Non-Invasive Leak Detection & Moisture Mapping in Portland, OR
Many of the most destructive water events in Portland properties begin as slow, hidden leaks behind walls, under floors, or above ceilings, often showing up only as faint musty odors or minor discoloration months later. Finding the precise source of this hidden moisture without resorting to tearing out entire sections of finished material requires highly specialized equipment and technical expertise. Ignoring these chronic, hidden leaks is extremely dangerous, as they lead directly to structural compromise, elevated energy bills, and widespread, costly mold contamination.
Our Leak Detection & Moisture Mapping services utilize cutting-edge, non-invasive technology to pinpoint the exact location of water intrusion. By using high-resolution thermal imaging cameras, sensitive electronic moisture meters, and non-penetrating sensors, our IICRC-certified technicians can accurately map the precise path and extent of moisture migration within your structure. This advanced, accurate detection ensures that we can stop the source immediately and confine the necessary demolition and repair work only to the smallest, most targeted area possible, saving you significant time, money, and unnecessary disruption to your Portland home or business.
REVIEWS
Dorianna PhillipsTrustindex verifies that the original source of the review is Google. I cannot recommend 911 Restoration highly enough. When my basement flooded, their team was at my home within hours and immediately took action to address the damage. My rep, Richard Brown, was exceptional. He is clearly experienced and knowledgeable, but what stood out even more was his empathy and calm approach. I was panicked, and he took the time to walk me through every step of the process, laying out the issues and solutions clearly. He even spoke directly with my insurance agent, which made the entire process much easier for me. Richard’s team, including George and Melvin, were equally outstanding. They were professional, kind, and thorough. Every person I interacted with from 911 Restoration demonstrated the same level of care and professionalism. They turned what could have been a nightmare into a manageable experience, and I walked away with total confidence in their work. If you are facing water damage or any restoration issue, 911 Restoration is the company you want by your side. They are responsive, compassionate, and true experts in what they do. Jennifer OrtizTrustindex verifies that the original source of the review is Google. We can't thank the entire crew and staff for their concern and service. The job definitely started with finding out why our floor was warping and where the water was coming from. The reassurance that they would take care of contacting contractors to handle the plumbing that needed to be dealt with, the flooring and cabinetry that needed to be replaced was such a relief for us. First though they had a lot of work to deal with under our house before they could even start inside - hot water breaks cause so much immediate damage. These guys worked so hard and continuously getting all the insulation under one side of our house removed so they could expose the pipes and find what needed to be done before the plumber got here. The multiple days of drying, and finding they needed more fans were needed to get this dried out. They always had such a great and caring attitude, took great care in keeping our house as closed off from the mold exposure as possible. Since we have a number of pets we didn't want them to be boarded so we chose to stay here while they worked. They never once let on this was more inconvenient for them than not. They understood the stress both animals and humans were having here. Not that I ever want to go through this again, but if I had to we would call 911 first. You folks are awesome from day 1 to the finish. Taylor BeggTrustindex verifies that the original source of the review is Google. Our sewage line backed up TWICE and turned into a total nightmare. We were really nervous because after getting quotes and schedules from 3 other companies, we were losing hope that nobody would be able to help us. These people absolutely nailed it!!! Fair pricing, exceptional level of detail to their work, and they were so polite and courteous around our home. Richard who came and gave us a quote was kind and professional, and his crew that did the cleaning, Alex and another man with a script tattooed on his arm, were literally so nice we were raving about them after they left. Most polite and respectful workers we’ve ever had in our home and we would have them back in a heartbeat. THANK YOU!! Nicolas MaximTrustindex verifies that the original source of the review is Google. We had a recent water leak from our second floor down into our first floor and into the crawl space! Rich did an amazing job telling me what I could expect during the mitigation phase (cost, visits, materials, and equipment needed). Mel, Scott and the team did an amazing job daily coming to set up equipment for drying the damaged areas and ensuring that things were progressing. Very friendly, courteous, and professional. Would highly recommend if you’ve had a leak and are in need of mitigation. Bella DvirTrustindex verifies that the original source of the review is Google. We received quick response and service. they worked with our insurance company. Very satisfied. Chris HerrinTrustindex verifies that the original source of the review is Google. 911 restoration of Portland turned an extremely negative situation into one where I felt empowered to make informed decisions. Aurelius showed up with an hours of my phone call and I felt like a high priority. They worked with me to address my needs and my concerns. I would highly recommend you consider using them if you find yourself in a similar situation. They understood my financial limitations and worked with me to find a solution that worked within those constraints, without making me feel pressured to take on more than I could afford. Not only was their team in the field, upbeat and friendly, but the owner Moe reached out to me personally to see if he couldn’t make it even better. I very much appreciate their approach and their prompt response. Lyndsay MaderisTrustindex verifies that the original source of the review is Google. I can’t recommend 911 Restoration enough! After my salon flood, they showed up incredibly fast and handled every step of the remediation process with total professionalism. As a woman, I don’t always have the best experiences with contractors, but their team made me feel