Thermal Imaging Leak Detection in Los Angeles
You know water is getting in, but you cannot see where. Absolute Maintenance & Consulting uses FLIR thermal imaging cameras to detect hidden water leaks behind your walls, ceilings, and floors without cutting a single hole. Thermal imaging (also called infrared leak detection) identifies moisture that is invisible to the naked eye by detecting the temperature differences that trapped water creates inside building materials.
Our water intrusion investigation team uses thermal imaging as the first diagnostic step on every inspection. Cameron Figgins, founder of Absolute Maintenance & Consulting, has over three decades of experience reading thermal signatures in Los Angeles buildings. We hold IICRC certification (#70018676), MICRO certification, and CSLB license #998184.
Thermal imaging is included in every building envelope inspection at no additional cost. Standalone thermal imaging scans start at $350, credited toward your water intrusion repair.
Can Thermal Imaging Detect Water Leaks?
Yes. Thermal imaging cameras detect water leaks by reading infrared radiation emitted by surfaces. When water saturates building materials like drywall, wood framing, or insulation, the wet area cools through evaporation. That temperature difference, even as small as 1 to 2 degrees Fahrenheit, shows up clearly on a thermal image as a distinct color pattern against the surrounding dry material.
Thermal imaging detects water leaks that you cannot see or feel through finished surfaces:
- Moisture trapped behind drywall from roof leaks that traveled along rafters before reaching the ceiling
- Water migrating inside wall cavities from stucco failures or window flashing breakdowns
- Foundation moisture rising through concrete slabs and saturating interior finishes
- Residual moisture from previous leaks that was never properly dried, creating hidden mold growth conditions
- Active drips inside wall cavities during or immediately after rain events
The critical advantage of thermal imaging is that it reveals the full extent of water migration, not just the visible stain. A 6-inch water stain on your ceiling may have a 6-foot moisture pattern behind the drywall. Without thermal imaging, you would never know how far the water traveled or where it actually entered the building.
How We Use Thermal Imaging to Find Your Leak
At Absolute Maintenance & Consulting, thermal imaging is one tool in a multi-step diagnostic process. We do not just take thermal photos. We interpret what the thermal signatures mean, confirm them with moisture meter readings, and trace every moisture pattern back to its source.
|
Step |
What We Do |
Why It Matters |
|
1. Exterior Assessment |
Walk the entire building perimeter. Identify visible deficiencies in roofing, cladding, flashing, and sealants. |
Thermal imaging tells us WHERE water is. The exterior assessment tells us HOW it got there. |
|
2. Interior Thermal Scan |
Systematically scan every wall, ceiling, and floor surface with FLIR cameras. Document all thermal anomalies. |
Creates a complete picture of all moisture locations in the structure, not just the areas where you see damage. |
|
3. Moisture Meter Confirmation |
Test every thermal anomaly with pin and pinless moisture meters. Record quantitative moisture readings. |
Thermal anomalies can have causes other than moisture (insulation gaps, air leaks). Moisture meters confirm which anomalies are water. |
|
4. Moisture Source Tracing |
Follow the moisture pattern from the interior damage back to the building envelope breach. |
Fixing the stain without fixing the source means the leak returns. We trace every moisture path to its origin. |
|
5. Documentation |
Annotated thermal images paired with regular photos, moisture readings, and identified entry points. |
Your report shows exactly what we found, where the water is, and what caused it. |
This process typically takes 2 to 3 hours for a single-family home. We scan the entire structure, not just the room where you see the problem. Water can travel 10 to 20 feet from the entry point before it shows up as visible damage.

Residential Thermal Imaging Leak Detection
If you are a homeowner in Los Angeles dealing with a water stain, musty odor, or suspected leak, thermal imaging gives you answers without tearing your walls apart. Here are the most common residential scenarios where we deploy thermal imaging:
After rain events. You notice a new stain after a storm, but the leak is not obvious. Thermal imaging during or shortly after rain reveals the active moisture path through your building envelope.
Recurring leaks that contractors cannot find. You have had someone patch the roof or re-caulk the window, but the leak keeps coming back. That happens when the visible damage is far from the actual entry point. Thermal imaging maps the entire moisture trail and locates the real source.
Pre-purchase inspections. Standard home inspections do not include thermal imaging. Before you close on a property in Los Angeles, thermal imaging reveals hidden moisture behind walls and under floors that could mean thousands in water intrusion repairs.
Post-fire properties. After a building fire, firefighting water saturates walls, ceilings, and floors. Thermal imaging identifies every moisture pocket so your fire damage restoration team knows exactly what needs drying and where mold is likely to develop.
Mold investigations. You smell mold but cannot see it. Thermal imaging locates the hidden moisture feeding the mold, which is the critical first step in any mold inspection.
Commercial Thermal Imaging Leak Detection
Commercial buildings in Los Angeles present unique challenges for leak detection. Large roof areas, curtain wall systems, multi-story facades, and concealed mechanical spaces make visual detection nearly impossible. Absolute Maintenance & Consulting provides thermal imaging services for:
- Office buildings where water intrusion behind exterior cladding or above drop ceilings goes undetected until it reaches tenant spaces. We scan entire floor plates to map moisture migration.
- Multi-unit residential where a single building envelope failure can send water into multiple units. Thermal imaging documents the moisture path for HOA boards, property managers, and insurance adjusters.
- Retail and restaurant spaces where water stains in customer-facing areas require urgent identification and repair. Thermal imaging pinpoints the source so repairs target the right location the first time.
- Warehouses and industrial buildings with large flat roof areas. Thermal imaging identifies ponding water and membrane failures across thousands of square feet in a fraction of the time it takes to visually inspect.
- New construction warranty claims where suspected defects need documented evidence. Thermal images provide clear visual proof of moisture presence behind finished surfaces.
Commercial thermal imaging reports from Absolute Maintenance & Consulting include annotated images, moisture readings, identified entry points, and recommendations formatted for insurance claims, property management reports, and construction defect evaluations.

