Crawlspace Ninja just finished up with the second project I've had them complete at my house and I'm completely happy with my decision to have them back. The first project they did for me was to seal all my crawlspace vents and install a dehumidifier with drain and crawlspace fan to keep bring the moisture level down and keep it down. It has worked really well. When I open my crawlspace door I no longer have that crawlspace smell (damp, musty, or however you describe it) and the air in my home feels different to the point that I am comfortable with my thermostat set at two degrees higher than it used to be. I wasn't expecting a change in how my house felt, it was just an unexpected bonus. I had this work completed only because the damp smell had me curious if I had a moisture problem. On the initial visit for them to check out the space Jamie explained to me exactly what was going on (no sky is falling sales pitch) and explained what I needed to do and other options that would make the space even better but were not needed right away. I scheduled the work to be done and it was completed on time for the exact price we discussed and the crew was very professional, did great work, and cleaned up after themselves. And last, the price was very reasonable. I was so satisfied with the work in my crawlspace I had them come back to do some work in my attic. My home has a loft bedroom that has always been warmer than the downstairs of the home. After some looking around I noticed the two knee walls between the loft and attic were not insulated. To see how much temperature difference, I had I used an infrared thermometer to check some temperatures in my house. I did these checks multiple times over the course of a week or so. I checked the temperature of the wall beside my thermostat downstairs and found the wall to always be within 1 degree +/- the temperature my thermostat was set to. In addition, every downstairs wall in my house was always within 2 degrees +/- the temperature of my thermostat. But the knee walls between the loft and attic were consistently between 10 and 12 degrees hotter that my thermostat temperature. Crawlspace Ninja came out and insulated my knee walls with fiberglass bats covered with foam board insulation and air sealed the wall. Since the work has been completed the knee walls have stayed within 1 to 2 degrees +/- the temperature my thermostat is set to and the upstairs is now just as comfortable as the rest of my house. They also sealed all of my HVAC registers to the floor both from the crawlspace and living space and relocated my dryer vent that had been venting under a low deck to a wall that was free of obstructions. Again, Jamie showed up on time to take a look, make a recommendation and give me a quote. The work was scheduled and the crew showed up on time, did a great job, and cleaned up after themselves then made sure I was satisfied with the work. The price on this job was so reasonable I actually questioned Jamie about the price because it seemed to low and I wanted to ensure we were on the same page with what all I wanted done. I've got several of the projects I want to get done in time and I'll definitely be having the Ninjas back to do them. I give them my highest recommendation. If you have a project that needs completed in your crawlspace or attic, give them a call and see what they have to say. I suspect you won't be disappointed. Also check out their YouTube channel. They have lots of videos that will likely provide some answers to questions you might have about the type of work they do. read more

We recently purchased an older home in Fountain City and needed some basement/crawlspace work done. CrawlSpace Ninja was selected for the work. From beginning to end they were most excellent! Jamie assessed the situation and did not oversell what was needed. And was very thorough in answering our questions. A few days later Michael the owner came by to verify the situation and was very helpful and honest. Then the Ninjas arrived a few days later to start the work process. Alex, Nick and Ben are terrific ninjas indeed! They are extremely courteous, thorough and efficient. They laid down vapor barrier,sealed some vent openings, installed a dehumidifier, installed a support post and added nails to a ledger board for additional strength as per engineer report. And actually they did a few extra things at no additional cost. We primarily interacted with Alex ninja and he was a delight as he explained everything they were doing and addressed all of our concerns in a clear and simple manner. And all of them were very speedy and efficient in their work. The total cost was also quite reasonable and acceptable. From our experience with CrawlSpace Ninja we highly recommend their services. Many thanks Ninjas, well done. Sincerely, John and Tina read more

