Blanco Home Additions & ADU: The Jacksonville Owner’s Guide
Bradford Remodeling Co Jacksonville installs Blanco-compatible home additions and ADU structures in Jacksonville, with a typical project range of $45,000 to $130,000 for a home addition and $90,000 to $220,000 for a detached ADU. We’re an independent service provider, not affiliated with Blanco, but we work with Blanco sinks, faucets, and fixtures on every job, so we know how their components hold up under Florida heat and humidity. Most homeowners call us after a Blanco part fails mid-remodel: a faucet cartridge gives out two years after install, a sink rim seal starts weeping at the countertop edge, or a drain assembly corrodes faster than expected because Jacksonville water runs hard. The good news: we stock common Blanco replacement parts on the truck, and we put a written price in front of you before the first tool comes out.
Key Takeaways:
- Home additions in Jacksonville run $45,000-$130,000; ADUs run $90,000-$220,000, with Blanco fixture parts priced separately
- We stock common Blanco faucet cartridges, drain assemblies, and sink mounting clips on the truck
- Bradford Remodeling Co Jacksonville is an independent contractor, not a Blanco dealer or warranty service
- Every project and repair gets a written price before work starts, backed by the 365-Day Done Right Promise
Which Blanco Models This Applies To
Blanco makes three broad product lines that show up in Jacksonville kitchens and ADU wet bars: the Blanco Precision line of kitchen faucets (including the Culina, Linus, and Alta series), the Blanco IKON and Blanco Diamond sink collections, and older Blanco MicroEdge undermount sinks that predate the current lineup. Each uses different mounting hardware, drain flange diameters, and cartridge types. The faucet cartridge is where we see the most confusion: a Culina uses a ceramic disc cartridge with a specific spline count, while an Alta uses a different stem length, and they don’t interchange. If you’re matching a part, the model number is etched on the underside of the faucet base or printed on a label inside the sink basin’s lower rear corner. For sinks, measure the bowl depth and the drain opening before ordering anything, because Blanco has used three different drain opening diameters across the Precision and Diamond lines over the past 15 years.
On the OEM versus aftermarket question: Blanco OEM cartridges and drain kits are worth the extra cost when the part sits behind finished work. An aftermarket cartridge that’s off by half a millimeter will drip, and once the countertop is set, getting to that cartridge means pulling the faucet. We keep genuine Blanco cartridges for Culina and Linus faucets stocked on our trucks in Jacksonville because those two series account for most of what we see. For sink mounting clips and strainer baskets, quality aftermarket parts from brands like KOHLER or Moen work fine, and we’ll quote both options so you decide with real numbers in front of you. The honest answer: Blanco’s proprietary components are well made, but their availability in Jacksonville can be spotty, so having a contractor who stocks the common ones saves you a week of waiting on a part from a distributor.
Styles & brands we work with
Signs Your Blanco Home Addition or ADU Component Is Failing
- A faucet starts dripping from the spout even with the handle fully closed. That’s usually a worn ceramic disc cartridge, and Jacksonville’s hard water accelerates mineral scoring on the disc faces. Once the cartridge is scored, no amount of handle torque stops the drip.
- Water pools at the back of the sink rim or wicks up under the countertop edge. The undermount seal has failed, typically because the adhesive degraded from repeated heat cycles. In Florida, a kitchen that fluctuates between air conditioning and ambient outdoor heat stresses that seal faster than in cooler climates.
- The drain flange sits uneven or the strainer basket won’t seat flush. This means the foam or rubber gasket under the flange has compressed or split. Hard water deposits around the flange make it worse, because they prevent a clean re-seat.
- You hear a grinding or squealing sound when turning the handle. Mineral deposits have worked their way into the cartridge housing, and every turn is scraping the ceramic discs. It’s repairable if caught early; left alone, it scores the discs permanently.
- The sink bowl rocks or gaps at one corner after installation. This is a mounting clip failure or an undersized cutout. Blanco sinks are heavier than most American brands because of their stainless steel gauge, and undersized clips fail under that weight.

AfterReplacement Cost & What’s Included
For Blanco-specific repair work in Jacksonville, we give you a written line-item price before any work starts. Here’s what that looks like in practice:
| Blanco Repair or Installation | Typical Jacksonville Price Range |
|---|---|
| Faucet cartridge replacement (Culina, Linus, Alta) | $180-$420 |
| Undermount sink re-seal (includes adhesive removal and re-bedding) | $350-$800 |
| Drain flange and strainer replacement (Blanco or compatible) | $150-$350 |
| Sink mounting clip replacement (includes countertop gap inspection) | $200-$500 |
| Blanco sink installation in new countertop (part of a kitchen remodel) | $300-$700 (labor), sink separate |
| Home addition with Blanco fixtures integrated | $45,000-$130,000 |
| ADU construction with Blanco kitchen/wet bar components | $90,000-$220,000 |
The range depends on access, condition of the surrounding millwork, and whether the part is Blanco OEM or a quality equivalent. Every repair carries our 365-Day Done Right Promise: if the cartridge drips, the seal weeps, or the drain flange fails within a year, we return and correct it at no charge. That’s in writing, and it’s non-negotiable, because Curtis Lane built this company on the idea that a guarantee you don’t write down isn’t a guarantee.
DIY or Call Us?
There’s an honest split here. If you’re comfortable turning a wrench and you’ve got a basic set of channel locks, you can replace a Blanco strainer basket or tighten a loose drain flange yourself. That’s a maintenance task, not a construction job. What we’d steer you away from is pulling a faucet cartridge without the model number confirmed, because pairing the wrong cartridge means you’ve taken apart your working faucet and now it leaks worse. Also, re-seating an undermount sink is not a DIY job. It requires lifting a 30 to 50 pound stainless steel bowl while applying a continuous adhesive bead in a space where you can’t see the back half of the joint. We’ve re-done too many homeowner attempts where the sink dropped onto the cabinet face and cracked the cabinet frame. If you’re not set up for that, call us at (904) 337-5929 and we’ll send a uniformed technician with the right part and a written price before any work begins.
FAQs
A Blanco ceramic disc cartridge should last 8 to 12 years under normal use, but Jacksonville’s hard water can cut that to 5 to 7 years without a water softener, because mineral scoring on the disc faces is the primary wear mode. Call (904) 337-5929 and we’ll match the right cartridge to your model and give you a firm price before we touch anything.
Yes, in most cases a failed undermount seal can be removed and re-bedded without replacing the sink, as long as the sink bowl itself isn’t cracked and the countertop edge isn’t water-damaged. If the countertop substrate has swelled from repeated moisture, that section needs to be cut out and re-done before a new seal will hold. Call us at (904) 337-5929 for an honest assessment and a written price either way.
A faucet cartridge swap takes 45 to 90 minutes, a drain flange replacement 30 to 45 minutes, and a full undermount re-seal typically 2 to 3 hours including cleanup and cure-time staging. We schedule these as dedicated service calls, not fill-ins, so you get a firm arrival window. Call (904) 337-5929 to schedule.
We stock common Blanco Culina and Linus cartridges, drain flanges, and mounting clips on our service trucks in Jacksonville. For less common parts like Alta cartridges or Diamond series drain kits, we order OEM and typically have them in 3 to 5 business days, and we don’t start the job until the part is in hand. Call (904) 337-5929 and we’ll tell you what’s on the truck today.
