If you live in Lake County, you already know the humidity does things to window frames and door jambs that drier parts of Florida never experience. Fogged glass, swollen wood, failing seals on aluminum sliders. TruePane has seen all of it, and we fix it the way it should have been built in the first place. Our Custom Windows & Doors team measures every opening twice, quotes manufacturer lines side by side on paper, and registers both warranty layers before the truck leaves your driveway.
We are not the cheapest bid you will get, and we won’t pretend otherwise. We are the last call you’ll need to make on a window or door.
Why TruePane Windows & Doors Is Lisbon’s Preferred Custom Windows & Doors Company
Dale Kessler founded TruePane in 2008 on a rule that names the company: if the pane is not true, the job is not done. He is a second-generation glazier, not a franchise operator, and that matters when you’re spending five figures on windows that need to outlast the mortgage. Our crews are background-checked and uniformed, and they work in your home the way they’d work in their own mother’s.
Lisbon customers get a company that thinks about Lake County conditions before it thinks about anything else. We know the difference between surface condensation on a humid morning and a failed insulated glass unit. We know which manufacturer lines hold up near lake water and which ones don’t. And we know that when you call, you want a person, not a call tree. A live person answers every call, 24 hours a day, 7 days a week. Not a voicemail box. Not a regional call center. A person who knows windows.
Every job is covered by the Done Right Promise and The Keystone Standard: both manufacturer warranty layers registered in writing, durations stated, before our truck pulls away. If something isn’t right within 90 days, we make it right. No paperwork fights. No arguing. No fine print that covers neither.
Dispatch and scheduling are coordinated from our South Florida office; crews serve Lisbon locally and know the roads, the building stock, and the county permitting desk well enough to keep a project moving.
Our Custom Windows & Doors Services in Lisbon
We install, replace, and service custom windows and doors for residential homeowners throughout Lisbon. Here is what that looks like in practice.
Custom Shape Windows
A round-top window above a front door, a trapezoid pane under a gable, an arched transom on a 1970s ranch. These are not stock items. We measure, order, and install custom shape windows built to the exact opening, with framing that matches your existing envelope and glass packages dialed for Lake County humidity. If the opening was cut wrong in 1972, we address that before the new unit goes in, rather than forcing a square peg into an out-of-round hole.

Commercial Storefront Glazing
We work with small commercial properties in and around Lisbon, including storefronts with aluminum framing that has sagged, fogged, or lost its seal. A storefront with a fogged pane tells every customer who walks past that the owner doesn’t sweat the details. We replace the glass, rebuild the framing where it’s needed, and leave the storefront looking the way it did when it was new, at a price that doesn’t require a board vote.

Curtain Wall Systems
For the few commercial and larger residential builds in the Lisbon and Lake County area that use curtain wall, we plan, supply, and install the system. These are not forgiving installations: a curtain wall that isn’t square at the sill shows up as stress cracks in the glass within a season or two. Dale has been setting glass long enough to know that the first hour of layout determines whether the wall will hold true for twenty years or bind in July.

Architectural Grilles & SDLs
Simulated divided lites (SDLs) and architectural grilles give a window the look of true divided light without the thermal penalty of old single-pane construction. We spec and install SDLs that match the architecture of your home, whether it’s a mid-century ranch off Goose Prairie Road or a lakefront place with a porch that gets hammered by afternoon sun. The grilles are applied to the interior and exterior surfaces, or installed between the glass, depending on the manufacturer line and the look you want.
Our work in Lisbon on custom windows and doors often pivots on a detail contractors from drier markets miss: the ambient humidity around Lake County’s inland lakes means your glass packages need low-E coatings and argon fill that holds up, and your framing needs flashing details that don’t rely on caulk doing the waterproofing by itself. We build for this climate, because we work in it every week.

