Blanco Home Additions & ADU: The Fort Lauderdale Owner’s Guide
Blanco home additions and ADU construction in Fort Lauderdale typically runs $45,000 to $130,000 for a full addition, with standalone ADUs landing between $90,000 and $220,000 depending on size, utilities, and finish level. Most owners reach out after an existing space stops working: a garage that floods in the afternoon storms, a sunroom that bakes by noon, or an aging addition built before current hurricane codes started leaking at the roofline. We walk the site, map what’s failing against current Fort Lauderdale building requirements, and price the fix or rebuild honestly before you spend a dime.
Which Blanco Models This Applies To
Blanco isn’t a structural framing system, so the model question matters less than the condition of what’s connected to it: roof ties, window flashing, door thresholds, and the sill plate where wood meets concrete. That said, when a Fort Lauderdale home has a Blanco-labeled fixture set (a kitchen sink, faucet, or cabinet pull installed during a prior addition), we match replacements to the existing cutout and mounting pattern so you don’t end up with a new sink that doesn’t fit the old counter. The compatibility gotcha: Blanco kitchen sinks run two drain configurations (3-1/2″ standard and 4″ oversized), and the faucet hole spread can be single-hole, 4″ centerset, or 8″ widespread. If the original installer cut the counter for one spread and you buy a faucet in another, the counter gets redrilled or replaced, which changes the quote. We measure first and match second.
For the addition itself, the decision that matters is OEM structural hardware versus aftermarket hurricane-rated equivalents. Fort Lauderdale code (FBC 8th Edition, which mirrors Miami-Dade HVHZ in most of Broward County) requires impact-rated windows, specific roof-to-wall ties, and flood-zone elevation checks depending on whether you’re east of Federal Highway. We spec parts that pass inspection the first time, not whatever’s cheapest at the supply house.
Styles & brands we work with
Signs Your Blanco Home Addition or ADU Is Failing
- Water staining at the ceiling-wall joint. This usually means the roofline flashing wasn’t lapped correctly or the addition settles differently from the main house, pulling flashing loose. In Fort Lauderdale’s summer rains, the stain spreads fast.
- Doors that stick in August and swing free in January. That’s a humidity cycle problem: the addition’s framing or foundation moves with seasonal moisture. A door that binds only in summer is rarely “just the hinge” – it’s movement underneath.
- Cracks running diagonally from window corners. Diagonal cracks (not hairline verticals) point to shear or settlement in the addition’s wall. Older additions often lack the hold-down hardware current code requires.
- Electrical flicker when the window AC or microwave runs. Undersized sub-panels in older additions were common. If the ADU was wired off a 60-amp sub with no dedicated circuits, the lights dim every time the fridge kicks on.
- AC running nonstop and the room still hot. Additions built without proper attic ventilation or with batt insulation pressed too thin bake under Fort Lauderdale’s sun. The unit isn’t dying – the envelope was never right.
Replacement Cost & What’s Included
For a Blanco-connected addition or ADU in Fort Lauderdale, budget $45,000 to $130,000 for a full home addition and $90,000 to $220,000 for a compliant ADU with its own kitchen and bath. Smaller scopes that fix one failing part range lower: a re-flash and roofline repair starts around $2,500, a window swap for impact-rated units runs $8,000 to $25,000, and a garage conversion to living space runs $30,000 to $80,000. What drives the range: square footage, whether the slab needs lifting or re-pouring, which brands you choose (Cambria and Silestone counters, KraftMaid cabinetry), and whether the city requires flood elevation, architectural review, or both.
Every quote is a written line-item price before any work starts. That price includes labor, materials, permit fees we can identify upfront, and our 365-Day Done Right Promise: if something we built fails inside a year, we come back and make it right at no charge. No change orders unless you ask for a change.

AfterDIY or Call Us?
Some checks are worth doing yourself: take photos of any new cracks with a coin for scale, note when doors stick (seasonally or steadily), and check for water staining after a heavy rain. That gives us a head start when we walk the property.
What you should not DIY: anything touching the roof, structural framing, or electrical. An addition that’s pulling away from the main house can compromise load paths, and a mis-wired sub-panel is a genuine fire risk. High-tension roof ties and hurricane straps under load should only be handled by someone who knows the Fort Lauderdale inspection process. Call (754) 354-7423 and we’ll schedule a time to look. The estimate is free, and you’ll know exactly what we found and what it costs to fix.
FAQs
A properly built addition with impact windows, correct flashing, and proper drainage lasts 50-plus years in Fort Lauderdale’s climate; the weak points are typically the sealants and flashings, which need inspection every 5 years. Call (754) 354-7423 for a written evaluation if yours is showing age.
Most failing additions can be repaired if the framing and foundation are sound; water intrusion and flashing failures are fixable, but chronic settlement with cracking at the slab level usually means partial or full rebuild. We’ll tell you which one you’re looking at after a site visit.
A repair like re-flashing takes 1 – 2 days; a full ADU build in Fort Lauderdale runs 4 to 8 months depending on permitting and scope. You’ll get a written schedule before we start, with photo updates at each milestone.
We keep common Blanco faucet cartridges, drain assemblies, and mounting hardware in our Fort Lauderdale inventory, plus access to the full catalog through our supplier network; if your addition needs a fixture matched, we handle the sourcing. Call (754) 354-7423 and we’ll confirm what’s available before we arrive.
