Emergency leak response
Balcony leaks are stressful, especially when they reach a neighbor’s ceiling. Here is what homeowners and associations say about how A-1 handled the repair, the schedule and the finish.
Balconies take a beating in South Florida. Sun, salt air and daily rain soak into concrete and grout, then find the path of least resistance: the unit or room below. Balcony waterproofing puts a continuous membrane between the walking surface and the structure so that water drains off instead of in.
Most balcony leaks start in the same few places. The joint where the slab meets the wall, the door threshold, the railing posts, the drain, and the edge where the slab turns down. We inspect all of them, not just the stain on the ceiling below.
Depending on the finish you want, we install a membrane under new tile or a decorative balcony coating directly on the concrete. Either way, cracks and damaged concrete are repaired first through our concrete restoration process.
On a waterfront mansion in Boca Raton, we replaced every balcony on the home. The old finishes were removed down to the structure, damaged concrete was repaired, and a new waterproofing membrane went in before the new tile was set.
Projects like this are where details matter most: proper slope toward drains, sealed railing penetrations, and flashing at the walls and door openings. Done right, the tile looks great and the rooms below stay dry.
Whether it is one condo balcony or every terrace on a large home, the process is the same: find the cause, fix the substrate, then waterproof.
The right system depends on the finish you want and how the balcony is built.
For tiled balconies and terraces, a waterproofing membrane goes down before the tile, with flashing at walls and thresholds.
Liquid-applied traffic coatings bond to the concrete and form a seamless, textured, slip-resistant walking surface in your choice of color.
For decks over living space, we build a full system with reinforcement at corners, drains and every penetration.
Spalled edges and exposed rebar are cleaned, treated and rebuilt before any waterproofing goes on top.
We coordinate with residents and property managers so balconies are out of service for as little time as possible.
We test for hollow tile, check the drains and slab edge, and photograph every defect we find.
Failed tile or coatings come off, and cracked or spalled concrete is repaired down to sound material.
We install the membrane or coating system with extra reinforcement at walls, thresholds and railing posts.
New tile or the finish coat goes on, and we confirm the balcony drains the way it should.
Usually because water gets past the tile or surface and into the concrete, then travels to a crack, joint or edge. Failed membranes, cracked grout, bad threshold sealant and railing penetrations are the most common causes.
Sometimes a clear sealer or grout repair helps for a short time, but a long-term fix almost always means removing the tile, repairing the slab and installing a real membrane underneath.
Yes. We work with condo associations and property managers on single balconies and full-building programs, including balcony items found in milestone inspections.
Our waterproofing work carries a written workmanship warranty of 5 to 15 years depending on the system and the scope of the job.
A single balcony coating is often done in a few days, including cure time. Tile replacement and concrete repair take longer. We give you a schedule with the estimate.
We will find where the water is getting in and give you a written price for the repair. See all of our waterproofing services or claim 25% off a leak repair. Licensed CCC1333587 | CBC1263521.
