CWS Windows & Doors in Largo, FL | TruePane Windows & Doors
We provide independent CWS windows and doors service across Largo, from full tear-outs on original aluminum single-hungs in pre-1980 concrete block ranches to weatherstripping and roller replacements on newer CWS sliders. What makes our CWS work different here is simple: we know which frames fail first in salt air, which sashes the building department won’t pass, and what a Citizens wind mitigation inspector is actually looking for. Call (954) 280-4413 for a free CWS estimate in Largo. We are not a CWS dealer or factory-authorized shop. We’re the independent service crew Largo homeowners call when a window has to be right the first time.
Why Largo Residents Choose Us for CWS Service
We’ve worked on CWS windows and doors in Largo long enough to know the difference between a window that needs a ten-dollar sash guide and a frame that’s rotted through at the corners. Most of the 1960s-through-1980s concrete block homes here still carry original builder-grade aluminum, which means CWS 700 Series single-hungs with corroded weep holes and CWS sliders that bind after five years in Gulf air are the norm, not the exception. We keep OEM-equivalent CWS replacement parts on hand for common failures, and we’ll tell you straight when a marine-grade stainless roller or a different weatherstripping profile will outlast the original part. TruePane is led by second-generation glazier Dale Kessler, who grew up pulling jalousie windows apart in Fort Lauderdale and has spent more than two decades working glass and framing along Florida’s Gulf coast. We measure twice before we touch anything, we write both manufacturer warranty layers down on paper, and we answer the phone when you call.
Common CWS Windows & Doors Problems We Solve in Largo
Every window line has its failure patterns. These are the ones we see repeatedly on CWS units in Largo, usually tied to salt spray, age, or the original installation.
- Corroded frame corners at the weep holes. On CWS aluminum frames facing the Gulf, salt-laden air wicks into the weep holes and swells the miter joints. The corner starts to lift, then water gets behind the frame. By the time the homeowner sees the bubbling paint, the metal underneath is often too thin to save. We replace the frame or the window, we don’t patch over rot.
- Fogged dual-pane glass and failed IGUs. CWS insulated glass units in homes less than two miles from the Gulf routinely fog within five to seven years. The seal around the spacer fails, moisture gets in, and the window loses both clarity and insulating value. That’s a glass-pack replacement if the frame is sound, or a full unit if the aluminum has gone soft.
- Binding or seized sliding sashes. Galvanic corrosion where the steel roller meets the aluminum track is common on CWS 800 Series sliding windows in Largo. The sash gets harder to move every year until it won’t move at all. Sometimes the fix is a roller swap and a track clean. Other times the corrosion has pitted the track itself and the window is done.
- Failed single-pane originals at wind mitigation inspection. Original CWS single-pane windows on older Largo homes don’t meet current Pinellas County wind-borne debris requirements. Homeowners who planned to just “fix up” their old windows find out at the inspection that everything has to come out. We handle the full replacement, permit and all.
- Weep hole blockages on Gulf-facing walls. Largo’s salt air doesn’t just corrode, it also carries fine sand that plugs CWS weep holes. Water backs up in the track, seeps into the frame, and accelerates the corrosion. A simple detailing job we do on almost every Largo CWS service call is cleaning and clearing those lower tracks so the window drains the way it was designed to.
CWS Service in Largo: What Local Conditions Mean for Your Equipment
Here’s the thing most window companies won’t tell you about Largo. The city sits less than five miles from the Gulf, and a significant share of its housing stock is 1960s and 1970s concrete block ranch homes still wearing original jalousie louvered windows or single-pane aluminum sliders. Those jalousie windows cannot be retrofitted, repaired, or “brought up to code” to satisfy a Citizens Property Insurance wind mitigation inspection. They are a full tear-out-and-replace job by definition. Largo has one of the highest concentrations of these pre-1980 jalousie openings in Pinellas County outside Cws repair in Clearwater, which means homeowners here face a mandatory replacement situation more often than in almost any other community on the peninsula. If you own a CWS-fitted Largo home and you’ve been holding off on replacement, here’s the math: a contractor who quotes you a “repair” on a jalousie window is selling you a job the building department will never pass. We’ve replaced jalousies with impact-rated CWS-compatible units on streets all around Largo Medical Center and the neighborhoods off East Bay Drive, and every one of those jobs started with the same honest conversation: this one isn’t a repair, it’s a replacement, and we’ll do it to the Florida Building Code the first time.
