Service Overview
What Is Balcony Leak Detection?
Quick answer
Balcony leak detection is the process of finding where water passes through an upper-level balcony, typically through cracked tile and grout, a failed waterproof membrane, drains, door thresholds or wall connections, and into the structure and ceilings below, so the specific failure can be repaired instead of repeatedly resealing the surface.
Balcony leaks are especially frustrating for homeowners. You may have tried various methods of sealing the balcony and it still leaks when it rains, leaving you wondering what else to try and worried about the cost. Upper-level balconies tend to leak into the rooms and ceilings below, and the damage often appears far from the actual failure.
We have fixed hundreds of balcony leaks, especially on upper-level balconies that leak into the space below. The key is finding where the water actually gets through before any repair is made.
We locate the leak, explain what failed and tell you the total cost of any repair before repair work begins.

Why Balconies Leak
Why Do Upstairs Balconies Leak?
Most balconies are built with a wood structure, covered with a waterproof membrane, and then finished with tile or stone laid on top. Tile and stone are rigid and do not flex. When the wood beneath moves and bends, it compromises the waterproofing, and the tile and grout crack. Water then seeps through those cracks, past the damaged membrane and down into the interior of the house.
Three money-saving steps to get to the bottom of a balcony leak
- Locate the leak first. Confirm where water is getting through before deciding on a repair.
- Open the water-damaged ceiling below the balcony where needed to assess and repair the damage.
- Repair, then leak test again before covering up the ceiling, so you know the repair worked before the finishes go back on.
Waterproofing options
Properly waterproofing tiled and stone balconies is the best way to stop leaks. A waterproofing system that tolerates the expansion and contraction of the wood structure helps protect the building from water damage. Which option is right depends on how the balcony is built and what failed.
Tell us what has already been tried. We will explain how we would find where the water gets through.

How We Find a Balcony Leak
Inspect Above & Below
We inspect the balcony surface, drains, thresholds and walls, and the damage below.
Map the Moisture
Moisture readings and thermal imaging show where water is reaching the structure.

Controlled water testing of specific areas confirms where water passes through.
Explain the Repair
You learn what failed and the total cost of repair before any repair work begins.
Detection Methods
Finding Where Water Gets Through
Testing one area at a time tells us whether the problem is the surface, the drain, the threshold or the wall connection.
Controlled Water Testing
Water is applied to specific areas one at a time to see which one leaks below.
Thermal Imaging
Reveals wet areas in the ceiling and structure below the balcony.
Moisture Readings
Confirms how far water has spread through framing and drywall.

Why It Matters
Why Professional Balcony Leak Detection Saves Money
- Stop repeated resealing. Surface sealers do not fix a failed membrane, drain or threshold.
- Protect the structure. Wood framing under a leaking balcony can rot, which can become a safety concern.
- Limit interior damage. Finding the leak early protects ceilings, walls and finishes below.
- Multi-unit buildings. In condos and HOAs, balcony leaks often affect a neighboring unit. Clear findings help everyone understand the source.

Why does my balcony leak into the room below?
Most balconies have a wood structure, a waterproof membrane and rigid tile or stone on top. When the wood flexes, the membrane is compromised and the tile and grout crack, letting water seep through into the space below.
Why does my balcony still leak after sealing it?
Surface sealers cannot repair a failed membrane, drain or door threshold. If the waterproofing beneath the tile has failed, the leak continues until that failure is located and repaired.
How do you find a balcony leak?
We inspect the balcony and the damage below, map moisture with meters and thermal imaging, and use controlled water testing on specific areas to confirm where water passes through.
Should the ceiling below be opened?
Often, part of the water-damaged ceiling below needs to be opened to assess and repair the damage. We recommend leak testing the repair again before the ceiling is closed up.
Can a balcony leak damage the structure?
Yes. Long-term leaks can rot the wood framing that supports the balcony and the ceiling below, which can become a safety concern.
