We fix those problems and replace what cannot be fixed. TruePane Windows & Doors serves Fern Park residents with a live person on the phone at (754) 238-2201 whenever you call, and technicians who know the local housing stock well enough to quote the job correctly the first time.

Why Fern Park Homeowners Choose TruePane Windows & Doors
Dale Kessler founded TruePane in 2008 as a second-generation glazier, but the practice behind it runs deeper than that: measure every opening twice, quote manufacturer lines side by side on paper, register both warranty layers in writing before the truck leaves the driveway. We operate by a rule that has not changed since the first pane was set: if the pane is not true, the job is not done.
Homeowners in the Fern Park area call us because the work holds up. We have replaced jalousie windows in the neighborhoods along Prairie Lake and repaired sliding glass doors on homes east of US-17-92 that other companies said could not be repaired. Technicians arrive background-checked and uniformed, and they work in your home the way they would work in their own mother’s. When the job is finished, you get the Done Right Promise and The Keystone Standard, our practice of putting both manufacturer warranty layers in writing with durations stated. No paperwork fights, no argument about who covers what.
We are an authorized installer for more than a dozen manufacturer lines, including, PGT, and CGI. That matters in Fern Park because many local homes need custom-sized units. Having access to multiple lines means we can quote you three or four viable options for a non-standard opening instead of telling you one is your only choice.
Windows & Doors Services We Offer in Fern Park
Window Installation
New window installation in Fern Park often means full-frame replacement when the original single-pane aluminum frames have oxidized beyond salvage. We measure every opening twice, confirm rough-opening dimensions against the manufacturer’s cut sheet, and set the unit square, level, and plumb.
Learn more about our Window Installation in Fern Park.

Door Installation
Front doors, side doors, and Florida room doors in Fern Park’s ranch homes are frequently hollow-core steel or louvered wood units that have been swelling and sticking for decades. We install pre-hung exterior doors with proper flashing and threshold sealing that holds against wind-driven summer rain.

Window Replacement
Replacement work dominates our schedule in Fern Park because the original aluminum single-pane windows and jalousie units in 1950s through 1970s concrete-block homes have reached the end of their service life. We handle full-frame replacement, custom sizing for non-standard block openings, and energy-code compliance under Florida’s current Title 11 requirements.

Impact Windows & Doors
Fern Park sits inland in a lower wind-speed design zone than coastal Seminole County, but impact-rated products still matter for storm season and insurance savings. We install impact windows and doors from PGT, CGI, and ES Windows, with product approvals documented and both warranty layers registered.

Energy-Efficient Windows
When your air conditioning runs more than ten months a year, the thermal performance of your windows is not a luxury. In Fern Park, original single-pane aluminum windows are the weakest thermal link in most homes, and upgrading to insulated low-E glass units with vinyl or thermally broken frames reduces cooling load and interior condensation the first summer.

Sliding & Patio Doors
Sliding glass doors on older Fern Park homes often have rollers that were last touched during the Reagan administration. We replace worn track systems, realign doors that drag, and install new sliding and patio doors when the frame itself has rusted or warped beyond repair.

Glass Railing Systems
For elevated decks, patios, and pool enclosures, frameless and semi-frameless glass railing systems provide a clean sight line and code-compliant safety. We install tempered glass railing panels with corrosion-resistant hardware suited to Florida humidity.

Custom Windows & Doors
Concrete-block construction means non-standard rough openings are common in Fern Park, particularly in screened Florida rooms built as DIY additions over original jalousie frames. We order custom-sized windows and doors from multiple manufacturers and coordinate masonry work when an opening needs minor modification.

Neighborhoods We Serve in Fern Park
Our technicians work throughout Fern Park and know the difference between a block home near the Prairie Lake chain and a frame-built addition that shifted over the years. Typical response time for an estimate in the Fern Park area is same-day or next-day scheduling once you call.

Why Fern Park’s Climate & Housing Affect Windows & Doors
Fern Park is an unincorporated enclave of Seminole County tucked along the US-17-92 corridor, which means every window and door permit routes through Seminole County’s building department rather than a city hall. That distinction catches contractors who do most of their work in neighboring Casselberry or Altamonte Springs and assume a city permit office handles it. We pull county permits before work starts and coordinate inspections so the job closes clean.
The housing stock here is dominated by modest concrete-block ranch homes built between roughly 1955 and 1975. Many still carry their original aluminum single-pane windows, jalousie units in the Florida room, and hollow-core steel or louvered wood exterior doors. Because the walls are concrete block, window openings frequently measure out at non-standard dimensions, which means off-the-shelf inserts from a big-box store usually will not fit properly. We order custom-sized units and, where necessary, handle the small masonry modifications that make a full-frame replacement sit right in a block opening.
Humidity routinely runs above 75 percent in Fern Park, and the near-daily summer thunderstorms drive rain against aging perimeter sealant until it fails. Failed sealant on an old flanged window shows up fast: water stains on interior drywall, soft wood sills, and condensation between panes that will not dry. Aluminum frame oxidation from constant humidity is another common call. These are not maintenance issues you can caulk your way out of for another season.

FAQs About Windows & Doors in Fern Park
Full-frame window replacement in Fern Park typically runs $800 to $1,800 per opening because most local homes are concrete-block construction with non-standard rough openings that require custom-sized units rather than off-the-shelf inserts. Jalousie or single aluminum pane glass-only replacement runs $150 to $400 when the frame is still sound. Get an exact number with a free estimate: call (754) 238-2201.
Yes. Fern Park is unincorporated Seminole County, so permits route through the county building department rather than a city hall. We pull all required permits before work begins and coordinate inspections so the job closes without you chasing paperwork.
Yes, and this is one of the most common jobs we handle in Fern Park. The screened Florida rooms added to 1960s ranch homes were often DIY enclosures built over jalousie windows whose rough openings match no modern standard size. We order custom units from multiple manufacturers and handle the masonry adjustments needed to make the new window square and sealed. Call (754) 238-2201 for a quote that accounts for the custom sizing from the start.
If the glass is fogged between panes, the frame is oxidized or warped, or sealant failure has caused water intrusion through the wall, replacement is usually the better call. If the frame is sound and only the glass or hardware is bad, repair usually makes more sense. We will tell you which applies to your home, and we will quote both options when either is viable.
No. The number on your written estimate is the number on the final bill. If we find something unexpected behind the stucco or drywall once we open the wall, we stop, photograph it, and give you a written change order before proceeding. You approve the extra work or you do not. There is no surprise line item at the end.

What Fern Park Customers Say
"Our bay window had rotted at the sill and two other outfits wanted to talk us into a flat picture window instead. TruePane rebuilt the opening and matched the original look. Neighbors have knocked on the door about it."
- Gene A."French doors to the patio, custom size because this house was built in 1961 and nothing is standard. Measured twice, three weeks to fabricate like they warned, and the install day they laid runners over my floors without being asked."
- Marie S."A casement crank had stripped and the sash was swollen shut. The technician, Ray, fixed the crank on the spot and only then talked about replacement for the three windows that were genuinely done. That is why the whole street uses them now."
- Eleanor G.
