Fast, Reliable Impact Windows & Doors Across Mount Dora
Impact windows and doors in Mount Dora typically run $85-$145 per square foot installed for most homes, with historic district projects landing closer to $150-$220 per square foot once Historic Preservation Board requirements enter the picture. The work usually takes one to three days for a standard opening, and we schedule every job with a written line-item quote before the first tool comes off the truck. If you’re watching a paint-sealed sash or a jalousie unit that rattles when the wind comes off Lake Dora, call (954) 280-4413 for a free estimate.
Mount Dora is not Tavares or Eustis. The housing stock is different, the permitting path is different, and the failure patterns around the lake are different. Our Impact Windows & Doors team has worked on Craftsman bungalows inside the historic district, 1960s block homes with undersized jalousie openings, and lakefront properties where the ground fog eats bottom rails from the inside out. You need a contractor who reads this town the way a glazier reads a frame.

Our Impact Windows & Doors Services in Mount Dora
Hurricane Impact Windows
Impact-rated windows in Mount Dora have to do two jobs at once: hold the building envelope against wind gusts that hit harder on this ridge than on the flat ground around it, and meet the Historic Preservation Board’s compatibility standards if you’re inside the National Register district. We spec both sides of that equation. On pre-1940 homes we use simulated true divided lights and period-appropriate profiles, and on newer construction we focus on the right design pressure rating for your elevation and exposure. A typical retrofit in Mount Dora runs $850-$1,400 per opening depending on size, glazing, and whether reframing is required.

Impact Sliding Glass Doors
Sliding glass doors facing Lake Dora or the Dora Chain of Lakes take more wind and more humidity than doors set back from the water. We replace older sliding units with impact-rated systems that seal tight and operate smoothly even after years of lake air. Most Mount Dora installations run $2,800-$5,200 for a standard 6-foot opening, including the old door removal and new flashing. If the rough opening was never framed square, we fix that before we set the new door, because a square door in an out-of-square hole is a warranty claim waiting to happen.

Impact Entry & French Doors
Entry doors and French doors on Mount Dora historic homes are often original, which means solid wood, slightly out of plumb, and carrying a century of paint. Impact-rated replacements don’t have to look like a bunker. We install fiberglass and wood-clad impact entry systems that hold a design pressure rating while matching the proportions of the original opening. On a 1920s Craftsman on McDonald Street, we replaced the original front entry with an impact-rated unit that kept the divided-light look and the proportions. The homeowner got a door that meets code and still belongs to the house. Expect $2,400-$5,800 for entry doors and $4,000-$9,000 for paired French doors, including hardware and weather sealing.

Impact Garage Doors
Garage doors are the most common point of failure in a wind event, and Mount Dora’s older homes often have builder-grade doors that were never braced or rated. We install impact-rated garage doors and reinforce existing doors with bracing systems that meet current Florida Building Code requirements. A single-bay impact garage door in Mount Dora typically runs $2,200-$4,600 depending on size and insulation. If you’re not sure whether your current door is rated, we’ll check it during the estimate.

Trusted Brands We Service in Mount Dora
We’re an authorized installer for more than a dozen manufacturer lines, and we stock parts for the brands most common in Mount Dora: CGI, PGT among them. When a Mount Dora homeowner calls with a fogged seal or a failed latch on a brand we carry, we can often get parts without waiting on a regional warehouse. We quote manufacturer lines side by side on paper so you can see the price difference and the warranty difference in plain English. For historic homes, we lean on Marvin’s simulated true divided light options and PGT’s impact-rated profiles. For concrete-block ranches, we spec CGI and ECO Window Systems where they fit the rough opening without forcing the frame.
Common Impact Windows & Doors Problems We See in Mount Dora Homes
- Historic district permitting stalls. Contractors who skip the Historic Preservation Board submittal leave homeowners with non-refundable deposits and no legal path forward. We run the HPB approval before we pull the permit, and we carry it through to the end.
- Bottom-rail rot from lake-driven ground fog. North- and west-facing original wood windows near Lake Dora rot from the bottom rail up because of persistent ground fog, not roof leaks. Misdiagnosing this as a flashing failure leads to repairs that return within a few seasons.
- Undersized rough openings on 1950s-1970s block homes. Jalousie and aluminum single-pane units were framed smaller than modern impact-rated windows need. Forcing a new frame into an undersized opening cracks the block and voids the manufacturer warranty. We reframe properly or we walk away.
- Paint-sealed sashes on Victorian and Craftsman homes. Decades of paint seal original double-hung sashes shut, and forcing them open breaks the meeting rails. A new impact-rated unit with simulated divided lights restores the look without the fight.

