ViewLux Window Replacement: The Lighthouse Point Owner’s Guide
ViewLux window replacement in Lighthouse Point typically runs $340-$780 per opening installed, depending on frame material, glass package, and whether the original is nail-fin or block-frame construction. We stock ViewLux-compatible frames and hardware for every series the company has sold in South Florida since 2015, and most Lighthouse Point jobs we measure in the morning are opened and closed the same week. Homeowners usually figure out something’s wrong when the sash won’t stay up on its own, or when they notice the daylight gap along the meeting rail after a cold front passes through.
Which ViewLux Models This Applies To
ViewLux organizes its residential line into three series: the VL-100 single-hung and slider for entry-level replacement, the VL-300 double-hung and casement with reinforced frames, and the VL-500 impact-rated line that carries Miami-Dade NOA certification. The part that fails, and the replacement frame that fits, differs materially between them.
Check the spacer bar in the glass unit or the etched corner logo on the sash itself. VL-100 units use a 2-5/8 inch frame depth; VL-300 and VL-500 step to 3-1/4 inch. That three-quarter inch difference is the compatibility gotcha we see most often in Lighthouse Point: a homeowner orders a VL-300 replacement to fit a VL-100 rough opening and ends up with drywall repair on both sides. The balance shoe and tilt-latch hardware are also series-specific. ViewLux changed its tilt-latch geometry after 2019; pre-2020 and post-2020 latches look identical from the room side but do not interchange.
We carry both OEM ViewLux sashes and, where the original part is back-ordered, verified aftermarket equivalents that match the original U-factor and SHGC ratings. For impact-rated units, we do not substitute. The NOA traceability matters for Lighthouse Point’s wind-borne debris requirements, and our documented photo record includes the label photograph for your permit file.
Signs Your ViewLux Window Replacement Is Failing

- The sash drops or won’t stay open. This is almost always a failed coil balance or broken balance shoe in the jamb liner. In Lighthouse Point, we see this accelerate in units facing the Intracoastal, where salt air corrodes the balance spring coating inside two to three years of installation.
- Visible fog between the glass panes. The insulated glass unit (IGU) seal has failed and the desiccant is saturated. Once you see haze, the Low-E coating is already degrading from moisture exposure. The fix is a full sash replacement, not defogging.
- Air movement at the meeting rail or frame perimeter. The weatherstrip has compressed past recovery or the sash is out of square from settlement. We check with a smoke pencil during survey; if the leak exceeds 0.25 cfm per foot, we specify replacement over repair.
- The lock engages but the sash still rattles. The keep or strike plate has wallowed out, or the frame itself has shifted in the buck. This is structural, not hardware, and patching the lock hole just delays the replacement.
- Cracking or delamination at the exterior frame corners. UV and thermal cycling have degraded the vinyl or fiberglass substrate. We see this most on west-facing ViewLux VL-100 units in Lighthouse Point, where afternoon sun hits raw wall with no overhang protection.

What moves the number: frame material (vinyl vs. aluminum-clad), glass package (clear, Low-E, or impact-laminated), and whether the original installation used a nail fin that we can reuse or a block frame that requires interior trim removal. Every Sightline quote in Lighthouse Point includes the measured survey you keep, the written scope, and the photo record. The price on the page is the price on the invoice. Haven Clause 1: Have it in writing.
Our 365-Day Done Right Promise covers the installation, the seal, and the operation. If the sash drags or the balance fails in year one, we return and correct it. The manufacturer’s glass warranty runs 20 years; we document the serial number in your file.
DIY or Call Us?

There is one thing a Lighthouse Point homeowner can safely verify: open the sash, look for the etched ViewLux logo and the NFRC label in the corner, and photograph both. That tells us the series, the glass package, and the manufacturing date before we arrive.
What we do not recommend: removing a sash with failed balances without supporting the glass weight first. An unrestrained double-hung sash weighs 35-50 pounds and will drop hard enough to crack the unit or injure hands. The balance springs are under tension; releasing them without a winding tool damages the jamb liner. For impact-rated units, disturbing the glazing bead without the proper setting block sequence voids the NOA and your insurance documentation.
We are an independent service provider, not affiliated with ViewLux. We stock the common failure parts on our Lighthouse Point trucks and carry the full frame inventory at our warehouse. If you have the model series and a description of the symptom, call (754) 600-8907 and we will schedule the measured survey. Measure twice, write it down, then we talk price.
FAQs
Twelve to eighteen years for standard vinyl units, fifteen to twenty for impact-rated, assuming the original installation was square and flashed correctly. Salt air and direct west exposure shorten that by 20-30 percent; we specify upgraded hardware and marine-grade weatherstrip for canal-front properties. Call (754) 600-8907 for an exact quote on your opening.
Sometimes. A failed balance shoe or tilt latch is repairable if the jamb liner is undamaged and the sash frame is square. Fogged IGUs, cracked frames, or sashes out of square more than 1/8 inch across the diagonal require replacement. We tell you which during the survey, in writing, before you decide. Call (754) 600-8907 for a free estimate.
A single sash replacement takes two to three hours on site; a full frame replacement in an existing block opening takes four to six hours including trim repair. We do not rush the sealant cure or the final operation check. Call (754) 600-8907 to schedule.
We stock balance hardware, weatherstrip, and replacement sashes for VL-100, VL-300, and VL-500 series on our Lighthouse Point trucks. Full frame units and custom sizes ship from our warehouse with three-day lead time. Call (754) 600-8907 to confirm availability for your model.
