Window Rain Leak Testing in Los Angeles

With so many window manufacturers, materials and installation types, it's extremely difficult for most contractors to know how to properly perform water intrusion tests to effectively locate rain leaks. I'll take it a step further and add that many contractors who are not water intrusion experts still think that a water hose is the best way to replicate rainfall. When is the last time you saw rainfall in the same volume and pressure that a water hose can? Probably never.

Spray Rack With Interior Pressure to Find Rain Leaks in Windows

That's because a water hose produces water pressures that no normal rainfall in Los Angeles can produce. The force of a water house is too great of a pressure that should never be applied to a wall, a window or door to see if it leaks. There are far better options available to the professional testing agency to procure leaks in these systems.

The use of a water hose is absolutely not the appropriate method in locating water intrusion leaks here in Los Angeles and abroad. In fact, there are only a few methods acceptable and used to locate water intrusion leaks, and only a professional can administer these tests using this equipment.

A spray rack is essentially a large 8' x 8' square which has multiple water nozzles placed within these bars. The water pressure applied while using this rack is close to what would be considered typical rainfall. If pressure is needed to simulate wind, then a chamber is constructed on the inside of the window, wall  or door system with plastic and a vacuum is used to pull pressure across the specimen.

  • Identifying Signs: Look for water stains, peeling paint, mold growth, or condensation around windows. These indicate potential moisture intrusion.
  • Exterior Inspection: Check the window frame, caulking, and seals for gaps, cracks, or deterioration. Pay attention to the flashing, which helps redirect water away from the window.
  • Interior Inspection: Look for moisture, stains, or rot on the interior walls or window sills. Check for drafts or unusual odors, which could signal hidden moisture.
  • Testing Methods: Employ spray rack testing or simulated rain chambers to replicate real rain conditions and identify leaks or weak points.
  • Repair and Maintenance: Seal any gaps or cracks with appropriate caulking or weather-stripping. Replace damaged seals or flashing. Ensure proper drainage systems are in place.
  • Professional Help: Consider hiring a professional inspector or contractor experienced in moisture intrusion detection and repair for a thorough assessment.
  • Preventive Measures: Regularly inspect and maintain windows, especially before rainy seasons. Ensure proper ventilation in the home to reduce condensation.

Available Methods for Testing Window Rain Leakage

Like most water intrusion issues  there are basic methods to determine the origin of the water intrusion. When it comes to rain leakage, these are a few of the methods we use to on a regular basis to locate the source of the water ingress.

AAMA 501.2 hand-held spray wand test

This specific test involves spraying a hand held wand with a specific nozzle at fixed storefront windows at a specific pressure for a specific duration of time. Observers check for any leaks or water ingress. This the of window water intrusion leak test is performed on commercial buildings, however, there are some residential applications for this test as well.

Spray Rack Testing

The spray rack is a tool used by most professionals in the water intrusion testing and rain leak detection industry. The rack utilizes a system that evenly distributes water over the window at a specific pressure and angle, simulating rain conditions. This method allows for controlled and easily replicated testing.

Pressurized Chamber Testing

The use of a pressurized test chamber involves placing the entire window or window assembly in an air-tight chamber where rain conditions can be replicated accurately. This method provides controlled and precise testing. These are the industry test standards we use to recreate water leaks, moisture intrusion or rain leak testing throughout Los Angeles and southern California.

Thermography water intrusion testing

Thermography is the use of a camera that allows the testing agent to view indications of moisture within wall surfaces and ceiling surfaces without having to remove wall covering. Here in Los Angeles, water leaks in residential homes and commercial buildings are extremely common, so the immediate access to indications and signs of water within wall surfaces is critical and the use of thermography is the way to achieve this.

Field moisture intrusion Testing

Conducted on-site during or after construction to assess the window’s performance in real conditions. Professionals simulate rain or use natural rainfall to observe any leakage.
Each method offers distinct advantages and may be chosen based on factors like accuracy, control, or the specific requirements of the window being tested. Professional inspectors or window manufacturers often employ these methods to ensure window integrity against rain infiltration.