Trusted Brands We Service in Lisbon
TruePane is an authorized installer for more than a dozen manufacturer lines, including, PGT, CGI, and ES Windows. For custom work in Lisbon, we often draw on CGI and CWS for their inland wind-rated product approvals that meet Lake County code without the coastal price premium, and we use ES Windows for oversized glass panels and custom shape work. We quote manufacturer lines side by side on paper, so you see exactly what you are buying before you sign anything. When a part or replacement unit is needed, we work directly with the manufacturer’s local distribution, which keeps turnaround tighter than if a general contractor had to source it third-hand.
Common Custom Windows & Doors Problems We See in Lisbon Homes
Lisbon is small and rural. Much of the housing stock dates to the 1960s through the 1980s, and that age shows up in predictable ways. Here are the four most common conditions we walk into:
- Fogged dual-pane glass from failed insulated glass units. Lake humidity works on the seal every summer. Once the desiccant inside the spacer is saturated, the pane fogs. You can’t wipe it off, because the moisture is between the glass. The fix is a new IGU or a new unit, not a cleaning.
- Original jalousie windows and single-pane aluminum sliders. These were cost-effective in 1974. They leak air, transmit heat, and make your central AC run hard from May through October. Replacing them with code-compliant low-E double-hung or casement units drops the energy bill and changes the street appearance in one shot.
- Rotted wood door jambs and sill pans. Lake County rain runs harder than most people think. When an original louvered wood door loses its sill seal, water sits in the jamb, and the rot starts. By the time you see it, the bottom 18 inches of the jamb is usually gone. We cut out the rot, set the new unit with proper flashing tape, and repaint the jamb so the repair blends.
- Water intrusion at party walls on tightly spaced lots. When two homes sit close, flashing details at the wall line matter more. If a neighbor’s roofline directs rainwater into the space between houses, your door or window jamb becomes the drain. We fix the opening and, where possible, adjust the flashing to redirect water away from the structure.
Pricing for Custom Windows & Doors in Lisbon, FL
Custom shape windows in Lisbon typically run $1,200 to $4,500 per opening. Architectural grilles and SDLs add $90 to $250 per sash depending on the pattern and the glass package. Oversized glass panels, the kind used for a lake-facing gable or a modern great-room wall, start around $1,800 and run up to $6,500 depending on the size, the required wind-load rating, and whether tempered or laminated glass is needed. Commercial storefront glazing work runs $75 to $180 per square foot for new aluminum framing and glass, with curtain wall systems quoted on a project basis.
What moves the price is the opening size, the glass package, the frame material, and whether the existing rough opening needs structural repair. In Lake County, the wind-load calculation matters: Lisbon sits outside the High-Velocity Hurricane Zone, so we spec to inland thresholds rather than coastal HVHZ. That runs $20 to $40 per square foot less than a quote from a contractor who specs coastal-rated product as a matter of habit. You should not pay for a category you are not in.

FAQs - Custom Windows & Doors in Lisbon
No. Lisbon sits in Lake County, which is outside Florida’s High-Velocity Hurricane Zone. Your windows and doors must meet Lake County’s inland wind-speed product approval thresholds, not the stricter Miami-Dade HVHZ ratings. This routinely saves Lisbon homeowners 15 to 30 percent versus quotes from coastal or Orlando contractors who spec HVHZ-rated product out of habit. Call (954) 280-4413 and we’ll show you the code requirement in writing before we quote you.
It shortens it, measurably. An insulated glass unit that might last 22 to 25 years in a dry inland market often fails in 14 to 18 years around Lisbon’s lakes, because persistent ambient humidity loads the edge seal every summer. Once the seal fails, the pane fogs between the glass and the IGU is done. We spec low-E coatings with a desiccant matrix suited to wet climates, and we register both warranty layers so the date and duration are documented in writing, not left to someone’s memory.
You can, but you usually shouldn’t. Jalousie frames are single-pane by design: they are a series of glass slats in a metal channel, with no thermal break and no sealed airspace. Replacing just the glass leaves you with the same air leakage and the same heat transfer. The better move in most Lisbon homes is a full-unit replacement with a modern double-hung or casement that fits the original rough opening, meets current code, and drops your cooling load. We’ll show you both options and the price difference on paper.
Because that contractor either didn’t know Lake County’s inland wind-load requirements or quoted a coastal product out of convenience. Some contractors keep one product line and one spec on the truck. Lisbon does not require HVHZ-rated windows or doors. You are being quoted a category you don’t need, and the upcharge is real. A correct Lake County quote uses inland wind-speed product approval. That single distinction is worth hundreds to thousands of dollars on a whole-house window package. It’s also exactly the kind of thing we check before we write the estimate.
It can, depending on the panel size and the structural header above the opening. Any opening wider than 6 feet typically requires a structural header evaluation and a county permit. Lake County reviews the wind-load calculation and the glass thickness spec before the panel is ordered. We pull the permit, submit the engineering, and pass the inspection before we call the job done. That’s standard practice on our jobs, not an upgrade line item.
