Fast, Reliable Window Installation Across Olympia Heights
Window installation in Olympia Heights means working under Miami-Dade County’s High Velocity Hurricane Zone rules, where every opening you replace has to carry a Miami-Dade Notice of Acceptance number before an inspector will sign off. We know that because we pull permits here weekly, and we’ve seen what happens when a crew shows up with product that passes everywhere else in Florida and still fails rough inspection on SW 40th Street. Winslow Windows & Doors has been installing impact-rated windows across Olympia Heights since 2011, with PGT, CGI, and ECO Window Systems units cut to your exact rough openings. Call (850) 930-1813 and a live person answers, day or night.
Why Winslow Windows & Doors Is Olympia Heights’s Preferred Window Installation Company
Ed Winslow put his name on this company in 2011, and that changes how every job gets run. No ticket numbers. No call center between you and the person who actually shows up. When an Olympia Heights homeowner calls about a failed seal on a 1960s aluminum slider, they talk to someone who has opened those exact walls and knows what’s hiding behind the jalousie frame.
Our Olympia Heights customers regularly tell us the same things: the background-checked, uniformed crew arrived when we said they would, the permit closed without a correction notice, and nobody invented a surprise once the stucco came off. That last part matters more here than almost anywhere else in Florida, because Olympia Heights homes are 1950s-1970s CBS construction. Opening a wall for Window Installation on those homes can reveal rotted wood bucks, rusted steel lintels, or undersized rough openings that were never flashed correctly. We write allowances into the contract before we cut, and any change order gets priced and approved in writing before we touch it. That’s how we’ve kept a strong reputation across Olympia Heights for over a decade, and why we stand behind every install with the Done Right Promise.
Our Window Installation Services in Olympia Heights
Most Olympia Heights homes are single-story CBS ranches built between the late 1950s and 1970s, and the original windows on those houses follow a pattern. Jalousie louvered glass on the back and side walls, single-pane aluminum sliders in the living areas, and the occasional steel casement that has rusted through at the sill. Here are the replacements we install most often in this neighborhood.
Single & Double Hung Windows
Single and double hung impact windows are the standard replacement for original jalousie openings in Olympia Heights, because they give you the same vertical ventilation the old louvers provided, but with a Miami-Dade NOA rating and a tight seal against humidity above 70%. The vertical sash configuration also matches the proportions of most 1950s CBS window openings without requiring major header work.

Horizontal Roller Windows
Horizontal roller windows replace the original aluminum sliders that dominate Olympia Heights living rooms and Florida rooms. Those old sliders almost always have failed seals by now, which you’ll see as condensation fogged permanently between the panes. We install impact-rated horizontal rollers with marine-grade stainless tracks that hold up to the salt air and near-daily thunderstorms that chew through hardware faster here than almost anywhere in the continental U.S.

3-Panel Sliding (3-Lite Roller) Windows
Larger openings, like a living room picture wall facing the backyard, often call for a 3-panel slider. In Olympia Heights, those wide openings were usually framed with a fixed center lite and two narrow side sliders back in the 1960s. A modern 3-lite roller gives you the same wide view with impact glass and a design pressure rating matched to the specific wind zone for your block, not a generic number pulled off a catalog.

Casement Windows
Casement windows are the right call when you want maximum ventilation from a narrow opening, and they seal tighter than a slider under wind pressure because the sash presses against the frame on all four sides. We see casements used most often in Olympia Heights kitchens and bathrooms where the original openings are smaller and a crank-out sash is simply more practical than a sliding track.

