Fast, Reliable Impact Windows & Doors Across Longwood
Impact windows and doors in Longwood typically run $1,100-$2,400 per opening installed, and most 1970s ranch homes need between six and fourteen openings upgraded to meet current Florida Building Code wind-load standards. We’re TruePane Windows & Doors, and we serve Longwood homeowners with a second-generation glazier’s approach: measure twice, quote in writing, register both warranty layers, and stand behind the work for 90 days after the truck leaves. Call (754) 238-2201 and a live person answers, 24 hours a day.
Longwood splits into two very different housing worlds. The Historic Village has late-1800s cottages and early-1900s Craftsman homes where a window swap needs a Certificate of Appropriateness before a permit can even be pulled. Two miles away, Sanlando Springs and the Wekiva-area tracts are full of 1970s CBS ranches still carrying original single-pane aluminum sliders. We work both markets, and we know which compliance path applies to your street before we ever set foot on the property.
Why TruePane Windows & Doors Is Longwood’s Preferred Impact Windows & Doors Company
Dale Kessler founded TruePane in 2008 on a rule he keeps on the whiteboard: if the pane is not true, the job is not done. That rule matters in Longwood because the city demands two things most window companies never reconcile. First, the Historic Preservation Board holds replacement windows in the Historic Village to exact lite patterns and profiles. Second, Seminole County wind-load minimums force upgrades on practically every original 1970s opening once a permit is pulled. We handle both without drama.
Our crews are background-checked, uniformed, and local to this market. They know what a failed flashing tape at the bottom corner of a Sanlando Springs jamb looks like, because they see it every week. They know which manufacturer lines survive Longwood’s daily heat-cool cycling without fogging. And they quote every job on paper, side by side, so you see exactly what you’re buying before you sign. No surprises on the bill, no voicemail tree, no second appointment left hanging.
Our Impact Windows & Doors Services in Longwood
We install, replace, and service impact windows and doors across every Longwood neighborhood. Here’s how we approach the work that matters most to homeowners here.
Hurricane Impact Windows
Replacing original aluminum single-pane sliders with impact-rated units is the single biggest retrofits job in Longwood’s 1970s ranch subdivisions. We quote manufacturer lines like PGT, CGI, and CWS side by side on paper, with low-E and argon fill specified in writing. For Historic Village homes, we source impact units that match original lite patterns, because the Preservation Board will reject off-the-shelf double-hungs.

Impact Sliding Glass Doors
Original sliding patio doors on Longwood tract homes often have hollow-core panels, bent tracks, and no reinforcement at the jambs from the 1970s. We replace them with impact-rated sliders that meet Seminole County wind-load requirements, including proper jamb reinforcement. The opening itself is the weak point in most retrofits, and we do not skip that detail.

Impact Entry & French Doors
The 1980s ranch stock in Longwood frequently has steel or fiberglass entry doors that bind in July heat and leak air around the weatherstripping. We install impact entry doors and French doors with proper flashing, sealing, and alignment. If the original frame is rotted from years of afternoon thunderstorm moisture, we repair or replace the jamb before the new door goes in.

Impact Garage Doors
Impact garage doors on older Longwood homes often lack the jamb reinforcement the current code expects. We replace the door and the weak points around it, because a fortified wall means nothing if the garage opening collapses in a wind event. Every opening is re-flashed and sealed to keep Longwood’s humidity out of the framing.
We also handle Impact Windows & Doors work including hurricane shutters and wind mitigation documentation, which we’ll cover below.

