AfterFast, Reliable Impact Windows & Doors Across Mount Dora

TruePane Windows & Doors serves Mount Dora homeowners directly, and we’ve spent years working through the specific permit and preservation requirements that make this city different from Tavares, Eustis, or anywhere else in Lake County. If you’re weighing impact windows for a Craftsman bungalow near Donnelly Street or a ridge-top house off Old New England Avenue, call (813) 320-9346 and we’ll walk the property with you, measure every opening twice, and put a written quote in your hand.
Why TruePane Windows & Doors Is Mount Dora’s Preferred Impact Windows & Doors Company
TruePane was founded in 2008 by second-generation glazier Dale Kessler, and the company carries years of craft tradition into every job. Mount Dora homeowners call us because we know what happens when a contractor from outside the area doesn’t understand the city’s preservation rules or its unusual terrain. We do. Our crews have replaced rotted sashes on 1920s bungalows near the downtown lakefront, retrimmed ridge-facing doors that took on wind-driven rain, and coordinated certificates of appropriateness with the Historic Preservation Board on Donnelly Street and Old New England Avenue. The work passes inspection because we plan for the inspection before we start.
Our background-checked, uniformed technicians are trained in our own apprenticeship program, not subcontracted off a call list. When we quote a job in Mount Dora, we quote the full job: permit path, preservation review where it applies, framing, flashing, the unit itself, and both warranty layers registered in writing before the truck leaves the driveway. That’s The Keystone Standard. If something isn’t done right within 90 days, we make it right. No paperwork fights, no arguing. That’s the 90-Day Done Right Promise, and we back it in writing.
We also answer the phone. A live person picks up 24 hours a day, 7 days a week. Not a voicemail tree, not a callback form. When a Mount Dora homeowner calls with a leaking impact slider or a permit question, they talk to someone who can help.
Our Impact Windows & Doors Services in Mount Dora
Hurricane Impact Windows
Mount Dora’s pre-1950 housing stock presents a challenge most replacement window companies never bother to understand. Original single-pane wood sashes in Victorian and Craftsman homes have spent decades absorbing Lake Dora humidity. Glazing compound dries out, wood swells, seals fail, and rot hides behind the jamb where you can’t see it until the unit comes out. We size impact-rated units to the original openings, work with the Historic Preservation Board where the certificate of appropriateness applies, and set each window true. If the pane is not true, the job is not done.
Impact Sliding Glass Doors
Homes along the Lake Dora and Lake Gertrude shoreline get constant ambient humidity, and 1970s-1990s aluminum sliders in tract neighborhoods nearby develop galvanic corrosion at fastener points faster than homes set back from open water. You’ll notice the door binding in July, weatherstripping peeling, or a track that sags under its own weight. We replace those with impact-rated sliders set on repaired, level track framing and sealed properly against wind-driven rain. Most jobs are completed in a single visit.
Impact Entry & French Doors
Mount Dora sits at roughly 184 feet of elevation, unusually high for Florida. Hilltop and ridge-facing homes catch direct wind that flat-terrain homes never feel, and door thresholds are the first point of failure. We see water staining around the bottom corners, warped stiles, and hollow-core exterior doors original to 1980s construction. Our impact entry and French door replacements in Mount Dora are measured, quoted, and installed with attention to the actual wind load on that specific exposure, not a one-size-fits-all spec.
Impact Garage Doors
Garage doors in Mount Dora’s older neighborhoods are typically builder-grade and decades past their rating. During a storm, an unreinforced garage door is the largest single opening on the house, and when it goes, it takes the roof pressure with it. We install impact-rated garage doors and track bracing systems sized to the opening and the exposure. It’s not the most visible upgrade on the house, but it’s one of the most important in a wind event.
We also handle hurricane shutters and protection systems, plus wind mitigation and code compliance work, which matters more than ever in Mount Dora’s historic district where a repair or replacement triggers review. Our Impact Windows & Doors team covers the full scope.

