ViewLux Home Additions & ADU Nationwide

ViewLux Home Additions & ADU: The Boca Raton Owner’s Guide

We stock and install ViewLux-compatible components for home additions and ADU projects in Boca Raton, with typical installed pricing from $45,000 to $130,000 for full additions and $90,000 to $220,000 for detached ADUs. Most ViewLux hardware and finishing systems are available with documented lead times, and we carry common fasteners, flashing, and trim profiles on our trucks. Most Boca Raton owners discover a ViewLux component has failed when they notice water intrusion at the addition-to-existing wall junction, or when the integrated window-wall system shows separation at the header after a storm season.

Which ViewLux Models This Applies To

ViewLux produces three product lines relevant to South Florida additions: the ViewLux 300 Series (stick-framed glass wall systems up to 10 feet), the ViewLux 500 Series (structural aluminum-framed curtain wall for two-story applications), and the ViewLux ADU Pro (a pre-engineered panelized system with integrated MEP rough-ins). The 300 Series uses a proprietary two-part spline connection that mates to conventional wood framing; the 500 Series requires a steel or engineered-lumber subframe with specific deflection limits. The ADU Pro ships with its own foundation connection detail, but Boca Raton’s high water table and sandy soils often require modification to the standard pier spec.

To identify your system, check the aluminum extrusion for a stamped series number near the corner key, or the glass edge for a ViewLux tempering mark with a four-digit date code. The OEM weatherstrip and gaskets are color-coded by series: gray for 300, black for 500, blue for ADU Pro. We source OEM gaskets and corner keys directly from ViewLux distribution in Miami, but we also stock compatible aftermarket EPDM from Pemko and Ultrafab for same-day seal repairs. The aftermarket option saves roughly 30 percent on material but carries a shorter warranty; for the 500 Series, we recommend OEM corner keys because the thermal break geometry is proprietary and third-party keys have cracked in our experience during Boca Raton’s summer heat cycles.

Signs Your ViewLux Home Additions & ADU Is Failing

• Water staining at the head jamb or sill. ViewLux systems rely on a continuous sill pan and end-dam flashing that gets disrupted when the EPDM compression gasket hardens in Florida UV. Once the gasket loses pliability, wind-driven rain pushes past the sill cap and into the subfloor framing. We see this most often on east-facing walls after three to four years of exposure.
• Glass panel fogging between lites. The 300 and 500 Series use insulated glass units with a warm-edge spacer; seal failure allows moist Boca Raton air into the airspace. The desiccant saturates, and the fog becomes permanent. This is a glass replacement, not a frame issue, but owners often misdiagnose it as a leak from above.
• Operational binding in sliding or folding panels. ViewLux hardware runs on stainless steel rollers in an aluminum track. Coastal salt air corrodes the axle pins even through the factory lubrication, and the panel drags or jumps. Left unaddressed, the operator forces the panel and bends the track extrusion.
• Visible separation at the wall-to-addition joint. The ViewLux ADU Pro uses a slip-joint at the roof-wall intersection to accommodate settling. If the cover flashing lifts or the backer rod extrudes, the joint is no longer weather-tight. In Boca Raton’s flat-roof additions, this is often the first sign of inadequate slope at the tie-in.
• Interior condensation on aluminum frames. When the thermal break in the 500 Series extrusion degrades or was improperly installed, the interior aluminum surface drops below dew point. This indicates the frame is conducting exterior temperature directly inside, which means the polyamide strip has slipped or the cavity foam has settled.

Replacement Cost & What’s Included

ViewLux component repair and replacement in Boca Raton falls within our standard home addition pricing structure. A gasket and seal restoration on a 300 Series wall runs $2,800 to $5,500. Individual insulated glass unit replacement is $800 to $1,800 per lite depending on size and low-e coating. Full track and roller hardware replacement on a 16-foot opening is $3,500 to $7,000. For ADU Pro panelized systems with multiple failed connections, sectional replacement ranges from $12,000 to $28,000.

What drives the range: accessibility (second-story work requires staging), glass spec (impact-rated for Boca Raton’s HVHZ requirements adds cost), and whether the failure has caused secondary damage to adjacent framing. Our quote includes the part, installation, disposal, and a written warranty. Under Clause 1 of The Haven Standard, you receive the full price in writing before we order material. No change proceeds without a signed change order. Every visit includes a documented photo record of the condition we found and the work performed.

DIY or Call Us?

An owner can safely inspect the gasket condition with a flashlight and credit card: slide the card between the sash and frame; resistance should be consistent. If it passes through freely, the gasket has compressed. Check the weep holes at the sill for obstruction; a pipe cleaner clears most blockages. What you should not attempt: removing a fixed glass panel (weight exceeds 150 pounds on most ViewLux units), adjusting the roller carriage (spring tension can release suddenly), or resealing the sill pan (the end-dam must integrate with the WRB behind the siding, and improper sequencing traps water). The 500 Series curtain wall is structural; altering a mullion without engineering review voids the Miami-Dade NOA. Call (754) 254-8065 and we’ll assess it without charge.
