How 360 Building Rebuilt a Condo Bath After Storm Flooding Safely

I’m Alex Rivera, a renovation project superintendent here at 360 Building. In my 12+ years on job sites across Hollywood, I’ve learned that water is relentless. When a late-summer storm blew through South Florida, I got a call from a homeowner in a Hollywood high-rise. The tone in her voice was one I know well: a mix of panic and frustration. Wind-driven rain had found its way into her master bathroom, leaving a trail of soaked drywall, buckled baseboards, and the unmistakable smell of dampness that signals trouble.

For condo owners, this situation is more than just an inconvenience; it's a race against the clock to prevent mold and structural damage. The client knew she needed more than a quick patch-up job. She needed a team that understood the unique challenges of a condo bathroom remodel in a high-rise setting, especially after a flood. She needed a permanent solution, and that’s why she called 360 Building.

The Assessment

When I arrived at the condo, the visible damage was clear, but my experience told me the real problem was hidden. Water travels, and in a multi-story building, it can seep into wall cavities, subfloors, and adjacent units. The first thing my team and I did was a thorough moisture assessment. Using professional-grade moisture meters and a thermal imaging camera, we mapped the extent of the water intrusion.

What we found was significant. The water hadn't just damaged the drywall behind the toilet; it had wicked up the wall studs and saturated the insulation. The subfloor beneath the tile was also compromised. This building, constructed in the late 1990s, had builder-grade materials that simply weren't designed to withstand the kind of direct, sustained water exposure that a hurricane can deliver. The original waterproofing was minimal, leaving the assembly vulnerable.

It was clear this wasn't a repair job. This required a full gut and rebuild. We explained to the homeowner that to truly solve the problem and prevent future mold growth, we had to take the bathroom down to the studs and concrete slab. This would allow us to properly dry the structure, install a modern waterproofing system, and rebuild it correctly. This project was quickly shaping up to be a textbook Hollywood FL condo bath rebuild case study - one that highlights the importance of doing things right the first time.

We also immediately initiated contact with the building's management. Successfully navigating Broward high-rise remodel logistics is a critical, and often overlooked, part of the job. We coordinated schedules for the service elevator, outlined our debris removal plan, and provided our insurance documentation to ensure a smooth process for both our client and her neighbors.

Our Solution

With a clear plan approved by the homeowner and the condo association, the 360 Building team got to work. Our approach was methodical and focused on long-term performance.

1. Meticulous Demolition and Drying: Our crew carefully sealed off the work area from the rest of the condo to contain dust. We systematically demolished the entire bathroom - tile, vanity, toilet, tub, and all layers of drywall and subfloor - down to the bare concrete and metal studs. All debris was bagged and removed daily according to the building's strict rules. Once the space was open, we deployed commercial-grade dehumidifiers and high-velocity air movers. We didn’t move to the next phase until our moisture meters confirmed the framing and concrete were completely dry. This step is non-negotiable for us at 360 Building.

2. Installing a Fortified Waterproofing System: This was the most critical part of the rebuild. We weren't just replacing what was there; we were upgrading it to a fortress. We installed a complete storm flood bathroom waterproofing system. This involved:

  • Installing new cement board on the walls and a new mortar bed for the shower floor.
  • Applying a full sheet-membrane waterproofing system (like the Schluter-Kerdi system) over the entire shower enclosure, from the floor pan up to the ceiling. Every seam, corner, and screw penetration was sealed with a waterproof banding.
  • We also applied a liquid-based waterproofing membrane to the main bathroom floor before tiling, creating a monolithic barrier against any potential future leaks.

This multi-layered system effectively creates a sealed, waterproof box within the bathroom, ensuring that even if water gets behind the tile, it has nowhere to go but down the drain.

3. Rebuilding with Modern, Durable Materials: With the waterproofing in place, we began the rebuild. We used moisture- and mold-resistant drywall for all the walls. The client chose a beautiful large-format porcelain tile for the shower walls and a complementary non-slip tile for the floor. Our expert tile setters ensured perfect lines and used a high-performance grout with built-in stain resistance. We finished the space with a new floating vanity to create a more open feel, a modern dual-flush toilet, and sleek matte black fixtures. The project was handled by our dedicated 4-person crew and completed within our projected 3-week timeline, a testament to our efficient management of those tricky Broward high-rise remodel logistics.

The Results

The transformation was stunning. Before, the bathroom was a source of stress - a damp, damaged space with an uncertain future. After, it was a bright, modern, and spa-like retreat. The client was thrilled with the aesthetic, but her real satisfaction came from something she couldn't see.

She had peace of mind. She knew that behind the beautiful new tile was a state-of-the-art waterproofing system installed by the meticulous professionals at 360 Building. She no longer had to worry every time a storm was in the forecast. We didn't just fix the damage; we eliminated the underlying vulnerability. We turned a flooding disaster into a significant upgrade in both value and resilience.

"I was so overwhelmed after the storm," she told me on our final walkthrough. "Your team at 360 Building not only handled all the complicated parts with my condo board, but you also built me a bathroom that's more beautiful and secure than it was before. I can finally relax." That's the result we always aim for. This project wasn't just another condo bathroom remodel; it was about restoring a homeowner's sense of security in her own home.