What Thermal Imaging Can and Cannot Detect
Thermal imaging is a powerful diagnostic tool, but it has specific capabilities and limitations. Understanding both helps set accurate expectations.
|
Thermal Imaging CAN Detect |
Thermal Imaging CANNOT Detect |
|
Active moisture behind walls, ceilings, and floors |
The exact species of mold present (requires lab testing) |
|
Hidden water migration paths through building materials |
Moisture deep inside concrete slabs thicker than 6 inches |
|
Missing or displaced insulation (appears as cold spots) |
Water in pressurized plumbing pipes (that is plumbing leak detection) |
|
Air infiltration points (drafts around windows and doors) |
Historical water damage that has completely dried out |
|
Moisture in roofing assemblies and flat roof membranes |
Leaks that only occur under specific wind-driven rain conditions (use ASTM E1105 for that) |
|
Radiant heating system leaks beneath flooring |
Structural integrity of water-damaged framing |
When thermal imaging alone cannot confirm a leak source, we deploy additional methods. ASTM E1105 water testing simulates rainfall on specific wall sections to reproduce leaks that only occur under rain exposure. Moisture mapping with pin and pinless meters provides quantitative moisture data at specific points. We use the right tool for each situation.

Why Choose Absolute Maintenance & Consulting for Thermal Imaging?
We read thermal images. We do not just take thermal photos. Anyone can buy a FLIR camera and point it at a wall. Interpreting thermal signatures in Los Angeles buildings requires understanding local construction methods, building materials, and the way water moves through stucco wall assemblies, clay tile roofing systems, and slab foundations. Cameron Figgins has over three decades of experience interpreting these patterns.
Thermal imaging is step one, not the entire process. We confirm every thermal anomaly with moisture meters and trace every moisture pattern back to its building envelope source. A thermal image tells you that water is present. Our investigation tells you why it is there and how to stop it.
Non-destructive investigation. We find what is behind your walls without opening them. When exploratory openings are needed, we discuss them with you first and only proceed with your approval.
Your scan fee is credited toward repair. Your $350 investment applies directly to your water intrusion repair cost. The scan is the first step, not a separate expense.
Frequently Asked Questions
Can thermal imaging detect leaks behind walls?
Yes. Thermal imaging cameras detect temperature differences caused by moisture trapped inside wall cavities. Wet drywall and framing cool through evaporation, creating a distinct thermal signature visible on the camera. Absolute Maintenance & Consulting uses FLIR cameras to scan your walls and identify hidden moisture without removing drywall or making holes.
How much does thermal imaging cost for water leak detection?
Residential inspections start at $450. That fee covers thermal imaging, moisture mapping, full documentation, and a written report. The $450 is credited toward repair work if you hire us. Commercial pricing depends on building size, number of stories, and the scope of investigation. Call (310) 678-4345 for a commercial quote.
How long does a thermal imaging leak inspection take?
A residential thermal imaging scan takes 2 to 3 hours for a single-family home. We scan the entire structure, not just the room with visible damage, because water often travels far from the entry point. Commercial scans take 3 to 6+ hours depending on building size.
Is thermal imaging accurate for finding water leaks?
Thermal imaging is highly accurate for detecting the presence and extent of moisture behind finished surfaces. It detects temperature differences as small as 0.1 degrees Fahrenheit. We confirm every thermal anomaly with moisture meter readings because temperature differences can have causes other than water (insulation gaps, air infiltration). The combination of thermal imaging and moisture meters provides a confirmed, documented diagnosis.
Can a thermal camera find a roof leak?
Yes. Thermal imaging detects moisture in roof decking, insulation, and ceiling assemblies caused by roof leaks. For flat roofs, thermal imaging can scan large areas quickly to identify where water has entered the roofing membrane. For sloped roofs, we scan the underside from the attic space and the interior ceilings to map where water has traveled after entering.
Do I need thermal imaging or a plumber?
If your leak happens during or after rain, or if water stains appear on exterior walls, you likely have a building envelope leak and need water intrusion investigation. If your leak happens regardless of weather, runs constantly, or is near plumbing fixtures and pipes, you likely need a plumber. Absolute Maintenance & Consulting specializes in exterior water intrusion. We investigate leaks caused by roof failures, stucco breaches, window flashing failures, and foundation issues. We do not do plumbing work.
If you are buying property in Los Angeles, a building envelope inspection is strongly recommended. Standard home inspections do not include thermal imaging, moisture mapping, or water testing. Hidden water intrusion behind stucco, in crawl spaces, and around windows is common in LA construction and can mean thousands of dollars in repairs that a standard inspection misses. A pre-purchase building envelope inspection gives you the information you need to negotiate repairs or walk away.
