Walk through most of the homes in Dupree Lakes and you'll find a mix of original 1990s-era aluminum-frame windows, a handful of upgrades from whenever the last owner got around to it, and the occasional newer install that was done right. Plantation's housing stock in this part of Broward County skews older, and windows are usually the first thing to show their age — foggy double panes, warped frames, sliders that stick in the humidity, and single-pane glass that turns a west-facing living room into a greenhouse by 4pm every afternoon from May through September.
Window replacement here isn't just a cosmetic upgrade. In Broward County, it's a code, comfort, and storm-protection decision all at once. This page is specifically about window replacement and installation — not a general exterior overview — because windows carry their own set of rules, ratings, and trade-offs that deserve a straight answer before you sign anything.
Dupree Lakes sits inland from the coast, but distance from the ocean doesn't exempt it from Broward County's High-Velocity Hurricane Zone (HVHZ) building code — one of the strictest window and door standards in the country. That code applies countywide, whether a home is on a canal in Plantation or a mile from the Everglades.
In practice, this means any replacement window installed in Dupree Lakes has to carry product approval for HVHZ use — meaning it's been tested for large missile impact and cyclic wind pressure, not just rated for a generic "hurricane zone" somewhere else in the state. A window that's perfectly legal to install in Central Florida or the Panhandle may not have the approvals needed here. We only install product lines with valid Florida Product Approval (or Miami-Dade NOA) numbers appropriate for HVHZ, and we pull the proper permit for the work — no shortcuts, because an uninspected or improperly approved window can come back to bite you at resale or on an insurance claim.
Some homeowners in Dupree Lakes still rely on hurricane shutters or plywood over older, non-impact windows. That approach can technically satisfy code, but it means someone has to physically install protection before every storm, and the windows underneath stay weak, drafty, and outdated the other 350 days a year. Impact-rated windows solve both problems at once: the protection is built into the glass and frame, permanently, with no scrambling before landfall.
Storm protection gets most of the attention, but in a Dupree Lakes household, the window's job on a random Tuesday in July matters just as much as its job during a named storm. South Florida's combination of intense sun angle, high humidity, and long cooling seasons puts real stress on glass and frames that homeowners in cooler climates never have to think about.
Low-emissivity (Low-E) coatings reflect infrared heat before it enters the home while still letting visible light through — this matters enormously on west- and south-facing elevations, which take the brunt of the Florida afternoon sun. Frame material matters too: vinyl and reinforced aluminum both perform well in HVHZ-approved impact assemblies, but they behave differently in heat and humidity over time, and that's worth discussing room by room rather than assuming one frame type fits every elevation of the house.
Every code-compliant window comes with a National Fenestration Rating Council (NFRC) label listing U-Factor and Solar Heat Gain Coefficient (SHGC). U-Factor measures how much heat transfers through the window overall — lower is better. SHGC measures how much solar heat gets through the glass — also lower is better for a Florida home fighting AC costs most of the year. These two numbers matter more in Dupree Lakes than in almost any other U.S. climate, because the cooling season here is nearly year-round rather than a few summer months.
| Window Style | Typical Use in Dupree Lakes Homes | Cost Factors to Expect |
|---|---|---|
| Impact Single-Hung | Standard bedroom and hallway windows | Most economical impact option; simple opening reduces labor |
| Impact Casement | Kitchens, bathrooms, tighter openings | Crank hardware and tighter seal add cost over single-hung |
| Impact Sliding Windows | Wide openings, patios, family rooms | Larger glass area and heavier sash increase material cost |
| Impact Picture/Fixed | Great rooms, stairwell walls, feature windows | No moving parts lowers hardware cost but glass size drives price |
| Impact Sliding Glass Doors | Lanai and pool-deck access | Highest per-opening cost due to size, track hardware, and door panels |
Replacing windows the right way is more involved than swapping glass in an existing frame — done properly, it's a full removal and reinstall with attention to the rough opening, flashing, and water management underneath the stucco or siding.
