PGT Home Additions & ADU Nationwide

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

PGT-compatible window and door systems for home additions and ADU construction in Boca Raton typically run $45,000-$130,000 installed, depending on whether you’re extending an existing footprint or building a detached unit. We stock PGT WinGuard and EnergyVue series frames, impact-rated glass packages, and replacement hardware for both new construction and retrofit applications. Most PGT parts orders for active projects arrive within 24-48 hours, and our crews carry common frame extrusions and sash balances for same-day field repairs when a unit fails mid-project.

Owners usually discover a PGT part failure during the rough-in or finish phase of an addition. A window sash that won’t lock square, a sliding door roller that groans across the track, or impact glass that fogs between the panes after the first summer storm - these are the moments when a project’s timeline stalls because one component isn’t performing the way the rest of the structure demands.

Which PGT Models This Applies To

PGT builds three product tiers relevant to Boca Raton additions and ADUs, and the parts are not interchangeable between them. WinGuard is the impact-rated aluminum line required by Florida Building Code in the High-Velocity Hurricane Zone; EnergyVue is the vinyl-framed impact line that meets the same wind-borne debris standard with better thermal numbers; and the non-impact aluminum series is sometimes used for interior-facing walls in larger additions where the code allows.

To identify your series, check the etched mark in the glass corner or the label on the frame jamb. WinGuard frames measure 2-5/8 inches in depth; EnergyVue vinyl frames run 3-1/4 inches. The roller assemblies differ - WinGuard uses a stainless tandem roller rated at 125 pounds per panel, while EnergyVue rollers are polymer-bodied with a lower load rating that suits lighter vinyl sashes. We source OEM PGT hardware through their Doral distribution center, and for discontinued extrusions we machine compatible replacements from Keller or C.R. Laurence stock. The aftermarket decision depends on whether your project is active permitting (OEM required for final inspection) or a repair on an existing structure where matching function matters more than matching label.

Signs Your PGT Home Additions & ADU Is Failing

• Sash won’t lock or seal properly. The multi-point locking mechanism has slipped out of alignment, usually because the frame settled after installation or the keepers corroded in Boca Raton’s salt air. A gap at the lock side means the weatherstrip isn’t compressing, and you’ll feel it in the cooling bill before you see water intrusion.
• Sliding door resists movement or jumps the track. The tandem roller assembly has flat-spotted or the track itself has bowed from thermal expansion. In south Florida’s cycle of wet heat and dry air conditioning, aluminum track can creep 1/8 inch over a ten-foot span - enough to bind the rollers.
• Impact glass fogs between panes. The insulating glass unit (IGU) seal has failed, admitting moist air that condenses on the interior surfaces. Once the desiccant inside the spacer is saturated, the fogging becomes permanent and the impact rating is compromised because the laminated layer may delaminate.
• Frame weeps but doesn’t drain. The weep holes in the sill are clogged with construction debris or insect nests, common in Boca Raton’s sandy soils. Water ponds in the track and eventually finds the wall cavity, where it shows up as drywall staining six feet away from the window.
• Hardware operates roughly or chatters. The operator gears in a casement window have stripped, or the corrosion-resistant coating on the handle spindle has worn through. PGT uses a 5/16-inch spindle on most casement operators, but the arm geometry varies by sash size - a 24-inch sash takes a different arm reach than a 36-inch.

Replacement Cost & What’s Included

For a full PGT-equipped home addition or ADU in Boca Raton, our installed range is $45,000-$130,000. A single window replacement within an existing addition runs $800-$2,400 depending on size, impact rating, and whether the original frame can be preserved. Sliding door roller replacement is $180-$420 in labor plus parts; a full IGU replacement in an existing PGT frame is $340-$780 per unit.

What drives the range: impact-rated glass costs roughly 40% more than non-impact, and the permit path for HVHZ compliance adds inspection steps that standard zones don’t require. Our quotes itemize frame, glass, hardware, and labor separately - under Clause 1 of the Haven Standard, the price is written before anyone starts, and no change proceeds without a signed change order. Every PGT installation carries our 365-Day Done Right Promise: if the sash doesn’t seat, the lock doesn’t catch, or the weep doesn’t drain, we return and make it right. The documented photo record from your project lives in our system, so we know exactly what was installed and when.

DIY or Call Us?

There’s a safe middle ground for PGT owners, and then there’s the point where the tool in your hand becomes a liability. You can clear weep holes with a piece of wire and verify that the sill cap is seated - that’s maintenance, not repair. You can also photograph the etched glass mark and the frame label so we order the right part the first time.

What we don’t recommend: removing a fixed sash to access an IGU, adjusting multi-point lock keepers with the sash under wind load, or attempting to reset a sliding door panel that weighs 180 pounds of aluminum and laminated glass. Impact-rated units are engineered as a system; the frame, glass, and hardware are tested together. A field modification voids the rating and, in Boca Raton’s code environment, can fail inspection. We’re not affiliated with PGT - we’re an independent contractor - but we install to their spec and document the compliance chain for your permit file. Call (754) 254-8065 when the symptom is beyond weep-hole cleaning; we’ll schedule a free estimate and bring the right parts to the first visit.
