Caesarstone Home Additions & ADU: The West Palm Beach Owner’s Guide
Home additions and ADUs built around Caesarstone surfaces in West Palm Beach typically run $45,000 to $130,000 installed, depending on square footage, foundation work, and whether you’re adding a full kitchen with the Caesarstone counters or a simpler living space. We stock Caesarstone-compatible materials and can usually get your project quoted within a few days of the site walk. Most owners discover they need this page when an existing addition is failing at the seams, the slab has cracked from slab settlement, or they’re planning an ADU and want the Caesarstone specified correctly from the first pour.
What you’ll find here: which Caesarstone applications hold up in South Florida humidity, what fails first, what a realistic budget looks like in West Palm Beach, and when you’re better off calling us than swinging a hammer yourself. Curtis Lane has been running additions and ADUs in West Palm Beach for years, including work along the Northwood Village corridor, and he’s seen every way a Florida addition goes wrong.
Which Caesarstone Applications This Applies To
Caesarstone isn’t a single product line. It’s a quartz surface manufactured in specific thicknesses, typically 2cm (3/4″) and 3cm (1-1/4″), and the thickness you spec changes how the substrate gets built. In an addition or ADU, Caesarstone most often shows up as kitchen countertops, bathroom vanities, wet bars, and outdoor kitchen tops. Outdoor applications are where we see the most confusion in West Palm Beach, because not every Caesarstone color is rated for direct sun and rain exposure.
Here’s the compatibility gotcha most homeowners miss: Caesarstone’s outdoor-approved colors are limited, and using an interior color outdoors in Florida heat will cause the resin to yellow and the slab to warp at the seams within a few years. Before you spec Caesarstone for that covered lanai or outdoor kitchen, confirm the color is on their exterior list. If you’re matching an existing indoor Caesarstone top in your addition, check the underside of the slab for the production label. That label tells us the color code, batch, and thickness so any new piece matches in both dimension and finish.
On the OEM versus aftermarket question: for Caesarstone specifically, we always source through authorized distribution. Quartz isn’t like a faucet cartridge where a third-party part is functionally identical. The color, veining pattern, and finish are proprietary, and a knockoff slab never matches at the seam. For supporting materials like substrates, adhesives, and edging, we use commercial-grade products rated for quartz weight and Florida moisture, not whatever is cheapest at the big box store.

Signs Your Home Addition or ADU Is Failing
- Caesarstone seams pulling apart or cracking. This usually means the substrate below is flexing or the slab was installed without proper support at the overhang. In West Palm Beach, slab settlement from sandy soil is the most common culprit for movement.
- Doors and windows sticking in the addition. That’s settlement, not humidity. When the foundation shifts unevenly, openings rack out of square, and the fix means addressing what’s underneath, not planing the door.
- Drywall cracks at corners and above headers. Some hairline cracking is normal as a new addition settles, but recurring cracks that reopen after patching point to a structural or moisture problem that needs a real look.
- Musty smell or visible mold at the base of walls. Florida additions without proper vapor barrier and drainage details wick moisture up from the slab. This is a construction problem, not a cleaning problem.
- Electrical issues: breakers tripping, lights flickering. Undersized panels or improper rough-in work in an ADU can overload circuits. This is a safety issue and needs a licensed fix, not a reset button.
Replacement Cost & What’s Included
In West Palm Beach, a home addition runs $45,000 to $130,000, and an ADU construction project runs $90,000 to $220,000. The spread comes down to square footage, whether you’re adding a bathroom or kitchen with Caesarstone surfaces, foundation type, and how much electrical and plumbing rough-in is required. A garage conversion lands between $30,000 and $80,000, which is often the fastest path to an ADU when the existing structure is sound.
Every number we give is a written price before any work starts. That includes permits, materials, labor, and the Caesarstone fabrication and installation if it’s part of the scope. We don’t do change orders at the door. If we find something in the field that changes the number, Curtis calls you before we touch it.
Here’s the cost breakdown most West Palm Beach owners ask about:
- Home addition: $45,000 – $130,000
- ADU construction: $90,000 – $220,000
- Garage conversion: $30,000 – $80,000
- Countertop installation (Caesarstone): $2,000 – $6,500
- Kitchen island installation: $3,000 – $10,000
All completed work carries the 365-Day Done Right Promise. If the addition or ADU fails within the first year, we come back and correct it at no charge. That’s in writing, in your hand, before the final walkthrough.
DIY or Call Us?
You can check a few things yourself: look for visible cracks in the Caesarstone at seams, feel for soft spots in the floor, and note any doors that don’t close square. That information helps us on the first call.
What you should not do is open up walls, touch electrical panels, or try to level a settling slab. Framing, electrical, plumbing, and foundation work on an addition or ADU in West Palm Beach carries real risk: live circuits, load-bearing walls, and the Florida-specific hurricane-strapping requirements that an inspector will check. Getting the rough-in wrong means tearing finished work out later, and that’s the most expensive mistake you can make on an addition.
If you suspect the addition is failing or you’re planning a new one with Caesarstone surfaces, call us at (728) 203-9809. We’ll walk the site, tell you what’s actually wrong, and give you a written number before anything starts.

AfterCan a failing addition be repaired instead of rebuilt?
Yes, in most cases, a failing addition can be repaired without tearing the whole structure down. The repair scope depends on what failed: slab settlement gets addressed with underpinning or piers, framing issues get corrected at the load points, and Caesarstone seams can be refilled and re-polished. Call (728) 203-9809 and we’ll tell you what’s repairable and what isn’t, with a written price either way.
How long does an ADU or addition project take in West Palm Beach?
A garage conversion typically takes 8 to 12 weeks, while a new detached ADU runs 4 to 8 months depending on permitting and foundation work. West Palm Beach inspection timelines move at their own pace, and we schedule around them rather than promising dates we can’t keep. We’ll give you a written schedule with the written price.
Do you stock Caesarstone materials locally or order per project?
We order Caesarstone slabs per project through authorized distribution, matched by color code and batch to any existing surfaces, because quartz colors are proprietary and need to match at the seam. For the structural side of the work, we keep common framing, substrate, and fastening materials on hand. We also work regularly with KraftMaid, Cambria, and Silestone when an owner wants alternatives, but the spec gets settled before we write the number.
FAQs
A properly installed indoor Caesarstone countertop should last 20+ years in a West Palm Beach home, but outdoor applications in direct Florida sun can fail in 5 to 10 years if the wrong color is used. The substrate matters as much as the slab, a flexing base will crack the quartz no matter how good the stone is. Call (728) 203-9809 for an evaluation if you’re seeing cracks or seam separation.
No, the written price we give you before work begins is the price, unless we discover a condition in the field that could not have been seen during the estimate. If that happens, Curtis calls you before we touch anything, explains what we found, and gets your sign-off before proceeding. That’s The Garrison Standard: straight number, full scope, no surprises after the invoice.
Yes, we pull all required permits for additions, ADUs, and garage conversions in West Palm Beach, and we coordinate the inspections. Permits are included in the written price, not added as a surprise line item at the end. A permitted project is the only kind that protects your property value and your insurance.
A straight Caesarstone countertop replacement inside an existing addition usually takes one day for fabrication and one day for installation, assuming the substrate is sound. If the substrate needs work, that gets addressed first and the schedule gets extended. Call (728) 203-9809 and we’ll give you a real timeline with the written estimate.
