Fast, Reliable Impact Windows & Doors Across Dunedin
If you’re searching for impact windows and doors in Dunedin, the conversation almost always starts the same way: an insurance letter arrived, or a window finally gave out after forty years of salt air. We handle both. TruePane serves Dunedin homeowners with code-compliant impact glazing installations, jalousie-to-impact conversions, and structural reinforcement work that gets past the 4-point inspection the first time. Call us at (954) 280-4413 for a free estimate, and a live person answers, day or night.
We know this city’s housing stock. The bungalows near Edgewater Drive, the cottages off Beltrees Street, the waterfront homes along the Dunedin Causeway corridor. They all share something: wood framing from before 1960, original louver windows, and direct exposure to one of the most aggressive salt-air environments in Pinellas County.
Why TruePane Windows & Doors Is Dunedin’s Preferred Impact Windows & Doors Company
Dunedin homeowners call us because they want the job done right the first time, and our reputation here reflects that. We’ve worked on homes throughout the historic core, from the waterfront streets off St. Joseph Sound to the neighborhoods around Dunedin High School and the Pinellas Trail corridor. Our background-checked, uniformed technicians measure every opening twice and quote manufacturer lines side by side on paper, so you see exactly what you’re buying before any work begins.
This is not a franchise operation. TruePane was founded by second-generation glazier Dale Kessler in 2008, and Dale’s founding rule still governs every install: if the pane is not true, the job is not done. We’ve been serving local communities through that craft tradition since 2008, and every Dunedin job is covered by our Done Right Promise and The Keystone Standard. Both manufacturer warranty layers get registered in writing, with durations stated, before the truck leaves your driveway. No paperwork fights. No arguing.
Response time to Dunedin matters. Dispatch and scheduling are coordinated from our South Florida metro office, but our crews serve Dunedin locally. A live person answers the phone 24 hours a day, 7 days a week. Not a voicemail tree. Not a callback form. When you call with a jalousie window that has finally failed an insurance inspection, you talk to someone who knows Dunedin’s housing stock and can schedule accordingly.
Our Impact Windows & Doors Services in Dunedin
Our Impact Windows & Doors team handles the full scope of coastal-glazing work in Dunedin. These are the services most often requested from this city:
Hurricane Impact Windows
Dunedin sits squarely inside Pinellas County’s coastal wind-load zone, with design speeds near 130 mph at the waterfront. That means impact-rated glazing is not optional on most homes here; it’s required by code and by your insurer. We install fusion-welded impact frames with argon-filled low-E sashes that carry both manufacturer warranty layers in writing and pass the wind-mitigation portion of a 4-point inspection on the first visit.

Impact Sliding Glass Doors
Homes along the Dunedin Causeway and the waterfront streets off Bayshore Boulevard need sliding doors that can hold up to wind-driven debris and salt spray at the same time. We convert older single-pane aluminum sliders to impact-rated units with marine-grade anodized finishes, and we always check the track and sill pan before install. A corroded sill pan will fail a new door within two or three years, and we’d rather fix it now than schedule a callback.

Impact Entry & French Doors
Many Dunedin bungalows have the original wood entry doors or mid-century French doors facing the water. Those doors are beautiful, and they leak air and let in humidity. Our impact entry and French door installs use reinforced frames, stainless hardware, and weatherstripping spec’d for marine environments. The Keystone Standard applies here: both warranty layers registered in writing, durations stated, before we leave the driveway.

Impact Garage Doors
Garage doors are the single largest opening in most Dunedin homes, and a non-impact-rated door is often the first thing flagged on a wind-mitigation inspection. We install impact-rated garage doors with reinforced tracks and bracing systems that meet Pinellas County’s coastal requirements. We also check the header above the opening, because many older Dunedin garages were framed with undersized lumber that needs sistering before a heavier impact door goes in.

