Trusted Custom & Geometric Windows for Miami Beach Homeowners
Custom and geometric windows in Miami Beach typically cost $1,200 to $6,800 per opening depending on glass, framing, coatings, and whether impact rating is required. TruePane Windows & Doors has installed and serviced shaped windows across Miami Beach, North Bay Village, and Surfside since 2008, with most custom work quoted in a single visit. If you need an arched transom rebuilt, a trapezoid impact unit fitted to an existing opening, or a full wall of geometric glass engineered for wind load, we measure twice, quote manufacturer lines side by side on paper, and register both warranty layers before the truck leaves the driveway. Call (386) 406-9359 to talk to a live person about your project.
What Our Custom & Geometric Windows Service Includes
Custom Impact Windows
Custom impact windows are engineered to Miami-Dade and Florida Building Code wind-load requirements and built to fit openings that stock units simply cannot. In Miami Beach, where waterfront exposure on Allison Island or along Pine Tree Drive changes pressure ratings from one block to the next, a custom line item is often the difference between a permitted install and a failed inspection. We measure the rough opening, review the existing framing for rot or termite intrusion, and quote PGT, CGI, ES Windows, and CWS side by side so you see the actual cost per manufacturer before any contract is signed.

Geometric & Shaped Windows
Geometric windows include triangles, trapezoids, parallelograms, octagons, and radius combinations that fall outside standard rectangle production lines. These units are common in mid-century Miami Beach homes, particularly in the Normandy Isles and La Gorce neighborhoods, where original trapezoid and angle-wall glass from the 1950s and 1960s now fails at the seal or the frame. TruePane works with manufacturers that still produce true shaped glass, not angle-cut approximations, which matters when the existing sash groove is 5/8 inch and the new unit must seat clean without a caulk-and-hope fix. We also handle reglazing for shaped sashes where the frame is sound but the insulated glass unit has fogged.

Arched & Curved Windows
Arched and curved windows are radius units, from simple half-round transoms to full eyebrow arches that require a curved frame, curved glass, and a curved stop bead. Miami Beach homes along Prairie Avenue, Pine Tree Drive, and the Venetian Islands carry a lot of these profiles from the 1920s through the 1960s, and when the lower sash is replaced, the radius transom above it often gets ignored because it is expensive to reproduce. We quote arched units with exact radius dimensions, measured across the chord and the rise, so the replacement matches the existing curve rather than approximating it. The manufacturer sends a curved template before production, and we verify it against your opening before glass is cut.

Oversized Openings
Oversized openings are glass wall conditions that exceed the standard maximum for stock production, usually anything over 40 square feet in a single unit or mulled assembly. In Miami Beach condo towers and newer spec homes in the Sunset Islands, these openings run from floor to ceiling and carry both wind-load and deflection limits that stock residential windows do not meet. TruePane has installed oversized fixed and operable units that require laminated glass, heavier frames, and sometimes steel reinforcement in the mullions, and we coordinate with structural engineers when an existing header or lintel needs attention before the new unit goes in. The work is not rushed; every oversized opening is measured by two technicians on the same visit, and the quote includes the manufacturer’s engineering review fee so there are no surprise line items later.

