Blanco Home Additions & ADU: The West Palm Beach Owner’s Guide
Building a Blanco home addition or ADU in West Palm Beach typically runs $45,000 – $130,000 for a room addition, and $90,000 – $220,000 for a full ADU with kitchen and bath. Bradford Remodeling Co West Palm Beach plans the addition, secures permits, and builds to spec so the new square footage ties cleanly into the existing structure. Most owners call us after realizing their Blanco kitchen or bath layout can’t accommodate the way they actually live now: too little counter space, no room for a second sink, or a garage that’s become a storage catch-all instead of rental income.
Blanco is known for engineered sinks, faucets, and kitchen systems, not structural framing. So when we talk about a “Blanco home addition,” we mean an addition built around the Blanco fixtures you’ve already got or plan to install, with the plumbing rough-in, cabinet layout, and countertop overhang planned around those exact dimensions. That’s the part most contractors get sloppy about. Blanco sinks have specific mounting requirements. Get the rough-in wrong and you’re cutting into finished millwork to fix it.
We are an independent West Palm Beach remodeling contractor, not a Blanco dealer or affiliate. We install their products because they hold up and because parts are available when something does fail. The guide below covers what we’ve learned on the job, the way Curtis Lane, our owner, would walk you through it standing in your kitchen.
Which Blanco Models This Applies To
For the purposes of planning an addition or ADU around Blanco fixtures, the relevant question is which sink and faucet series you own, because those numbers drive the cabinet widths, countertop cutouts, and rough-in heights. The main lines we work with in West Palm Beach are the Blanco Silgranit composite sinks (the Precis, Diamond, and Performa series), the Blanco Culina and Ikon faucets, and the Blanco Precision and Grazia bar sinks. Each has a published spec sheet with minimum cabinet base requirements, and those numbers are not interchangeable.
Here’s the compatibility gotcha most owners hit: a Blanco undermount composite sink needs a cabinet base 1.5 to 3 inches wider than the sink bowl, and the rim requires a flat countertop surface with no lippage. If you’re adding a wing off the kitchen and the cabinet fabricator lays an engineered quartz top with a seam running through the sink run, that seam must be shimmed dead flat or the Silgranit rim will sit proud and catch water. We flag this at the measuring stage because fixing it after install means pulling stone. Same thing goes for Blanco’s bottom grid kits; they’re model-specific, and a grid from a Precis unit won’t sit right in a Diamond bowl.
OEM Blanco parts (replacement grids, mounting clips, strainer baskets) are worth the money on a kitchen you use daily. The aftermarket universal clips and baskets we see at big-box stores are stamped thinner and rust faster in Florida’s coastal air. For a rental ADU, an aftermarket basket from a quality brand can be fine. Your call; we’ll tell you the price difference and let you decide.
If you can’t find the model number, check the underside of the sink bowl for a molded label or stamp. If the sink is already installed, take a photo from below with a flashlight. We’ll match it. Bradford Remodeling Co West Palm Beach also works with and installs KraftMaid, Cambria, and Silestone cabinetry and surfaces, which frequently pair with Blanco fixtures in our addition and ADU jobs.

Signs Your Blanco Home Additions & ADU Is Failing
Most “failed” addition or ADU projects aren’t structural failures. They’re integration failures; the room works on paper and fights you in real life.
- Water pooling around the sink rim. This is the classic sign the countertop fabrication didn’t account for Blanco’s rim tolerance. The sink rim sits above the counter grade and every morning’s splashes end up on the floor. The fix usually means removing and re-setting the sink, sometimes re-shimming the stone.
- The faucet base wobbles every time you swing the spout. Blanco faucets mount through a single hole or a pre-rinse deck plate. If the countertop crew over-drilled the hole, the base plate never fully seats. A wobble means the lock nut underneath is backing off or the hole needs a reinforcement plate.
