Silestone Home Additions & ADU: The Long Beach Owner’s Guide
If you’re planning a home addition or ADU in Long Beach and want Silestone surfaces in the new space, the honest price range runs $45,000 to $130,000 depending on square footage, roofline, foundation work, and how much Silestone you’re actually putting on the cabinets. We install Silestone countertops, islands, and backsplashes as part of the addition itself, using the same named-brand materials you’d research on your own. Most Long Beach homeowners discover they need this work done when a kitchen bump-out or garage conversion reaches the surface-selection stage, and they want a single contractor who can frame walls, pull permits, and finish with a Silestone product that carries its own manufacturer warranty.
Which Silestone Applications This Involves
Silestone is a quartz surface made by Cosentino, and it shows up in home additions and ADUs in three places: countertops, island tops, and backsplash material. The product lines that matter here are Silestone’s Classic, Sunlit Days, and Influencer Series, each with different slab thickness specs. The two thicknesses you’ll actually encounter in Long Beach are 2 cm and 3 cm. A 2 cm slab is lighter and typically requires a plywood substrate underneath, while a 3 cm slab can sit directly on cabinets without additional support. For a new ADU kitchen, we recommend 3 cm because the surface does the work on its own and holds up better to the temperature swings that come with an uninsulated Long Beach garage conversion. The compatibility detail most owners miss: Silestone slabs are manufactured in jumbo format, roughly 55 inches by 120 inches, which means seam placement becomes a real design question in ADU kitchens that run longer than that. We plan seams around sink cutouts and appliance garages, never through them.
We are an independent contractor, not affiliated with Cosentino or Silestone, and we install the material because it performs well and homeowners can research the warranty themselves.

Signs Your Silestone Home Additions & ADU Planning Is Heading the Wrong Way
- The written price keeps changing. If a contractor gives you a verbal range and then “finds” problems after demolition starts, you’re watching a change-order machine at work. We hand over a written price before any work begins, and that number holds.
- Nobody mentions the 120-inch slab seam reality. A contractor who doesn’t talk about seams before cutting is a contractor who will surprise you with them after. We map seams on graph paper during the estimate walkthrough.
- The permit conversation feels vague. Home additions and ADUs in Long Beach require plans, inspections, and a permit pulled with the city. If the answer is “we’ll handle it later,” the project is not ready to start.
- Surface samples never arrive. You should be choosing between named Silestone colors at the design stage, not after framing. If the samples aren’t on your kitchen table within the first two meetings, the contractor doesn’t actually stock or source the material.
- You’re not asked about kids, pets, or quiet hours. A crew that doesn’t ask about nap schedules and pet zones is a crew that will run loud tools at 1 p.m. and leave a gate open. We ask because it changes how we schedule the work.

AfterReplacement Cost & What’s Included
For a home addition in Long Beach, you’re looking at $45,000 to $130,000. A full ADU construction runs $90,000 to $220,000. A garage conversion falls between $30,000 and $80,000. The Silestone portion of that budget, meaning the countertops, island, and backsplash in the new space, typically lands between $2,000 and $6,500 depending on slab count, edge profile, and seam complexity.
What’s included with us: the written scope of work before anything starts, the permit pulled and inspections passed, shoe covers and drop cloths in the house during the entire project, quiet tools during family rest hours where possible, and a photo of the clean-up before the crew pulls out of the driveway. The 365-Day Done Right Promise covers the completed project. If it’s not done right, we make it right. That includes the Silestone seams, the cabinet alignment, and the backsplash caulk joints.
DIY or Call Us?
You can safely do the measuring and the choosing: figure out your cabinet run length, decide between 2 cm and 3 cm slab, pick colors from Silestone’s current line, and measure for the sink cutout. What you should not do is attempt the slab transport, fabrication, or install yourself. A full Silestone slab weighs around 450 pounds, and a bad lift ends in cracked quartz or a crushed toe. The fabrication requires a wet saw with diamond tooling and a shop space, not a driveway. And the install means dry-fitting, polishing the seam, and getting the overhang support right so nobody leans on an unsupported edge. Call (562) 512-7086 if you want the Silestone work done by people who do this every week. The estimate is free, and the price we write down is the price on the invoice.
FAQs
Silestone quartz carries a 25-year limited warranty for residential use, and in our experience the surfaces in Long Beach ADUs look the same at year 10 as they did at install, provided the seams were cut right and the overhang was supported. The bigger threat here is sun exposure through unshaded windows, which can fade darker colors over a decade. Call (562) 512-7086 and we’ll walk through which colors hold up in high-sun rooms.
Yes, chips and small cracks can be repaired with color-matched resin, and seams can be re-polished if they’ve dulled or lifted. A full replacement is only necessary for structural cracks or a slab that was poorly fabricated in the first place. We’ll tell you which one you’re looking at during the estimate.
Once the template is made and the slab is cut, installation takes one day for a standard kitchen. If the Silestone is going into a home addition or ADU, the surface install happens near the end of the project, after cabinets are set and plumbing is roughed in. We’ll put the surface date in the written schedule before we start framing, so you know when the dust stops.
We don’t warehouse full slabs, but we source directly from local Cosentino distributors in the Long Beach area, which means most colors are available within a week. We also work with KraftMaid for cabinets, Cambria for an alternative quartz option, and Kohler for fixtures, so you’re not locked into one brand if you want to mix materials. Call (562) 512-7086 for exact lead times on the color you’re considering.
