Fast, Reliable Custom & Geometric Windows Across Andover
Custom and geometric windows in Andover almost always come down to one issue: the original openings in these 1955–1975 CBS homes were never built to modern hurricane-code dimensions. A standard impact window won’t fit, and forcing one in compromises the concrete lintel and fails HVHZ inspection. Winslow Windows & Doors measures every opening individually, handles the masonry work when needed, and installs custom-shaped impact units that carry a Miami-Dade Notice of Acceptance. That’s the difference between a window that satisfies your insurer and one that gets flagged on reinspection. Call (844) 901-4551 for a free in-home measure and written quote.
Key Takeaways:
- Every custom or geometric impact window in Andover must carry a Miami-Dade NOA or Florida Product Approval. No exceptions, even for a single arched unit.
- Original jalousie and aluminum-slider rough openings in 33023 rarely match modern frame sizes. Expect masonry modification on most 1955–1975 homes.
- Typical custom impact window pricing in Andover runs $1,100–$2,800 per unit installed; oversized arched or curved openings run $2,500–$5,000.
- Winslow pulls permits, schedules inspections, and provides the documentation Andover insurers demand during non-renewal reviews.
- Free in-home measure and written line-item quote. No trip charge inside our home county.
Why Winslow Windows & Doors Is Andover’s Preferred Custom & Geometric Windows Company
Ed Winslow put his name on this business in 2011, and that’s the level of accountability Andover homeowners get on every custom window job. We’re not a faceless chain with a rotating crew of subcontractors. Every technician who shows up at your door on NW 53rd Avenue or anywhere in the 33023 ZIP is background-checked, uniformed, and has already been briefed on your specific opening measurements before the truck pulls up.
Andover’s housing stock is its own animal. We’ve measured and retrofitted enough of these mid-century CBS ranches to know that the arched window on the front elevation rarely matches the framing behind it. That’s why we start with a structural inspection, not a sales pitch. If the header is undersized or the flashing has rotted into the jamb, we tell you before we quote. No vague allowances, no surprise change orders. Our Custom & Geometric Windows team writes every material and labor line into the contract, so you see exactly what you’re paying for. And because Ed’s name is on the door, a live person answers when you call, 24 hours a day. We’re the one down the road, not a ticket number in a call center queue.
Our Custom & Geometric Windows Services in Andover
Custom Impact Windows
In Andover, “custom” usually means the opening is non-standard, not that the homeowner wanted something decorative. A 1960s CBS home with original jalousies has rough openings that were framed for louvered glass, not modern impact-rated units. We measure each opening in three dimensions, spec the frame to the exact millimeter, and fabricate through trusted manufacturers we’re authorized to install. Every unit carries the Miami-Dade NOA your insurer will ask for during a wind-mitigation review. Typical per-window installed cost in Andover runs $1,100–$2,800, depending on opening size and masonry scope.

Geometric & Shaped Windows
Trapezoids, triangles, pentagons, and radius combinations are common on Andover’s mid-century front elevations. The problem is that the original aluminum frames were never engineered for wind pressure, and the glass was often annealed, not laminated. We replace these with impact-rated geometric units cut to your exact angles and matched to your home’s existing sightlines. On a 1960s ranch off NW 53rd Avenue, our crew found a geometric front window opening that had been hacked wider decades ago with no header support. We re-framed it in masonry, installed a custom PGT unit with Miami-Dade NOA, and rebuilt the flashing. The homeowner’s insurer dropped their non-renewal notice. That’s the work we do in Andover regularly.

Arched & Curved Windows
Arched windows are the most failure-prone opening type in Andover’s CBS homes. The curve concentrates wind pressure unevenly, and when old flashing gets reused instead of replaced, water finds the jamb-to-masonry interface within a few years. We fabricate true-radius impact units, not segmented approximations, and we always replace the flashing, sealant, and interior trim as part of the job. Expect $1,800–$4,200 per arched unit installed in Andover, with the higher end reflecting masonry reframing and lintel stabilization.

Oversized Openings
If you have a living-room picture window or a wide front-elevation opening that was “opened up” during a 1970s remodel, the framing behind it is likely undersized for HVHZ wind loads. We install oversized impact windows and sliding glass door combinations that carry design pressures matched to your specific wind zone, which in Andover means at least the standard required for Broward County’s High Velocity Hurricane Zone. These jobs run $2,500–$5,000 per opening, and we pull permits and schedule inspections so the work passes on the first call.

