What Our Impact Windows Service Includes

Impact Window Installation

Impact window installation means replacing your existing single-pane or builder-grade windows with laminated, impact-rated units that meet Miami-Dade County’s strict High Velocity Hurricane Zone (HVHZ) building code. You need this when your windows are older than 15 years, when you can feel drafts or hear street noise through the glass, or when you are buying or selling a home and the inspection flags outdated fenestration. Winslow Windows & Doors handles every phase: we measure each opening individually, order the right PGT or CGI unit for that specific wind-load zone, pull the permit, and install the windows with proper flashing and anchoring so they do not just survive a storm but also pass a post-installation inspection the first time.

Impact Window Replacement

Impact window replacement swaps out failed or non-compliant windows without necessarily redoing trim, drywall, or interior finishes, which keeps the project faster and less invasive than a full-frame install. You might need replacement if your existing impact glass has a hairline crack, if the laminate layer is delaminating and turning milky, or if a previous installer used the wrong anchors and the frame now flexes under pressure. Our crew will inspect every existing unit, identify which windows can be saved and which need full replacement, and never sell you a whole-house job when three sashes will do. Every replacement we do in Miami includes new weep-hole covers, re-sealed flashing, and a written workmanship warranty under our 36500-Day Done Right Promise.

Impact-Resistant Glass and Laminated Glass Upgrades

Some Miami homeowners already have aluminum or vinyl frames in good shape but want to upgrade from standard tempered glass to impact-rated laminated glass without replacing the entire window. This is common in Coral Gables and Palmetto Bay, where homes built in the early 2000s often have sturdy frames but outdated glass packages. Winslow Windows & Doors can retrofit compatible frames with ViewLux or CWS laminated insulated glass units that carry a Miami-Dade NOA (Notice of Acceptance), which means they are approved for wind-borne debris zones. We will tell you honestly whether a glass-only swap is code-compliant for your structure or whether the frame needs to go with it; we will not bend the rules to make a sale.

Impact Sliding Glass Doors and Patio Doors

Sliding glass doors and patio doors are the single largest glass opening in most South Florida homes, and an impact-rated panel here is often the most expensive and most important line item in the project. In Cutler Bay and Kendall, we regularly replace track systems and panels on older homes where the builder installed non-impact sliders that now leak during summer storms and rattle in heavy wind. Winslow installs impact-rated sliding glass doors with stainless steel rollers, interlocking stiles, and multi-point locking hardware, and we pre-hang every panel to confirm the reveal is even before the crew leaves. If your current slider is hard to open or you see daylight around the edges, that is a sign the entire frame has shifted and an impact-rated replacement is overdue.

Impact Window Repair and Seal Failure

Impact windows do fail, typically not the laminated glass itself but the seals, the balance springs, the roller assemblies, or the mounting hardware that holds the frame to the block or wood framing. You need this service when you see condensation trapped between the panes, when the window drops or slams when you open it, or when water intrudes along the top of the frame during a heavy Miami downpour. Our technicians carry OEM parts for PGT, CGI, CWS, ES Windows, and ViewLux units, and we re-bed and re-flash every frame we touch rather than caulking over a rotted opening. A good rule of thumb: any impact window that fails a water-spray test needs repair before the next hurricane season, not after.

Energy-Efficient Impact Window Packages

Miami homeowners pay some of the highest electricity rates in the Southeast, and replacing old clear glass with low-E, argon-filled impact windows typically cuts the cooling load on the west and south elevations by 30% or more. You need an energy package when your AC runs constantly in July, when furniture near the windows has faded, or when certain rooms are 8 to 10 degrees hotter than the rest of the house. Winslow specifies low-E coatings tuned for a cooling-dominant climate, meaning the glass blocks more solar heat gain while still allowing natural light, and we will show you the SHGC and U-factor on every quote. The energy savings are not speculation; they are math we run using your orientation, overhang depth, and window-to-wall ratio before we order a single panel.

Custom and Geometric Impact Windows

Arch-top, radius, circle-top, oval, and other geometric window shapes are common in Miami’s 1920s Mediterranean Revival homes and 1950s MiMo architecture, and off-the-shelf impact units simply do not fit those openings. You need a custom solution when you have a curved-top window, an angled transom, or an unusual mullion pattern that a box-store template will not match. Winslow Windows & Doors works with ES Windows and ECO Window Systems to produce fully custom laminated units in non-rectangular shapes that still carry Miami-Dade approval, so you do not have to board up an architectural window or replace it with an ugly rectangle. We also template every custom opening on-site to account for 80 years of settling, stucco buildup, and slightly out-of-square jambs.

Brands We Service for Impact Windows

Winslow Windows & Doors is an authorized installer for PGT, and we have installed hundreds of PGT WinGuard and PGT 5500 series units across Miami, Hialeah, and Miami Beach since 2011. We know how PGT’s laminated glass and heavy-gauge aluminum or vinyl frames behave in a real wind-load test, and we stock their factory hardware, not aftermarket substitutes, so a warranty claim never gets rejected because of generic parts. PGT is the most common impact window brand in South Florida, and when a PGT window fails, it is usually the original installation that caused it; we see that pattern constantly when we do free second opinions on other contractors’ work.

