PGT Window Replacement: The Westchester Owner’s Guide
PGT window replacement in Westchester typically runs $450 to $1,200 per window installed, depending on the series and glass package, and we can usually have a crew at your house within a few days of pricing the job. Most homeowners discover they need a replacement when a seal fails and fog creeps between the panes, or when a impact-rated unit finally gives out after one too many South Florida storms. We stock PGT-compatible hardware and glass on our trucks, and our techs have been matching these units to Westchester homes for over a decade.
PGT is the most common impact window brand in Miami-Dade County, and Westchester is no exception. The ranch homes off Coral Way and the mid-century builds near Tropical Park often have original PGT units from the 1990s or early 2000s. Back then, the glazing systems were simpler, the laminate was thinner, and the weatherstripping was not built for 15 years of salt air and afternoon monsoons. When those units fail, you need a replacement that matches the frame dimensions, glass specs, and structural load requirements of the original opening. That is not a job for a handyman with a tape measure and a prayer.
Which PGT Models This Applies To
PGT makes several window series, and the replacement path depends on which one is in your wall. The most common in Westchester are the WinGuard line (aluminum and vinyl impact windows), the Spectrum line (vinyl, non-impact, often from the 1990s), and the PGT 700/770 Series (aluminum, single-hung and horizontal roller, heavy presence in older Miami-Dade housing stock). Each series uses different frame depths, glass thicknesses, and hardware geometry, so matching the model is not optional. It is the difference between a window that slides like new and one that binds, leaks, or fails the next wind mitigation inspection.
To identify your unit, look for a small etched label in the corner of the glass or on the frame edge. It will list the series, the glass package (like “IG” for insulated glass or “Lami” for laminated impact glass), and the manufacturing date. If the label is worn off, our techs measure the frame, the glass thickness, and the overall opening to reverse-engineer the right replacement. One gotcha: PGT changed frame-wall dimensions slightly between the 700 and 770 series, so a glass unit cut for one will not seat correctly in the other. We have seen homeowners order glazing online based on a model number alone and end up with a unit that is an eighth of an inch off in every direction. Measure before you order, or just call us and we will get it right the first time.
OEM vs. aftermarket: For impact glazing, we strongly recommend OEM or OEM-equivalent PGT spec glass. Aftermarket laminated glass can pass a visual check but fail a missile test because the interlayer or the edge seal is not certified to the same standard. For hardware like balances, rollers, and locks, quality aftermarket equivalents are fine and often cost 30 to 40 percent less than branded parts without losing durability. We will always tell you which route makes sense for your specific window.

Signs Your PGT Window Replacement Is Failing
- Fog or condensation trapped between the panes. This is a failed insulated glass seal. The desiccant inside the spacer has saturated, and the unit is now permanently fogged. No cleaning or defogging service will reverse it. Once the seal is gone, the gas fill is gone with it, and your energy efficiency drops.
- Water staining on the sill or drywall below the window. The weep holes may be clogged, or the frame seal has failed. In Westchester, where afternoon thunderstorms hit sideways, water intrusion around a PGT frame usually means the exterior sealant has dried and cracked. Replacing the sealant is a repair; a warped frame or cracked corner joint means the window goes.
- The sash binds, sticks, or drops when opened. Worn balance shoes or spiral balances are the usual culprits. Older PGT single-hungs have metal spiral balances that corrode in humid air. If the sash won’t stay up, the window is not just annoying, it is a pinched-finger risk for anyone with kids in the house.
- Crank hardware spins but the window does not move. On PGT casement and awning windows, the operator gear strips after years of use, especially if salt air has eaten the gears. You can replace the operator, but if the sash hardware is also corroded, a full replacement window starts looking like the more economical call.
- Visible lamination clouding or discoloration in impact glass. Impact glass has a plastic interlayer between two panes. Over time, UV exposure and moisture can cause the interlayer to haze. The window still protects you structurally, but visibility is shot. This is a planned replacement, not an emergency, but it will not improve on its own.
Replacement Cost & What’s Included
Here is what we currently see for PGT window replacement in Westchester, installed:
- Single-hung, vinyl, non-impact: $450 to $700
- Single-hung, aluminum, non-impact: $550 to $850
- WinGuard impact single-hung: $800 to $1,200
- Horizontal roller (PGT 700/770), non-impact: $500 to $850
- Casement or picture window, custom size: $900 to $1,500+
Those ranges include the unit, the haul-away of the old window, proper flashing and sealing, and our labor warranty. What moves the price: glass package (insulated vs. laminated impact), frame material, overall size, and whether the opening has water damage that needs repair before the new unit goes in. If you call us, we give you a written line-item quote before any work starts. No change orders, no squirrelly “unexpected conditions” markups. The price we agree on is the price you pay.

DIY or Call Us?
A homeowner in Westchester can safely check a few things before calling anyone: look for cracks in the frame corners, check whether weep holes are clear of dirt or paint, and document when the fog or sticking started. These observations speed up our diagnosis when you call.
Where DIY goes wrong is removal. A PGT impact window is not a standard residential sash. These units are heavy, often 60 to 90 pounds for a mid-size single-hung. The removal requires cutting through the exterior sealant, disengaging the balance system safely, and lifting out a unit that can pull you off a ladder. Broken glass from a dropped impact window is not regular glass; the laminate holds the shards together in dangerous, heavy sheets. If the replacement is not flashed and leveled correctly, you trade a cosmetic problem for a water intrusion problem that rots your framing over time. Replacing one window safely is a two-person job with the right lift tools and sealants. We do it every day. Call (863) 251-5864 and we will give you a straight answer about what your window needs and what it will cost before you touch a screwdriver.
FAQs
A PGT window in our climate typically lasts 15 to 25 years before the insulated glass seal fails or the hardware wears out. Salt air, intense UV, and storm-driven rain shorten that lifespan compared to inland Florida. Impact windows hold up structurally longer than non-impact, but the glass seals fail on roughly the same timeline. Call (863) 251-5864 if your windows are in that age window and starting to fog or bind; we will tell you honestly whether you have two years left or need to plan a replacement now.
Depending on the failure, yes. Failed balances, worn rollers, bad crank operators, and exterior sealant are all repairable parts. A fogged insulated glass unit or a broken impact laminate cannot be repaired; the glass unit is replaced. In many cases, we can replace just the glass unit inside your existing PGT frame, which saves money over a full-frame replacement. Call us and describe what the window is doing; we will tell you which path applies.
For a standard-size, in-stock PGT or PGT-compatible unit, the actual swap takes one to two hours per window. Custom-size impact glazing orders add one to three weeks for fabrication. We arrive, prep the opening, remove the old unit, set the new one, flash and seal the exterior, and haul everything away the same day. Small jobs are one day; multi-window replacements we schedule in sequence.
We stock common PGT-compatible hardware on our trucks: spiral balances, block and tackle balances, rollers, crank operators, latches, and weatherstripping. Glass units are cut and fabricated to spec, so those are ordered, but we take exact measurements during your estimate visit and do not guess. We also source parts for CGI, CWS, and ES Windows when we are already on a job, so if you have a mixed-brand house in Westchester, one visit covers it.