Trusted Brands We Service in Olympia Heights
We’re an authorized installer for eight brands, but for Olympia Heights homes, ECO Window Systems, Mr-Glass, and Therma-Tru come up most often. ECO Window Systems and Mr-Glass both manufacture HVHZ-rated impact units with Miami-Dade NOA listings across multiple configurations, which means the permit package goes through without a second look. Therma-Tru handles the entry doors we often replace alongside windows when a 1960s hollow-core door has warped in the humidity. Because we’re local and schedule Olympia Heights jobs every week, we can order the exact product your opening needs instead of pushing whatever’s sitting in a warehouse.
Common Window Installation Problems We See in Olympia Heights Homes
- Jalousie windows that can’t be retrofitted. The louvered glass and crank hardware on original Olympia Heights jalousies carry no meaningful hurricane resistance, and you can’t just swap the glass. The entire frame has to come out, and the rough opening usually needs reframing for a proper impact unit.
- Failed seals on aluminum sliders. Twenty years of UV exposure and humidity above 70% breaks down the seal on non-impact insulated glass, leaving permanent fog between the panes. It’s not a cosmetic issue; it means the insulating gas is gone and the unit is no longer doing its thermal job.
- Rotted wood bucks hidden behind old frames. On 1950s and 1960s CBS construction, windows were often set in wood bucks anchored to the block. After 60 years of Miami humidity and the occasional leak, those bucks can be rotten. If the contractor doesn’t find it until tear-out, the job stalls and the invoice moves. We inspect and write the repair into the allowance before cutting.
- Non-compliant product from out-of-market contractors. A Florida Product Approval sticker means nothing to a Miami-Dade inspector if there’s no NOA number. Out-of-town crews show up with product that passes in Tampa or Orlando and still fails rough inspection in Olympia Heights. Then the homeowner is stuck with a pile of windows they can’t legally install.
Pricing for Window Installation in Olympia Heights, FL
For a standard impact window installation in Olympia Heights, expect to pay $900 to $1,800 per opening for a single-hung unit installed, and $800 to $1,500 per window for most standard impact windows with standard sizes. Larger openings, like a 3-panel slider or a wide picture window, run $2,500 to $5,000 installed. A whole-home replacement on a typical three-bedroom CBS ranch in Olympia Heights typically lands between $8,000 and $25,000 depending on window count, opening sizes, and how much reframing the original jalousie openings require. What moves the price here specifically is your wind zone, floor height, and the condition of the rough opening once we pull the old frame. We provide a free in-home measure and a written, line-item quote before any work starts, and the price on that quote is the price you pay unless you approve a change order in writing. Call (850) 930-1813 to schedule yours.
What Window Installation Costs in Olympia Heights
Let’s break down what you’re actually paying for in Olympia Heights. The unit itself is one piece, and impact-rated glass with a Miami-Dade NOA listing costs more than a standard Florida Product Approval window, because the engineering and testing are stricter. The installation labor is another piece, and on a CBS wall, that includes pulling the old frame, repairing or replacing the wood buck, flashing the opening correctly, and re-stuccoing the exterior. On a 1963 ranch off SW 40th Street, for example, our crew opened the wall for a jalousie-to-impact window swap and found water-rotted framing around the jamb, plus a 1970s aluminum slider with a failed seal. We wrote a change order for PT sill repair and flange waterproofing in the contract before cutting, priced and approved in writing, then installed PGT impact-rated double-hung units with NOA labels. Inspection closed the same week. That’s the difference between a quote that holds and one that jumps mid-job.
Window count is the biggest driver on whole-home jobs. A small 1950s ranch with eight openings will land at the lower end of the $8,000 to $25,000 range. Add a large picture wall, a garden window, or custom geometric glass, and you move toward the top. Frame material matters too: standard aluminum impact frames cost less than thermally broken or vinyl hybrid frames. The free in-home measure gives us the exact opening sizes and design pressures, so your written quote reflects your actual house, not a regional average.
Florida Pays You Back
Florida has real incentive money available for impact window upgrades, and a lot of Olympia Heights homeowners don’t know the full stack. The My Safe Florida Home program offers matching grants up to $10,000 for qualifying wind-mitigation upgrades, and impact windows are one of the eligible improvements. Florida also exempts impact-resistant windows and doors from sales tax, which saves real money on an $8,000 to $25,000 job. On the federal side, the 25C energy credit covers 30% of the product cost on qualifying energy-efficient units, up to $600 per year. And once the windows are in and you pass a wind-mitigation inspection, which typically costs $75 to $150, many carriers reduce the windstorm portion of your premium by roughly 25% on average. We can point you to the right paperwork, but your insurance company and the program administrators set the final numbers. We don’t promise discounts we can’t guarantee.
One more comparison worth making: impact windows versus hurricane shutters. Shutters only protect you when you remember to hang them before a storm, and in Olympia Heights, where design wind speeds exceed 150 mph, the storm that matters won’t wait for you to drag steel panels out of the garage. Impact windows protect permanently. No panels, no tracks, no decision to make at 2 a.m. while the wind picks up.

FAQs - Window Installation in Olympia Heights
It can, and this is the single biggest reason a window quote in Olympia Heights moves after tear-out. On a 1950s or 1960s CBS home, opening a wall can expose outdated wiring, undersized framing, or failed waterproofing that the inspector will flag before the permit closes. We handle it by inspecting first, writing realistic allowances into the contract, and pricing any surprise in writing before we touch it. No mystery line items on the final invoice. Call (850) 930-1813 for a free in-home measure and a written quote that accounts for what’s actually behind your walls.
No. Original jalousie frames from the 1950s through 1970s are not rated for any impact glass, and no Miami-Dade NOA-listed unit is approved for retrofit into a louvered frame. The entire frame has to come out, and in most Olympia Heights homes, the rough opening needs reframing before a proper impact window goes in. That’s a feature, not a flaw. It means the new window is anchored, flashed, and sealed to current HVHZ standards instead of sitting in a 60-year-old wood buck.
No. Olympia Heights is unincorporated Miami-Dade County, and all permits run through the county Building Department, not a city hall. Miami-Dade inspectors require a Miami-Dade Notice of Acceptance number on every window and door. A Florida Product Approval sticker without a valid NOA will fail rough inspection. We’ve seen out-of-market contractors bring product that passed everywhere else in the state and still get rejected in Olympia Heights. Before you sign, ask for the NOA number and verify it against the Miami-Dade product control database.
Because the contractor didn’t inspect the rough opening before quoting. Olympia Heights homes from the 1950s through 1970s often have rotted wood bucks, rusted steel lintels, or failed stucco-to-frame waterproofing hidden behind the old window. If the original quote didn’t include an allowance for that repair, the invoice climbs and the job stalls. We price the inspection findings into the contract before we cut, and any change that comes up during tear-out gets a written change order with your approval before we proceed.
There is no City of Olympia Heights permit. Olympia Heights is unincorporated, so the permit comes from Miami-Dade County’s Building Department. We pull the permit, schedule the inspections, and make sure the rough and final inspections close clean. If the product doesn’t carry a Miami-Dade NOA, the permit won’t pass, period. That’s why we only install units with valid NOA numbers matched to the design pressure of your specific opening.
