CWS Construction in Sunnyvale, CA | Iron Beam Contractors
We’re Iron Beam Contractors, and we handle CWS cabinet, countertop, and shower enclosure work across Sunnyvale from full teardown rebuilds to ADU bathroom fits. The thing that separates our CWS work here from anyone else’s is prep: before we hang a CWS Concord cabinet or set a quartz top, we correct the slab, the wall, and the substrate. If you’re in one of Sunnyvale’s 1950s ranch homes with floors that have drifted out of level over 70 years, call (833) 756-5936 and we’ll come measure what’s actually there before quoting a number.
Why Sunnyvale Residents Choose Us for CWS Service
We’ve installed CWS Concord shaker kitchens, Ellenton bathroom vanities, and frameless glass enclosures in enough Sunnyvale ranches to know this line’s quirks cold. Nolan Driscoll spent two decades framing, pouring, and reinforcing before founding Iron Beam, and he runs crews that track CWS spec changes instead of treating the product like every other cabinet box. What that means for you: we know when a CWS door should be replaced versus refinished, when a hinge is the problem versus the wall behind it, and when a “simple shim” is about to become a cracked countertop seam six months later.
We’re an independent CWS service provider. We are not manufacturer-affiliated or authorized, and we don’t pretend to be. What we are is a full-scope general contractor that sources genuine CWS parts when the box is sound and specifies aftermarket fronts and seals that meet or exceed CWS specs when a profile’s been discontinued. One contractor, every phase, from blueprint to backyard.

Common CWS Construction Problems We Solve in Sunnyvale
- Cabinet box swelling at the toe kick. Sunnyvale’s flat, clay-heavy former orchard soil holds water against slab-on-grade foundations. In 94085 and 94086 ranch rebuilds, winter rain wicks moisture up through the slab, and untreated toe kicks on CWS cabinets absorb it. We seal and isolate the base before install, not after the finish starts peeling.
- Quartz edge chipping at sink cutouts. 1950s and 1960s Sunnyvale framing is rarely level. When CWS quartz gets shimmed over a slab that’s off by half an inch, the stone carries stress it was never designed for. Chips at the sink cutout are almost always a substrate problem. We float level curbs first.
- Vanity finish discoloration behind vessel sinks. Pre-1970 Sunnyvale tract homes often have uninsulated exterior bathroom walls. Condensation builds behind a CWS Ellenton vanity, and the finish clouds. We add blocking and a moisture barrier before the vanity goes in.
- Frameless shower hinge sag on out-of-plumb walls. A CWS frameless door mounted to a 1960s tile wall that’s drifted 3/8 inch off vertical will sag at the hinge and the seal will fail. The door isn’t the issue; the wall is. We correct the wall or build out the blocking before we hang the glass.
- Buried orchard roots and old irrigation in the dig path. On Sunnyvale’s flat lots, we routinely cut through old orchard roots and buried irrigation when setting base cabinets or vanity plumbing. You plan for it, you price for it, and you don’t act surprised when it shows up.
CWS Service in Sunnyvale: What Local Conditions Mean for Your Equipment
Here’s the thing that doesn’t apply in Palo Alto, Los Altos, or anywhere in the hills. Sunnyvale sits on flat former orchard land. That sounds like a real estate footnote until you’re on your hands and knees under a CWS kitchen island looking at a 60-year-old irrigation line nobody capped. Our crews have dug enough footings and set enough base cabinets in the 94086 and 94087 ZIPs to know that orchard-era roots and buried fill are a regular part of the dig. When we install CWS cabinets or set a vanity in a Sunnyvale ADU, we budget time for cutting through those roots and abandoning old water lines before we level the base. Contractors who only work the hill cities never see this, and they don’t know to look for it. That extra hour of ground work is the difference between a CWS install that’s dead level and one that telegraphs every mistake through the countertop.
If the structure makes sense on paper, it’ll hold in the field. If it doesn’t make sense on paper, we fix it before we touch a beam.
CWS Models & Products We Service in Sunnyvale
We work on the CWS product lines most common in Sunnyvale remodels and rebuilds. That includes CWS Concord shaker-style cabinets, the Ellenton bathroom vanity collection, CWS quartz countertops in Calacatta and Carrara looks, and CWS frameless glass shower enclosures with 3/8-inch tempered glass. We stock common CWS door profiles, drawer hardware, and glass hinge parts locally for faster turnaround, and we source genuine CWS replacement doors, drawers, and glass hardware when the cabinet box and stone are structurally sound. For finish damage or discontinued profiles, we specify aftermarket fronts and seals that meet or exceed CWS specs, and we’ll tell you plainly when a 30-year-old CWS vanity is worth refinishing versus replacing, especially in ADU and rental conversions where budget per unit actually matters.

AfterCWS Service Pricing in Sunnyvale
What you’ll pay for CWS work in Sunnyvale depends on the condition of the floor, the wall, and the site. If the slab is level and the framing is square, the job is straightforward.

FAQs – CWS Construction in Sunnyvale
Yes, and we do it regularly. We don’t shim the cabinets over a slab that’s off by three-quarters of an inch; we float a level curb or build up the substrate so the box sits flat and the countertop seams land true. That’s the step the other two bidders skipped on a Washington Park kitchen we corrected last year, and it’s why the seams stayed dead flat. Call (833) 756-5936 if your floor has visible slope.
We locate and abandon the old lines, cut the roots, and prep the footing before we set the vanity. Sunnyvale ADUs go in on lots that were orchards sixty years ago, and old irrigation is part of the ground. We plan for it in the quote so it’s not a change order you find out about mid-project.
If you hire us and we install on uncorrected framing, that’s on us. If someone else shimmed the stone over an out-of-square box, the substrate is the root cause and the chip will come back. We correct the cabinet or the curb before the stone goes down, and we write the prep into the scope. Call (833) 756-5936 for an assessment.
We do when the enclosure is structurally sound and the part is available. Genuine CWS hinges and seals maintain the factory geometry and seal. When a profile is discontinued, we source aftermarket hardware that matches or exceeds the CWS spec, and we tell you before we buy it. We don’t quietly swap in generic parts.
Yes, with the right sequencing. Sunnyvale’s rainy season runs winter, and moisture wicking through flat slabs is a real concern on 94085 and 94086 ranch lots. We stage material, seal open concrete, and schedule exterior penetration work around dry windows when the project involves outside walls. Interior CWS installs continue through the wet months. Call (833) 756-5936 to talk about your timing.