This review is specifically about customer service after installation. I recently had an issue with the sump pump installed by Crawl Space Ninja and needed a technician to come out. I was told the Knoxville office--the same one that handled my encapsulation--couldn't send anyone until June 9. That's nearly a full month wait for a sump pump issue. Because, as we all know, water intrusion is famously willing to wait its turn. And to top that off: I was informed they have exactly one technician covering the entire service area. One. So if your system fails, your best option is apparently to hope it doesn't rain and that no one else is ahead of you in line. When I questioned this, I was told--very matter-of-factly--that there was nothing they could do and staffing levels are "out of their control." No urgency, no workaround, no attempt to help. Just...wait. Here's the bottom line: if a company installs a critical system in your home, being unavailable for a month when it fails isn't just inconvenient--it's unacceptable. Great marketing and installation don't mean much if this is what support looks like afterward. Consider that before you commit read more

Wow. Just, Wow. We had the owner, Michael Church, give us his recommendation after thoroughly checking out the problem, and Jamie came and assessed it as well. After excellent advice and explanation of the process that Crawl Space Ninja recommended, we pretty much begged our builder to hire them to tend to our crawl space problems. We had 3 very hard working, careful, perfectionists come to our house to remedy our situation in the crawl space. Alex, Nick, and Ben were beyond excellent at their work. They were here all day, leaving at 6:30 after encapsulation, putting in a drain and sump pump. They had the best attitudes and work ethic we had seen since moving to this state 4 months ago from the north. While I pray we don't have any more problems, I would definitely call on them again. After they left, we went into the crawl space and found it to be a stunning job. It was impeccably clean (!!) and well cared for. We are very impressed!! Thank you, guys. You are the best. read more

Crawl Space Ninja is outstanding! Our crawl space had black mold in one of the corners. My husband did quite a bit of research and found Crawl Space Ninja's website. The videos from Michael Church were extremely helpful, informative and very easy to understand. First, Jamie came out to evaluate and provide a quote. We did not feel any pressure to sign with him. He allowed us to talk it over and get back to him the following day. Patrick was the head guy for the crew who completed the work. He would always call in advance to showing up. He was on time, thorough and very diligent in explaining things and what the crew would accomplish each day they worked. Dallas and Jane, ladies in the office, were extremely friendly and helpful. Michael Church even spoke with me directly to answer follow-up questions we had. We highly recommend Crawl Space Ninja to anyone looking to address crawl space issues. You will not be disappointment. They are awesome!!!!!!! read more

Stephen was my sales rep and Matt was also an installation POC, throughout the encapsulation effort and I could not have been more pleased. They provided me a contact phone number and whenever I had questions about the installation they were responsive, courteous and professional. I really believe Stephen went out of his way to make sure the inspection thorough and complete. I also believe he found issues that could have been costly to repair, had it not been detected and resolved before the installation. If he was not available, for whatever reason, which was rare, someone else from the office would takeover and get the job done. His inspection was thorough and the price offered to us was competitive and fair. The encapsulation and Radon mitigation was superb and if any challenges arose, like limited options for installation of the Radon removal equipment, the communication was excellent and it was resolved in a reasonable timeframe. Well done. read more

I discovered Crawl Space Ninja as I began the process of understanding the situation revealed during a general inspection. I followed Mr. Church online for a year before calling CSN to inspect our situation. We worked with Naaman and James Derry who walked us through the process each step of the way. The crew that did the work were very friendly and never imposing and always ready to answer questions. Communication has been great! The job was outstanding! Our crawl space is a different world! Thankfully, their work exposed another issue that we can take care of. We sincerely appreciate the kindness and support we received from James and Naaman through the whole process and for making it all happen. Thank you! read more

I purchased a home and our "bug guy" informed us that we had a mold issue in the crawl space. A co-worker suggested Crawl Space Ninja's so I had them and another company come out to give an estimate. Jamie came out and explained everything! I knew I was going to use CSN no matter what the next company said. I am so happy I did! They were there when they said the would be, super friendly install team, and it looks great! I called with a question and Jamie was at my door the same day! Jane in the office was super helpful and sweet when I asked questions. I would highly recommend Crawl Space Ninja's to anyone that needs work done in their crawl space!!! read more