- The new room never stays cool or dry. In West Palm Beach, an addition with undersized insulation, a mismatched HVAC trunk line, or a slab that wasn’t graded for sheet flow fails quietly. You see it in rising energy bills and a musty smell in the corner. This is a build defect, not a fixture problem.
- Doors and windows stick within a year. Florida clay shrinks and swells seasonally. If the addition’s slab wasn’t poured with proper compacted fill or the openings weren’t sized for hurricane-strap deflection, you’ll feel it in the door casings and window jambs by the second summer.
- Cabinet doors open into the Blanco faucet arc. This is a coordination failure between the cabinet order, the sink placement, and the faucet model. A Culina high-arc faucet needs clearance; an Ikon semi-pro coil needs even more. If the addition’s cabinet layout didn’t carry Blanco’s published clearances onto the shop drawings, you’ll be flipping a door past a spout every day.

AfterReplacement Cost & What’s Included
Home additions in West Palm Beach run $45,000 to $130,000 dependent on foundation type, roofline transition, and whether the room is conditioned space or a shell. A full ADU with kitchenette and bath starts near $90,000 and can hit $220,000 when you add impact glazing, a slab-on-grade foundation with proper moisture barrier, and hurricane-rated strapping throughout. Kitchen remodels inside those additions run $14,000 to $45,000 with Blanco fixtures and the cabinetry that supports them.
Every Bradfurd Remodeling Co job receives a written price before any work starts. The quote itemizes the addition’s scope: foundation, framing, rough plumbing and electrical, insulation, drywall, trim, fixtures, finishes. What we quote is what you pay. No numbers that move at the door, no “unforeseen conditions” upcharges unless you change scope, and if something changes we call before we touch it. The work is covered by our 365-Day Done Right Promise: if the build fails within a year of completion, we come back and correct it at no charge. That covers the framing, the finish work, the Blanco fixture installation, everything we touched.
Straight number, full scope, no surprises after the invoice.
DIY or Call Us?
If your Blanco sink has a clogged strainer or a loose faucet handle, you can handle that with a basin wrench and a drain key. If the issue is a cracked Silgranit bowl, a granite countertop that shifted, or an addition’s slab showing cracks at the corners, call a contractor. A cracked composite sink under a stone countertop is not a safe thing to yank on; if that bowl splits further while you’re under it, you’re looking at a face full of composite and a dropped stone rim.
The DIY line is where the work is structural, waterproofed, or load-bearing. That’s where we insist. A West Palm Beach addition has to meet wind-load and flood-plain requirements, and if it’s not strapped right, the first named storm proves it. If you’d like us to assess what you’ve got, call (728) 203-9809. We’ll give you a straight read.
FAQs
Most additions take 8 to 16 weeks from permit to final walk-through, with ADUs running 4 to 6 months because of the kitchen and bath rough-ins. Permitting through the City of West Palm Beach is running 3 to 6 weeks on average for residential additions, and Bradford Remodeling Co West Palm Beach pulls those permits as part of the written price. Call (728) 203-9809 for a timeline tied to your scope.
That depends on the damage. A Blanco Silgranit surface scratch can be lightly refinished, and faucet cartridges and O-rings are replaceable parts from Blanco. A cracked bowl or a separated rim cannot be safely repaired, so replacement is the only correct call. We’ll tell you which case you’re in before any money changes hands.
We routinely carry the most common replacement items for Blanco Silgranit sinks and standard Blanco faucet lines: mounting clips, strainer assemblies, bottom grids for common series, and faucet cartridges. If it’s an unusual model or a discontinued series, we’ll order the OEM part and schedule the install when it arrives. We install KraftMaid, Cambria, and Silestone products alongside Blanco fixtures, so the kitchen ties together as a system.
The Garrison Standard is the written operating framework behind every Bradfurd Remodeling job: background-checked, uniformed technicians; written pricing before work starts; and the 365-Day Done Right Promise on completed work. Bradford Remodeling Co West Palm Beach has been part of the Garrison Partners family since 2004 and operates as an independently owned and operated business held to that standard.
