AfterFast, Reliable Custom & Geometric Windows Across Three Lakes
Custom and geometric windows in Three Lakes, FL typically run $2,500 to $5,000 per opening for large or unusual shapes, with whole-home packages landing between $8,000 and $25,000 or more. Every opening we install here carries a Miami-Dade Notice of Acceptance, because Three Lakes sits inside the High Velocity Hurricane Zone and the permit counter won’t accept anything less. Call (727) 291-4678 for a free in-home measure and a written quote that won’t change on you later.
Ed Winslow’s name is on the door, and that means something in Three Lakes. We’ve spent over 15 years learning exactly which window materials survive this specific pocket of Miami-Dade: canal-adjacent humidity, salt air in the afternoons, and the historical hurricane corridor that put Andrew’s ground zero just south of here. The homes here tell the story. Post-1992 rebuilds with aging aluminum frames. Pre-Andrew homes with jalousie windows that no longer meet code. We know what works, what fails, and what the inspector expects.
Why Winslow Windows & Doors Is Three Lakes’s Preferred Custom & Geometric Windows Company
Three Lakes homeowners call us because we’ve pulled permits here and we know the drill. The Miami-Dade permit counter doesn’t care about a Florida Product Approval stamp on a custom arch or trapezoid window. The inspector wants a current Miami-Dade NOA number on the label, period. General contractors who work Broward or Collier County miss this constantly. We don’t. We pull the NOA before demolition starts, so your shaped-window replacement never sits half-open with a stop-work order taped to the frame.
Our crews serve Three Lakes directly, coordinated from our South Florida metro office. Every technician who shows up at your door is background-checked and in uniform, so you know exactly who’s walking up your driveway before they knock. Calls are answered by a live person around the clock, not a voicemail loop. That’s been true since 2011. Ed Winslow owns this business, publishes our address and license number, and stands behind every job with the Done Right Promise: if it’s not done right, we make it right.
Reviews from Three Lakes customers mention the same things: upfront pricing, no change orders after the quote, and a crew that shows up when they say they will. We earn those reviews one inspection at a time.
Our Custom & Geometric Windows Services in Three Lakes
Custom Impact Windows
Most Three Lakes homes were built or rebuilt after Hurricane Andrew, and those original impact assemblies are now 30-plus years old. Laminated glass interlayers delaminate. Frames pit. Weatherstripping that once sealed fine now leaks air and water. Our Custom & Geometric Windows team measures each opening, checks the existing rough framing, and orders impact windows built to the exact size, NOA rating, and design pressure your wall needs. No shims, no oversized filler panels, no shortcuts.
Geometric & Shaped Windows
Trapezoids, pentagons, circles, octagons. Three Lakes homes have plenty of them, and big-box retailers don’t stock a single one off the shelf. Every geometric shape we install starts with a digital template taken on-site, not a rough guess with a tape measure. That matters when the window sits over a canal view and the opening is thirteen inches out of square, which happens more often than you’d think in 1990s CBS construction.
Arched & Curved Windows
Arched windows are common over entryways and canal-facing great rooms in Three Lakes, and they’re the first place humidity attacks. The curved frame joints catch condensation, the aluminum pits at the corners, and within five to seven years you’re seeing fog between the panes. We replace those arches with radius windows built to match the original curve while upgrading the frame, glass, and hardware to current HVHZ standards. Custom radius casements from PGT are a frequent spec.
Oversized Openings
Large picture-window openings and wide sliding glass walls face real wind loads in Three Lakes. The design pressure requirements move with the opening size, so you can’t just drop in any impact-rated unit and call it done. We verify design pressures for the specific opening, orientation, and floor height, then order accordingly. For oversized openings, we install only units with verified NOA ratings matched to the structural engineering, never a guess.

