AfterFast, Reliable Window Installation Across Largo
Window installation in Largo usually means one thing: an older concrete-block house with original jalousie windows that an insurer will not cover anymore. We replace those units with impact-rated, Florida Product Approved windows sized correctly for a CBS rough opening, then register both warranty layers before our truck leaves your driveway. We serve every Largo neighborhood, from Keene Park to the retirement subdivisions along East Bay Drive, and a live person answers when you call (813) 320-9346. Most Largo estimates run free, and the quote you sign is the price you pay with no change orders unless you approve them in writing first.
Why TruePane Windows & Doors Is Largo’s Preferred Window Installation Company
We did not buy our way into Largo with a franchise playbook. Dale Kessler founded TruePane in 2008 on a rule that still governs every install: if the pane is not true, the job is not done. Homeowners across Largo have seen the difference between a crew that slaps a window into a rotten buck and one that cuts the block, patches the masonry, and flashes the opening so it stays dry for decades.
Our technicians are background-checked and uniformed. They measure every opening twice. They quote manufacturer lines side by side on paper so you see exactly what you are buying, whether that is a single-hung impact unit or a casement window with stainless hardware. We are an authorized installer for more than a dozen lines, including Andersen, Pella, Marvin, Milgard, PGT, and CGI. Largo customers get the same straight answer every time: a square deal, written down, with the 90-Day Done Right Promise behind it.
Dispatch and scheduling for Largo are coordinated from our South Florida office, but the crews working in your home live and work right here in Pinellas County. When a Keene Park homeowner calls about a failed seal on a jalousie replacement we installed two years ago, we answer the phone and we come back. That is the standard. It is also why Largo homeowners who have been burned by cut-rate crews call us first when the next opening fails.

Our Window Installation Services in Largo
Single & Double Hung Windows
Most Largo ranch homes were built with jalousie windows, and when those come out, homeowners usually choose single or double hung for the master bedroom and living areas. Double hung units give you top and bottom ventilation, which matters in a Gulf climate where cross-breeze is the difference between running the AC at 74 and running it at 78. In a CBS wall, the opening rarely matches a standard modern size, so we cut and patch block as needed and set a custom-fabricated buck to carry the new frame. A typical double hung replacement in Largo runs $850 to $1,400 per opening installed, plus permitting.
Casement Windows
Casement windows seal tighter than any other operating style, which is why we recommend them for Largo homes facing the Gulf breeze corridors. The crank mechanism pulls the sash against the weatherstripping on all four sides when closed, and a quality casement from Andersen or Marvin shrugs off salt air better than a builder-grade hung unit. Casement replacement in Largo falls between $900 and $1,500 per window depending on the finish and impact rating.
Fixed & Picture Windows
Fixed and picture windows are the workhorse of any Largo living room looking east toward Tampa Bay or west toward the Gulf. They do not open, so they cost less to buy and seal better than any operable unit. The tradeoff for CBS homes is thermal expansion: a large fixed window in a masonry wall needs a properly sized buck and expansion clearance, or the seal fails in three years. We size picture windows for Largo’s heat and humidity, not for a California spec sheet. Expect $700 to $1,200 per installed fixed unit.
Awning Windows
Awning windows hinge at the top and open outward, which works well for the short, wide rough openings common in 1960s Largo CBS construction. They shed rain naturally when open, a real advantage during Pinellas County’s summer afternoon downpours. In original jalousie openings, we often recommend awnings in bathrooms and kitchens where code requires egress or ventilation. Largo pricing for awning replacements generally lands between $750 and $1,250 per window installed.
Trusted Brands We Service in Largo
We quote side by side so you can compare what you are actually buying. For Largo’s Wind-Borne Debris Region requirements, we regularly install Andersen impact lines, PGT WinGuard, and CGI Estate Collection units, all with Florida Product Approval numbers on file. For homeowners who want European engineering in a coastal package, we carry ES Windows and ECO Window Systems. Our Largo customers do not wait on parts from out of state. We stock common replacement hardware for Andersen, PGT, and ES Windows locally, so a failed balance or latch gets fixed fast, and a warranty claim starts the day we document it, not the day a distributor returns a call.
Common Window Installation Problems We See in Largo Homes
- Rotted original bucks behind jalousie frames. The 1950s through 1970s CBS boom in Largo put unflashed jalousie frames directly into wood pack-outs, and decades of Gulf salt air wicked behind them. A new window bolted into that rot fails within two seasons.
- Misaligned block courses in original rough openings. Older Largo block work was not always laid to modern tolerances. Hitting a misaligned course means cutting and patching masonry to hit a square, watertight opening, which is a skill set most window-chain crews do not have.
