Blanco Home Additions & ADU: The Orlando Owner’s Guide
Blanco home additions and ADU construction in Orlando typically runs between $45,000 and $130,000 installed, depending on square footage, foundation type, and whether you’re adding a single room or a full accessory dwelling unit with a kitchenette and bath. We install Blanco-compatible fixtures and cabinetry hardware across home additions, and our crews regularly work on projects from College Park bungalows to newer Winter Park builds. Most Orlando homeowners find us after their addition was quoted by another contractor at a number that somehow crept up $20,000 once the slab was poured.
Here’s the short version of what to know: a home addition in Orlando is priced by square footage and the systems involved (electrical, HVAC, plumbing), not by the brand of sink or cabinet pulls you choose later. Blanco fixtures are a finish-level decision. The structural work underneath them is where your budget actually goes. That said, Blanco undermount sinks, pull-down faucets, and cabinet hardware have specific installation requirements that affect rough-in dimensions during framing, and we account for those before the drywall goes up.
Which Blanco Models This Applies To
Blanco makes kitchen and bath fixtures, not framed walls or roof trusses. The brand shows up in home additions and ADUs two ways: the Blanco sink and faucet packages specified in kitchenettes or wet bars, and Blanco cabinet hardware and accessory kits used in pantry and bath cabinetry. If you’re matching an existing Blanco product to new millwork, the compatibility question is about sink dimensions and mounting style, not model generation.
Blanco sinks come in four mount types: undermount, drop-in (top-mount), farmhouse (apron-front), and flush-mount. Undermount is the most common in Orlando additions because it works with solid-surface counters like Cambria and Silestone. The rough opening (the hole cut in the countertop) is model-specific. A Blanco Precis or Diamond series undermount sink has a different radius and depth than a Blanco Quatrus, and if the fabricator cuts the counter for one and you ordered the other, the countertop goes back to the shop. That’s a $400 to $900 mistake we see often enough to check the spec sheet before the template appointment.
OEM Blanco parts, like sink clips, strainer baskets, and faucet cartridges, are worth the extra cost in an addition or ADU. Aftermarket drain assemblies fit the drain hole but often use thinner flange material that flexes and leaks at the gasket within two years. For a permanent structure, OEM Blanco components mean the fixture outlasts the countertop’s first owner.
Styles & brands we work with
Signs Your Blanco Home Additions & ADU Is Failing
- Sink flange lifting from the counter. The silicone bond between the Blanco undermount sink flange and the stone or quartz countertop has failed. In Orlando’s humidity swing, this happens faster if the original installer used basic silicone instead of a quartz-rated adhesive. Water seeps into the cabinet below.
- Water staining the cabinet floor under the Blanco fixture. Almost always a failed drain gasket or a supply line that was overtightened at the fitting. Blanco’s European threading is close to NPT but not identical, and a hand-tightened fitting that felt fine at install loosens after a few hundred thermal cycles from Orlando’s hard water heater temps.
- Faucet base wobble or visible gap at the deck plate. The Blanco faucet’s mounting nut backed off, or the installer skipped the rubber deck gasket during rough-in. Once movement starts, the O-rings inside the cartridge wear unevenly and drip at the base.
- Low water pressure at the new Blanco pull-down faucet. Mineral buildup from Lake Apopka-sourced water lines clogs the aerator screen or the internal cartridge seats, especially in older Orlando neighborhoods with aging supply pipes upstream of the fixture.
- Cabinet hardware loosening or pulling from face frames. The cabinet boxes in the addition settled, or the installer used short screws into MDF. Blanco hardware needs a solid wood or plywood anchor. Face frames that were built with particleboard at 1950s-era tolerances (common in College Park additions) strip out quickly.

AfterReplacement Cost & What’s Included
For a full Blanco home addition in Orlando, budget $45,000 to $130,000 installed. An ADU with a kitchenette and bathroom runs $90,000 to $220,000. The Blanco-specific portion, meaning the sink, faucet, and cabinet hardware package for an addition with a wet bar or secondary kitchen, adds roughly $900 to $3,400 to the project total depending on series and finish. That’s parts and labor. Here’s the line-item breakdown for the fixture scope alone:
- Blanco undermount sink (Precis, Diamond, or Quatrus series): $350 – $900 depending on size and gauge
- Blanco pull-down or bar faucet: $250 – $750 depending on finish (stainless, chrome, matte black) and spray function
- Blanco cabinet hardware kit (pulls, knobs, hinges for 8 – 12 openings): $120 – $400
- Installation labor for sink, faucet, and hardware: $550 – $1,350 including rough-in adjustment, countertop cut verification, and drain assembly
What drives the range on the addition itself is foundation work. Orlando sits on a mix of sandy soil and karst limestone, and a 200-square-foot bump-out with continuous footers costs less than an ADU on a separate slab with its own electrical service and HVAC split. We give you a written price before any work starts. The number on day one is the number on the invoice, and the 365-Day Done Right Promise covers the Blanco fixtures and all the work behind them in writing.
DIY or Call Us?
You can check the cabinet floor for water stains, wiggle the faucet base, and run your finger along the sink flange to feel for separation. That tells you if a problem exists. It does not tell you whether the countertop needs to be reset, the drain line re-gasketed, or the cabinet face frame rebuilt. These are things we diagnose in person, and Trevor Nash has spent enough years looking at 1950s-era Orlando framing to know exactly where DIY fixes on older additions go wrong: usually the joint between original structure and new steel, which moves differently in Florida’s wet-dry cycles.
If the Blanco fixture is dripping or loose and you’re reasonably handy, you can tighten the mounting nut under the sink or clean the aerator. Past that, call us at (850) 427-6454. The estimate is free, and you’ll get a written number before anyone picks up a tool.
FAQs
Blanco stainless sinks in 18-gauge or thicker typically last 25 to 30 years in Orlando’s climate, though the silicone bond to the countertop usually needs redoing at the 10 to 12 year mark because of humidity and thermal cycling. Faucet cartridges last 5 to 8 years depending on water hardness. Call (850) 427-6454 and we’ll tell you if yours is a repair or replacement.
Yes, in most cases. We drop the sink slightly, clean the old adhesive from both the flange and the stone, re-apply a quartz-rated bonding agent, and re-clamp with the Blanco mounting clips. The counter stays in place. If the countertop was cut wrong for the model you have, that’s a different conversation. Free estimate covers finding out which one you’re dealing with.
The Blanco sink, faucet, and hardware package in a home addition or ADU installs in one day, sometimes half a day if the rough-in was sized correctly and the countertop template matched the sink’s spec sheet. That one day assumes the addition itself is already framed, drywalled, and painted, which is a separate project timeline we’ll lay out for you in writing. Call (850) 427-6454 for the full schedule.
We keep the most common Blanco Precis and Diamond undermount sinks, pull-down faucets in stainless and matte black, and hardware kits on hand for Orlando addition and ADU projects. Special-order finishes like Blanco’s PVD brushed gold come directly from the manufacturer and add about two weeks. We’ll confirm availability when we quote you, not after demo day.
If you’re planning a home addition or ADU in Orlando and the Blanco details matter to you, call (850) 427-6454 for a free estimate. We’ll give you a written price and a written guarantee before the first wall goes up. That’s how we work, and that’s how it should’ve worked the first time.