Trusted Brands We Service in Three Lakes
We’re an authorized installer for PGT, CGI, CWS, and ES Windows, among our eight premium brands. For Three Lakes custom shapes, we frequently specify PGT and CGI because their custom radius and geometric lines hold NOA certifications for HVHZ configurations that smaller shops can’t supply. When we quote your job, we match the brand to the opening, the wind zone, and your budget, not to whatever’s sitting in the warehouse. Fabrication for custom geometric windows runs four to six weeks, and installation is as fast as a single day once your units arrive.
Common Custom & Geometric Windows Problems We See in Three Lakes Homes
- White crust at frame corners. That’s aluminum pitting from canal-adjacent humidity, and it’s not cosmetic. Once the pitting eats through the frame wall, water intrudes behind the jamb and your wind-mitigation inspection fails. Three Lakes humidity is persistently higher than coastal Kendall or Pinecrest, so we see this on 25-year-old windows that look fine from six feet away.
- Fogged insulated glass in arches and trapezoids. Salt air breaks down the silicone seals around geometric glass shapes, and the insulating gas escapes. You’ll see condensation inside the panes, usually within five to seven years of install. That’s a seal failure, not weather, and it means the unit needs replacement, not repair.
- Failed permit inspections on replacement windows. A homeowner hires a Broward contractor who orders a custom geometric window with Florida Product Approval only. The Miami-Dade inspector rejects it at the permit counter. Now the old window’s out, the new one’s not installable, and the homeowner pays for a full reorder. We see this regularly and it’s entirely preventable.
- Jalousie and single-pane aluminum windows in pre-Andrew homes. These can’t be repaired into compliance. Current permit requirements demand full system replacement with NOA-rated impact assemblies. We help Three Lakes homeowners budget for that reality with written line-item quotes so there’s no surprise when the scope comes back.

What Custom & Geometric Windows Costs in Three Lakes
Impact windows in Three Lakes generally run $800 to $1,500 per window installed, with impact single-hung units from $900 to $1,800. Large or custom openings run $2,500 to $5,000, and whole-home packages start around $8,000 and can exceed $25,000 for extensive geometric work. Three Lakes pricing is shaped by HVHZ requirements that add real materials cost: thicker laminated glass, heavier frames, stainless hardware, and the engineering time to verify design pressures on every opening. We recommend an in-home measure; it’s the only way to price a custom shape accurately. The estimate is free and the quote is written, so nothing changes on you mid-job.
Florida Pays You Back
Three Lakes homeowners have access to several programs that offset the cost of impact-rated window replacement. My Safe Florida Home offers matching grants up to $10,000 for qualifying wind-mitigation upgrades. Florida exempts impact-resistant windows and doors from sales tax. The federal 25C energy credit covers 30% of the product cost, up to $600 per year on qualifying units. After a wind-mitigation inspection (roughly $75 to $150), many homeowners also see windstorm-premium credits averaging around 25% on the windstorm portion of their policy. Each program and carrier sets its own final numbers, so we can’t guarantee a specific rebate, but we can document the product ratings your inspector needs.
One honest comparison we hear often: impact windows versus hurricane shutters. Shutters require someone home to deploy them, they don’t do anything for daily energy loss or noise, and they don’t meet the same permanent-protection standard. A properly rated impact window is always protecting, even when you’re not home. For a Three Lakes primary residence, that’s the choice most homeowners make once they see the premium credits and energy savings together.

FAQs - Custom & Geometric Windows in Three Lakes
Because Three Lakes sits inside Miami-Dade County’s High Velocity Hurricane Zone, and the Miami-Dade permit counter will reject any window stamped only with Florida Product Approval. The inspector requires an active Miami-Dade NOA number on the label. Florida statewide code won’t satisfy this, and contractors from Broward or Collier miss it constantly. Call (727) 291-4678 before you order, and we’ll verify the NOA status for your exact shape and size.
Yes. We template every arch on-site and order custom radius windows that carry HVHZ large-missile ratings and Miami-Dade NOA numbers for the specific configuration. PGT and CGI both offer custom radius lines we use for this exact purpose. The curve doesn’t compromise the rating when the unit is engineered correctly.
The crust is aluminum pitting from the persistently high humidity along Three Lakes’s canal-laced drainage. It’s common in this area, but it’s not harmless. Once pitting breaks through the frame wall, air and water get behind the jamb and your wind-mitigation inspection will fail. If you’re seeing crust, schedule a free inspection rather than waiting.
Yes, especially on the west-facing and canal-facing elevations. Three Lakes’s humidity means your AC works against both temperature and latent moisture load, and leaky 1990s aluminum frames add to both. Properly sealed, low-e laminated glass reduces solar gain and air intrusion, and the federal 25C credit can offset part of the product cost.
Because we pull the Miami-Dade NOA documentation and verify the active status with the county before we order anything. We don’t start demolition until the permit is in hand and the inspector’s requirements are documented. If the NOA for your specific shape isn’t current, we’ll tell you before you spend a dollar, not after the old window is out.
