Fast, Reliable Custom Windows & Doors Across Longwood
Custom window and door work in Longwood is not a one-size job. The city holds two different building stocks at once: the Longwood Historic Village, where a Certificate of Appropriateness from the Historic Preservation Board is required before any permit gets issued, and the 1970s and 1980s CBS ranch subdivisions like Sanlando Springs and the Wekiva-area tracts, where original single-pane aluminum sliders are now failing from decades of Central Florida heat cycling and humidity. TruePane Windows & Doors handles both. If you are planning a replacement or a custom build, call (754) 238-2201 for a free estimate and a straight answer on what your specific Longwood property will require.
Why TruePane Windows & Doors Is Longwood’s Preferred Custom Windows & Doors Company
Most contractors working Longwood know how to pull a Seminole County permit. Fewer know that the Longwood Historic Village has its own approval layer before the county will even look at the job. We do, and we have been through enough Certificate of Appropriateness reviews to know which replacement windows will pass and which ones will get sent back. That distinction matters when a homeowner has already ordered units and is waiting on the board’s sign-off.
Our Custom Windows & Doors team has worked properties along Markham Woods Road, through the Sanlando Springs neighborhoods, and down to the smaller lots near West Warren Avenue. The common thread in Longwood is age: most homes here were built before impact standards tightened and before low-E glass was standard. Dale Kessler built TruePane on the rule that if the pane is not true, the job is not done. That rule applies whether we are setting a custom half-round window in a historic cottage or reframing a 1979 slider opening to modern wind-load code.
We show up in uniform, measure every opening twice, and register both manufacturer warranty layers in writing before the truck leaves the driveway. Longwood homeowners tend to be people who have lived in their house for twenty years or more. They have dealt with the contractor who left a fogged seal and stopped answering the phone. We plan to be in town in thirty years, and we act like it.
Our Custom Windows & Doors Services in Longwood
Custom Shape Windows
Half-rounds, arched tops, trapezoids, octagons, and radius units. Longwood has no shortage of these: the historic cottages near the Village use them as focal points, and the 1980s ranch homes often have a single arched window over the entry that no one stocks off the shelf anymore. We order to the exact rough opening, and in the Historic Village district we match the original lite patterns the Preservation Board requires. A custom shape costs more than a stock rectangle, typically $900 to $2,400 per unit in Longwood depending on glass package and frame material, but it is the only way to keep the architectural line of the house intact.

Commercial Storefront Glazing
Longwood’s small commercial corridors, including the storefronts along West State Road 434 near the historic downtown, need storefront glass that meets current impact and energy requirements without looking like a chain retrofit. We replace narrow stile aluminum storefronts, single tempered lites, and damaged entry transoms, and we coordinate with property owners on Seminole County commercial code. Most Longwood storefront replacements run $85 to $160 per square foot installed, with lead times on commercial hardware running two to six weeks for non-stocked framing.

Curtain Wall Systems
Curtain wall is less common in Longwood than in larger commercial centers, but when an office building or a church fellowship hall on the east side of town needs it, the work has to be planned around wind-load calculations and anchoring details that a standard window crew does not touch. We handle the engineering review, the anchor schedule, and the glazing in sequence so the building stays weather-tight during the job. Curtain wall work in Longwood typically starts around $15,000 for a modest elevation and climbs from there.

Architectural Grilles & SDLs
Simulated divided lites are the difference between a replacement window that looks correct and one that looks like a cheap swap. This is especially true in the Longwood Historic Village, where the Certificate of Appropriateness review will not approve flat snap-in grilles between the glass if the original window had true divided lites or a specific muntin profile. We spec grilles that match the existing sightlines, including wider colonial profiles for Craftsman-era homes. Grille and SDL upgrades add $90 to $240 per sash depending on profile and finish, and in the Village zone they are often mandatory, not optional.

Oversized Glass Panels
Longwood has its share of large fixed windows, picture windows, and sliding glass walls, particularly in the newer and custom-built homes along the Wekiva side of the city and on acreage lots off Markham Woods Road. A 96-inch tempered low-E picture unit in Longwood runs $2,800 to $5,500 installed, and a large sliding door with custom glazing can run $6,000 to $12,000. These jobs take longer to order and need two or three crew members to set safely. We scope access, slab thickness, and header condition before quoting.

