Fast, Reliable Impact Windows & Doors Across Dunedin
Replacing windows or doors in Dunedin is not the same job it is in Clearwater or Safety Harbor, and any installer who treats it that way is setting you up for a problem. Dunedin sits directly on St. Joseph Sound, which means virtually the entire city falls inside Florida’s wind-borne debris region and every permitted replacement must carry impact-rated glazing. But the city’s stock of 1920s-1950s Craftsman bungalows and its active historic preservation board add a second layer of rules most window companies never think to check. We do. TruePane Windows & Doors serves Dunedin homeowners with Impact Windows & Doors installed to meet both the Florida Building Code and the city’s design-review standards, and we have been doing it long enough to know what hides behind the old jalousies and single-pane sliders this town is full of. Call (754) 238-2201 for a free estimate, and we will walk the job with you before anyone touches a wall.
Why TruePane Windows & Doors Is Dunedin’s Preferred Impact Windows & Doors Company
We are not a franchise operation that drops a different crew in Dunedin every week. TruePane was founded by second-generation glazier Dale Kessler, and the rule that names the company is the rule that governs every install: if the pane is not true, the job is not done. Dunedin homeowners call us because we answer the phone with a live person, we show up when we say we will, and we write both warranty layers into the contract before the truck leaves the driveway. That is The Keystone Standard, and it means every manufacturer warranty gets registered in writing, with durations stated, on the day of the install. Our Done Right Promise backs the workmanship. If something is not right, we make it right. No paperwork fights, no arguing.
We know Dunedin’s housing stock, and that matters more here than in most Pinellas County cities. The historic district off Main Street, the cottage rows near Edgewater Drive, the mid-century blocks east toward Belcher Road, and the waterfront corridors along Bayshore Boulevard all carry different frame profiles, different opening conditions, and different design-review exposure. Our background-checked, uniformed technicians measure every opening twice and quote manufacturer lines side by side on paper, so you see exactly what you are buying. We are an authorized installer for more than a dozen lines, including PGT, CGI, and we stock parts for the brands Dunedin homes already have. Dispatch is coordinated from our South Florida office, but the crews that serve Dunedin work locally and know the territory.
Dale Kessler built TruePane on years of community service and a simple stance: a square deal, written down, backed up. We offer a permanent 5% discount for seniors and veterans, and our standing offers include a free written repair estimate and a maintenance check. Those are not gimmicks. They are part of how we treat the people who call.
Our Impact Windows & Doors Services in Dunedin
Hurricane Impact Windows
Most Dunedin homes we visit still have at least a few original jalousie louvered windows or early single-pane aluminum sliders. Neither has any hurricane resistance, and both perform terribly on energy efficiency. We replace them with impact-rated windows sized to the existing openings where we can, and re-framed properly where we must. In Dunedin’s historic district, that often means sourcing narrow-profile, simulated-divided-lite impact frames that satisfy the preservation board and the Florida Building Code at the same time. A typical full-home impact window replacement on a 1,200-1,600 square foot Dunedin bungalow runs $14,000-$24,000 depending on frame material, glazing package, and how many openings need structural correction.

Impact Sliding Glass Doors
Sliders are the weak point on almost every pre-1960 cottage in Dunedin. The original tracks are worn, the rollers are shot, and the aluminum frames often show salt corrosion at the weep holes and corner joints. We install our Sliding & Patio Doors in Dunedin with impact-rated glass and marine-grade aluminum or vinyl framing, set square and flashed correctly for Gulf air exposure. If the rough opening has drifted or the header is undersized, which we find often on older wood-framed homes, we correct that before the new unit goes in. A replacement impact slider for a standard 72-inch opening in Dunedin typically runs $3,800-$7,500 installed, depending on the glazing package and whether the opening needs re-framing.

Impact Entry & French Doors
Front doors and Custom Windows & Doors in Dunedin like patio French doors take direct salt air, and standard steel or builder-grade aluminum frames corrode faster here than they do ten miles inland toward Tampa. We install impact-rated entry doors and French doors with frames built for marine exposure, weatherstripping that holds up, and hardware that will not seize in the humid season. Historic bungalows near the Dunedin Marina sometimes require custom casing profiles to pass design review, and we handle that matching in-house. A single impact entry door replacement in Dunedin runs $2,800-$6,200; a French door set runs $5,500-$11,000, depending on size, swing configuration, and frame material.

Impact Garage Doors
Garage door openings are the single largest unsupported span in most Dunedin homes, and a non-rated door in a wind-borne debris region is a structural liability. We replace standard garage doors with impact-rated models, and we check the track attachment and header condition before we hang anything. Many pre-1960 Dunedin garages were built with undersized headers, and a code-triggering replacement means that has to be addressed. A single-car impact garage door replacement in Dunedin runs $2,400-$4,800; a double-car door runs $3,800-$7,200, including a full track and hardware swap.

