Cambria Home Additions & ADU Nationwide

Cambria Home Additions & ADU: The Fort Lauderdale Owner’s Guide

Cambria quartz surfaces in Fort Lauderdale home additions and ADUs typically run $2,000-$6,500 installed for countertops, with full addition projects ranging $45,000-$130,000 depending on square footage and structural work. We stock Cambria slabs in standard thicknesses and keep compatible edge profiles, adhesives, and seam kits on hand for same-day templating in Fort Lauderdale. Most owners discover their Cambria surface is failing when hairline cracks appear near cooktop cutouts, seams lift in the humidity, or the original installer used a non-Cambria-approved substrate that has begun to telegraph through.

Which Cambria Models This Applies To

Cambria’s residential line breaks into two categories relevant to Fort Lauderdale additions and ADUs: the standard 1.2 cm and 2 cm slabs, and the thicker 3 cm profiles used for waterfall islands and integrated backsplashes. The model name is printed on the original invoice or etched on the underside of removable sections; if that’s gone, measure thickness at an exposed edge and photograph the pattern against Cambria’s online gallery. We’ve matched everything from the Brittanicca series common in Victoria Park renovations to the simpler Windermere used in garage conversions near Coral Ridge.

The OEM-versus-aftermarket question for Cambria is straightforward: Cambria does not license third-party slab manufacturing, so “aftermarket Cambria” is either remnant stock, mislabeled competitive quartz, or a fabricator’s attempt to color-match with Silestone or Caesarstone. We source through Cambria’s authorized Fort Lauderdale distributor, which means the slab serial number traces back to the Le Sueur, Minnesota plant and carries the full lifetime warranty. Remnants can save 30-40% on small ADU kitchens but limit pattern selection and void the transferable warranty.

Signs Your Cambria Home Additions & ADU Is Failing

• Hairline cracks radiating from sink or cooktop cutouts. Cambria is engineered quartz, not stone, but thermal shock from a gas cooktop installed too close to the edge or an undermount sink without proper support creates stress fractures. In Fort Lauderdale, we see this most often in additions where the original contractor sized the cutout with a standard template rather than the cooktop manufacturer’s spec.
• Visible seam separation or lippage. Humidity cycling in non-climate-controlled ADUs during construction causes the substrate to expand and contract; if the installer used a rigid epoxy instead of Cambria’s specified flexible adhesive, the seam opens. We’ve reseamed kitchens in Rio Vista where the gap had grown to a quarter-inch.
• Dull or etched surface that won’t polish back. Cambria is non-porous and acid-resistant, but repeated exposure to pool chemicals, certain grout haze removers, or abrasive scrub pads degrades the resin binder. The surface isn’t stained; the finish is mechanically worn, and no topical product restores it.
• Substrate telegraphing, visible as ripples or hollow spots. This happens when the original installer skipped the full-coverage plywood underlayment or used particleboard in a humid environment. You tap the surface and hear the difference; the Cambria itself is intact, but it’s flexing over voids.
• Water intrusion at the backsplash seam. In Fort Lauderdale’s driving rains, an ADU with a compromised window seal can direct water behind the counter. If the silicone bead at the wall joint has failed, water wicks into the cabinet box, not the Cambria, but the swelling substrate pushes the quartz up from below.

Replacement Cost & What’s Included

For Fort Lauderdale, Cambria countertop replacement in a home addition or ADU kitchen runs $2,000-$6,500 installed, with the full addition project at $45,000-$130,000. The spread depends on three factors: slab grade (Cambria’s designs tier by pattern complexity), linear footage of edge work (a simple eased edge versus a double ogee or waterfall return), and whether we need to remove and replace the existing sink and cooktop or work around them.

Our quote is flat and written, delivered before templating begins. It includes digital measurement, fabrication at our partner shop, transport, installation, sink cutout and mounting, one faucet hole, and silicone sealant. Under Clause 1 of the Haven Standard, that price is fixed; if we find rotted substructure during removal, we document it with photos, write a change order with the exact additional cost, and nothing proceeds until you sign. The Cambria slab carries the manufacturer’s lifetime warranty; our installation workmanship is covered by the 365-Day Done Right Promise.

DIY or Call Us?

There’s a safe middle ground here. An owner can verify the slab thickness, photograph the pattern for identification, and check for obvious substrate issues by tapping the surface with a plastic mallet to listen for hollow spots. What you cannot safely do is remove a Cambria countertop yourself. The material weighs 20 pounds per square foot at 3 cm thickness; a typical ADU kitchen section is 400-plus pounds, and the adhesive bond to the substrate requires controlled release with specialized tools. We’ve seen cracked cabinets, torn drywall, and one instance in Fort Lauderdale where a homeowner dropped a section on a tile floor.

Measure twice, write it down, then say it once. Call us at (754) 254-7676 and we’ll template, source the correct Cambria series, and install with the substrate prep the original job may have skipped.