Michael did a great job explaining the work that was needed to repair our issue with high humidity and water in our crawlspace. On the day the work was scheduled the crew showed up right on time, introduced themselves, and we're working in the space within seconds. The were very efficient and explained the work they had done and went over a few questions I had with the new equipment. They had to show me where the outlet for the sump pump was placed because it was camouflaged so well. When I asked them how they were able to integrate it so seamlessy they said, we're Ninjas... read more

The Ninjas did an excellent job! What surprised me was not only how efficient and meticulous they were in constructing a new wall for our basement, but also how fast they clean up after a day's work. For example, after having come back home from doing errands, the doors were locked, the lights were off, the floor was swept, the backyard gate was secured and the dogs were still there and safe! Michael, the owner of the company, also stopped by prior to the build to make sure everything was going to go as planned. Thank-you CrawlSpaceNinja! read more

We had Crawl Space Ninja put in a French drain using the Hydraway system. We had the traditional black pipe French drain but it couldn't take care of the water flow. We also had them take our downspouts and run them into the ground and out away from the house by about 10'. Adam, Trafton and Ethan did a great professional job. They arrived on time in the morning and completed the job by mid afternoon. They cleaned up after themselves, filled in the ditch, sewed grass seed and covered it all with straw. We're very pleased with their work. read more

This is a review for nothing done. I wanted our crawl space inspected for a variety of things, including rodents, holes, mold. The inspector, Damien, found nothing. Nothing at all. He was honest and represented this company well. It would have been easy to lie, create a problem for profit, or any number of things. He didn't do that, but told me the truth, saving me money and alleviating concerns. I was very thankful for his honest evaluation. This is a person and company I would do business with in the future without question. read more

Amazing, Informed, Experienced!!! Michael Church is a true expert in the crawl space havoc! Learn from his many videos and ask all the questions because knowledge can save your home and health! Purchased several items: vapor barrier , barrier tape, etc. Was given great service and viable information to continue the project with correct procedure! Much of the problems in renovations truly are from inexperienced trades who did patch work when they should have been addressing the foundational issues! read more

First, Janie was super patient and friendly with answering questions and getting someone to do our inspection in a short timeframe even though they were crazy busy. Then, Craig emailed me the inspection and called to go over it with us since we we were from Michigan and not familiar with Tennessee crawl space sealing. He was great and even gave me the names of some local businesses that could help us with some other projects. Totally appreciate Crawl Space Ninjas. read more

Great experience with their service. We had our crawlspace encapsulated by Adam and his team. They were very professional and did a great job on the installation. They walked me through the completed space, told me how to maintain my dehumidifier and cleaned up well afterward. I would certainly recommend them to anyone else looking to take care of making their crawlspace airtight and energy efficient. read more

A plumber found water in my crawl space and had recommended crawl space ninja. I contacted them and Jamie came to our home and did an inspection. After assessing the damage, I decided to go with CSN. The work was completed in a week. The crew kept me updated on progress and the work was given a follow-up inspection. Crawl space ninja has continued to stay in touch with me. read more

I called CSN and got a real person right away on the phone, Mary Beth, who helped me select the items I needed to get my basement sealed and sumped. She was very understanding and helpful and I was DIYing my job. There was no overselling, just clarity on what I needed for my job. I am grateful as it is all done and dry and functions perfectly! read more

We have been working on a crawl space project outside Ninja's coverage area. They have not only provided superior products at great prices but have been very helpful answering questions along the way to make sure we are not having to fix issues later. We have also leveraged many of their YouTube videos along the way!! Highly recommended!! read more

Michael sent a wonderful crew out to remediate the black mold in my closet. The were VERY professional, thorough, and do not waste time. After they finished my closet, the respiratory issues I had (turned out I am allergic to black mold) got better immediately. I HIGHLY recommend Crawl Space Ninja to ANYONE who has a mold or water problem! read more
