Blanco Home Additions & ADU: The Orlando Owner's Guide
A Blanco home addition or ADU in Orlando typically runs $45,000 to $130,000 installed, depending on square footage, foundation work, and whether you're building up or out. Most Orlando homeowners call us when they realize their Blanco product line was never designed to be a structural starting point, and the parts they bought from a big-box store don't match the load requirements for Florida's wind codes and humidity. We stock and install Blanco-compatible hardware, fasteners, and trim kits, and we'll match the right part to your specific Blanco series and Orlando building code the first time.
Here's what usually happens: an owner starts with a Blanco sink, faucet, or cabinet system, decides to build an addition or ADU around it, and discovers mid-project that the Blanco mounting hardware or drain assembly doesn't meet Miami-Dade or Florida Building Code requirements for a permitted structure. That's the moment they call us.
Key Takeaways:
- Blanco home additions and ADUs in Orlando: $45,000 to $130,000 installed
- We match Blanco parts to your exact model and Florida code requirements
- Written price before work starts, no change orders at the door

Which Blanco Models This Applies To
Blanco makes several product lines that Orlando homeowners build around, and the compatibility question matters more than people think. If you're adding a kitchen or ADU and keeping your existing Blanco sink or faucet, you need to know which series you have before anyone cuts a wall or pours a slab.
Blanco sinks fall into three main groups that affect rough-in dimensions: the undermount stainless lines (like the Blanco Performa and Diamond series), the Silgranit composite sinks (which need specific mounting clips and a wider cutout tolerance than stainless), and the farmhouse/apron-front models (which require cabinet face modifications and support brackets rated for the extra weight). A Silgranit sink weighs close to 40 pounds dry, and when it's full of water and dishes, the cabinet below it is carrying real load. In Orlando homes built before 2002, we regularly see particleboard sink bases that were never meant to hold that weight long-term, especially with the humidity swings we get from April through October.
For ADUs specifically, the Blanco faucet lines (like the Culina and Linus series) use ceramic disc cartridges that are excellent for hard water, which matters in Orlando where municipal water runs 120 to 180 ppm hardness depending on your neighborhood. But the supply line connections are metric on some European-spec Blanco faucets, and we see owners buy the wrong adapter and end up with a slow leak behind a new ADU wall. That's a $45 part that becomes a $4,000 drywall and mold repair if you don't catch it. The OEM-vs-aftermarket decision for Blanco is straightforward: for cartridges and mounting clips, OEM is worth it because the tolerances are exact. For supply lines and P-traps, quality aftermarket works fine if it's code-rated for Florida.

Signs Your Blanco Home Additions & ADU Is Failing
- Sink rim lifting or pulling away from the countertop. The undermount clips have loosened or the adhesive failed, usually from thermal cycling in an unconditioned Orlando garage ADU. You'll see a visible gap and water working its way under the lip.
- Dark staining or soft spots on the cabinet floor under the sink. The Blanco drain gasket has dried out and is seeping slowly. By the time you see the stain, the cabinet base is usually already swelling.
- Faucet drips after the handle is fully off. Ceramic disc cartridges don't usually drip, so if yours does, you either have debris scored into the disc or a worn seat. In Orlando's hard water, mineral buildup is the usual culprit.
- The farmhouse sink has a visible crack or hairline at the front apron corner. This is a support failure, not a material defect. The cabinet wasn't reinforced and the sink has been flexing under load. Silgranit will crack if the base isn't dead flat and fully supported.
- Water pooling at the base of the faucet but not from the handles. The O-ring at the faucet body has failed, or the deck plate gasket was installed on a rough surface. We see this in Orlando ADUs where tile or stone was installed after the faucet, leaving an uneven seat.

AfterReplacement Cost & What's Included
For a Blanco-specific repair or part replacement within an existing structure, Orlando pricing lands in these ranges:
- Blanco sink remount/reclip with new mounting hardware: $350 to $900
- Blanco faucet cartridge replacement: $180 to $450
- Farmhouse sink cabinet reinforcement and reinstall: $700 to $1,800
- Full Blanco sink and faucet replacement with plumbing: $1,200 to $3,800
- Blanco-compatible ADU kitchen rough-in (plumbing, drain, cabinet prep): $3,500 to $8,000 as part of the larger ADU build
Every quote includes the part itself, the labor, the disposal of the old part, and a written price before we pick up a tool. If the Blanco part we install fails within the first year, the 365-Day Done Right Promise covers the correction. For full additions and ADU construction, the $45,000 to $130,000 range depends on whether you're converting existing space or building new square footage, and we'll walk you through that line by line before you sign.
DIY or Call Us?
You can safely check a few things yourself: confirm the Blanco model number (it's stamped on the underside of the sink bowl or on the faucet body under the handle), look for visible gaps or staining, and shut off the water supply under the sink if the faucet is actively leaking. That's information we can use on the phone to give you a tighter estimate.
What you shouldn't do is attempt to unclip or remount an undermount Blanco sink yourself. The sink is heavy, the clips are under tension, and if a Silgranit sink drops, it's a broken sink and possibly a broken toe or worse. We've also seen homeowners try to silicone a farmhouse sink back into place without addressing the structural support underneath, and the crack comes back within a year. If you're in Orlando and the Blanco part is failing, call (850) 809-0306 and we'll come look at it. The estimate is free.
FAQs
A Blanco Silgranit sink should last 20 to 30 years if the cabinet below it is properly supported and the mounting clips stay tight, but Orlando's humidity and hard water put more stress on faucets, where you can expect 8 to 15 years from a cartridge before it needs attention. Call (850) 809-0306 and we'll tell you whether yours is worth repairing or replacing based on what we find.
Hairline cracks can sometimes be filled with an epoxy color-matched to Silgranit, but the repair is cosmetic, not structural, and the crack will usually reappear if the underlying support issue isn't fixed. We'll tell you honestly whether a repair makes sense or whether you're better off replacing the sink now before it fails during a holiday dinner.
A faucet cartridge swap takes under an hour, a sink remount takes half a day, and a full farmhouse sink cabinet reinforcement and reinstall can take a full day if we're rebuilding the support structure. We'll give you a live arrival time and a photo update when the work is done, so you're not sitting around wondering.
We keep the most common Blanco cartridges, drain assemblies, mounting clips, and supply line adapters on the truck for Orlando jobs, and if your part is a less common series, we can have it within a day or two through our supplier network. Call (850) 809-0306 with your model number and we'll tell you what we have and what the exact quote looks like.
