Fast, Reliable Window Replacement Across South Bay
Window replacement in South Bay comes with a set of problems most window companies never see, and you live with them every day. We’re talking about ground moisture wicking up through concrete slabs, corroded sills on 1960s jalousie frames, and sugarcane ash that settles into every track and seal from November through April. TruePane Windows & Doors has been replacing windows in this lake-shore environment since 2008, and we know what a South Bay opening looks like once the old frame comes out. Call (954) 280-4413 for a free estimate, and we’ll walk you through what your house actually needs.
Why TruePane Windows & Doors Is South Bay’s Preferred Window Replacement Company
Dale Kessler founded TruePane in 2008 on a rule he still keeps on the whiteboard: if the pane is not true, the job is not done. That standard matters more in South Bay than almost anywhere else in Palm Beach County. The chronic moisture off Lake Okeechobee means a window that is out of plumb by a quarter inch will leak within a season. A frame that is not set square will bind when the humidity spikes. We measure every opening twice, quote manufacturer lines side by side on paper, and register both warranty layers before the truck leaves your driveway. No exceptions.
South Bay homeowners who call us get a live person on the phone, 24 hours a day, 7 days a week. Not a voicemail tree, not a callback form. Our background-checked, uniformed technicians work in your home the way they would work in their own mother’s house. Dispatch and scheduling run from our Miami office, but the crews who service South Bay live in the Glades and understand what this lake does to a window frame over twenty years. Every job carries the Done Right Promise and The Keystone Standard: both manufacturer warranty layers registered in writing, durations stated, no arguing if something needs fixing.
Our Window Replacement Services in South Bay
Most South Bay homes were built as modest concrete block structures between the 1950s and 1970s, during the agricultural worker expansion. The original windows are single-pane aluminum or jalousie, and nearly all of them are due. Here is what we do about it.
Full Frame Replacement
A full frame replacement means the entire window comes out, down to the rough opening. In South Bay, this is almost always the right call, because those original aluminum frames are corroded at the sill from decades of ground moisture. Once the frame is out, we inspect the rough opening. What we find in South Bay homes, especially on the concrete block construction of the 1960s, is bottom plates that have been soaked from below for thirty or forty years. We rebuild the sill with pressure-treated blocking, flash with a flood-rated pan, and install the new frame square and true. A typical full frame replacement in South Bay runs $900 to $2,400 per opening depending on size and glass package.

Insert Window Replacement
An insert, sometimes called a pocket replacement, fits a new window into the existing frame. It works when the frame itself is still sound. In South Bay, that is less common than in drier parts of the county, because the moisture that rises off the lake and through the slab eventually compromises most aluminum frames. We will tell you honestly if an insert is a bad investment on a particular opening. When it does work, inserts run $500 to $1,100 per window in South Bay, and the job is typically completed in a single visit.

Storm Window Replacement
South Bay sits in the shadow of the Herbert Hoover Dike, and when a storm pushes water off the lake, it comes at your windows laterally, not straight down. Standard code-minimum flashing tape is not designed for that angle. For storm window replacement, we use flood-rated door pans, elevated threshold heights, and corrosion-resistant hardware on every opening that faces Lake Okeechobee or sits within sight of the dike. Impact-rated glazing is the baseline we recommend for every window in South Bay, not just the ones required by code. Storm window replacement runs $1,200 to $2,800 per opening, with the higher end covering larger commercial-grade impact units.

Energy-Efficient Upgrade
Your single-pane aluminum windows are doing almost nothing against the South Florida heat. A double-pane Low-E insulated glass unit with a thermally broken frame will drop your cooling load immediately. On a 1960s CBS home in South Bay, replacing eight or ten original windows with energy-efficient units typically cuts the summer electric bill by 15 to 25 percent. We quote manufacturer lines like Andersen, ES Windows, and ECO Window Systems side by side on paper, so you see exactly what you are buying and what each line costs. Energy upgrades run $700 to $1,600 per window depending on glass package and frame material.