Trusted Brands We Service in Longwood
We are an authorized installer for more than a dozen manufacturer lines, and on Longwood jobs we lean on a few brands that fit the local conditions well: Andersen for full-frame window replacement on historic and high-end homes, ViewLux for custom impact-rated casements and oversized panels, and ES Windows for a European-thermal frame that handles Central Florida humidity well. If you already own a line we carry, we register the warranty in your name and keep the paperwork current. That is the Keystone Standard, and it is the same on a single replacement window or a whole-house order.
Common Custom Windows & Doors Problems We See in Longwood Homes
- Air leaks on original 1970s and 1980s aluminum sliders. The frame corners loosen from daily heat-cool cycling, and the weep holes clog with pollen and dust from the live oaks around Sanlando and the Wekiva tracts. The sash then sits crooked in the track and lets air past the brush seals even when the window is closed.
- Rotted jambs and failed flashing tape on original exterior doors. Longwood’s afternoon thunderstorms dump water fast, and the high humidity means any gap behind the jamb stays wet. We regularly pull a door in a CBS ranch home and find the rough opening soaked and the original builder’s flashing tape peeling.
- Red-tagged replacements in the Historic Village. A homeowner installs a standard vinyl double-hung without going to the Historic Preservation Board first, and the permit gets challenged. The units then have to be pulled and replaced with profiles the board will actually sign off on. This is the most expensive mistake we see in Longwood because it is entirely avoidable.
- Fogged insulated glass from seal failure. The UV load and daily temperature swings in Central Florida degrade glazing seals faster than the national average. On original 1970s tract home windows, two panes with a failed seal mean the unit is shot, and on Longwood homes with odd shapes or large lites, the replacement is not a stock size.
Pricing for Custom Windows & Doors in Longwood, FL
Longwood pricing leans higher than nearby Winter Springs or Casselberry on historic-home work because the Certificate of Appropriateness process adds time and limits material choices. A full custom window replacement on a 1970s CBS ranch in Longwood typically runs $14,000 to $38,000 depending on unit count, impact or non-impact ratings, and whether exterior doors are included. A commercial storefront glazing job starts around $8,000. A single oversized picture unit runs $2,800 to $5,500. What changes the price most on Longwood jobs: Historic Village compliance requirements, the condition of the existing rough openings, whether the home has original hollow-core exterior doors that need reframing, and the distance from our dispatch point to the job site. We quote on paper with line items, side by side across manufacturer lines when you want to compare, and we do not add change orders after the contract. Call (754) 238-2201 for a free estimate, and we will bring the measurements and the straight numbers.

FAQs - Custom Windows & Doors in Longwood
Yes, if your home sits in the Longwood Historic Village district, you need a Certificate of Appropriateness from the city’s Historic Preservation Board before Seminole County will issue the building permit. The board reviews lite patterns, profiles, and materials, and standard off-the-shelf vinyl double-hungs often fail the review. We can walk your project through the board process and spec windows that will pass. Call (754) 238-2201 for help before you order anything.
Original aluminum sliders from the 1970s and 1980s leak air because the frame corners loosen over decades of heat-cool cycling, and the brush weatherstripping compresses into hard plastic strips. Once the corner joints move, the sash is no longer square in the track, and air passes regardless of the lock position. This is a replacement-level problem, not a caulk fix. Call us for a free measurement and a fixed quote.
Yes. Longwood is inland, so impact-rated units are not code-mandated the way they are in Miami-Dade or Broward, but many Longwood homeowners choose them anyway for storm debris protection and insurance discounts. We install impact-rated windows from PGT, and CGI, and we will show you the cost difference against non-impact low-E units on paper. Call (754) 238-2201 for side-by-side pricing.
Fog between the panes means the insulated glass unit’s seal has failed. Longwood’s UV load and daily temperature swings stress seals harder than the national average, and once the seal fails the inert gas is gone and the unit is not energy-efficient anymore. The fix is replacement of the glass or the whole sash, not a cleaning. We can match the lite pattern and frame profile, including Longwood Historic Village units that need board approval.
On acreage lots off Markham Woods Road and around the Wekiva area, we verify septic drain field and well locations before staging equipment, and we keep the work sequence clear of any setbacks. We also check slab elevation and drainage when we replace ground-level windows and doors, so the new sill pans drain away from the slab and not into the house. Longwood acreage jobs often include outbuildings or detached structures, and we scope those separately. Call (754) 238-2201 and we will walk the site with you before quoting.
