Cambria Home Additions & ADU: The West Palm Beach Owner’s Guide
If you’re planning a home addition or ADU in West Palm Beach that will use Cambria quartz surfaces, the installed cost typically runs $45,000 – $130,000 for the full project, with Cambria countertops, backsplashes, and island tops adding $2,000 – $6,500 depending on square footage and edge profile. We stock Cambria quartz in standard and jumbo slab formats and install it on additions and ADUs throughout Palm Beach County. Most homeowners don’t discover a problem with their Cambria product until the substrate underneath fails: a seam opens, a corner chips, or the overhang starts to deflect because the framing settled in our sandy, high-water-table soil.
That’s the thing about Cambria in South Florida: the quartz itself is dense and non-porous, but it does not forgive a bad installation. If the cabinet boxes or the subfloor moved after the fact, cracks and seam separation show up fast. Brad Remodeling fixes it right, with the substrate corrected first.
Key takeaways:
- Cambria surfaces in West Palm Beach additions and ADUs cost $2,000 – $6,500 for the countertop portion alone.
- The full home addition runs $45,000 – $130,000; a detached ADU runs higher at $90,000 – $220,000 due to separate utilities and foundation work.
- We write the price down before the first tool comes out and we stand behind every installation for one full year under the 365-Day Done Right Promise.
Which Cambria Models This Applies To
Cambria doesn’t organize its lineup by “models” the way an appliance maker does. It’s organized by design series and slab format. The current Cambria catalog includes over 130 designs grouped into collections like the Coastal Collection, Marble Collection, Classic Collection, and the newer Inverness and Summerhill series. Each design is available in either standard slab size (roughly 55.5 inches by 122 inches) or jumbo slab size (up to 65.5 inches by 132 inches). Here’s the compatibility gotcha most West Palm Beach homeowners hit: if your island or peninsula runs longer than about 10 feet, you need the jumbo slab, and not every Cambria design is produced in jumbo format. You find the design name on the slab label affixed to the back side or on the paperwork from your original fabricator. A label that just says “Cambria” without a design name means you’ll need to match the veining pattern visually or go with a complementary design.
For home additions and ADUs, we specify Cambria in 2 cm or 3 cm thickness. The 3 cm is what we recommend for kitchen islands and bathroom vanities because it carries a full overhang without needing a plywood subtop. For vertical applications like shower walls or backsplashes, 2 cm is standard and keeps the weight manageable on wood-framed addition walls. We also install Silestone and Caesarstone when a homeowner wants a different manufacturer, but Cambria’s zero-resin-binder, 93% quartz makeup handles our humidity without the clouding you sometimes see in lower-grade engineered stone.
We are an independent installer and are not affiliated with Cambria or its distributors. That independence means we match the material to the job, not to an inventory surplus.
Styles & brands we work with
Signs Your Cambria Home Additions & ADU Is Failing
- Seam separation or a visible glue line at the joint. This almost always traces back to substrate movement beneath the slab. In West Palm Beach, the sandy soil and seasonal moisture swings mean a slab-on-grade addition can shift a quarter inch without you noticing anything except the seam pulling apart.
- A hairline crack running from a sink cutout or a cooktop cutout. Cambria is hard, but the corners of a cutout are stress risers. If the cabinet below isn’t shimmed dead level, the slab flexes at the narrowest point and eventually cracks.
- Island or peninsula overhang that visibly bounces when you lean on it. That’s a missing or undersized support bracket. Cambria’s published overhang limits are 14 inches unsupported for 3 cm material, less for 2 cm. Beyond that, you need corbels, steel brackets, or legs.
- Chipped or rough edge where it wasn’t before. Edge chips happen when someone knocks a heavy pot or ladder against the edge, but they also happen when the original fabricator left a microfracture during cutting. Once moisture gets into the microcrack, thermal cycling finishes the job.
- Discoloration or “clouding” that doesn’t wipe off. This isn’t a Cambria failure; it’s usually hard-water mineral buildup or cleaner residue. If the surface was sealed with a topical sealer it didn’t need, the sealer film breaks down unevenly and looks hazy. Cambria requires no sealing, and most cleaners sold for “stone care” will leave a film on it.
Replacement Cost & What’s Included
For a Cambria surface replacement within an existing West Palm Beach addition or ADU, you’re looking at $2,000 – $6,500 installed. A small bathroom vanity top might run $800 – $1,200. A full kitchen with an island, waterfall edge, and extended breakfast bar hits the upper end. What drives the price: slab format (standard vs jumbo), edge profile, number of seams, and whether we’re repairing or replacing the substrate underneath.
| Scope | Installed Price Range |
|---|---|
| Bathroom vanity top (Cambria, 3 cm) | $800 – $2,500 |
| Kitchen countertop only (standard slab) | $2,000 – $4,500 |
| Kitchen with island + breakfast bar | $3,000 – $6,500 |
| Full ADU kitchen + bath surfaces | $4,500 – $9,000 |
Every quote from Brad Remodeling includes the slab, fabrication, delivery, install, seam work, and substrate correction with the written price upfront. We pull permits where required for the addition or ADU itself. No numbers move at the door. The 365-Day Done Right Promise covers the entire installation: if the Cambria top fails inside a year, we return and fix it at no charge.

You can safely check a few things yourself: run a level across the surface, look under the overhang for missing brackets, and note where any seam separation starts. But Cambria slabs weigh roughly 13 pounds per square foot. A standard island top is 150 to 300 pounds and needs to be set without twisting, or it will crack before it ever sees a coffee mug. Moving it without damaging the cabinet boxes below, the backslash behind it, or your own back is not a weekend project. Also, lifting a slab to inspect the substrate voids your warranty with most fabricators and, more importantly, leaves you right back where you started: with a cracked top and a cabinet frame that now has pry-bar marks on it.
Call us at (728) 203-9809 and we’ll send out a background-checked, uniformed technician to measure, inspect the substrate, and give you a written price before any work begins.
FAQs
Cambria carries a lifetime warranty from the manufacturer, and in Florida’s humidity it should outlast the cabinets beneath it. What shortens its service life is never the quartz itself; it’s substrate movement, improper overhang support, or thermal stress at cutout corners from direct sun on an unshaded kitchen window.
Small chips can be filled and polished by a fabricator, but a crack running through the slab is a structural failure and cannot be reliably repaired. The crack will continue to propagate because the slab is still under load at that point. Call (728) 203-9809 for an exact assessment, and we’ll tell you straight whether it’s repairable or a replacement.
A standard countertop replacement runs two visits: template and measurement on the first, fabrication in between, and install on the second. The full process typically runs 5 to 10 business days. The install itself is usually a single morning or afternoon.
We order Cambria slabs per project from local Palm Beach County distributors, which means your slab is matched to your design and not pulled from aging inventory. We also work with KraftMaid for the cabinet boxes, Kohler for the fixtures, and Silestone when a homeowner prefers that brand.