Brands We Service for Custom & Geometric Windows
We service and install CWS and ES Windows shaped units regularly across Miami Beach, from replacement sashes in older co-op buildings to complete custom window packages in new construction. With CWS, we work directly with their custom geometry department to produce radius and polygon units that match existing historical profiles, and we have replaced enough CWS impact glass to know the frame tolerances and the hardware adjustments that a new install requires. With ES Windows, the value is their thinner profile on modern architecture, and we have installed their fixed and casement shaped units in waterfront homes where the client wants maximum glass area without a fat frame breaking the sightline.
We also service ECO Window Systems and Mr-Glass units when a homeowner has an existing custom installation that has failed at the seal, the operator, or the weatherstripping. ECO’s thermally broken aluminum shaped units occasionally need glass replacement or re-balancing on oversize sashes, and Mr-Glass geometric windows show up in a number of Miami Beach spec builds from the last fifteen years where the original installer is no longer answering the phone. Whether you have one of these brands or any other make, we can evaluate the unit, quote what makes sense to repair versus replace, and register the manufacturer warranty in writing when a new unit goes in.
Signs You Need Custom & Geometric Windows Right Now
- Water staining under a shaped window after a storm. This means the flashing or the seal has failed at a non-standard corner, and shaped windows fail at the point where the radius meets the straight leg far more often than square units. In Miami Beach’s wet season, water that gets behind the frame rots the rough opening and can spread into the ceiling joist within a season.
- Fogging between panes in a trapezoid or arch unit. The insulated glass seal has failed, and shaped units are not a stock replacement item at a home center. Once fog shows, the glass is losing its thermal and acoustic performance, and in coastal conditions the failure usually accelerates as salt air works into the spacer.
- Visible cracks in the frame corner of any geometric sash. Shape corners concentrate stress, particularly in triangle and parallelogram units where the angles are sharp. A cracked corner is a structural issue, not a cosmetic one, and in an impact-rated opening it also voids the manufacturer’s rating for that unit.
- Difficulty opening or a shaped sash that drops when released. Balances on shaped windows wear faster because the sash weight distribution is uneven. When an arched or trapezoid window will not stay open, the hardware is telling you something, and forcing it leads to a dropped sash and broken glass.
- You are planning a remodel and the existing openings are non-standard sizes. Rather than reframe every opening to fit a stock window, which costs more in framing, drywall, stucco, and paint than most owners expect, we can quote the manufacturer’s custom geometry to fill what is already there. This matters in Miami Beach historical districts where altering an existing opening may trigger design review.
Our Custom & Geometric Windows Process - Step by Step
- 1
Call to schedule an on-site measurement. You talk to a live person, not a call tree. We ask about the openings, the age of the house, whether there are visible leaks or fogged units, and what you are trying to solve. Then we set an appointment time that we keep, with a uniformed technician who carries a laser measure, a moisture meter, and a manufacturer spec book.
- 2
Full opening measurement and condition report. The technician measures every dimension twice: diagonal, chord, rise, frame depth, and rough opening. They also inspect the surrounding framing, check for moisture intrusion with a meter, and document the existing condition with photos. For arched units, we take a template of the curve so the manufacturer can match the exact radius. You get a written report covering what exists and what the replacement requires.
- 3
Side-by-side quote review with manufacturer options. We bring the numbers to you on paper, with each manufacturer line item separated so you see the actual cost difference between PGT, CGI, ES Windows, and CWS. This includes glass package, frame finish, hardware, and any engineering review fee. There are no change orders down the road because we quoted the right unit the first time. The Keystone Standard applies here: both warranty layers are registered in writing, with durations stated, before you sign.
- 4
Install day with head-of-household walkthrough. The crew arrives on time, lays down floor protection, removes the old unit carefully to avoid damaging the surrounding stucco or interior trim, and sets the new shaped window into the prepared opening. Every unit is shimmed and squared against the line before a single screw is driven. Impact-rated units get the required anchor pattern per manufacturer and per Miami-Dade code. We do not send a second truck out later to finish what the first crew left hanging.
- 5
Final inspection and warranty registration on site. Before the truck leaves, the lead technician walks you around the install, shows you the operation of each unit, and confirms the manufacturer warranty registration numbers with you in writing. The Done Right Promise covers the workmanship, and the manufacturer covers the product. If anything is not right over the next ninety days, we make it right, no paperwork fights and no arguing. If the pane is not true, the job is not done.
How Much Does Custom & Geometric Windows Cost in Miami Beach?
Custom and geometric window pricing in Miami Beach runs on a wide spread because the units are made to order and the particulars change the cost fast. A small fixed triangle with standard insulated glass may run $1,200 to $2,400 per unit. An arched half-round transom in impact glass typically starts around $2,500 and runs to $4,800 depending on radius and frame material. An oversized trapezoid or parallelogram in laminated impact glass with a quality aluminum frame will land between $4,500 and $6,800 per opening, and a full wall of geometric units with mullions can exceed $20,000 on a waterfront elevation. Labor, anchoring pattern, removal of the old unit, and any structural repair to the surrounding framing are all included in our written quote.
What moves the price: glass package (standard insulated versus laminated impact versus low-E with sound control), frame material (vinyl versus thermally broken aluminum), unit size, radius complexity, and whether the opening requires a retrofitted impact unit or a full frame-out with new flashing. The cheapest bid on a shaped window in Miami Beach is usually the one where the radius does not actually match and the installer caulks the gap. We avoid that by ordering from the manufacturer’s custom geometry line and verifying the curve against a template before glass is cut.

Frequently Asked Questions - Custom & Geometric Windows in Miami Beach
A custom or geometric window is any window whose shape falls outside standard rectangle production, including triangles, trapezoids, arches, circles, parallelograms, and combined shapes. These units are built to your opening’s exact dimensions rather than pulled from a production run. In Miami Beach, they are common in historical homes, mid-century designs, and contemporary waterfront builds where stock windows simply will not fit the architecture.
Most custom and geometric window orders take four to eight weeks from template approval to delivery, depending on the manufacturer and whether impact testing is required. The on-site measurement and written quote typically happen within a few days of your call. For a straight replacement where the framed opening is sound, installation itself is usually completed in one day per unit, though a wall of shaped windows may take two days.
A geometric window replacement in Miami Beach typically runs from $1,200 for a basic fixed triangle up to $6,800 for an oversized impact-rated trapezoid or arch. The main variables are glass package, shape complexity, unit size, and frame material. We give you a itemized written quote with manufacturer options side by side before any money changes hands. Call (386) 406-9359 and we’ll measure and quote your specific openings.
We service and install CWS and ES Windows shaped units regularly in Miami Beach and surrounding areas. With CWS, we work with their custom geometry department for replacement sashes and full units, and with ES Windows, we handle their thinner-profile fixed and casement shaped units. We also repair and replace ECO Window Systems and Mr-Glass custom windows when the original installer is no longer available.
A live person answers our phone 24 hours a day, 7 days a week, and we prioritize calls for broken glass and water intrusion in Miami Beach during storm season. We can board an opening temporarily when a shaped unit is breached and order the glass or unit as fast as the manufacturer allows. For a non-impact opening, we will discuss a quote for upgrading to impact-rated shaped glass while the opening is already down.
Every custom and geometric window installation from TruePane is covered by the Done Right Promise on workmanship, and The Keystone Standard governs every manufacturer warranty: both warranty layers are registered in writing, with durations stated, before the truck leaves the driveway. If something is not right within ninety days, we make it right without paper fights or fine-print arguments. That is the standard Dale Kessler set when he founded the company in 2008, and it has not changed.
Clear movable furniture away from the openings you want quoted so the technician can access the full frame and take clean measurements, and have a list ready of any windows that fog, bind, or leak. If you have an HOA or historical district approval process, mention it so we can help coordinate the paperwork. You don’t need to remove anything from the wall or expose the rough opening; we handle that on install day if the project moves forward.
