Window Replacement in Largo - Free In-Home Measure, Written Price

Fast, Reliable Window Replacement Across Largo

Window replacement in Largo comes with specific challenges most Florida contractors never learn to handle correctly, and that’s exactly why we built our Largo service around the city’s dominant housing stock: 1950s through 1970s concrete-block ranch homes. Many still have their original jalousie windows, and if you’ve received a non-renewal letter from Citizens Insurance or a private carrier citing those louvered-glass units, you already know the urgency. We know the masonry work these replacements require because we do it regularly across Largo. Our window replacement crews understand CBS construction, wind-load code, and the salt air that corrodes aluminum frames within a few seasons.

Dispatch and scheduling for Largo are coordinated from our South Florida office, but the crews who show up at your door are local, background-checked, and in uniform. We don’t use subcontractors. We don’t send a salesperson who disappears after the contract is signed. The same technicians who measure your openings are the ones who set the windows and flash the sills.

Why TruePane Windows & Doors Is Largo’s Window Replacement Company

TruePane was founded in 2008 by Dale Kessler, a second-generation glazier, and has built a reputation across Largo for doing the unglamorous work right: cutting block, patching masonry, and flashing openings so they don’t leak in August thunderstorms. Our Largo customers regularly tell us the same thing: they called us because they’d watched too many neighbors deal with windows that fogged, frames that corroded, and installers who vanished when the warranty question came up. We register both manufacturer warranty layers in writing before the truck leaves your driveway. That’s The Keystone Standard, and we don’t make exceptions.

The 90-Day Done Right Promise means what it says. If something isn’t done right, we make it right. No paperwork fights. No arguing. The promise is in writing, and we put it in writing on every Largo estimate.

Dale Kessler’s rule has never changed: if the pane is not true, the job is not done. That governs every install our crews complete in Largo, from a single insert replacement in a Seminole Boulevard ranch to a full-frame impact upgrade near Walsingham Park.

Our Window Replacement Services in Largo

Most Largo homes need one of the services below. The right approach depends on the condition of your existing frames, the size of your rough openings, and what your insurer expects to see. Here’s how we handle each one in Largo specifically.

Full Frame Replacement

Full frame replacement means removing the existing window down to the rough opening, repairing or modifying the surrounding masonry, and setting a brand-new unit with new flashing, new jamb extensions, and a properly shimmed, squared installation. In Largo’s concrete-block ranch homes, this often means cutting back the block opening to accept a modern standard-size window. We do that work in-house with masonry tools, not by shimming an undersized unit into a too-small hole and hoping the caulk hides the gap.

Full frame replacement is the right call when the existing frame is corroded, when the jalousie tracks are so pitted they can’t be salvaged, or when you’re moving from a louvered unit to impact-rated glazing. In Largo, full frame replacement runs roughly $1,100 to $2,600 per opening, depending on size, glass package, and masonry work required.

Insert Window Replacement

Insert replacement leaves your existing frame in place and sets a new window inside it. It’s a strong option for Largo homes where the original frame is still square and intact, and it typically costs less than a full frame replacement. In Largo’s 1960s block homes, we see plenty of aluminum frames that are still structurally sound even when the glass and weatherstripping are shot. In those cases an insert replacement in Largo ranges from $700 to $1,500 per opening.

But insert replacement has limits. If the frame is out of square, if the sill is soft, or if there are signs of water intrusion into the block, an insert will trap the problem. We’ll tell you honestly which applies, and why.

Storm Window Replacement

Largo sits fully inside Florida’s Wind-Borne Debris Region. That means any new window we install must carry a Florida Product Approval number and meet the wind-load requirements for the Pinellas Peninsula, with ultimate design wind speeds near 150 mph. Storm window replacement in Largo means replacing existing single-pane or outdated units with impact-rated or laminated glass that satisfies your insurance carrier. Impact-rated storm windows in Largo typically run $1,400 to $3,200 per opening, depending on size and frame material.

We carry authorized lines from PGT, CGI, and ES Windows for storm-rated work, and we’ll show you side-by-side quotes on paper so you see exactly what each line costs and what each warranty actually covers.

Energy-Efficient Upgrade

Most of the original jalousie windows in Largo have an R-value close to nothing. They leak conditioned air constantly, which is why so many homeowners see their summer electric bills spike from June through September. Replacing them with low-E, argon-filled, double-pane units changes the thermal performance of the whole house. In Largo’s heat, energy-efficient upgrades typically range from $900 to $1,900 per opening for double-pane units in standard sizes, with premium glass packages running higher.

We’ll help you weigh the cost of the glass package against the savings on your FPL bill, and we’ll point you toward the options that pay for themselves fastest in a Pinellas County climate.

Common Window Replacement Problems We See in Largo Homes

• Jalousie windows flagged by insurance companies. Largo’s post-WWII through 1970s building boom left thousands of concrete-block ranch homes with original louvered-glass windows. Pinellas County property insurers now routinely send non-renewal letters citing these windows because they offer essentially zero wind and water resistance. Replacing them properly means modifying the masonry rough opening, not just swapping the louvered sash for a flat pane.
• Corroded aluminum frames from Gulf salt air. Largo sits roughly 5 to 7 miles from the Gulf of Mexico. The persistent salt air oxidizes standard aluminum frames and corrodes door hardware and weatherstripping faster than homeowners expect. We see sashes that bind within two years of installation because someone used a non-marine-grade product.
• Water intrusion at the sill pan on concrete-block homes. Skipping flashing tape at the sill pan on a CBS ranch lets wind-driven rain wick into the block and soften the interior jamb. We see this repeatedly in older Largo homes. It’s a details problem, and it’s the first thing we check when we inspect failed windows.
• Undersized replacement windows shoved into block openings. A cut-rate crew will sometimes jam a smaller window into an existing block opening and fill the gap with caulk and trim. The result leaks wind-driven rain and fails the first time a tropical system pushes water sideways. In Largo, proper replacement often requires cutting and patching block to hit modern standard sizes, which is masonry work most outfits won’t do.
