AfterTrusted Impact Windows for South Miami Homeowners
Impact window installation in South Miami typically runs $95-$145 per square foot installed, with most single-family homes landing between $14,000 and $28,000 total depending on opening count, glass package, and frame material. We install and replace PGT, CGI, CWS, and ES Windows impact-rated systems, and we’ve been doing it in South Miami since 2011 - see our Impact Windows Maintenance Checklist for South Miami Homeowners for upkeep tips, with every job backed by Ed Winslow’s Done Right Promise. Call (850) 930-1813 and a live person answers, any hour of any day.
South Miami sits in a High Velocity Hurricane Zone, which means the impact windows we install here aren’t a luxury upgrade. They’re the difference between your living room staying dry through a Category 4 and your roof lifting because wind pressure found its way inside. Ed Winslow has spent 15 years securing homes across Miami-Dade, from Impact Windows - Miami to South Miami, and his name is on the door, and on every job we do. If you’re pricing impact windows in South Miami, you’ll want numbers, a clear scope, and a contractor who doesn’t vanish after the deposit clears. That’s how we work.
Key Takeaways
- South Miami is in a HVHZ wind zone. Impact windows here must meet Miami-Dade County product approval standards, and we only install systems that carry current NOAs.
- You don’t always need full replacement. We assess existing frames for integrity, and where frames are sound, we can often install impact glass into the same openings at a lower cost.
- Every installation includes a written line-item quote before any work starts. The number you approve is the number you pay, full stop.
- Ed Winslow answers the phone. Not a call center, not a ticket number. You get the owner’s word and the Done Right Promise on paper.
What Our Impact Windows Service Includes
Impact Window Replacement
When existing frames are rotted, racked, or older single-pane aluminum from the 1970s and 80s, replacement is the honest answer. We remove the old window down to the rough opening, inspect the buck and lintel for hidden water damage, and set the new impact unit with the proper anchoring schedule Miami-Dade’s product approval requires. A replacement job in South Miami means we’re pulling permits, scheduling inspections, and documenting every layer so the final product approval is on record with the county. You get a window that’s code-compliant today and still code-compliant when you sell the house in 15 years.
Impact Window Installation for New Construction and Additions
If you’re building an addition or a new home in South Miami, the impact windows have to be on the approved product drawing before the first inspection. We work directly with your architect or GC to verify sizes, design pressures, and anchoring details so the windows you spec actually pass the plan review the first time. Ed’s team has installed impact packages in new builds from Pinecrest to Kendall, and we know which products get through the county faster without sacrificing glass quality. We coordinate delivery around your framing schedule, because a window sitting on-site for three weeks is a window that gets damaged, and that’s your money.
Impact Glass Retrofit Into Existing Frames
South Miami has thousands of homes with substantial aluminum or wood frames that are still structurally sound. In those cases, we can often remove the old non-impact glass and install impact-rated laminated glazing into the existing opening. This cuts the cost meaningfully versus full replacement, keeps your interior trim and stucco untouched, and still gets you a product approval because the assembly is tested as a retrofit system. We’ll be straight with you: not every frame qualifies. We measure frame depth, check for corrosion, and verify the existing anchoring before we’ll quote a retrofit, because a retrofit into a weak frame is a window that fails when you need it.
Impact Sliding Glass Doors and French Doors
Glass doors are where South Miami homes lose the fight first. A 6-foot or 8-foot sliding glass panel takes enormous wind load, and if it flexes or bows, the whole building envelope is compromised. We install impact-rated sliders and French doors with reinforced frames, multi-point locking hardware, and the heavy laminated glass that keeps wind and debris outside. We also check the door’s threshold sealing and drainage, because a door that’s impact-rated but leaks at the sill is a call you’ll be making after the first heavy summer storm, and we’d rather fix it before the storm ever comes.
Impact Garage Doors
Most South Miami homeowners forget the garage door until they see it bowing inward during a wind event. A non-impact garage door that fails under wind pressure can blow out and pressurize the entire house, and that’s when you lose the roof structure. We install impact-rated garage doors that are tested for both positive and negative wind pressure, with reinforced track systems and bracing that keep the door where it belongs. It’s not a window, but it’s part of the same envelope, and a big gap in your protection is a big problem.
Custom and Geometric Impact Windows
South Miami has its share of mid-century homes with eyebrow windows, round windows, and odd angles that big-box installers won’t touch. We do. Custom impact shapes require templating, special structural glazing, and a fabricator who understands design pressure on non-rectangular lites. We’ve fabricated and installed impact-rated circles, arches, and trapezoids for homes in Coral Gables Impact Windows and South Miami proper, and each one carries its own product approval. If you’ve been told your unusual window “can’t be done in impact,” call us. We hear that a lot, and we prove it wrong a lot.

Brands We Service for Impact Windows
We’re an authorized installer for PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru. That means we don’t just order these products, we’ve completed factory training on their installation requirements, and we stock the manufacturers’ specified fasteners, sealants, and flashing materials for each system.
CWS builds some of the heaviest aluminum impact windows on the market, and their multi-chamber frames are a favorite for South Miami homes that want a commercial-grade look without the commercial price tag. We’ve installed CWS from Doral to our Impact Windows in Hialeah to Palmetto Bay, and our crews know the exact anchoring pattern their product approval calls for. ES Windows is the choice when you want architectural aluminum with a European profile, huge glass area, and impact ratings that still meet Miami-Dade code. Their systems require very specific shimming and leveling, and it’s work we do every week. ECO Window Systems gives South Miami homeowners a strong mid-range option with good energy numbers and solid availability, and we’ve put them in everything from 1950s ranchers to new builds in Three Lakes. Whether you’ve got a brand preference or you want us to recommend the right glass package for your exposure, we can help.