Trusted Brands We Service in Dunedin
We are an authorized installer for more than a dozen manufacturer lines, including , and for the salt-air environment we regularly specify PGT, CGI, ES Windows, and ECO Window Systems. These brands offer marine-grade frame options and impact glazing packages that hold up on the west side of the Florida peninsula, which is a different durability test than the inland market. We keep parts in stock for the brands already on Dunedin homes, and we quote side by side on paper so you can compare frame materials, glazing packages, and warranty terms without guessing. If you have an existing brand you like, we service it, and if you want a recommendation for a Dunedin historic bungalow, we will tell you exactly what we would put on our own house.
Common Impact Windows & Doors Problems We See in Dunedin Homes
- Salt-corroded aluminum frames that seize shut or separate at the corners. Standard aluminum window frames and door hardware on Dunedin’s Gulf-air streets begin pitting at weep holes and corner joints within five to seven years. We replace them with marine-grade aluminum, vinyl, or fiberglass framing that is not optional here, it is the bare minimum for longevity.
- Undersized or out-of-square rough openings in older wood-framed homes. Pre-1960 bungalows and cottages were not built to the tolerances modern impact units require. When a permit triggers, we routinely find headers that have to be corrected and openings drifted out of square by half an inch or more, and that work has to be done before the new window or door can be set true.
- Historic district design rules that reject standard replacement profiles. Dunedin’s preservation standards do not allow a lot of modern replacement window profiles, which means homeowners who bought windows from an installer that did not pre-check the guidelines end up with units they cannot legally install. We check design-review requirements before we order anything, and we source simulated-divided-lite impact frames that pass the first time.
- Salt-driven rot behind original jalousie windows. Jalousie louvered windows leak, and on Dunedin’s west side that leakage carries salt into the wall cavity. We regularly find early rot at the king studs and sill plates behind what looks like a perfectly fine jalousie on the interior. If we do not fix that when the walls are open, the new window is sitting on compromised framing.
Pricing for Impact Windows & Doors in Dunedin, FL
Here is what you should expect to pay for impact work in Dunedin, based on current market pricing and the scope of most homes we see in the city: impact window replacements on a bungalow run $14,000-$24,000 for a full house. Individual impact windows for standard openings run $900-$1,800 per unit, and custom simulated-divided-lite units for historic district homes run $1,400-$2,600 per unit. Impact sliding glass doors land at $3,800-$7,500. Impact entry doors run $2,800-$6,200. Impact garage doors run $2,400-$7,200 depending on size. What moves the number on a Dunedin job is frame material (marine-grade costs more and is worth it), the amount of structural correction the openings need, and whether design review requires custom profiles. We give you a written line-item quote before work starts, and we never change the price once the job is approved unless you approve a change in writing first.

FAQs - Impact Windows & Doors in Dunedin
Any permitted window or door replacement in Dunedin must carry impact-rated glazing or an approved shutter system, because the city sits inside Florida’s wind-borne debris region. That applies whether the home is a 1925 bungalow or a 2005 block home. If you are replacing a window or door under permit, the new unit has to meet the current Florida Building Code for wind resistance, which means impact-rated or protected by an approved system. Call (754) 238-2201 and we will tell you exactly what applies to your street and your opening.
Not always. Dunedin’s historic preservation board restricts visible exterior alterations, and many standard double-hung replacement profiles do not pass design review because the frame width, muntin profile, or exterior trim look wrong on a 1920s-1950s bungalow. You will typically need narrow-profile, simulated-divided-lite impact frames, and we source those regularly for homes near Edgewater Drive, Main Street, and the historic core. We check design-review requirements before we order, so you do not end up with windows you cannot legally install.
Dunedin sits directly on St. Joseph Sound with open Gulf exposure, so salt-laden air reaches even inland residential streets, and standard aluminum frames start pitting at weep holes and corner joints within five to seven years. Clearwater’s eastern neighborhoods are buffered, but Dunedin takes the salt straight. That is why we lead every estimate in Dunedin with frame material selection, not glazing. Marine-grade aluminum, vinyl, or fiberglass is a practical necessity here, not an upsell. Call (754) 238-2201 and we will show you the difference in person.
We stop and tell you, in writing, with photos, before we do anything else. On a 1947 cottage near Edgewater Drive, our crew pulled a seized original jalousie and found the rough opening had drifted out of square by nearly 3/4 inch and the king studs showed early salt-driven rot. We re-framed to true, flashed the opening with butyl tape, and set a ViewLux casement with impact-rated glazing and marine-grade aluminum, then re-trimmed the interior to match the home’s original casing profile so the historic review passed on the first submittal. We also install our Glass Railing Systems in Dunedin for homes needing modern safety features that complement historic design. That is the standard. If we find rot or undersized headers on your Dunedin home, we price the correction in writing and get your approval before we touch it. No change orders that show up as a surprise on the final bill.
Yes, and the difference in Dunedin is more pronounced than you might expect because many local homes still have original jalousie louvered windows, which leak conditioned air constantly. Impact-rated windows with low-E glazing stop that leakage, reduce UV damage to floors and furnishings, and cut the load on your AC through the long humid season. Most Dunedin homeowners see a measurable drop in their FPL bill, and the structural and noise benefits come on top of that. Get an estimate before you decide the math does not work: call (754) 238-2201 and we will walk you through the real numbers for your house.