Impact window replacement requires a building permit in Plantation, and the completed work gets a final inspection before it's closed out. We handle the permit application and schedule the inspection as part of the job — this isn't optional paperwork, it's what protects you if you ever file an insurance claim or sell the house and a buyer's inspector asks for proof the windows are permitted and approved.
Old windows come out, the rough opening gets checked for level, square, and any wood rot or moisture damage hiding behind the old frame, then the new impact unit goes in with proper flashing, shimming, and sealant before interior and exterior trim gets finished out. Most single-family homes in Dupree Lakes can have a full-house window replacement completed in a matter of days rather than weeks, weather and permitting schedules allowing.
Because impact-rated windows are custom-manufactured to each opening's exact size, there's typically a lead time between measuring and installation. It's worth planning around that lead time if you're hoping to have new windows in place before peak hurricane season rather than during it.
Not every window problem means full replacement, but in a lot of Dupree Lakes homes, several of these show up together and point to a whole-house upgrade rather than a patch job.
Window replacement is one of those projects where the license and insurance paperwork actually matters, not just the finished look. Florida requires a licensed contractor for this work, and in an HVHZ county, the installer needs to understand product approval numbers, permitting, and inspection requirements — not just how to caulk a frame. Before hiring anyone, it's reasonable to ask for a Florida contractor license number, proof of liability insurance and workers' comp, and confirmation that they'll pull the permit themselves rather than asking you to do it.
Alpine Exteriors holds Florida license RB29003900. We pull permits, coordinate inspections, and only install product lines with valid HVHZ approval for Broward County — we won't put in a window that isn't legally approved for this zone, even if it would be cheaper.
Dupree Lakes is a lake-and-canal community, and a lot of homes back up to water with wide-open rear elevations that catch more wind and sun exposure than the street-facing side. Those rear sliders and picture windows are often the best candidates for impact upgrades first, since they're both the biggest energy-loss culprits and the most exposed during a storm. The neighborhood's mature tree canopy also means falling limb debris is a real consideration in wind events — another point in favor of impact glass over older single-pane assemblies that weren't built to handle debris impact at all.
Storm season in South Florida runs June through November, with the highest activity typically August through October. Homeowners who plan replacement projects in the spring generally have more scheduling flexibility than those trying to get work done in the weeks before a storm is already in the forecast.
Every home in Dupree Lakes has its own mix of sun exposure, opening sizes, and existing window condition, and the right combination of style, glass package, and frame material comes out of actually looking at the house — not a one-size-fits-all quote. If you'd like a straightforward, no-pressure look at what your windows need, fill out the form below and we'll set up a free estimate.
Broward County's High-Velocity Hurricane Zone code requires new and replacement windows to meet strict impact and wind-pressure standards regardless of how far the home sits from the coast. Dupree Lakes falls under that same countywide code, so replacement windows need valid Florida Product Approval or Miami-Dade NOA numbers, not just a generic hurricane rating.
Confirm the contractor holds an active Florida contractor license and carries liability insurance and workers' comp, and ask directly whether they'll pull the required building permit themselves. In an HVHZ county, also ask whether the specific windows they're proposing carry current product approval for this zone.
Shutters or panels protect a window from the outside but have to be installed before every storm and leave the underlying glass unchanged the rest of the year. Impact windows build the protection into the glass and frame permanently, so there's nothing to put up or take down and the window performs better day-to-day too.
U-factor measures how much heat passes through the whole window assembly, and SHGC measures how much solar heat the glass lets in — lower numbers on both are better for Florida's long cooling season. Two windows can look identical but perform very differently depending on these ratings, so it's worth asking for the NFRC label numbers on any quote.
Not under Broward's code — the High-Velocity Hurricane Zone designation applies countywide, so an inland home in Plantation faces the same impact and wind-pressure requirements as one on the beach. Distance from the water doesn't reduce the code requirement, though it can factor into overall wind exposure on a given elevation.
