AfterFast, Reliable Custom Windows & Doors Across Lake Mary
If you own a home in Lake Mary built between 1988 and 2005, there’s a good chance your original windows are reaching the end of their service life. Builder-grade aluminum frames from that era corrode at the sills in our humidity, and the arched transom windows that define Heathrow and Timacuan homes rarely match any modern impact-rated size on the shelf. Custom windows and doors for Lake Mary homes start around $850 for a standard custom double-hung and run $4,500 to $12,000 for impact-rated arched transoms with oversized glass. Call TruePane Windows & Doors at (954) 280-4413 for a free estimate, and we’ll walk you through what Seminole County and your HOA will actually require before we quote a single line item.
Why TruePane Windows & Doors Is Lake Mary’s Preferred Custom Windows & Doors Company
We’ve done enough work in Lake Mary to know the lay of the land before we ever pull up to the house. Our crews are familiar with the Architectural Review Committee processes in Heathrow, Timacuan, Chase Groves, and The Crossings, and we don’t get thrown when a two-story great room has a 1994-vintage arched window that no manufacturer catalogs anymore. Dale Kessler founded TruePane in 2008 on a rule that still hangs in our shop: if the pane is not true, the job is not done. That’s why every custom window or door we sell carries the Done Right Promise, and why both warranty layers from the manufacturer get registered in writing before we leave your driveway.
We’re not the cheapest bid you’ll get in Lake Mary, and we won’t pretend otherwise. What we offer is a square deal: background-checked, uniformed technicians who measure every opening twice, quote manufacturer lines side by side on paper, and pull the Seminole County permit with the HOA paperwork already in order. A live person answers our phone 24 hours a day, seven days a week. When you call about a fogged transom over your entry door, you talk to a person who knows what an IGU is, not a voicemail tree.
Our Custom Windows & Doors Services in Lake Mary
TruePane installs, replaces, and services Custom Windows & Doors throughout Lake Mary, with a focus on the non-standard work that other companies decline. Most of our Lake Mary jobs fall into one of the categories below.
Custom Shape Windows
Arched, palladian, eyebrow, radius-top, circle-top: these shapes were standard features in late-1980s and 1990s Lake Mary luxury construction, and they’re the first units to fail because the original aluminum frames had no real thermal break. We template every custom shape on site, order an impact-rated IGU with low-E glass and argon fill, and install with a fusion-welded sash that matches the original radius. If the shape is off by a quarter inch, the seal will fail. We don’t guess.
Commercial Storefront Glazing
For Lake Mary storefronts and office suites, we handle aluminum storefront framing, impact-rated glass replacement, and entrance door retrofits that meet Florida Building Code wind-load requirements. We’ve replaced shattered impact glass on retail frontages along Lake Mary Boulevard and Rinehart Road, and we coordinate with your landlord or property manager on after-hours scheduling so your business isn’t dark during a workday.
Curtain Wall Systems
Lake Mary’s newer commercial and institutional buildings, including medical offices along International Parkway, use curtain wall systems with large glass spans. We install and replace curtain wall components including mullions, pressure plates, and gaskets, and we source oversized glass panels that meet the same wind-borne debris requirements as residential work. Curtain wall leaks in Central Florida are almost always a failed gasket or an improperly flashed transition, and we trace the leak before we order a single replacement unit.
Architectural Grilles & SDLs
If you want the divided-light look on a Heathrow colonial or a Timacuan Mediterranean, we supply and install simulated divided lites (SDLs) in both interior and exterior configurations, permanent or removable. SDL bars applied to impact-rated glass give you the architectural look without compromising the structural rating. We carry grille patterns from more than a dozen manufacturers, including Andersen, Pella, Marvin, PGT, CWS, and ES Windows, and we’ll show you side-by-side samples on paper before you commit.

