Silestone Home Additions & ADU: The Orlando Owner's Guide
Silestone countertop work inside a home addition or ADU in Orlando typically runs $45,000 – $130,000 for the full build, with the Silestone countertop installation itself landing between $2,000 and $6,500 depending on slab size, edge profile, and backsplash scope. We install Silestone-compatible surfaces the week the addition is ready for finishing, and we keep standard Silestone edge profiles and sink cutouts on our schedule so your project doesn't stall at the last step. Most Orlando homeowners call us after discovering their current countertop was cut wrong, cracked during the addition's settling, or sized to a template that no longer matches the new island or wet bar layout.
Which Silestone Models This Applies To
We work with the full Silestone catalog, including the Sunlit Days, Loft, and Eternal series, in both standard 2cm and 3cm slab thicknesses. The 3cm material is what we recommend for any Orlando ADU with a kitchen or wet bar because it doesn't require a plywood substrate underlay and stands up better to Florida's humidity swings. Here's the compatibility gotcha most homeowners don't know: Silestone's Suede and polished finishes cut differently at the seam, and if your original installer used a generic fabricator who didn't adjust blade speed for the finish, you'll see chipping at the edge within the first year. We match OEM Silestone slabs when a partial replacement is needed, and we'll tell you honestly when a quality aftermarket quartz from Cambria or Caesarstone makes more sense for your addition's budget. We're an independent Orlando contractor, not affiliated with Silestone, but we've installed enough of it to know exactly how it behaves in Central Florida kitchens.

Signs Your Silestone Home Additions & ADU Is Failing
- Hairline cracks running from the sink cutout. This is the #1 failure we see in Orlando additions, usually because the fabricator cut the sink opening with square corners instead of radiused ones. Sharp corners concentrate stress, and when the cabinetry settles in Florida's sandy soil, the crack forms. The fix is a new slab with properly radiused corners.
- Seam separation where the island meets the run. If your addition was built on a slab that's still curing or on fill dirt that shifts, the cabinets move slightly and the seam opens. We can re-seam with color-matched epoxy, but if the movement is ongoing, the slab needs re-leveling first.
- Chipping along the countertop edge near high-traffic corners. Silestone is engineered quartz, about 93% natural quartz by weight, and it's tough, but repeated impact from heavy pots or a dropped tool will chip the edge. A skilled fabricator can fill small chips; large chips usually mean edge replacement.
- Discoloration or etching around the faucet base. This is less common with Silestone than with natural stone, but if harsh acidic cleaners sat near the faucet deck for months, the resin binder can dull. We'll sometimes polish this out, but deep damage means slab replacement at the faucet area.
- Uneven slab where the old counter meets the new addition counter. If your addition extended the kitchen and two different installers worked at two different times, the heights rarely match. That's a template and fabrication issue, and the only real fix is recutting one side so both planes sit flush.

AfterReplacement Cost & What's Included
For a Silestone countertop replacement specific to an Orlando home addition or ADU, expect $2,000 – $6,500 installed, which includes template creation, slab fabrication, edge finishing, sink cutout, and installation labor. The range is driven by three things: slab square footage (an ADU kitchenette runs smaller than a full addition kitchen), edge profile (a simple eased edge costs less than a mitered or waterfall edge), and whether we're handling disposal of the old countertop. If your full addition or ADU is the project, the $45,000 – $130,000 build range includes framing, electrical, plumbing, drywall, flooring, and finish surfaces like Silestone counters. Every quote from us is a written number before work starts, and our 365-Day Done Right Promise covers the installation in writing. If the seam fails or the edge chips during the guarantee window, we come back and fix it at no charge.
DIY or Call Us?
Honest answer: there's very little safe DIY room on a Silestone countertop replacement. The slabs weigh roughly 15 – 20 pounds per square foot, so a standard 10-foot run can weigh over 400 pounds, and a bad lift means a cracked slab, a damaged cabinet frame, or a back injury. What you can do safely is measure your existing run, photograph the edge profile and any damage, and check whether your current slab is 2cm or 3cm by looking at the exposed edge. If you see plywood under the quartz, it's 2cm and likely needs a full replacement rather than a repair. If you want a second opinion before committing to the work, call us at (850) 427-6454. We'll talk through what you're seeing and give you a written number before anyone picks up a tool.
FAQs
Solarstone or not, a properly installed Silestone countertop should last 25+ years in Orlando, though the Florida heat and humidity mean you'll want to reseal the seams every few years and avoid leaving standing water near the sink deck. The slab itself won't fail under normal use; what fails first is almost always the installation, not the material. Call (850) 427-6454 for an exact assessment, and our estimate is free.
Small chips can be filled and polished to near-invisible, but a structural crack running from a sink cutout or corner cannot be reliably repaired because the crack will continue to propagate as the cabinets move. We'll tell you which situation you have after looking at it, and you'll only pay for work you actually need. Call (850) 427-6454 to schedule a look.
Once the slab is selected and the template is cut, the fabrication takes 5 – 10 business days, and the on-site installation usually takes one full day for a standard kitchen or ADU run. We give you a written arrival window before the install day and a written price before any work starts. Call (850) 427-6454 to get on the schedule.
We source slabs from our Orlando suppliers per project so you get the exact color, finish, and thickness you want, not whatever was left in a yard. We also work with KraftMaid cabinetry, Cambria quartz, and Kohler fixtures on additions and ADUs, so the whole finish package comes from the same coordinated plan. Estimates are free at (850) 427-6454.
