Fast, Reliable Custom Windows & Doors Across Dunedin
Custom windows and doors in Dunedin almost always mean impact-rated custom windows and doors, and that changes the whole job. Dunedin sits on St. Joseph Sound with open Gulf exposure, so any permitted replacement must carry a Florida Product Approval and meet Miami-Dade or ASTM impact standards. If you live in a 1920s Craftsman bungalow, the city’s preservation board also limits the visible frame profile, which rules out most off-the-shelf impact windows from the big-box stores. A custom narrow-profile simulated-divided-lite window solves both requirements at once, and that is exactly the kind of work our Custom Windows & Doors team handles for Dunedin homeowners. Call (754) 238-2201 and we will put a straight answer on what your house actually needs.
Why TruePane Windows & Doors Is Dunedin’s Preferred Custom Windows & Doors Company
TruePane has spent more than years in Florida’s coastal building trades, and we know what salt air does to a window frame on Edgewater Drive. We carry marine-grade aluminum, fiberglass, and vinyl framing as standard practice here, not as a premium upsell, because we have seen untreated aluminum pit and seize at the corner joints within five or six years of a Dunedin install. Our technicians measure every opening twice, quote manufacturer lines side by side on paper, and register both warranty layers in writing before the truck leaves the driveway. That is The Keystone Standard, and it is backed by a Done Right Promise: if it is not done right, we make it right, with no paperwork fights and no arguing.
Dale Kessler founded this company on a simple rule that still sits on the whiteboard: if the pane is not true, the job is not done. Dunedin homeowners who have lived in the same house for twenty years tend to appreciate that. They have been burned once by a contractor who left a fogged seal and a door that binds in July, and they are not looking for the cheapest bid. They call us because a live person answers the phone 24 hours a day, seven days a week, and because our background-checked, uniformed technicians treat their home the way they would treat their own mother’s.
Our Custom Windows & Doors Services in Dunedin
Architectural Grilles & Simulated Divided Lites (SDLs)
Dunedin’s historic district is the reason this service gets used more here than anywhere else in Pinellas County. The preservation board wants the look of a true divided-lite window from the 1930s, the Florida Building Code wants impact-rated monolithic glass, and those two demands do not meet in a standard product. An SDL system puts a permanent grille profile on the interior and exterior surface of an impact-rated insulated glass unit, so you get the period look with a Miami-Dade NOA behind it. We quote these side by side in Andersen, Marvin, PGT, and ES Windows, and we handle the design review paperwork so the board is not the one telling you no at the final inspection.

Custom Shape Windows
Arched transoms, round porthole windows, eyebrow windows over a front door on Beltrees Street, trapezoids that follow a roofline. These are common on Dunedin’s older cottage-style homes, and almost none of them are available impact-rated from a catalog. We template the opening, order the custom shape from a manufacturer line that carries Florida Product Approval, and set it in a frame material that will not corrode in salt fog. Custom shape work takes longer to source, but we handle the permit sequencing so you are not sitting with a boarded opening during the wait.

Oversized Glass Panels
Waterfront homes along Edgewater Drive and the Dunedin Marina often call for floor-to-ceiling glass or a four-panel sliding wall that opens to the water. Oversized impact glass is a real engineering problem, not just a bigger sheet. The larger the panel, the more wind pressure it takes across its face, and the rating has to hold for the specific design pressure that applies to your elevation. We have installed oversized ES Windows and CGI panels in Dunedin homes where the opening is 96 inches or more, and every one of them carries the Miami-Dade NOA documentation the building department wants to see. If the pane is not true, the job is not done, and on a ten-foot glass wall, out of true is visible from the driveway.

Commercial Storefront Glazing
Downtown Dunedin’s storefronts face the same salt fog as the residential streets, plus the added punishment of direct sun on Main Street. We glaze and replace commercial storefront systems with heavy-gauge marine aluminum and impact-rated glass, and we work around business hours so a cafe on Broadway does not lose a lunch service. Curtain wall systems follow the same principle on a larger scale: the frame material and the glazing package have to match the wind-load math for the specific building face, and the weep system has to stay clear in salt air or the seal fails from the inside out.

