Blanco Home Additions & ADU Nationwide

Blanco Home Additions & ADU: The Woodland Hills Owner’s Guide

A Blanco home addition or ADU project in Woodland Hills typically runs $45,000 to $130,000 installed, depending on square footage, foundation work, and whether you’re adding a ground-floor suite or going up. We handle the full Blanco-compatible scope: permits, plans, foundation, framing, rough-in, and finish. Most Woodland Hills owners call us after discovering their existing Blanco addition or ADU has a structural or systems failure that’s too big to patch: a failing slab, water intrusion at the roofline, or an undersized electrical panel that won’t pass inspection for the new square footage.

Here’s the honest take: Blanco is a solid name in the kitchen and bath space, but “Blanco home addition” really means a remodel or expansion built around Blanco fixtures, sinks, faucets, and sometimes a Blanco outdoor kitchen line that gets integrated into a new ADU. The Blanco part most owners call about is the sink-and-faucet system roughed into a new kitchenette or wet bar. But the job we actually quote is the whole addition: the envelope, the systems, and the finish carpentry that makes the Blanco components work. Sawyer Remodel Woodland Hills is an independent general contractor, not affiliated with Blanco, but we install and work around their product line every week.

Which Blanco Models This Applies To

Blanco’s lineup that shows up in Woodland Hills additions and ADUs breaks into a few clear families. The Blanco Silgranit sinks (the composite granite ones, usually in Metallic Gray or Truffle) are the most common, and they come in undermount, farmhouse, and drop-in configurations. The Blanco Performa faucets with the pull-down spray heads are next. Then the Blanco Supreme and Culina series for higher-end kitchenettes. The compatibility gotcha: Blanco changed the mounting flange and drain-hole spacing on some Silgranit models between 2018 and 2021, so a 2020-era sink won’t always drop into a cabinet cut for a 2016-era unit without a countersink adjustment. Measure twice: the sink cutout and the cabinet base width, not just the bowl depth. We keep the most common Blanco drain kits, mounting clips, and faucet supply lines on our trucks when we work the Warner Center to Topanga Canyon corridor. For anything beyond wear parts, we order the OEM piece directly and schedule the finish work the week it lands.

Signs Your Blanco Home Additions & ADU Is Failing

• Water staining on the cabinet floor or toe kick. Blanco drain baskets and the thin gasket under the sink flange fail first. In Woodland Hills we see this a lot on ADUs with hot-water recirculation lines, because the constant warm-cold cycling degrades the gasket faster. The sink still works, but it’s dripping exactly where you can’t see it until the cabinet base swells.
• Faucet handle travel feels loose or grinds. The ceramic cartridge inside the Performa pull-down has a finite life, usually 8 to 10 years under daily use. When you start feeling a dead zone before the water temperature changes, the cartridge is worn and the handle is chewing into the valve body.
• Low flow at the spray head but normal flow at the spout. Hard water scale from Woodland Hills supply lines builds up in the diverter. The head itself is fine. Replacing the head without cleaning or swapping the diverter doesn’t fix it.
• Cracks or micro-fractures in a Silgranit basin. Blanco’s Silgranit is tough, but a dropped cast-iron pan from the uppers can hairline it. Once water gets into the composite, the crack walks. In a new ADU with a tenant, that’s a call you don’t want to defer.
• The addition itself shows stucco cracks above windows or doors. This isn’t a Blanco faucet issue. It’s a structural one, usually tied to improper shear paneling or foundation movement. We flag it because the ADU envelope has to be right before any finishes go in.

Replacement Cost & What’s Included

When the issue is just Blanco sink or faucet hardware, you’re not looking at the full addition price. Faucet cartridge replacement in Woodland Hills runs about $150 to $350 installed. A full Blanco Silgranit sink swap typically lands between $500 and $1,200 depending on whether the countertop needs re-cutting. A new Blanco Performa or Culina faucet installed runs $300 to $900. And when the Blanco work is part of a larger addition or ADU build-out, the bigger number applies: $45,000 to $130,000 for the full envelope, systems, and finishes. What’s included in any Sawyer Remodel Woodland Hills job is a written price before work starts, live arrival times, and before-and-after photos through The Relay Standard. Luca Romano and the crew don’t show up with a range and then “discover” problems at the invoice. The price you approve is the price you pay.

DIY or Call Us?

If you’re seeing a slow drip at the Blanco drain basket, you can safely check two things: whether the slip nut under the basket is hand-tight, and whether the sink flange sits flush. Beyond that, the plumbing is where DIY goes sideways. Cross-threading a Blanco mounting clip or over-torquing the drain flange on a Silgranit basin cracks it, and that’s a $600 mistake. The bigger danger is on the ADU side: any structural work, shear wall modifications, or electrical panel changes in Woodland Hills require permits and passing inspection. We pull the permits, we pass the inspections, and the work comes with our 365-Day Done Right Promise. If something isn’t right, we make it right.
