New windows and doors improve comfort, cut energy bills and add long-term value to your home. Sightline Windows & Doors Olympia Heights pairs proven product lines with our own installing crews for lasting performance - and a price we put in writing.
1. Choose your installer
The unit is half the job - the install is the other half. Our own background-checked crews measure, set, seal and insulate every opening, and they know the lines we quote inside and out because they install them every week.
2. Select the right products
Compare styles, materials and glass packages side by side until the fit is right for your rooms, your budget and your goals. The product-line comparison below is the place to start.
3. Prepare your home for install
Before install day we walk you through a short checklist - furniture pulled back, treatments down, a clear path to each opening - so install day is watch-it-happen, not scramble.

PGT Window Replacement: The Olympia Heights Owner’s Guide
PGT window replacement in Olympia Heights typically runs $340-$780 per opening for standard vinyl impact-rated units, installed, with most jobs scheduled within 48 hours of the measured survey. We stock PGT-compatible hardware, glazing beads, and sash assemblies on our trucks, and we carry full product lines from PGT, CGI, and CWS for same-week completion when the frame is salvageable. Most Olympia Heights owners discover a PGT window has failed when the sash won’t stay open, water pools on the sill after a summer storm, or they notice daylight between the frame and the wall - signs that the glazing seal, balance system, or installation flange has reached end of life in South Florida’s UV and salt-air cycle.
Which PGT Models This Applies To
We replace glass, hardware, and full sash assemblies across PGT’s major residential lines: WinGuard vinyl and aluminum series, EnergyVue vinyl, and the PremierVue aluminum line. The critical compatibility check is the manufacturing date stamp, found on the spacer bar inside the insulated glass unit or on the hinge-side jamb label. PGT revised its frame profiles in 2018 and again in 2022, meaning a 2016 WinGuard sash will not seat properly in a 2022 frame without adapter glazing beads that most big-box suppliers don’t stock.
For part matching, we photograph the label, measure the daylight opening to the sixteenth, and cross-reference PGT’s parts matrix before ordering. OEM PGT parts maintain the original impact rating and warranty chain; quality aftermarket equivalents exist for balances, locks, and weatherstripping, but we won’t install aftermarket glass or sash frames on impact-rated units because the HVHZ (High Velocity Hurricane Zone) certification does not transfer. Sightline Windows & Doors Olympia Heights is an independent service provider, not affiliated with PGT. We source through PGT’s authorized distribution channel in Miami-Dade County.
Before
AfterSigns Your PGT Window Replacement Is Failing
- Sash drops or won’t stay open. The coil balance or constant-force spring has fatigued, typically after 8-12 years in Olympia Heights’ heat and humidity. PGT’s newer systems use a different balance shoe width, so matching the series year matters.
- Condensation between glass panes. The insulated glass unit (IGU) seal has failed, allowing moist air into the airspace. In South Florida, this accelerates once the desiccant saturates, usually visible as a permanent haze that won’t wipe away.
- Water intrusion at the sill or jamb. The glazing bead has shrunk or the weep system is clogged with salt and debris. We see this most often on east-facing PGT units near the Bird Road corridor, where morning sun drives rapid expansion cycles.
- Frame corner separation or warping. Vinyl profiles soften in sustained heat; poor installation with inadequate shimming lets the frame rack. A level check of the diagonal reveals whether the opening or the frame has moved.
- Lock misalignment or hardware corrosion. The multipoint lock no longer draws the sash tight against the weatherstrip. Salt air attacks zinc-alloy hardware faster than stainless; PGT upgraded to 316 stainless components in 2020.
Replacement Cost & What’s Included
| Component | Typical Range (Installed) |
|---|---|
| IGU replacement (glass only) | $340-$520 |
| Sash assembly (frame + glass) | $480-$680 |
| Full frame replacement | $620-$780 |
| Hardware set (locks, balances, lifts) | $180-$290 |
What drives the range: unit size, floor level (lift equipment for second-story), and whether the original installation used proper flashing integration. Our quote includes removal, disposal, new parts, installation per PGT’s published guidelines, and a documented photo record of the rough opening before we close it up. The price we write is the price on the invoice - Haven Clause 1. Every PGT replacement carries our 365-Day Done Right Promise under the Haven Standard.
DIY or Call Us?
An owner can safely check three things: verify the PGT label location, clear weep holes with a pipe cleaner, and confirm the lock engages fully without forcing. Beyond that, PGT impact-rated windows contain tempered or laminated glass under compression; improper handling during sash removal risks spontaneous breakage. The balance systems store significant tension, and a slipped tool can damage the frame or the operator.
We don’t recommend homeowner disassembly of the sash or IGU on any impact-rated unit. The glazing stop geometry is specific to PGT’s series year, and incorrect reassembly voids the impact certification that your insurer and building department rely on.

FAQs
PGT vinyl impact windows typically perform 15-20 years in South Florida before major component replacement, though IGUs may need replacement at 10-14 years due to seal fatigue from thermal cycling. East- and south-facing units experience faster weatherstrip and hardware aging. Call (786) 400-2761 for an exact assessment - estimates are free.
A failed IGU cannot be repaired; the seal is factory-set and the desiccant is non-serviceable. Single-pane cracks in non-impact units can sometimes be stabilized, but PGT’s laminated impact glass requires full IGU replacement to maintain the HVHZ rating. Call (786) 400-2761 for an exact quote - estimates are free.
IGU or sash replacement in an existing PGT frame typically takes 90-150 minutes per opening, assuming no structural damage to the rough opening. Full frame replacement requires 3-5 hours including flashing integration and air-sealing. We schedule the measured survey first, then return with the confirmed part. Call (786) 400-2761 to book.
We carry PGT-compatible balances, locks, glazing beads, and standard sash sizes for the WinGuard and EnergyVue lines. Custom sizes and 2022+ profile hardware are sourced from Miami-Dade distribution with 24-48 hour turnaround. We confirm part availability during the measured survey so there’s no gap between diagnosis and installation. Call (786) 400-2761 to schedule.
Sonia Raman and her crew have worked the Olympia Heights market long enough to know that a PGT frame installed without a level rough opening won’t make it through the second rainy season without weep failure. She still measures every opening herself before the quote - “Measure it right the first time. Everything after that is just paperwork.” - which is why her change-order count stays close to zero.
Ready for a written price before any work starts? Call (786) 400-2761 to schedule your free measured survey. We’ll bring the PGT parts catalog, confirm your series year, and leave you with a documented scope you can compare against any other quote.
