Leak Detection
Commercial Leak Detection & Repair in Miami
Zaldak Maintenance locates and repairs hidden water leaks in commercial buildings across Miami-Dade and South Broward, including slab leaks, in-wall and ceiling leaks, riser and supply-line failures and condo leaks that travel between units, using non-invasive detection before any wall or floor is opened.
Hidden leaks are expensive because they stay hidden
A stain on a ceiling, a water bill that jumped, a warm spot in a slab floor, a musty corridor: these are often the first signs of a leak that has been running for weeks. In concrete construction, water travels along slabs and pipe chases and shows up far from where it starts, which is why condo associations and managers end up arguing about which unit is responsible.
Finding the source quickly limits the damage, the mould risk and the insurance dispute. Our approach is to test and trace first, open walls only where the evidence points, and document what we found so the association, the owners and the insurers are working from the same facts.
Leaks we find and fix
- Slab leaks in supply and drain lines under concrete floors
- In-wall and ceiling leaks from supply lines, fittings and drains
- Riser and stack leaks in multi-storey buildings
- Condo leaks traveling between units or from balconies and windows
- Water heater, fixture and valve leaks behind finishes
- Irrigation and exterior line leaks driving up water bills
How we locate a leak
We start with the building's layout and the symptoms, then isolate zones with pressure testing to confirm which line is losing water. Moisture meters, thermal imaging and acoustic listening help pinpoint the spot, and camera inspection covers drain lines. Only then do we open the smallest possible area to make the repair.
After the repair we confirm the line holds pressure and document the source, the fix and the affected areas with photos. For condo associations that record is often what settles the question of responsibility between the association and owners.
Who calls us for leak detection
Condo boards and HOAs dealing with water moving between units, property managers with an unexplained spike on a water bill, office buildings with ceiling stains above tenant space, and restaurants with wet floors that won't dry. We work across Miami-Dade and South Broward, including the high-rise corridor in Miami Beach and the buildings of Fort Lauderdale and Hollywood.

FAQ
Questions we get asked
How do you find a hidden water leak?
Hidden leaks are found by isolating lines with pressure testing, then pinpointing the spot with moisture meters, thermal imaging, acoustic listening equipment and drain cameras. That lets us open only the small area where the leak actually is.
What are the signs of a slab leak?
Common signs are an unexplained rise in the water bill, warm or damp spots on a floor, the sound of running water when fixtures are off, cracked flooring and mould or musty smells near floor level.
Who is responsible for a leak between condo units in Florida?
It depends on where the leak starts and what your association's declaration says about unit and common elements, so the first step is finding the exact source. We document the source and repair so the association, owners and insurers can apply the governing documents to the facts.
How much does leak detection cost?
Cost depends on the size of the building, the number of lines to test and how hard the area is to access. We quote the detection work before starting and quote the repair once the source is found.
Is a water leak an emergency?
Yes, if water is actively escaping into the building. Damage and mould risk grow by the hour, so active leaks get 24/7 dispatch.