We also service and install CGI (including the Sentinel and Estate lines) and CWS impact windows, both of which are engineered specifically for the HVHZ market and popular in Doral, Aventura, and North Miami. CGI’s aluminum frames are built to take a direct hit from code-mandated large-missile testing, and our installers have completed the brand’s factory training for proper anchoring and flashing. CWS offers some of the widest available sightlines on a code-approved aluminum window, which matters to homeowners in older neighborhoods who want hurricane protection without shrinking their view. Whether you have ViewLux, ES Windows, ECO Window Systems, Therma-Tru, Mr-Glass, or any other make in your home today, we can service it, and if a unit is beyond repair, we will recommend the right replacement from a brand we actually stand behind, not whatever we happen to have in the warehouse.

Signs You Need Impact Windows Right Now

• Your windows are original to a home built before 2001. Miami-Dade County adopted the Florida Building Code with HVHZ impact requirements after Hurricane Andrew in 1992, but enforcement tightened significantly in the early 2000s. If your windows predate the modern code, they almost certainly lack laminated glass and proper anchoring, which means they are a structural weak point in a real storm. In Kendall and Homestead, we regularly replace windows on 1970s and 1980s homes that still have single-pane annealed glass with aluminum tracks, and the difference in water intrusion resistance is immediate.
• You can feel air movement or see daylight around the window frame. A properly installed impact window seals against both wind and water with compression gaskets and structural anchoring; if air passes through, water will too. This is not a comfort issue, it is a warning that the frame has pulled away from the block or that the original installers skipped the pan flashing. We see this constantly in Coral Gables and Palmetto Bay on windows installed by out-of-town crews who did not account for Miami’s relentless humidity and salt exposure.
• Water stains appear on the drywall or window sill after ordinary rain. If a routine afternoon storm leaves brown streaks or swollen paint under a window, the opening is already leaking, and the next tropical system will drive far more water into the wall cavity. By the time you see the stain on the interior, the sheathing or framing behind the stucco may already be rotting, and mold follows quickly in Miami’s climate. The fix is not recaulking; it is removing the old window, repairing the opening, and installing a properly flashed impact unit.
• Your insurance carrier has demanded impact protection or a wind mitigation credit. Many Florida insurers now require impact-rated windows or shutters as a condition of renewal, especially in coastal zip codes in Miami Beach, Aventura, and Cutler Bay. If you have received a letter from your carrier or your agent has told you a wind mitigation inspection would lower your premium, installing Miami-Dade approved impact windows is the most durable way to satisfy the requirement. We provide the NOA documentation your inspector and insurer need, and we do it without making you chase paperwork.
• You are planning to sell within the next five years. Buyers in Miami now ask for impact windows by name, and a home without them is often eliminated in the first walk-through or priced below comparable listings that are impact-rated. Even if you are not experiencing leaks or drafts, replacing aging windows before you list means you can advertise “full impact protection” in the listing rather than negotiating a credit after the inspection. A pre-listing assessment from Winslow gives you a clear budget number so you are making an informed decision, not guessing under contract deadlines.

Our Impact Windows Process - Step by Step

Here is exactly how a typical impact window project in Miami goes when you work with Winslow Windows & Doors. No mystery, no disappearing crews, no “we’ll get back to you.” A real person is on the phone 24/7 at (863) 946-5039.

1. 1
   Phone consultation and rough pricing. You speak with a live, local person, not an automated system or a national sales center. We ask about your home’s age, construction type (CBS block, frame, or a mix), window count, and whether you have any existing damage or leaks. Based on that conversation, we give you a realistic price range so you know before we even step foot in the house whether this is a ol5,000 job or a $40,000 job. This step costs you nothing and takes about 20 minutes.
2. 2
   On-site measurement and opening inspection. We send a background-checked, uniformed Winslow technician to your Miami home to measure every window and door opening individually, because Miami homes settle, stucco builds up, and two windows in the same room are rarely identical. The technician checks the condition of the existing frames, the lintel and header above each opening, the interior casing, and the condition of the surrounding stucco or siding. We also probe for hidden rot or termite damage in the rough opening, because installing an impact window over a compromised frame is a waste of money and a future failure.
3. 3
   Written line-item quote and product selection. Within a few days of the site visit, you receive a written quote that breaks out every window by size, brand, glass package, and labor cost, so you can see exactly where your money goes. We will show you options from PGT, CGI, CWS, ES Windows, ViewLux, and ECO Window Systems with different frame colors, glass tints, and energy-performance ratings. The quote includes permit fees, and we will not surprise you with a change order later for something we could have seen during the walk-through. If you have a competing quote, we will review it line by line for free.
4. 4
   Permit acquisition and product ordering. Winslow Windows & Doors pulls the permit from Miami-Dade County or the local municipality (Coral Gables, Doral, Miami Beach, and others all have their own building departments with their own requirements). We submit the product approvals, NOA numbers, and wind-load calculations as part of the permit package, and we handle any plan review comments or corrections. Once the permit is approved, we order the windows with the exact dimensions and glass packages from the quote; nothing gets substituted without your written approval.
5. 5
   Installation, inspection, and walk-through. The crew arrives on the scheduled day, removes the old windows, repairs any damaged openings, installs the new impact units with the correct anchors and flashing per manufacturer and code, and seals the exterior to match your home’s existing finish. After installation, the county or city inspector performs the required inspection, and we stay on site until it passes. Then Ed or a senior project lead walks every window with you, shows you how the locks and hardware work, and leaves you with all warranty documentation before the crew packs up. You have our direct phone number, and we answer it.
