meets code. Failure to obtain proper permits can result in fines, complications when selling your home, and, most critically, an installation that may not perform as expected during a hurricane. At Florida Impact Windows & Doors, we handle the entire permitting process from start to finish. Our team prepares all documentation, submits the application to your local building department, and schedules the required inspections once the installation is complete. We have deep experience working with building departments across South Florida, from the City of Miami to Boca Raton, and we know exactly what each jurisdiction requires. You should never have to worry about permits when you work with us.

Yes, impact windows can absolutely be installed in older South Florida homes, and in fact, upgrading older properties is one of the most common projects we handle at Florida Impact Windows & Doors. Many homes built in the 1950s through 1990s across neighborhoods in Miami Shores, Wilton Manors, Lake Worth, and throughout the tri-county area were constructed before modern hurricane codes were adopted. Replacing the original single-pane or non-impact windows with today's impact-resistant systems is one of the best ways to bring these homes up to current safety standards. Older homes can present unique installation challenges that require experienced professionals. The window openings may not be perfectly square, the surrounding wall construction might be concrete block, stucco over frame, or a combination of materials, and there may be non-standard sizes or shapes that require custom fabrication. In some cases, structural reinforcements or modifications to the rough opening are needed to support the heavier impact window assemblies. Our installation teams are well-versed in working with every type of construction found in South Florida's diverse housing stock, from 1920s coral rock homes in Coral Gables to 1970s CBS construction in Plantation. One concern homeowners sometimes raise is whether new impact windows will look out of place on a historic or architecturally distinctive older home. The good news is that modern impact windows are available in a wide range of styles, including single-hung, casement, awning, and picture windows, with frame finishes and profiles that complement both contemporary and traditional architecture. If your home is in a designated historic district, such as parts of Old Fort Lauderdale or West Palm Beach, we can work with you to select products that satisfy both the building code and any historic preservation guidelines.

Yes, installing impact windows can lead to significant reductions in your homeowner's insurance premiums in Florida. Under Florida law, insurance companies are required to offer discounts or credits for hurricane mitigation features, and impact-rated windows and doors are among the most impactful upgrades you can make. Homeowners across South Florida regularly report annual insurance savings ranging from several hundred dollars to over $2,000 per year, depending on their policy, carrier, and the extent of the mitigation improvements. To claim the maximum discount, you will need a Wind Mitigation Inspection performed by a qualified inspector after your impact windows are installed. This inspection documents the hurricane-resistant features of your home, including the window and door protection, roof shape, roof-to-wall connections, and secondary water barrier. When your inspector marks that all openings are protected with approved impact-rated products, your insurance company applies the corresponding credit to your policy. The combination of impact windows with a code-compliant roof can yield the largest savings. At Florida Impact Windows & Doors, we provide all the documentation your inspector will need, including the product approvals, Notice of Acceptance numbers, and installation permits. We also recommend trusted Wind Mitigation Inspectors throughout Miami-Dade, Broward, and Palm Beach counties who can perform the inspection promptly after your installation is complete. Many of our customers find that the insurance savings alone cover a meaningful portion of their monthly financing payment, making the upgrade essentially self-funding over time.

No, if you have properly rated and installed impact windows covering all openings in your home, you do not need hurricane shutters. Impact windows are approved as a standalone hurricane protection system under the Florida Building Code and the Miami-Dade High Velocity Hurricane Zone standards. They are tested to withstand both debris impact and sustained cyclical wind pressure, which means they provide continuous protection without any additional barrier. This is one of the primary advantages of impact windows over shutters: they are always in place and always ready. That said, some homeowners choose to keep or add shutters over their impact windows as a secondary layer of protection, particularly on oceanfront or bay-front properties that face the most extreme exposure. While this is not required by code, it can provide extra peace of mind and an additional barrier against debris. If you already have shutters and are adding impact windows, you are free to remove them, keep them in storage, or leave them in place. Your insurance Wind Mitigation Inspection will note the impact windows as your primary opening protection regardless. From a practical standpoint, eliminating shutters is a major quality-of-life improvement for South Florida homeowners. Anyone who has spent a sweltering afternoon putting up panels or accordion shutters before a storm knows how physically demanding and time-consuming it can be. With impact windows from Florida Impact Windows & Doors, there is nothing to install, nothing to store in your garage, and no need to rush home from vacation when a storm threatens. Your home is protected around the clock, every day of the year.