Trusted Brands We Service in Dunedin
TruePane is an authorized installer for more than a dozen manufacturer lines, including, PGT, and CGI. For Dunedin’s coastal conditions we lean on CGI and ES Windows most often because both carry the Miami-Dade NOA and the marine-grade frame options this city’s salt zone demands. We also regularly specify ECO Window Systems and CWS for homeowners who want a fiberglass frame with a narrow sightline that passes the preservation board’s review. Because we are a factory-authorized installer rather than a broker, warranty claims run through us directly, and we register both warranty layers in writing before the crew packs up.
Common Custom Windows & Doors Problems We See in Dunedin Homes
- Salt-corroded aluminum that seizes shut. On Edgewater Drive near the marina, our crew replaced a seized, salt-corroded aluminum casement with a custom impact-rated fiberglass casement from Andersen. The old sash had fused at the corner joints from salt spray within six years; the new frame carries marine-grade hardware and a Miami-Dade NOA.
- Weep holes blocked by corrosion and sand. The small drainage channels at the bottom of a window frame are the first thing salt air attacks. When they clog, water pools inside the frame, the seal fails, and the homeowner sees fog between the panes a year later.
- Historic board rejection on a recent install. We are called in after a contractor installs an off-the-shelf impact window with a thick, modern frame profile, and the preservation board says no. The fix is a tear-out and a custom SDL unit with a period-appropriate sightline, which costs more than doing it right the first time.
- Wrong frame material for the wind zone. A frame can carry the right design pressure rating and still fail early if it is untreated aluminum in Dunedin’s salt fog. Choosing the right corrosion resistance at the estimate stage is the difference between a ten-year window and a callback in year six.
Pricing for Custom Windows & Doors in Dunedin, FL
A custom impact-rated window in Dunedin typically runs $900 to $1,800 per opening installed, depending on size, shape, and the manufacturer line. Architectural SDL grilles add roughly $150 to $300 per sash, and oversized panels or custom shapes push the per-opening cost toward $2,500 or more. A full-house replacement on a 1920s bungalow in the historic district, where every opening needs custom sourcing and preservation review, usually lands between $18,000 and $32,000. Those are honest Dunedin numbers, not a sales pitch.

FAQs - Custom Windows & Doors in Dunedin
Yes. Dunedin sits entirely inside Florida’s wind-borne debris region, so any permitted window or door replacement must carry a Florida Product Approval and meet Miami-Dade or ASTM impact standards, and the age of the house does not waive that requirement. The historic district adds a second layer: the visible frame profile has to pass design review, which is why an off-the-shelf impact window often gets rejected and a custom narrow-profile SDL is the workable answer. Call (754) 238-2201 and we will tell you exactly which products meet both standards before you spend a dollar.
Keep the Florida Product Approval number, the Miami-Dade NOA documentation, the permit and final inspection record, and the written warranty registration from the manufacturer. Under The Keystone Standard, we register both warranty layers in writing before the truck leaves, and we hand you a copy for your insurance file. If your insurer asks for proof of impact compliance after a storm, that paperwork is the difference between a paid claim and a long argument.
Salt fog from St. Joseph Sound carries chloride that attacks the aluminum at weep holes and corner joints, and the corrosion rate on an untreated standard frame is aggressive enough that sashes seize shut or corners split within five to seven years. That is why we lead every Dunedin estimate with frame material selection rather than glazing package: marine-grade aluminum, fiberglass, or vinyl is a practical necessity here, not an upgrade. Call (754) 238-2201 for a free estimate and we will show you the difference on paper.
Simulated divided lites put a permanent grille profile on both surfaces of the glass, so the window reads as a true divided-lite sash from the sidewalk while the monolithic impact glass behind it carries the required Florida Product Approval. The preservation board gets the period-appropriate sightline it wants, and the building department gets the documented impact rating it requires. A standard big-box impact window with a thick slab frame cannot do both.
You can, and yes, size affects the rating. A larger panel takes more wind pressure across its face, so the design pressure calculation has to work for the specific opening size and elevation, and the manufacturer has to have that size tested and approved. We have installed oversized impact panels up to 96 inches and larger in Dunedin waterfront homes, and every one carries the Miami-Dade NOA documentation. Call (754) 238-2201 to schedule a free estimate and we will measure the opening and run the numbers before you commit.