Common Window Replacement Problems We See in South Bay Homes
South Bay has its own failure patterns. Here is what we find when we open up a South Bay window.
- Corroded sills on original aluminum and jalousie frames. Decades of ground moisture wicking up through the slab eats the aluminum from below. The sash binds, the seal between frame and block fails, and the window stops opening altogether by year two or three.
- Sugarcane harvest ash building up in window tracks. From roughly November through April, the surrounding burn season deposits fine particulate throughout South Bay. That ash settles into aluminum tracks, degrades weatherstripping, and causes sliding windows and sliding glass doors to seize within a single season if they are not flushed come spring.
- Lateral water intrusion during lake storms. Storm surge off Lake Okeechobee pushes water into window flanges at angles that standard code-minimum flashing is not designed to resist. The result is hidden rot behind the stucco, and by the time you see a stain on the interior drywall, the framing behind it is already compromised.
- Fogged seals from chronic humidity. The constant moisture in the air works its way into older double-pane units whose seals have given out. If your window fogs between the panes every morning, the seal has failed and the insulating gas is gone. That unit is done, and no defogging service will fix it permanently.
Pricing for Window Replacement in South Bay, FL
A typical mid-range double-hung replacement in South Bay runs $700 to $1,600 per window. Full frame replacements on concrete block homes start around $900 and go to $2,400 depending on size, glass package, and what we find behind the frame. Impact-rated windows for storm-facing openings run $1,200 to $2,800 each. The single biggest variable in South Bay is what the opening looks like once the old unit comes out. If the bottom plate is rotted from decades of ground moisture, that repair is a line item on the contract, not a surprise on the final bill. We write allowances into every contract for framing and waterproofing repairs, and any change order is priced and approved in writing before we touch it.

FAQs - Window Replacement in South Bay
South Bay’s homes sit close to the dike, and the chronic ground moisture is higher here than in neighboring towns. On a 1960s concrete-block home just off Main Street, our crew pulled a corroded original jalousie unit and found the rough opening’s bottom plate had been soaked for decades by moisture wicking up from the slab. We flashed the new impact-rated double-hung with a flood-rated pan, rebuilt the sill with pressure-treated blocking, and wrote the change order for the rotted framing before reinstalling. The homeowner saw the line item and approved it on the spot. That is the difference: we price the surprise before it becomes a budget breaker. Call (954) 280-4413 for a free estimate and we will inspect your openings first.
If your jalousie windows are original to the home, they are almost certainly not impact-rated and do not meet current Florida Building Code hurricane-protection requirements. Keeping them means your insurance rate goes up and your storm protection is inadequate. We recommend replacing them with impact-rated units, especially on any opening that faces Lake Okeechobee or the dike. South Bay homeowners see the best insurance response when we provide written documentation that impact-rated windows were installed. We register both warranty layers and provide the paperwork your insurer needs.
From November through April, fine ash from the surrounding sugarcane harvest settles into window tracks, degrades rubber weatherstripping, and accelerates oxidation on exposed hardware. On new aluminum sliders, this is the number one cause of binding within the first year. We recommend a spring track flush after burn season ends, and we will show you how to do the routine maintenance yourself. It takes ten minutes. Neglecting it will cost you a service call by November.
Any window or door on the lake-facing side of your home should have a flood-rated pan and an elevated threshold height. The exact numbers depend on your elevation relative to the dike and the finished floor height of your home. A window facing the lake in South Bay should be treated the way you would treat a door threshold in a flood zone: pan, flashing, and hardware that resist lateral water push. We assess this on-site and quote the correct pan and threshold as part of the free estimate.
Yes and no. The humidity causes the fog, but the reason it appears between the panes is that the seal on your insulated glass unit has failed. The desiccant inside the spacer is saturated, and the insulating gas is gone. No defogging service fixes this permanently. The unit needs replacement. In South Bay, we see this on windows that are ten to fifteen years old because the constant moisture load is so hard on sealant. The good news is that a new double-pane Low-E unit properly sealed will not fog, and we guarantee the replacement under The Keystone Standard.