Trusted Brands We Service in Dunedin
TruePane is an authorized installer for more than a dozen manufacturer lines, and for Dunedin’s salt-air conditions, we routinely quote CGI, PGT, and ES Windows products. CGI and PGT both produce Florida-focused impact-rated lines that hold up well in direct Gulf exposure. ES Windows offers marine-grade anodized frames that resist the pitting and oxidation we see on standard aluminum after just a few years near the Causeway. We stock common replacement parts for these lines locally, which means faster turnaround when a Dunedin homeowner has a seal failure or a hardware issue. We quote side by side on paper so the choice is yours, not the sales rep’s.
Common Impact Windows & Doors Problems We See in Dunedin Homes
- Jalousie louver windows failing 4-point inspections: Original jalousie louvers are the single most common trigger for insurance policy cancellations in Dunedin. They cannot be secured to resist wind pressure, and insurers in Florida treat them as an automatic failure. Converting them to impact-rated glass is the fix.
- Salt-air corrosion on standard aluminum frames: Homes along the Dunedin Causeway corridor and Edgewater Drive see uncoated aluminum window frames pit and oxidize in as little as three to five years. That corrosion works into the glazing edge and eventually the seal fails, fogging the glass and compromising the unit.
- Undersized headers behind jalousie openings: Many Dunedin bungalows were built with load-bearing headers sized only for lightweight louver units. Modern impact-rated insulated glass weighs three to four times more, and the original header will sag or crack under that load if it’s not reinforced.
- Worn weatherstripping and failed sill pans: Non-marine-spec weatherstripping on door sweeps and sill pans degrades within two to three years in Dunedin’s salt air. Once the sweep fails, water intrudes around the frame, and rot starts in the subfloor. We replace with marine-grade materials on every coastal install.
Pricing for Impact Windows & Doors in Dunedin, FL
Here’s the honest picture for Dunedin pricing, and it’s tied directly to the coastal environment. A standard impact-rated single-hung window replacement in an existing opening typically runs $850 to $1,400 installed. An impact sliding glass door, depending on width and configuration, runs $2,800 to $5,500. Converting a full set of original jalousie windows on a 1940s bungalow, including structural header repairs, commonly lands between $9,500 and $18,000. Impact front entry doors run $2,200 to $4,800 installed. Impact garage doors start around $3,200 and go up with size and reinforcement requirements.
The price gap between a coastal-spec and an inland-spec job in Dunedin is real. Marine-grade anodized finishes, stainless hardware, reinforced headers, and upgraded weatherstripping typically add 12% to 18% to the material cost. But here’s the trade-off: the cheap spec costs more within a decade. Standard aluminum frames near the Causeway fail within five years and need full replacement, not repair. Paying for the coastal spec the first time is the cheaper job. We offer free estimates with line-item quotes and a permanent 5% discount for seniors and veterans. Call (954) 280-4413 for an exact quote.

FAQs - Impact Windows & Doors in Dunedin
Standard uncoated aluminum frames near the Dunedin Causeway typically show visible pitting and oxidation within three to five years, driven by salt-laden air off St. Joseph Sound. That’s up to three times faster than homes just ten miles inland in Largo or Safety Harbor. Once corrosion reaches the glazing edge, the seal fails and the unit fogs or loses its impact rating. Marine-grade anodized frames prevent this. Call (954) 280-4413 to have your existing frames assessed.
Original jalousie windows in Dunedin’s 1920s to 1960s bungalows are lightweight, and the load-bearing headers above them were sized for that weight only. Modern impact-rated insulated glass weighs three to four times more, so the original header must be sistered or replaced with engineered lumber and hot-dip galvanized anchors before the new unit goes in. Skipping that step causes sagging and cracking. On a 1940s bungalow near Edgewater Drive, we sistered new headers into place, flashed the openings, and the homeowner passed their 4-point inspection the next week.
On Dunedin’s waterfront streets, including the Causeway corridor and homes facing St. Joseph Sound, we recommend stainless steel or hot-dip galvanized hardware with marine-grade anodized finishes on door frames. Standard zinc or uncoated aluminum hardware pits within a few years of salt-air exposure, and once the hinges or strike plate corrode, the door binds and the security of the opening is compromised. It’s a practical necessity, not an upgrade.
Impact-rated glazing directly addresses the two most common insurance inspection failures in Dunedin: non-rated openings and jalousie windows. A completed conversion to certified impact windows and doors, with the proper wind-mitigation documentation, typically moves a home from non-compliant to compliant on the 4-point and wind-mitigation portions of the inspection. We provide the manufacturer certification and installation documentation your insurer needs. For an exact assessment of your home’s openings, call (954) 280-4413.
A coastal-spec installation in Dunedin uses marine-grade anodized frames, stainless or hot-dip galvanized hardware, sealed sill pans, and weatherstripping rated for salt-air exposure, while an inland-spec job uses standard aluminum and standard hardware. The coastal spec costs about 12% to 18% more in materials, but it lasts the life of the unit. The inland spec near the Causeway fails at the hardware and frame level within five years, and then the whole opening needs replacement, not repair. The cheap spec costs more within a decade.