Signs You Need Impact Windows Right Now
- Your home in South Miami still has original single-pane windows. Single-pane glass shatters on impact and allows wind pressure to enter the home, which is how roofs get lifted off. If a window has a metal tag that says anything other than “impact rated” or “laminated,” it’s the weakest point on your house.
- You can hear everything happening on the street. Impact laminated glass cuts exterior noise dramatically because of the plastic interlayer between the two panes. If a garbage truck sounds like it’s in your kitchen, it’s not just an inconvenience, it’s a security risk, and it’s costing you sleep.
- Your AC bill is climbing every summer. Non-impact windows in South Miami leak conditioned air all day, every day, for eight months of the year. Impact glass with Low-E coating reflects solar heat gain, and homeowners routinely see meaningful energy savings after a full replacement.
- Your window frames show white oxidation or rot. Aluminum frames in this climate corrode from salt and humidity exposure, and wood frames rot from condensation at the sill. If the frame is compromised, the glass can fall out under wind load, whether it’s impact-rated or not.
- You’re planning to sell or refinance. Insurance carriers in Miami-Dade are requiring windstorm mitigation credits, and buyers are asking for documentation. Homes with impact windows and proper opening protection sell faster, and the insurance savings often pay for the windows within a few years.
Our Impact Windows Process - Step by Step
Step 1: You Call, Ed’s Team Answers
Call (850) 930-1813. A live person picks up, 24/7. We’ll ask about your home’s age, current window types, any water damage you’ve noticed, and what’s driving the project. You’ll get a window for a free estimate, not a callback “sometime next week.” If you have a written estimate from another company, we’ll give you a free second opinion on it.
Step 2: The Site Visit and Window-by-Window Assessment
Ed or a senior tech walks the house with you, opening by opening. We measure each window, check frame condition, identify structural issues like sagging lintels or rotted sills, and test operation. We’re not there to sell you 19 windows if 12 of them can be retrofitted safely at half the cost. You’ll get an honest read on what’s required, what’s optional, and what can wait.
Step 3: Written Line-Item Estimate
Within a few days, you’ll have a written estimate that breaks out each window by size, glass package, frame type, and installation labor. No vague “allowances.” No “prices subject to change.” The number on that paper is the number that goes on the invoice. We’ll also walk you through financing options and any insurance credits you may qualify for.
Step 4: Permits, Ordering, and Installation
We pull the Miami-Dade permit under our license, order your windows with the exact specifications quoted, and schedule your install. Our crews are background-checked, uniformed, and supervised by a lead installer who’s been with Winslow for years. Most whole-home replacements in South Miami take 3 to 5 days on-site, depending on opening count and structural repairs uncovered along the way. We protect your floors, work clean, and you’ll know exactly who’s in your house before the truck ever pulls up.
Step 5: Inspection and the Follow-Through
After the install, we schedule the county inspection, and we’re on-site when the inspector arrives so nothing gets kicked back. Once you pass, we walk the job with you, make sure every window operates the way it should, and hand you all the documentation: product approvals, warranty registration, and permit sign-off. And if anything isn’t done right, you call Ed, and he makes it right. That’s the Done Right Promise, and it’s on paper with every job.
How Much Does Impact Windows Cost in South Miami?
Expect $95 to $145 per square foot installed for a full replacement, with the final number moving based on the size of the job, the brand, the frame finish, and whether we’re dealing with any hidden structural issues. A mid-size single-family home in South Miami with 10 to 14 openings typically comes in between $14,000 and $28,000. A retrofit into existing frames runs lower, usually $60 to $85 per square foot, but only when the frames genuinely qualify.
What moves the price: glass package (clear laminated vs. Low-E tinted), frame type (vinyl is more affordable; architectural aluminum like ES Windows costs more), opening size and shape (custom arches add cost), second-story work, and any rotten wood or corroded framing we uncover during removal. The way to avoid overpaying is to get an itemized quote that names every window and every charge, and to verify the contractor is pulling permits. A permit means an inspection, and an inspection means someone independent is checking the work.
Our free estimate includes the full written scope, permit fees, and a fixed price that doesn’t change unless you change the scope. We also keep our permanent standing offers in place: $40 off any repair over $200, a 10% discount for seniors and veterans, and no trip charge inside our home county. If you’re comparing numbers, call (850) 930-1813 and we’ll walk through them with you honestly.

Frequently Asked Questions - Impact Windows in South Miami
An impact window is a window system built with laminated glass and a reinforced frame, designed to withstand windborne debris and extreme wind pressure without breaking or separating from the structure. South Miami requires impact windows to carry a Miami-Dade County product approval, meaning the specific product has been tested and certified for use in the High Velocity Hurricane Zone. The laminated glass has a plastic interlayer that holds the glass together even if the outer pane is struck, which keeps wind and water outside where they belong. Call (850) 930-1813 to find out if your current windows carry that approval. We can check while we’re there.
Most whole-home replacements in South Miami are done in 3 to 5 working days on-site, with larger or custom jobs extending from there. The permitting process before installation usually runs 1 to 3 weeks depending on county review times. A single window replacement can often be completed in under a day, and we’ll give you a clear schedule in your written estimate before any work begins.
Plan for $95 to $145 per square foot installed for full replacement, with most South Miami homes falling between $14,000 and $28,000 depending on opening count and product selection. Retrofit into existing sound frames typically runs $60 to $85 per square foot. The final number depends on glass package, frame material, custom shapes, and any structural repairs, but you’ll get a fixed written price before we order anything.