Trusted Brands We Service in Andover
We install and service windows from CWS, CGI, and ES Windows, three manufacturers whose impact-rated lines are engineered for South Florida wind zones and supported by real Miami-Dade NOA documentation. We keep common gaskets, balances, and hardware for these brands stocked locally for Andover customers, so a worn operator or failed seal doesn’t mean waiting weeks for a part from Georgia. If you have a custom-shaped unit from another brand and need straight answers about repair versus replacement, call us. We’ll give you an honest assessment. Our Done Right Promise applies to every repair and every new installation: if it’s not done right, we make it right. Period.
Common Custom & Geometric Windows Problems We See in Andover Homes
- Original jalousie rough openings that don’t fit modern impact units. We see this on nearly every 1955–1975 CBS home in the 33023 ZIP. The openings are too small or irregular, and shoving a generic window in means cutting into the concrete lintel, which is a structural failure waiting to happen.
- Salt-corrosion failure at the jamb-to-masonry interface. Andover sits 6–8 miles inland, close enough for salt-laden Atlantic air to corrode aluminum frames within 10–15 years. When old flashing is reused during a replacement, the new window develops leaks within a couple of rainy seasons.
- Premature fogging on laminated glass interlayers. South Florida UV and humidity are brutal on glazing seals, and Andover’s exposure is no exception. We replace fogged IGUs and re-laminate where the design pressure rating is still valid, and we’re honest when full replacement is the better financial call.
- Unpermitted arched openings from 1970s remodels. We regularly find oversized arched windows that were never permitted, with undersized headers and water damage behind the trim. These need structural reframing before any new window goes in, and we handle the permit and inspection so the work is actually code-compliant.
Pricing for Custom & Geometric Windows in Andover, FL
Custom impact windows in Andover typically run $800–$1,500 per unit for standard rectangular openings. Arched and geometric units add fabrication complexity, pushing the range to $1,800–$4,200 installed. Oversized openings and combinations with sliding glass doors run $2,500–$5,000 or more. Whole-home packages on Andover’s 3/2 CBS ranches usually land between $8,000 and $25,000 depending on opening count, masonry scope, and frame material. The big price movers here: whether your rough openings need masonry modification, how many openings are non-standard, and which manufacturer you choose. CWS and CGI are both excellent mid-range options; ES Windows runs higher for architectural profiles. Every quote we write is a fixed, line-item price. You approve the numbers before we order a single unit. Call (844) 901-4551 to schedule your free in-home measure and get a written quote you can actually plan around.

What Custom & Geometric Windows Costs in Andover
Impact windows in Andover run $800–$1,500 per window installed for standard rectangular openings. Impact single-hung units run $900–$1,800. Large or custom-shaped openings, which are the norm in this 1955–1975 housing stock, run $2,500–$5,000. Whole-home packages start around $8,000 and climb above $25,000 for homes with multiple arched, geometric, or oversized openings. The variables that move the price here: how many openings need masonry modification, what design pressures your specific wind zone requires, and whether you choose standard Low-E impact glass or a premium laminated product like CWS or ES Windows. We provide a free in-home measure and a written, itemized quote before you commit to anything. You’ll know the exact number, not a ballpark.
Florida Pays You Back
Andover homeowners replacing original jalousie or single-pane sliders with impact-rated custom windows can stack several incentive programs. The My Safe Florida Home program 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 product cost, up to $600 per year on qualifying units. And after a wind-mitigation inspection ($75–$150), most Andover homeowners see windstorm-premium credits averaging around 25% on the windstorm portion of their policy. Programs and carriers set the final numbers, so we can’t guarantee your exact credit, but the documentation we provide after every install is exactly what inspectors and insurers ask for. Between the rebates and the premium reduction, the real cost of a full impact upgrade in Andover is usually far below the sticker price. Big-box retail installs don’t walk you through this stack. We do. Impact windows also beat hurricane shutters for permanent protection: no panels to store, no hardware to maintain, and no scramble when a watch is posted at 2 a.m.

FAQs — Custom & Geometric Windows in Andover
Yes. Every impact window or door in Broward County, including all of Andover’s 33023 ZIP, must carry a Miami-Dade Notice of Acceptance or Florida Product Approval, regardless of shape. An arched window is subject to the same HVHZ wind-load standards as a rectangular one, and a unit without NOA documentation will fail inspection and may void your insurer’s wind-mitigation discount. Every custom window we install in Andover carries the proper NOA for its exact configuration. Call (844) 901-4551 if you’re uncertain whether an existing unit qualifies, and we’ll check it during your free estimate.
Almost certainly. Jalousie rough openings in 1955–1975 CBS construction are smaller and more irregular than modern impact frame dimensions, and cutting into the concrete to widen them without proper lintel work weakens the structural wall. We assess each opening individually, and when masonry modification is needed, we do it ourselves to code, not by subbing it to a handyman. That’s one reason our quotes for Andover homes sometimes run higher than for newer wood-frame construction in neighboring cities. Call (844) 901-4551 and we’ll measure your openings for free and tell you exactly what’s required.
Andover sits close enough to the Atlantic that salt-laden air accelerates aluminum frame corrosion within 10–15 years, especially at the jamb-to-masonry interface where old flashing traps moisture. On geometric and arched units, the angled joints are the first to show corrosion, because they hold water longer after rain. We use marine-grade fasteners, replace all flashing and sealant on every install, and recommend frame-and-glass combo replacements rather than glass-only swaps for Andover homes. If you’re already seeing white powder or pitting on your window frames, call (844) 901-4551 for a free inspection before the corrosion reaches the structural anchors.
Yes, meaningfully. Single-pane aluminum sliders conduct heat into the house all day, and in Andover’s summer, that means your AC runs longer against solar gain through every window. Modern Low-E impact glass cuts that solar heat transfer by a substantial margin, and the laminated interlayer actually dampens heat as a secondary benefit. You should see a real reduction in cooling cost after a full-home replacement, though the exact number depends on your AC’s efficiency, your insulation, and how many openings face west. We can’t quote a precise percentage until we see your layout, but a full impact upgrade in Andover also drops your windstorm premium, so the window package pays back from two directions. Call (844) 901-4551 and let us size it for your home.
Yes, and this is one of the most common jobs we take on in Andover. Unpermitted 1970s arched openings usually have undersized headers and failed waterproofing, which means the structural work has to happen before any window is ordered. We reframe the opening in masonry, install a properly sized header, install the custom geometric impact unit with full Miami-Dade NOA documentation, and pull the permit ourselves. The inspection gets scheduled by us, and we stand there while it happens. Once it passes, your insurer gets the documentation that puts the opening back into compliance. Call (844) 901-4551 for a free in-home assessment, and we’ll tell you exactly what structural work the opening needs.
