Why Largo Homeowners Choose TruePane Windows & Doors
Most of our Largo customers have owned their homes for twenty years or more. They’ve dealt with the door that binds in August, the window seal that fogged over after a storm, the installer who never called back. They’re done with that. We’re a second-generation glazier’s shop, founded by Dale Kessler on a rule that’s still on the whiteboard: if the pane is not true, the job is not done.
We’ve worked throughout Largo, from the established streets of Harbor Hills to the retirement communities along East Bay Drive. Our technicians are background-checked and uniformed. They measure every opening twice, quote manufacturer lines side by side on paper, and don’t leave until both warranty layers are registered in writing. That’s The Keystone Standard, and it’s on every job we do. If something isn’t right within 90 days, we make it right. No paperwork fights, no arguing.
We’ve been serving communities since 2008, and we hire local, train apprentices into journeymen, and plan to be in Largo thirty years from now. A live person answers our phone 24 hours a day, 7 days a week.
Windows & Doors Services We Offer in Largo
Window Installation
New window installation in Largo means working with CBS concrete block walls, not wood framing. That requires masonry anchors and often custom-fabricated bucks, which is standard practice for our crews. Learn more about our Window Installation in Largo.
Door Installation
Exterior doors in Largo take a beating from Gulf salt air, which corrodes hardware and weatherstripping faster than inland homeowners expect. We install doors with marine-grade hardware specified for this climate. Learn more about our Door Installation in Largo.
Window Replacement
Replacing original jalousie windows into existing CBS rough openings often means cutting and patching block to hit modern standard sizes. It’s a masonry skill set that separates experienced Largo installers from cut-rate crews. Learn more about our Window Replacement in Largo.
Impact Windows & Doors
Largo sits fully within Florida’s Wind-Borne Debris Region, with design wind speeds near 150 mph. Every Impact Windows & Doors in Largo we install carries Florida Product Approval, which is non-negotiable here. We’re an authorized installer for PGT and CGI, among others.
Energy-Efficient Windows
Older Largo ranch homes lose a lot of cooling through single-pane glass and leaky jalousie louvers. We install Energy-Efficient Windows in Largo with low-E insulated units sized properly for masonry openings, which means your AC stops running overtime in August.
Sliding & Patio Doors
Salt air is hard on sliding door tracks and rollers. We replace tired sliders with Sliding & Patio Doors - Largo built for coastal exposure, and we can match the opening to modern code without rebuilding the wall.
Glass Railing Systems
For Largo homes with elevated decks or pool areas, Glass Railing Systems - Largo hold up to coastal weather and give you an unobstructed view. We fabricate to exact field measurements.
Custom Windows & Doors
Not every opening in a 1960s CBS ranch matches a stock size. We handle fully custom windows and doors, built to the measurements we take on site, not the ones a manufacturer assumes.
Neighborhoods We Serve in Largo
Our crews work throughout Largo regularly. Typical response time across the city is one business day for scheduling, with most jobs completed in a single visit.

Why Largo’s Climate & Housing Affect Windows & Doors
Largo’s building boom from the 1950s through the 1970s left a dense stock of concrete block ranch homes, many of them still fitted with the original jalousie windows. Those louvered-glass units offer almost no wind or water resistance, and Florida property insurers, including Citizens, now actively penalize or refuse to cover homes that still have them. If you’ve received a non-renewal letter citing your windows, you’re part of a wave of Largo homeowners facing the same forced replacement cycle. This isn’t a typical upgrade market. It’s an insurance-driven one.
Then there’s the location. Largo sits on the Pinellas Peninsula, roughly five to seven miles from the Gulf of Mexico. That puts the entire city inside Florida’s Wind-Borne Debris Region, with ultimate design wind speeds near 150 mph. Every window and door installed here must carry Florida Product Approval. And the persistent Gulf salt air accelerates oxidation on aluminum frames, corrodes door hardware, and eats weatherstripping faster than homeowners expect. Products not specified for marine-grade exposure will fail early in Largo.
Pricing for Windows & Doors in Largo
Nobody can quote Largo window replacement honestly without seeing the opening. CBS masonry work adds labor that wood-frame markets don’t have, and jalousie-to-standard-size conversions often involve cutting block. That said, here’s what Largo homeowners typically see:
Impact-rated window replacement runs roughly $900 to $1,800 per opening, depending on size and whether block work is needed. Entry door replacement starts around $1,500 and goes up with impact glazing and hardware grade. Sliding glass doors typically fall between $2,500 and $5,000. These are honest ranges, not website bait. We quote manufacturer lines side by side on paper so you see exactly what you’re buying, and there are no surprise line items on the bill. Seniors and veterans get a permanent 5% discount, and we offer a free written repair estimate and a maintenance check.

FAQs About Windows & Doors in Largo
Replacing jalousie windows in Largo typically costs between $900 and $1,800 per opening, depending on whether the existing CBS masonry opening needs cutting and patching to fit a modern standard size. Jalousie-to-impact conversions run higher than simple retrofits because of the block work involved. Call (813) 320-9346 for an exact quote, estimates are free.
Most window replacements in Largo are completed in a single visit, including the unit swap, trim, and warranty registration. The exception is custom-fabricated units or jobs requiring significant masonry work, which may need a second trip. We’ll tell you before we start, not after.
No. We quote upfront and stand behind it. The only time a number changes is if you ask for something different than what was quoted, and we’ll put that change in writing before proceeding. That’s our square deal.
Yes. Pinellas County requires permits for window and door replacement, and we handle the entire permitting process for Largo jobs. We also ensure every unit meets Florida Product Approval requirements before it goes in the opening.
A standard window or door replacement in Largo takes one day for a typical opening. Full-house window replacements run three to five days depending on the number of openings and how much masonry work is involved. We’ll give you a written schedule before we begin.

What Largo Customers Say
"French doors to the patio, custom size because this house was built in 1961 and nothing is standard. Measured twice, three weeks to fabricate like they warned, and the install day they laid runners over my floors without being asked."
- Marie S."A casement crank had stripped and the sash was swollen shut. The technician, Ray, fixed the crank on the spot and only then talked about replacement for the three windows that were genuinely done. That is why the whole street uses them now."
- Eleanor G."Eleven windows replaced in two days. The crew chief, Marcus, showed me the level on every single frame before they caulked it. My wife noticed the street noise was gone before I did."
- Ronald P.
