American Standard Home Additions & ADU: The West Palm Beach Owner’s Guide
If you have an American Standard addition or ADU that’s showing its age, the fast answer is this: Bradford Remodeling Co West Palm Beach handles full American Standard-compatible home additions and ADU work in West Palm Beach, with completed projects typically landing between $45,000 and $130,000 installed, depending on square footage, foundation conditions, and finish level. We’re not the manufacturer’s parts counter. We’re a Garrison Partners remodeling firm that builds and corrects these structures to spec, and when a component of an existing American Standard-style addition fails in Florida’s heat and humidity, we’re the crew that fixes it right the first time.
Most West Palm Beach homeowners discover they have a problem the same way: a door starts binding, drywall cracks snake down a corner, or an ADU’s mini-split can’t hold temperature. The root cause is rarely the unit itself. It’s usually how the addition was tied into the existing structure, how the substrate was prepped, or how the flashing was done at the roofline. Curtis Lane has been running jobs in West Palm Beach for years, and he’ll tell you the same thing he tells every homeowner on the first walk: “Straight number, full scope, no surprises after the invoice.”
Key Takeaways
- American Standard home additions in West Palm Beach run $45,000 – $130,000 installed for full scopes; ADU construction typically runs $90,000 – $220,000.
- We diagnose the structure, not just the symptom. Failing drywall, binding doors, or humidity control problems in Florida almost always trace back to the tie-in, the vapor barrier, or the flashing.
- Every completed job carries the 365-Day Done Right Promise in writing. If it fails within a year, we return at no charge.
- Written price before any work starts. No numbers move at the door.
Which American Standard Models This Applies To
American Standard doesn’t make a single “home addition” product. What most West Palm Beach owners mean when they say they have an American Standard addition or ADU is one of two things: either the structure was built with American Standard HVAC, plumbing fixtures, and water heating inside it, or the build was specified around American Standard’s residential construction guidance and rough-in dimensions. That distinction matters because the failure mode changes.
If the American Standard components inside the addition are failing – a water heater that rusted through, a condensate line that’s clogged, a fixture set that’s leaking at the rough-in – that’s a parts-and-labor job. We match the exact model number stamped on the unit, and we install to the manufacturer’s clearance and drain specs. If the structure itself is failing – the addition is pulling away from the main house, the ADU slab is settling, the roof membrane is delaminating in Florida’s UV – that’s a rebuild scope. We still work from the original American Standard rough-in dimensions where they apply, but the fix is structural, not component-level. We also stock and install compatible parts for KraftMaid cabinetry, Cambria and Silestone surfaces, and the major fixture lines, so a failing addition doesn’t mean losing the interior you already paid for.
One compatibility gotcha we see in Florida: many “American Standard” additions built in the 1990s and early 2000s used older rough-in dimensions for plumbing and electrical that don’t match current code for ADUs in West Palm Beach. If we’re correcting a failing wall or redoing a wet area, and the rough-in is out of date, the permit office will require us to bring it current. That’s not scope creep. That’s Florida code. We tell you before we touch it.
Styles & brands we work with
Signs Your American Standard Home Addition or ADU Is Failing
- Doors that bind or won’t latch. This is usually the addition settling away from the main structure. In West Palm Beach’s sandy, limestone-heavy soil, differential settlement is common. We dig down to see whether it’s ongoing or long-stabilized before we quote.
- Drywall cracks at the corners of windows and doors, or along the tie-in seam. If the crack runs in a stair-step pattern along the seam where the addition meets the original house, that’s a framing or foundation tell, not a cosmetic problem. It’s the most common symptom of a failing addition tie-in in South Florida.
- Humidity inside the ADU that won’t come down even with the AC running. This usually means the vapor barrier was compromised, the wall cavity is open to outside air, or the conditioned envelope was never sealed properly. In West Palm Beach’s climate, a leaking envelope means mold inside walls within months, not years.
- Flashing that’s lifted, cracked, or pulling away at the roofline. The sun in Palm Beach County is brutal on roof flashing. Once water gets behind it, the roof deck and the top plates rot. By the time you see a ceiling stain, the damage usually extends a few feet in every direction.
- A slab floor that has visible cracks wider than a quarter. Hairline cracks are normal in Florida concrete. Cracks you can slide a quarter into, especially if they’re wider at one end, mean the slab is moving. It’s worth having us look before you plan any finish work on top of it.

AfterReplacement Cost & What’s Included
In West Palm Beach, a full home addition on a failing or failed structure runs $45,000 to $130,000 installed. An ADU build runs higher, typically $90,000 to $220,000, because South Florida ADU code requires separate service, separate egress, and hurricane-rated windows and doors. A garage conversion is usually $30,000 to $80,000 depending on whether the existing slab can be reused.
What drives the range, in plain terms: soil condition under the existing slab, whether the tie-in to the main house needs structural correction, how much of the existing envelope has water damage, and the level of interior finish you want. We give you a written line-item price before any work starts. That price includes the parts, the labor, the permits, the inspection coordination, and a signed 365-Day Done Right Promise in your hand when the job closes. If the work fails inside that year, we fix it at no charge. That’s what The Garrison Standard requires.
DIY or Call Us?
You can safely check a few things yourself: note where your cracks are, measure the width with a coin, check if doors are binding seasonally or permanently, and look for flashing you can see lifting from the ground. That information helps us give you a straight answer over the phone.
Here’s where DIY goes wrong on this kind of work: you can’t see what’s inside the wall without opening it, you can’t tell whether settlement is active or old without measuring over time, and you can’t pull a permit as a homeowner for structural correction in West Palm Beach on an existing addition. If you open a wall and hit a load path, you need an engineer’s letter before the city will sign off. We handle all of that. If you want the scope and the number first, call (728) 203-9809 and ask for a walkthrough. It’s free.
FAQs
A properly built addition on a good foundation with correct flashing and a sealed envelope should last 50 years or more, even in Florida’s climate. The weak points are flashing (replaced every 15 – 20 years), the vapor barrier (compromised by water intrusion long before it fails visibly), and the tie-in between new and old framing, which is where most West Palm Beach additions fail first. Call (728) 203-9809 and we’ll walk the whole structure.
Yes, most failing additions in West Palm Beach can be corrected without a full teardown. The repairs depend on what we find: lifted flashing gets replaced, rotted top plates get sistered, compromised vapor barriers get opened and resealed. If the slab is sinking, we can lift and stabilize it in many cases. The honest answer requires seeing the structure. Estimates are free.
Structural corrections on an existing addition usually run two to four weeks, depending on permit turnaround and inspection scheduling. Full rebuilds and new ADUs run two to six months. Florida’s hurricane inspection cycles can add time in the fall. You’ll get a written schedule with your written price, and we call you before anything changes, not after.
We stock the common components that fail in Florida: flashing, vapor barrier, structural ties, hurricane straps, and the hardware needed for tie-in correction. American Standard-branded fixtures and mechanicals we order by model number so you get the exact unit, not a substitute. We also work with KraftMaid, Cambria, and Silestone components when the interior needs to be matched. Call (728) 203-9809 and we’ll confirm what’s on the truck before we schedule.
