Cambria Home Additions & ADU: The Woodland Hills Owner’s Guide
If you have a Cambria surface in a home addition or ADU project that’s failing, cracked, or was cut wrong, we can match it, set it, and finish the job. In Woodland Hills, a full home addition runs $45,000 to $130,000, while a complete ADU construction lands between $90,000 and $220,000. The Cambria-specific portion, countertops for kitchens, baths, or wet bars inside that new square footage, typically falls in the $2,000 to $6,500 installed range depending on square footage and edge profile.
Most owners figure out there’s a problem with their Cambria surface mid-project or a few years in: a seam opens up, a corner chips at a doorway, or the first contractor measured wrong and now a slab doesn’t sit right against the wall. What stings worse than the crack is finding out the original installer won’t return the call. That’s the part of the job we handle differently.
Which Cambria Models This Applies To
Cambria runs a broad catalog, and Woodland Hills homes tend toward specific collections. We regularly see Brittanicca, Torquay, Ella, and Portrush in kitchen additions, with darker finishes like Charlestown and Berwyn showing up in ADU kitchens. The quartz itself is consistent across all Cambria designs, what changes between series is thickness and finish. The main compatibility questions are whether the slab is 2 cm or 3 cm, whether the finish is matte or gloss, and what edge profile was cut. The 6 cm laminated edge profile is common on islands, and that matters when you’re matching a replacement piece.
OEM Cambria slabs are ordered through a certified fabricator, which means the chain goes Cambria, then fabricator, then installer. Sawyer Remodel Woodland Hills is an independent contractor, not affiliated with Cambria, but we work directly with their certified fabricators in the Los Angeles area, so sourcing a replacement slab from the same quarry batch is doable, though not guaranteed on older colors. On quality aftermarket equivalents: for Cambria specifically, a close-match aftermarket quartz rarely looks right at the seam. The mineral patterns are complex enough that a close match from a different manufacturer reads as off. With Cambria, the realistic split is this: replace the full run with a new Cambria slab, or if the damage is a chip, repair with a color-matched resin and accept it won’t be invisible.
If you don’t know which color you have, order documents from your original remodel, a leftover sink cutout, or even a photo beside a piece of white paper in daylight usually gets us there. The model ID on Cambria packaging is printed on the slab sticker, but years after install most folks don’t have that. We can identify most popular Cambria colors from a phone photo.

Signs Your Cambria Home Additions & ADU Is Failing
- Crack near a corner or inside corner cutout. Cambria is durable but inside-corner cuts at sinks and cooktops concentrate stress. A hairline crack there usually means a radius was cut too tight or the slab wasn’t supported evenly underneath.
- Opened seam at the countertop joint. Woodland Hills sits against the Santa Monica Mountains, and seasonal temperature swings expand and contract stone. If the seam filler was mixed too rigid or the seam wasn’t shimmed level, it separates. That’s a fabricator issue, not a material failure.
- Chipping along a high-traffic edge. Islands and peninsula overhangs take barstool hits and dish drops. The gloss edge profile is more visible when it chips, but both finishes can do it. It’s repairable if the chip is under two inches.
- Slab movement or a hollow sound under the surface. If the slab rocks slightly or sounds hollow in spots, the adhesive bond has broken or the substrate warped. Left alone, that movement is what eventually cracks the slab.
- Staining around the sink or faucet holes. Quartz is non-porous, and Cambria stains less than granite, but hard water in the West Valley can build mineral films. If a sealant or leftover tape residue was never cleaned properly, it leaves a shadow that looks like a stain but sits on top of the finish.

AfterReplacement Cost & What’s Included
For Woodland Hills homeowners, the Cambria-related line items depend on whether you’re replacing a failed slab or finishing a new addition or ADU. A countertop install alone, including Cambria material, fabrication, delivery, and installation, runs $2,000 to $6,500 depending on the length, thickness, edge profile, and whether you need a seam. If the failure is a single island top, you’re usually in the $3,000 to $10,000 range when you include removal of the existing top and the new fabrication. The full addition cost covers everything from foundation to finish: plans, permits, framing, drywall, electrical, plumbing, flooring, and the Cambria surfaces inside.
What drives the wide range is rarely the quartz itself. It’s whether the addition needs foundation work, whether the ADU is a conversion or new build, and what the access to your property looks like. A hillside lot above Topanga Canyon Boulevard with tight access costs more than a flat Warner Center lot because material handling and crane placement get harder. What you get from us is a written price before work starts, the slab laid out for your approval before cutting, and a one-year Done Right Promise on the entire job. If something isn’t right, we fix it, and it’s in writing.
DIY or Call Us?
There are things worth checking yourself, and there are things that will cost you more the moment you touch them. You can clean the surface with a non-abrasive quartz cleaner, photograph the damage from a couple of angles, and check whether the slab moves when you lean on it. You cannot re-cut a Cambria slab in a garage. The resin binders in quartz dull standard blades, the dust is silica-heavy and bad for your lungs, and a slipped cut on a $4,000 slab is a mistake you can’t unmake. Matching seams and edge profiles takes a fabricator’s CNC setup and a steady hand on install day.
If the damage is cosmetic and small, a repair might hold. If it’s structural, a crack running through the slab or a top that’s shifted, the right move is a replacement. Call (341) 217-2776 and send us a photo. We’ll tell you honestly whether it’s repairable and what a replacement costs, before you spend a dime.
FAQs
Cambria quartz is warrantied by the manufacturer for a lifetime for residential use, and in practice the slab itself rarely fails on its own. The typical failure point is the installation: seams opening, adhesive breaking down, or edge chipping from impact. In the West Valley’s temperature swings, a properly installed Cambria top should look the same at year 15 as it did on install day.
A small chip or a minor seam separation can be color-filled and blended by a fabricator, though the repair won’t be invisible. A crack that runs through the slab’s full depth or extends from a cutout means the structural integrity is gone and the right fix is replacement. If you’re unsure, call (341) 217-2776 and we’ll look at photos before you commit to anything.
A standard countertop replacement in Woodland Hills takes about two weeks from template to install: a week for fabrication after templating, plus delivery and a half-day install. For a full addition or ADU with Cambria surfaces throughout, the kitchen and bath counters happen in the final two to three weeks of the project, not at the start.
We don’t keep Cambria slabs sitting in a warehouse, because each job is cut to a template and no two kitchens are the same. What we do stock is the supporting hardware: sink clips, seam adhesive, seam filler in Cambria’s most-used color families, shims, and undermount sink brackets. That means most installations and repairs don’t stall waiting for a small part. We also work with KraftMaid for cabinetry, Silestone for quartz, and Kohler for fixtures when a job calls for a different material route.
No. The price we put in writing is the price you approve, and the number on the final invoice is the same one. If we open a wall and find a problem we couldn’t see, like termite damage or a bowed wall that changes the countertop run, we stop, show you photos, and give you a new written price before any change happens. You decide, not us. For an exact quote on your addition or ADU, call (341) 217-2776; estimates are free.
