Water Leak Detection & Water Intrusion Testing in Los Angeles

Find the Source. Stop the Damage.


Water intrusion doesn't always enter where the damage appears. Water can travel behind walls, through building assemblies, along window frames, and through failed sealants before becoming visible inside a building.


American Rope Access provides professional water leak detection and water intrusion testing for commercial, multi-unit, high-rise, and difficult-to-access buildings throughout Los Angeles and Southern California.


Our systematic testing process is designed to help identify where water is entering, isolate the likely source, and provide clear documentation so the appropriate repair can be made.

Water Leaks Are Often Harder to Find Than They Appear


A ceiling stain or wet wall may be the result of water entering several feet—or even several floors—away from the visible damage.

Common sources of water intrusion include:

  • Failed window seals and perimeter joints
  • Curtain wall and storefront systems
  • Deteriorated caulking and sealants
  • Cracks and openings in exterior façades
  • Roof-to-wall transitions
  • Skylights and architectural glazing
  • Expansion joints
  • Penetrations and exterior openings
  • Improperly sealed building components
  • Areas affected by wind-driven rain


Rather than relying on guesswork, ARA uses a systematic approach to investigate suspected water entry points.


Our Water Leak Detection Process


1. Visual Inspection

We begin by evaluating the suspected leak area from both the interior and exterior when accessible.

Our technicians look for visible signs of water entry, failed sealants, cracks, gaps, deteriorated materials, staining, and other conditions that may contribute to water intrusion.

We also consider the building's construction and the way water could travel through the exterior assembly.


2. Controlled Water Testing

Once potential entry points have been identified, we perform controlled water testing to help isolate the source.

Rather than simply spraying an entire façade, testing is performed systematically on suspected areas while the interior is monitored for signs of water penetration.

This allows us to narrow down the likely entry point and distinguish between multiple possible sources.


3. Moisture Detection & Thermal Imaging

Not all water intrusion is visible.

Moisture meters and thermal imaging can help identify areas of elevated moisture and temperature differences that may indicate hidden water intrusion.

These tools provide additional information when investigating leaks that are concealed behind finishes or building components.


4. Documentation & Findings

We document the investigation with photographs, observations, moisture readings when applicable, and testing results.

Our findings help property owners, managers, contractors, and building professionals understand:

  • Where water is likely entering
  • Which building components may be contributing to the problem
  • What areas were tested
  • What conditions were observed
  • What repairs or further investigation may be appropriate

Difficult-Access Water Leak Detection

Finding the Leak Where Others Can't Reach


Some of the most difficult leaks originate from areas that are inaccessible from the ground.

High-rise windows, curtain walls, façades, skylights, architectural features, and upper-level joints may require specialized access simply to inspect the suspected source.

That's where American Rope Access has an advantage.

Our trained rope access technicians can safely reach elevated areas that may otherwise require scaffolding, swing stages, or aerial lifts.

This allows us to investigate difficult-to-access areas while minimizing equipment, setup time, and disruption to building occupants.


Rope Access Can Help Us Reach:

  • High-rise windows
  • Curtain wall systems
  • Exterior façades
  • Skylights and atriums
  • Expansion joints
  • Parapets and roof transitions
  • Difficult-to-access sealant joints
  • Architectural features
  • Other elevated building-envelope components


More Than Leak Detection

We Can Help Address the Source


Finding the source is only part of solving a water intrusion problem.

When our investigation identifies a repairable issue such as failed sealant, deteriorated caulking, or an accessible exterior opening, American Rope Access can often perform the necessary sealing or waterproofing repair.

This gives property owners and managers the option of working with one contractor from investigation through repair.


Depending on the findings, repairs may include:

  • Joint and perimeter caulking
  • Sealant replacement
  • Exterior waterproofing
  • Localized sealing
  • Window perimeter sealing
  • Building-envelope repairs

Frequently Asked Questions


How do you find the source of a building leak?


We begin with a visual inspection and then use controlled water testing to investigate suspected entry points. Moisture meters and thermal imaging may also be used to help identify hidden moisture and trace potential water paths.


Can you test windows for water leaks?

Yes. We can investigate suspected leaks around window frames, perimeter sealants, joints, storefront systems, curtain walls, and adjacent building materials.


Can you find a leak on a high-rise building?

Yes. Our rope access capabilities allow our technicians to reach many elevated areas without relying exclusively on scaffolding or aerial lifts.


Do you only find the leak, or can you repair it?

When the source is a repairable exterior condition, ARA may also provide caulking, sealing, and waterproofing repairs.


What if the leak is not visible?

That is common with water intrusion. Water can travel through building assemblies before appearing as an interior stain or moisture problem. Moisture detection, thermal imaging, and controlled testing can help investigate concealed sources.


Do you provide documentation?

Yes. Depending on the scope of the investigation, we can provide photographs, observations, moisture readings, and documented findings to help identify the likely source and determine appropriate next steps.


Do you serve residential properties?

Our primary focus is commercial, multi-unit, and complex building-envelope investigations, but we can evaluate residential projects depending on the building and scope.