- Insurance-required impact upgrades done with generic units. A homeowner replaces jalousies to satisfy a Citizens Insurance non-renewal letter, then fails re-inspection because the installer used a non-Florida-Product-Approved unit. That is a five-figure mistake we see too often on Largo re-inspections.
- Salt-air corrosion on frames and hardware. Largo sits five to seven miles from the Gulf, and the persistent salt air oxidizes aluminum frames and weatherstripping fast. Non-marine-grade hardware corrodes in a single season, and the homeowner is left arguing with a warranty department that does not answer.
Pricing for Window Installation in Largo, FL
Window installation in Largo runs higher than inland Florida because CBS masonry work and Wind-Borne Debris Region compliance add real labor to every opening. A basic builder-grade single hung in a standard wood-framed wall runs $650 to $900, but few Largo homes have standard wood-framed walls. For CBS construction, expect $850 to $1,400 per double hung, $900 to $1,500 per casement, and $700 to $1,200 per fixed unit. Impact-rated glazing required for insurance compliance adds 30 to 45 percent per opening. Full-house jalousie replacement in a typical three-bedroom Largo ranch lands between $14,000 and $28,000 with permitting, masonry patching, and custom bucks included. Call (813) 320-9346 and we will put a written line-item quote in your hand before you commit to anything.

FAQs - Window Installation in Largo
A Largo permit requires the inspector to verify that the rough opening meets current wind-load and water-resistance codes, which means the wall around your existing window gets opened far enough to see whether the original framing is still sound. In CBS homes from the 1950s through 1970s, that inspection often reveals rotted wood bucks and failed waterproofing behind unflashed jalousie frames. That is not a surprise we spring on you later. It is exactly why we inspect the opening before we quote, write allowances into the contract, and document every change against the signed scope so the final invoice matches what you approved. Call (813) 320-9346 to schedule a free opening inspection in Largo.
Yes, in most cases we replace jalousies with modern double hung units without rebuilding the whole wall. A jalousie rough opening is short and wide, so we cut and patch the block to hit a standard double hung size, then install a custom-fabricated buck with full flashing tape and marine-grade anchors. The masonry work is the part that separates an experienced Largo installer from a crew that only knows wood framing. On a Keene Park jalousie replacement, our crew found the 1962 pack-out rotted from salt wicking, cut the block back to sound masonry, and rebuilt the opening so the new impact-rated double hung sealed tight. The invoice matched the signed scope because we documented every step against the contract allowance. Call (813) 320-9346 for an exact quote on your Largo home.
A Citizens Insurance non-renewal letter citing jalousie windows requires replacing those openings with impact-rated or hurricane-protected windows that carry current Florida Product Approval for the Wind-Borne Debris Region. The insurer will typically require documentation showing the new units meet the design wind pressure for your specific Largo location, which sits within a zone with ultimate design wind speeds near 150 mph. We handle the entire documentation package, from Florida Product Approval numbers to the permit sign-off and the final inspection report, so you can send your insurer a complete file that satisfies the non-renewal condition. Call (813) 320-9346 and we will walk you through what your specific letter requires, free.
Largo sits on the Pinellas Peninsula, five to seven miles from the Gulf of Mexico, and the salt air here is persistent and aggressive. Aluminum frames oxidize, steel hardware rusts, and weatherstripping breaks down years faster than it does in Tampa or Plant City. Homes that got builder-grade or non-marine-rated hardware during the 1990s and 2000s are the ones we see with failed seals and stuck operators today. We specify marine-grade stainless hardware and corrosion-resistant finishes on every Largo install, and we stock common replacement hardware locally so a broken latch or balance gets fixed without a six-week backorder. Call (813) 320-9346 if your Largo windows are binding or the hardware is flaking.
Our inspection-first process means we open up the rough opening before we give you a final number, not after you have signed a contract. In a Largo CBS home, that inspection reveals rotted wood bucks, misaligned block courses, and failed waterproofing before we quote, so those costs are written into the contract as allowances with a documented approval process for anything beyond the signed scope. That is the difference between a quote that holds and a surprise change order that stalls the job. We put every scope item in writing, price each allowance honestly, and the final invoice matches what you approved. Call (813) 320-9346 to schedule a free inspection and get a written quote that will not move.
If your Largo home still has original jalousie windows, or if you have a non-renewal letter sitting on the kitchen counter, call (813) 320-9346 today. We will inspect the openings, walk you through the masonry and insurance requirements, and put a written quote in your hand. The estimate is free, and the price you approve is the price you pay.