Cleaning and maintaining impact windows is straightforward and requires no special products or techniques. For routine cleaning, simply use a mild soap or a standard glass cleaner with a soft cloth or squeegee, just as you would with any window. Avoid abrasive cleaners, steel wool, or razor blades, as these can scratch the glass surface or damage the laminated interlayer's seal. In South Florida, where salt air, pollen, and hard water spots are common, we recommend cleaning your windows at least once a month to keep them looking their best. Beyond the glass, it is important to maintain the window tracks, hardware, and weatherstripping. Use a soft brush or vacuum to remove debris from the tracks every few months, and apply a silicone-based lubricant to the tracks and moving hardware twice a year. This prevents the rollers and operators from sticking, which is especially important in South Florida's humid climate where moisture and fine sand can accumulate quickly. Check the weatherstripping annually for signs of cracking or compression, and replace it if you notice gaps that could allow air or water infiltration. Florida Impact Windows & Doors recommends a simple annual inspection of your impact windows to ensure everything is performing optimally. Look for any visible cracks in the glass (rare, but worth checking after a severe storm), confirm that all locks and latches engage properly, and make sure the window seals tightly when closed. If you notice any issues, contact our service team. Most maintenance items are minor and inexpensive, and staying on top of them ensures your impact windows continue to deliver top performance for decades.

In most cases, cracked impact glass cannot be repaired and the affected glass unit will need to be replaced. Unlike a standard automotive windshield, which can sometimes be repaired with a resin injection for small chips, impact window glass is a laminated assembly that relies on the full integrity of its layers to provide hurricane protection. If the outer or inner pane is cracked, the structural performance of the laminated unit may be compromised, and replacement is the recommended course of action to ensure your home remains fully protected. The good news is that a cracked impact window does not need to be an emergency. Because of the laminated interlayer, even a cracked pane will remain in place and continue to provide a barrier against water intrusion and break-ins. The window will not shatter and fall out the way conventional glass would. However, you should not rely on a cracked impact window for hurricane protection, so it is important to schedule a replacement before storm season. In South Florida, that means having any damage addressed well before June 1, when hurricane season officially begins. At Florida Impact Windows & Doors, we offer glass replacement services for impact windows, even if we did not perform the original installation. Our team will identify the exact glass specification, order the replacement unit, and install it efficiently. If your windows are still under the manufacturer's warranty, the glass replacement may be covered at no cost to you. We recommend contacting us as soon as you notice any damage so we can assess the situation and get your home back to full protection as quickly as possible.

Impact windows typically come with two separate warranties: a manufacturer's product warranty and an installer's workmanship warranty. The manufacturer's warranty covers defects in the glass, frame, hardware, and other components. Depending on the product line, these warranties range from 10 years to a limited lifetime. Premium brands commonly installed in South Florida often include a limited lifetime warranty on the glass and frame for the original homeowner, with provisions for transferability to subsequent owners that vary by manufacturer. The workmanship warranty covers the quality of the installation itself, including proper sealing, anchoring, flashing, and finishing. At Florida Impact Windows & Doors, we provide a robust workmanship warranty because we stand behind the quality of our installation teams. If you experience any issues related to how your windows were installed, such as water infiltration due to improper sealing or operational problems caused by incorrect fitting, we will address it promptly at no cost. We use only factory-trained installers who follow the manufacturer's installation specifications to the letter, which is critical for maintaining the validity of both warranties. It is important to understand what can void a warranty. Common issues include improper cleaning methods that damage the glass coating, unauthorized modifications or repairs, and failure to perform basic maintenance. We provide every customer with a care and maintenance guide specific to their product so they know exactly how to keep their windows in warranty-compliant condition. If you ever have a warranty claim, Florida Impact Windows & Doors acts as your advocate with the manufacturer, handling the communication and coordinating any necessary service so you can focus on enjoying your home rather than navigating warranty bureaucracy.
