Fast, Reliable Window Installation Across South Miami
Window installation in South Miami means working inside Miami-Dade’s High-Velocity Hurricane Zone, and that changes everything about what gets ordered, how it’s anchored, and which permits the city requires. A typical impact window replacement in South Miami runs $900 to $1,800 per window installed, with whole-home packages ranging from $8,000 to $25,000 depending on opening count and frame condition. If you’re standing in a 1960s CBS ranch off Sunset Drive wondering whether those old jalousies are even legal anymore, call Winslow Windows & Doors at (863) 251-5864. We’ve been opening up South Miami walls long enough to know what’s behind them before the first cut.
Our crews serve South Miami directly, and Ed Winslow’s name is on the door, and on every job we do. We’re the Window Installation contractor who shows up in uniform, writes a line-item quote you can actually read, and pulls the permit that protects the work.
Why Winslow Windows & Doors Is South Miami’s Preferred Window Installation Company
We’re locally owned by Ed Winslow and we’ve been doing this since 2011. That’s fifteen years of pulling Miami-Dade permits, scheduling NOA-approved product, and standing behind the finished opening. South Miami homeowners deal with us directly, not a national chain’s ticketing system. When you call, a live person answers. Not a voicemail loop. Not a call center in another state. A real human who knows the difference between a buck frame and a direct-set CMU installation.
Our South Miami customers call for the same reason: they own a home built between 1950 and 1975, the windows are original, and the insurance renewal letter just landed with the word “non-renewal” in bold. That’s a problem we solve every week. We know the block patterns on SW 60th Street. We know how the salt air off Biscayne Bay eats aluminum frames faster three blocks east of US-1 than it does six blocks west. That’s local knowledge you can’t fake.
Our Window Installation Services in South Miami
Single & Double Hung Windows
Single and double hung windows are the go-to replacement for South Miami’s CBS ranch homes because they drop cleanly into existing rough openings with minimal stucco disturbance. A double hung from ECO Window Systems gives you top and bottom sashes that tilt in for cleaning, which matters when your windows face a busy street off Red Road and you’re not interested in scaling a ladder every spring. We size the design pressure to the specific opening, not the house average, because a north-facing window on Ludlam Road sees different wind loading than a west-facing one on SW 64th Street.

Horizontal Roller Windows
Horizontal roller windows make sense in South Miami’s postwar homes where the original openings are wider than they are tall, which is common in the 1950s floor plans around Dante Fascell Park. These units slide side to side and handle the HVHZ wind zone well when the frame is anchored into properly buck-framed openings. Expect to pay $850 to $1,500 per opening installed, depending on whether we’re cutting out a jalousie or a failed aluminum slider.

3-Panel Sliding (3-Lite Roller) Windows
The 3-panel slider is a South Miami classic, especially on homes where a single wide opening once held a bank of jalousies facing the backyard. We frame the rough opening tight, set the three lites on a continuous sill, and anchor the whole assembly to the CMU with approved fasteners spaced to the product’s NOA. A 3-lite slider in South Miami typically runs $1,800 to $3,200 installed, and we quote it by the opening, not by some national square-foot formula that ignores how CBS walls behave.

Casement Windows
Casement windows seal tighter than anything else in a wind-driven rain, which is exactly what South Miami gets when a summer squall pushes off the Bay. The crank-out sash compresses the weather stripping on all four sides, and because the panel is one solid piece of glass in a steel-reinforced frame, it’s the best-performing impact option for bedrooms and rear elevations. We set PGT casements with Miami-Dade NOAs into openings along SW 62nd Avenue regularly, and the difference in daytime heat gain is immediate.

Trusted Brands We Service in South Miami
We’re an authorized installer for ES Windows, ECO Window Systems, Mr-Glass, and Therma-Tru, which means we can order the right configuration with the right NOA without a middleman guessing at South Miami’s wind zone. If you already have a brand you like, we’ll work with it. If you’re starting fresh, we’ll recommend what holds up in this specific climate. And because we stock common parts locally, a warranty repair call doesn’t turn into a three-week wait for a truck from Tampa.
Common Window Installation Problems We See in South Miami Homes
- Jalousies mortared directly into CMU. On a 1960s CBS ranch off Sunset Drive, our crew cut out three jalousie windows mortared directly into the block without a single crack in the surrounding face, then buck-framed each opening for PGT impact-rated casements carrying the Miami-Dade NOA and large-missile rating. Most contractors unfamiliar with CBS work chip the block and leave you with a masonry repair bill before any window goes in.
- Rotted wood bucks behind the stucco. Salt-laden air from Biscayne Bay rots the aluminum frames and silicone seals in 1950s-era windows, causing slow leaks that rot the wood buck and framing behind the stucco. By the time you see the interior water stain, the framing repair is already part of the job.
- Out-of-square openings in pre-war bungalows. South Miami still has wood-frame bungalows along older streets north of Sunset, and their rough openings have shifted over 70 years. A window pulled off a shelf will not fit. We measure every opening on four corners and order to the narrowest dimension.
- Insurer non-renewal over non-compliant jalousies. Your jalousies might open and close fine, but they fail the Miami-Dade wind-borne debris standard, and your insurer can non-renew the policy specifically because of them. That’s a South Miami problem we fix with a documented replacement and an updated wind mitigation report.
What Window Installation Costs in South Miami
A full impact window replacement in South Miami lands between $900 and $1,800 per window installed for standard openings. Single-hung impact units fall at the lower end of that range. Large or custom openings, like a picture window facing the yard or a bay assembly, run $2,500 to $5,000. Whole-home packages for a typical three-bedroom CBS ranch start around $8,000 and can reach $25,000 or more when you’re replacing 12 to 20 openings with casements and sliders.
What moves the price in South Miami? Opening count first. Then wind zone, which is HVHZ everywhere in this city, so there’s no cheaping out on a lower-rated product. Floor height matters too, because a second-story window needs different anchoring and faster installation time. Frame material matters: vinyl is the budget path, aluminum is common in modern homes, and wood-clad only makes sense on the pre-war bungalows.

