Blanco Home Additions & ADU: The Woodland Hills Owner’s Guide
If you own a Blanco sink or faucet in Woodland Hills and the fixture underneath it is failing, an addition or ADU project is likely already part of your plan. Mason Remodeling Co Woodland Hills installs complete Blanco-compatible kitchens, baths, and accessory dwelling units, with full projects in Woodland Hills running $45,000 to $130,000 depending on scope, size, and finishes. The Blanco part most homeowners call us about is the one they didn’t plan for: the sink that’s fine, but the cabinet, counter, or plumbing rough-in around it has failed. That’s the moment to get a written price from someone who knows the Blanco lineup, not just the sink itself. Isaac Pruett has worked with Blanco fixtures across the Valley for years, and we can tell you exactly what it takes to integrate a Blanco into a new build or conversion without redoing the work later.
Which Blanco Models This Applies To
Blanco makes three main fixture categories that show up in Woodland Hills additions and ADUs: the Silgranit composite sinks, the stainless steel sinks, and the pull-down or pull-out faucet lines. The compatibility story matters more than most homeowners expect. Silgranit sinks are granite composite, not coated metal, and they’re heavier than a standard stainless sink. A cabinet or undermount that handled a light steel sink will sag under a 40-pound Silgranit unit. The undermount clips and silicone bed have to be rated for that weight, and a builder who doesn’t know the difference will tell you the sink failed when the cabinet actually did.
The second compatibility factor is the faucet spread. Blanco faucets come in single-hole, three-hole, and pull-down configurations. If the new countertop in your ADU was cut for a three-hole setup and you want a single-hole Blanco, the top needs a deck plate or the holes get capped. The reverse is just as common: a plumber cuts one hole and the homeowner ordered a three-hole Blanco. That’s a countertop repair, not a faucet swap. We always confirm the exact Blanco faucet model and sink dimensions before the countertop is templated, because correcting a hole pattern after the fact in Woodland Hills adds $250 to $500 in stone work. The third thing to know: Blanco’s warranty process requires the original model number from the sink basin sticker or the faucet box. If that sticker is gone, the part is technically out of warranty even if the failure is a factory defect. We tell every client to snap a photo of that label before install.

Signs Your Blanco Home Additions & ADU Is Failing
- Soft spots in the cabinet floor under the sink. This is the number-one failure we see in Woodland Hills additions and ADUs. Leaks from a Blanco faucet base or drain seal sit on particleboard and turn it to mush within a year. The sink itself is fine. The cabinet is gone. That’s a $800 to $3,000 vanity replacement, not a sink repair.
- Granite composite chips around the drain. Silgranit is durable, but it chips if the drain is overtightened or the installer used a metal basket strainer without the proper rubber gasket. Chips near the drain eventually collect food and moisture, and the seal underneath starts to fail. The sink often needs replacement because composite can’t be patched cleanly.
- Faucet drips from the base, not the spout. A drip at the base means the o-ring or cartridge seal inside the body is worn. On Blanco pull-downs, the weight and hose movement grind that seal down over time. It’s an easy fix if caught early, but the water travels down the shank and rots the cabinet before you see a pool.
- The pull-down spray head won’t retract or kinks the hose. Blanco hoses are weighted, and in tight ADU cabinets the weight gets hung up on plumbing, valves, or the back of the cabinet. The hose then kinks at the connection point and the spray pressure drops. Homeowners assume the faucet is bad; the hose routing is usually the problem.
- Undermount sink starts to sag or gap from the countertop. In a Woodland Hills summer, the expansion and contraction of stone and composite moves more than people expect. If the undermount anchors weren’t the right ones for a Silgranit weight load, the sink pulls away from the stone. You’ll see a dark line around the rim where silicone cracked. That gap leaks water into the cabinet every time you run the faucet.

AfterReplacement Cost & What’s Included
For a Blanco sink or faucet integrated into a larger Woodland Hills addition or ADU project, sink and faucet installation itself typically runs $500 to $1,200 in labor, depending on whether the countertop is already cut and the plumbing is accessible. Full kitchen remodels that include a Blanco sink run $14,000 to $45,000. A new ADU with a Blanco kitchen and bath runs $90,000 to $220,000, and a garage conversion with a Blanco bath runs $30,000 to $80,000. The Blanco part is rarely the expensive line. What drives cost is what’s behind and around it: cabinet condition, stone templating, and whether the drain plumbing is leaking into the subfloor. Every price we give in Woodland Hills is a written, line-item price before any saw touches wood. That means the Blanco model, the faucet finish, the cabinet, the plumbing rough-in, and the finish work are all listed with dollar figures on paper before you sign anything. We don’t open up a wall and email you a change order. The 365-Day Done Right Promise applies to every Blanco install we complete: if the sink, faucet, cabinet, or surrounding work fails within a year of completion, we return and fix it at no charge.
DIY or Call Us?
A homeowner can safely check a few things. Run your hand along the Blanco faucet base with the water on and see if moisture collects. Look under the cabinet with a flashlight and press on the floor around the drain trap. If it flexes, it’s wet. You can also pull the spray head down and check the hose for kinks where it rubs against the cabinet back. That’s where DIY should stop. Undermount sinks under tension from twisted anchors, silicone failures under a granite composite basin, and cabinet repair under a live plumbing stack are three situations where a wrong move makes the problem double in cost. If you’re in Woodland Hills and the Blanco is fine but the structure around it isn’t, call us at (831) 290-6866. We’ll tell you what’s failing, what it costs to fix, and whether the rest of the project is worth doing now or can wait. No pressure, no vague estimates.
FAQs
A Blanco Silgranit sink typically lasts 15 to 25 years with normal use, and the longevity holds up in Woodland Hills because composite doesn’t rust or pit the way stainless can. The failure point is the cabinet and countertop around it, not the sink itself.
Call (831) 290-6866 if you need a concrete answer for your specific setup. The estimate is free.
Most Blanco faucets can be repaired with a new cartridge, o-ring, or hose, and those parts cost $25 to $80 before labor. Replacement makes sense when the body is corroded from a long-term base leak or the pull-down hose fitting is stripped. We’ll tell you which one applies to yours.
Call (831) 290-6866 and we’ll walk through what you’re seeing before we schedule anything.
A straightforward Blanco faucet swap takes one to two hours once the old unit is out. An undermount sink replacement takes half a day because the countertop edge has to be cleaned, the silicone bed has to cure, and the plumbing has to be reconnected and tested. If the cabinet floor is rotted, add a day for cabinet replacement.
Call (831) 290-6866 for a timeline on your specific job. Written price comes first, no digging starts without it.
Yes, we stock common Blanco cartridges, o-rings, hose weights, drain assemblies, and mounting clips, and we can order any model-specific Blanco part within days. We also work with KraftMaid, Cambria, and Silestone for the surrounding materials in Woodland Hills projects, so the cabinet and counter material does not sit in limbo waiting on a third party.
Call (831) 290-6866 and give us the model number off the Blanco sticker under the basin. We’ll tell you exactly what’s in stock and what ships.