Trusted Brands We Service in Lake Mary
TruePane is an authorized installer for more than a dozen manufacturer lines, and for Lake Mary work we most often quote CGI, CWS, and ES Windows because their impact-rated custom configurations cover the arched and oversized openings common in Heathrow and Timacuan. When you work with our Lake Mary team, we register both warranty layers, state the durations in writing, and keep your paperwork on file. If a seal fails or a grille rattles two years from now, we stand behind it. We stock common replacement parts for these brands locally, which means a broken latch or fogged sash doesn’t wait on a freight shipment.
Common Custom Windows & Doors Problems We See in Lake Mary Homes
- Corroded aluminum frames at the sill. Homes built in the 1988-2005 boom typically used builder-grade aluminum frames with no meaningful thermal break. After 20 to 35 years of Central Florida humidity, the sills oxidize and the corners rot, which lets water in and causes the glass seal to fail.
- Arched transom windows with no impact-rated replacement. Two-story great rooms in Heathrow and Timacuan have tall arched transoms that were custom-built in the 1990s and were never manufactured in standard impact-rated sizes. Replacing one means a templated custom IGU and, usually, a four to eight week wait while the HOA reviews the permit.
- Fogged dual-pane glass in oversized panels. Lake Mary’s UV index is among the highest in the continental US, and it degrades vinyl frames and accelerates seal failure faster than manufacturers’ projections. Oversized picture windows facing west or south tend to fog first.
- Failed sliding glass door thresholds. Afternoon convective storms dump water at the base of older sliding doors, and original aluminum thresholds warp and channel water into the interior floor. This is a persistent problem in pool-lanai doors and second-story balcony sliders throughout Lake Mary.
Pricing for Custom Windows & Doors in Lake Mary, FL
Here’s what you can expect to pay in Lake Mary for custom work, based on recent jobs we’ve completed in Heathrow, Timacuan, and Chase Groves:
- Standard custom double-hung window: $850-$1,400 per unit installed
- Impact-rated custom casement or awning: $1,200-$2,200 per unit installed
- Arched or palladian transom, custom IGU: $4,500-$12,000 per unit, depending on size, shape, and HOA constraints

These ranges include both Seminole County permit fees and HOA documentation, which is where cheap quotes fall apart. A low bid that omits the Architectural Review Committee application or the wind-load certification isn’t a lower price; it’s an incomplete job that will stall or fail inspection.

FAQs - Custom Windows & Doors in Lake Mary
Yes. Lake Mary is inland, but it still falls under Florida Building Code wind-borne debris requirements, which means any new window or door installation must use impact-resistant glazing or an approved storm protection system, period. There is no exemption for Heathrow, Timacuan, or any other Lake Mary neighborhood. A compliant quote will always list the design pressure rating and the product approval number. If a contractor’s quote doesn’t include both, the work won’t pass a Seminole County inspection. Call (954) 280-4413 if you want to see exactly what a compliant quote looks like.
Seminole County requires a product approval number for every window and door that enters the permit application, and the plan reviewer checks the design pressure rating against the specific wind zone for your Lake Mary address. Orange County has a similar standard, but Seminole’s reviewers have historically been stricter about non-standard shapes like arched transoms, which means your custom IGU needs a documented engineering evaluation, not just a manufacturer’s catalog sheet. We submit this paperwork with the permit. It’s part of what you’re paying for. Call (954) 280-4413 for a quote that includes this step.
The biggest mistake is ordering a standard impact unit first and discovering it doesn’t match the rough opening, the radius, or the HOA’s design standards. Arched transoms in Heathrow and Timacuan were custom-built in the 1990s, and there is no standard replacement. The correct sequence is: template the opening, get HOA Architectural Review Committee approval, then order the custom IGU. Skipping the HOA step stalls the job for four to eight weeks while your old window leaks. We handle the sequence in the right order, every time. Call (954) 280-4413 before you order anything.
They matter a great deal. If a Lake Mary homeowner files a claim for storm damage and the insurance adjuster finds that the replacement window was never documented with a wind-load rating or a product approval number, the claim can be reduced or denied on the grounds of improper installation. We provide both manufacturer warranty layers registered in writing, plus the product approval documentation, so your insurance file shows a compliant install. That’s the kind of documentation a cheap bid never includes. Call (954) 280-4413 and we’ll show you the paperwork we provide on every Lake Mary job.
Because the 1988-2005 building boom in Lake Mary produced a lot of two-story great rooms, picture windows, and transom-topped openings that were sized to architectural drawings, not to manufacturer catalogs. A ten-foot-wide picture window in a Timacuan living room or a towering arched transom in a Heathrow entry has no standard impact-rated equivalent. Oversized glass panels have to be templated, fabricated, and shipped as custom units, which is slower and more expensive but the only way to keep the look of the house while meeting Florida Building Code. We quote oversized glass work with the templating, fabrication, and freight built into the price. Call (954) 280-4413 for a free estimate.