completely comfortable and earned my trust from day one. The entire process was smooth, stress-free, and handled with great care. I’m beyond grateful for their help—highly recommend! Rosalie WakefieldTrustindex verifies that the original source of the review is Google. In our home, the washing machine and dryer are in the center of the house. Imagine my surprise when I looked up from the computer and saw a flood of water working its way toward me. I contacted 911 Restoration and they came right out with several de-humidifiers and heater/dryers, put them everywhere, even in the crawl space, and let them do their thing for a few days until everything was dried out nicely. They had to take a lot of the carpet out, too. Then they called Portland Construction Solutions to come and do all of the hammerin' and nailin', install new carpet, everything back to normal, even fixed the drain where the hose had popped out. I was SO impressed with how they kept in close touch with me, explained the process. I definitely recommend both businesses for any one who might have a similar problem. Excellent job - nice people! Tricia JenkinsTrustindex verifies that the original source of the review is Google. I’ve owned homes since 1989 and had never filed a claim or had a disaster of any kind. When I woke on one Sunday morning, to find I had a water leak that went from the top floor to the bottom floor, on through to the crawl space , I had no idea who to call or what to do. I was panicked!! Not only did 911 Restorations on call team, call me back immediately, they sent Richard out to save the day and my house from further damages. Their team began water extraction, carpet and lower wall removal, a ceiling opened up, and had dehumidifiers and fans going within a day. There was no way mold was setting in with their fast response and action. Not only did they get into action, they walked and talked me through step my step exactly the process that I could expect and what they said was exactly what took place. It was so reassuring to know they were knowledgeable and I could trust them in a situation I didn’t know anything about. In addition to the mitigation, they scheduled my move out so I could begin my restoration process with ease. Moe and the billing office were so patient with me when I had some issues with an insurance mixup causing a delay in payment. Thank you 911 for your professionalism, your compassion in a panicked situation, your knowledge so I could stay calm, knowing you had this covered, and your extreme patience!! I hope no one has a disaster, but if they do, I’m recommending you without a doubt. William KiefelTrustindex verifies that the original source of the review is Google. 911 Restoration was fast, accurate, on time and very customer service oriented. Every employee was great to work with. 911 worked well with my insurance company too. Highly recommend these guys.
Our 3-Step Detection & Mapping Process
Initial Assessment and Thermal Imaging Scan
We perform a complete visual inspection and then conduct a full thermal scan of the affected area. This uses high-resolution cameras to detect minute temperature differentials caused by moisture hidden behind surfaces, providing a clear visual map of the saturation.
Pinpoint Detection with Non-Invasive Meters
We use sensitive, non-penetrating and penetrating electronic moisture meters to confirm the thermal findings and determine the precise saturation level within materials like wood and drywall, verifying the path of the water with forensic accuracy.
Source Identification & Remediation Plan
We conclusively identify the point of water intrusion (e.g., specific pipe section, failed roof flashing, leaky window seal) and deliver a detailed, documented report and comprehensive remediation plan, ready for immediate repair and structural drying.
Q&A
How does thermal imaging technology help you find a leak that I can't see on the surface?
Thermal imaging cameras detect differences in surface temperature. Since water has a much lower temperature than dry structural materials, a thermal camera can reveal cooler areas behind walls or ceilings where water has collected or is actively flowing. This provides a non-destructive way to visualize the location and extent of moisture that would otherwise remain hidden until significant secondary damage, like mold or collapse, occurs.
Is your leak detection service truly "non-invasive," meaning you won't tear up my walls or floors to find the leak?
Yes, our primary leak detection and moisture mapping process is designed to be completely non-invasive, meaning we typically do not have to cause any initial damage to your property to find the leak. We rely on exterior tools like thermal cameras, acoustic sensors, and non-penetrating moisture meters. Once the source is accurately pinpointed, we may only need to make a small, precise incision to confirm the source or access the damage, minimizing the overall reconstruction required.
Can your moisture mapping process find the source of an unexplained musty or moldy odor in my home?
Absolutely. A persistent musty smell is one of the most common indicators of hidden water damage and mold growth in Portland properties. Since moisture mapping traces the path of water saturation, it inevitably leads us to the source of the dampness that is feeding the mold colony, even if the contamination is entirely contained within a wall cavity or under a floor. Once we locate the hidden moisture, the mold source is generally confirmed.
What is the benefit of mapping the moisture extent and not just finding the leak source?
Finding the source (the broken pipe) only tells us where the water originated. Mapping the extent tells us how far the water traveled through materials like wood, drywall, and insulation, which is critical for successful restoration. If we only fix the pipe and don’t address the full extent of the saturation, the hidden wet materials will breed mold, leading to an immediate failure of the repair and requiring another costly remediation service later on.
Do the results of your detection service provide documentation I can use for an insurance claim?
Yes. The detailed report we generate from the leak detection and moisture mapping process includes photographic evidence (both standard and thermal images), precise moisture readings from electronic meters, and a clear diagram illustrating the source and the extent of the water migration. This comprehensive, technical documentation is professional-grade and serves as crucial, undeniable evidence required by insurance adjusters to substantiate the full scope of your claim.
