Professional Basement Water Damage Cleanup in Portland, OR
Basements and underground spaces are the most vulnerable parts of any structure in the Portland area, frequently suffering water damage from common issues like sump pump failures, persistent foundation seepage, or severe storm flooding. Because basements are inherently cooler and more humid than the rest of the home, water damage down below creates an extremely high risk for rapid and extensive mold growth, severely affecting the indoor air quality and structural integrity of your property. This makes immediate, professional intervention essential for the health and safety of your entire building.
Our Basement Water Damage Cleanup service is specifically designed for the complexities of subterranean drying and concrete structures common in the Portland region. Our IICRC-certified technicians use industrial-grade dehumidifiers and air movers strategically to address the concrete’s high retention rate of moisture, ensuring deep structural drying. We handle the full process: rapid extraction, debris removal, professional-grade sanitization, and meticulous structural drying, guaranteeing your basement is not just dry on the surface, but dried completely to industry standards to prevent future mold issues and restore the space to a safe, usable condition.
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 Basement Cleanup Process
Emergency Water Extraction & Debris Removal
We prioritize safety (especially electrical hazards) and rapidly extract all standing water, often using submersible pumps for high-volume removal. We then carefully remove any contaminated or non-salvageable contents and debris from the entire basement space.
Subterranean Structural Drying & Dehumidification
We set up specialized drying equipment, including powerful low-grain refrigerant (LGR) dehumidifiers, to effectively draw deep-seated moisture out of the dense concrete and foundation materials common in Portland basements, which retain water for long periods.
Mold Prevention, Sanitization, & Restoration Planning
Once verified as completely dry using moisture meters, we thoroughly sanitize the entire space to prevent mold and prepare a detailed plan for reconstruction, which may include foundation sealing, or repairing flooring and walls.
Q&A
Why is drying a basement so much more difficult and specialized than drying an upstairs room?
Basement drying is fundamentally harder because concrete is extremely porous and acts like a massive sponge, absorbing and holding onto moisture for extended periods, and the lower air temperature naturally slows evaporation. To overcome this, we use specialized equipment like LGR dehumidifiers and targeted airflow to create a low-humidity, high-heat environment that forces the moisture out of the concrete and the framing, ensuring the space is dried to a structurally sound and mold-free level.
What are the tell-tale signs of a failing sump pump that could lead to basement flooding?
Warning signs that your sump pump may fail include hearing unusual noises like grinding or rattling, noticing the pump running continuously or not at all, or seeing standing water around the base of the pump. Furthermore, if the pump is over seven to ten years old, or if the float switch is stuck or clogged with debris, its reliability is compromised, which signals that it needs maintenance or replacement before the next heavy Portland rainstorm hits.
What specific steps do you take to address the high risk of mold in a damp basement environment?
Given the high humidity and darkness of most basements, our process is hyper-focused on mold prevention. This involves removing any non-salvageable porous materials immediately, ensuring the structure is dried quickly and thoroughly to less than 16% moisture content, and applying a professional-grade antimicrobial agent to all exposed structural surfaces to kill any spores and inhibit future fungal growth before any reconstruction begins.
Can water seepage through the concrete foundation be cleaned up, or does it require foundation repair?
While we can certainly clean up and dry the resulting interior water damage from seepage, the seepage itself is a sign of a foundation or drainage issue that requires external or internal waterproofing repair to fix permanently. Our restoration work addresses the interior damage, but we will also identify the source of the seepage and recommend necessary external solutions, such as correcting yard grading or installing a French drain, to ensure the problem does not recur.
Does your cleanup service include removing and disposing of damaged personal items and debris from the basement?
Yes, our comprehensive service includes the careful sorting, inventory, and removal of all damaged personal belongings, debris, and non-salvageable building materials, such as saturated drywall and carpeting. We handle the proper and safe disposal of these materials, including any items contaminated by sewage or flood water, and provide you with a detailed list of non-salvageable contents that is essential for submitting your insurance claim.
