Fast, Reliable Custom Windows & Doors Across Dunedin
Custom window and door work in Dunedin costs more than stock replacements for a reason: virtually every home here sits inside Florida’s Wind-Borne Debris Region, so the opening has to carry an impact rating, not just look good. At TruePane Windows & Doors, we’ve measured, ordered, and set enough custom openings on the street-grid blocks around Edgewater Drive and the Pinellas Trail to know exactly what the Dunedin building department will ask before they sign off. A live person answers when you call (813) 320-9346, and the estimate is free. If the pane is not true, the job is not done – that rule governs every custom unit we set in Dunedin.
Why TruePane Windows & Doors Is Dunedin’s Preferred Custom Windows & Doors Company
We run a second-generation glazier’s shop, not a franchise playbook. Dale Kessler founded TruePane in 2008 on a simple complaint: too many window and door companies in Pinellas County register one warranty layer, leave the other unregistered, and count on the homeowner never checking. Our Custom Windows & Doors team works differently. Before the truck leaves your Dunedin driveway, both manufacturer warranty layers are registered in writing, durations stated, and the workmanship is backed by our 90-Day Done Right Promise. No paperwork fights. No arguing.
Dunedin homeowners tend to keep their houses for twenty, thirty, forty years. So do we. We hire local, train apprentices into journeymen, sponsor county fairs and church roof funds, and act like a company that plans to be in town in thirty years. When you call for a custom window or door estimate in Dunedin, you get a background-checked, uniformed technician who measures every opening twice and quotes manufacturer lines side by side on paper. You see exactly what you’re buying, including the design pressure rating your street requires.
Our Custom Windows & Doors Services in Dunedin
Custom Shape Windows
Arched, radius, trapezoid, eyebrow, circle-top – Dunedin’s 1940s and 1950s bungalows have more odd-shaped openings than tract-built subdivisions ever will. We order from manufacturers that cut true radii, not clipped corners, and we frame every rough opening to the flange width the Florida Building Code requires. On a 1950s CBS bungalow two blocks from Edgewater Drive, our crew pulled out original jalousie windows whose louvered glass had been silicone-caulked for decades and replaced them with fusion-welded impact-rated casement units carrying Simonton StormBreaker Plus. Every rough opening got strapping tape, the sashes were reset square, and the wind-mitigation inspection was scheduled the same week.

Commercial Storefront Glazing
Dunedin’s commercial core along Main Street and Broadway carries a lot of older aluminum storefront that was never rated for the wind loads St. Joseph Sound delivers during hurricane season. We replace it with impact-rated storefront glazing that meets Miami-Dade or Florida Building Code standards, and we pull the permit so the paperwork matches the work. Restaurant owners near the marina know the drill: salt air corrodes the threshold pans and jamb screws, and a fogged storefront unit is losing its argon fill and most of its storm resistance. We replace it correctly the first time.

Curtain Wall Systems
Larger commercial and condo projects in Dunedin need curtain wall systems engineered for a coastal site, not a warehouse in Orlando. We work with manufacturers that publish design pressure ratings and Florida Building Code product approval numbers, and every quote lists the exact rating the building department will verify. For multi-story work, a structural engineer signs off on the anchors and mullions. That’s the difference between a curtain wall that passes inspection in Dunedin and one that gets red-tagged on the first review.

Architectural Grilles & SDLs
The original character of Dunedin’s older homes comes from divided-light windows – and too many replacement jobs strip that character out for a flat, modern pane. Architectural grilles and simulated divided lites (SDLs) let us keep the bungalow look while hitting modern impact and energy ratings. We match the original lite pattern where we can, and we specify the grille-in-glass construction so cleaning stays simple. For homes near downtown Dunedin where the historic character matters as much as the wind rating, this is the standard approach, not an upsell.