Trusted Brands We Service in Longwood
We’re an authorized installer for more than a dozen manufacturer lines, and in Longwood that translates to real availability. We regularly install PGT, CGI, and ES Windows impact units because those lines hold up to Central Florida’s UV intensity without seal failure. We keep common parts for local jobs on hand, so a warranty callback in Longwood does not mean waiting on a freight shipment. When we quote, we show you the manufacturer, the glass package, and the warranty duration on paper before you commit. That’s the Keystone Standard, and it applies on every opening we touch.
Common Impact Windows & Doors Problems We See in Longwood Homes
- Failed flashing tape on 1970s CBS openings. Original installations used thin tape that degrades after forty years of daily heat-cool cycling. Afternoon thunderstorms wick moisture into the jamb and behind the stucco, and by the time a homeowner notices a soft spot near the window, mold is already growing in the framing.
- Fogged argon-filled insulated glass from early 2000s retrofits. Central Florida’s intense UV and temperature swings break the seal on cheaper insulated glass units. The gas leaks out, the glass fogs, and the insulation value drops long before anyone sees condensation on the inside pane.
- Off-the-shelf vinyl double-hungs rejected in the Historic Village. The Historic Preservation Board requires replacement windows to match original lite patterns and profiles. Standard vinyl units do not qualify, and the permit stalls until the right units are specified.
- Unreinforced garage door jambs on ranch homes. Even when the windows and entry doors are impact-rated, the garage opening is frequently left untouched. That opening becomes the failure point in a wind event because the jamb was never reinforced to carry the load.
Pricing for Impact Windows & Doors in Longwood, FL
A typical impact window replacement in Longwood runs $1,100-$2,100 per opening installed, depending on size, manufacturer, and whether the existing frame needs repair. Impact sliding glass doors run $2,800-$5,600 installed. Impact entry doors range from $1,600-$4,200, and impact garage doors start around $2,400 and go up from there based on size and reinforcement scope. Historic Village homes tend toward the higher end because the units must match original profiles, which often means custom sizing and specialty glazing.
What drives cost in Longwood specifically is the condition of the opening once we open it up. A 1974 CBS ranch with failed flashing and moisture-damaged framing will cost more than a clean 1990s retrofit. We write an allowance line item into every contract for framing repair, so that work is priced and approved in writing before we touch the wall, never as a surprise on the final bill. Call (754) 238-2201 for a free estimate. We quote on paper, side by side, with both warranty layers registered before the truck leaves your driveway.

FAQs - Impact Windows & Doors in Longwood
Yes. Any replacement window or door in the Longwood Historic District requires a Certificate of Appropriateness from the city’s Historic Preservation Board before Seminole County will issue a building permit. We handle that paperwork for you and specify impact-rated units that match original lite patterns and profiles, which keeps the permit moving. Call (754) 238-2201 and we’ll tell you if your street falls inside the district.
Once you pull a building permit for the interior remodel, Seminole County will require the windows to meet current wind-load minimums, which original 1970s single-pane aluminum sliders do not. That means the window upgrade becomes part of your permitted scope, not an optional add-on. We write the wind mitigation and glazing work into the allowance line items so the cost is clear before we start.
Longwood’s daily heat-cool cycle breaks the seal on low-cost insulated glass units faster than national averages. The argon gas leaks out, the seal fails, and condensation forms between the panes. We install manufacturer lines like PGT and ES Windows specifically because their seal warranties hold up under Central Florida UV intensity and thermal cycling. Call (754) 238-2201 if your glass is already fogged and we’ll tell you whether it is a warranty replacement or a seal repair.
Yes. We source impact-rated units with custom lite patterns and wood or wood-clad profiles that satisfy the Historic Preservation Board. This is a specialty order, not an off-the-shelf product, but we handle the specification, the paperwork, and the installation so you do not get stalled at the permit stage. The work runs toward the higher end of Longwood pricing because the units are built to match your original openings, not a standard extrusion line.
The first thing we check is the condition of the existing flashing and jamb at each opening. On 1980s CBS construction, failed flashing tape and moisture-wicked framing are common, and that condition drives the real cost of the job. We inspect before we quote, and any framing repair goes into the written allowance line item, so you never get surprised after the wall is open.
Call (754) 238-2201 and ask for a free estimate on your Longwood impact windows and doors. A live person answers, 24 hours a day. Written line-item quotes, both warranty layers registered in writing, and a Done Right Promise on every job we install. No paperwork fights, no arguing. If the pane is not true, the job is not done.