Common Impact Windows & Doors Problems We See in Mount Dora Homes
- Rotted wood sashes in pre-1950 cottages. Original single-pane double-hungs have lost their glazing compound, and decades of Lake Dora humidity have swelled and rotted the wood behind the jamb. The frame is usually worse than the sash.
- Galvanic corrosion in aluminum sliders from the 1970s-1990s. Homes within a few blocks of open water see fastener corrosion and frame pitting that inland homes in Tavares or Sorrento won’t develop as quickly. The track sags, the door binds, the weatherstripping dies.
- Historic Preservation Board stalls. We hear from Donnelly Street and Old New England Avenue homeowners every month: they got a quote from an Orlando or Ocala company, the permit was pulled, and then the job stopped because nobody filed for a certificate of appropriateness. We file that paperwork as part of the job scope.
- Ridge and hilltop wind-load failures. Mount Dora’s elevation means hilltop homes take wind that flat-terrain homes don’t. Thresholds leak, weatherstripping rips, and some original installations were never rated for the pressure those ridges actually see in a storm.

FAQs - Impact Windows & Doors in Mount Dora
The Historic Preservation Board does allow impact windows in the designated downtown district, but it requires a certificate of appropriateness first, and standard vinyl units are routinely denied in favor of wood or aluminum profiles that match the original Victorian or Craftsman dimensions. The good news: impact-rated wood-look and aluminum-clad units meet both the wind code and the preservation standard. The bad news: you have to file the paperwork before the install, and most out-of-town contractors don’t flag that step until the permit stalls. We file the certificate as part of our scope on qualifying Mount Dora homes. Call (813) 320-9346 if you’re unsure whether your street falls inside the district.
In most pre-1950 Mount Dora homes, the sash and the frame rot together. The original jamb pockets swell, flashing tape behind the brickmold fails, and humid lake air has been wicking into the framing for decades. Replacing only the sash leaves the rot in place and the opening out of square. In nearly every Donnelly Street bungalow we’ve opened, the frame needed rebuilding too. We recently did exactly that on a 1920s Craftsman near Donnelly Street: rebuilt the openings with code-approved framing after finding undersized headers and corroded fasteners, then set Simonton impact-rated wood-look casements with low-E argon glass. The job passed the Historic Preservation Board without delay because the paperwork was filed upfront. Call (813) 320-9346 and we’ll inspect the window before we quote you a number.
Mount Dora’s permit path is not the same as Orlando’s. On any job in the designated historic district, the city requires a certificate of appropriateness before installation. Many outside contractors don’t know that until the permit stalls, and then the quote changes because they’re now paying for preservation review, code upgrades, and rebuilt framing. The permit also triggers code inspections that can require upgrading outdated wiring or undersized framing once walls are open. That’s the single biggest reason a Mount Dora window quote moves. We write those allowances into the contract on the front end, and any surprise is priced and approved in writing before we touch it. That’s a square deal, and it’s why our quotes hold. Call (813) 320-9346 for a written estimate that accounts for Mount Dora’s actual permit path.
Mount Dora sits at roughly 184 feet of elevation, which is high for Florida. Ridge-facing and hilltop homes take direct wind exposure that flat-terrain homes in Tavares or Eustis never see, and that concentrated wind pushes water into door thresholds and weatherstripping much harder. We size doors and flashing for the actual exposure on your specific lot, not a generic Lake County spec. If you’re on a ridge off Old New England Avenue or a hilltop near the lakes, your impact door needs a higher design pressure rating and better pan flashing than a home in the flats. Call (813) 320-9346 and we’ll walk the exposure with you before quoting.
U-factor measures how well a window resists heat transfer through the glass and frame. SHGC, or solar heat gain coefficient, measures how much solar radiation passes into the house. In Mount Dora’s humid Lake County climate, you want both numbers working for you: a low U-factor to keep the cool air in during summer and a SHGC tuned to the orientation of each window. South- and west-facing windows take more afternoon sun and should carry a lower SHGC than north-facing units. We spec glass packages per opening, not per house, because a lakefront window on Lake Dora and a shaded window on a tree-lined street in the historic district need different numbers. Call (813) 320-9346 and we’ll pull the glass specs side by side so you can see exactly what you’re buying.