Trusted Brands We Service in Dunedin
We’re an authorized installer for more than a dozen manufacturer lines, including Andersen, Pella, Marvin, Milgard, PGT, and CGI, so a custom Dunedin project never gets forced into one brand’s catalog. We quote side by side on paper. For impact-rated custom work near the water, we also run ES Windows where the spec calls for a heavier frame. Dunedin homeowners get real choices with the product approval numbers printed on the quote – not a verbal promise that a unit “should” meet code.
Common Custom Windows & Doors Problems We See in Dunedin Homes
- Frozen aluminum jamb screws from salt air. The same salt-laced breeze off St. Joseph Sound that makes Dunedin pleasant in February pits and freezes original aluminum jamb screws within a few seasons. On west-facing replacements, sash removal without cutting becomes impossible, which is why we plan for frame replacement rather than pretending a sash swap will do.
- Undersized rough openings on jalousie-to-impact retrofits. Older CBS walls were never framed for a modern impact flange. A contractor who doesn’t reframe to the required flange width leaves the opening non-compliant and the house potentially uninsurable. We reframe, flash, and document every opening.
- Fogged seals in non-impact insulated glass near the marina. Seal failure is so common in the blocks around the Dunedin marina that homeowners mistake condensation for a cleaning issue. By the time you notice it, the argon fill is gone and the unit’s storm resistance is compromised. A fogged pane near the water is a replacement item, not a wipe-down.
- Jalousie windows patched with silicone for decades. Contractors working the blocks near Edgewater Drive regularly find jalousie louvered glass that’s been repaired with silicone caulk for years. That red flag shows up in Citizens Property Insurance wind-mitigation inspections and can trigger coverage conditions. Replacing them correctly is a code compliance job and an insurance paperwork job at the same time.
Pricing for Custom Windows & Doors in Dunedin, FL
A custom shape window in Dunedin – arched or radius – typically runs $1,200 to $3,800 per unit, installed, depending on the frame material and whether impact glazing is required, which on virtually every street in the city it is. Architectural grilles and SDLs add roughly $150 to $400 per sash over a standard lite pattern. Oversized glass panels for a sliding door wall or fixed picture window run $2,500 to $7,500, and commercial storefront glazing starts near $90 per square foot for a rated aluminum system. Curtain wall work is quoted per project because the engineering drives the number. Every quote is line-item, fixed, and includes the design pressure rating and product approval number your street needs. Call (813) 320-9346 for a free estimate on your Dunedin job.

FAQs - Custom Windows & Doors in Dunedin
Most of Dunedin sits inside Florida’s Wind-Borne Debris Region, which means the unit must carry a Miami-Dade or Florida Building Code impact rating – not just the lower design pressure ratings allowed in inland Pinellas cities like Palm Harbor or Safety Harbor. The exact design pressure your street requires depends on the exposure category the building department assigns, but any honest Dunedin quote lists it in writing along with the product approval number. Call (813) 320-9346 and we’ll tell you what your block requires.
Technically in some cases you can, but most Dunedin homeowners find the numbers don’t work. Corroded jalousie frames need rebuilding before panels will mount, the panels themselves carry a cost, and the wind-mitigation credit from panels is smaller than from impact-rated replacement units. We’ll quote both routes side by side so you see the difference in black and white. Call (813) 320-9346 for exact numbers on your house.
Yes, and in Dunedin the savings are often larger than inland because the wind-mitigation inspection after impact-window installation carries a bigger premium credit for homes this close to open water. The key is having the documentation done correctly the first time – both warranty layers registered, the wind-mitigation form completed, and the product approval number on file. We schedule that inspection the same week as the install. Call (813) 320-9346 to walk through what your insurer will ask for.
Because the prevailing salt-laden air off St. Joseph Sound hits your west and northwest elevations first. That same salt air pits the aluminum frame, freezes the jamb screws, and eats the threshold pans on door openings. East-facing elevations get a break because the salt settles before it reaches them. When we replace a west-facing custom window in Dunedin, we spec a frame finish and fastener package built for that exposure. Call (813) 320-9346 and we’ll look at your specific elevation.
It’s a seal failure, and near the Dunedin marina it’s common enough that we see it weekly. The argon fill is gone, the insulating value is gone, and if the unit was non-impact rated to begin with, most of its storm resistance went with it. That fog is a replacement item, not a cleaning issue – especially on a door that has to hold back wind-driven rain. Call (813) 320-9346 for a free estimate on the replacement.