CWS Models & Products We Service in Largo
We service CWS 700 Series single-hungs, the original builder-grade aluminum that went into thousands of Largo homes. We service CWS 800 Series sliding windows, the ones that bind up when steel rollers and aluminum tracks corrode together. We service CWS 900 Series casements and awnings, and we service CWS impact-rated picture windows, the kind installed after the 2002 Florida Building Code retrofit. For parts, we prioritize OEM-equivalent CWS replacements: sash guides, cam locks, weatherstripping profiles, and the like. But when an original part has a known weakness in salt air, we’ll tell you and offer an aftermarket alternative that outlasts it, like stainless rollers or marine-grade sealant. Any CWS window older than fifteen years in Largo with frame corrosion or a failed IGU gets a straight recommendation for replacement. Not because we want to sell a window, but because saving the old unit costs more over the next five years than pulling it.
CWS Service Pricing in Largo
CWS service in Largo spans a wide range. A roller replacement or weatherstripping job on a single window typically lands between $180 and $340. A dual-pane insulated glass replacement on a CWS window runs $350 to $850 depending on size and glass package. Full frame replacement of an original CWS 700 Series with an impact-rated unit starts around $900 to $1,800 per window installed, with the final number driven by opening size, the product you choose, and whether the rough opening needs reframing. Every estimate we give includes a written, line-by-line price. Call (954) 280-4413 and we’ll put one together for your Largo home, free.

FAQs - CWS Windows & Doors in Largo
Yes. Any replacement of a CWS window or door in Largo that changes the opening size, product type, or structural performance requires a permit. Pinellas County building departments actively enforce this, especially on wind-borne debris upgrades. We pull the permit, handle the inspection, and give you the paperwork before we leave.
Like our Cws service in Indian Rocks Beach, it depends on the window and the insurance inspection. If the window is a standard CWS single-hung or slider in sound condition, a repair like a roller swap or weatherstripping replacement may be fine. But if the opening has jalousie louvered windows or original single-pane units that don’t meet Pinellas County wind-load standards, the inspector won’t pass it. No repair fixes that. You replace it or you don’t get the discount. We’ll tell you which category your window falls into before we touch it, and we’ll give you a free CWS replacement quote if that’s where you land. Call (954) 280-4413 and we’ll walk you through it.
Because the steel rollers on the sash react with the aluminum track when salt air and moisture get involved. Galvanic corrosion sets in, the roller seizes, and the sash drags. In Largo, where Gulf air sits on the windows year-round, this happens faster than inland. The fix is usually stainless rollers and a thorough track cleaning. In worse cases, the aluminum track itself has pitted and the window needs to go.
Only if the window carries a valid Florida Product Approval number and is properly installed with the right fasteners and flashing for the current code. Most original CWS aluminum from the 1960s to 1980s doesn’t. Some CWS impact-rated picture windows installed after 2002 do. If you’re not sure, call us. We’ll check the stickers, the frames, and the installation, and tell you straight whether the window will pass or has to come out.
We can make the opening smaller. In poured concrete block walls, reducing an opening is easier than enlarging one because you’re filling in with block or framing rather than cutting the wall. Many Largo ranch homes have oversized original jalousie openings that go down to the floor. We often reduce those to a standard window height. You’re not locked into the old CWS size. Call (954) 280-4413 for a free measurement and we’ll show you your options.
