PGT Home Additions & ADU Nationwide

PGT Home Additions & ADU: The Pompano Beach Owner’s Guide

PGT-compatible home additions and ADU construction in Pompano Beach typically runs $45,000-$130,000 for standard additions and $90,000-$220,000 for detached ADUs, with written quotes delivered before any work begins. We stock and source PGT window and door systems for integration into new construction, including the impact-rated lines that meet Miami-Dade and Broward County wind-borne debris codes. Most Pompano Beach homeowners discover their existing PGT units are failing when they start planning an addition and find the original installer’s documentation missing, or when an inspector flags mismatched fenestration during the ADU permit process.

Which PGT Models This Applies To

PGT’s product lines for home additions and ADUs fall into three categories: WinGuard aluminum and vinyl impact windows and doors, EnergyVue vinyl non-impact systems, and the Legacy aluminum line used in older Pompano Beach construction from the 1990s through mid-2000s. The label you’re looking for is a white or silver sticker in the top track of sliding doors or the hinge jamb of swing doors, showing a PGT SKU starting with WGA, WGV, EV, or LGA followed by dimensional codes.

The critical compatibility gotcha in Broward County: mixing impact and non-impact PGT products on the same structural opening violates the Florida Building Code’s continuity requirement for the building envelope. We’ve seen this in Pompano Beach’s Garden Isles neighborhood, where a 2018 garage conversion used EnergyVue windows adjacent to an original WinGuard door, and the inspector red-tagged it. For additions and ADUs, we specify WinGuard or EnergyVue depending on whether the new space requires HVHZ (High Velocity Hurricane Zone) rating. OEM PGT units are our default; aftermarket equivalents exist from CWS and ESWindows, but we only spec them when the homeowner accepts that the finish match and warranty terms differ. We keep common WinGuard sizes on our supplier pull list with 48-hour turnaround to the Pompano Beach warehouse.

Signs Your PGT Home Additions & ADU Is Failing

• Visible frame separation or corner gaps. The thermal break in aluminum PGT frames degrades faster in Pompano Beach’s salt-air environment than inland Florida, and once the polyamide strip swells, the frame corners open. We measure gap progression with feeler gauges; anything over 1/16 inch means the structural integrity is compromised.
• Impact laminate delamination (milky or cloudy interlayer). WinGuard’s laminated glass uses a PVB interlayer that absorbs moisture over time. In Pompano Beach’s humidity, we’ve seen delamination accelerate in units facing the Intracoastal with no overhang protection. The glass looks fogged even when the seal is intact, and the impact rating is void.
• Operable sash won’t lock or drags in the track. PGT’s tandem roller assemblies use a nylon housing that fatigues under repeated wind pressure cycling. A sash that once moved with one finger now needs two hands; the rollers have flat-spotted or the track itself has worn from grit intrusion.
• Water intrusion at the sill during driving rain. PGT’s weep system depends on clear drain channels and proper slope. Pompano Beach’s afternoon storms test this hard. If water pools on the interior sill, the weeps are clogged with paint or the sill pan was never properly integrated with the WRB (water-resistive barrier).
• Inspector flags missing or illegible NOA (Notice of Acceptance) documentation. This isn’t a physical part failure, but it’s what stops an ADU permit cold. PGT units installed before 2010 often lack the Miami-Dade NOA sticker required for today’s permit submittals. We maintain a library of current and archived NOAs to resolve this without replacing the unit.

Replacement Cost & What’s Included

The range depends on three factors: whether the existing opening needs structural modification for a larger or smaller unit, the finish grade (white vinyl vs. custom aluminum paint match), and whether the original installer’s flashing details were done to code or need complete rework. We itemize every line in the written quote. Under Clause 1 of the Haven Standard, that price is fixed; no change proceeds without a signed change order. Our 365-Day Done Right Promise covers the installation and integration work, and PGT’s own warranty runs 10 years on glass, lifetime on hardware.

DIY or Call Us?

There’s a short list of checks a Pompano Beach homeowner can safely make: verify the PGT label SKU, photograph any visible damage for documentation, and confirm whether the unit opens and locks smoothly. What you cannot safely assess is the structural integration, the WRB continuity, and whether the unit meets current code for a permitted addition or ADU.

DIY replacement of a PGT unit in a new addition or ADU crosses into territory where errors are expensive and permit failures are likely. The Florida Building Code’s fenestration requirements for HVHZ zones are specific about anchorage schedules, sill pan integration, and missile-impact documentation. A unit that looks correct but lacks the right NOA will fail inspection, and the rework cost typically exceeds the original install price. We measure twice, say it once, show our work, and we document every step with the photo record included standard on every visit. Call (754) 714-6540 to schedule your free estimate.
