Why Lisbon Homeowners Choose TruePane Windows & Doors
Dale Kessler founded TruePane on a rule that still governs every job: if the pane is not true, the job is not done. That’s not a slogan. It’s the standard our crews carry into homes around Lisbon, from the older streets near Lake Eustis to the rural spread east of town.
We’re a second-generation glazier’s company, not a franchise operation running crews through a playbook written in another state. Every technician is background-checked and uniformed. Every opening gets measured twice. Every manufacturer warranty gets registered in writing before the truck leaves your driveway, and the workmanship carries our Done Right Promise. If it’s not done right, we make it right. No paperwork fights, no fine print that covers neither. We’ve spent years building a reputation that matters to people who call rather than click.
Windows & Doors Services We Offer in Lisbon
Window Installation
We set new-construction and retrofit windows in homes throughout Lisbon, including ranch styles from the 1950s through the 1970s that need careful rough-opening work. Our crews flash every opening for Lake County’s ground-level humidity, not just for rain.
Learn more about our Window Installation in Lisbon.

Door Installation
A door that binds in July is a door that was set out of true, and Lisbon’s wet-dry cycles make that problem worse over time. We install entry doors, French doors, and sliding & patio doors in Lisbon that stay square through every season.

Window Replacement
Most Lisbon replacement jobs involve pulling out original single-pane jalousie or aluminum slider units that have corroded in the humidity. We quote manufacturer lines side by side on paper so you see exactly what you’re buying before you commit.

Impact Windows & Doors
Lisbon sits inland, but Florida Building Code wind-load compliance still applies to replacement windows, and many homeowners assume rural properties are exempt. We install Impact Windows & Doors - Lisbon assemblies from CGI, PGT, and ES Windows that meet code and hold up to Central Florida’s summer storm cycle.

Energy-Efficient Windows
Double-pane low-E glass cuts the heat gain that pushes cooling bills up from June through September. For Lisbon’s older homes with original jalousies, upgrading to Energy-Efficient Windows - Lisbon makes a dramatic difference.

Sliding & Patio Doors
We replace worn sliders with modern units that seal properly against ambient moisture from the lakes. Frames, rollers, and tracks get set true so the door glides instead of grinding.

Glass Railing Systems
For homeowners on Lake County’s waterfront parcels, we install code-compliant Glass Railing Systems in Lisbon that hold up to wet conditions. Measurements are precise and the hardware is corrosion-rated.

Custom Windows & Doors
Odd openings, arch tops, or a specific manufacturer line you want matched. We can order and install custom units sized to the opening, not the opening rebuilt to fit a stock unit.

Neighborhoods We Serve in Lisbon
Our crews work across the Lisbon area of Lake County, including:
- Lake Eustis area and shoreline properties

Why Lisbon’s Climate & Housing Affect Windows & Doors
Lisbon sits in the heart of Lake County, one of the most lake-dense counties in the United States. That’s a point of pride for people who live here, but it creates a specific problem for windows and doors. Ambient moisture from surrounding water bodies means assemblies face near-constant humidity, not just seasonal rain. Wood frames rot faster. Aluminum frames oxidize sooner. Seals delaminate earlier.
Most homes in the Lisbon area were built between the 1950s and 1970s with original single-pane jalousie or aluminum slider windows. Jalousies were popular in mid-century Florida because they ventilate, but they offer almost no insulation or storm resistance. By now, many are still operational but badly corroded, and the rough-opening framing behind them has often been quietly taking on moisture for decades. We open those walls and find what’s there before we quote, so the price you get is the price you pay. No surprise line items when rot shows itself.

FAQs About Windows & Doors in Lisbon
Most Lisbon window replacement jobs run between $550 and $900 per double-pane vinyl window installed, with impact-rated units from $950 to $1,600 depending on size and manufacturer line. Rot repair or rough-opening rebuilds are quoted separately after we open the wall. Call (754) 238-2201 for a free written estimate on your specific openings.
Florida Building Code wind-load compliance applies to replacement windows throughout Lake County, including inland Lisbon. Impact-rated windows from CGI, PGT, or ES Windows also cut noise and seal out the humidity that rots rough-opening framing. Whether you choose impact-rated or standard double-pane depends on your home’s specific wind zone and your budget, and we’ll show you both options side by side on paper.
Jalousie windows were designed for ventilation, not sealing. After 50 to 70 years in Lake County’s humidity, the aluminum frames are usually corroded and the glass slats no longer close tight. Modern replacement windows with proper flashing stop the moisture intrusion that has likely been damaging the rough-opening framing for years. Call (754) 238-2201 and we’ll inspect yours before you commit to anything.
No. We measure every opening twice before we quote, and we account for the rot and frame damage we know is common in Lisbon’s 1950s-1970s ranch homes. If we open a wall and find something unexpected, we stop and put the additional scope in writing before any further work. The Done Right Promise means what it says. Call (754) 238-2201 to schedule a free estimate.
Yes. Rotted door frames are one of the most common things we see in Lisbon, and we rebuild them rather than hiding the rot behind a new door. The repair gets quoted in writing before work begins, and the new assembly is set true so it doesn’t bind in July. Estimates are free.
If your windows fog between the panes, your doors stick in the summer, or you’re tired of drafts and moisture you can’t trace, call TruePane Windows & Doors at (754) 238-2201. A live person answers. We’ll schedule a free estimate, measure twice, and give you a written quote that stands. If the pane is not true, the job is not done.

What Lisbon Customers Say
"Had fog between the panes in four windows. They explained the seals had failed and argon was long gone, replaced the glass units instead of selling me whole windows. Honest outfit."
- Frank D."Impact windows on the whole house. They handled the permit, the inspection, and gave me a folder with every approval number for the insurance company. My windstorm premium dropped enough to notice."
- Bill T."Storm door and a new back entry door. Small job, but they treated it like one that mattered. Screws in the hinges are stainless, the sweep actually seals, and the invoice matched the phone quote to the dollar."
- Vernon H.