FAQs - Impact Windows & Doors in Mount Dora
Yes. If your home is in Mount Dora’s National Register Historic District, the Historic Preservation Board must approve your replacement windows and doors before the city will issue a permit. This review doesn’t exist in Eustis or Tavares. The HPB looks at profile, material, divided-light pattern, and overall compatibility. TruePane handles the submittal for you: we prepare the drawings, attend the review if needed, and get the approval before we move to permitting. A homeowner who tries to skip this step ends up with a permit denial and usually a forfeited deposit. Call (954) 280-4413 and we’ll check your address against the historic district boundary first.
Because the rot is coming from ground fog, not water intrusion from above. Mount Dora sits on a ridge above Lake Dora and the Dora Chain of Lakes, and the persistent humidity envelope from the lake surface drives condensation into the bottom rail of original wood windows on north- and west-facing elevations. Replacing the roof doesn’t fix this. The wood keeps rotting from the inside out. The fix is to rebuild the sill and jamb with treated lumber, flash with tape, and install a unit designed for the microclimate. On a McDonald Street Craftsman, that’s exactly what we did: rebuilt the rotted jambs, flashed correctly, and set impact-rated Marvin units with simulated true divided lights. The rot hasn’t returned. Call (954) 280-4413 for a diagnosis.
Yes. Impact-rated windows from Marvin and PGT come with simulated true divided lights, which reproduce the individual lite pattern of a 1920s double-hung unit while meeting current wind pressure and impact requirements. The key is getting the HPB to sign off on the profile. We specify period-appropriate frames and muntin profiles, submit the drawings, and get approval before the permit. A Craftsman with original divided lights is part of the home’s value, and you don’t have to trade that away for code compliance. Call (954) 280-4413 to see samples.
We reframe the rough opening before we set the new window. Jalousie units from the 1950s and 1960s were framed to a different standard, and many are undersized for modern impact-rated frames. Forcing a new unit into an opening that’s too small cracks the block and voids the manufacturer warranty. When we encounter an undersized opening, we write the reframing into the estimate as a separate line item, with a clear allowance, and we get your written approval before we touch it. There’s no change order buried in the fine print. Call (954) 280-4413 for a free estimate that covers the opening, not just the window.
Yes. Mount Dora sits roughly 184 feet above sea level on a ridge overlooking Lake Dora, and that elevation exposes homes to wind loads that the flat surrounding terrain doesn’t experience. The Florida Building Code sets design pressure requirements based on wind speed maps and exposure categories, and homes on the ridge or near the lake often fall into a higher exposure category. That changes the minimum design pressure rating your windows must meet. We calculate the design pressure for your specific address and elevation, and we quote windows that meet the code, nothing less. Call (954) 280-4413 for an exact quote on your home.
How to Get Impact Windows Approved and Installed in Mount Dora’s Historic District
Here’s the part most contractors won’t tell you, because they don’t know it until they’re in front of the Historic Preservation Board and the deposit is gone. Mount Dora’s National Register Historic District contains one of Central Florida’s densest concentrations of Victorian and early 20th-century wood-frame homes. Any window or door replacement in that district requires HPB approval before the city will issue a permit. The board looks at profile depth, material, divided-light configuration, and overall compatibility with the original building. A contractor who can’t spec simulated true divided lights or doesn’t know the HPB submittal process will lose the job, or worse, leave you with a permit denial and no legal path forward.
We run this process end to end. We measure the openings, photograph the existing units, prepare the HPB submittal with period-appropriate profiles, and get the approval in writing before we pull the permit. On a McDonald Street Craftsman, we replaced paint-sealed original double-hung sashes with impact-rated Marvin units using simulated true divided lights and low-E argon-filled glass. The jambs had rot from lake-driven ground fog, so we rebuilt the sill and jamb with treated lumber, flashed with tape, and secured HPB approval before pulling permits. The owner avoided the fix-and-fail cycle that comes from skipping the microclimate diagnosis. That’s the difference between a window job and a window job done right.
For homeowners outside the historic district, the path is simpler: measure, quote, permit, install. But the same care applies. We measure every opening twice, we write the allowances into the contract for anything we might find behind the drywall or stucco, and any surprise is priced and approved in writing before we touch it. Inspect first, allowances written in, surprises approved in writing. That’s how we’ve worked since 2008, and it’s why Mount Dora homeowners call us back.
