Boral Home Additions & ADU: The West Palm Beach Owner’s Guide
If you’re researching a Boral home addition or ADU in West Palm Beach, you’re likely wondering what it actually costs and whether your existing structure can handle the expansion. For a Boral-compatible addition or ADU project in this market, expect an installed range of $45,000 to $130,000 for additions and $90,000 to $220,000 for a full ADU build, depending on square footage, foundation conditions, and finish level. Most homeowners discover this page because they’re standing in a home that’s outgrown them, or they’re weighing the numbers on a detached unit versus a garage conversion.
The short version: we plan, permit, and build these projects with a written price before any work starts. You’ll know the number before the first shovel hits dirt, and every project carries our 365-Day Done Right Promise in writing. No surprise invoices, no scope creep, no disappearing act after the deposit clears.
Key takeaways:
- Installed addition range in West Palm Beach: $45,000 – $130,000; ADU construction: $90,000 – $220,000
- Boral exterior cladding and trim products perform differently in Florida humidity and hurricane conditions than in other climates – we account for that in the plan
- Every project gets a written scope and price before work begins, with a full-year written guarantee
- Led by Curtis Lane, a contractor with three decades of field experience who’s been running jobs from Northwood Village to the western communities
Which Boral Models This Applies To
Boral manufactures a range of exterior cladding, trim, and siding products commonly specified on West Palm Beach additions and ADUs. The projects we take on typically involve Boral TruExterior trim boards, Boral Versetta Stone cladding, or Boral roof tile systems already present on the existing structure. The key compatibility issue we see is matching new Boral products to older Boral products on the same roofline or wall plane, because profile dimensions and color batches have shifted over the years.
How to identify what you have: look for the Boral stamp or label on the backside of a removed trim piece, or check the original building plans if they’re still around. TruExterior trim boards come in standard dimensions (1×4, 1×6, 1×8, and 5/4 board profiles), and matching the exact profile matters more than matching the brand name. We stock the common TruExterior profiles on the truck for repair ties during addition work, and we source Versetta Stone and Boral tile through our documented supplier network so the spec is traceable. A note on aftermarket versus OEM: for trim and cladding, generic PVC boards are not a like-for-like swap. Boral TruExterior is a poly-ash product that behaves differently than vinyl or fiber cement in direct sun and high humidity, and cutting corners here shows up as warping and joint failure within two or three Florida summers.
We are an independent contractor serving West Palm Beach – not affiliated with Boral, but we work with their products on a regular basis and we know which specifications hold up in this climate.
Styles & brands we work with
Signs Your Boral Home Additions & ADU Materials Are Failing
- Trim boards pulling away at corners and joints. Florida’s wet-dry cycle plus direct sun causes expansion and contraction. If the original installer used the wrong fasteners or no expansion gap, the boards will cup and pull. This is the most common failure we see on five-to-ten-year-old Boral trim installations.
- Caulk failing along window and door trim within a year of application. That’s usually a substrate problem, not a caulk problem. If the sheathing behind the trim wasn’t flashed properly, moisture gets behind the board and pushes the sealant out. Re-caulking alone won’t fix it.
- Visible swelling or soft spots where trim meets the roofline. This typically means water is getting in behind the fascia or soffit, and by the time you can press it with a finger, the substrate is already compromised.
- Stone cladding pieces loosening or shedding at the bottom course. Versetta Stone is a mechanically fastened system, but if the starter strip wasn’t level or the fasteners missed the nailing flange, you’ll see movement first at the base. In West Palm Beach’s sandy soil, any settling in the foundation amplifies this.
- Roof tiles cracking or sliding after a storm. Boral concrete tile is heavy and durable, but improper underlayment installation means tiles can shift even when the tile itself is fine. After any significant wind event, a visual check from the ground is worth doing.
Replacement Cost & What’s Included
For a complete Boral home addition in West Palm Beach, the installed cost typically lands between $45,000 and $130,000. A detached Boral-clad ADU runs $90,000 to $220,000, with the spread driven by square footage, site preparation, foundation type, and interior finish level. A garage conversion using compatible Boral trim on the exterior falls between $30,000 and $80,000.
What drives the range on a West Palm Beach project more than anything is the foundation and the wind-load requirements. If the soil on your lot is loose sand (common west of I-95), the footer has to go deeper and wider. If your addition changes the roofline, you’re into hurricane-strapping territory, and the inspection timeline gets longer. None of this is guesswork for us. Curtis Lane has been building here long enough that he knows what the inspector will flag before the plans go in.
Every line-item quote we write includes materials, labor, permits, and disposal. You’ll see the Boral products itemized by SKU where applicable, so you can verify what you’re paying for. The 365-Day Done Right Promise covers the workmanship for a full year: if the addition or ADU fails inside that window, we come back and correct it at no charge. That’s in writing before we start.

If you have a loose trim board or a visible gap at a joint, you can safely document it with photos and measurements before calling us. That helps us bring the right materials on the first trip. What you should not do is start pulling trim boards or removing cladding to “see what’s behind it.” Once you open the wall cavity, you’ve created a new opening that needs immediate weatherproofing, and in West Palm Beach’s afternoon downpours, that’s how a $200 trim repair becomes a $4,000 water damage claim.
For anything involving rooflines, elevated work, or structural connections, this is not a weekend project. High-ladder work and hurricane-strap installation belong in the hands of someone who does it every week and carries the insurance to back it up. If you’re not sure which category you’re in, call us at (728) 203-9809 and describe what you’re seeing. We’ll tell you straight whether it needs a crew or just a caulking tube.
Straight number, full scope, no surprises after the invoice.
FAQs
A properly installed Boral addition with TruExterior trim should last 30 to 40 years before major exterior work is needed, with re-painting or re-caulking every 7 to 10 years depending on sun exposure. The lifespan killer in this market is water intrusion at flashing points, which is why we spend more time on flashing details than on the visible finish work. Call (728) 203-9809 to have us take a look at your existing conditions.
Yes, if the damage is isolated to one board and the substrate behind it is dry and sound, a single-board replacement is straightforward and usually costs a few hundred dollars in labor and material. If multiple boards are failing or the moisture has gotten into the sheathing, you’re looking at a larger repair. We’ll tell you which one you have when we see it.
A simple single-room addition typically takes 10 to 16 weeks from permit approval to final walkthrough; a full ADU can run 5 to 8 months depending on foundation work, utility connections, and inspection scheduling in West Palm Beach. We give you a schedule in writing with the quote, and we call you before anything changes
