PGT Home Additions & ADU: The West Palm Beach Owner’s Guide
Bradford Remodeling Co West Palm Beach installs and services PGT-compatible home additions and ADUs across West Palm Beach, with most projects landing between $45,000 and $130,000 depending on square footage, foundation work, and finish level. We stock the common PGT window and door components needed for these builds, and we can typically have a crew on-site within days, not weeks. Most owners call us when an existing addition starts showing its age: a PGT sliding door that no longer seals, a window flange pulling loose from the stucco, or an ADU that never quite got finished by the last contractor.
Straight number, full scope, no surprises after the invoice.
Which PGT Models This Applies To
PGT’s product lines show up in West Palm Beach additions more than any other brand, mainly because their impact-rated windows and doors meet Miami-Dade and Florida Building Code requirements that other manufacturers don’t always hit. The Vinyl 770 and 2200 series windows are common in older additions, while the WinGuard and SpectraGuard lines dominate newer ADU construction. If you’re unsure what you have, look for the PGT label on the interior frame edge or the glass corner etching, which lists the series, manufacturing date, and impact rating. That label matters because PGT changed frame profiles across series, and a window from the 770 line will not accept hardware from the SpectraGuard line without modification.
Bradford Remodeling Co West Palm Beach is an independent service provider, not affiliated with PGT. That said, we order PGT OEM parts directly through authorized distribution channels because their frame extrusions and glass packages are not reliably interchangeable with generic aftermarket components. We’ve seen too many West Palm Beach additions where someone fished a generic roller or sash balance out of a supply house bin and ended up with a window that binds after one humid season. For structural pieces, laminated glass, and impact-rated doors, we specify OEM. For hardware that PGT sources from third parties anyway, like certain locks and rollers, we’ll use the same brand-name equivalent when it’s genuinely identical and in stock.
Styles & brands we work with
Signs Your PGT Home Additions & ADU Is Failing
- Sliding glass door drags or jumps the track. The roller assemblies on PGT sliders wear unevenly in sandy coastal air, and once the door sits off-level, the lock stile starts chewing into the frame. Left alone, you’ll eventually need a new door panel, not just new rollers.
- Condensation between the glass panes. That’s a failed seal on an insulated unit. PGT’s impact laminated glass is bonded as a single unit, so the whole panel gets replaced, not just the sash. West Palm Beach humidity makes this failure mode show up faster here than inland.
- Window or door won’t latch square. Frame settlement in an addition or ADU, especially on new fill or expansive soil common in parts of West Palm Beach, shifts the rough opening. The PGT product may be fine; the framing around it needs shimming and re-flashing before the unit gets reset.
- Water staining at the corners of sliding doors or windows. PGT frames drain through weep holes, and those clog with pollen, stucco dust, and salt residue. When water backs up, it finds the interior. Usually the fix is a full removal, cleaning, re-flashing, and reinstallation, not a caulk bead.
- Single-hung windows sliding down on their own. The block-and-tackle balance assemblies on PGT hung windows lose tension after years of UV exposure. One failing balance puts strain on the other, and you’ll feel the sash drift when you let go. We replace balances in pairs, always.

AfterReplacement Cost & What’s Included
For a PGT home addition or ADU in West Palm Beach, expect $45,000 to $130,000 for a full project with permitted drawings, foundation, framing, and finishes. If the scope is a partial repair to an existing addition, like replacing a PGT sliding door and re-flashing adjacent stucco, that typically lands between $3,000 and $9,000 depending on unit size and framing condition. An ADU built from the slab up commonly runs $90,000 to $220,000 when plumbing, electrical, and hurricane-strapping are done to code. Every quote we hand you is a written price before any work starts, with no numbers that move at the door.
What drives the range: concrete and rebar costs, the PGT window and door package you choose, whether the existing slab is salvageable, and what the inspection office requires for wind-load anchoring in your neighborhood. The written estimate you receive from us itemizes labor, materials, permits, and the PGT components by name. After the job closes, the 365-Day Done Right Promise applies: if anything we installed doesn’t hold, we come back and correct it at no charge inside a full year.
DIY or Call Us?
For a sliding door roller replacement on a ground-level PGT unit, a capable homeowner can attempt it. We won’t pretend otherwise. The danger with additions and ADUs isn’t in swapping a roller; it’s in the things you can’t see until the unit is out. In West Palm Beach, load-bearing walls in additions are often holding up hurricane-strapped roof assemblies, and an impact-rated PGT window is structural. If you pull a window or door on an exterior wall without bracing the header and re-flashing to code, you’ve created a water intrusion path and a wind-load failure waiting for the next storm. That’s not a handyman job, and it’s genuinely unsafe to attempt on a second-story opening.
What an owner can safely check: clean the tracks, clear the weep holes, and confirm whether the label says PGT WinGuard or SpectraGuard before you call. What you should not do: pull a window frame, touch any fasteners driven through the frame into the studs, or try to realign a door by grinding the track. For all of that, call (728) 203-9809 and we’ll handle it.
FAQs
A PGT impact-rated window or door in West Palm Beach typically lasts 15 to 25 years before seals fail or hardware wears out, though the salt air and direct coastal sun we get here can shorten that window on west-facing elevations. The glass itself rarely breaks; it’s the seals, rollers, and balances that go first. If your PGT units are past 15 years and showing any of the failure signs above, call (728) 203-9809 for an honest assessment and a written estimate.
Rollers, balances, locks, and weatherstripping on PGT units can usually be repaired or replaced, and we stock the common hardware on our trucks. A failed insulated glass seal or a warped frame generally means the full unit gets replaced, because PGT laminates impact glass as a single assembly. We’ll tell you which camp your unit falls into before you spend a dollar, and the written price stays fixed.
A straightforward single PGT window or slider replacement takes one day on site, including removal, framing touch-up, re-flashing, and interior trim. A full window and door package on an ADU or addition can take three to five working days depending on opening count and stucco work. We schedule around West Palm Beach’s inspection windows so the job passes the first time, and you’ll have a clean site and a written guarantee in hand when we leave.
We stock the PGT rollers, balances, locks, and weep-hole covers that fail most often on West Palm Beach additions, and our trucks carry the common fasteners and flashing materials for impact-rated installations. Glass packages and full door panels are ordered per job from PGT’s authorized distribution network, which keeps the lead time short but means an exact-match unit isn’t sitting in the back of a van. Call (728) 203-9809 and we’ll tell you right then what’s on the truck and what has to be ordered.