Here’s the South Miami pricing reality in one table:
| Scope | Price Range in South Miami |
|---|---|
| Single impact window (standard opening) | $900 – $1,800 |
| Large or custom opening | $2,500 – $5,000 |

Pricing for Window Installation in South Miami, FL
Most South Miami homeowners we quote are replacing jalousies with impact casements or double hungs, and the per-opening cost usually lands between $900 and $1,800 once you factor in the buck framing, the NOA-compliant product, and the permit. A straight swap where the rough opening is square and the framing is sound sits at the low end. A 1962 CBS ranch with three jalousies cut into block can push the per-opening number higher because of the extra framing and masonry care. We give free estimates with no trip charge inside our home county, and seniors and veterans always get 10% off.
Florida Pays You Back
South Miami homeowners can stack several programs that cut the real cost of impact windows. The My Safe Florida Home program provides matching grants up to $10,000 for qualifying wind-mitigation upgrades, and a new impact window package is exactly the kind of improvement they fund. Florida also exempts impact-resistant windows and doors from sales tax, which saves you 6 to 7 percent at checkout. On the federal side, the 25C energy credit covers 30 percent of the product cost, up to $600 per year, on qualifying units.
Then there’s the insurance angle. After a wind mitigation inspection, which runs around $75 to $150 in South Miami, most homeowners see the windstorm portion of their premium drop. The average credit is around 25 percent on that windstorm line, and we leave you with the documentation your carrier needs. We don’t guarantee what your insurer will do. We do guarantee the windows will meet the code that triggers the credit.
How an Impact Window Job Unfolds in a 1950s South Miami CBS Home
The moment we open the wall, the job changes. That’s not a scare tactic, it’s how older South Miami homes actually work. Your 1957 ranch on SW 61st Avenue may look fine from the street, but behind the stucco there’s a wood buck that’s been soaking up salt-laced humidity for sixty years. There may be outdated wiring stapled to the framing where the new window anchor needs to go. The rough opening may be wider on one side than the other. A permit triggers code upgrades, and if the inspector sees non-compliant framing, it has to be fixed before we close the wall.
Here’s how we handle it: we inspect first, we write real allowances into the contract, and any surprise gets priced and approved in writing before we touch it. You will never get a call that says “we found something” followed by an unapproved change order. Ed’s name is on the business. The 36500-Day Done Right Promise means if it’s not done right, we make it right, period.

FAQs - Window Installation in South Miami
Because South Miami sits in the High-Velocity Hurricane Zone, and every window legally installed here must carry a Miami-Dade Notice of Acceptance tied to the specific design pressure and anchor spacing for this zone. A window with a Florida Product Approval but no Miami-Dade NOA cannot legally be installed. A handyman who installs non-compliant product is creating a code violation that can void your insurance and block a future sale. Call (863) 251-5864 and we’ll show you the NOA paperwork before we order anything.
Jalousies fail the Miami-Dade wind-borne debris standard, and once your insurer runs a property scan or pulls updated aerial imagery, they can non-renew your policy specifically because those windows are still in place, even if they function. The glass louver design cannot stop a wind-borne 2×4 at 50 feet per second, which is the literal test standard here. Replacing them with impact-rated windows and filing an updated wind mitigation report is the fix that keeps your policy alive.
We cut out the old window, expose the rough opening, and inspect the wood buck and surrounding framing. If the framing is sound, we anchor the new window per its NOA and close up. If we find rot, termite damage, or undersized framing, the inspector will require it be fixed before the wall is closed. That’s why we inspect first, write allowances into the contract, and get written approval before any additional work. The permit is what keeps the work legal, and the inspection is what protects you.
Impact windows in South Miami use low-E coatings and double or triple glazing that block a huge share of the solar heat that currently pours through your single-pane jalousies. South Miami’s cooling season runs effectively from March through November, so a home with 10 or 12 replacement windows sees real savings on FPL bills. The bigger financial lever is the insurance premium credit after your wind mitigation inspection, which most South Miami homeowners notice immediately.
Not legally, unless that specific window also carries a Miami-Dade NOA for the design pressure your opening requires. Most big-box inventory windows do not carry the NOA, and South Miami is the only city in Florida where a window cannot legally be installed without it. Even a unit sold in Miami proper may not be legal here, because South Miami’s HVHZ requirements are stricter than state minimums. Call (863) 251-5864 for an exact quote on NOA-compliant product; estimates are free.
